Light Electric Vehicle Driving Process Test Analyzer

Abstract

The invention discloses a testing analyzer for the driving process of a light-weight type electric vehicle, and relates to a testing instrument of the electric vehicle. The testing analyzer comprises a sensor group, a signal acquisition mechanism and a signal analysis system, wherein the sensor group is used for acquiring original data in the driving process of the electric vehicle to be tested; the signal acquisition mechanism is used for receiving the original data acquired by the sensor group, carrying out data processing on the original data and carrying out storage and display on the processed data; the signal analysis system is used for receiving the data sent by the signal acquisition mechanism, carrying out analysis and processing on the data and outputting a testing result. The testing analyzer disclosed by the invention has the advantages that unified acquisition, analysis and recording can be carried on the data of the light-weight type electric vehicle in the driving process, and various testing results of the electric vehicle in the driving process can be output, so that the observation of a vehicle tester is convenient.

Description

technical field [0001] The invention relates to a testing instrument for an electric vehicle, in particular to a testing instrument for the driving process of the electric vehicle. Background technique [0002] Current light-duty electric vehicles (electric bicycles, electric motorcycles, electric tricycles, electric mini-cars, etc.) do not have an on-board communication bus, so motor controllers, alarms, instrument panels and other equipment are directly connected by signal lines. When testing the road performance of vehicles, light electric vehicle companies generally adopt the method of purchasing instruments or test modules for various signals, such as ammeters (current recorders), GPRS speed modules, voltmeters, tachometers, and slope meters. , Thermometer, etc. This method not only has a high cost, but also has some technical rationality problems: (1) Some instruments do not have a recording function. Even if there is a recording function, the data collection of each ...

AI Technical Summary

Problems solved by technology

This method not only has a high cost, but also has some technical rationality problems: (1) Some instruments do not have a recording function. Even if there is a recording function, the data collection of each instrument is not synchronized, which brings errors to performance analysis

(2) For vehicle performance analysis, signal acquisition is required to have high real-time and sampling frequency, and it is difficult to make all the instruments purchased have this function

(3) Since the sensors and corresponding instruments are distributed in different parts of the vehicle, it is not convenient for the tester to observe at the same time

(4) Since the instruments are not designed for electric vehicles, they are independent of each other, cannot work together, and cannot directly reflect the driving status of the vehicle, such as speed ratio calculation, slope calculation, power and efficiency analysis, etc.

These problems bring difficulties to the performance analysis of light electric vehicles during driving
