Title:
VEHICULAR BRAKE DEVICE
Document Type and Number:
Japanese Patent JP2017154721
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular brake device capable of increasing a ratio of regenerative brake force.SOLUTION: A vehicular brake device comprises: a first valve part 44 for adjusting first differential pressure which is differential pressure between fluid pressure on a master cylinder 1 side and fluid pressure on a wheel cylinder WC side; a storage part 45 for forming a storage chamber 45a for storing a fluid; second valve parts 461, 462 for adjusting second differential pressure which is differential pressure between fluid pressure on the master cylinder 1 side and fluid pressure on the storage chamber 45a side; an electric pump 47 for discharging the fluid in the storage chamber 45a to a part on the wheel cylinder WC side relative to the first valve part 44 of the first fluid pressure circuit 41; and a control part 63 for actuating the electric pump 47, controlling the first valve part 44 so that the first differential pressure does not become 0, and controlling the second valve parts 461, 462 so that the second differential pressure does not become 0, in a period since application of brake force to wheels W is started, until a request value acquired by a request brake force acquisition part 61 reaches a maximum value acquired by a maximum regenerative brake force acquisition part 62.SELECTED DRAWING: Figure 3
