Utility vehicle with parallel operated internal combustion engine and electric motor drivetrains

摘要

A utility vehicle includes a first axle, a second axle, an electric motor, an internal combustion engine, and a torque transfer device. The first axle is coupled to first and second wheels. The second axle is coupled to third and fourth wheels. The electric motor drives the first axle in a first direction and a second direction at different times. The internal combustion engine drives a transmission output shaft in one direction. The torque transfer device selectively drives the second axle in the first direction in response to rotation of the transmission output shaft in the one direction. The torque transfer device also selectively drives the second axle in the second direction in response to rotation of the transmission output shaft in the one direction.

1. A utility vehicle comprising:
an internal combustion engine that drives a first set of wheels; an electric motor that drives a second set of wheels, wherein the first and second sets of wheels are different; an accelerator pedal; a position sensor that measures a position of the accelerator pedal; a motor control module that controls the electric motor based on the measured position of the accelerator pedal; a throttle linkage that mechanically connects the accelerator pedal to a throttle valve of the internal combustion engine and that actuates the throttle valve as the accelerator pedal is actuated; a starter/generator unit; a battery pack electrically connected to the starter/generator unit; a first axle structured and operable to drive the first set of wheels; an axle pulley that is attached to the first axle and rotates with the first axle; a starter pulley that is attached to a shaft of the starter/generator unit and rotates with the shaft of the starter/generator unit; and a coupling device structured and operable to drive the starter pulley, starter shaft and starter/generator unit in response to rotation of the first axle and axle pulley generated via torque output by the internal combustion engine such that the starter/generator unit generates electrical power for charging the battery pack.
