The car's ESP is used automatically. The actuator of ESP is the brake system of the four wheels. Unlike cars without ESP, the brake system of a car equipped with ESP has a pressure accumulation function. The actuator of ESP is a braking system that can brake the wheels independently. Unlike cars without ESP, the braking system of cars equipped with ESP has a pressure accumulation function.
To put it simply, pressure accumulation means that the computer can pressurize the brake pipes of the wheels for the driver when the driver does not apply the brakes as needed, and apply precise braking force to each wheel individually, so that The vehicle keeps moving steadily. In addition, ESP can also control the engine's power output and intervene in the transmission gear.
Extended information
The social background of the development of automotive ESP:
The German Bosch Company began mass production of anti-lock braking systems in the mid-1980s. This device greatly improves vehicle braking stability.
However, it was later discovered that the anti-lock braking system could not solve the wheel slip problem that occurred when the vehicle started and accelerated on low-adhesion roads. Although patents related to solving the problem of drive wheel slippage have appeared since the 1970s, it was not until VOLVO developed the first set of electronic traction control system products that traction control technology became practical.
In 1986, Bosch integrated the anti-lock braking system and traction control system and applied them to the Mercedes S-Class sedan, which marked the advent of the ABS/TCS integration era.
