Motor vehicle e.g. private car, speed controlling system for e.g. speed limiter, has controller estimating engine torque set value from instant torque and set speed based on vehicle evolution model and signals representing instant speed

摘要

The system has a sensor (3) generating a signal representative of an instant torque of an engine. A controller (4) estimates a set value of an engine torque from an instant engine torque and a vehicle set speed based on an evolution model of a motor vehicle and signals representing an instant speed of the vehicle. A unit (5) generates a signal representing the engine torque set value estimated and transmitted towards a device (6) controlling the engine torque.
