Design of an Active Gate to Control the Passenger Vehicle

Abstract

A lot of research is being done on the movement of vehicles, especially at high speeds, to maintain safe and stable driving on highways. To reduce traffic congestion, reduce fuel consumption, reduce pollution, and increase safety. It was proposed in the current work to install an internal air duct in the vehicle that is controlled by the left and right entry gates, as well as gates to control the opening and closing of these gates, to improve the aerodynamic performance and balance of the vehicle, particularly in turns. A mathematical model was developed. The model's outputs are coupled to the control system for optimal vehicle performance while driving. A review of the various control algorithms was presented, followed by a discussion of the different control strategies (LQR – PID -ANNs) study to control the steering angle and the closing and opening ratio of the gate at various driving speeds. The simplified car model was run and used in the proposed control algorithm, and then the car model was modelled and simulated using the MATLAB software. In all steering angles, the LQR-based control unit responds quickly and efficiently.
