Abstract

The invention provides a range extender control method and device and electronic equipment, and relates to the technical field of vehicles. The range extender control method comprises the steps that firstly, after a vehicle control unit detects that actual operation parameters of a range extender exceed a set operation threshold value, the difference value between the actual operation parameters and the operation threshold value is determined, and then the vehicle control unit can determine the limiting coefficient of the actual operation parameters according to the obtained difference value. And finally, the vehicle control unit can send an operation parameter control instruction to the range extender according to the limiting coefficient. Therefore, the range extender can be prevented from being damaged due to over-power operation, and safety accidents are avoided at the same time.

Description

【Technical field】 [0001] The present application relates to the technical field of vehicles, in particular to a range extender control method, device and electronic equipment. 【Background technique】 [0002] A range-extended electric vehicle is a type of electric vehicle that can be driven by a range extender to increase the driving range when the battery power is insufficient. The range extender mainly includes two parts: the engine and the generator. The engine can drive the generator to rotate through coupling with the generator, and the generated electric energy can continue to power the car. [0003] During the process of the vehicle controller controlling the operation of the range extender, due to the differences in the selection of components for different range extenders, or the instability of the control process, there may be differences between the actual operating parameter values ​​of the range extender. An inconsistent condition indicated by a control instruct...
