Embodiment 1

[0037] The first embodiment of the present invention proposes a method for controlling an automobile generator, which can be applied to, for example, the automobile generator control system described in the second embodiment. The automobile control system includes an information detection element and a control unit, and the control unit includes Engine controller and generator regulator.

[0038] figure 1 It is a schematic flowchart of a method for controlling an automobile generator according to the first embodiment, refer to figure 1 , the method includes the following steps:

[0039] Step S101 , acquiring the charge and discharge information of the vehicle battery and the duty ratio information of the generator.

[0040]Specifically, in the step, the charge and discharge information of the car battery and the duty cycle information of the generator can be obtained through the information detection element. More specifically, the information detection element can include a...

Embodiment 2

[0068] The second embodiment of the present invention proposes a generator control system, figure 2 For a schematic structural diagram of a generator control system according to the second embodiment, refer to figure 2 , the system includes:

[0069] The information detection element 1 is used to obtain the charge and discharge information of the automobile 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 charge and discharge information and the duty cycle information;

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

Abstract

The invention relates to a generator control method and a system thereof. The method includes obtaining the charging and discharging information of a car battery and the duty ratio information of the generator through an information detection element, and then jointly realizing the according to the generator controller and the generator regulator. The charge and discharge information and duty cycle information control the operation of the automobile generator to realize the voltage regulation of the whole vehicle; wherein, if the automobile battery is in a discharge state and the duty cycle of the generator is greater than a preset ratio threshold, the generator excitation current limit is lifted. The invention realizes the stable voltage of the whole vehicle by adjusting the generator control logic and the setting of main parameters in the regulator, and avoids adding a DC / DC converter.

Description

technical field [0001] The invention relates to the technical field of automobile generator control, in particular to a generator control method and a system thereof. Background technique [0002] With the rapid development of automotive electronic technology, traditional electronic appliances and intelligent network technology are changing with each passing day, and a large number of electrical systems and control modules have increased. The vehicle power supply system to maintain the vehicle voltage stability has an important impact on improving the comfort of the user using the vehicle. Especially for high-end vehicles, the power configuration is very rich, but not all electrical appliances have voltage regulator components, and the stability and comfort of electrical functions have put forward high requirements for the voltage of the whole vehicle. If the voltage of the whole vehicle is pulled down instantaneously, it may cause some electrical devices to reset and resta...
