Abstract: A vehicle includes a regenerative generator on a front wheel. A braking control device includes an actuator that applies a front wheel torque and a rear wheel torque, and a controller that individually adjusts the front wheel torque and the rear wheel torque. The controller is configured to determine the front wheel torque and the rear wheel torque to zero when a regenerative braking force Fg generated by the regenerative generator has not reached a maximum regenerative force Fx which is a generatable maximum value. On the other hand, the controller is configured to increase the rear wheel torque from zero before increasing the front wheel torque from zero when the regenerative braking force Fg reaches the maximum regenerative force Fx.

Abstract: A braking control device includes a first adjustment unit, a master unit, a regenerative coordination unit, a first opening/closing valve, a second opening/closing valve, a reaction force hydraulic pressure sensor, an input hydraulic pressure sensor, a controller. The master unit includes a master cylinder and a master piston, a master chamber, a servo chamber, and a reaction force chamber. The regenerative coordination unit includes an input piston. The first opening/closing valve provided in a first fluid passage. The second opening/closing valve provided in a second fluid passage. The reaction force hydraulic pressure sensor detects a pressure in the reaction force chamber. The input hydraulic pressure sensor detects a pressure in the input cylinder. The controller determines, based on the reaction force hydraulic pressure and the input hydraulic pressure, suitability of at least one of the master unit, the regenerative coordination unit, the first opening/closing valve, and the second opening/closing valve.

Abstract: A braking control device includes a front wheel motor that controls a front wheel hydraulic pressure to adjust a front wheel braking torque, a first motor that adjusts a right rear wheel braking torque, and a second motor that adjusts a left rear wheel braking torque. The front wheel motor includes two-system coils, and the first and second motors include one-system coils. A controller that controls the electric motors includes a one-side drive circuit that energizes one of the two-system coils of the front wheel motor, an other-side front wheel drive circuit that energizes the other of the two-system coils of the front wheel motor, a first rear wheel drive circuit that energizes the one-system coil of the first motor, and a second rear wheel drive circuit that energizes the one-system coil of the second motor.

Abstract: This electric braking device uses drive torque of an electric motor to push a friction member against a rotating member secured to a vehicle wheel and produce braking torque in the vehicle wheel. This device comprises a body power source for electric motor power supply secured to a body of the vehicle, and a vehicle wheel power source for electric motor power supply secured to the vehicle wheel. The body power source supplies power to the vehicle wheel power source via a first electric path, and the vehicle wheel power source supplies power to the electric motor via a second electric path. When braking torque is produced in the vehicle wheel, the electric motor is normally driven using the vehicle wheel power source. An electric braking device is thereby provided in which a power line electrically connecting the body side and the vehicle wheel side bends readily.

Abstract: A mount member is fixed to a support member by first and second fastening members, and a caliper is mounted to the mount member by first and second guide members. A motor axis of an electric motor and an axis of a shaft member configured to press a pressing member are different from each other. The electric motor is fixed to the caliper. When viewed from an axial direction of the first guide member, the motor axis is positioned inside a fastening quadrangle having four corners corresponding to positions of respective axes of, and is perpendicular to the axis, and the motor axis is orthogonal to a plane of the fastening quadrangle. As a result, there may be provided a vehicle electric braking device in which an axial direction dimension may be reduced to suppress an amplitude caused by vibration, and components sensitive to vibration influence are appropriately arranged.
