The invention relates to a method and arrangement for determining a current road inclination, specifically taking into account a quality measure for the determination. The invention also relates to a corresponding computer program product. The method comprises the steps of: &#x2014;measuring (S), a first vehicle operating parameter; &#x2014;receiving (S) the first vehicle operating parameter; &#x2014;determining (S) an indication of a quality level for the first vehicle operating parameter, and &#x2014;determining (S) an estimated value of the current road inclination based on the first vehicle operating parameter and the indication of the quality level for the first vehicle operating parameter.

Method and arrangement for determining road inclination

The invention relates to a drive arrangement for a vehicle and a method for gear shifting in a vehicle. The drive arrangement () comprises at least a first drive axle () operatively connected to a first gear box () and a first propulsion unit (). The drive arrangement () further comprises a second gear box () and a second propulsion unit () operatively connected to the first drive axle () or to an optional second drive axle (). The drive arrangement () further comprises at least one electronic control unit (ECU) adapted to govern gear transmission of the first and the second gear boxes (). The electronic control unit (ECU) is configured to automatically select between shifting gear on the first and the second gear boxes () simultaneously, or sequentially. The drive arrangement and the method provides for a very versatile drive arrangement and gear synchronization providing comfort for the driver and the passengers as well as improved vehicle dynamics.
