The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. Method for determining the engaged box ratio in a gearbox, wherein the engaged gearbox ratio is determined when there is a change of gearbox ratio by dividing one by the other the values of an engine speed measured just before and just after the change of gear and by comparing the result of this division with stored predetermined values that depend on the gearbox (8) fitted to a vehicle.
2. The method for determining the engaged box ratio as claimed in claim 1, wherein said gearbox (8) is coupled to the engine (6) via a clutch (10), and wherein the change of gearbox ratio is detected by a sensor placed on this clutch (10).
3. A method for determining the speed of a vehicle with the aid of sensors on board the vehicle, the vehicle being moved by an engine (6) coupled to a gearbox (8),
wherein the speed of the vehicle is determined by multiplying the value of the engine speed (N) obtained via a sensor by a predetermined coefficient as a function of the engaged gearbox ratio, and wherein the engaged gearbox ratio is determined by applying a method as claimed in claim 2.
4. The method for determining the engaged box ratio as claimed in claim 2, wherein the sensor placed on the clutch (10) is a contactor.
5. A method for determining the speed of a vehicle with the aid of sensors on board the vehicle, the vehicle being moved by an engine (6) coupled to a gearbox (8),
wherein the speed of the vehicle is determined by multiplying the value of the engine speed (N) obtained via a sensor by a predetermined coefficient as a function of the engaged gearbox ratio, and wherein the engaged gearbox ratio is determined by applying a method as claimed in claim 4.
6. The method for determining the engaged box ratio as claimed in claim 4, wherein the value of the engine speed is stored on each change of state of the contactor.
