PROBLEM TO BE SOLVED: To provide a drive control device capable of minimizing an impact of a three-phase short-circuit to a traveling performance of the vehicle.SOLUTION: A drive control device comprises: three-phase short-circuit execution means (14, 20) to execute a three-phase short-circuit for an inverter (10) when a vehicle speed (V) becomes a predetermined first threshold value (V1) or slower after cutting off a high voltage circuit of a power supply circuit (13); and three-phase short-circuit cancellation means (14, 20) to cancel the three-phase short-circuit when the vehicle speed (V) becomes a predetermined second threshold value (V2), which is greater than the first threshold value, or faster during execution of the three-phase short-circuit.SELECTED DRAWING: Figure 3 |
