Abstract: In a braking control device, a controller is configured to determine an inside and an outside of a turn by using the yaw rate, to calculate a deflection index based on a standard turning amount corresponding to a steering angle and an actual turning amount corresponding to a yaw rate, to reduce the braking torque of the rear wheel on the outside of the vehicle turn based on the deflection index when an excessive deceleration slip of the rear wheel on the inside of the vehicle turn is inhibited during an execution of anti-skid control.

Abstract: A brake device includes: a first pressurizing unit configured to increase a WC pressure by supplying brake fluid into wheel cylinders provided in wheels RL and RR; a second pressurizing unit connected to a reservoir tank via a fourth flow passage and configured to increase the WC pressure by supplying the brake fluid taken in from the reservoir tank into the wheel cylinders; and a brake control unit configured to control at least one of the first pressurizing unit and the second pressurizing unit based on a target WC pressure. The brake control unit is configured to, when the WC pressure is to be increased by operating the second pressurizing unit, execute an auxiliary brake control in which the first pressurizing unit is operated to assist the second pressurizing unit to increase the WC pressure.

Abstract: A braking control device is applied to, for example, a vehicle in which a regenerative braking force is generated on a front wheel by a regenerative generator provided on the front wheel. The braking control device includes an actuator configured to individually generate a front wheel friction braking force on the front wheel and a rear wheel friction braking force Fmr on a rear wheel of the vehicle; and a braking controller configured to control the actuator. In the braking control device, the braking controller is configured to regulate the front and rear wheel friction braking forces based on a normative regenerative force corresponding to a rotation speed equivalent value equivalent to a rotation speed of the regenerative generator.

Abstract: A travel control device includes a turning control unit configured to execute turning support control causing a turning state quantity to follow a target turning state quantity by causing at least one of a front wheel steered angle adjustment device, a rear wheel steered angle adjustment device, and a braking device to be driven, and a steering instruction unit configured to, when steering is not being performed during the execution of turning support control, derive a holding torque and instruct a steering device to apply the holding torque to a steering wheel. The turning control unit causes the rear wheel steered angle adjustment device and/or the braking device to be driven but causes the front wheel steered angle adjustment device not to be driven when steering is not being performed. The turning control unit causes the front wheel steered angle adjustment device to be driven when steering is being performed.
