Embodiment Construction

[0015] exist figure 1 According to one embodiment, a system for controlling a vehicle or controlling electrical energy associated with the vehicle includes a first drive motor (26) and a second drive motor (28). The first drive motor and / or the second drive motor are coupled to the wheels of the vehicle in a power mode for propelling the vehicle or in a regenerative braking mode for decelerating the vehicle, regenerative braking refers to the use of the first drive motor and / or the second drive motor, In regenerative braking mode during vehicle motion, a drive motor converts the kinetic energy of the moving vehicle into electrical energy, and the fuel cell (40) provides a load or energy storage device (42) for receiving power from the one or more drive motors generated electrical energy.

[0016] In propulsion mode, the energy storage device ( 42 ), the fuel cell stack ( 54 ) supplies power to one or more drive motors ( 26 , 28 ), and if the drive motors ( 26 , 28 ) use alter...

Abstract

A hybrid power regenerative braking unit can be used for slowing down or stopping a vehicle. For example, the regenerative braking unit can serve as a generator or a traction motor which converts the mechanical energy of wheel rotation into electric energy. In the prior art, a motor vehicle or other diesel-electricity hybrid electric vehicles may dissipate heat energy, wasted by a resistor on a fuel cell power vehicle, of the electric energy generated in this way, and the electric energy generated during regeneration braking from time to time may exceed the available storage capacity of a battery of the vehicle; the price and the weight of the vehicle can be increased obviously when an additional battery is arranged, and therefore it is necessary to improve energy management of the electricity-driven fuel cell vehicle provided with a regenerative brake.

Description

technical field [0001] The present invention relates to a vehicle control system for hybrid regenerative braking. Background technique [0002] A hybrid regenerative braking unit may include a traction motor for slowing or stopping a vehicle, for example, the regenerative braking unit may act as a generator, converting the mechanical energy of wheel rotation into electrical energy, in the prior art, locomotives or other Diesel-electric hybrid vehicles may dissipate the electrical energy so produced in resistance. For fuel cell powered vehicles, the thermal energy wasted by regenerative braking from time to time may exceed the available storage capacity of the vehicle's battery; adding additional batteries can significantly improve this. The price and weight of the vehicle, therefore, need to be upgraded to the energy management of fuel cell vehicles equipped with regenerative braking for electric drive. SUMMARY OF THE INVENTION [0003] A hybrid vehicle control device, ...
