Abstract
Taking three pure electric vehicles as the research object, the energy consumption and acceleration performance of the electric vehicle are tested and evaluated through the use of the intelligent unmanned test platform of the whole vehicle, which ensures that the accurate and high-speed test of the road test can be realized on the basis of no driver in the vehicle. For the electric vehicle energy consumption test, the intelligent unmanned test platform is used for road test, which not only effectively avoids the driver driving the test vehicle for a long time, but also ensures the accuracy and reliability of the test data. According to the test results, the acceleration response and energy consumption test results of three pure electric vehicles are analyzed and evaluated.
Highlights
Taking three pure electric vehicles as the research object, the energy consumption and acceleration performance of the electric vehicle are tested and evaluated through the use of the intelligent unmanned test platform of the whole vehicle, which ensures that the accurate and high-speed test of the road test can be realized on the basis of no driver in the vehicle
Will test vehicles according to the testing personnel in remote console writing good tests by wireless transmission way to send to the robot controller, through the ground base station positioning, real-time control of the car's steering robot along a given path, throttle robots will test vehicle speed accelerate to 45 km/h, with gear taxiing to speed to 40 km/h, the gas pedal robots in 500 ms trample accelerator pedal and keep to 100% opening to record the speed of 100 km/h time, repeat the test three times
In the test vehicle load conditions, a pure electric vehicle energy consumption test, specific implementation is as follows: In remote console will test vehicles according to test writing good tests by wireless transmission way to send to the robot controller, through the ground base station positioning, real-time control of the car's steering robot along a given path, throttle robots will test vehicle speed up to 100 km/h, and keep the speed ring lane five laps at high speed(8km high speed loop).Record the driving time and the voltage and current released during the test
Summary
The acceleration response and energy consumption test of pure electric vehicles should be carried out in a professional vehicle test site. Long straight dry and flat asphalt pavement should be selected in the test site to ensure that the intelligent unmanned test platform has a long distance to slow down and stop the vehicle after the completion of acceleration test. The longitudinal slope of the test area shall not be less than 1%, and the transverse slope shall not exceed 1%.
