Abstract: The invention relates to method for operating a drive system for a motor vehicle comprising an internal combustion engine (1) and an electric machine (6), it being possible to accelerate a driveshaft (4) of the internal combustion engine by means of the electric machine (6), and in the event of an upshift and/or when an upshift is initiated, an idling rotational speed of the driveshaft (4) is increased by the electric machine (6). If a turbocharger is used to increase the charge pressure, an increase in the idling rotational speed by the electric machine can compensate for low efficiency of the turbocharger at low rotational speeds.

Abstract: In a wheel support structure of a commercial vehicle including an axle with a jaw structure having two bearing bores and a stub protruding into the jaw structure with a pin extending into the stub and into the bearing bores, the bearing bores are closed adjustably by screw caps threaded into the bearing bores for adjusting the pin position and setting a predetermined moment of friction between the bearing elements.

Abstract: The invention relates to an internal combustion engine which has charge-air supercharging by means of an exhaust-gas turbocharger and secondary air injection, the flow path of which is selected in such a way that the quantity of secondary air injected has an influence on the rotational speed of the turbocharger. By monitoring the rotational speed of the turbocharger, an increase in the rotational speed caused by the secondary air injection is determined, and the quantity of secondary air injected is worked out from the increase in rotational speed. This has the advantage that there is no need for complex temperature-measuring methods as have hitherto been employed. Rotational speed measurement can be carried out contactlessly and with absolutely no wear in particular by means of inductive rotational-speed sensors. Moreover, these inductive rotational-speed sensors can be miniaturized and produced at extremely low cost.

Abstract: The invention relates to a device for protecting a battery from electrostatic charging. In particular, the invention is directed to an electrically conductive covering for a vehicle battery having a plastic casing. The type of plastics typically used in casings for vehicle batteries have a tendency to develop electrostatic charges. The accumulation of such charges can result in flash overs that can damage the battery and, in certain circumstances, can result in explosions. The covering may be a film having a surface resistance of <1·109 ohms that is connected to one of the terminals of the battery, thus draining the electrostatic charges that might otherwise build up. The covering may be provided with various features, including ribbing that preserves the structural integrity of the covering as well as different structures to hold down the covering on the battery. The covering is designed so that it can be customized to fit various battery types and sizes and is also reusable.

Abstract: A method for producing an elongate hollow member that includes a laterally protruding mounting component, the mounting component is formed from the hollow member. For this purpose the latter, at a point about a horizontal axis intersecting the central longitudinal axis of the hollow component at an angle of approximately 45°, is bent upwards or downwards at an angle of approximately 90°, such that the bent section projects transversely in relation to the longitudinal extent of the remainder of the component. The lateral projection of the bent section is then angled at an offset height in relation to the remainder of the component to form the mounting component.

Abstract: A vehicle-useful, high-resolution 3D-detection of the environment of a street vehicle with environment scanning sensors is not possible today. Depending on application the first commercially available vehicle integrated systems may be a comprise between resolution of the sensors and size of the sampled area. With the inventive two dimensional distance resolution sensor device it becomes possible, in contrast to those which are known, to produce a system which, installed in a street vehicle, detects and preferably processes complex dynamics scenarios such for example street traffic, from the prospective of the active dynamic moving vehicle. Therein a three dimensional image of the environment is produced using a distance sensor, which produces a two dimensional distance profile (depth profile), and on the other hand, using a data processing and a storage unit, which process and store sequential distance profiles and sequence a series of distance profiles into the three dimensional image of the environment.
