Abstract

The invention provides a micro hybrid power system and control method and relates to the technical field of hybrid vehicles. The micro hybrid power system comprises an accessory device, an engine, a clutch, a transmission, a differential mechanism and a running wheel which are connected with each other in sequence in a transmission manner; a first clutch device is arranged between a crank transmission wheel of the engine and an engine main body; the accessory device comprises an integrated motor and an air conditioning compressor; the integrated motor is connected with the crank transmission wheel in a transmission manner; the air conditioning compressor is connected with the crank transmission wheel in a transmission manner; a second clutch device is arranged between the air conditioningcompressor and the crank transmission wheel; the integrated motor, an automobile controller and an automobile storage battery are electrically connected with each other; and the first clutch device and the second clutch device are both connected with the automobile controller. The invention aims at providing the micro hybrid power system and control method to solve the problems that the economy and comfort of a mechanical air conditioner in the prior art cannot be realized at the same time and the cost of an electronic air conditioner in the prior art is high.

Description

technical field [0001] The invention relates to the technical field of hybrid vehicles, in particular to a weak hybrid system and a control method. Background technique [0002] The powertrain of traditional fuel vehicles such as figure 1 As shown, the front end of the engine is an accessory system driven by a belt drive. The accessory system includes at least a generator and a mechanical air-conditioning compressor. These accessories are connected to the engine crankshaft pulley through a belt and obtain the required power from the crankshaft pulley. Usually, the generator and the generator pulley are directly connected, and the crankshaft pulley is also directly connected to the crankshaft. In a traditional power system, when the engine is shut down, the air conditioner compressor cannot continue to work due to loss of power. [0003] In the hybrid system, when the car is coasting or waiting, the system can choose to turn off the engine to reduce fuel consumption and imp...
