An Automatic Math Method to Identify Vehicle Gearshift Action Based on Operating Lever Displacement Recorder

Because driver´s action cannot be remembered and reappeared during tank steer training, whose skill is estimated only by teacher´s subjective judgment. In order to solve this problem, some new methods are designed, which include using operating lever displacement to record driver´s activity, using state changing matrix to reflect driver´s operation process, using activities sequence of steer rule to Identify driver´s action, thus driver´s activity can be recorded, identified and evaluated by computer.
