Model OutlineEngineChassisBodyBody Electrical Steering EPS Operation –There are the following functions in assist control ItemFunction Basic Control Calculates the assist current from the steering torque value and the vehicle speed, and actuates the motor Inertia Compensation Control Improves the starting movement of the motor when the driver starts to turn the steering wheel Recovery Control During the short interval between the time the driver fully turns the steering wheel and the wheels try to recover, this control assists the recovery force Damper Control Regulates the amount of assist when the driver turns the steering wheel while driving at high speeds, thus damping the changes in the yaw rate of the vehicle body System Overheat Protection Control Estimates the motor temp. based on the amperage and the current duration. If the temp. exceeds the standard, it limits the amperage to prevent the motor from overheating
