The invention discloses a speed sensorless electric crawler chassis steer-by-wire control method. A control part is composed of a main controller, an electronic differential mechanism, a left speed sensorless motor controller, a right speed sensorless motor controller, a left voltage sensor and a right voltage sensor. The main controller is connected with the electronic differential mechanism, theelectronic differential mechanism is connected with the left speed sensorless motor controller and the right speed sensorless motor controller, the left speed sensorless motor controller and the right speed sensorless motor controller are connected with a left driving motor and a right driving motor respectively, and the speeds of the left driving motor and the right driving motor of an electriccrawler chassis are controlled respectively. The left driving motor and the right driving motor are connected with the left voltage sensor and the right voltage sensor respectively, the left voltage sensor and the right voltage sensor feed signals back to the electronic differential mechanism, and the electronic differential mechanism outputs the rotating speed needed by steering to the left speedsensorless motor controller and the right speed sensorless motor controller respectively. And meanwhile, the left driving motor and the right driving motor are driven to work differentially, and steering control over the crawler chassis is achieved. The control method is used for the electric crawler chassis driven by double motors, and steering control over the speed sensorless electric crawlerchassis can be achieved.
