Abstract

The invention discloses a car engine BSG start and stop control method and device and relates to the technical field of cars. According to the method, when a crankshaft is combined with a pulley system, the pulley system is driven by the crankshaft, and the BSG is in a power generator state; when the crankshaft is separated with the pulley system, the BSG is in a motor state and operates in the preset rotating speed, and the normal operation of attachments are maintained. An additional sensor is omitted, the original pulley system is free of changing, the ideal fuel saving effect is achieved, the entire car cost is low, the development period is short, and the production investment is low. The device comprises a BSG pulley, and the BSG pulley, a power assisted steering pump pulley, a water pump pulley, an air conditioning compressor pulley and a crankshaft pulley are connected through a belt; the entire original engine pulley system and transmission are maintained, the pulley system is free of changing, the development of the pulley system is omitted, and only an one-way bearing is arranged in the hub portion of the original crankshaft pulley as required.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method and device for reducing fuel consumption of automobiles. Background technique [0002] In order to reduce fuel consumption, when the car is decelerating and coasting, the engine is idling. If the engine is turned off at this time, it can save a lot of fuel. When it is necessary to continue driving or accelerate, the engine fires up again. For example, 1 is a typical pulley system of the engine, a belt connects the generator pulley 11, the power steering pump pulley 3, the water pump pulley 4, the air conditioner compressor pulley 5 and the crankshaft pulley 1, and the generator is driven by the engine , power steering pump, water pump and air conditioning compressor work. In the above process, once the engine stops working, the vehicle can no longer travel. Because, the attachment on the engine pulley train no longer works. For example, once the power ste...
