Method for regulating offset of current detection signal in driving power transmission controller

Method for regulating offset of current detection signal in driving power transmission controller

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 am...

description 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.
