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 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: 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: A rotation angle sensor detects a rotation angle of a pedal by its first Hall IC and second Hall IC, which are disposed between two magnets and output voltages varying with magnetic flux changes. When the rotation angle of the pedal is an accelerator full-closure rotation angle or more, the first Hall IC generates a first voltage V1, which is twice as large as a second voltage V2 of the second Hall IC. When the rotation angle is less than 0°, the first Hall IC fixes the first voltage irrespective of the rotation angle. An ECU determines that the rotation angle is abnormal indicating that the pedal rotates in an accelerator closing direction beyond an accelerator full-closure position, when an output difference G1 calculated as G1=V1/2−V2 is more than a predetermined value.
Abstract translation: 旋转角度传感器通过其设置在两个磁体之间的第一霍尔IC和第二霍尔IC检测踏板的旋转角度，并且随着磁通量变化而变化的输出电压。 当踏板的旋转角度为加速器全闭合旋转角度以上时，第一霍尔IC产生的第一电压V1为第二霍尔IC的第二电压V2的两倍。 当旋转角度小于0°时，第一霍尔IC固定第一电压，而与旋转角度无关。 当以G1 = V1 / 2-V2计算的输出差G1大于预定值时，ECU确定旋转角度异常，指示踏板在加速器闭合方向超过加速器全闭合位置时旋转。

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.
