Vehicle chassis coordinated control strategy based on model predictive control method

With the chassis electronic technology evolving, the chassis control technologies for active safety have been widely used. Through active intervention in the vehicle horizontal and vertical dynamics, electronic control systems can improve vehicle stability and handling greatly, thereby ensuring the safe driving of vehicles. This article will coordinate active steering, active braking and active suspension based on model predictive control and logic control to achieve the coordination among the horizontal and vertical dynamics, and further enhance the vehicle´s active safety level. We also conducted simulation, and result shows that the control strategy can effectively improve vehicle active safety.
