What do you mean, the horn appears on the dashboard and the car stalls?

This is the forced close button of ESP system, which is the electronic stability system of the car body.

Body Electronic Stability System (ESP) is the general name of a system or program, which aims to improve the handling performance of the vehicle and effectively prevent the vehicle from losing control when it reaches its dynamic limit. Electronic stability program can improve the safety and handling of vehicles.

It helps the vehicle to keep the dynamic balance by analyzing the information of vehicle running state from various sensors and then sending rectification instructions to ABS, EBD and so on.

ESP can keep the vehicle in the best stability in all situations, especially in the case of oversteer or understeer.

Development:

Automotive electronic stability control system is a newly developed electronic device in recent years, which is the inheritance and further expansion of anti-lock braking and traction control functions. Bosch Company of Germany began mass production of anti-lock braking system in the mid-1980s, which greatly improved the braking stability of vehicles.

However, it was later found that the anti-lock braking system could not solve the wheel slip problem when the vehicle started to accelerate on the road with low adhesion. Although the patent to solve the problem of driving wheel slip appeared in the 1970s, it was not until

Volvo Company developed the first set of electronic traction control system products, and the traction control technology began to be practical.

1986, Bosch integrated the anti-lock braking system and traction control system and applied them to Mercedes-Benz S-Class cars, marking that,

The arrival of ABS/TCS integration era.
