A vehicle theft deterrent apparatus includes a driver verifier, a steering torque detector, an actuator, and a steering controller. The steering torque detector is configured to detect steering torque input by a driver to a steering system. The actuator is configured to generate drive torque to be given to the steering system. The driver verifier is configured to verify whether driver information obtained from the driver matches registered information registered in advance. The steering controller is configured to control the drive torque generated by the actuator based on the steering torque. In a case where the driver verifier determines that the driver information does not match the registered information, the steering controller is configured to permit the driver to steer until a vehicle drives a set distance, and then to cause the actuator to generate the drive torque prohibiting the driver from steering.

The motional state detector is configured to detect a motional state of the vehicle. The minor collision determiner is configured to determine, based on an output from the motional state detector, that a minor collision occurs that is a collision not detected by the collision detector. The braking controller is configured to cause the braking device to generate the braking force if the collision detector does not detect the collision and the minor collision determiner determines that the minor collision occurs.

A vehicle control apparatus includes a braking controller individually controlling braking forces of braking devices for left and right front and rear wheels, a side collision detector detecting a side collision against a vehicle, and a yaw behavior detector detecting yaw behavior of a vehicle body. If the yaw behavior detected after the side collision is such that a rear of the vehicle body shifts away from a collision side relative to a front thereof, the braking controller executes yaw amplification control to cause the braking device for the collision-side front wheel to generate a braking force larger than the remaining wheels. If the detected yaw behavior is such that the front shifts away from the collision side relative to the rear, the braking controller executes the yaw amplification control to cause the braking device for the collision-side rear wheel to generate a braking force larger than the remaining wheels.
