Abstract
One embodiment relates to a hybrid vehicle drive system for a vehicle including a first prime mover, a first prime mover driven transmission, a rechargeable power source, and a PTO. The hybrid vehicle drive system can include a control system for reducing or eliminating regenerative braking during a traction control or anti-lock braking event.
Claims20
A vehicle drive system for a vehicle including a first prime mover, a first prime mover driven transmission, a rechargeable energy source, and a PTO, the vehicle drive system comprising:
- a hydraulic pump;
- and
- an electric motor configured to be in mechanical communication with the PTO and the hydraulic pump and electrical communication with the rechargeable energy source, wherein the electric motor is configured to receive power from the first prime mover driven transmission through the PTO, wherein the hydraulic pump is configured to receive power from the electric motor when the electric motor rotates, the electric motor being configured to use power from the rechargeable power source or from the prime mover driven transmission through the PTO to rotate, wherein electric motor is configured to provide power to the rechargeable energy source when rotated by the prime mover driven transmission through the PTO;
- and
- a control system in electrical communication with the electric motor, the control system being configured to eliminate or reduce regenerative braking in response to an antilock or traction control event.
A method of operating a hybrid vehicle drive system comprising a prime mover, a prime mover driven transmission, an electric motor, a PTO operable to transfer power between the prime mover driven transmission and the electric motor, an energy source operable to provide power to or receive power from the electric motor, the method comprising:
- providing power from the PTO to an electric motor to charge the energy source;
- and
- reducing or eliminating the power provided from the PTO to the electric motor in response to an antilock or traction control event.
A hybrid vehicle drive system for use with a first prime mover and a first transmission driven by the first prime mover, the system comprising:
- an electric motor coupled to a rechargeable energy source;
- a PTO, wherein the first prime mover is configured to provide power through the first transmission to the PTO to operate the electric motor;
- and
- a control system configured to reduce or eliminate charging of the rechargeable energy source during an antilock or traction control event.
