Abstract: This paper systematically analyzes the testing requirements for distributed drive vehicles in the new energy automotive sector. Addressing challenges such as the difficulty in reproducing high-risk scenarios and long testing cycles, it proposes an innovative testing platform solution for distributed electric drive systems based on a virtual four-wheel-drive architecture. Utilizing dynamometer torque distribution technology, this platform can simulate extreme conditions—such as high-speed cornering and ice surface slippage—on the electric drive assembly test bench. This enables a more comprehensive and effective validation of the system′s dynamic performance boundaries, providing robust support for the safety and reliability evaluation of distributed electric drive systems and the formulation of relevant industry standards.
