This braking control device pumps a brake fluid from a reservoir to each wheel cylinder by one fluid pump and includes an electric motor which drives the fluid pump; and a controller which controls the electric motor. The controller calculates a target fluid pressure on the basis of at least one among the vehicle wheel speed, the vehicle deceleration state, and the turning state of the vehicle, calculates a target discharge amount for the fluid pump on the basis of the target fluid pressure, and controls the electric motor on the basis of the target discharge amount. The controller has a front wheel calculation map of the relationship between the fluid pressure and the inflow volume of the brake fluid corresponding to a front wheel cylinder, and a rear wheel calculation map corresponding to a rear wheel cylinder, and calculates the target discharge amount on the basis of the maps.

A device for an automatic parking brake includes a first microchip and a second microchip. The first microchip and the second microchip are configured to actuate an end stage of the automatic parking brake. The first microchip and the second microchip are configured in a redundant manner with respect to one another in relation to actuating the end stage.

A supported spindle for a device equipped with a spindle nut. The supported spindle includes a spindle body extending along its center longitudinal axis, a support plate, which is welded onto the spindle body in such a way that a weld seam formed between the spindle body and the support plate extends around the center longitudinal axis of the spindle body, and a ring element framing a section of the center longitudinal axis of the spindle body, which contacts the support plate on at least one first contact surface of the ring element and contacts the spindle body on at least one second contact surface of the ring element in such a way that the ring element is clamped between the support plate and the spindle body.

A controller includes a failure detection unit that detects a failure in a first power supply system, and a power supply system control unit that closes a relay in a case where an execution of an automatic parking function starts and, during the execution of the function, causes the first power supply system to supply power, without causing a second power supply system to supply power, to the electric brake device, by setting a target output voltage of the second power supply system lower than an output voltage of the first power supply system when the failure detection unit does not detect the failure, and operates the electric brake device by setting the target output voltage to a voltage within a range in which the electric brake device is operable when the failure detection unit detects the failure.
