Abstract
A hybrid system comprises a vehicle having a power take-off (PTO) and a controller (e.g., electronic control module/unit (ECM/U)) configured to: (1) control the on/off state of the ICE, (2) control rotation of the ICE through a clutch actuator or automatic transmission controller, and (3) control the on/off state of an electric motor, the electric motor coupled to the PTO to drive a transmission of the vehicle, thereby moving the vehicle independent of the state of the ICE. The hybrid system may allow the vehicle to move via the ICE, electric motor, or combination of the two.
Claims17
A hybrid system for a vehicle, comprising:
- a drive system, comprising:
- an electric motor, and
- at least one battery;
- an electronic control module;
- wherein, the electric motor is configured to be coupled to a power takeoff of the vehicle;
- and
- wherein the electronic control module is configured to control an on/off status of the electric motor, an operational status of an internal combustion engine, and the operational status of the power takeoff.
A hybrid system for a vehicle, comprising:
- a drive system, comprising:
- an electric motor,
- at least one battery, and
- a battery management system;
- an electronic control module coupled to the drive system;
- a control interface;
- and
- a gearbox interposed between the electric motor and a power takeoff, the power takeoff coupled to a transmission of the vehicle;
- wherein the electronic control module is configured to control the on/off status of the electric motor, the operational status of an internal combustion engine of the vehicle, and the operational status of the power takeoff.
A method of using a hybrid system for a vehicle, the method comprising:
- using an electronic control module to monitor a torque demand, an operational status of an internal combustion engine, and a status of one or more sensors;
- using an electric motor to selectively drive a power takeoff;
- and
- using the electronic control module to:
- i. control an on/off status of the electric motor, the electric motor coupled to the power takeoff of the vehicle,
- ii. engage or disengage a clutch or a torque converter,
- iii. apply torque or negative torque to a transmission via the electric motor,
- iv. control the operational status of the internal combustion engine, and
- v. control a throttle of the vehicle.
