A method and a system for regulating, while the vehicle is in motion, the linear position of a fifth wheel of a vehicle combination which comprises a tractor unit and a semi-trailer, which linear position of the fifth wheel is regulated automatically on the basis of the vehicle speed. Forward movement of the fifth wheel ordered in response to an increase in the vehicle speed, in order to reduce the distance between the driving cab and the semi-trailer, is effected at a faster rate of movement of the fifth wheel at times when the tractor unit is performing a gear change operation than at times when the tractor unit is not performing a gear change operation. When a rearward movement of the fifth wheel to increase the distance between the driving cab and the semi-trailer has to be effected in response to a decrease in the vehicle speed, braking of the semi-trailer relative to the tractor unit is ordered, in order thereby to facilitate the rearward movement of the fifth wheel.

A heat exchanger comprising two tanks, and a plurality of tubes for a medium which is to be cooled/heated are arranged in stacked, transverse rows, with the tubes arrayed to extend from the entrance to the exit side of the heat exchanger. The tubes are disposed between and transmit the medium between the tanks. Ducts between the stacked rows of the tubes for flow of a different cooling/heating medium. The ducts are arranged to run transversely to the longitudinal direction of the tubes. The opposing connection surfaces of the tanks converge in the direction of flow of the cooling/heating medium through the heat exchanger. The ducts closer to the connection surfaces are angled convergingly like the connection surfaces. Such a heat exchanger may be used, e.g. as a cooler, and in a motor vehicle.
