  • Publication number: 20230091406
    Abstract: A method for lane centering control of a host vehicle that is towing a trailer includes: determining in real time, by a controller of the host vehicle, a radius of curvature of a turn, wherein the host vehicle is approaching the turn; determining, by the controller, a trailer required offset based on the radius of the curvature of the turn to maintain the host vehicle and the trailer in a lane while the host vehicle and the trailer move along the turn; and controlling the host vehicle using the trailer offset to maintain the host vehicle and the trailer in a lane while the host vehicle and the trailer move along the turn. The method also allows the host vehicle to avoid encroaching vehicles.

  • Patent number: 11608089
    Abstract: The present application generally relates to a method and apparatus for controlling an autonomous vehicle. In particular, the method and apparatus are operative for detecting, by a sensor, an object within a first vehicle path, generating, by a processor, a second vehicle path in response to either the detection of the object such that the second vehicle path avoids the object, or a user initiated trajectory shift, generating, by the processor, an initial steering torque in response to the second vehicle path, performing, by the processor, an adaptation on the initial steering torque to generate an adapted steering torque in response to the initial steering torque exceeding a torque rate limit, and controlling, by a vehicle controller a host vehicle steering system to follow the second vehicle signal path in response to the adapted steering torque.

  • Patent number: 11611304
    Abstract: A propulsion system for a device includes an electric motor configured to generate torque to propel the device. The electric motor includes a stator and a rotor with one or more permanent magnets. A controller is in communication with the electric motor and has recorded instructions for a method for minimizing demagnetization in the one or more permanent magnets. The controller is adapted to select a starting point and an intermediate point on a current trajectory in a stator current graph. The controller is adapted to obtain a final point on the stator current trajectory based on a comparison of the intermediate point and a predetermined voltage limit. A demagnetized torque capability is generated based on the final point on the current trajectory.

  • Patent number: 11611305
    Abstract: A method for controlling operation of a rotary electric machine includes receiving, via a bandwidth-partitioning harmonic compensation regulator (HCR) of a controller, a commanded torque and rotational speed of the electric machine, and calculating, via the HCR in response to enabling conditions, a dq harmonic compensation current and a dq harmonic compensation voltage for one or more predetermined harmonic orders using the commanded torque and the rotational speed. The harmonic compensation current and voltage cancel torque ripple and current ripple in the one or more predetermined harmonic orders. The method may include injecting an acoustic tone at a predetermined harmonic order. The method additionally includes adding the dq harmonic compensation current and voltage to a dq current and voltage command, respectively, to generate adjusted dq current and voltage commands. The electric machine is then controlled using the adjusted dq current and voltage commands.
