What's the use of this close button on the car?

OFF is the close button of the body stability control system. By default, the system is on. Press and hold this button to turn it off.

Many cars are equipped with this system, but different brands and different technology providers have different names, such as Honda called VSA, Toyota called VSC, Nissan called VDC, BMW called DSC and so on. Although the name is different, the working principle is similar. This is an active security configuration.

Its working principle is that when the speed difference between the left and right wheels exceeds the threshold set by the computer, the computer will think that the vehicle has sideslip or tail flick, and will take single-wheel braking according to the actual situation, and at the same time reduce the engine output torque to control and avoid the vehicle sideslip and tail flick. In addition, OFF also integrates ABS (Anti-lock Brake System), BAS (Brake Assist System), ASR (Anti-skid Adjustment System), TCS (Traction Control System) and other systems, and the integration technology of different brands of vehicles will be different.
