Abstract: PROBLEM TO BE SOLVED: To maximize regenerative efficiency of the whole vehicle while achieving a predetermined front and rear braking force distribution rate. SOLUTION: Target braking forces Fbft, Fbrt for front and rear wheels are computed based on final target deceleration Gt from braking effort of a driver and a predetermined braking force distribution rate for front and rear wheels (S10-60), target regenerative braking force Frgft for front wheel is computed to the lower value of the Fbft and the maximum regenerative braking force Frgfmax, and target regenerative braking Frgrt for rear wheel is computed to the lower value of the Fbrt and the maximum regenerative braking force Frgrmax (S70). The regenerative braking is performed so that the target regenerative braking forces Frgft, Frgrt may be upper limits, and the actual regenerative braking forces Frgfa, Frgra are computed (S210-260). Target friction braking forces Fbpft, Fbprt for front and rear wheels are computed to Fbft-Frgfa, and Fbrt-Frgra respectively (S90), and a friction brake mechanism 42 is controlled so that friction braking forces for front and rear wheels may be the target friction braking force (S100, 110).

Abstract: PROBLEM TO BE SOLVED: To suppress difference between regenerative braking force and hydraulic braking force against a constant master cylinder, in a braking force control device equipped with hydraulic braking means and regenerative braking means. SOLUTION: A hydraulic control mechanism 32 generates hydraulic braking force, and a driving regenerator 14 generates regenerative braking force. The hydraulic braking force is not generated until wheel cylinder pressure PW/ C exceeds idle stroke pressure KPIN. While, the driving regenerator 14 generates the regenerative braking force equal to a required regenerative braking force RBT within a range not exceeding the maximum regenerative braking force. The required regenerative braking force RBT is set to a value equivalent to hydraulic pressure that the idle stroke pressure PIN is subtracted from master cylinder pressure PM/ C.
