Research on the Control Method of Vehicle Driving Mode Switch
With the development of automobile science and technology,automobile intelligence and interconnection have become a trend.The driving mode can meet the special needs of users by adjusting vehicle suspension,power and steering,and its control method affects user experience and vehicle performance,so it is of great significance to study the control method of automobile driving.In this paper,a vehicle driving mode management system is proposed.When the driving mode is allowed to change,the user can operate the mode switch to switch the vehicle driving mode,including normal,economic,sports and mountain modes.In terms of function realization,the switch actuator is connected to the body controller,mode switching is arbitrated in the transmission controller,and the body,engine and transmission controller,instrument and vehicle module cooperate with each other to achieve the function.In this paper,the functional design requirements and driving mode switching strategy of each controller are described in detail,including function opening logic,function judgment logic and function execution logic.Finally,it is concluded that the proposed driving mode switching control method has advantages of strong stability,high reliability and closed-loop control.
