Abstract: A method is provided for resuming the movement of a motor vehicle after unforeseen stopping in an automated parking process performed by a parking assistance system having automated longitudinal and transverse guidance. If the vehicle is stopped, a decision is made about a resumption of movement of the vehicle in the prior direction of travel that existed before the vehicle was stopped. The decision is made in dependence on the remaining travel path from the current position to the next planned stopping point of the trajectory lying in the prior direction of travel. A stopping point of the trajectory can be a reversal point or the final parking position, for example. If the decision is positive, the movement of the vehicle is resumed in the prior direction of travel. If the decision is negative, the movement of the vehicle is resumed against the prior direction of travel. Alternatively, in the case of a negative decision, the movement of the vehicle may not be resumed and the parking process may be ended.

Abstract: A method and an apparatus for controlling at least one throttle cross section in a control line, in particular in a line carrying operating medium for an internal combustion engine, such as an air bypass around the throttle valve of the engine. The apparatus includes an electric control motor, by means of which a throttle device having a circular-segmental control section can be rotated. The control section is rotatable in a control opening intersecting the control line, and the control line and control opening are connected with one another by a throttle opening which has limiting faces. When the control motor is not excited or if the control motor should fail, the control section is rotated by a spring element against a stop, into a position in which a control edge together with the limiting face opens a first throttle cross section, which is sufficiently large to supply the engine with a sufficient quantity of air for the prevailing situation.

Abstract: A fuel supply unit including a pump rotor and electromotor in which the elements forming the pump rotor are constructed from a non-friction creating or low wearing material.

Abstract: An apparatus is proposed which serves to regulate the idling rpm of an internal combustion engine. To this end, a bypass valve is provided, which is disposed in a bypass around a throttle valve in the intake tube of the engine. A movable wall of the bypass valve separates a control chamber from a bypass chamber. The intake tube pressure downstream of the throttle valve in the bypass chamber prevails. The control chamber communicates via a control throttle restriction with atmospheric pressure and also, via an electromagnetically actuatable control valve which operates in accordance with operating characteristics of the engine, as well as with the intake tube pressure downstream of the throttle valve. The regulation of the idling rpm is thus effected by means of a proportional component effected by the bypass valve and an integral component effected by the pressure distribution between the control throttle restriction and the control valve.

Abstract: An adjustment device having a servomotor and arranged for rotary angle adjustment is proposed. The rotary portion is connected via a shaft with a throttle device which controls the cross section of a bypass line bypassing a throttle valve disposed in the intake tube of an internal combustion engine. The adjustment device is axially limited on one end by a cap, which is embodied as a cast part together with a portion of the bypass line. The throttle device is embodied as a rotary slide and with a control portion transversely penetrates the cap and the bypass with the control portion arranged to open the bypass to a greater or lesser extent depending on the position of the rotary slide. Between an armature of the servomotor and the rotary slide, a sealing disc is loosely guided on the shaft. As a result of a pressure drop at the sealing disc, the sealing disc can be pressed against a sealing face of the cap in order to keep the leakage air quantity as small as possible.

Abstract: A noise damping device is proposed for reducing and smoothing pressure fluctuations in a damping medium, especially in fuel supplied by fuel supply pumps, which serves to reduce pressure fluctuations downstream of the fuel supply pump. The noise damping device includes a diaphragm fluctuation damper which is disposed directly downstream of the pump compression collar and by means of which, by rotating the diaphragm fluctuation damper, an annular fitting is fixable in its axial position between the diaphragm fluctuation damper and the pump compression collar. A check valve in the connection extension of the diaphragm fluctuation damper or in the annular fitting prevents the return flow of fuel out of the fuel circulatory system after the termination of fuel supply.

Abstract: A method and an apparatus for operating a fuel supply system, in particular a fuel injection system, in which a fuel supply pump continuously supplies fuel and wherein the excess fuel not required for injection is returned to the fuel reservoir. In order to reduce the average operating power of the pump and thus reduce the average amount of fuel returned to the tank, thereby reducing undesirable temperature increases of the fuel in the reservoir, the system fuel pressure is monitored and maintained at a value substantially equal to a reference value. The electrical power of the fuel supply pump is altered continuously so as to maintain the fuel system pressure at the reference level.

Abstract: A method and apparatus are proposed for the simultaneous damping of noise on the intake and pressure sides of fluid pumps, particularly fuel supply pumps. The method comprises the diverting of peaks of variation in the supply medium from the intake and pressure sides and then bringing them together, in a common region, into operative contact under the control of a diaphragm. The peaks of variation are furthermore adjusted in such a manner, by means of the length of the connection lines surrounding them, for example, that a phase displacement of 180.degree. is produced in the variations for the purpose of mutual compensation of the pressure variations on both sides which cause the generation of noise.

Abstract: This invention relates to a pump and motor unit which is particularly adapted for supplying fuel and which comprises a pump rotor and motor armature, the bearings of which are disposed independently of each other on a fixed axis.
