Now the one key start of the car has almost become a standard configuration. It is no longer a high-end novel configuration. One key start is simple and convenient to operate. As long as the key is in the car, it can be started one key. When the engine is turned off, it is also a press to close. Such a convenient function, what if I accidentally encounter this key in driving?

In fact, there are already some car friends on the Internet who have done the test. The test model is a wellang GS. In a relatively safe environment, the test road condition is very open and flat.

Experiment 1

Keep the vehicle speed at 20km/h, and then press the one button start button. After that, the vehicle does not have any abnormality, the instrument display does not have any abnormality, and the vehicle is running normally, so it can be judged that even if it is accidentally touched, there is no problem.

Experiment 2

The vehicle speed is still kept at 20km/h. press the button twice continuously. As a result, the engine suddenly stops and the main steering wheel loses its function. The steering wheel is locked, but the brake can still work, but it becomes heavy and the main pump loses its function. In addition to the above situation, the power supply is still on and the instrument panel displays normally.

Experiment 3

Still keep the safe speed, press and hold the key for 3 seconds to start, and the engine stops.

Experiment 4

This time, the speed has been increased by 80km/h, the result is the same as the above experiments I, II and III. therefore, it can be judged that whether the engine stalls or not has nothing to do with the speed. If this happens in high-speed and mountainous areas, it is very dangerous.

Through the experiment, we can see that the one button start-up configured by the original factory has a protection device, and if you just press it for a short time, it will not turn off.

According to the different models, some models are designed differently. Some models press and hold for 3 seconds to turn off the engine. Others need to operate with the brake at the same time to turn off the engine.

I concluded: we must take good care of the children during driving. It's better to let the children sit in the back seat so as to avoid emergencies
