Document Type and Number:
WIPO Patent Application WO/2020/004347
Kind Code:
A1
Abstract:
This brake control device is applied to a vehicle provided with a regenerative generator on a front wheel, and is configured from an electric pump and first and second pressure adjustment valves. The first pressure adjustment valve is provided in a brake liquid return path including the electric pump, adjusts the brake liquid to a first liquid pressure, and adjusts the rear wheel liquid pressure of a rear wheel cylinder by means of the first liquid pressure. The second pressure adjustment valve is provided in the return path, reduces the first liquid pressure to a second liquid pressure, and adjusts the front wheel liquid pressure of a front wheel cylinder by means of the second liquid pressure. The front wheel flow rate required to increase the front wheel liquid pressure is calculated on the basis of the operation amount of a brake operation member and the regeneration amount of the regenerative generator. The first pressure adjustment valve is controlled on the basis of the front wheel flow rate.
