Abstract: This electric braking device comprises a linear motion conversion mechanism having a screw shaft caused to rotate by an electric motor, and a nut that moves linearly in response to the rotation of the screw shaft. The electric braking device generates braking force in a vehicle wheel due to a piston coupled to the nut moving linearly within a cylinder and applying pressure to brake fluid. In the electric braking device, a coil spring, of which the extending/retracting direction is the linear motion direction of the piston, is installed in such a state as to be sandwiched between the piston and the screw shaft, so as to be compressed in response to the linear movement of the screw shaft in a direction for reducing braking force and to generate repulsive force against the compression.

Abstract: In a vehicle to which a braking control device is applied, the ratio of the rear wheel frictional braking force to the front wheel frictional braking force becomes a prescribed value in a state where the front and rear wheel pressures are equal. An actuator generates front wheel frictional braking force by adjusting front wheel pressure and generates rear wheel frictional braking force by adjusting rear wheel pressure, and a controller that controls the actuator. When the regeneration device can generate the regenerative braking force, the controller individually adjusts the front and rear wheel pressures based on a regenerative braking force so that the ratio of the total rear wheel braking force to the total front wheel braking force becomes a prescribed value. However, when the regeneration device cannot generate the regenerative braking force, the controller adjusts the front wheel pressure and the rear wheel pressure to be equal.

Abstract: An information processing device includes a processor. The processor receives a requested acceleration as one of motion requests for a vehicle from each of sets of application software. The processor performs arbitration of requested accelerations that are received. The processor outputs an instruction signal for controlling an actuator of the vehicle based on a target acceleration that is a result of the arbitration of the requested accelerations. The processor acquires a detection value from an acceleration sensor installed in the vehicle. The processor performs first determination processing to determine whether an external impact has been applied to the vehicle, based on the target acceleration in addition to the detection value.

Abstract: A brake control device includes a processor that controls a brake device of a vehicle. The processor receives a first braking request indicating first braking force by the brake device which is requested from an application that implements a driver assistance function of the vehicle. The processor receives a second braking request indicating second braking force by the brake device which is requested depending on an operation amount of a brake pedal of the vehicle. The processor starts override control when the processor receives the second braking request while the processor controls the brake device in accordance with the first braking request.

Abstract: A braking control device, when stopping a vehicle in a state where a braking force is being applied to the vehicle, executes a reducing control of reducing the braking force corresponding to a braking request before the vehicle stops and executes an increasing control of increasing the braking force corresponding to the braking request before the reducing control in order to suppress vehicle pitching behavior generated when the braking force is applied to the vehicle. The control device sets braking force increase amount in the increasing control based on a difference distance that is a difference between a first distance correlated with a vehicle traveling distance from a reduction start timing when the reducing control is executed until the stopping of the vehicle and a second distance correlated with a vehicle traveling distance from the reduction start timing when the reducing control is not executed until the stopping of the vehicle.
