Abstract: The present invention relates to a method for operating a charging device for charging energy stores of vehicles, preferably electric vehicles or hybrid vehicles, wherein the charging device is connected to an Internet-enabled server. In a method step, at least one receiver vehicle with a flat or partially charged battery communicates its charging demand to the charging device. Furthermore, in a method step at least one donor vehicle with an at least partially charged battery communicates its readiness to charge to the charging device.

Abstract: A method for testing an integrated circuit and an integrated circuit. The integrated circuit has an internal testing structure which may be accessed via an internal test access port and a control bus which is conducted to the outside via control ports, it being possible to switch over between a running mode and a test mode so that, in the test mode, the test access port is accessed via the control ports and the control bus, thus testing the integrated circuit.

Abstract: A pressure pump device for a hybrid vehicle, which is drivable by a combustion engine having a fuel pressure accumulator and by an electric drive. The pressure pump device includes a pressure pump, which is mechanically connectable to the electric drive for supplying fuel to the fuel pressure accumulator.

Abstract: The invention relates to a structural theft protection system for motor vehicles with a blocking control device (30) for releasing a motor control device (31), a code acquisition device (20, 21) that is connected to the blocking control device, and a device (32) connected to the blocking control device (30) for acquiring a vehicle use parameter (T, S), as well as with several locally fixed code takeover/output stations (10, 11), wherein the blocking control device (30) keeps the motor control device (31) in the release position only if the blocking control device (30) is fed a new release information by one of the locally fixed code takeover/output stations (10, 11), preferably at regular intervals.

Abstract: A method for generating a signal (TAn) responsive to the induction air temperature of an internal combustion engine. The signal (TAn) for the induction air temperature is determined from a signal (TMot) for the temperature of the internal combustion engine, from a signal (TU) for the ambient temperature, and from a correction factor K. Correction factor K is a function of a signal (mL) and/or a vehicular speed signal (v), signal (mL) representing either the induction air quantity or the air mass of the internal combustion engine. To enable the most accurate possible simulation of induction air temperature, even under changing operating conditions, the signal (TAn) for the induction air temperature is filtered, it being possible to variably select the time constant (ZK) of the filter in response to rising and falling induction air temperatures.

Abstract: A control device has a microcomputer, a memory which has a control program and can be cleared and programmed electrically, a read-only memory and a serial interface. In the read-only memory, a program for reprogramming the memory which can be cleared and programmed electrically is stored. For the reprogramming of the memory which can be cleared and programmed electrically, the control device receives the data to be programmed from an external communication device via the serial interface. The control device causes the program for reprogramming the memory which can be cleared and programmed electrically to be processed without the control program having to be started or operative for this purpose.

Abstract: A vehicle security system with an anti-theft controller which conducts a data exchange with at least one function controller, particularly an engine controller, in order to control its operational readiness, wherein the data exchange is conducted via a data line connecting at least the anti-theft controller and the function controller. Alternatively, an external device (4) can be connected to the data line (1), with the device being configured for the exchange of data with at least one of the controllers (2, 3, 3', 3") The data line is a line which is already in existence in the vehicle, particularly a K-diagnostics line and/or an L-diagnostics line in accordance with ISO standard 9141. For the control of the data exchange, one of the controllers (2, 3) connected via the data line (1) exercises the functions of the control unit.

Abstract: The ignition system for a four-cycle gasoline engine having at least one cylinder includes a spark plug for each cylinder and an ignition coil for each spark plug so that each spark plug has its own ignition coil with a primary and secondary side as well as a control device for controlling the timing of the firing of the spark plugs via the individual ignition coils according to a predetermined firing sequence connected to each of the ignition coils.
