Abstract

The invention provides an automobile idle speed start-stop system and a hybrid power supply. The automobile idle speed start-stop system comprises an energy storage unit, a starting motor, a motor driver, a power electronic converter device, an automobile state monitoring device and an electronic control unit, wherein the energy storage unit comprises a storage battery and a super capacitor; the starting motor is connected to an engine of an automobile; the motor driver is connected to the starting motor; the power electronic converter device is connected to the storage battery, the super capacitor and the motor driver; and the electronic control unit is in communication connection with the motor driver, the automobile state monitoring device, the power electronic converter device, the starting motor, the motor driver and the energy storage unit and is used for judging whether the automobile is started, normally operated, stopped at an idle speed or stopped or not according to parameters detected by the automobile state monitoring device so as to control the running of the engine and the motor driver, the operation of the power electronic converter device and the energy transfer between the energy storage unit and the starting motor. By the system, the automobile can be quickly started, the economy of fuel can be improved, and the service life of the storage battery can be prolonged.

Description

technical field [0001] The invention relates to an automobile control system, in particular to an automobile idling stop and start system (ISS for short) and a composite power supply. Background technique [0002] The depletion of energy sources, rising oil prices, and deteriorating global climate and environment further highlight the fact that energy-saving and environmental protection technologies in the development of automotive products are major technical challenges facing the global automotive industry today. By canceling the parking idle speed, eliminating idle fuel consumption, emission and noise, and then achieving energy saving, emission reduction and noise reduction, the effect is remarkable, especially for urban vehicles, the effect is more obvious. [0003] In cities, due to the concentration of population and vehicles, problems such as low speed, high fuel consumption, serious emissions and noise are caused. Especially for urban buses, because there are many s...
