1. A vehicle control system comprising:

  • a battery mounted to a vehicle;

    a vehicle alternator configured to generate electric power and charge the electric power to the battery;

    a battery current detection device configured to detect charging and discharging current of the battery;

    a voltage regulation device configured to adjust an output voltage of the vehicle alternator to a specified output voltage; and

    a temperature sensor mounted to the inside of the battery current detection device, configured to detect a temperature of the battery and a temperature of a shunt resistance, whereinthe battery current detection device and a battery clamp connected to a terminal of the battery are assembled together,temperature characteristics of the shunt resistance are compensated on the basis of the temperature of the shunt resistance detected by the temperature sensor,the battery current detection device detects the charging and discharging current of the battery on the basis of the shunt resistance having the compensated temperature characteristics, andthe temperature sensor is mounted onto the shunt resistance which faces a side of the battery clamp or onto a conductor through which the shunt resistance and the battery are electrically connected together.
