摘要： A brake system for a motor vehicle includes separate first and second brake circuits associated to first and second vehicle axles, respectively, and rigidly connected to each other. Hydraulic brake pressure is supplied by a first brake piston of a master cylinder to the first brake circuit and by a second brake piston to the second brake circuit. Operably connected to the first vehicle axle is an electric motor and operates as a recuperator, with a blending device withdrawing hydraulic fluid from the first brake circuit during a recuperation phase of the electric motor. A partition wall between the first and second brake pistons subdivides the master cylinder into a first pressure chamber associated to the first brake piston, and a separate second pressure associated to the second brake piston. A connectable and disconnectable floating piston enables a hydraulic communication between the first and second brake circuits with one another.

摘要： In an emergency stop situation, the regenerative braking system is used to assist in rapid deceleration, by combining regenerative braking with conventional friction brakes. Sensors can also be used to trigger the braking systems, even before the driver is able to react. These sensors might include external cameras, ABS activation detection, radar and ultrasound.

摘要： A regenerative braking system and method are disclosed. According to certain embodiments, the regenerative braking system is engaged and adjusted when the navigation system recognizes that the vehicle is descending down a long grade. This can be pre-stored information, or information derived from prior experience or from the shared experiences of other drivers. The regenerative braking system does not engage to the full stop of the vehicle, but instead can release at approximately three mph and allows friction braking to handle the rest of the stop. The navigation system in this embodiment recognizes that a stop sign or other full-stop situation is present.

摘要： A hybrid ECU reads mode information during regenerative braking, and gradually decreases regenerative braking force when a friction braking force control in accordance with a preparatory mode is started. Thereby, sudden change of deceleration of a vehicle can be prevented. The hybrid ECU 50 makes regenerative braking force disappear immediately when a friction braking force control in accordance with a collision avoidance braking mode is started during regenerative braking. Thereby, the vehicle can be slowed down with a deceleration for collision avoidance.

摘要： A vehicle includes a friction brake, a regenerative brake, and an ECU. The ECU is configured to: (a) control a total braking force that is generated in the vehicle; (b) execute first brake control for controlling a braking force of the vehicle on the basis of the brake operation amount; (c) determine based on the brake operation amount whether the driver's brake operation is being carried out; (d) when the ECU determines that the driver's brake operation is not being carried out, execute second brake control for automatically controlling the braking force of the vehicle in response to a condition of the vehicle, other than the brake operation amount; and (e) when the second brake control is executed, reduce a proportion of a braking force of the regenerative brake within the total braking force as compared to when the first brake control is executed.
