“…The researches mentioned above all have achieved excellent results and improved the stability and maneuverability performance of the SBW system in some respects. However, from the simulation results of the papers [11][12][13], the performance of interference rejection is not reflected. Even though the control scheme presented in paper [14] has pretty good robustness, the RBFNN is a relatively complicated control algorithm strongly depending on the training samples which are impossible to cover all the driving conditions.…”

A control strategy based on LQG/LTR theory for steer-by-wire (SBW) system is proposed in this paper. Firstly, the models of the SBW system and the whole vehicle are constructed. Secondly, the control strategy of LQG for SBW system is proposed, in which the LTR is utilized to eliminate the effect from the Kalman filter. Thirdly, simulations based on the co-simulation platform of MATLAB/Simulink and Carsim are performed with the proposed control strategy to identify its performance. At last, field experiments are conducted to further verify the feasibility of the proposed control strategy in real application. The simulation and experiment results indicate that the proposed control strategy has good stability, robustness and feasibility in real application, and is more effective in practical application of SBW system. steer-by-wire (SBW), LQG/LTR, stability control, robustness, Kalman filter Citation:Zhang H, Zhao W Z.

“…Moreover, based on some experiments, they showed that the controller improves vehicle's stability in the case of driving on low-friction roads where behavior of the vehicle is different from the driver's input command. Yao (2006) transformed various driving scenarios, such as experiencing different steering feel, returnto-center performance, and fast and accurate wheel angle tracking based on driver's input into the control problems. Modern control techniques, system parameter identification, and state variable estimation were used to execute these scenarios.…”

In this paper, road forces on tire are exerted on driver's hands via an equivalent torque applied to the steering wheel using a hardware-in-the-loop method to analyze the effect of steering torque feedback in vehicle handling. An electrical torquefeedback steering system is used for experimental validation. A 14-degree-of-freedom vehicle dynamic model, including engine, tire, and steering system mechanism are simulated. The required inputs such as throttle angle, brake demand, and steering wheel angular position are transmitted to the computer via an I/O interface card. Tire forces and steering gear torque are solved. This torque is then sent via an I/O interface card to a DC motor connected to the steering shaft. All equations are solved in real time. To investigate the influence of torque feedback on vehicle handling, several experiments are executed on 25 users. For this purpose, an experimental protocol is defined. In the experiments, the users had to drive along a specific path with constant speed using the designed electrical torque-feedback steering system. During the tests, the driving pattern of each user was recorded and the simulator's instantaneous position was compared with its desirable value. The results show that the torque feedback improved the driver's perception from the surrounding environment and enables her/him to handle the vehicle satisfactorily.

“…The EPAS has been used to design an active disturbance rejection control to reduce the steering torque exerted by the driver due to external side wind force. Other automotive researchers as stated in [8,9] focused on the safety system of steering system using steerby-wire technology. This technology is mainly invented from an aircraft system known as fly-by-wire.…”

In this study, 2 DOF mathematical models of Pitman arm steering system are derived using Newton's law of motion and modeled in MATLAB/SIMULINK software. The developed steering model is included with a DC motor model which is directly attached to the steering column. The Pitman arm steering model is then validated with actual Pitman arm steering test rig using various lateral inputs such as double lane change, step steer, and slalom test. Meanwhile, a position tracking control method has been used in order to evaluate the effectiveness of the validated model to be implemented in active safety system of a heavy vehicle. The similar method has been used to test the actual Pitman arm steering mechanism using hardware-in-the-loop simulation (HILS) technique. Additional friction compensation is added in the HILS technique in order to minimize the frictional effects that occur in the mechanical configuration of the DC motor and Pitman arm steering. The performance of the electronically actuated Pitman arm steering system can be used to develop a firing-on-the-move actuator (FOMA) for an armored vehicle. The FOMA can be used as an active safety system to reject unwanted yaw motion due to the firing force.
