  • Patent number: 11845416
    Abstract: A control system for a vehicle has a powertrain system that includes electric power propulsion system and a second propulsion system, a geographical position sensing system, a geographic map database, and a controller. The controller monitors a geographic location of the vehicle determine the geographic location of the vehicle in relation to a first predefined region and a first user-identified region. The powertrain system is controlled to generate propulsion power employing only the electric power propulsion system when the geographic location of the vehicle is within the first predefined region and when the geographic location of the vehicle is within the first user-identified region. The powertrain system is controlled to generate propulsion power employing the second propulsion system when the geographic location of the vehicle is outside the first predefined region and outside the first user-identified region.

  • Publication number: 20220371591
    Abstract: A method of controlling operation of a vehicle includes monitoring at least one of a location and a route of the vehicle when the vehicle is in a first operating state, receiving map data related to an area around at least one of the location and the route, and identifying, based on the map data, one or more map attributes indicative of one or more features of the area. The method also includes comparing the one or more map attributes to at least one reference attribute, and based on the one or more map attributes matching the at least one reference attribute, causing the vehicle to enter a second operating state when the vehicle is in the area.

  • Publication number: 20200039503
    Abstract: A method of controlling a change in net axle torque on a vehicle comprises receiving a request for a desired net axle torque that is different than a current net axle torque, determining whether a lash zone exists between the current net axle torque and the desired net axle torque, determining a progression of constant rates of change of the front axle torque and a progression of constant rates of change of the rear axle torque that will result in a constant rate of change of the net axle torque from the current net axle torque to the desired net axle torque, and commanding the progression of constant rates of change of the front axle torque and the progression of constant rates of change of the rear axle torque if the lash zone exists between the current net axle torque and the desired net axle torque.
