ABSTRACT:
A braking system for a vehicle is provided. The system includes a hydraulic braking unit that generates a hydraulic braking force and a regenerative braking unit that generates a regenerative braking force regenerating braking energy as regenerative electric power. The system detects a target-braking force required by a driver and controls the hydraulic braking force to the target-braking force. The system controls the regenerative braking force to a first predetermined value while the vehicle is traveling straight. On the other hand, the system controls the regenerative braking force to a second predetermined value, which is smaller than the first predetermined value, while the vehicle is turning.
