A control method and control system for an automobile electrical appliance

Abstract

The invention belongs to the technical field of automobile components and provides an automotive electric appliance control method. The automotive electric appliance control method includes detecting electric quantity of a storage battery; controlling primary electric appliances, secondary electric appliances and tertiary electric appliances to turn off according to the electric quantity of the storage battery, and giving prompt signals; judging whether to start to charge the storage battery or not according to the prompt signals; judging whether charging the storage battery is started or not, and if yes, recording charging time and detecting the electric quantity of the storage battery; according to the electric quantity and charging time of the storage battery, judging whether to stop charging or not and controlling the prompt signals to cut off. The automotive electric appliance control method has the advantages that the primary electric appliances, the secondary electric appliances and the tertiary electric appliances are controlled to be turn on or off and whether the storage battery is charged or not are controlled according to the electric quantity of the storage battery; the electric quantity of the storage battery can be allocated reasonably, and the requirements of continuously load increase can be met without increasing power of an electric generator and capacity of the storage battery, so that production cost is lowered, fuel consumption is reduced and energy resources are saved.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, and in particular relates to a control method and a control system for electric appliances used in automobiles. Background technique [0002] There are more and more electronic devices in the car, which leads to the continuous increase of the load of the car. The electrical system of the car is becoming more and more complex, and the requirements for the balance of the electric power of the whole car are constantly increasing. When the configuration of the whole car increases too much, the existing processing methods usually In order to increase the power of the generator or increase the capacity of the battery to meet the loss of electrical appliances. Increasing the power of the generator or the capacity of the storage battery will increase the weight and production cost of the vehicle, and increase fuel consumption, resulting in waste of resources and energy.
