Embodiment 1

[0037] Embodiment 1 of the present invention proposes an automobile generator control method, which can be applied to, for example, the automobile generator control system described in Embodiment 2. The automobile control system includes an information detection element and a control unit, and the control unit includes Engine controllers and generator regulators.

[0038] figure 1 It is a schematic flow chart of a method for controlling an automobile generator in Embodiment 1, see figure 1 , the method includes the steps of:

[0039] Step S101, acquiring the charging and discharging information of the vehicle battery and the duty cycle information of the generator.

[0040]Specifically, in the step, the charging and discharging information of the car battery and the duty cycle information of the generator can be obtained through the information detecting element. More specifically, the information detecting element can include a first information detecting element and a seco...

Embodiment 2

[0068] Embodiment 2 of the present invention proposes a generator control system, figure 2 It is a schematic structural diagram of a generator control system in Embodiment 2, see figure 2 , the system includes:

[0069] The information detection element 1 is used to obtain the charging and discharging information of the car battery and the duty cycle information of the generator;

[0070] A control unit 2, configured to control the operation of the automobile generator according to the charging and discharging information and the duty cycle information;

[0071] Wherein, the control unit 2 includes an engine controller 21 and a generator regulator 22. If the vehicle battery is in a discharge state and the duty cycle of the generator is greater than a preset ratio threshold, the engine controller 21 generates a first control command, The generator regulator 22 releases the limitation of the excitation current of the generator according to the first control command.

Abstract

The invention relates to a generator control method and system, and the method comprises the steps: obtaining the charging and discharging information of an automobile storage battery and the duty ratio information of a generator through an information detection element, controlling an automobile generator to operate according to the charging and discharging information and the duty ratio information through an engine controller and a generator regulator to realize voltage stabilization of the whole automobile; wherein if the automobile storage battery is in the discharging state and the dutyratio of the generator is larger than the preset proportion threshold value, the excitation current limitation of the generator is relieved. According to the invention, the voltage of the whole vehicle is stabilized by adjusting the control logic of the generator and setting main parameters in the regulator, and a DC / DC converter is prevented from being added.

Description

technical field [0001] The invention relates to the technical field of automobile generator control, in particular to a generator control method and system thereof. Background technique [0002] With the rapid development of automotive electronics technology, traditional electronic appliances and intelligent network technology are changing with each passing day, and the large increase in electrical systems and control modules has caused the power consumption of the vehicle's electrical system to increase, and the demand for electrical energy in the vehicle's electrical system is increasing. Large, the maintenance of vehicle voltage stability by the vehicle power supply system has an important impact on improving the comfort of the user when using the vehicle. Especially for vehicles with high-end configuration, the power consumption configuration is very rich, but not all electrical appliances have voltage stabilizing components. The stability and comfort of electrical funct...
