Electric car road testing system and method

Abstract

The invention relates to an electric car road testing system, which is characterized in comprising a first collection unit, a second collection unit and a central processing unit, wherein the first collection unit comprises a current sensor, a voltage sensor, an A / D signal conversion module, a data reading, writing and storage module, a display module, a first wireless signal transmission module,a Hall sensor and an adding counter; the second collection unit comprises an active infrared intrusion detector, a lithium battery and a second wireless signal transmission module. The invention alsorelates to an electric car road testing method which is characterized in comprising the following steps that: 1) parameter setting; 2) system self-inspection; and 3) parameter detection. The electriccar road testing system is scientific and reasonable in design, and can carry out real-time dynamic and automatic detection on an electric car driving road condition, and continuous parameter recording is realized.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and relates to an electric vehicle road running detection device, in particular to an electric vehicle road test system and method. Background technique [0002] During the riding process of electric vehicles, road tests are required, which generally include vehicle speed, voltage, current, acceleration and steering angle, etc. [0003] At present, the road test instruments installed on electric vehicles sold on the market can only perform instantaneous speed detection, and cannot realize continuous recording of the speed of electric vehicles, and the recorded real-time speed values ​​have deviations, and cannot perform speed verification and detection. It is easy to cause misjudgment of riders during riding, which affects riding safety. [0004] By searching the published patent documents, no published patent documents identical to the present patent application have been found. Contents of t...
