Title:
BRAKE CONTROL DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/221476
Kind Code:
A1
Abstract:
This brake control device pumps a brake fluid from a reservoir to each wheel cylinder by means of one fluid pump to increase the fluid pressure, and is provided with: an electric motor which drives the fluid pump; and a controller which controls the electric motor. The controller calculates a target fluid pressure on the basis of at least one among the vehicle wheel speed, the vehicle deceleration state, and the turning state of the vehicle, calculates a target discharge amount for the fluid pump on the basis of the target fluid pressure, and controls the electric motor on the basis of the target discharge amount. For example, the controller has a front wheel calculation map of the relationship between the fluid pressure and the inflow volume of the brake fluid corresponding to a front wheel cylinder, and a similar rear wheel calculation map corresponding to a rear wheel cylinder, and calculates the target discharge amount on the basis of the front wheel calculation map and the rear wheel calculation map.
