  • Patent number: 6664662
    Abstract: Method and device for controlling an auxiliary unit (10) in a motor vehicle by means of a device consisting of a control unit (40) and a switch (30) for switching the auxiliary unit on and off. To ensure the maintenance of an auxiliary unit of this type and to prolong its life using simple means, it is proposed, among other things, that the control unit (40) will repeatedly signal actions to be taken to a driver of the vehicle or directly to the switch. A first action is the switch-on of the switched-off auxiliary unit (10) at a specific point in time if it (the unit) has been switched off for a long period of at least some weeks. A second, succeeding action is the switch-off of the unit (10) switched on in the manner described, after a short period of at least some minutes.

  • Patent number: 6598895
    Abstract: A towing vehicle includes a body on two frame side members and a towing device supported on the members. The frame side members extend substantially parallel in the longitudinal direction of the vehicle and are in a plane parallel to the surface on which the vehicle travels. The towing device is mounted on a towing beam which extends between the two frame side members at the rear of the vehicle and the towing device is couplable to a towable vehicle. A support arrangement at the rear of the vehicle is connected to the two frame side members and incorporates at least one and preferably two beams which are connected respectively to one of the frame side members either directly or by a connecting element that extends laterally outwardly from the respective frame side member. The beams are connected to a support member that extends across the body. The beams extend at an angle of inclination relative to the plane.

  • Patent number: 6558292
    Abstract: In a vehicle's driveline, the clutch between drive engine and gearbox has the task of ensuring a final speed adjustment between the engine and the gearbox at the time when the clutch pedal is allowed to rise on completion of a gear change. The invention has the object of reducing the stress on the clutch and the disadvantages which arise from a lengthy sliding-in process with large speed differences. This is achieved by adjusting the engine speed to the gear being engaged, so that only a small speed difference has to be absorbed in the clutch.

  • Patent number: 6375248
    Abstract: A side curtain for the superstructure of a freight vehicle has its upper edge arranged for longitudinal movement at an upper portion of the superstructure. The bottom edge of the curtain includes a relatively rigid engaging device which extends along substantially the whole length of the curtain, is releasably connectable to a tensioning device. The engaging device has evenly spaced bending notches which, when the engaging device is at least partially freed from the tensioning device, guides the folding of the curtain during movement of its upper edge towards a non-covering position.

  • Patent number: 6330877
    Abstract: An arrangement and a method for calibration or monitoring a combustion process in a combustion engine, wherein an injection device injects fuel into a combustion chamber of the combustion engine. A noise-detecting sensor at the engine detects a parameter which derives from the noise generated during the combustion process. A control unit receives signal values representing the parameter from the sensors and receives information on the rotation position of a crankshaft in the combustion engine. The control unit determines the crankshaft position when the fuel is injected into the combustion chamber. Thereafter the injection device can be calibrated. Detecting the noise from combustion also makes it possible to assess whether combustion takes place at the intended time.

  • Patent number: 6318802
    Abstract: In an arrangement for a seat (2) in a vehicle, the seat is movable in a longitudinal direction along a plane (33) which slopes relative to the horizontal plane. The subframe of the seat (2) consists of devices (30, 31) fastened respectively to the vehicle and to the seat, which devices consist of two substantially similar triangular supporting frames. Resetting between a predetermined driving position and a likewise predetermined resting position is made possible by a control device (16) which is fastened to the device (30) which is itself fastened to the vehicle, which control device cooperates with a locking device fastened to the seat so that during a relocating movement between forward and rear positions of the seat the locking device (17) becomes free from at least one locking position between the vehicle seat and the device (30) fastened to the vehicle.

  • Patent number: 6277022
    Abstract: An arrangement for ventilation of a space in a vehicle incorporating at least one first outlet device (6) for discharge of air from the space and at least a second outlet device (7) for discharge of air from the space. The first outlet device (6) is arranged at a higher position than the second outlet device (7). Means (10, 11) are designed to allow discharge of air from the space in such a way that a main portion of the air discharged flows through the first outlet device (6) when the temperature of an environment is relatively high and that the main portion of the air discharged flows through the second outlet device (7) when the temperature of the environment is relatively low.

  • Patent number: 6253751
    Abstract: Fuel proportioning in a gas-powered combustion engine is effected so that when the value of a parameter monitored in the exhaust gases deviates from a set-value, the level of the gas input pressure to a mixer for gas and air is adjusted in a specified operating situation so that said set-value is established. A device for fuel proportioning includes a pressure regulator (3) whereby the outlet pressure can be adjusted automatically during a specified operating situation by means of a control unit (11). After adjustment has been carried out, the setting reached is maintained for a lengthy period.
