Therefore, the vehicle testing and calibration periods are shortened, and the electric vehicle development risk and cost are reduced.

Description

technical field [0001] The invention relates to a test platform, in particular to an AMT automatic transmission power transmission system assembly test test platform. Background technique [0002] Pure electric vehicles have the characteristics of high efficiency, energy saving, and terminal zero emission, and are an important way to solve the energy crisis and environmental pollution. However, pure electric vehicles are limited by the energy density of the battery and the efficiency of the drive system, the cruising range is short, and the charging time is long, which restricts the promotion and application of pure electric vehicles. Therefore, selecting and matching the key parts of the power transmission system, and selecting appropriate shifting and control strategies can improve the efficiency of the drive system and effectively extend the cruising range of pure electric vehicles, which will improve the performance of vehicles in the future. plays an important role in ...
