What does Buick's ESP maintenance mean?

[CodyFitz]

Buick's ESP maintenance means: 1. Fault occurrence: The maintenance of ESP indicates that the Electronic Stability Program (ESP) has encountered a fault and requires inspection and repair. 2. Function of ESP: It helps maintain optimal vehicle stability under various conditions, especially noticeable in cases of oversteering or understeering. Information about ESP: 1. ESP: The Electronic Stability Program is a general term for systems or programs designed to enhance vehicle handling performance while effectively preventing loss of control when the vehicle reaches its dynamic limits. 2. Working principle: Under certain road conditions and vehicle load conditions, the maximum adhesion force that the wheels can provide is a fixed value. In extreme situations, the longitudinal force (along the rolling direction of the wheel) and the lateral force (perpendicular to the rolling direction of the wheel) have an inverse relationship. The Electronic Stability Program can independently control the longitudinal braking force of each wheel, thereby influencing the lateral force and improving the vehicle's handling performance.
