“…regarded reducing wheel sliding rate and avoiding motor torque oversaturation as constraints, proposing an adaptive electronic differential strategy based on equal torque distribution. Although the wheel sliding rate was reduced, a more reasonable driving torque distribution method was not adopted, thus the vehicle lateral stability is poor [5,6] . Daya et al used the Ackermann geometry to determine the target speed of each wheel, using closed-loop control to realize the torque distribution of the driving wheels, then, adjusted the speed to achieve the differential effect.…”

To improve the differential performance and lateral stability of distributed drive electric vehicles, this paper proposes an electronic differential control strategy for rear-wheel independent drive electric vehicles based on target torque secondary distribution. Firstly, according to the ideal motion states of the vehicle, the linear quadratic regulator (LQR) is used to calculate the additional required yaw moment, then, the orthogonal experimental method is applied to optimize the LQR parameters, and the target torque is allocated for the first time. Secondly, the target torque is redistributed by designing the functional relationship between the wheel sliding rate and the torque correction coefficient. Finally, the dynamics characteristics of the distributed electric vehicle with electronic differential control is simulated and analyzed in comparison with the traditional mechanical differential. The results show that the proposed electronic differential control strategy can not only achieve differential control well, but also the side slip angle and the yaw angle are reduced by up to 36.3% and 88.8% respectively, compared with the traditional vehicle. The proposed electronic differential control strategy ensures that the wheel sliding rate is always in the optimal sliding rate range, and greatly improves the vehicle lateral stability.

“…En (Khan-Ngern et al, 2018) se presenta un diferencial electrónico, con un controlador en lazo abierto, que depende sólo de la posición del volante del vehículo, medido con un potenciómetro, debido a que el controlador no tiene realimentación su implementación es fácil, pero carece de las ventajas de un controlador en lazo cerrado. En (Al-Fiky et al, 2019), se presenta un controlador para un diferencial electrónico, basado en un PID, que utiliza la medición del ángulo del volante del vehículo, aunque el controlador logra estabilizar el sistema en lazo cerrado está basado en una técnica lineal, ajustando los parámetros del controlador en un solo punto de operación, por lo que no se podría garantizar estabilidad en la región de operación no lineal del sistema. Se han utilizado técnicas de control inteligente, por ejemplo, en (Setiawan et al, 2019), se presenta un controlador para un diferencial electrónico, basado en lógica difusa; aunque este tipo de controladores pueden considerar una región de operación no lineal, pueden requerir un alto costo computacional.…”

En este artículo se presenta un esquema de control para regular la velocidad en un vehículo eléctrico con dos motores en su eje trasero. Para el giro del vehículo se requiere velocidad diferencial en los dos motores. Se presenta el modelo matemático detallado del vehículo eléctrico, contemplando las dinámicas de los diferentes componentes que lo integran y las interconexiones de todos los elementos. Se incluye un controlador basado en cinemática inversa, para calcular las referencias requeridas en cada uno de los motores. Con base en las referencias calculadas, se desarrolló un controlador robusto por modos deslizantes, para garantizar la estabilidad del sistema completo. Se realizaron diversas simulaciones para verificar el desempeño del sistema en lazo cerrado, con el esquema de control propuesto. Los resultados muestran un buen desempeño del controlador, cuando se somete a diferentes perturbaciones, tales como variaciones paramétricas y perturbaciones externas, en este caso variaciones en la masa del conductor y pendientes del camino. Además, se incluye la discretización del controlador y una propuesta para su implementación en un sistema embebido.
