A reaction force control system configured to control a reaction force applied to a pedal without reducing an operational feeling. A controller reduces a reaction force applied to the pedal mildly from a second reaction force to a first reaction force at a rate D upon satisfaction of a predetermined condition. The rate D is determined based on a depression of the pedal, a pedal force applied to the pedal, an elapsed time, or a predetermined function.

An accelerator pedal device according to the present invention is provided with: a pedal arm (30) having an accelerator pedal; a resin housing (10) for supporting the pedal arm such that the pedal arm is swivelable about a prescribed axial line (S) between a rest position and a maximum stepping position; and a return spring (40) that applies a biasing force for returning the pedal arm to the rest position. The housing includes: a boss section (11i) through which a bolt (B) for fixing the housing to a vehicle body is made to pass; and a full open stopper (11n) for specifying the maximum stepping position in the vicinity of the boss section.

An accelerator pedal device of the present invention includes: an accelerator pedal; a hysteresis generation mechanism that generates a hysteresis in pedal effort during a depression operation and a return operation of the accelerator pedal; a reaction force addition mechanism that adds a reaction force in a direction to push back the accelerator pedal; and a control unit that controls the drive of the reaction force addition mechanism in a manner that, with a predetermined target opening degree at which the accelerator pedal is depressed as a boundary, a ratio of change in the pedal effort in an opening degree range above the target opening degree becomes relatively larger than a ratio of change in pedal effort in an opening degree range below the target opening degree.

System, methods, and other embodiments described herein relate to communicating a recommended speed through feedback on a combined pedal for acceleration or braking. In one embodiment, a control system includes a pedal coupled to a first device having a throttle sensor for a vehicle and a first actuator that generates throttle feedback by applying force to the pedal. The control system also includes the pedal being coupled to a second device having a brake activation sensor for the vehicle and a second actuator that generates braking feedback, the first actuator triggers a rotation of the pedal that initiates a braking command through the brake activation sensor according to a recommended speed computed using vehicle data.

An accelerator device includes a case provided on a floor, a pad arranged outside the case to be stepped on by a driver, a pedal arranged in the case to be rotatable in an accelerator opening direction by a stepping force of the pad, an arm connecting the pad to the pedal, and a biasing member configured to bias the pedal in an accelerator closing direction. One end of the arm is press-fitted into a connecting portion of the pad in a press-fitting direction. At least one of the arm or the pad is provided with a play removing part that is configured to eliminate a play between the one end of the arm and the connecting portion in the press-fitting direction by contacting the one end of the arm and the connecting portion.

An integrated control apparatus for driving a vehicle is provided. The apparatus includes a lever housing mounted in an interior space of the vehicle; a joystick lever coupled to the lever housing and configured to be rotatable in a forward-backward direction and a leftward-rightward direction; and a gentle acceleration lever coupled to the joystick lever and configured to be rotatable in the forward-backward direction. When the gentle acceleration lever is operated, a gentle acceleration signal of the vehicle is generated, and when the joystick lever is operated, one of a sudden acceleration signal, a deceleration signal, a steering signal, or a braking signal of the vehicle is generated.

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 shift reaction force generator that generates a shift reaction force in response to the operation of the pseudo-shifter using by the operating of the reaction force actuator. The controller is configured to store the shift reaction force characteristic simulating the characteristic of the shift reaction force according to the operation of the shifter. Then, the controller is configured to control the shift reaction force output by the shift reaction force generator according to the operation of the pseudo-shifter using the stored shift reaction force characteristic.

An accelerator pedal system includes a pedal lever that performs an operation in accordance with a step-on operation, a lock mechanism configured to restrict the operation of the pedal lever, and 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 not restricted by the lock mechanism. A controller includes a locking operation determination unit that determines switching of a locking operation by the lock mechanism, an actuator control unit that controls a driving operation of the actuator, and an information acquisition unit that acquires vehicle speed information. The locking operation determination unit locks the pedal lever when a vehicle is traveling in an automatic driving mode and when a vehicle speed is equal to or more than an activation-determination lower limit value.

A vehicle control system configured to reduce physical stress on a driver to operate an accelerator pedal without reducing acceleration feel. The vehicle control system selects a first driving force property if an estimated stress on an ankle is less than a threshold value, and selects a second driving force property if the estimated stress on the ankle is greater than the threshold value to reduce the stress on the ankle. When the second driving force property is selected, a target driving force is reduced less than a target driving force calculated based on the first driving force property. In this case, the vehicle control system reduces a difference between: a ratio of acceleration to a pedal force given that the first driving force property is selected; and a ratio of acceleration to the pedal force given that the second driving force property is selected.

An adjustable throttle pedal assembly comprises a depressible throttle pedal, biased away from the depressed position, towards a rest position, and an electro-magnetic brake, operable to adjust the force required to depress the throttle pedal. The electro magnetic brake can provide an increased force so as to act as a “virtual footrest”, a “virtual kick-down switch”, or an “ICE force-indent”. providing an increased force at the point which the vehicle will need to start the internal combustion engine (ICE). Moreover, the electromagnetic brake is adjustable to provide different customisable “pedal-weight” settings, to suit a driver's preferred force feedback. For example, discrete pedal weight settings, may be selectable, with a greater retarding force provided by the electromagnetic brake to provide a firmer weight, or the pedal weight can be customisable and calibrated to a given driver.
