摘要： A battery assembly including a housing having a first coolant port and a second coolant port includes a valve assembly fluidically connected to one of the first coolant port and the second coolant port, a pump fluidically connected to the valve assembly and the battery assembly, and a coolant controller operatively connected to the pump and the valve assembly. The coolant controller is operable to control the valve assembly to pass a flow of coolant into the one of the first coolant port and the second coolant port for a first time period and to pass the flow of coolant into the other of the first coolant port and the second coolant port for a second time period.

摘要： A fluid-cooled axial flux motor having a stator, a rotor disposed adjacent to the stator, and a rotor shaft rotationally fixed onto the rotor. The rotor shaft includes axial coolant passageway having an inlet and opposite outlet. The rotor includes coolant passageways extending radially from rotor shaft. The rotor coolant passageways include an inlet in fluid communication with the outlet of the axial coolant passageway and an outlet. The fluid-cooled axial flux motor further includes a coolant distribution header having an inlet in fluid communication with the outlet of the rotor coolant passageway, a coolant collection header having an inlet in fluid communication with the outlet of the coolant distribution header, and a collection header outlet. The outlet of the coolant distribution header is disposed above the stator and the inlet of the coolant collection header is disposed below the stator with respect to the direction of gravity.

摘要： Systems and methods are provided for locking a cycle. A clutch system of the cycle includes a forward lock system configured to alternatively prevent or allow operation of the cycle in a forward direction. A shaft extends through the clutch system. An actuator is configured to move the forward lock system along the shaft between a lock position and a free position. A controller is configured to shift the actuator, via a signal from a processor, between the lock position and the free position. The cycle is configured to be locked against forward operation by the clutch system.

摘要： Systems, automobiles, and methods are provided for warning of a potential collision between an approaching object and an opened side door of a vehicle. A system for a vehicle includes an approach sensor, a side door sensor, an alarm, and a controller. The approach sensor is configured to attach to the vehicle and to generate approach sensor data indicating an approaching object that may collide with a side door of the vehicle. The side door sensor is configured to generate door sensor data indicating an impending opening of the side door by an occupant. The alarm is configured to communicate with the occupant. The controller includes an alert initiation module configured to alert the occupant that the approaching object may collide with the side door in response to detecting the impending opening of the side door and detecting the approaching object.

摘要： Systems and methods are provided for controlling a shared machine. The shared machine includes a mechanism that allows for an operational function of the shared machine to be controlled via a control system. A server system can process location information that indicates a location of the shared machine to determine whether the location corresponds to a non-permitted area. When the location corresponds to a non-permitted area, a command is generated to automatically place the mechanism in a first state so that the operational function of the shared machine is prevented from being enabled while the shared machine remains in the non-permitted area.

摘要： A powertrain includes an internal combustion engine, an electric machine including a rotor, a geartrain including a pump drive mechanism, a first clutch and a second clutch and a variator for a continuously variable transmission (CVT). The internal combustion engine is rotatably coupled to the rotor of the electric machine by activation of a second clutch. The internal combustion engine is rotatably coupled to the variator by activation of first and second clutches. The rotor of the electric machine is rotatably coupled to the variator by activation of the first clutch, and the electric machine is operative in either a forward direction or a reverse direction. The geartrain is disposed to operate the pump drive mechanism to drive a fluidic pump in a first direction when the electric machine is operating in the forward direction and when the electric machine is operating in the reverse direction.
