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

Abstract

The embodiment of the invention discloses a zero calibration method and device based on an extended-range power generation system, a vehicle and a medium. The method comprises the steps of detecting acurrent working state of a vehicle where the extended-range power generation system is located according to a zero calibration request for the extended-range power generation system; and if the current working state meets a preset zero calibration condition, starting an extended-range engine in the extended-range power generation system, and calibrating the zero position of the extended-range power generation system according to a working offset parameter of the extended-range power generator in the extended-range power generation system under the driving of the extended-range engine. The embodiment of the invention provides a technical scheme, the automatic calibration of a zero position on the extended-range power generation system is realized; the corresponding zero position does not need to be manually adjusted and recorded when the extended-range power generation system is assembled, the assembly efficiency of the extended-range power generation system is improved, meanwhile, theinstallation deviation of the extended-range power generation system when the zero position is manually adjusted is avoided, the accuracy of zero position calibration on the extended-range power generation system is guaranteed, and the power supply performance consistency of the extended-range power generation system is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of range-extended power generation systems, and in particular to a zero 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, when the vehicle battery is depleted to a certain extent, the vehicle equipped with the extended range power generation system can use the extended range power generation system to charge the vehicle battery to prolong the cruising range of the vehicle, so that the 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-extended power generation systems such as figure 1 As shown, it usually includes a range-extending engine 1, a range-extending generator rotor 2, a bolt 3 connecting the range-extending gener...

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
