Aimed at the driving asynchronism caused by difference of volumetric efficiency and properties of the driving units on heavy rubber-tyre type walking machine during walking process in the high-speed railway construction,the characteristics and reasons for asynchrony of the pump control motor hydraulic system are analyzed. The deficiencies of the control strategy were summarized based on speed synergy, and a control strategy was proposed based on driving force synergy of the front and rear vehicle and the congruent relationship was given between the driving force of the front and rear vehicle. Finally, the field tests were carried out to verify the control strategy.The results show that the control strategy based on the driving force synergy can effectively improve the driving performance of the whole vehicle, and solve the asynchrony problem between the front and rear vehicle, which provides a new idea for the synchronous control of the heavy tyre type walking machinery of the multi driving system.
