摘要： 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.

摘要： 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.

摘要： 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.

摘要： A braking control device includes: a control unit that is configured to control front-wheel braking power and rear-wheel braking power based on braking power distribution and requested braking power; a distribution setting unit that is configured to set the braking power distribution; and a slip judgment unit that is configured to judge whether or not the vehicle is in a rear-wheel-led slip state. If it is judged that the vehicle is in the rear-wheel-led slip state when the braking power distribution is first braking power distribution, the distribution setting unit executes a distribution shifting process of shifting the braking power distribution to second braking power distribution within a predetermined period. The second braking power distribution is such distribution that the rear-wheel braking power is reduced relative to that observed when the first braking power distribution is set as the braking power distribution.
