With the improvement of intelligence, the test standards of automotive safety testing institutions are also slowly changing. In recent years, tests of intelligent driver assistance functions have been added to the testing of safety standards for automobiles.
Euro NCAP is an authoritative third-party automotive testing organization in Europe. Recently, the agency tested the highway driver assistance function as one of the functions of ADAS and published the results.
The ADAS functions tested by Euro NCAP focused on emergency braking. It is important to identify and move the vehicle in front of you and take braking measures. Whether to identify and pedestrians or cyclists and take brakes.
Most drivers use adaptive cruise control primarily on the highway. Euro NCAP tests vehicle ADAS capabilities on highways from 2020. Assess whether the driver's driving and the vehicle's self-control are well balanced, and to what extent accidents in hazardous situations are prevented.
The test results are classified as very good, good, medium and entered.
This year, the test vehicles include the Hyundai Ioniq 5 and Polestar 2, BMW iX3, Ford Mustang Mach-E, Coupra Forenter, Toyota Yaris.
[1] BMW iX3
The BMW iX3 was selected as the model with the best ADAS capabilities.
Although there is an indoor camera, its disadvantage is that it is not used to monitor the driver, only to check if the driver is steering correctly. It has been proven to be good to maintain a balance between the vehicle's own lane and the driver's controlled steering.
Using both map data and sign recognition, it is also equipped with the ability to automatically change the speed when entering a curve, intersection or roundabout. It also prevents accidents in situations such as when the vehicle in front of it cuts in or changes lanes (cuts out). It even passes through S-shaped corners at speeds of 100 km/h or more while maintaining its center of gravity. However, the lane change feature is not supported.
[2] Ford Mustang Mach-E
The Ford Mustang Mach-E received a good rating. The model also has an indoor camera, but it is not used for driver monitoring, and driving conditions can only be checked by manipulating the steering wheel. The balance between keeping the vehicle in its own lane and the driver's operational steering was assessed as good.
The use of map data in conjunction with sign recognition improves accuracy. However, there is no function to automatically adjust the speed of corners and intersections. In situations such as when the vehicle in front of it cuts in or changes lanes, it can be very good at preventing accidents. Pass the S-shaped bend while keeping the center of the lane steady until the speed reaches 80 km/h. The lane changing feature is not supported.
If the driver does not drive and does not respond, it will keep the lane center and slow down. It reduced the speed to only about 10 km/h and didn't stop. When there is a problem with a radar or camera sensor, it warns the driver and prepares the system for normalization.
【3】Cupra Trainer
Cupra Formator also received good reviews. It also does not have an indoor camera, and the driver's operation can only be mastered by steering operation. The balance between keeping the vehicle in its own lane and the driver's operational steering was assessed as good.
At the same time, it supports the use of map data and sign recognition functions, which improves the driving speed. It is also equipped with a function that automatically changes the speed when entering a corner, intersection or roundabout. In situations such as cutting in front of the car or changing lanes (cutting out), it can prevent accidents very well, but it is found that the emergency braking system does not completely prevent accidents. Pass the S-shaped bend while keeping the center of the lane steady until the speed reaches 80 km/h. The lane changing feature is not supported.
In the case that the driver is not driving or responding, it slowly slows down to a complete stop while maintaining the lane. In addition, it warns the driver when there is a problem with the radar or camera sensor.
[4] Hyundai Ioniq 5
Hyundai Ioniq 5 receives a medium rating. It does not have an indoor camera, and the driver's operation can only be mastered by steering operation. When the vehicle maintains its own lane and the driver steers, it is found that the balance is good.
The use of map data and sign recognition at the same time improves driving speed. There is a function of automatic speed change when entering a corner, but there is no function of slowing down at intersections.
Accidents are well prevented in situations such as the vehicle in front of them cutting in or changing lanes. The S-shaped curve passes steadily at speeds of more than 100 km/h while maintaining the center of the lane. Lane change functions are also supported.
However, the blind spot warning function does not have the function of preventing lane changes when a vehicle is detected. In addition, when the driver did not drive and did not respond, the HDA II of the Ioniq 5 completely failed, there was no vehicle control, and the score was reduced.
【5】Polestar 2
Polestar 2 also scored moderately. Without an indoor camera, the driver's operation can only be mastered by steering. A good balance can be seen when the vehicle maintains its own lane and the driver operates the steering.
Improving travel speed improves accuracy by using both map data and sign recognition, but it doesn't have the ability to slow down intersections and roundabouts.
The vehicle identification section in front loses points. It is limited in identifying vehicles parked in front and stopping. In addition, the part where the vehicle cuts into the front is well identified, but it is not well identified when the lane changes. The S-shaped curve stabilizes the lane center up to 80 km/h and does not support lane change function.
[6] Toyota Yaris
Toyota Yaris does not have an indoor camera, and the driver's operation can only be mastered by steering operation. A good balance can be seen when the vehicle maintains its own lane and the driver operates the steering.
It can also use map data and sign recognition to improve accuracy, but it doesn't have the ability to slow down corners, intersections, and roundabouts.
Like the Polestar 2, it identifies vehicles parked in front of it and cannot avoid accidents. However, it is well protected against accidents in situations such as when the vehicle in front of it cuts in or changes lanes. The S-shaped curve stabilizes the lane center up to 80 km/h and does not support lane change function.
If the driver is not driving and does not respond, the ADAS function is completely disabled and vehicle control is not performed. When there is a problem with the radar or camera sensor, it warns the driver.
