To enhence the rationality of the vehicle torque control strategy for distributed-drive vehicles, this paper proposes a control strategy based on an optimize torque distribution strategy to reduce the operating conditions of synchronous zero-crossing of the front and rear dual motors, thereby improving issues such as vehicle resonance and impact. In addition, for typical operating conditions such as rapid acceleration with a large throttle depression when the battery has low power, a torque following filtering optimization control method is proposed to improve the problem of slow vehicle acceleration caused by insufficient system capacity. The test results show that the proposed zero-crossing control strategy effectively optimizes the problem of vehicle impact caused by the synchronous zero-crossing of dual motors; the proposed vehicle torque filtering optimization control method increases the vehicle's acceleration at a characteristic point by 0.62 m/s2 in a power-feedback state, while ensuring driving comfort.
