摘要:
In a vehicular braking control apparatus, a target regenerative braking force and a target factional braking force are calculated on the basis of a reference vehicle deceleration Gbt based on an amount of braking operation performed by a driver. Braking forces are usually controlled in a cooperative braking mode realized by regenerative braking and frictional braking (S100 to S210). Braking forces for wheels are controlled in a single braking mode realized by the frictional braking when a braking control is performed for the first time or for the last time in a predetermined number of times, and a correction coefficient (Kp) is calculated as a ratio of a reference vehicle deceleration (Gbt) to an actual vehicle deceleration (Gbx) during the braking control (S90, S220 to S280). The target frictional braking force is corrected by being multiplied by Kp (S190). Hence, a total braking force for the vehicle is prevented from fluctuating when the braking force control mode shifts between the cooperative braking mode and the single braking mode. Thus, the vehicle deceleration is prevented from abruptly changing (S110 to S210).
