Abstract: An electric braking device generates a braking force at a wheel via application of a pressing force by a piston by linear motion of the piston in response to the transmission of a forward-direction rotational torque from an electric motor to a linear motion conversion mechanism. The electric braking device is provided with a one-way clutch that cuts off the transmission of a rotational torque between the electric motor and the linear motion conversion mechanism when applied with a rotational torque in a direction opposite to the forward direction and having a magnitude equal to or greater than a predetermined value.

Abstract: A braking control device includes: a master cylinder having a master chamber defined by a master piston; and a first pressure regulation unit having a servo chamber located on an opposite side of the master chamber and supplying a servo pressure to the servo chamber to generate a master pressure in the master chamber. The first pressure regulation unit acquires the master pressure and servo pressure and determines bottoming out of the master piston based on a comparison between the master and servo pressures. The first pressure regulation unit may make the comparison based on pressure-receiving area of the servo chamber and a pressure-receiving area of the master chamber. If the servo chamber pressure-receiving area is equal to the master chamber pressure-receiving area, the first pressure regulation unit determines bottoming out occurs when a difference between the servo pressure and the master pressure equals or exceeds a predetermined pressure.

Abstract: A parking brake device includes a fluid unit including: a fluid pump that suctions brake fluid from a master cylinder using a first electric motor; and a pressure regulating valve that increases pressure of the brake fluid discharged by the fluid pump and supplies the increased pressure to a wheel cylinder as a brake fluid pressure, the fluid unit causing the brake fluid pressure to press a friction member against a rotating member fixed to vehicle wheels to generate a braking force, an electrically-powered unit that uses a second electric motor and generates the braking force on a parking wheel on which a parking brake is applied among the vehicle wheels, and a controller that controls the fluid unit and the electrically-powered unit. When the parking brake is actuated, the controller increases only the brake fluid pressure corresponding to the parking wheel in the wheel cylinder.

Abstract: An information processing device includes a processor. The processor acquires an operation amount for acceleration/deceleration of a first vehicle by a driver of the first vehicle. The processor acquires an inter-vehicle distance from the first vehicle to a second vehicle traveling ahead of the first vehicle. The processor determines whether the operation amount meets a first specific condition determined in advance. The processor determines whether the inter-vehicle distance meets a second specific condition determined in advance. The processor calculates a diagnosis result about the inter-vehicle distance based on the inter-vehicle distance acquired when the processor determines that both the first specific condition and the second specific condition are met. The processor outputs the diagnosis result.
