<p>An automated mechanical gearbox system characterised in that it includes control means (420) for controlling an automatic or semi-automatic gear change operation mode of the gearbox (100). The driver-operated gear lever (320) transmits the driver request to a computer module (400) via sensors (340). The module (400) performs the requested gear change after analysing the validity of the driver request by then controlling the clutch, selection and engagement control solenoid valves (216) and interacting with an engine control computer (500) to provide suitable engine speed and torque control during the gear change. The commands are confirmed by position sensors (206) on the actuators (200, 202 and 204) and the engine speed sensors (102, 120), at the input and output of the gearbox. The absolute gear ratio engaged in the gearbox (100) is shown on a display (410).</p> |
