  • Patent number: 6446600
    Abstract: A sensor arrangement and engine management device for a combustion engine, the engine management device including the sensor arrangement for detecting variables indicative of engine load, a mechanism for determining engine load on the basis of measured values supplied by the sensor, as well as a throttle-valve position control loop. At least two of the sensors of the sensor arrangement, which may include a mass air-flow sensor, an intake-air temperature sensor, an induction-pipe pressure sensor, and a throttle-valve position sensor, are microintegrated in a modular unit. The engine management device is made such that a sensor device with the at least two sensors, the mechanism for determining, engine load and/or the throttle-valve position controller used in the throttle-valve position control loop are microintegrated in a modular unit. The engine management device can be used, for example, for controlling a spark ignition engine in a motor vehicle.

  • Publication number: 20020092300
    Abstract: An engine brake for a supercharged internal combustion engine for driving a motor vehicle is operated such that the working gas compressed during engine braking, prior to the end of the expansion cycle, is drawn at least partially from the working chambers of the engine through at least one throttle valve, with an exhaust turbocharger of the engine having an exhaust turbine with variable turbine geometry. The engine braking power is regulated based upon the travel of the throttle valve and/or an intake cross section of the exhaust turbine as a function of the operating parameters of the internal combustion engine and the vehicle driving speed. Upon issuance of a signal indicating a braking performance requirement from the driver, the required braking power is applied at least preferably through the engine brake.

  • Publication number: 20020014007
    Abstract: A method for manufacturing an air-gap-insulated exhaust pipe having a branch stub, as well as an exhaust pipe produced according to such a method and a tool for forming such an exhaust pipe. Two tubes are inserted into one another to form a double tube. The double tube is placed in a first internal high-pressure shaping tool, and exposed to internal high pressure fluid such that it expands to match the contours of the engraving of the first shaping tool, and a double-walled branch stub is blown out of the double tube. The partially formed double tube is then placed in a second internal high-pressure shaping tool, with the double tube being surrounded, between the two ends including the branch stub, circumferentially and throughout by a corresponding design of the engraving, by an expansion chamber.

  • Patent number: 6343417
    Abstract: A process for manufacturing an air-gap-insulated exhaust elbow of a motor vehicle exhaust system achieves in a simple manner a manufacturing of space-saving air-gap-insulating exhaust elbows which is reliable with respect to the process and can be precisely reproduced. The exhaust elbow is joined together from several air-gap-insulated exhaust pipes as well as the pertaining entry flanges and the exit flange, which, by way of an internal high-pressure metal forming process, are shaped in an air-gap-insulating manner from one double pipe respectively. The ends of the air-gap-insulated exhaust pipes which are to be connected with one another are first trimmed while opening the respective air insulating gap and are then fitted into one another. In such case, the ends are shaped such that the fitted connections of the outer pipes and of the inner pipes of the exhaust pipes to be connected are made with play.

  • Publication number: 20020011366
    Abstract: A method for determining an initiation threshold value for an automatic braking process, in which an automatic braking process is used and a brake pressure is produced which is greater than the brake pressure which corresponds to the operation of the brake pedal by the driver. Short distances between vehicles increase the risk of accidents. If a driver operates the brakes when there is a short distance between the vehicle and the preceding vehicle, in the vast majority of cases, the driver of the following vehicle is often required to perform an emergency braking due to the short distance between the vehicles. To improve the safety of vehicles, an emergency braking is performed, as quickly as possible, when the distance between vehicles is short. This emergency braking, within what is physically possible, ensures rapid deceleration of the vehicle and thus helps to avoid rear-impact accidents.

  • Patent number: 6295000
    Abstract: A method for assessing actuations of the accelerator by a vehicle driver to detect the nervousness of the driver, the cumulative path covered by the accelerator, in terms of amount, being evaluated within a predefined time window when the change in velocity is less than a predetermined threshold value and/or the change in position of the accelerator is less than a predetermined threshold value within this time window. Furthermore, alternatively and/or additionally, the number of reversals of the algebraic sign of the time derivation of the accelerator position can be taken into account.

  • Patent number: 6273222
    Abstract: A brake unit including a brake disc of a material having a high thermal loading capacity and a brake pad that cooperates with it in tribological fashion. The brake disc is essentially made of a short-fiber reinforced ceramic material, whose thermal conductivity, in particular transversely to the disc surface, is at least 20 W/mK, preferably about 30 to 45 W/mK. The brake disc is combined with a brake pad having an organically bonded matrix. The brake pad may be a conventional series brake pad. The brake unit provides an optimal pairing of a brake disc, having a high thermal loading capacity, with a conventional brake pad in light of a reasonably expected brake pad service life, and in light of other tribological requirements, such as the friction coefficient.

  • Patent number: 6216068
    Abstract: A method for driver-behavior-adaptive control of a variably adjustable motor vehicle accessory. One or more parameters indicative of driver behavior are sensed and a pertinent driver behavior is ascertained therefrom. Accessory adjustment is performed variably as a function of the driver behavior that was ascertained. The driver behavior is ascertained in terms of a long-term driving manner component, and a short-term dynamic demand component and/or a steady-speed request component. Accessory adjustment is performed, if a short-term dynamic demand exists, in accordance with an adjustment characteristic having a dynamic level corresponding at least to that dynamic demand. When a constant-speed request exists, accessory adjustment is performed in accordance with a relevant low-dynamic adjustment characteristic. Otherwise, accessory adjustment is performed in accordance with an adjustment characteristic determined by the long-term driving manner component.
