Elk test is a car professional test project, many consumers are equivalent to handling performance testing, while The appearance of the arrival is judging, “double wheel” represents poor manipulation performance? ! This is actually a misunderstanding. Today, the author takes everyone to see the essence through the phenomenon, let’s see what the elk test is?
[123
Elk Test originated in Sweden and is a safety test that measures the emergency avoidance of vehicle emergency avoidance.
Its name is from the moose, which is huge, distributed in most of the Scandinavian Peninsula and North America of the Scandinavian Peninsula of Northern Europe, which will often be unresolved in front of the vehicle, collision with high-speed vehicles , Causing a serious traffic accident.
Although the elk test was born in the 1970s, it is truly The house car is paying attention to it has also said from a test in 1997. At that time, the famous elk testing mechanism TEKNIKENS VAUML; RLD was tested against Mercedes-Benz A, and the car was rolled over 60km / h. Subsequently, Mercedes-Benz ordered the A-class sedan and re-adjusted the suspension and installed the ESP body stability system. In a sense, Mercedes-Benz A-level test has played a positive role in the popularity of ESP.
The test content of the elk test is: the driver enters the test with a constant speed District, high-speed dodge without stepping on the brakes and throttle. The test personnel were repeated, and the speed of the vehicle was successively improved, and until the vehicle was out of control, and finally determined the reliability of the lost car speed value.
In other words,
Elk test is to force the vehicle to the limit, the speed of the test record is the maximum vehicle speed when the vehicle is reached, not without loss of control
. In this regard, the condition of the tire is separated, and the side slip and other conditions belong to the normal phenomenon of test.
Further, the results of elk test are also affected by many factors. For example, the soft and hardness of the suspension, the center of gravity, the body length, the tire thickness, the tire grip, the vehicle drive form, vehicle load, ESP, driver driving technology, track environment, etc.
[123 Not long ago, Changan Automobile UNI sequence second model Uni-K conducted elk testing. Netizens surrounded the fierce saliva war around the uni-K “double-wheel” lens, many netizens also had a questionable performance of UNI-K. We may wish to look at the uni-k elk test.
[123 First, based on the origin of elk testing and test content, we can clearly recognize that “the wheel lifts” belongs to the normal phenomenon of elk test. And from the previous model’s elk test case, such as Jeep Grand Cherokee, Toyota RAV4 honor and other models have also appeared different levels of sliding, and the tires are separated.
Next, let’s take a look at Sweden Teknikens Vauml; RLD institution test, excellent models.
Looking at it, the front row of the list is basically a variety of sports cars. However, the highest record holder of the elk test is the Citroen Xantia. If the “elk test results are equivalent to the argument” argument, the Citroen Xantia’s control is better than the Porsche, McLaren, etc. This is actually right.
In this regard, the elk test is only a basic test of car safety. The control is not only related to the model category, but also affects whether the power response is sensitive, linear, speed Whether the box is smart, the steering is precise, and so on.
In fact, the elk test speed of household models can exceed 70km. It is very good. The industry average of SUV elk test is about 68km / h.
Currently, the domestic SUV market can achieve this level in the sales model. Not much. In the SUV field, Honda’s elk test limit is 64.7km / h; Audi Q5L elk test limit passes speed is 72.4km / h; Changan Uni-K elk test limit passes up to 73km / h, performance It is already quite excellent.
[123 ] The vehicle participating in the elk test will have been verified to the limit speed. At this time, the lateral acceleration of the vehicle can generally reach about 0.8 g, which belongs to a typical limit driving. Ordinary users use 99 percentage working conditions everyday, the side of the body is within 0.3 g. When the lateral acceleration exceeds 0.3 g, the driver’s first reaction is to perform deceleration operations, thereby circumventing the occurrence of an accident. In front, we also mention the effects of elk tests have been influenced by many factors.
In this way,Ordinary users do not substantially perform elk testing. but!
Elk test results in the limit state can indeed reflect a brand of charging.
Changan Uni-K selectively gripped strong Horse-name MC6 tires, and matches the Bosch ninth generation ESC system, ensuring that it has good tracking and safe and fast avoidance in elk trials.
During the development of the ESC system, Changan cars in the body attitude Control and the fastest use of vehicle speeds to balance and hit. It does not pursue body attitude control, intentionally intervene in advance by ESC to reduce the speed of the vehicle, but in the premise of safeguarding, to keep the corresponding driving pleasure for users.
It is to mention that Changan Automobile has established a global synergy system of “five countries”. Each of Changan Auto has experienced 17 large systems, more than 180 laboratories, and more than 4,000 tests. It is because of such a harsh test system, Changan Uni-K hard product quality is guaranteed.
[123 The biggest purpose of elk test is to improve driving safety, but only one of the rings of car safety performance, and whether the car is safe depending on the collision test, and the main passive safety configuration is rich. In addition, through the introduction of elk testing, it is necessary that everyone has broken the “test vehicle wheel to ground the ground means poor”, “elk test is equivalent to the control performance test”. We look at the R & D capability of Changan Auto, UNI-K’s elk test results, ESC system debugging strategy, and the setting of high-grasp of land-based tires, Chang’an Uni-K is a rich driving.The SUV for fun, the space settings of the large five, and the rich functional configuration, which also let us see this is a new work.
