Embodiment Construction

[0011] The smart alternator for automobile is connected with the wiring harness of the automobile central processing unit through a connector. When the intelligent alternator is working, it will feed back the working status information to the automobile central processing After the working state information of the alternator is fed back to the smart alternator through the direct current control signal (DC for short), and the set voltage of the working point of the smart alternator is controlled, so as to realize the intelligent control of the smart alternator. The above-mentioned connectors include at least the L terminal that receives external excitation and lights up the meter charging indicator, the FR terminal that feeds back the working status of the automotive intelligent alternator to the automotive central processor, and the C terminal that receives the DC control signal of the automotive central processor. Terminals, in order to realize the communication between the in...

Abstract

The invention relates to a method for controlling an intelligent alternating current generator for a vehicle and aims to solve the technical problems of design complexity, high cost and low control reliability of the conventional like products. The intelligent alternating current generator is connected with a wire harness of a vehicle electronic control unit (ECU) through a plug connector, and when the intelligent alternating current generator works, working state information is fed back to the vehicle ECU. The method is characterized in that the vehicle ECU receives the working state information of the intelligent alternating current generator, a direct current (DC) control signal is fed back to the intelligent alternating current generator, and the set voltage of a working point of the intelligent alternating current generator is controlled. The method is simple in control mode and high in control accuracy, the oil consumption of the vehicle and exhaust gas emission can be reduced, the structure design of the vehicle ECU can be simplified, cost is reduced, the method is slightly influenced by working state frequent switching of the alternating current generator, reliability is improved, and the method can be applied to control over the intelligent alternating current generator for the conventional vehicle.

Description

technical field [0001] The invention relates to an automobile alternator, in particular to a control method for an automobile intelligent alternator. Background technique [0002] The smart alternator for automobiles is an energy conversion component that follows the principle of electromagnetic induction and the law of energy conservation. It is used to reduce fuel consumption and exhaust emissions of automobiles, and make the smart alternator for automobiles work in the optimal working condition, which is important for improving efficiency. good choice. Compared with ordinary automotive alternators, the intelligent alternator for automobiles can reduce the energy input requirements from the automobile engine, so it has a certain energy-saving effect. [0003] Existing smart alternators for automobiles generally use FR to feed back the working status of the alternator to the automotive central processing unit (referred to as ECU). The width control signal (referred to as ...
