AI Technical Summary
Existing electric four-wheel drive systems' torque distribution strategies cannot meet the comprehensive performance requirements of hybrid electric four-wheel drive systems, especially in terms of balancing power, economy, and drivability.
The total electric drive torque is determined based on the vehicle torque and input torque. Combined with vehicle operating parameters and preset strategy priorities, the electric drive distribution ratio is determined from multiple torque distribution strategies. The torque transfer conditions of steady state, over-limit and parking are considered, the front and rear electric drive torques are updated, and proportional filtering constraints are introduced to ensure the smoothness of torque distribution.
The hybrid electric four-wheel drive system achieves smoothness and power responsiveness in different driving scenarios, meets comprehensive performance requirements, and ensures the smoothness and power of vehicle driving.
