【Pacific Auto Network Technology Channel】Although the current car crash safety technology has been very far developed, the damage caused by the vehicle collision is still serious, so the classification of the car crash test results and the promotion of product safety are very necessary. Among them, compared with the trolley crash test and the bench test of parts, the real car crash test has the most realistic and intuitive technical characteristics, so the results of the test are also the most convincing.
First of all, I would like to introduce the components of the C-NCAP crash test project, which are three test parts: occupant protection, pedestrian protection and active safety.
Highlander received a five-star safety rating in the C-NCAP crash test, and from the total score of the test, the vehicle achieved more than the average level in the three test items, and its main loss of score came from the front 40% crash test and the head protection for pedestrians.
Occupant protection crash test
In the crew protection test project, this test consists of four items, namely: complete frontal collision test, frontal 40% collision test, side collision test, and whipping test.
1. Frontal 100% overlapping rigid barrier crash test
2. Frontal 40% overlapping deformable barrier collision test
In addition, the new generation Highlander is also equipped with Toyota Zhixing Interconnection, and the dcm (data communication module) is introduced throughout the series, which can provide timely assistance in emergency situations. After the frontal 40% crash test, the background system also detected a serious vehicle collision and inquired about it by telephone at the first time, which is enough to reflect the role of Toyota's system at a critical moment.
3. Deformable movable barrier side collision test
4. Whipping experiment
In the process of the test, when the dummy was subjected to dynamic impact, it was reclined due to inertia, but the headrest of the seat did not interfere with the dummy's head, and the opening angle of the seat back, although it changed to a certain extent, was also within a reasonable range. In the end, due to a certain displacement of the seat rails, there was a loss of points, resulting in Highlander's whipping test score of 4.505 points (90.1%).
In addition, since the new highlander is equipped with seat belt reminder devices and equipped with front and rear integrated side air curtains, the vehicle scores 4 points in the rider protection add-on after being evaluated according to the external dimensions, unfolding shape and dynamic protection of the air curtains.
Pedestrian protection test
In the head type test, the vehicle is adjusted to the normal driving attitude, and the head type impacts the head test area of the vehicle at 40km/h. In the Pediatric HeadStyle Test and the Adult HeadStyling Test, this performance was evaluated by the head injury index value in the head shape.
In the end, the leg type test scored 3 points (100%), and the overall pedestrian protection project scored 12.353 points, with a scoring rate of 82.35%, which was nearly 10 percentage points ahead of the same class models.
Active safety testing
The active safety part mainly includes the evaluation of vehicle rear-end automatic emergency braking system (AEB CCR), pedestrian automatic emergency braking system (AEB VRU_Ped), AEB configuration coefficient, ESC and other aspects.
Its main deduction is the vehicle-to-car automatic braking ability, resulting in the vehicle being too close to the car in front when it is completely stopped, and there is a large safety hazard. The final score for active safety was 14.884 points, or 99.23%, much higher than the 91.32% scoring rate of the same level.
Summary of the full text
In the front 40% crash test of the new generation Highlander, the loss of points due to the offset of the rear passengers is more serious, and due to the size of the body, it also loses a lot of points in the process of pedestrian head protection, but it has obtained full scores in the side collision test, and its comprehensive performance is still very good.
Compared with the same level of pure electric vehicles, the performance of the new generation of Highlander in terms of active safety can be said to have brought many surprises, but it is hoped that the future can be continuously optimized at the lost points to ensure the safety of the vehicle.
