Method for realizing finished automobile parameter calibration based on automobile-mounted wireless intelligent terminal

Abstract

The invention relates to a method for realizing vehicle parameter calibration based on a vehicle-mounted wireless intelligent terminal. On the vehicle wireless intelligent terminal corresponding to the vehicle communication number of the calibration parameters; the vehicle wireless intelligent terminal parses the parameter calibration file after receiving it, and then sends the data to the vehicle controller through the body CAN network according to the CAN communication protocol; the vehicle controller The parameter calibration is completed after receiving the data from the vehicle-mounted wireless intelligent terminal. The present invention provides a complete set of solutions for the parameter calibration of pure electric buses, and provides a high-efficiency and low-cost implementation method for the maintenance and upgrading of vehicle parameters; through the present invention, the vehicle can be quickly and uniformly calibrated parameters, save time and effort, and reduce the requirements for people.

Description

technical field [0001] The invention relates to the technical field of pure electric passenger cars, in particular to a method for realizing vehicle parameter calibration based on a vehicle-mounted wireless intelligent terminal. Background technique [0002] Pure electric bus, as an energy-saving and pollution-free "zero-emission" vehicle, has the advantages of high efficiency, environmental protection, energy saving, low noise, zero pollution, etc. It is currently the mainstream new energy vehicle technology and a future development trend of vehicles. . Due to these advantages, the country has been increasing its efforts to promote pure electric vehicles in recent years. [0003] After several years of rapid growth, the number of pure electric buses put into the market is huge and widely distributed. Due to geographical differences, the same vehicle needs to be matched with different technical parameters when operating in different regions, and some of them need to be ch...

Problems solved by technology

[0003] After several years of rapid growth, the number of pure electric buses put into the market is huge and widely distributed. Due to geographical differences, the same vehicle needs to be matched with different technical parameters when operating in different regions, and some of them need to be changed according to the actual operating conditions. The current The problem is that after-sales service personnel need to go to the site to manually modify one by one through the computer, which is time-consuming and laborious, and there may be omissions, resulting in different technical parameters of the same batch of vehicles
