A METHOD FOR IDENTIFYING A ROAD CONDITION DURING DRIVING OF A VEHICLE

摘要

A method for identifying a road condition during driving of a vehicle. The vehicle includes an engine (1) with an engine output shaft connected to an automated mechanical transmission (9) via a clutch (3) . A transmission output shaft is connected to at least one driven wheel of the vehicle, and the system further includes a vehicle suspension system (55) with sensors (58) for measuring the vertical movement of wheels of the vehicle relative vehicle bodywork (57) , at least one control unit (45) adapted to receive a variety of input signals and process those signals in accordance with programmed logic rules to issue command output signals to the engine, for torque request, to the transmission for gear shifting and to the clutch. The control unit, when sensing driving conditions, sends signals indicative of a first road condition and is programmed to change gear shifting strategy for the transmission to a gear shifting strategy optimized for the first road condition if present gear shifting strategy is a second gear shifting strategy for a second road condition. One of the road conditions can be off-road.
