AI Technical Summary
In existing technologies, the power systems of hybrid and amphibious vehicles cannot effectively adjust the maximum output torque under different driving conditions, resulting in limited power performance. In particular, the power demand is greater when driving on water than in land mode, which limits the load on the transmission system.
By referencing the change in the torque converter coefficient K and the input-output speed ratio, the upper limit of the maximum output torque is dynamically adjusted. By utilizing the characteristics of the torque converter, dynamic adjustment is achieved to meet the power requirements of different driving conditions.
It achieves a balance between the safety and power performance of the power system under different driving conditions, fully utilizes the vehicle's power performance, and avoids the limitations of traditional fixed-limit methods.
