What Causes the Stability System Warning Light to Illuminate?
1 Answers
When the indicator light remains constantly illuminated, it may indicate that the Electronic Stability Program (ESP) has been deactivated, often due to accidental operation by the driver. Below is relevant information about the ESP system: 1. Definition: The ESP system is essentially a type of traction control system. Compared to other traction control systems, ESP not only manages the drive wheels but also controls the non-drive wheels. For instance, in rear-wheel-drive vehicles prone to oversteer, where the rear wheels lose control and cause the car to fishtail, ESP will apply braking to the outer front wheel to stabilize the vehicle. In cases of understeer, to correct the tracking direction, ESP will brake the inner rear wheel to adjust the vehicle's trajectory. 2. Function: The ESP system is a crucial component in vehicles, typically supporting the functions of ABS (Anti-lock Braking System) and ASR (Acceleration Slip Regulation). By analyzing vehicle state information from various sensors and issuing correction commands to ABS and ASR, it helps maintain dynamic balance. ESP ensures optimal stability under various conditions, with particularly noticeable effects in situations of oversteer or understeer. The installation of steering sensors, wheel sensors, skid sensors, and lateral acceleration sensors is generally required for ESP operation.
