Abstract

The invention relates to a method for determination of a state of a gearbox of a driveline of a motor vehicle at the putting into engagement of a clutch of said driveline. The method is characterised by the steps of: - establishing a first angular velocity representing the angular velocity of the gearbox input shaft; - establishing a second angular velocity representing the angular velocity of the gearbox output shaft; - determining said state of the gearbox on the basis of said first and second angular velocities; and / or the steps of: - establishing the vehicle's engine torque; - establishing an angular acceleration of the gearbox input shaft; - determining said state of the gearbox on the basis of said torque and angular acceleration. The invention relates also to a device, computer programme and computer programme product with programmes codes for improving the performance of a motor vehicle. The invention relates also to a motor vehicle which has such a device installed.

Description

Technical field [0001] The invention relates to a method for improving the performance of a motor vehicle. The invention also relates to a computer program product comprising program code for causing a computer to execute the method according to the invention. The invention also relates to a computer and a motor vehicle equipped with the computer. Background technique [0002] Motor vehicles may be equipped with automatic clutches. In such vehicles, there are sensors that indicate whether the gearbox of the vehicle is in a neutral position or whether the gears are engaged. However, such a sensor may incorrectly indicate that the gearbox of the vehicle is in the neutral position. If the sensor incorrectly indicates that the gearbox of the vehicle is in the neutral position and the clutch of the vehicle is slipping, it will cause undesirable consequences, such as the vehicle starting to move, posing a safety risk. One way to deal with this problem is to provide more and more pr...
