Abstract: A tubular member is provided between an inner wall of a hole portion in a fixed member and a shaft. A predetermined gap is provided between an inner wall of the tubular member on a radial inside thereof and the shaft, so that the shaft is rotatable around an axis with respect to the tubular member. On the other hand, the inner wall of the hole portion and the tubular member are fixed to each other. When a load is applied to a predetermined position of a brake pedal, where a driver can apply a pedaling force in a stuck state in which the tubular member and the shaft are stuck together, a torque that releases fixation between the inner wall of the hole portion and the tubular member is greater than 0, and is smaller than a damaging torque that damages at least a part of the brake pedal device.

Abstract: A brake pedal device includes a pedal pad rotatable about an axis when stepped on by a driver, and a reaction force generation mechanism generating a reaction force to the pedal pad according to a stepping amount of the pedal pad. The pedal pad includes a pedal base portion extending away from an axis side end to another end, and a pedal operation portion attached to the pedal base portion and stepped on by the driver. The pedal operation portion protrudes toward a pedal return side in a rotation direction about the axis with respect to the pedal base portion, and a surface of the pedal operation portion has a plane portion that is configured as a flat surface and is stepped on by the driver, so that the reaction force generated by the reaction force generation mechanism acts on the pedal pad in a direction piercing the plane portion.

Abstract: A turbocharger includes a first bypass opening which introduces an exhaust gas from a first exhaust scroll to a downstream area downstream of the turbine impeller, and a second bypass opening which introduces the exhaust gas from a second exhaust scroll to the downstream area. The turbocharger further includes a waste gate valve opens and closes both the first bypass opening and the second bypass opening at the same time. Thus, the waste gate valve can function even though the switch valve is completely closed. Since the exhaust gas is introduced toward the downstream area via both the first bypass opening and the second bypass opening, a pressure loss is restricted and an exhaust pressure of the exhaust gas can be restricted. Further, a turbine efficiency can be improved.
Abstract translation: 涡轮增压器包括将来自第一排气涡轮的废气引导到涡轮机叶轮下游的下游区域的第一旁通开口，以及将来自第二排气涡轮的废气引导到下游区域的第二旁通开口。 涡轮增压器还包括废门阀同时打开和关闭第一旁通开口和第二旁通开口。 因此，即使开关阀完全关闭，废门阀也可起作用。 由于废气通过第一旁通开口和第二旁通开口经由下游区域被引入，所以压力损失受到限制，排气的排气压力受到限制。 此外，可以提高涡轮效率。

Abstract: A pedal device includes: a pedal that is depressed by a driver; and a reaction force generation mechanism. The reaction force generation mechanism generates a reaction force against a depression force applied from the driver to the pedal. The reaction force generation mechanism includes at least one resilient member, a first holder and a second holder. The first holder contacts the at least one resilient member from one side where the pedal is placed in one direction. The second holder contacts the at least one resilient member from another side that is opposite to the one side. One holder among the first holder and the second holder includes an outer guide portion, and another holder among the first holder and the second holder includes an inner guide portion that is fitted into the outer guide portion and is movable relative to the outer guide portion in the one direction.

Abstract: A vehicle pedal module includes a brake pedal device and an accelerator pedal device. The brake pedal device has a brake pedal first housing configured to rotatably support a brake pedal rotating shaft and to cover a brake-pedal reaction force generation mechanism, and a brake pedal second housing configured to support an end portion of the brake-pedal reaction force generation mechanism opposite to the brake pedal. The brake pedal second housing extends from the brake pedal device to the accelerator pedal device, to have at least a part of the accelerator pedal device fixed thereto, and to be installed on a vehicle body.

Abstract: An organ-type pedal device includes a housing, a shaft, a pedal pad, and a sensor unit. The housing is attached to a vehicle body. The shaft is rotatably supported around a center of a shaft receiving portion provided in the housing as a rotation axis. The pedal pad is fixed to the shaft and rotates about a same rotation axis as the shaft. The pedal pad has a structure in which a portion to be stepped on by a driver is arranged above the rotation axis in a vertical direction when being mounted on the vehicle. The sensor unit has a rotating portion provided at the shaft and a signal output portion provided at the housing for outputting a signal corresponding to a phase of the rotating portion, and detects a rotation angle of the pedal pad and the shaft.

Abstract: A brake system includes a brake device, a brake circuit that generates a braking force for braking a vehicle, ECU that controls the braking force generated by the brake circuit according to a stroke amount of the brake pedal, and a user interface. When the first mode is selected, the ECU executes normal control for controlling the braking force generated by the brake circuit based on a basic characteristics which is a basic relationship between the stroke amount of the brake pedal and the braking force. When the second mode is selected, the ECU executes an automatic braking force control when the stroke amount is between a first threshold value and the second threshold value after the stroke amount of the brake pedal increases and reaches a predetermined set value. The ECU executes normal control when the stroke amount of the brake pedal becomes larger than the second threshold value.

Abstract: An arm includes an arm one end and an arm body extended from the arm one end. The arm is coupled with a pedal pad at the arm one end and is coupled with a reaction force generation mechanism on an counter-operation side. A stopper part is a component separate from the pedal pad and fixed to the pedal pad. One part, which is one of the pedal pad and the stopper part, includes a first arrangement section, and the other part, which is the other of the pedal pad and the stopper part, includes a second arrangement section. The first arrangement section and the second arrangement section interpose the arm one end therebetween and hold the arm one end against the pedal pad.
