AI Technical Summary
Existing regenerative braking methods cannot maintain lateral stability of electric semi-trailer trucks during cornering braking conditions, and existing control strategies suffer from sluggish response and insufficient stability under extreme conditions, making it difficult to improve regenerative braking efficiency.
An improved Dugoff tire model and SRCKF model were constructed based on the road adhesion coefficient. Combined with the vehicle dynamics model, the braking force distribution was adaptively switched through electromechanical coupling braking and energy recovery strategies to ensure the lateral stability and energy recovery efficiency of the vehicle under different road conditions.
It realizes the adaptive switching of braking energy recovery strategy for electric semi-trailer trucks under different road surface adhesion coefficients, ensuring the comprehensive optimization of braking energy recovery and lateral stability during vehicle operation, adapting to different road conditions and rationally distributing braking force.
