Debugging method, system and device for new energy vehicle, and storage medium

Abstract

The invention discloses a debugging method of a new energy vehicle, which comprises the following steps: selecting a target relationship function from a preset relationship function set according to afunction selection instruction, each relationship function in the relationship function set being a relationship function which takes a torque rise step length as a dependent variable, takes an accelerator pedal opening degree as an independent variable and has an undetermined parameter; completing numerical value setting of each undetermined parameter in the target relation function according tothe parameter setting instruction; and debugging the new energy vehicle, and in the debugging process, selecting the torque rise step length based on the target relation function which completes thenumerical value setting of each undetermined parameter. By means of the method, the torque step length can be set conveniently and efficiently, and then the development efficiency of new energy vehicles can be improved. The invention further provides a debugging system and device for the new energy vehicle and a storage medium, and the corresponding technical effects are achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle debugging, in particular to a debugging method, system, equipment and storage medium for new energy vehicles. Background technique [0002] With the adjustment of the energy structure and the advancement of energy security, there are more and more styles and sales of new energy vehicles. In the development process of new energy vehicles, torque control is a relatively complicated project. Through the change of torque control, different driving experiences can be obtained. [0003] In the development process of traditional new energy vehicles, the calibration of torque control involves multiple look-up tables. The process of target torque look-up table and torque step calibration process requires a lot of repetitive work. This part of the work is generally performed by the vehicle controller. Specifically, the torque step refers to the difference between the torque command output by the vehicle co...

Problems solved by technology

However, the calibration process of this method takes a long time. Generally speaking, the torque step size of the look-up table has at least 25 calibration points, which makes it very troublesome to set the torque step size.

Moreover, in the process of vehicle development, the table needs to be adjusted continuously, and the repetitive workload is large, which is not conducive to improving development efficiency
