An object of the present invention is to prevent a cost increase and an increase in an installation space due to a redundant arrangement of a vehicle motion control apparatus. A vehicle control apparatus includes an input portion configured to receive an input of a target state from a vehicle motion control controller equipped with a first vehicle motion control function configured to determine the target state for achieving a target route input from an autonomous driving controller, a first control portion configured to control a motion state based on the target state input from the input portion, and a second control portion equipped with a second vehicle motion control function configured to determine the target state for achieving the target route input from the autonomous driving controller and configured to control the motion state based on the target state input from the input portion.

An electric brake comprises a brake mechanism that transmits a thrust generated by driving an electric motor to a piston that moves brake pads pressed against a disc rotor; a thrust sensor that detects the thrust applied to the piston; a rotation angle sensor that detects a rotational position of the electric motor; and a rear electric brake ECU that controls the driving of the electric motor on the basis of a braking command. The rear electric brake ECU detects an abnormality in the brake mechanism from a detected value of the thrust sensor and a detected value of the rotation angle sensor in response to the braking command which are obtained when the electric motor is driven.

A braking system for use with a dual landing gear aircraft. The braking system pairs outboard brake control into an outboard brake system control unit (BSCU) and inboard brake control into a second inboard brake system control unit (BSCU). Each BSCU is designed with two independent control lanes in which the forward wheel set is paired in one control lane and the aft wheels are paired onto the other. Alternate braking is provided via an alternate brake module installed in a fore-aft wheel pairing.

A hydraulic system of a vehicle includes a first pump for supplying at least one first hydraulic circuit and at least one second pump for supplying at least one second hydraulic circuit with hydraulic medium. The second pump supplies the first hydraulic circuit with hydraulic medium in an emergency mode or when an output pressure of the first pump fails.

When an ON operation of an electric parking brake apparatus is performed when a vehicle is moving, a vehicle brake control apparatus executes an EPB stop process in order to stop the vehicle by braking force generated by a hydraulic brake apparatus. If a hydraulic brake malfunction wheel, at which the hydraulic brake apparatus cannot generate braking force properly, is detected during a time period from the beginning of the EPB stop process to the stop of said vehicle, the vehicle brake control apparatus makes the hydraulic brake apparatus stop generating braking force at wheels including the hydraulic brake malfunction wheel. Meanwhile, the vehicle brake control apparatus makes the electric parking brake apparatus start generating braking force at a rear wheel. Subsequently, the vehicle brake control apparatus makes the electric parking brake apparatus start generating braking force to the other rear wheel.

A vehicle braking control apparatus starts to execute a hydraulically moving process to move a hydraulically-moved member toward a brake disc when an emergency braking control is requested to be executed to move the hydraulically-moved member and a mechanically-moved member toward the brake disc to apply braking force to a wheel of a vehicle. The vehicle braking control apparatus starts to execute a mechanically moving process to move the mechanically-moved member toward the brake disc when a predetermined time elapses since starting to execute the hydraulically moving process. The vehicle braking control apparatus stops executing the hydraulically moving process and the mechanically moving process and executes a hydraulically releasing process to move the hydraulically-moved member away from the brake disc and a mechanically releasing process to move the mechanically-moved member away from the brake disc when an execution of the emergency braking control is requested to be stopped.

A brake control system (BCS) may comprise a shutoff valve configured to receive pressurized fluid, a one-way check valve configured to route the pressurized fluid, a first pressure transducer coupled between the one-way check valve and the shutoff valve, and an accumulator configured to supply pressurized fluid to a brake control valve module (BCVM) in response to the shutoff valve being in a closed position.
