Acceleration control of lorry internal combustion engine

摘要

The method involves deriving a signal representing the actual rate of sliding (Sx) of the motorised wheels of the vehicle. This is compared with a reference rate signal (Sxc), forming a resultant between these rates. This resultant signal represents the rate of reduction of torque delivered by the engine to the wheels. This is controlled to produce an actual slip equal to the reference rate.The signals are sampled and treated in digital filter circuits, established by a dynamic model of the wheel train accelerated by the engine torque. A computer (7) and controller (6) of the engine torque are supplied with signals from wheel speed sensors (1-4). The controller may adjust the engine fuel injection time, air/fuel mixture ignition advance or fuel valve.
