Embodiment Construction
[0028] In order to solve the comfort problem of the automatic air conditioner when the automobile engine is automatically stopped, the technical scheme of the present invention comprehensively considers the relationship between the automobile engine downtime and the comfort of the air conditioner, and proposes an automobile air conditioner start-stop control system and a control method thereof.
[0029] Such as figure 1 As shown, the automotive air conditioner start-stop control system provided by the embodiment of the present invention includes:
[0030] The ambient temperature sensor 101 is suitable for collecting signals of the ambient temperature outside the vehicle;
[0031] The warm air core sensor 102 is suitable for collecting signals of the surface temperature of the warm air core when the air conditioning system is heating;
[0032] The interior temperature sensor 103 is suitable for collecting signals of interior temperature;
[0033] The sunlight sensor 104 is suitable for c...

An automobile air-conditioning start-stop control system and a control method thereof, the method comprising: after receiving the engine automatic shutdown signal, if the first condition is met, the automatic engine shutdown is prohibited, otherwise the engine is allowed to automatically stop; the first condition includes: The air-conditioning system is in defrosting or defogging mode, or the ambient temperature is higher than the first temperature threshold or lower than the second temperature threshold, or the light intensity is greater than or equal to the light threshold, or the difference between the target temperature controlled by the air-conditioning system and the interior temperature is greater than the second A temperature difference threshold; after the engine is automatically shut down, if the second condition is met, the engine is requested to be started, otherwise the engine is kept in the shutdown state; the second condition includes: the air conditioning system is in the defrosting or defogging mode, or the engine is automatically shut down. The temperature change exceeds the temperature change threshold, or the difference between the target temperature controlled by the air conditioning system and the vehicle interior temperature is greater than or equal to the second temperature difference threshold. The technical proposal can not only save fuel consumption, but also maintain the comfort of the air-conditioning system.
Description
Technical field [0001] The invention relates to the technical field of automobile control, in particular to an automobile air conditioner start-stop control system and a control method thereof. Background technique [0002] As the country has higher and higher requirements for automobile fuel consumption, various automobile manufacturers are studying fuel-saving measures, and the start-stop function is one of the fuel-saving measures. The so-called start-stop function means that the engine will automatically stop when the vehicle encounters a red light during driving; after the green light, the vehicle will automatically start and continue driving, thereby saving fuel. However, after the engine is automatically shut down, the compressor and the coolant circulating water pump stop working, which will cause the problem of reduced comfort of the automatic air conditioning system. [0003] In order to solve the problem of reduced comfort of the air-conditioning system, the usual solut...
