Claim 0:
1. A driving control device for controlling a driving system for a vehicle, the driving system comprising: a battery;
a rotating electric machine that drives the vehicle by power supplied from the battery; and
a switch that switches an electrical connection state between the battery and a power supply source that supplies power to the battery to a conductive state or a cutoff state,
the battery control unit comprises:
a battery control unit that controls the battery; a running control unit that controls a running state of the vehicle; a power supply control unit that controls the power supply source; and a switch control unit that controls the switch,
wherein the battery control unit comprises:
a voltage detection unit that acquires a voltage value of the battery as a battery voltage value;
a current detection unit that acquires a charge/discharge current value of the battery as a battery current value;
a monitoring unit comprising a voltage monitoring unit that determines an abnormality in voltage detection based on the battery voltage value and a current monitoring unit that determines that power is supplied to the battery when the battery current value is on a charge side relative to a predetermined current threshold value,
the running control unit controls the rotating electric machine in such a manner that the vehicle is brought in a fail-safe running state when the voltage monitoring unit determines that the voltage detection is abnormal,
the power supply control unit, when the voltage monitoring unit determines that the voltage detection is abnormal, controls the power supply source to be in a power supply prohibition state in which power supply to the battery is prohibited, and
the switch control unit cuts off the switch, in a case where the current monitoring unit determines that power is supplied to the battery when the power supply source is controlled to be in the power supply prohibition state.
