ABSTRACT:
An offset value setting processing, in which whether or not all wheel velocities of front wheels and rear wheels are 0 km/h is determined and whether or not a pressing amount of an accelerator pedal is 0% is determined. If it is determined that the vehicle velocity is 0 km/h and that the pressing amount of the accelerator pedal is 0%, a current detection signal voltage at that time is set to an offset voltage. Thus, the offset voltage value is reset and set again if such a condition is established. Consequently, the offset voltage value including the amount of an error due to a temperature drift is set up, thereby preventing drop in control accuracy due to that error.
