In one embodiment, a method includes, by a computing system of a vehicle, determining a first temperature of a control unit of the vehicle, wherein the control unit and one or more components of the vehicle are interconnected through a thermal network, determining a thermal objective for the control unit based on the first temperature of the control unit, selecting, based on the thermal objective for the control unit, at least a first component from the one or more components, and sending one or more signals to one or more actuators within the thermal network to enable a heat-transfer fluid to flow between (1) a first portion of the thermal network thermally coupled to the control unit and (2) a second portion of the thermal network thermally coupled to the selected first component.

The present patent application relates to a high-voltage motor vehicle electrical system comprising an electrical heating device and at least on further consumer during switching on of which, undesired electromagnetic oscillations may occur in the electrical system. According to the invention, these are suppressed by initially switching on the heating device, before the further consumer is switched on. Switching on the heating device changes the complete impedance of the electrical system such that a resonant enhancement of the interference oscillations is prevented. Preferably, the heating device is switched on only as shortly as possible (only during the switching on process of the further consumer) in order to minimize an undesired heating.

An air conditioner for a vehicle includes a cooling water circuit and a heater. The cooling water circuit allows a cooling water to circulate between an engine and a heater core in a heating operation. The engine is a power source of the vehicle. The heater core is configured to heat air using a heat of the cooling water. The heater is located downstream of the engine and upstream of the heater core in the cooling water circuit and is configured to heat the cooling water.

System and methods are provided for improving fuel economy, and providing optimized operating conditions associated with a vehicle's air-conditioning system when the vehicle is carrying a load, e.g., towing a trailer. Operating conditions including, for example, air-mix setting, coolant temperature, ambient temperature, vehicle speed, and whether or not the vehicle is carrying the aforementioned load, may be considered when determining whether or not to activate or deactivate a vehicle heating element, such as a positive temperature coefficient (PTC) heater, steering wheel heater, etc.

A heating apparatus for a vehicle includes an air heating unit configured to heat air conditioning air to be sent into a vehicle cabin, a contact heating unit configured to heat a member that is in contact with a body of an occupant in the vehicle cabin, and an electronic control unit. A heat source of the air heating unit and a heat source of the contact heating unit each are supplied with an electric power from one or more batteries. The electronic control unit is configured to decrease an electric power that is supplied to the heat source of the air heating unit when the heat source of the contact heating unit is on as compared to an electric power that is supplied to the heat source of the air heating unit when the heat source of the contact heating unit is off.

Systems and methods for managing auto start of a vehicle during an auto-stop condition may include determining an operational status of a vehicle climate control system; receiving a target air outlet temperature from the vehicle climate control system; receiving data indicating a state of a heated seat of the vehicle; and inhibiting a start-vehicle command to restart the vehicle because of a cabin heating requirement when the data indicates that the heated seat of the vehicle is activated.

A thermal management system for an electric vehicle includes an interior air conditioning part including an air inflow part, an air discharge part, a cooling core, a heating core arranged between the cooling core and the air discharge part, and an adjustment door for selectively adjusting whether air having passed through the cooling core flows into the heating core; and a heat transfer line having first and second sides respectively connected to an electric part core and the heating core to be heat-transferrable, so that heat of the electric part is transferred to the heating core, thereby allowing the electric part to heat-dissipate through the heating core.

A vehicular heat management system includes a heat medium circuit, a heat source portion, and a device. A heat medium cooling an engine circulates in the heat medium circuit. The heat source portion heats the heat medium. The device is configured to function and heat the heat medium when the heat medium flowing into the device is at or above a predetermined temperature. When the engine is being warmed up, heat generated by the heat source portion is supplied to the device in preference to the engine. According to this, since the heat generated by the heat source portion is supplied to the device in preference to the engine when the engine is being warmed up, the engine can be warmed up early.
