To provide a vehicle control apparatus capable of protecting a switching element from temperature rise caused by intermittent motor lock while preventing drivability degradation.[Solution]Included are a motor (4), an inverter (5) that supplies AC electric power to the motor (4) using a switching element and a control unit (6) that performs first torque restriction control to restrict torque of the motor (4) in a case where a first determination condition that the torque of the motor (4) is equal to or larger than first torque and that a rotation speed of the motor (4) is equal to or less than a first rotation speed is met for a first determination time, performs second torque restriction control to restrict the torque of the motor (4) in a case where a second determination condition that the torque of the motor (4) is equal to or larger than second torque which is smaller than the first torque and that the rotation speed of the motor (4) is equal to or less than a second rotation speed which is higher than the first rotation speed is met for a second determination time, and makes the second determination time longer than the first determination time.
