虽然我生活在常年不会有积雪的上海,但对于冰雪试驾其实有过不少经验。通常不少主打运动的品牌诸如宝马、保时捷会倾向于以培训的形式,教会“学员们”一些在冰雪路面上非常拉风的漂移、甩尾等特技动作,纵然对驾驶技巧方面会有所提升,却更倾向于玩乐。而此次参加的斯巴鲁SUV全系冰雪试驾则不同于这些,即便这也是一个以驾控乐趣闻名的汽车厂商,但斯巴鲁其实也对车辆在冰雪道路上的安全性有着其独到的执着。

首届江苏青少年网络信息安全知识竞赛启动

本次试驾的主要就是三款斯巴鲁在华销售的SUV车型,傲虎、森林人以及XV。这三台车都配备了斯巴鲁惯用的水平对置发动机以及左右对称全时四驱系统(Symmetrical AWD)。
整体在冰雪上的表现接近,但由于发动机排量,电子系统以及手刹形式方面存在一定差异,所以其表现也并不完全相同。
车辆简介
其实在此前《玩转四驱》系列选题中我们已对这三款斯巴鲁SUV车型做过非常详细的测试和介绍,这里再简单回顾一下:由于此次试驾的所有车型都采用了CVT变速箱,因此它们都采用了主动扭矩分配全时四驱系统(Active torque split AWD)(手动挡车型则为粘性中央差速器全时四驱系统)。这四驱系统的采用了电控多片离合器式限滑中央差速器。车辆正常行驶时,前、后桥的默认动力分配比例为60:40,动力输出偏重于前轮。当车辆急加速或车轮出现打滑时,电控多片离合器开始介入工作,进行轴间限滑,前、后桥动力配比也会随之变为50:50。

然而,XV相比傲虎及森林人少了X-MODE功能,该功能在开启后会改变电子限滑的判断逻辑,通过控制发动机、传动系统、左右对称全时四驱系统以及制动系统等等,能够显著提高电子限滑的介入速度,使整车四驱系统的反应更为迅速。
本次所有车辆都换装了来自倍耐力的Ice Asimmetrico系列雪地胎。其实在海拉尔这样常年冬季积雪的地区,车主尽量都为自己的车辆配备雪地胎,毕竟在冰雪路面上,雪地胎凭借独特的橡胶配方及花纹有着四季轮胎无法比拟的抓地力。

项目介绍
此次冰雪试驾除去道路铺装路面的常规试驾以外,主要由三个项目组成,傲虎与XV的较为相似,都是在覆盖了薄雪的冰面上设计了类似金卡纳的小型短途赛道。而森林人则是在爬雪山。
三个项目的主旨都是为了体验斯巴鲁四驱系统在这种极端路面情况所能提供的驾驶辅助。不过既然一年也没几次机会能在这种场地试驾,在确保安全的前提下也能小小的“霍”一把,体验下平日里无法感受到的乐趣。
傲虎试驾
本次试驾的三款车型都无法彻底关闭VDC车身稳定系统,至于为何,斯巴鲁工作人员表示由于这三款车并非纯粹追求运动的车辆,彻底关闭车身稳定系统在大多数情况下并不会带来更多的驾驶乐趣,反而会让驾驶风险变高,出于安全至上的宗旨,即便摁下了VDC OFF的按钮,车辆只是会允许略微打滑,随即便会介入进行姿态矫正甚至切断油门踏板响应。
傲虎的试驾项目主要体验的是四驱系统所能带来的稳定性以及感受车身稳定系统对介入时的速度和力度。
纵然车辆已经换装了雪地胎,但对于地面的附着力始终无法与柏油路等铺装路面相提并论。车速过快入弯便会发生转向不足也就是俗称的推头现象。外加四驱系统最多只能为前后桥分配50:50的动力,因此它也无法像后驱车那样可以简单粗暴的通过深踩油门加大车尾摆动幅度来更好地入弯。
而这时稳定系统的介入就显得尤为重要了,通过及时的对每个车轮的制动力进行自动分配以及控制四驱系统的各车轮扭矩和发动机动力输出,车身只要略微有点失控的迹象便会被立马遏制。即便驾驶者的技术并不算特别好,反应也有些慢,但凭借这套电子稳定系统也能够顺利跑完整个项目以至于不会失控。
在尝试了2圈电子稳定系统保护下的体验后,我打算关闭了试试。可正如上文所提到的,稳定系统无法完全关闭,车辆始终处于“受保护”的状态,想要横着过弯撒欢是有一定难度的。外加傲虎还没有机械手刹,故意让前后轮产生过大的轮速差也不太容易……因此要让车尾摆动起来似乎只有一个办法,那就是利用车辆的重心转移。
听着似乎很玄乎但实际操作起来并不难,简单来说就是当时速较快时,入弯前重刹车让车辆重心转移至车头,随后转动方向,由于车辆处于“头重脚轻”的状态,后轮会很容易突破抓地力而甩起来形成转向过度的姿态,此时要立刻衔接上油门让车身姿态修正一些,否则稳定系统差不多就该介入了。

在这个项目中由于车速较快,因此无法体会到X-MODE(时速超过40km/h会自动解除),并且车辆基本也没有陷进雪地里的危险,无需脱困。
XV试驾
在本次冰雪试驾中,XV的项目体验可以说是乐趣最多的。三台车中它的车身最为小巧,开起来也最灵活。虽然2.0L吸气发动机的动力是三者中最弱的(傲虎和森林人都是2.5L发动机),但在冰雪路面上这点动力差异其实并不会产生太多影响。最关键的是,手刹在这里真的增加驾驶乐趣的神器。
第一圈按照惯例没有关闭车身稳定系统,地板油起步时牵引力控制及四驱系统能确保四轮不会有太过明显的打滑,差不多100米后则是紧急制动,考量的也是车辆在冰雪路面上制动力分配的好坏,车身越稳,车轮越不打滑则表现越好。
在随后的弯道中如果车速过快,车辆依旧会先推头,不过稳定系统介入的速度也和之前体验的傲虎一样迅速。不过由于此前有另外一组同行已经在这个冰雪路面上开过好几圈了,因此原本冰面上覆盖的雪层被刨去的有些多,大面积的冰面裸露在外。
而在这种接近于零附着力的路面上一旦车速过快,无论是车身稳定系统还是四驱系统都会有些无能为力,车辆会直接对着赛道外冲去,除非等车轮再次接触到覆盖雪层的冰面。这也提醒着驾驶者车辆的硬件再好也不是万能的,要有足够的安全驾车意识才是关键。
在体验了一圈过后我便关闭了VDC,首先起步时能够明显感受到车轮的滑动,以至于需要修正方向盘才能走出一条直线。制动时的稳定性也不如此前来的好,不过随后的弯道在入弯前先拉手刹再反打方向让车横着过的感觉真的是太美妙了!虽然不乏有些失误,但如此轻而易举便能让车尾甩起来的情况在平日里真的不多见,这还是要归功于附着力较低的冰雪路面。

越玩胆子越大,失误也越来越夸张,甚至还直接甩到调头了……这也再次提醒大家,千万别在公共道路上尝试这些较为危险的动作,封闭的开阔场地可以随便练习,但在大马路上这么开就绝对算得上危险驾驶了。感兴趣的朋友可以看看上面的视频,我个人觉得在视频3分钟时的那下飘移入弯还是挺完美的,可惜一旁的教练却说手刹拉大了、拉早了……然而看了几次视频后我觉得应该是他还没反应过来我就已经把弯过了但却又不好意思承认自己话说早了(笑)。
森林人试驾
在森林人的试驾环节中则主要会考验到车辆的通过性、四驱系统脱困能力以及车辆的舒适性。而在驾驶技巧方面,这个项目的难度不算很高,只要沿着积雪中的车辙(之前的车开过以后留下的轨迹)行驶即可。
虽然说森林人更像是一台城市SUV,但却不要小觑它在非铺装路面上行驶的能力。它的最小离地间隙为220mm,这个参数与硬派越野SUV牧马人是一样的。外加接近角23°,离去角25°,纵向通过角23°,完全能够应对厚厚的积雪路面。
X-MODE在这个项目中也派上了用场,由于需要在积雪路面上爬坡,车轮或多或少会出现打滑的现象,在开启该功能后,车轮只要短暂打滑车辆便会立即对四轮动力进行重新分配,整个爬坡过程非常顺畅,坐在车内的驾驶员或乘客根本体会不到打滑,只有在车外才能观察到。

而在连续的颠簸路面中,其实绝大多数车辆都没法提供特别好的舒适性,毕竟悬架的物理结构摆在那儿,车身的上下左右摆动或多或少都有一些,视频中也可以听出坐在我身旁的教练说话都带颤音了。不过总的来看,森林人对于这类震动已经在极力抑制,车内并不会感到那些生硬的来自地面生硬的撞击,还算能接受。

其实从硬件方面,斯巴鲁的四驱系统能够在低附着路面上提供更好地稳定性,而无法完全关闭的VDC车身稳定系统则会在车身即将失控时及时对其进行修正。不过车辆的硬件系统也并非万能的,在抓地力几乎没有的冰面上,一旦车速过快,这些功能也无法很好地拯救失控,因此在有积雪的公共道路驾驶还是得放慢车速,良好的行车安全意识才是王道。
总结
其实本次斯巴鲁冰雪试驾的主旨还是以体验其独到的四驱系统以及车身稳定系统在极端低附着路面上所能带来的安全表现为主。虽然与印象中斯巴鲁好像更强调驾驶乐趣、操控性等等,但其实这家看似小众但其实却有着不少拥趸的汽车厂商却向来有着“以人为本,追求安全”的造车理念。更何况还能在特定情况下体验一把冰雪中短暂横走的快感,也足以让我这个见到茫茫大雪都激动得不行的南方人回味无穷。

Taiyuan Subaru EyeSight version with the ceremony.
Welcome to taste
Tasting hotline: 0351-7998886, 7998880
Although my life is not the perennial snow in Shanghai, but to actually have a lot of experience in ice test. Usually many flagship sports brands such as BMW, Porsche will tend to be in the form of training, teach students in the snow and ice drift, beautiful tail and other stunts, even if the driving skills will be improved, but more inclined to play. To participate in the Subaru SUV series ice test is different from these, even if it is a driving fun famous automobile manufacturers, but Subaru is also on the safety of vehicles in the snow on the road has its unique.
The main drive is the three Subaru sales in China SUV models, outback, forest and XV. The three cars are equipped with Subaru used horizontally opposed engine and symmetrical AWD system (Symmetrical AWD).
The overall performance on the ice near, but due to engine displacement, there are some differences between the electronic system and the handbrake form, so its performance is not exactly the same.
Vehicle profile
In fact, before the fun series of topics we have four of the three Subaru SUV models have done very detailed testing and introduction, here a brief review of the test drive: because all models have adopted the CVT gearbox, so they are using active torque distribution AWD system (Active torque split (AWD) the manual transmission models for viscous central differential AWD system). The four-wheel drive system adopts the central differential electronic limited slip clutch. When the vehicle is running normally, the default power distribution ratio of the front and rear axles is 60:40, and the power output is more emphasis on the front wheels. When the vehicle is speeding up or the wheels slip, the electric control multi disc clutch begins to work, and the axle is limited. The front and rear axle power ratio will also be changed to 50:50.
However, compared to XV outback and forest less X-MODE function, this function will change the electronic limited slip of the logic in the open, by controlling the engine, transmission system, symmetrical AWD system, braking system and so on, can significantly improve the involvement of electronic limited slip speed, the vehicle four-wheel drive system was more quickly.
All the vehicles are switched from the Pirelli Ice Asimmetrico series snow tires. In fact, in Hailar this year winter snow cover area, the owners try for their vehicles equipped with snow tires, after all, in the snow and ice, snow tires with rubber formula and unique patterns with four tires unmatched grip.
Project introduction
相信在未来的PC上我们已经不需要操作系统以及任何其他应用程序,开机只需要一个浏览器就可以解决所有问题。相信将极大的引起一场Web应用的变革,甚至是整个Internet产业的变革。
The ice test drive to remove conventional road pavement pavement outside, mainly consists of three projects, outback and XV are similar, are covered in a thin snow ice design similar Gymkhana small short circuit. While the forest is climbing the snow capped mountains.
The three purpose of project is to experience Subaru 4WD driving assistance system can provide in the extreme condition of the road. But since one year did a few opportunities in the test sites, under the premise of ensuring safety can also be a little Huo, pleasure weekdays do not feel experience.
Outback drive
The drive of the three models are unable to completely shut down the VDC vehicle stability system, as to why, Subaru staff said that due to these three cars is not pure pursuit of moving vehicles, completely closed vehicle stability system in most cases does not bring more fun to drive, but will make the driving risk becomes high, for safety first the purpose, even press the VDC OFF button, the vehicle will allow only slightly slipping, then it will intervene to correct posture and even cut off the accelerator pedal response.
Outback test project main experience is the speed and strength of stability can bring the four-wheel drive system and the feel of the vehicle stability system intervention.
Even if the vehicle has installed snow tires, but for the adhesion of the ground can not always with asphalt pavement. Etc.. The speed is too fast in bending occurs understeer is commonly known as Tuitou phenomenon. The four-wheel drive system can only allocate 50:50 power for the front and rear axle, so it can not be like driving that can simply through the throttle and cart tail swing to better into the corner.
While the stability of system intervention is particularly important, the system automatic distribution and control of four-wheel drive each wheel torque and engine power output by the power system for each wheel in a timely manner, as long as the body slightly signs out of control will be curbed immediately. Even if the driver’s technology is not particularly good, the reaction is slow, but with this set of electronic stability system can run a complete project will not be out of control.

OneASP:为信息安全破局而来

After trying 2 laps of the electronic stability system under the protection of the experience, I intend to close the test. As mentioned above, the stable system can not be completely closed, the vehicle is always in the protected state, want to turn sideways because there is a certain degree of difficulty. The Outback is not the mechanical brake, deliberately let the front and rear wheel excessive wheel speed difference is not too easy…… So it seems to be the only way to swing the tail, that is, the use of the vehicle center of gravity shift.
Listening seems iffy but the actual operation is not difficult, is simply at faster speed, Cornering Brake for vehicle before transferred to the front, then the direction of rotation, because the vehicle is in top-heavy state, the rear will easily break the grip and swing to form over steering attitude, this time to join immediately on the throttle to get the body posture correction, otherwise stable system should intervene almost.
信息安全产业破局在普及信息安全意识
In this project because of faster speed, thus unable to realize X-MODE (speed of more than 40km\/h will automatically release), and the vehicle basic is not in danger in the snow, without difficulty.
XV drive
In this ice test, XV project experience can be said to be the most fun. Three car in its body is the most compact, open up the most flexible. Although the 2.0L engine is the inspiration of the weakest of the three (AO and forest are 2.5L engine), but in the snow and ice on the road, this difference does not actually have much impact on the dynamics of the road. The key is that the handbrake here really increase the artifact driving pleasure.
The first circle is not closed in accordance with the practice of vehicle stability system, floor oil starting traction control and four-wheel drive system can ensure the four round there will not be too obvious slip, almost 100 meters is the emergency brake, the vehicle braking is also considered in the snow and ice force distribution is more stable, the body, the wheel is less slippery the performance is better.
In the ensuing corner if the speed is too fast, the vehicle will still first push, but stable system intervention as well as the speed of the outback experience before quickly. But because after another group of peers has been in the snow and ice road opened several times, so the ice snow covered originally is planing to some of the more massive ice exposed.
In this close to zero adhesion on the road once the speed is too fast, whether it is the body stabilization system or four-wheel drive system will be some vehicles directly to the incapable of action, rushed to the track, the wheel again exposed to snow covered ice until. It also reminds the driver of the vehicle hardware is not good enough to have enough safety driving awareness is the key.
After experiencing a lap I closed the VDC, the first start can obviously feel the wheel slide, so you need to correct the steering wheel to get out of a straight line. The stability of braking is not so good to come, but then bend before turn in the opposite direction and then pull the handbrake to let the car sideways the feeling is really wonderful! Although there are some mistakes, but it is easy to be able to let the car tail thrown up in the usual situation is really rare, this is due to the low adhesion of ice and snow road.
More play more courage, mistakes are more exaggerated, even directly thrown into a u-turn…… This also reminds us again, do not try these dangerous actions on the public road, closed open space can be practiced, but on the road so open is absolutely dangerous driving. Interested friends can see the video above, I personally feel that drift in video at 3 minutes into the corner is very perfect, but the side of the coach said handbrake pull big, pull early…… However, after watching the video a few times, I think it is because he has not yet come to the end of the reaction, but I am too embarrassed to admit that I have spoken earlier.
The forest people drive
The drive link in the forest will mainly test to the vehicle through, four-wheel drive system and vehicle comfort relief capability. In the driving skills, the difficulty of this project is not very high, as long as the snow along the track (before the car left the track after leaving) can be.
Although the forest is more like a city of SUV, but don’t underestimate its ability to driving on the pavement on. The minimum ground clearance for the 220mm, and the parameters of hardcore off-road SUV Wrangler is the same. Close to 23 degrees angle, departure angle of 25 degrees, through the vertical angle of 23 degrees, fully able to cope with the thick snow pavement.
X-MODE also come in handy in this project, due to the need for climbing in the snow on the road, the wheels will appear more or less slipping phenomenon, in the feature, as long as the wheel slip short vehicle will immediately on the four round of dynamic re allocation of the whole process of climbing is very smooth, the driver sitting in the car or the passengers at all experience not to slip, only on the outside of the car can be observed.
In the continuous bumpy road, in fact most of the vehicles can not provide particularly good comfort, after all, the physical structure of suspension there, the body of the swing up and down somewhat, the video can also listen to sit on my side of the coach spoke with the voice of AF. But overall, the forest people for this type of vibration has been suppressed, the car did not feel awkward from the ground blunt impact, still can accept.
In fact, from the aspect of hardware, the Subaru Quattro system can on the low adhesion road to provide better stability, VDC stability system and can not be completely closed will be in the body will get out of control in a timely manner to correct the. But the hardware system of the vehicle is not omnipotent, in almost no grip on the ice, once the speed is too fast, the function also is not good to save out of control, thus driving on public roads with snow still have to slow down traffic, good safety awareness is the kingly way.
summary
In fact, the main theme of the Subaru ice test or experience based its unique system and four-wheel drive vehicle stability system in extreme low adhesion road safety performance can bring. Although the impression Subaru seems more fun to drive, control and so on, but in fact, this seemingly small but actually has a lot of fans of the automobile manufacturers has always been a people-oriented, the pursuit of security concept cars. Not to mention in the particular case of an experience of snow and ice in the short cross walk pleasure, is enough to let me see the snow was not the southern people lead a person to endless aftertastes.
