The invention relates to a method for operating a climate-control system (12) for a vehicle (10). According to the invention, total energy efficiencies are determined for a group of operating strategies for the air-conditioning system (12) and an operating strategy with the greatest total efficiency that fulfills the heating output requirement (44) that has been determined, is selected.

A computer includes a processor and a memory, the memory storing instructions executable by the processor to receive first input to sanitize a vehicle passenger cabin via a passenger cabin heater, output one or more candidate initiation times at which to begin actuation of the heater, and, then, actuate the heater to a temperature above a specified sanitization threshold according to the initiation time identified in a second input.

A computer includes a processor and a memory, the memory storing instructions executable by the processor to heat a passenger cabin of a vehicle and to actuate a vehicle security subsystem to prevent entry into the vehicle upon initiation of a cabin sanitizing operation, wherein the sanitizing operation includes actuating a heater to heat the passenger cabin above a temperature threshold.

An electric heating device may heat an air flow through a duct of a ventilation, heating and/or air-conditioning installation of an automotive vehicle. The heating device may include at least one heating module that is contained in a heating body. The heating body may include a housing for controlling and supplying electrical power to the at least one heating module. The housing may include, in its interior, a printed circuit board from which a power supply connector and a control connector protrude. The housing may also include a power supply opening such that the power supply connector emerges from the housing and a control opening such that the control connector emerges from the housing. The housing may include a skirt that protrudes in parallel to the control connector on the periphery of the control opening. The skirt may be formed as a single part with the housing.

A heating rod having a plurality of ceramic heating elements, a first strip-shaped contact sheet, a second strip-shaped contact sheet, and a housing in which the plurality of heating elements and the contact sheets are arranged. The first contact sheet electrically contacts only a part of the plurality of the heating elements, and the second contact sheet electronically contacts a second part of the plurality of the heating elements.

A vehicle air-conditioning system has an intake door that switches between an inside air recirculation mode to take in air from an inside air introduction port and an outside air introduction mode to take in air from an outside air introduction port, a blower that blows the air introduced through any of the inside air introduction port and the outside air introduction port toward inside of a vehicle cabin, a heater that heats the air blown by the blower, and a controller that activates the heater when there is a request for heating the inside of the vehicle cabin, controls air conditioning such that an environment inside the vehicle cabin becomes a desired environment by set estimated time of departure.

A vehicular thermal management system includes: an indoor-air-conditioner disposed in a first vehicle body having a passenger space and including a compressor, a first condenser, an evaporator, a blower, and a refrigerant line; and a component-air-conditioner disposed in a second vehicle body combinable with the first vehicle body and including an electrical component line for cooling an electrical component of the vehicle and a first battery line for cooling a high-voltage battery including a chiller which extends toward the first vehicle body to be disposed behind the evaporator when the first vehicle body is combined with the second vehicle body.

An apparatus for controlling a vehicle, which includes: a battery (3) capable of being charged from an external power source (EPS); a power generation unit (PGU) capable of charging the battery (3); an electric heater (12) configured to produce heat with electric power from an electric power source; a heater core (11) configured to heat air by using any one of waste heat from the power generation unit (PGU) and the electric heater (12); and a controller (19) configured to perform control for selectively using the waste heat from the power generation unit (PGU) and the electric heater (12) as a heat source of the heater core (11) when the vehicle is parked.

A method for climate control, in which an overall mass flow of air is guided through an auxiliary heater, which has multiple zones. The overall mass flow is divided after flowing through the auxiliary heater into multiple partial mass flows, and an nth partial mass flow respectively flows out of an nth zone. A value of at least one flow parameter of an nth partial mass flow is ascertained, and at least one manipulated variable of a respective nth zone is set in dependence on the value of the at least one flow parameter. Overheating of at least one zone of the auxiliary heater is avoided.
