1.4 Electronic Stability System (ESP)
Overview of the plan:
The ESP system collects wheel speed signals, brake master cylinder pressure signals, brake switch signals, steering wheel angle signals, and lateral The pendulum and acceleration signals are used to determine the driver's intention and the driving status of the vehicle, and measures such as electromagnetic valve and pump motor control, engine and transmission control adjustment are taken to apply braking force on suitable wheels to correct the vehicle Torque is used to correct excessive or understeer in the vehicle, and proactive intervention is taken to ensure the stability of vehicle handling.
Industry hotspots:
When the car undergoes understeer, the body behaves as pushing out of the corner. At this time, the ESP system will brake the left rear wheel to prevent the vehicle from falling into danger; When Oversteer occurs, the ESP system corrects the dangerous driving state by braking the right front wheel.
ESP generally requires the installation of pressure sensors, wheel speed sensors, acceleration sensors, yaw sensors, etc. The sensor module signal can transmit data signals to the central control unit through the CAN chip.
