Patent ID: 7591759

Claim:
A propulsion control system for a motor vehicle having a propulsion system ( 1 ) which includes an internal combustion engine (E) with a shaft (S) that can be coupled to a transmission ( 2 ) including a gearbox (G); the system including: a control accelerator (A) with associated electrical detector means (S 1 ); sensor means (S 2 ) for supplying electrical signals indicating a speed of rotation (n) of the shaft (S) of the engine (E) and/or a speed (V) of the motor vehicle; and electronic control means (SCU) operable to control the propulsion system ( 1 ) of the motor vehicle in a predetermined manner in dependence on signals supplied by said detector means (S 1 ) and said sensor means (S 2 ); wherein the accelerator (A) is associated with: a sensor (S 1 ) operable to supply electrical signals indicating a force (F p ) applied to the accelerator (A) by the driver, and an actuator device ( 6 ) operable to modify the position of said accelerator (A), and in that the system control means (SCU) are operable to: acquire the signals emitted by said sensor (S 1 ) and establish an instantaneous traction force (F x ), which drive wheels (W) will develop on the ground, corresponding to the instantaneous value of the force (F p ) applied to the accelerator (A) by a driver; and control said actuator device ( 6 ) in such a way that it tends to place the accelerator (A) in a position corresponding, according to a predetermined function, to the instantaneous value of the speed (V) of the motor vehicle.
