Embodiment Construction

[0037] Hereinafter, the present invention will be specifically described based on the drawings showing the embodiments of the present invention.

[0038] figure 1 It shows the electrical connection relationship between the power generation control device and other equipment in the car according to an embodiment of the present invention.

[0039] see figure 1 , in this embodiment, the power generation control device 100 is coupled with the engine controller 200 and the vehicle instrument 500 via the CAN bus on the one hand, and coupled with the generator regulator 300 and the battery state monitor 400 via the LIN bus on the other hand. Thus, the power generation control device 100 can obtain the status information of the generator, the engine and the storage battery, and generate appropriate control commands according to the status information to realize an optimized power generation strategy. These control commands will be output to the engine control system via the CAN bus a...

Abstract

The invention relates to automobile energy techniques, in particular to a power generation control device and a power generation control method for automobiles. The power generation control device for automobiles comprises a communication interface and a processing unit, wherein the communication interface is responsible for communication with a power generator adjustor, an engine controller and a storage battery state detector, and the processing unit is used for generating control orders according to state information provided by the power generator adjustor, the engine controller and the storage battery state detector to enable a power generator to generate corresponding electric energy and a motor to make corresponding torque compensation. According to the power generation control device and the power generation control method, power generating voltage of the power generator is increased under a certain braking condition, and accordingly more vehicular kinetic energy can be converted into electric energy to be stored in a storage battery, and economical efficiency of the vehicle can be improved.

Description

technical field [0001] The invention relates to automobile energy technology, in particular to a power generation control device and method for automobiles. Background technique [0002] The vehicle power supply system is mainly composed of accumulator (battery), energy converter (generator), starter and control unit. When the engine is running, it will drive the generator to generate electricity, supply power to the electric load of the car and charge the battery. For example, if the electrical current of the automobile electrical system is greater than the power supply current of the generator, the battery will be discharged to make up for the insufficient current. On the contrary, if the electrical current of the automobile electrical system is less than the power supply current of the generator, the current difference Part of it flows into the battery as charging current for the battery. [0003] In conventional vehicles with 12V electrical systems, the generated volta...
