Abstract

The invention discloses an automobile waste heat recovery control method, electronic equipment and a system. The method comprises the steps that the operation state of an automobile engine is detected, and the water temperature of the engine is detected if the engine runs; and according to the water temperature of the engine, the exhaust power of waste gas exhausted to a waste gas heat exchanger is adjusted, an exhaust pipe of the engine communicates with the gas inlet end of the waste gas heat exchanger, and a cooling liquid channel of the engine, a liquid channel of the waste gas heat exchanger and a heating device used for adjusting the temperature of an automobile passenger compartment are connected in series to form a liquid channel loop. According to the automobile waste heat recovery control method, the electronic equipment and the system, accurate control over heat recovery is achieved, and the damage risk caused by heat accumulation is avoided; meanwhile, different flow control is set according to the waste heat recovery degree, and optimal recovery control is achieved; waste heat recovery is carried out in combination with functional requirements of different running modes of an air conditioner, and optimal heat utilization is achieved; and finally, by setting waste heat recovery control after the engine is stopped, heat is recovered to the maximum extent, and heat accumulation in an EHRS can be reduced.

Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to an automobile waste heat recovery control method, electronic equipment and a system. Background technique [0002] When the car is running, the engine emits waste heat. In the prior art, the waste heat recovery system is used to improve the fuel consumption and the heating effect of the air conditioner. [0003] The existing Exhaust Heat Recovery System (EHRS) is generally used for waste heat power generation or using waste heat to heat water for engine warm-up and air conditioning heating. [0004] However, the use of waste heat to generate electricity is costly, resulting in low cost performance. [0005] Therefore, the use of waste heat recovery in the prior art mostly uses waste heat to heat water for engine warm-up and air-conditioning heating. [0006] However, the existing technology of using waste heat to heat water for engine warm-up and air-conditioning h...
