PROBLEM TO BE SOLVED: To provide a braking device mounted on a front-wheel driven vehicle and including a regenerative braking device and a liquid pressure braking device by which front and rear liquid pressure braking torques are distributed in accordance with an ideal distribution line, for inhibiting the deterioration of energy efficiency while inhibiting the deteriorating control stability of the vehicle. SOLUTION: This device makes regenerative braking torque smaller when the increasing gradient of slip relative to a front and rear rotating speed difference is greater than when it is smaller. Accordingly, total front and rear braking torque distribution can be approximated to ideal distribution and the deterioration of control stability is inhibited. Since the regenerative braking torque is controlled with the gradient of relative slip, the excessive deterioration of energy efficiency can be inhibited without excessively controlling the regenerative braking torque. |
