Abstract

The invention discloses an electric vehicle driver simulation test platform, which comprises a mechanical system and an electric appliance system, wherein the mechanical system comprises a permanent magnet synchronous motor and a controller thereof, a load DC motor and a speed regulator thereof; a signal measurement carrier is arranged between the mechanical system and the electric appliance system, and comprises a torque / rotation speed sensor, a power analyzer, a temperature sensor, a voltage and current sensor and its peripheral circuits; and a heavy current part in the electric appliance system comprises a switching power supply cabinet, a four-quadrant rectifier, a DC motor and an electric vehicle driving system, and a weak current part comprises a main control system, a communicationline, a control panel, a power analyzer and an upper computer. The tester can set load variations through programming, so as to verify whether coping algorithms of a driver are effective under variousroad situation environments, HDT2.0PC software records all the parameters of the tested driver and loads completely by means of a CAN bus, thus various analyses is facilitated, and the test is simpleand reliable.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle driver simulation test platform. Background technique [0002] Electric vehicles have significant features such as high efficiency, energy saving, low noise, and zero emissions, and have become a clean, efficient and sustainable means of transportation in the 21st century. The performance of the electric vehicle drive determines the power performance, braking performance, stability, safety and economy of the electric vehicle. [0003] Magtrol Corporation of the United States is a global leading brand in the dynamometer industry. Its products are mainly for testing frequency converters and servo drives.
