BRAKE SYSTEM

摘要

A brake, system includes a hydraulic brake that supplies a hydraulic pressure to a cylinder provided correspondingly to each wheel mounted on a vehicle, thereby pressing friction members against the wheels and applying a hydraulic braking force; an electric brake that is mounted on at least one wheel from among the wheels and applies a braking force to the wheel by drive of an electric actuator; and a controller that executes control of supply of hydraulic pressure to each wheel cylinder by the hydraulic brake and operation control of the electric brake, regardless of a braking request by a driver, and causes a transition from hydraulic braking force control of all of the wheels to hydraulic braking force control of the wheel on which the electric brake has been mounted, when a speed of the vehicle satisfies a condition during the hydraulic braking force control of all of the wheels.

1. A brake system comprising:
a hydraulic brake device that supplies a hydraulic pressure to a wheel cylinder provided correspondingly to each wheel mounted on a vehicle, thereby pressing friction members against the wheels and applying a hydraulic braking force; an electric parking brake device that is mounted on at least one wheel from among the wheels and applies a braking force to the wheel by drive of an electric actuator; and an ECU configured to execute control of supply of hydraulic pressure to each wheel cylinder by the hydraulic brake device and operation control of the electric parking brake device, regardless of a braking request operation performed by a driver, and causes a transition from hydraulic braking force control of all of the wheels to hydraulic braking force control of the wheel on which the electric parking brake device has been mounted, when a speed state of the vehicle satisfies a predetermined speed condition during the hydraulic braking force control of all of the wheels.
