With the development of new energy technology, pure electric pickup trucks have shown great potential in the off-road field due to their unique power characteristics. However, the complex and changeable road adhesion conditions restrict the precise control of their longitudinal force. This paper systematically reviews the key technologies of longitudinal force control for off-road pure electric pickup trucks. By analyzing the configuration of the power system, a hierarchical collaborative control architecture and integrated actuator are proposed. Focusing on intelligent algorithms such as fuzzy logic control, sliding mode variable structure control, and model predictive control, this paper expounds their advantages in dealing with system nonlinearity and achieving multi-objective optimization. Simulation and real vehicle verification show that the intelligent algorithm can significantly improve the longitudinal force control accuracy and system robustness in scenarios such as starting on low-adhesion roads compared with traditional methods, providing a reference for the development of high-performance pure electric off-road control technology.
