Abstract: A vapor compression heat pump (VCHP) system for an electrified vehicle and a method for de-icing the VCHP system is provided. The electrified vehicle may include a vehicle cabin, the VCHP system, and a controller. The VCHP system may be in thermal communication with the cabin and include an outside heat exchanger and a compressor. The controller may be configured to, in response to detection of a predefined ice condition associated with the outside heat exchanger, output commands to adjust a speed of the compressor to influence a temperature of refrigerant flowing through the compressor such that the refrigerant carries an amount of heat sufficient to eliminate the predefined ice condition within a preselected time period. The predefined ice condition may be a condition in which the heat exchanger has accumulated ice or is likely to accumulate ice.

Abstract: Methods and system for operating a heat pump in different operating modes and providing a predictable heat pump response when the heat pump is transitioned between the different operating modes are presented. In one example, a controller that includes executable instructions for providing a bumpless compressor command for operating the heat pump is disclosed.

Abstract: A vehicle climate control system for an electrified vehicle including a thermal circuit and a controller is provided. The thermal circuit includes a heat pump and a positive temperature coefficient (PTC) heater. The controller is programmed to direct operation of the heat pump and the PTC heater responsive to receipt of a request for simultaneous cooling and heating based on a heat source mode table and detection of a system configuration in which flow is permitted through one of a fixed orifice expansion device (FOT), a thermal expansion valve (TXV), and an electronic expansion valve (EXV). The heat source mode table may call for the heat pump to operate in a cool mode and the PTC heater to operate in a heat mode when heater core coolant is identified as warm and ambient temperature is above a predetermined threshold.

Abstract: A vehicle system includes a user interface device and an autonomous mode controller. The user interface device receives a user input representing a driving mode selection. The autonomous mode controller commands one or more vehicle subsystems to operate in accordance with characteristics associated with the driving mode selection. Examples of characteristics can include how aggressively the vehicle accelerates or decelerates, a minimum distance from the vehicle to a front vehicle, or how frequently the vehicle changes lanes, among others.

A vehicle layer transmits arbitrated torque request signals indicative of first and second amounts of torque and at least one torque reservation request signal indicative of whether the vehicle is in an anticipated vehicle dynamic state or in a non-anticipated vehicle dynamic state. A coordination layer controls the torque generating device to generate the first amount of torque in response to the arbitrated torque request signal and the torque reservation request signal indicating that the vehicle is in the non-anticipated vehicle dynamic state. The coordination layer controls torque generating device to generate the second amount of torque in response to the arbitrated torque request signal and the torque reservation request signal indicating that the vehicle is in the anticipated vehicle dynamic state.
