摘要： 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 one or more driving environment conditions. 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.

摘要： A vehicle, a vehicle fuel reactant leak detection system, a computer program product, and a computer implemented method of detecting leakage of a fuel reactant from a vehicle. The vehicle includes one or more fuel cell modules, a fuel supply source to supply a fuel reactant to the one or more fuel cell modules via a high-pressure fuel supply line, a fuel supply valve configured to open and close fuel reactant flow through the high-pressure fuel supply line, and a computing device, operatively connected to the fuel supply source. The computing device includes one or more processors caused to conduct, in response to a detection as sensor data of pressure in the high-pressure fuel supply line when the vehicle engine is in a non-operating state, fuel pressure analysis of the sensor data, and detect, based on the fuel pressure analysis, leakage of the fuel reactant at the fuel supply valve.

摘要： A system for managing storage of electrical energy can include an electromagnetic machine and a controller. The electromagnetic machine can have a rotor and a stator. The rotor can be configured to be connected to a shaft. One of the rotor or the stator can have first windings and second windings. The controller can be configured to control first circuitry and second circuitry. The first circuitry can be configured to cause energy to flow from a first energy storage device to the first windings to cause the shaft to rotate. The second circuitry can be configured to cause energy to flow selectively: (1) from a second energy storage device to the second windings to cause the shaft to rotate or (2) from the second windings to the second energy storage device to cause the second energy storage device to be charged.

摘要： 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.

摘要： A powertrain for an electric vehicle has a driveshaft connected to two or more motors where each motor is connected to a battery pack associated with that motor. A controller is used to select one or more motors to be energized for propulsion or used for regenerative braking to recharge the battery pack to which it is coupled. The controller can optimize the state of charge (SOC) difference of the battery packs and provide for a smooth and efficient powering of the vehicle for acceleration and climbing and optimize the range of the vehicle by management of the relative SOC of the battery packs. The electric vehicle can include two or more fuel cells that individually coupled to a motor.
