Abstract
An electronic brake for a vehicle and a control method therefor according to an embodiment of the present disclosure are able to generate a braking force required to safely run the vehicle even if something is wrong with a main brake device, by controlling an auxiliary brake device, which generates a required braking force by serving as a backup for the main brake device.
Claims11
A control method for an electronic brake for a vehicle, the electronic brake comprising a first braking device configured to supply hydraulic pressure to wheel brakes, a second braking device including a pump, that is connected between at least part of the wheel brakes and the first braking device and configured to fluidically disconnect an oil reservoir and an outlet of the pump when a brake pedal is pressed a predetermined distance or greater, and a control unit including a first controller for controlling the first braking device and a second controller for controlling the second braking device,
- the method comprising:
- determining, by the control unit, whether something is wrong with the first braking device;
- based on a determination that something is wrong with the first braking device, determining, by the control unit, whether something is wrong with a blocking valve unit mounted to the second braking device and connected between the oil reservoir and the outlet of the pump;
- and
- based on a determination that something is wrong with the blocking valve unit, controlling the first braking device by the first controller so that a flow path on the first braking device connecting the oil reservoir and the outlet of the pump is closed.
