A reaction force imparting device includes an actuator, a power transmission unit, and a lever. The actuator generates a driving force when energized. The power transmission unit has a reduction gear that reduces the speed of the driving force from the actuator, and a shaft member connected to the reduction gear. The lever has one end connected to the shaft member and is rotated by the driving force from the actuator of which the speed is reduced by the reduction gear, and imparts the reaction force to the pedal against a driver's depressing force. The reduction gear and the lever are fastened to both ends of the shaft member by crimping.

The controller of the electric vehicle is configured to control the torque of the electric motor using the MT vehicle model based on the operation amount of the accelerator pedal, the operation amount of the pseudo-clutch pedal, and the shift position of the pseudo-shifter. The electric vehicle also includes a pedal reaction force generator that generates a pedal reaction force in response to the operation of the pseudo-clutch pedal using by the operating of the reaction force actuator. The controller is configured to store the pedal reaction force characteristic simulating the characteristic of the pedal reaction force according to the operation of the clutch pedal. Then, the controller is configured to control the pedal reaction force output by the pedal reaction force generator in response to the operation of the pseudo-clutch pedal using the stored pedal reaction force characteristic.

An accelerator device includes: a pedal lever movable in accordance with a pedaling operation; a drive source configured to generate a drive force when being energized; a power transmission mechanism including an actuator lever that abuts to the pedal lever at a lever abutment point, and configured to transmit the drive force of the drive source to the pedal lever and to apply a reaction force that is a force in a direction opposite to a pedaling direction of the pedal lever; a pedaling amount detector detecting a pedaling amount of the pedal lever; and a controller including a drive force calculator configured to calculate the drive force output from the drive source and to control operation of the drive source. The drive force calculator calculates the drive force corresponding to a target reaction force, based on the pedaling amount.

An actuator generates a drive force in response to energization. A lever is configured to be rotated by a drive force transmitted from the actuator to apply the reaction force to a pedal. A contact member is provided to the lever such that the contact member can be brought into contact with or separated from the pedal. The contact member is made of resin and has: a contact member main body; a contact surface portion that is formed on the contact member main body and is configured to contact the pedal; and a specific shape portion that is shaped in a form of a projection or a recess and is formed on the contact member main body at a time of molding the contact member. The specific shape portion is formed on the contact member main body at a corresponding location that is different from the contact surface portion.

An actuator is provided in an actuator housing. A lever is provided in the actuator housing, rotates by driving force from the actuator, contacts an arm that rotates together with the pedal, and is capable of imparting a reaction force to the pedal against a driver's depression force. A fixing member is formed so that a pedal housing and the actuator housing are fixed apart from each other, and are attachable to a vehicle. A positioning portion determines a contact position between an arm and the lever and between a rotation axis of the pedal and a rotation axis of the lever.

A vehicle includes a vehicle pedal, a vehicle engine and an electronic control unit. The vehicle engine generates a torque output of the vehicle in accordance with an operation of the vehicle pedal. The electronic control unit controls the vehicle pedal between a normal state, an increased resistance state and a decreased resistance state. The vehicle pedal is less sensitive to driver pressure in the increased resistance state. The vehicle pedal is more sensitive to driver pressure in the decreased resistance state.

An accelerator device includes a pedal lever, a drive source, and a power transmission mechanism. The power transmission mechanism has an actuator lever, and applies a reaction force, which is a force in a direction opposite to a depression direction, to the pedal lever via the actuator lever when electricity is applied to the drive source. The actuator lever is rotatable by the driving force of the drive source and abuts against the pedal lever at a lever contact point. A rotation axis of the actuator lever is located between a first straight line which is a line connecting the lever contact point and the pedal rotation fulcrum when the depression angle is a first depression angle, and a second straight line which is a line connecting the lever contact point and the pedal rotation fulcrum when the depression angle is a second depression angle.

An electronic throttle control pedal assembly includes a housing having a friction generating surface, a pedal arm, a spring carrier, and at least one spring. The pedal arm includes a hub portion and a friction generating member. The friction generating member has a lobe connected to a cross member and is positioned on a side surface of the hub portion. The cross member extends within the hub portion. The spring carrier has a friction generating portion. As the pedal arm is depressed, a portion of the spring carrier engages the friction generating portion against the cross member positioned within the hub aperture and pivotally engages a portion of the lobe of the friction generating member against the friction generating surface of the housing thereby creating at least two independent friction generating surfaces to create a hysteresis proportional to the depression of the pedal arm.
