The invention discloses a walking device for a crawler chassis, a control method and a crawler chassis system. A walking device for a track chassis comprises a linear walking controller, and the linear walking controller is configured to receive an input longitudinal speed instruction; acquiring the rotating speeds of the first and second driving wheels and the transverse deflection angle of the crawler chassis in real time; determining a reference drive signal based on the longitudinal speed command and the first drive wheel speed; generating a drive signal first correction value based on the lateral deflection angle; determining the total transverse dislocation amount of the crawler chassis based on the transverse deflection angle and the rotating speed of the second driving wheel; generating a driving signal second correction value based on the total transverse dislocation amount; taking the larger absolute value in the first correction value of the driving signal and the second correction value of the driving signal as a correction value of the driving signal; generating first and second driving signals based on the reference driving signal and the driving signal correction value; and controlling the opening degree of the first and second electric proportional valves based on the first and second driving signals.
