Abstract: The invention relates to a drive module for a vehicle, wherein the drive module is adapted to be releasably connected to a functional module for forming an assembled vehicle, the drive module comprising: at least a pair of wheels; at least one propulsion unit connected to the pair of wheels; at least one energy storage unit for providing the propulsion unit with energy; a control device configured to operate the drive module as an independently driven unit; and at least two interfaces for releasable connection with a functional module, each interface being arranged on different sides of the drive module. The invention also relates to a vehicle assembled from a set of modules.

Abstract: The invention relates to a method performed by a first control device for controlling assembly of a vehicle from a set of modules, the set of modules comprising: at least one drive module and at least one functional module, wherein the at least one drive module comprises a pair of wheels and is configured to be autonomously operated, and wherein each module in the set of modules comprises at least one interface releasably connectable to a corresponding interface on the other module, the method comprising: commanding a second control device of the at least one drive module to physically connect the at least one drive module with the at least one functional module to assemble a vehicle; and receiving, from at least one of the modules of the assembled vehicle, a verification of the connection between the modules.

Abstract: 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.

Abstract: 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.

Abstract: A control device in a vehicle, which control device is connected to, and is for operating, a semi-automatic gearbox, can be set in various gearchange function positions and can, in at least one gearchange function position for traveling forwards, be operated for gear changing. The control device is also connected to, and is for operating, a supplementary brake. This control device replaces both the gear lever and the supplementary brake lever, resulting in increased driving safety and better ergonomics for the driver.

Abstract: The invention concerns an arrangement for regulating the speed of motor vehicles with an internal combustion engine and additional braking systems. An operating element (2) of the speed-regulating arrangement has switching positions (4, 6, 8, 20, 22, 24, 42, 44, 52, 54, 56) for influencing the engine control braking stages and switching positions (10, 12, 14, 16, 17, 26, 28, 30, 31, 32, 58, 60, 62, 64, 66) for influencing the braking system braking stages. The first and second switching positions can be in a single switching plane (18). A second switching plane (40), which is perpendicular to the first switching plane (18) and comprises speed-regulation switching positions (42, 44), can additionally be provided. Retarders, engine brakes, exhaust flap brakes or the gear control system in an automatic transmission can serve as braking devices.
