Title:
VEHICLE BRAKE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/167643
Kind Code:
A1
Abstract:
A brake ECU (110) stores a deceleration (A) of a vehicle body (S31) upon transition from a regeneration brake mode to a coordinated brake mode. The brake ECU (110), upon transition from the coordinated brake mode to the friction brake mode in a state where a brake operation is constantly held, stores a deceleration (B) at the point in time of transition to the friction brake mode (S32 to S37). The brake ECU (110) calculates a deceleration ratio (α) by dividing the deceleration (A) by the deceleration (B), and updates the deceleration ratio (α)(S39). The brake ECU (110) corrects a target fluid pressure (P*) by using the deceleration ratio (α)(P* = P* × α). In this way, variation in deceleration at the time of transition of brake mode can be suppressed.
