    Abstract: A vehicle includes an electric machine, a traction battery, a low-voltage power system, a DC to DC converter, and a controller. The electric machine is configured to accelerate the vehicle and to slow the vehicle. The traction battery is configured to deliver electrical power to the electric machine and to receive electrical power from the electric machine via a high-voltage bus. The low-voltage power system has vehicle accessories, an accessory battery, and a low-voltage bus. The DC to DC converter is configured to transfer electrical power between the high-voltage bus and the low-voltage bus. The accessory battery is configured to deliver electrical power to the vehicle accessories and to receive or deliver power from or to DC to DC converter via the low-voltage bus. The controller is configured to controller the transfer of electrical power between the high-voltage bus and the low-voltage bus.

    Abstract: A system includes a virtual-driver module, a DC/DC converter electrically coupled to the virtual-driver module, a low-voltage battery electrically coupled to the virtual-driver module, a high-voltage battery electrically coupled to the DC/DC converter, and a computer communicatively coupled to the DC/DC converter. The computer is programmed to, in response to a request to start a vehicle including the virtual-driver module in a manual mode, the vehicle being in an off state at the time of the request, set a setpoint of the DC/DC converter at a first voltage; then perform at least one pre-drive test on the vehicle; and then set the setpoint of the DC/DC converter at a second voltage lower than the first voltage.

    Abstract: A hybrid electric vehicle having one or more controllers, at least two independently driven electric machines (EMs) that are each coupled to separate drive wheels, and controllers configured to generate a torque split ratio responsive to lateral acceleration and/or unequal friction coefficients detected during braking, and to generate electric power with the motors by regeneratively braking each wheel with unequal torques adjusted by the ratio, such that combined wheel braking torques do not exceed a total braking torque limit for the vehicle. In some configurations, the controller(s) generate the torque split ratio by a predetermined lookup table that maps a plurality of torque split ratios to lateral accelerations, the coefficients, and other parameters. Further arrangements include the controller(s) coupled with sensors that detect wheel slip and yaw rate, and responsive to a braking signal, the controller(s) disengage regenerative braking when the wheel slip and/or vehicle yaw are detected.

    Abstract: An autonomous vehicle controller includes a memory and a processor programmed to execute instructions stored in the memory. The instructions include determining a plurality of energy cost functions. Each energy cost function is associated with a combination of candidate variables. The instructions further include selecting one of the plurality of energy cost functions as a minimum energy cost function, determining a combination of candidate variables associated with the minimum energy cost function, and controlling acceleration of a host vehicle according to the combination of candidate variables associated with the minimum energy cost function.
