Problems solved by technology

Therefore, from the point of view of a total of four wheels, there may be situations where braking is not possible
In severe cases, when the piston repeatedly and continuously collides with the end at the position of 0 [mm], the pressure forming structure containing the screw may be damaged

Abstract

A braking apparatus of a vehicle including: a brake pedal position detector configured to detect a position of a brake pedal; a piston displacement detector configured to detect a displacement of a piston installed in a main master cylinder; a rear wheel circuit pressure detector configured to detect pressure supplied to a rear wheel circuit; a front wheel circuit pressure detector configured to detect pressure supplied to a front wheel circuit; a motor driver configured to drive a motor to move the piston; and a controller configured to receive the position of the brake pedal, the displacement of the piston, rear wheel circuit pressure and front wheel circuit pressure, determine a fail of a circuit isolation valve, and perform fail safe driving by operating the motor driver and a normal operating valve to supply pressure to only one of the rear wheel circuit and the front wheel circuit.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2019-0000596 filed with the Korean Intellectual Property Office on January 3, 2019, the entire contents of which are hereby incorporated by reference. technical field [0003] Embodiments of the present disclosure relate to a brake device of a vehicle and a control method thereof, and more particularly, to a device capable of detecting the A brake device and a control method of a vehicle for fault-safe driving of a circuit isolation valve to improve brake reliability. Background technique [0004] Generally, the electric power booster brake system maintains most of the brake mechanism of the existing vacuum booster. However, the difference between the electric power brake system and the vacuum booster in the distribution mechanism is that the electric power brake system uses the force of the electric power booster (or electric motor) to distribute ...
