Method for controlling automatic reduction of motion and control system for controlling automatic reduction gear

摘要

Method for detecting false neutral and system for controlling the reduction gear in a system of automated transmission. A method and system for controlling the reduction of motion in an automated mechanical transmission system (10) used in a vehicle.When an automatic reduction of reverse power from a gear currently engaged (GR) is required, the acceleration of the engine (AE) is monitored and compared with a free acceleration of the engine (FEA) to detect a false condition of neutral and to adopt action Propriada according.Alternatively, a false condition of neutral is detected when the absolute value of the rotational speed of the output shaft (the) times the currently engaged gear (GR) less than the rotational speed of the input shaft (s) is smaller than a predetermined value (ABS * GR) - is).
