Electronic Stability Control (ESC)

WABCO is an industry leader in advanced safety products integration


Electronic Stability Control (ESC) is an active vehicle safety system that automatically intervenes when there is a high risk of directional instability that could lead to loss of vehicle control or rollover. The ECU constantly compares the vehicles actual movement to performance models using various vehicle sensors. If the vehicle shows a tendency to leave the driver’s intended path (oversteer or understeer) or exceed a critical lateral acceleration threshold, the system intervenes by selectively applying appropriate brakes to better align the vehicle to the driver’s path of travel, or speed thereby assisting the driver in maintaining control of the vehicle.

Features & Benefits

  • Automatically intervenes to assist the driver in maintaining directional control of the vehicle when encountering slippery road conditions or taking an evasive action
  • Assists the driver in reducing the risk of rollover while in a curve or taking evasive action
  • Reduces the chances of a jack-knife and drift out condition through selective braking of the tractor and trailer
  • Controlling and reducing tractor-trailer speed when lateral acceleration limits are about to be exceeded
  • ECU has data recording capabilities for various functions
