The invention discloses a hydraulic drive vehicle control method and device and a hydraulic drive vehicle. The control method comprises the steps that vehicle speed adjustment is conducted on a bilateral drive subsystem based on at least one preset gear; driving correlation parameters of the double-side driving subsystems in the vehicle speed adjusting process are obtained; the driving correlation parameters comprise a first driving correlation parameter of the hydraulic motor and a second driving correlation parameter of the hydraulic pump; an accelerator correction parameter or a current correction parameter is determined according to the first driving correlation parameters on the two sides, and closed-loop control is conducted on the hydraulic motor according to the accelerator correction parameter or the current correction parameter; or the pump displacement correction parameter is determined according to the second driving correlation parameter of the first side, and closed-loop control is conducted on the hydraulic pump on the second side according to the pump displacement correction parameter. According to the invention, hardware defects of the bilateral driving hydraulic system are made up based on the driving correlation parameters of the bilateral driving subsystem, and the bilateral driving linear driving control effect is improved.
