Abstract: An acceleration device includes: a support portion that has a communication passage, which communicates between a receiving space and an outside; a shaft that is rotatably supported by the support portion; a pedal boss portion that is located on a radially outer side of the shaft and is rotatable integrally with the shaft in the communication passage; a rotational angle sensor that is operable to sense a rotational angle of the shaft relative to the support portion; a pedal spring that urges rotation of the shaft in an accelerator closing direction; and a projection that is formed in a communication passage inner wall, which is an inner wall of the communication passage and is opposed to a boss portion outer wall of the pedal boss portion. The projection projects from the communication passage inner wall in a radially inward direction.

Abstract: A pedal spring urges a pedal spring receiving portion to rotate a manipulation member in an accelerator closing direction. The pedal spring has an end portion that contacts a first contact surface of a front segment. A hysteresis spring urges a hysteresis spring receiving portion, which is engaged with the manipulation member, in the accelerator closing direction. The hysteresis spring has an end portion that contacts a second contact surface of the front segment. A step surface is formed between the first contact surface and the second contact surface to limit movement of the end portion of the hysteresis spring.

Abstract: An accelerator device includes a first cover that provides an internal space for housing a return spring and a failure region where the first cover engages a second cover. The failure region has a thickness configured to be thinner than a thickness of a body of the first cover. When a pedal rotates to open an accelerator, a second cover side friction member creates a force that pushes the second cover toward an outside of the device. The force is relayed to a contact portion of the first cover via a contact portion of the second cover and causes a failure of the failure region. As a result, the return spring is prevented from falling out of the internal space when the body breaks.
Abstract translation: 加速器装置包括第一盖，其提供用于容纳复位弹簧的内部空间和第一盖接合第二盖的故障区域。 故障区域的厚度被配置为比第一盖体的厚度薄。 当踏板旋转以打开加速器时，第二盖侧摩擦构件产生将第二盖朝向装置的外部推动的力。 该力通过第二盖的接触部分中继到第一盖的接触部分，并导致故障区域的故障。 结果，当身体断裂时，防止复位弹簧从内部空间掉出。

Abstract: An accelerator device includes a pedal lever, a reaction force adjuster and a controller. The pedal lever operates according to a stepping operation. The reaction force adjuster is driven by an actuator, and is capable of adjusting a reaction force that is a force in a direction of pushing back the pedal lever. The controller includes a target operation amount setting unit and a drive control unit. The target operation amount setting unit sets a target operation amount, which is an operation amount of the pedal lever according to a vehicle speed. The drive control unit controls a drive of the actuator. The controller controls the reaction force according to the target operation amount so that the operation amount of the pedal lever is within a target range when switching from an automatic drive to a manual drive.

Abstract: An accelerator device includes: a support portion that is installable to a vehicle body; a shaft that is rotatably supported by the support portion; an operable portion that is rotatable integrally with the shaft and is depressible by a driver; an installation blocking portion that is formed in the support portion; and a full opening stopper that limits rotation of the operable portion in an accelerator opening direction when the full opening stopper contacts the operable portion. The installation blocking portion includes a space that opens toward the operable portion. A rib is formed in the space and joins between a top side inner wall and a bottom side inner wall of the space.

Abstract: Each of a cross sectional shape of a contacting portion of a stopper arm and a cross sectional shape of an outer peripheral surface of a pedal shaft is formed in a circular shape, wherein a curvature radius is equal to each other. Each of a cross sectional shape of a stopper surface of a supporting body and a cross sectional shape of an inner peripheral surface of a bearing portion is formed in a circular shape, wherein a curvature radius is equal to each other. A distance between a center of a first virtual circle formed by the contacting portion and a center axis of the pedal shaft is made to be equal to a distance between a center of a second virtual circle formed by the stopper surface and a center axis of the bearing portion. An angle of the stopper arm with respect to the supporting body is not changed, even when the center axis of the pedal shaft is displaced with respect to center axis of the bearing portion.

Abstract: An accelerator pedal is urged in an accelerator closing direction by a hysteresis spring and a return spring. A first increase rate is obtained by dividing an urging force of the hysteresis spring exerted in an accelerator-full-opening position of the accelerator pedal by the urging force of the hysteresis spring exerted in an accelerator-full-closing position of the accelerator pedal. A second increase rate is obtained by dividing an urging force of the return spring exerted in the accelerator-full-opening position of the accelerator pedal by the urging force of the return spring exerted in the accelerator-full-closing position of the accelerator pedal. The second increase rate is smaller than the first increase rate.

Abstract: 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.

Abstract: An accelerator pedal system includes a pedal lever, a lock mechanism, an actuator, and an ECU. The pedal lever operates according to a step-on operation. 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 include a lock operation determination unit and an actuator control unit. The lock operation determination unit determines switching of the lock/unlock operation by the lock mechanism, in response to a voice instruction of a driver. The actuator control unit controls a drive of the actuator according to a determination result of the lock operation determination unit.
