Vehicle internal combustion engine control system

Abstract

An automotive internal combustion engine control system that transmits the output of a starter motor (4) capable of operating as a generator to an internal combustion engine (1) to start the internal combustion engine, and transmits the output of the internal combustion engine to accessory equipment ( 5, 6, 7). The automotive internal combustion engine control system includes a transmission mechanism (20), which transmits the output of the starter motor to auxiliary equipment when the internal combustion engine is stopped under a predetermined condition, and when the internal combustion engine is started under a high first gear ratio, it will start the output of the motor drive shaft. Rotation is transmitted to and operated by the internal combustion engine, and the starter motor transmits rotation of the crankshaft of the internal combustion engine to the starter motor drive shaft at a low second gear ratio when the internal combustion engine operates as a generator. When the internal combustion engine stops running, the transmission mechanism can drive the auxiliary equipment through the starter motor, start the internal combustion engine smoothly and effectively regenerate energy when the internal combustion engine is running.

Description

technical field [0001] The present invention relates to a control system for controlling the power transmission from a starter motor to an internal combustion engine, and from the internal combustion engine to auxiliary equipment in a vehicle, such as an automobile. Background technique [0002] When a vehicle with an internal combustion engine is stopped, for example, while waiting for a traffic light to change, techniques for temporarily stopping the internal combustion engine have been found to reduce the fuel consumption of the internal combustion engine. Often, an ancillary device, such as an air conditioner, stops running when the internal combustion engine stops, so hot air in the passenger compartment can make the passenger compartment uncomfortable. [0003] A technique has been proposed in which an electric motor drives auxiliary equipment while the internal combustion engine is stopped. In the Japanese patent JP-A230012 / 1999, a technique for preventing useless po...

Problems solved by technology

[0004] However, the prior art does not use the electric motor as both a drive device and a generator, and does not use the electric motor for power regeneration

[0005] For cars with air conditioning, it is wise to temporarily regenerate the energy that can be recovered when the internal combustion engine stops, because the power loss of the air conditioner is large
