Abstract

This invention is related to the vehicle electronic technology, especially a method of effectively preventing start failure risk of the vehicle and a vehicle electronic controller based on this method. As per the embodiment of this invention, the method of controlling vehicle start failure risk includes the following steps: gaining the current power load state of the mentioned storage battery; determining the risk factor of next start failure of the vehicle according to the current power load and the historical data of voltage decrease of the storage battery during the starts of the vehicle; and determining the current working condition of vehicle power load according to the risk factor.

Description

technical field [0001] The invention relates to automobile electronic technology, in particular to a method for controlling the charging process of an automobile storage battery and an automobile electronic controller based on the method. Background technique [0002] The vehicle power supply system mainly consists of an energy storage device (such as a battery or a supercapacitor), an energy conversion device (such as a generator that converts mechanical energy into electrical energy), a starter and a control unit. In the vehicle power supply system, the control unit is the core of the whole system, which is responsible for determining and implementing the appropriate power management strategy according to the working conditions such as power load, battery status and generator status. The starter uses the energy of the battery to start the car engine and make the engine run in the required working state. When the engine is running, it will drive the generator to generate e...
