Outline of Power Steering Cooperative Control Function
1) General
D The VDIM effects coordinated control consisting of the ECB (Electronically Controlled Brake
System) and EPS. By integrating these preventive safety functions, the VDIM ensures excellent
driving stability and maneuverability of the vehicle.
D The VDIM coordinates the EPS and ECB (Electronically Controlled Brake System) to perform
braking control on split friction roads and front and rear wheel skid tendency controls.
D If the vehicle loses stability due to wheel slippage, this function effects brake control by applying brake
pressure to the wheels. At the same time, the EPS provides steering torque assist control to facilitate
the driver's steering maneuver.
