Abstract:
In order to realize the full function test and display strategy verification of the automobile instrument, a simulation test environment is built by using the actual vehicle data. The host computer reads the real data script, and the serial data are sent to the electronic control unit, and then the electronic control unit controls instrument signal to realize instrument function test. The stepper motor is used to drive the sliding rheostat to simulate the oil fuel consumption value of the oil float and realize the simulation of the actual fuel quantity data. Based on win32 platform development data analysis environment, the actual vehicle data extraction analysis is realized to provide data basis for the instrumentation control strategy and display algorithm. A common script protocol is developed according to the source to meet a variety of instrument specifications test requirements. A variety of instrumentation tests show the platform has a good practicality, versatility, and can greatly shorten the LCD instrument research, development and testing cycle.
