  • Publication number: 20220289036
    Abstract: A regenerative braking control system for a vehicle can include one or more user interface elements located in a cabin of the vehicle. The one or more user interface elements can correspond to a plurality of regenerative braking settings. Each of the plurality of regenerative braking settings can correspond to a different amount of regenerative braking torque to apply to one or more wheels of the vehicle. The regenerative braking control system can include a processor operatively connected to the user interface elements. The processor can be configured to detect a condition, the condition can be the usage of the plurality of regenerative braking settings by an operator of the vehicle. Responsive to detecting the condition, the processor can be configured to cause the amount of regenerative braking torque for one or more of the plurality of regenerative braking settings to be adjusted based on the condition.

  • Publication number: 20210171334
    Abstract: System, methods, and other embodiments described herein relate to controlling a fuel dispenser. In one embodiment, a method of controlling a fuel dispenser includes broadcasting a pairing signal to a vehicle, receiving, from the vehicle, a confirmation signal confirming completion of a pairing process between the fuel dispenser and the vehicle, transmitting, subsequent to the confirmation signal, a disable signal to the vehicle in response to data from one or more proximity sensors indicating that the vehicle is within a threshold range and a determination that the vehicle is refueling, and transmitting an enable signal to the vehicle in response to a determination that the vehicle is no longer refueling. The disable signal disables a moving capability of the vehicle, and the enable signal restores the moving capability of the vehicle.

  • Patent number: 10793157
    Abstract: A vehicle includes a drivetrain and multiple motors. The drivetrain includes at least one wheel, and is mechanically connected to the motors. The vehicle additionally includes multiple control modules communicatively connected to the motors. The control modules include a power control module per motor. Each power control module is assigned a motor, communicatively connected to the assigned motor, and configured to operate the assigned motor. In response to a traction event, the control modules are configured to switch from a drive mode to a traction control mode. In the drive mode, the power control modules are configured to operate the respective assigned motors to contributorily satisfy at least one propulsion demand global to the vehicle. In the traction control mode, one of the control modules is configured to operate the motors to contributorily satisfy at least one propulsion demand global to the vehicle.

  • Patent number: 10518652
    Abstract: A method of operating a vehicle includes, using a master power control module, and in response to a propulsion demand global to the vehicle, operating a master-assigned motor to which a wheeled drivetrain is mechanically connected to satisfy a share of the propulsion demand. The method additionally includes, using a slave power control module, and in response to the propulsion demand, operating a slave-assigned motor to which the drivetrain is mechanically connected to satisfy a remaining share of the propulsion demand.

  • Patent number: 10088316
    Abstract: Navigation systems and vehicles for predicting routes are provided. A navigation system includes one or more processors, a satellite antenna, one or more memory modules, which stores one or more previous location, a segment list, and machine readable instructions. The satellite antenna receives a first signal from one or more global positioning system satellites. When executed by the one or more processors, the machine readable instructions cause the navigation system to transform the first signal into a first location of the navigation system, access the one or more previous locations stored in the one or more memory modules, automatically determine that a turn has occurred based on the first location and the one or more previous locations, store a segment in the segment list after it is determined that the turn has occurred, and predict a route based on the segment list.
