BRAKING DEVICE AND BRAKE CONTROL METHOD

WIPO Patent Application WO/2019/017203

A1

Provided is a braking device with which it is possible to increase the precision of hydraulic pressure control. This braking device is provided with: first and second wheel cylinder liquid passages; a hydraulic pressure source; first and second hydraulic pressure sensors; and a control unit. The first wheel cylinder liquid passage is connected to a first wheel cylinder, while the second wheel cylinder liquid passage is connected to a second wheel cylinder. In accordance with the hydraulic pressure of the brake fluid, the first wheel cylinder imparts a braking force to a first wheel, and the second wheel cylinder imparts a braking force to a second wheel. The hydraulic pressure source is capable of supplying the brake fluid to the first wheel cylinder liquid passage and the second wheel cylinder liquid passage. The first hydraulic pressure sensor is capable of detecting the hydraulic pressure in the first wheel cylinder liquid passage, and the second hydraulic pressure sensor is capable of detecting the hydraulic pressure in the second wheel cylinder liquid passage. The control unit is capable of controlling the hydraulic pressure in the first wheel cylinder and the hydraulic pressure in the second wheel cylinder on the basis of detection values of both the first hydraulic pressure sensor and the second hydraulic pressure sensor.
