A fluid drive system that can be used to drive a vehicle and has energy regeneration and storage capabilities. The fluid drive system includes an electrical energy supply source mounted on the vehicle, at least one electrical motor electrically connected to the electrical supply source, and a hydraulic pump driven that may be of the variable displacement type by the electrical motor. The fluid drive system may also include a low pressure hydraulic fluid supply tank supplying fluid to the hydraulic pump, at least one pneumatically charged accumulator tank for storing pressurized hydraulic fluid, a combination hydraulic motor and pump that may also be of the variable displacement type being alternately driven by the hydraulic pump and the pneumatically charged accumulator tank; and an electrical regeneration system for regenerating the electrical energy supply. The electrical regeneration system may be powered by hydraulic fluid from the combination electrical motor and pump. The combination hydraulic motor and pump propels the vehicle during acceleration and speed maintaining operations and may also serves as a braking mechanism during deceleration of the vehicle. The combination hydraulic motor and pump may also pump hydraulic fluid into the pneumatically charged accumulator tank during at least a portion of the time that the vehicle is decelerating. The combination hydraulic motor and pump may further pump hydraulic fluid for powering the electrical regeneration system when the pneumatically charged accumulator tank is fully pressurized. The electrical regeneration system also has the ability to recharge the electrical energy supply while the vehicle is stopped using stored recovered kinetic energy.

An energy converting brake system 10 comprises a brake 12 comprising a cooling circuit 18 through which a brake cooling fluid flows. The cooling fluid is passed through heat exchanger 22 which also includes a thermoelectric conversion device 26. Heat from the cooling fluid is dissipated in the heat exchanger 22 through the thermoelectric conversion device 26, which in turn generates an electric current. The electric current can be stored in a storage device 28.

A vehicle brake system 10 is provided which compensates for brake pedal feel variation to provide enhanced braking feel. The brake system 10 includes a brake pedal 18, a wheel speed sensor 20, and a database 16 for storing target accelerations and torque to pressure parameters. The brake system 10 may employ a friction brakes 26 and regenerative brakes 29. The brake system further includes a controller 12 for controlling the amount of braking, including the friction brake actuator 24. The controller 12 determines brake acceleration caused by braking torque and determines a target acceleration based on the driver commanded input. The controller 12 also determines a brake acceleration error as the difference between the target acceleration and the brake acceleration. The controller adjusts the torque-related parameter to reduce the brake acceleration error by adjusting the braking torque generated by the friction brake actuator to compensate for brake torque variation.
