Zero calibration method, device, vehicle and medium based on extended-range power generation system

Abstract

The embodiments of the present invention disclose a zero-position calibration method, device, vehicle and medium based on an extended-range power generation system. The method includes: detecting the current working state of the vehicle in which the range-extending power generation system is located according to a zero-position calibration request for the range-extending power generation system; if the current working state satisfies a preset zero-position calibration condition, starting a The extended-range engine is used to calibrate the zero position of the extended-range power generation system according to the working offset parameters of the extended-range generator in the extended-range power generation system driven by the extended-range engine. The technical solutions provided by the embodiments of the present invention realize the automatic calibration of the zero position on the extended-range power generation system, without the need to manually adjust and record the corresponding zero position when assembling the extended-range power generation system, improve the assembly efficiency of the extended-range power generation system, and avoid manual labor. Adjust the installation deviation of the extended-range power generation system at the zero position, ensure the accuracy of the zero position calibration on the extended-range power generation system, and improve the power supply performance consistency of the extended-range power generation system.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of extended-range power generation systems, and in particular, to a zero-position calibration method, device, vehicle, and medium based on a range-extended power generation system. Background technique [0002] With the shortage of energy and the deterioration of the environment, the vehicle equipped with the extended-range power generation system can use the extended-range power generation system to charge the entire vehicle battery when the vehicle battery is consumed to a certain extent, so as to extend the cruising range of the vehicle, so as to prolong the battery life of the vehicle. More and more attention has been paid to it. At this time, the reliability and safety of the extended-range power generation system for charging the vehicle battery is particularly important. [0003] Existing range-extending power generation systems such as figure 1 As shown, it usually includes an ...

Problems solved by technology

[0004] The manually adjusted zero position in the existing range-extending power generation system cannot be easily changed after being written into the range-extending generator controller. The rectification operation performed by the written zero position will also cause a deviation between the actual given current signal and the magnetic field signal, so that the range-extending generator lags behind the output or cannot output the best torque performance under the corresponding torque

At the same time, when installing the range-extending power generation system on each vehicle, it is necessary to manually adjust the zero position and write it into the range-extending generator controller, which consumes a lot of installation time and makes the installation efficiency low
