What does ESP mean?

[VonEvan]

ESP is the abbreviation for Electronic Stability Program, which is an extension of the functions of the anti-lock braking system (ABS) and traction control system (TCS) in vehicles. It is also part of the vehicle's active safety system. ESP primarily controls the longitudinal and lateral stability of the vehicle, ensuring that it moves according to the driver's intentions. ESP mainly consists of three major components: sensors, actuators, and the electronic control unit (ECU). The sensors include wheel speed sensors, steering angle sensors, lateral acceleration sensors, yaw rate sensors, and brake master cylinder pressure sensors. The actuators include traditional braking systems and hydraulic modulators. The electronic control unit works in conjunction with the engine management system, allowing for intervention and adjustment of the engine's power output.
