“…A steer-by-wire (SBW) system eliminates the mechanical connection between the steering wheel and the steering mechanism. Steer-by-wire technology is used to control the steering of a vehicle through electrical signals [7,8]. The steering ratio can be arbitrarily designed, so that the vehicle handling stability and safety are significantly improved [9].…”

The handling stability of tracked vehicles not only affects the handling convenience of drivers but is also an important part of vehicle active safety. A zero-differential steering controller for tracked vehicles with hydraulic-mechanical transmissions was designed in this paper. First, the working principle of the steer-by-wire systems of tracked vehicles was analyzed, and the vehicle speed calculation model was established. Then, the steering dynamics model of the tracked vehicle was established based on the shear stress model. Finally, based on the particle swarm optimization algorithm, the established tracked vehicle steering dynamics model was iteratively solved, and the optimal yaw rate gain 𝐾 𝑟 was calculated in real time and used for vehicle steering control. The steering control simulation model of tracked vehicles was established in MATLAB/Simulink, and the control effect of the designed steering controller was verified by the simulation. The control effect was evaluated by the comprehensive evaluation index of the handling stability. The simulation results showed that the steering controller based on the particle swarm optimization algorithm effectively improved the handling stability of the tracked vehicle and reduced the burden on the driver.INDEX TERMS particle swarm optimization algorithm, steer-by-wire system, tracked vehicle, zerodifferential steering controller

“…Además, la redundancia de medidas no se considera un sobrecoste en el sistema, sino una medida añadida de seguridad, así como una herramienta para la detección de errores en los sensores haciendo uso de herramientas como el filtro de Kalman. En lo referente al método de representación del modelo que rige el sistema Drive-by-wire, las dos técnicas más extendidas son mediante espacios de estado (Halton et al, 2008) y funciones de transferencia (Zhu et al, 2019). El orden de estas representaciones determinará la complejidad de las siguientes etapas de diseño de la arquitectura de control.…”

<p>Este trabajo presenta el modelado y control completo del sistema Drive-by-Wire de un vehículo urbano eléctrico. Dicho sistema comprende el mecanismo de dirección, la aceleración y el freno del vehículo. El modelado se ha realizado empleando funciones de transferencia de bajo orden haciendo uso de modelos de “caja negra”. En lo referente al control, todos los controladores desarrollados son del tipo PID en sus distintas configuraciones. Los actuadores de corriente continua acoplados a la dirección y freno se controlan mediante un sistema de control en cascada mientras que la aceleración está controlada por un sistema de planificación de ganancias. El código del proyecto se encuentra disponible en la plataforma Github. Los resultados obtenidos demuestran la validez de los modelos obtenidos, así como la eficacia de los controladores desarrollados.</p>
