Abstract

An accelerator pedal system includes a pedal lever, a lock mechanism, an actuator, and an ECU. The lock mechanism can restrict the operation of the pedal lever. The actuator switches between a locked state in which the operation of the pedal lever is restricted by the lock mechanism and an unlocked state in which the operation of the pedal lever is not restricted. The ECU includes a lock operation determination unit and an actuator control unit. The lock operation determination unit resumes the locked state by the drive of the actuator after a release from the locked state due to the step-on operation of the pedal lever during the automatic drive control in the locked state, when (i) the automatic drive control is continued or (ii) a resuming of the automatic drive control is detected.

Claims3

Dependent claims

An accelerator pedal system comprising:

a pedal lever configured to be operable in accordance with a step-on operation;
a lock mechanism configured to be capable of restricting the operation of the pedal lever;
an actuator configured to switch between a locked state in which the operation of the pedal lever is restricted by the lock mechanism and an unlocked state in which the operation of the pedal lever is free from restriction by the lock mechanism;
and
a controller including
a lock operation determination unit configured to determine switching of a lock operation by the lock mechanism, and
an actuator control unit configured to control a drive of the actuator, wherein
the lock operation determination unit resumes the locked state by the drive of the actuator after the locked state is released due to the step-on operation of the pedal lever during an automatic drive control in the locked state, when (i) the automatic drive control is continued or (ii) a resuming of the automatic drive control is detected.
