DRIVING CONTROL DEVICE AND DRIVING SYSTEM FOR VEHICLE

In a driving control device that controls a driving system for a vehicle, a voltage detection unit acquires a voltage value for each of cells of the battery as a cell voltage value, an abnormality determination unit determines an abnormality in voltage detection system for each of the cells based on the cell voltage value, and a rank setting unit sets ranks of the plurality of cells based on a parameter involved in failure in the battery. A fail-safe running unit determines a mode of fail-safe running of the vehicle based on the rank of the cell to be detected by the voltage detection system determined to have an abnormality, and a rotating electric machine control unit controls the rotating electric machine based on the mode of fail-safe running of the vehicle determined by the fail-safe running unit.
