Problems solved by technology
[0004] At present, the whole vehicle factory adopts the closed-loop control of the whole vehicle for the control of the generator, but the signal communication of the generator is disconnected, the generator enters the mode of not generating power, and there is no emergency treatment measure; No power generation, you need to go to the repair shop to repair the generator, there is no simple and effective measure to detect and judge, the false positive rate is high, wasting time and money

Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:
[0028] like figure 1 and 2 The shown control system of the automobile generator, which includes an engine control module 1, a body central control module 2, a power sensor 4 and a generator 8;
[0029] The power sensor 4 is used to collect the working condition information of the battery 5, and send the working condition information of the battery 5 to the engine control module 1 through the vehicle body central control module 2;
[0030] The engine control module 1 is used to judge whether the power of the battery 5 is in a full state by using the working condition information of the battery 5; when the power of the battery 5 is not in a full state, the engine control module 1 sends a generator control signal to the generator 8, and the generator 8. According to the generator control signal combined with the generator control progr...

The invention discloses a control system of an automobile generator, which is characterized in that an electric quantity sensor is used for collecting working condition information of a storage battery and sending the working condition information of the storage battery to an engine control module; the engine control module is used for judging whether the electric quantity of the storage battery is full or not according to the working condition information of the storage battery; when the electric quantity of the storage battery is not in a full state, the engine control module sends a generator control signal to the generator, and the generator outputs corresponding power supply voltage and current according to the generator control signal in combination with a generator control program so that the storage battery can be charged to the full state. The signal value of the generator control signal and the power supply voltage and current of the generator correspondingly form a matrix relationship, and the matrix relationship is set in a generator control program; and if the generator does not receive the generator control signal within the preset time or the generator control signal wiring is disconnected, the generator enters a default control program. The method is stable in control, can reduce the oil consumption of the engine, and is convenient for user detection.
Description
technical field [0001] The invention relates to the technical field of automobile generators, in particular to a control system, a control method and a detection method of an automobile generator. Background technique [0002] The automobile industry is an important pillar industry of the national economy and plays an important role in the development of the national economy and society. With the continuous development of my country's economy and the increase in the demand for automobiles, automobiles are becoming more and more closely related to the economic life of the people. Although more and more customers have their own cars, as the degree of electrification of the car becomes higher and higher, the electrical structure of the whole vehicle becomes more and more complicated. Electrical devices related to vehicle power supply system. [0003] Due to the increasing consumption of non-renewable resources, especially the consumption of petroleum resources, the country's ...
