What is Electronic Stability Control System?
1 Answers
Automotive Electronic Stability Control System is a new type of active safety system for vehicles. It is an extension of the functions of the Anti-lock Braking System (ABS) and Traction Control System (TCS). On this basis, it adds a yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor when the vehicle is turning. The ECU controls the driving and braking forces of the front, rear, left, and right wheels to ensure the lateral stability of the vehicle during driving. The following is a detailed explanation of the Electronic Stability Control System: 1. The system consists of three main components: sensors, an Electronic Control Unit (ECU), and actuators. The ECU monitors the vehicle's operating status and intervenes in the control of the vehicle's engine and braking system. 2. A typical automotive Electronic Stability Control System mainly includes four wheel speed sensors, a steering wheel angle sensor, a lateral acceleration sensor, a yaw rate sensor, and a brake master cylinder pressure sensor in the sensor part. The actuator part includes the traditional braking system (vacuum booster, pipelines, and brakes) and hydraulic regulators. The Electronic Control Unit works in conjunction with the engine management system, allowing intervention and adjustment of the engine's power output.
