A kind of subsection following steering control strategy and steering wheel input-based electronic control system were proposed to improve the steering maneuverability and security of the hydrostatic-mechanical driving crawler chassis. According to the steering analysis results of the crawler chassis under skid condition, the theoretical steering track was obtained, and it was segmented by mechanical drive axle responding time. Actual steering track followed theoretical steering track by controlling barking-clutch performance in every subsection period according to vehicle direction angle and position tolerances defined in control strategy. The evaluation system of the strategy was established, and the steering relative errors, relative steering radius ratio, executing frequency were selected as evaluation indexes. Algorithm stimulation and real vehicle test with steering electronic controller by adopting this strategy were also carried out. The stimulation results obtained by Matlab showed that the relative error of steering radius was between 5.9% and 10%, and the average frequency of actuator working was from 2.5Hz to 6.6Hz. The real vehicle test results showed that the electronic steering control system and control strategy had well steering performance, and it could meet various steering needs with stable process, and eliminate the destruction to soil and crops via decreasing the pivot steering slipping.
