To address the issue of understeer,difficulty in control effect calibration,complex controller design and difficulty in engineering application,this article proposed a novel approach to vehicle handling control by enabling adaptable rear wheel steering and braking intensity.Employing nonlinear model design and a feedforward/feedback structure,this method can adjust control intensity according to design parameters,allows for improving the vehicle's center of mass sideslip angle according to expectation and enhancing yaw response speed.In addition,the approach also accommodates understeer mitigation and fuel economy optimization.In addition,the proposed method also has other advantages such as high accuracy,small computational complexity,no need for vehicle sideslip angle estimation,and ease of calibration.A method for vehicle handling tuning based on adjustable parameters is also provided.
