Embodiment Construction

[0029] The method for reducing the generator load and the readable storage medium proposed by the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that, the accompanying drawings are all in a very simplified form and in inaccurate scales, and are only used to facilitate and clearly assist the purpose of explaining the embodiments of the present invention. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, each drawing needs to show different emphases, and sometimes different scales are used.

[0030] For a vehicle, the engine provides kinetic energy to the generator so that the generator can generate electricity. When the generator is not generating electricity, the torque resistance (load) of the engine is reduced....

Abstract

The invention provides a method for reducing engine load and a readable storage medium. When the pedal demand torque is greater than the torque threshold, the generator voltage is controlled to drop from the target voltage to the first calibration value, so that the generator is not generating power State, and then to reduce the load of the engine; by controlling the maximum excitation current sent to the generator to the second calibration value if the target electrical appliance of the vehicle is turned on in the engine idle state, so that the The generating current of the generator is reduced, thereby reducing the load on the engine. In this way, the problem that the prior art cannot effectively reduce the load of the vehicle engine is solved.

Description

technical field [0001] The present invention relates to the technical field of automobiles, and in particular, to a method for reducing engine load and a readable storage medium. Background technique [0002] At present, in many automobile OEMs, the 12V generators mounted on the engine gear train are upgraded from the previous ordinary generators to intelligent generator controllers (IGC, intelligent generator controller) for complete vehicle projects equipped with gasoline engines. The power sensor (EBS) communicates with the electronic control unit (ECU, Electronic Control Unit) through the LIN line. The ECU can generate electricity on demand according to the SOC feedback of the EBS: when the battery power is insufficient, the ECU increases the target voltage through LIN to allow the generator to generate electricity; when the battery power is sufficient, the ECU also transmits commands to the IGC through LIN to reduce the target voltage Power generation voltage, so that ...
