Abstract
A headrest control apparatus has a rear radar sensor, a PCS-ECU, a headrest drive mechanism that supports a headrest and drives the headrest relative to the vehicle in its longitudinal direction, a motor, a capacitance sensor, and a headrest control portion that controls the motor. The headrest control portion executes a forward drive control in which the headrest starts to be driven forward in response to a start-up signal from the PCS-ECU and the motor is stopped in response to the positional relation between the occupant's head and the headrest reaching a predetermined positional relation. After the forward drive control, the headrest control portion executes a hold control in which the motor is held in a stopped state for a predetermined hold time. After the hold control, the headrest control portion executes a backward drive control in which the headrest is driven backward.
