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 an 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 includes a lock operation determination unit and an actuator control unit. The lock operation determination unit determines switching of the locked state and the unlocked state by the lock mechanism. The actuator control unit controls a drive of the actuator. The lock operation determination unit releases the locked state of the pedal lever when a driver's intention to accelerate is detected while a vehicle is traveling in the locked state.

Abstract: 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.

Abstract: A flowmeter includes a hollow housing, a first passage, a second passage, a detector, and a flat surface. The housing includes a first side wall and a second side wall and defines an inlet opening and an outlet opening that is defined in the first side wall. The first passage fluidly connects between the inlet opening and the outlet opening. The second passage branches off from the first passage. The detector is disposed in the second passage and configured to detect a flow rate of the target fluid flowing through the second passage. The flat surface is an outer surface of the first side wall and extends between an upstream end of the first side wall and the outlet opening along the main flow direction.

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.

Abstract: An accelerator pedal system includes a pedal lever configured to perform 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 free from restriction by the lock mechanism. In the accelerator pedal system, a controller configured to change an energization amount to the actuator when a disturbance is detected during a vehicle traveling in the locked state. Thus, the lock state can be suitably controlled.

Abstract: A flowmeter is disposed in a passage through which a fluid flows. The flowmeter includes a first passage and a second passage. The first passage defines an opening through which a part of the fluid flows into the flowmeter from the passage. The second passage branches off from the first passage and includes a flow rate detector configured to detect a flow rate of the fluid flowing through the second passage from the first passage. The second passage has one end at which the second passage branches off from the first passage and the other end. The second passage includes at least one end opening at the other end and an inflow reducer configured to restrict the fluid from flowing into the second passage through the at least one end opening.

Abstract: A brake pedal is operated by a pedal force of a driver. A sensor is capable of detecting a stroke amount of the brake pedal. A brake circuit generates braking force to apply a brake to a vehicle by applying hydraulic pressure to wheel cylinders provided to respective wheels. An electronic control device controls the braking force generated by the brake circuit based on an output signal from the sensor and a state of the vehicle. The electronic control device executes predetermined braking force control under which the braking force generated by the brake circuit is set to be predetermined braking force, when the stroke amount of the brake pedal is between a first threshold and a second threshold larger than the first threshold.
