Title:
BRAKING FORCE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3541647
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a braking force control device which can suppress deterioration of brake feeling, which may be caused by malfunction of following-up of actual fluid pressure braking force with variation of regenerative braking force.
SOLUTION: A motor ECU 15 and a regenerative ECU 17 compute required regenerative braking torque(REBTB) equivalent to master cylinder pressure, and also compute actual regenerative braking torque (DEBT) applied to a motor 11. When the value of REBTB is not more than the sum of the value DEBT and a limit value 20 Nm, an inverter 13 is so controlled that the braking force of REBTB is applied. When the value REBTB exceeds the sum of the value DEBT and the limit value 20 Nm, the value REBTB is so renewed as to be equal to the sum of the value DEBT and the limit value 20 Nm. The inverter 13 is so controlled that the braking force of REBTB equal to the sum is applied.
