Embodiment Construction

[0088] In terms of function, the test bench mainly consists of the following parts: drive motor, motor driver and controller, load dynamometer and its controller, and sensor data acquisition part.

[0089] The development of this test bench is for the development of electric vehicles. Therefore, the test environment and functional analysis of the test bench need to be included in the entire simulation system engineering of electric vehicles. The present invention selects AMESim software to complete the simulation model building link. The AMESim software platform contains more than 3,500 special-purpose models from a wide range of application fields. According to the requirements of the present invention, they can be used to build physics-based system models, so that the built-up pure electric vehicle model can reflect real vehicle dynamics more accurately. academic characteristics. This test bench adopts the hardware-in-the-loop idea, and the vehicle environment is placed in ...

Abstract

The invention discloses a torque control method for a hub motor system and a check rack used in the torque control method, belongs to the technical field of electric vehicles, and aims to realize the torque control method for the hub motor system and the check rack used in the torque control method, and the method is used for embedding a hub motor driving hardware system into a simulation environment of various vehicles and various complicated road traveling conditions and testing the performance of the hub motor driving system. The method comprises the following steps: a complete vehicle model building and road condition simulation part, a load part, a measurement part and a driving motor module and motor controller part. The method is relatively low in cost, relatively low in fund, manpower and site input and relatively convenient for motor parameter matching, data obtaining and complicated road condition simulation, removes the cost and danger of real vehicle testing, shortens the development cycle, and facilitates research on performance of the driving motor system and power performance of the electric vehicles.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles. Background technique [0002] Today's energy crisis and environmental pollution have become hot issues of global concern and are being resolved. At present, traditional vehicles mainly rely on oil as power, resulting in a sharp increase in energy consumption. At the same time, the exhaust gas emitted by vehicles causes environmental pollution. Therefore, new energy vehicles are widely accepted by society. Attention from all walks of life, countries and even major automobile manufacturers are committed to the development and application of new energy vehicles. Among them, the electric wheel-type pure electric vehicle adopts the hub motor technology, especially the four-wheel hub motor drive, so that the driving force of the four wheels of the vehicle is independently controllable, the power control of the vehicle is more flexible and convenient, and the drive of each electric wheel is re...
