  • Patent number: 11639110
    Abstract: An electrified drivetrain for a vehicle includes a first electric machine, a second electric machine, a clutch, an HVAC compressor, and a controller. The second electric machine is rotatably coupled to a geartrain, the first electric machine is rotatably coupled to the HVAC compressor, and is rotatably couplable to the geartrain via the clutch, and the clutch is operative in a first state and a second state. The first electric machine is rotatably coupled to the geartrain when the clutch is controlled to the first state, and is decoupled from the geartrain when the clutch is controlled to the second state. The controller is operatively connected to the first and second electric machines, the clutch, and the HVAC compressor to control operation of the electrified drivetrain. The first electric machine can be used as a heater element and to provide mechanical power to the drivetrain.

  • Publication number: 20230126666
    Abstract: A method of maintaining stability of a motor vehicle having a first axle, a second axle, and a steering actuator configured to steer the first axle includes determining localization and heading of the vehicle. The method also includes determining a current side-slip angle of the second axle and setting a maximum side-slip angle of the second axle using the friction coefficient at the vehicle and road surface interface. The method additionally includes predicting when the maximum side-slip angle would be exceeded using the localization, heading, and determined current side-slip angle as inputs to a linear computational model. The method also includes updating the model using the prediction of when the maximum side-slip angle would be exceeded to determine impending instability of the vehicle. Furthermore, the method includes correcting for the impending instability using the updated model and the maximum side-slip angle via modifying a steering angle of the first axle.

  • Publication number: 20230125809
    Abstract: An electronic pallet (e-pallet) includes a superstructure mounted to a wheeled base platform. A tether device defines an articulation angle with respect to a leading edge of the superstructure, and is grasped by an operator towing the e-pallet. A motor connected to driven road wheels transmits a drive torque to the road wheels responsive to motor control signals, including a desired yaw rate and ground speed. A speed sensor, angle sensor, and length sensor are respectively configured to determine an actual ground speed of the e-pallet, the articulation angle, and a length of the tether device. An electronic controller, in response to the input signals, generates the motor control signals using proportional-integral-derivative (PID) control logic. Coupled lateral and longitudinal dynamics control loops respectively determine the desired yaw rate and ground speed to accommodate for motion of the operator.
