Embodiment Construction

[0016] A method for operating a motor vehicle relates to a motor vehicle comprising an engine, a passenger compartment and a system arrangement for passenger compartment air conditioning with a passenger compartment heating heat exchanger. The method comprises the following steps: first a passenger compartment temperature setpoint value T0 and a minimum passenger compartment temperature value T1 are defined. Then, the system device for air conditioning of the passenger compartment is operated, wherein only when the actual temperature T of the passenger compartment falls below the defined minimum passenger compartment temperature value T1 and / or when the engine has reached its operating temperature, the Coolant is supplied to the passenger compartment heating heat exchanger.

[0017] In other words, the passenger compartment is first conditioned or heated only to a defined minimum passenger compartment temperature T1 , with priority being given to heating the engine to its oper...

Abstract

The present invention involves the consumption optimization system for adjusting the air -conditioning air conditioning air in motor vehicles. Provide methods and systems for controlling the air conditioning system for controlling motor vehicles. In one example, the cabin of the vehicle may be first heated to a first temperature by flowing the coolant to the heat exchanger, the coolant may be moved out of the heat exchanger and towards the engine to increase the temperature of the engine, and the coolant may then flow again to the heat exchanger an exchanger to heat the cabin to the second temperature. The amount of fuel saving generated by heating the engine from the heat exchanger can be displayed to the vehicle operator by the display device.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from German Patent Application No. 102016200940.0 filed on January 22, 2016. The entire content of the aforementioned application is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present description generally relates to methods and systems for controlling coolant flow through an air conditioning system of a motor vehicle. Background technique [0004] In motor vehicles, passenger compartment air conditioning can have a significant impact on fuel consumption. For example, coolant that has been heated by the engine after a cold start may be supplied to a passenger compartment heating heat exchanger in order to increase the temperature of the passenger compartment of the vehicle. If the desired passenger compartment temperature that has been set is not reached (eg, via automatic adjustments), heat may be extracted from the coolant. As a ...
