Research of high-accurate vehicle automatic levelling device based on CAN bus

In the modern vehicle weapon system, some weapons need a high-accurate levelling device to actualize precision attack. In this paper, the research of the vehicle automatic levelling device based on CAN bus was developed. Firstly, the composing of the levelling device was presented, in order to heighten the levelling accurate, a new intelligent levelling control strategy was proposed. Secondly, the design of the CAN bus communication system based on CANOpen protocol was provided, which improved the openness and standardization of the device. Finally, experimental results show that the levelling time is within 2 minute and levelling accurate is within 1, when the angle of the device is less than 15°.
