A method and an arrangement for indication of clutch slip in a manually controlled friction clutch (21) in a vehicle with manually controlled mechanical gearbox (23), including a device for calculating a value representing the energy released in the clutch (21) on the basis of an expression for the torque of the engine (20) and clutch slip, and devices (9, 12) for generating an attention-drawing signal when the calculated energy released exceeds a certain predetermined level. The invention is distinguished by: a device (5) for at least substantially continuously calculating the relationship between the engine's speed (3, 4) and the vehicle's speed (1, 2); a device for recording the change over time (5, 6, 8) in the value of this relationship; and devices (9, 12) for indicating the occurrence and non-occurrence of clutch slip and its magnitude during utilisation of said recorded change. |
