Abstract: The invention relates to a motor vehicle diagnostic system for acquiring and storing diagnostic data and transmitting them from control units in a motor vehicle to a computer outside the motor vehicle. The system is composed of components which are located inside the vehicle and of components which are located outside the vehicle. Using a transmission module, in which a short diagnostic test is implemented, diagnostic data from onboard components are interrogated and are transmitted via a WLAN link to the computer system of a service company. The diagnostic data of the onboard components can be further processed using the computer system. The disclosed invention is aimed in particular at assisting a service employee in the vehicle reception of a service workshop.

Abstract: A motor vehicle rear end is delimited by a rear bulkhead, side wall regions, and a rear cover. An air separation edge extends on the rear cover in the width direction of the motor vehicle. Lateral rear lights are integrated into the motor vehicle rear end, and include means, which are arranged in the side wall regions, for release of the side wall flow, and which extend at a distance below the air separation edge over a height region of the associated rear light (20) and at a distance from the rear bulkhead. At least one opening, through which air flows, is provided in a covering element arranged at the end of an air duct as a means for release of the side wall flow in both side wall regions.

Abstract: The invention relates to restraint system for a passenger of a vehicle who sits on a vehicle seat that can be placed in different positions. Said restraint system comprises an interior that is defined by a housing (1) and at least on gas bag, and at least one triggerable outlet (36-38) which is disposed on the housing (1) and can be closed by means of a closing element (3) that is movable from a closed position into an open position such that an internal pressure in the interior can be adjusted in accordance with passenger load-relevant parameters during an accident.

Abstract: In a method and device for adjusting an electro-dynamic brake of an electric camshaft adjuster for a phase angle adjustment of a camshaft of an internal combustion engine with respect to the crankshaft thereof, the phase angle is controlled by means of a position controller and the adjustment speed of the phase angle of the camshaft with respect to the crankshaft is controlled by means of an adjustment speed controller by controlling the current through the electro-dynamic brake by means of a further adjustment device and the use of Pilot controls to improve the control behavior of the cascade controller.

Abstract: In a device for a motor vehicle for providing data relating to an accident, the data relating to an accident includes both position data of the motor vehicle and data relating to the vehicle, which in turn includes recovery-related specification data. Furthermore, a conversion device is for converting an emergency call which is received by such a device, the recovery-related specification data being converted automatically into a reproduction form which is understandable for persons involved in the recovery, and output.

Abstract: A method and apparatus for detecting the presence of a prescribed heat exchanger, such as a catalytically active radiator, in a motor vehicle are performed during operation of the motor vehicle. The temperature of a heat-exchanger medium is observed together with further current operationally relevant parameters of the motor vehicle for a prespecified time window. An expected temperature gradient over time of the heat-exchanger medium is detected, as well as the current temperature gradient over time of the temperature of the heat-exchanger medium. The presence of a prescribed heat exchanger is detected taking into account the expected temperature gradient and the current temperature gradient.

Abstract: A sound system which has, for example, a radio, a cassette and a CD player is usually already installed in cars as standard or as an option. In addition, a better sound system comprises a box system which has a tweeter and a woofer. In order to provide a speaker box which is suitable particularly for dispensing frequencies below 150 Hz and at the same time has neat pulses accompanied at the same time by little distortion, pulse dynamics and is highly effective, a sound transducer (10) is introduced into the supporting structure of the vehicle. This takes place in such a manner that subcompartments which are separated from each other adjoin each of its two membrane sides. In this case, the two subcompartments of the speaker box are formed by at least two elements (2, 3, 4) of the supporting structure of the vehicle (1).

Abstract: A method for curing a chemical composition, the composition containing at least one or more binders having ethylenically unsaturated groups, as well as one or more initiators for triggering a radical polymerization. The method includes a thermal curing step, in which the curing of the composition is effected by a radical polymerization of the binder, which is triggered by a thermal initiator and is carried out under protective gas. Paint films having improved mechanical properties can be produced using the method according to the present invention.

Abstract: In a supercharged internal combustion engine having an intake duct and an exhaust gas recirculation system and comprising an exhaust gas turbine with two separate flow passages of different flow cross-sections arranged upstream of a turbine rotor of the exhaust gas turbine, each flow passage being in communication with a respective engine exhaust line for supplying it with exhaust gas and an exhaust gas recirculation line extending from one of the engine exhaust lines to the engine intake duct, a bypass line bypassing the exhaust gas turbine is provided and a common control element is arranged in the recirculation line of the exhaust gas recirculation system and in the bypass line for controlling the exhaust gas flow from the recirculation line selectively to none or any of the intake duct and the turbine bypass line.

Abstract: The invention relates to a steel piston for internal combustion engines, comprising at least one piston upper part (12) provided with a combustion cavity (11) and an annular wall (5), and a piston lower part (13) provided with a connecting rod bearing (8). The steel piston is cast as a single component from a reduced-density steel alloy or a special steel alloy in the same material by means of a low-pressure casting method.

Abstract: A displacement control mechanism for a variable displacement compressor includes a first valve hole, a first valve body, a pressure sensing means operable to sense pressures of first and second points in a discharge pressure region to adjust a position of the first valve body, and a pressure-difference-increasing means operable to increase pressure difference between the first and second points when the pressure of a suction pressure region falls below a predetermined standard pressure. The pressure sensing means displaces the first valve body to increase an opening degree of the first valve hole according to increase of the pressure difference when the first valve hole is part of a supply passage. The pressure sensing means displaces the first valve body to decrease the opening degree of the first valve hole according to the increase of the pressure difference when the first valve hole is part of a bleed passage.
