Accelerator device

An accelerator device comprising:

• a pedal lever configured to operate in accordance with a stepping operation;
• a reaction force adjuster driven by an actuator and capable of adjusting a reaction force that is a force in a direction of pushing back the pedal lever;
• and
• a controller including:
• a target operation amount setting unit configured to set a target operation amount of the pedal lever in accordance with a vehicle speed;
• and
• a drive control unit configured to control a drive of the actuator,
• wherein the controller is configured to control the reaction force in accordance with the target operation amount of the pedal lever so as to make an operation amount of the pedal lever to be within a target range, when switching from an automatic drive to a manual drive,
• wherein the controller is configured to control the reaction force adjuster such that the reaction force becomes larger when the operation amount of the pedal lever reaches the target range, than that before reaching the target range, and
• when the pedal lever stays for a predetermined time in a state in which the operation amount of the pedal lever is less than the target range, the controller controls the reaction force adjuster to reduce the reaction force.

An accelerator device comprising:

• a pedal lever configured to operate in accordance with a stepping operation;
• a power transmission mechanism driven by an actuator and configured to adjust a reaction force that is a force in a direction of pushing back the pedal lever;
• and
• a controller including at least one processor, and configured
• to set a target operation amount of the pedal lever in accordance with a vehicle speed,
• to control the reaction force by controlling an operation of the actuator, to control an operation amount of the pedal lever to be within a target range by controlling the reaction force in accordance with the target operation amount of the pedal lever, and
• to permit a switching from an automatic drive to a manual drive, when the operation amount of the pedal lever is stabilized within the target range,
• to control the reaction force adjuster such that the reaction force becomes larger when the operation amount of the pedal lever reaches the target range, than that before reaching the target range, and
• to perform a reaction force return control in which the reaction force returns to an initial state by gradually changing the reaction force, when the operation amount of the pedal lever is stabilized within the target range.
