Abstract: A thermal system for a vehicle includes a refrigerant loop operable between a cooling mode and a heat pump mode, a compressor configured to circulate a refrigerant through the refrigerant loop, and a heat exchanger disposed on the refrigerant loop and configured to operate as a condenser when operating in the cooling mode and operate as an evaporator when operating in the heat pump mode. A thermal control system includes a controller having one or more processors. The controller is programmed to perform an assessment of ambient conditions, estimate an incremental ice formation on the heat exchanger based on the assessed ambient condition, and initiate a deicing operation of the heat exchanger when the incremental ice formation exceeds a predetermined threshold.

Abstract: A securement technique for a vehicle for vehicle-to-everything (V2X) power generation includes receiving, from a transmission shifter, a requested state for the transmission from the park state where a park pawl is engaged and one or more non-park states where the park pawl is disengaged, detecting for a key fob associated with the vehicle, detecting, via a user interface device, a lock request associated with a power generation mode during which a powertrain of the vehicle is configured to operate in a generator mode and output electrical power, in response to the lock request, commanding an actuator to physically lock the shifter while the transmission is in the park state and the park pawl is engaged and when the key fob is not detected, keep the park pawl engaged without regard to a requested non-park state from the shifter.

Abstract: A vehicle system having an automatic vehicle securement feature to prevent an unoccupied vehicle from driving away includes a controller programmed to initiate the automatic vehicle securement feature, if a first set of conditions is satisfied, by engaging the parking brake and/or parking pawl to thereby prevent the vehicle from driving away. The controller determines if there is a fault of the first set of conditions, if the first set of conditions is not satisfied, and then determines, by the camera-based monitoring system, if a driver is present within the vehicle, if there is a fault of the first set of conditions. The controller initiates the automatic vehicle securement feature if the driver is determined not present within the vehicle, even though the first set of conditions is not satisfied.

Abstract: An electric drive module (EDM) for an electrified vehicle is provided. The EDM includes a housing; an electric motor; a single compound planetary gear set having a sun gear fixed to its input shaft, a single planetary carrier rotationally supporting pairs of compound planets in engagement with the sun gear and a ring gear, respectively; and first and second torque transfer devices (TTDs) coupled to the carrier. An output of the motor is connected to the input shaft and an output of the EDM is connected to a final drive gearset. The EDM is selectively switchable among: (i) a first gear where the first TTD is disengaged and the second TTD is engaged grounding the carrier to the housing, and (ii) a second gear where the second TTD is disengaged and the first TTD is engaged to couple for common rotation the carrier and the sun gear.

Abstract: An autonomous cruise control (ACC) system that implements a corrective action strategy based on driving conditions for a vehicle is provided. The ACC system includes a drive unit, vehicle sensors and a controller. The controller: receives at least signal from at least one vehicle sensor indicative of a driving condition; determines, based on the signal, whether the at least one signal satisfies a threshold indicative of an unsafe driving condition; and performs the corrective action strategy based on the determination that at least one signal satisfies an unsafe driving condition. The corrective action strategy comprises at least one of: (i) increasing a preset distance to a target vehicle; (ii) communicating a message to a human machine interface indicative of an unsafe driving condition; (iii) communicating a signal to vehicle brakes to initiate a braking event; and (iv) communicating a signal to a traction control system to alter an acceleration setting.

Abstract: Refueling control techniques for a fuel cell electrified vehicle (FCEV) involve providing an electrified vehicle control unit (EVCU), a fuel cell propulsion system (FCPS), and a controller area network (CAN) therebetween, providing a set of hardwire wakeup lines connecting from the EVCU to each of the FCPS and other primary modules, and configuring the FCPS to act as a primary controller during refueling operations of the FCEV where a fuel is provided to the FCEV via a fuel hose and a fuel supply system. The EVCU is configured to act as a secondary controller during the refueling operations such that it and the other modules connected via the set of hardwire wakeup lines are able to transition to an asleep state to save low voltage power during the refueling operation.
