A method of controlling a temperature altering element within a seating assembly of a vehicle comprising: presenting a vehicle including a seating assembly including a temperature altering element, a controller in communication with the temperature altering element, the controller including a Pre-established Predictive Activation Model setting forth rules governing the activation of the temperature altering element as a function of data relating to Certain Identifiable Conditions, and a user interface configured to allow the temperature altering element to be manually activated or deactivated; occupying the seating assembly with a first occupant; collecting data relating to the Certain Identifiable Conditions while the first occupant is occupying the seating assembly; determining, by comparing the collected data to the rules of the Pre-established Predictive Activation Model, whether the collected data satisfies the rules of the Pre-established Predictive Activation Model so as to activate the temperature altering element; and activating the temperature altering element.

A heating system for a vehicle includes: a heater for non-contact heating that emits radiation heat by heat supplied from its heat generating part, which generates heat upon energization, to give warmth to an occupant in a state where a body of the occupant is not in contact with the heater; a heater for contact heating that generates heat upon energization to give warmth to the occupant in a state where the body of the occupant is in contact with the heater; and a control device that controls operations of the heater for contact heating and the heater for non-contact heating. The control device adjusts a heating output provided by the heater for contact heating and a heating output provided by the heater for non-contact heating, and controls the operations. Therefore, the occupant can enjoy a sense of heating that is not stereotypical, and achieve energy saving.

An air conditioning system has a heat pump, a first-liquid-medium circuit in which a first liquid medium circulates, a second-liquid-medium circuit in which a second liquid medium circulates, a heat source, a connection switching device, and a controller. The connection switching device switches between a connection state in which the heat source is connected to the second-liquid-medium circuit and a disconnection state in which the heat source is disconnected from the second-liquid-medium circuit. The controller controls the connection switching device to switch between the connection state and the disconnection state based on a heat-related physical quantity relating to a heat of the first-liquid-medium circuit, a heat-related physical quantity a heat of the second-liquid-medium circuit, a heat-related physical quantity the heat generated by the heat source, or a heat-related physical quantity a heat of the heat pump.

A radiant heating system includes a radiant heating element, a steering wheel position monitoring device and a controller configured to control the radiant heating element in response to steering wheel position data received from the steering wheel position monitoring device. A method of controlling operation of a radiant system.

There is disclosed an air conditioning device of a so-called heat pump system which efficiently and comfortably heats a vehicle interior. In a vehicle air conditioning device 1, a controller executes a heating mode in which a refrigerant discharged from a compressor 2 radiates heat in a radiator 4 and the refrigerant by which heat has been radiated is decompressed and then absorbs heat in an outdoor heat exchanger 7. The vehicle air conditioning device includes a heating medium circulating circuit 23 to heat air to be supplied from an air flow passage 3 into the vehicle interior, and the controller executes the heating by a heating medium-air heat exchanger 40 of the heating medium circulating circuit 23, when a heating capability by the radiator 4 runs short.

A vehicle air-conditioner safety device includes a controller which, in a case in which an abnormality has occurred in a heating device that heats coolant with a heater, determines whether or not the abnormality is a restorable abnormality or a non-restorable abnormality. When the abnormality is determined to be the restorable abnormality, it is determined whether or not the restorable abnormality has been removed. Heating by the heater is prohibited when the restorable abnormality or the non-restorable abnormality has occurred. Heating by the heater is restored when the restorable abnormality has been removed after heating by the heater is prohibited due to occurrence of the restorable abnormality.

A method of controlling a temperature altering element within a seating assembly of a vehicle comprising: presenting a vehicle including a seating assembly including a temperature altering element, a controller in communication with the temperature altering element, the controller including a Pre-established Predictive Activation Model setting forth rules governing the activation of the temperature altering element as a function of data relating to Certain Identifiable Conditions, and a user interface configured to allow the temperature altering element to be manually activated or deactivated; occupying the seating assembly with a first occupant; collecting data relating to the Certain Identifiable Conditions while the first occupant is occupying the seating assembly; determining, by comparing the collected data to the rules of the Pre-established Predictive Activation Model, whether the collected data satisfies the rules of the Pre-established Predictive Activation Model so as to activate the temperature altering element; and activating the temperature altering element.

A method for digitally controlling a heating arrangement may include receiving a temperature value with a control device, the temperature value reflecting a current outside temperature. The method may also include determining via the control device, based on the received temperature value, a limit output of the heating arrangement that is smaller than a maximum output of the heating arrangement. The method may further include dividing the determined limit output into a plurality of output stages via the control device, a number of the plurality of output stages corresponding to a digital resolution of the control device. The method may additionally include controlling the heating arrangement between a minimum output and the limit output to one of the plurality of output stages.

A method for managing mileage capacity of a BEV having a TRU includes obtaining live vehicle data via an ECU of the BEV and determining a rate of consumption of energy stored in the energy storage unit and an efficiency of BEV's components based on the live vehicle data. The method further includes triggering an operation mode of the BEV based on the determined rate of consumption of energy and the efficiency, and thereafter controlling a cooling and a heating capacity of the TRU based on the triggered operation mode. The method includes optimizing the rate of the consumption of energy based on the controlled cooling and the heating capacity of the TRU and then notifying a message indicating current operating modes of the BEV and activation of an energy saving mode to a user of the BEV via one of a HMI, mobile application, or a visual indicator.

Systems and methods of controlling temperature in a cabin of an electric vehicle that has an HVAC system powered by a battery system and an auxiliary heating system. Upon determining, by a system controller, that a setpoint temperature is less than or equal to a sensed cabin temperature while operating in an HVAC electric heat state, an auxiliary heat state, or a maximum heat state, automatically transitioning to an off state from the HVAC electric heat state, the auxiliary heat state, or the maximum heat state.
