无人履带平台发动机控制技术

With the rapid development of robotics and intelligent technology, unmanned equipment has gradually become a trend in many countries. Unmanned equipment is an important part of the military reservesfor itsoutstandingterrain trafficability and environmental adaptability. Its driving environment is complex, and the requirements for diesel engine speed regulation characteristics vary under different working conditions. Based on the mechanical speed control engine of anarmored personnel carrier, the electronic control unit (ECU) hardware and software systems are designed, and the diesel engine is modifiedelectronically. The ECU control system is capable of intelligent automatic start and turn-off, switchingof operating status, self-diagnosis, and fault processing. At the same time, it can switch speed regulation characteristics to adapt to the different working conditions of the unmanned equipment. When driving straight on a flat road, the engine uses the same throttle characteristics as the mechanical speed control engine to adapt to the gearbox shift curve. In the steering mode, the speed regulation is changed to improve the accuracy of vehicle path tracking. The improved electronic speed regulation diesel engine is installed on abench for testing and verificationof its speed regulation characteristics. The results can meet the needs of unmanned tracked platforms.
