Embodiment Construction

[0052] figure 1 Diagrams are shown for making the present invention easy to understand. figure 1 The predicted exterior temperature profile, the interior-actual temperature profile and the predicted heat input profile in the bus-interior space (e.g. Depending on the external temperature, the internal temperature, the mass of the bus, the insulation of the walls and windows of the bus, etc.) and the theoretical internal temperature profile (e.g. constant 20°C), which is at least approximately to get.

[0053] figure 2 and 3 A flow chart for an air-conditioning system operating method according to an exemplary embodiment of the invention is shown. This run method traces back to figure 1 In order to save energy consumption to run the air conditioning equipment.

[0054] In step S1 , the route to be traveled by the bus (travel route) is determined according to the lapse of time (for example from a travel plan or from a navigator). Since the driving route is known in advanc...

Abstract

The invention relates to an operating method for at least one air conditioning system of a vehicle used for calculating at least one temperature adjusting plan in advance for a determined driving route or at least one road section. The operating method is characterized by following steps: preferably determining expected vehicle-internal space-theoretical temperature; determining a driving route; measuring at least one predicted parameter comprising predicted outside weather in the driving route or at least one road section and / or predicted heat input to internal space of the vehicle in the driving route or at least one road section; and measuring at least one temperature adjusting plan for the driving route or at least one road section according to measured predicted parameter. The operation method is also characterized by the step of measuring the temperature adjusting plan of air conditioning equipment of the vehicle by means of a controlling computer outside the vehicle and preferably remotely controlling the air conditioning equipment of the vehicle according to the temperature adjusting plan by means of remote information technology.

Description

technical field [0001] The invention relates to a method for operating an air-conditioning system of at least one motor vehicle, preferably for precalculating at least one temperature control plan for a certain driving route or at least one road section therein. The motor vehicle is preferably a bus, expediently used for public short-distance passenger transport (PNV), which is used repeatedly as usual on at least one predetermined and thus previously known travel route (eg cycle). Background technique [0002] The control (regulation) of bus air-conditioning systems is today usually carried out based on predefined setpoint values ​​(eg 22°C). Control usually takes place via the driver's setpoint input, measurement of the outside temperature and measurement of the interior space temperature. The control of the air-conditioning system takes place via the delivery rate of the compressor, but can also take place via subsequent heating in the air flow by means of temperature co...
