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.
