摘要:
A vehicle diagnosis system for ascertaining, storing and transmitting diagnosis data from control units in a motor vehicle to a computer outside of the motor vehicle has components which are inside of the vehicle and components which are outside of the vehicle. The onboard components are capable of autonomously requesting diagnosis data from control units, buffer-storing the diagnosis data and of transmitting the diagnosis data to offboard components. The offboard components can be used to configure the onboard components, to visually display the transmitted data and to forward said data to subsequent systems. Access is effected using a communication module, which is preferably implemented in a diagnosis control unit with a dedicated gateway and which is not the control unit for the central locking. A gateway for diagnosis applications is present in the vehicle in the case of vehicles with a diagnosis CAN bus or with another diagnosis bus.

The invention relates to a computer-based diagnostic tester which can exchange information with the control devices installed in the motor vehicle using a diagnostic program via a diagnostic interface and via data lines. A method for improved checking of repairs is also presented with the diagnostic tester. The motor vehicle-mounted control devices have program routines for self-diagnostics of the control devices and are capable of storing identified faults in the form of fault codes in reserved memory areas. The diagnostic program which is implemented in the diagnostic tester reads the fault codes out from the reserved memory areas, interprets the fault codes and displays them on a display together with the interpretations. In order to check to what extent repairs which have been performed have been successfully concluded, status polling is carried out using the diagnostic program implemented in the diagnostic tester. During this status polling, the status information of all the fault codes known in the system is interrogated and evaluated. In the process, all the fault codes whose fault setting conditions have either been tested positively or whose test requirements were not present in order to be able to carry out a test are displayed. The fault codes which are to be displayed are firstly stored here in one or more primary first fault memories, read out and then copied into a secondary, second fault memory. This permits the use of the total reset of the primary fault memories which is prescribed in the USA for diagnostic systems without information which is relevant to the checking of repairs in the second fault memory being lost.

A frequency-dividing circuit arrangement is disclosed that includes a divider chain having a plurality of frequency divider stages. The frequency dividers can be changed over between the division ratios 2 and 3. At least that frequency divider that is arranged on the output side of the divider chain has an additional through-switching input that makes it possible to switch through the input signal to the output of the divider stage without influencing the delay-time effects of the divider stage. The advantages of a cascaded 2/3 divider chain, such as a high cut-off frequency, a simple design and the ability to arbitrarily expand, are thus achieved without accepting a lower limit of the range of possible division values.

A circuit arrangement includes a phase locked loop configured to produce a controlled frequency. The phase locked loop has an actuating input and a control loop output, with it being possible to tap off the frequency at the control loop output. In addition, a frequency meter is provided, which is connected to the control loop output of the phase locked loop. The frequency meter is configured to measure the frequency of the phase locked loop. Finally, a computation unit is provided in order to determine a gradient associated with the phase locked loop and generate a correction value based thereon, wherein the correction value is employed to mitigate a deterioration in the loop bandwidth due to variations in the gradient.

A phase regulating arrangement or circuit is disclosed, in which, in addition to a frequency divider, which is arranged in the feedback path of the PLL and, provision is made of a further frequency counter. The frequency counter is configured to be readable and is likewise connected to the oscillator output. The frequency counter drives a control unit that selects a desired frequency band of a multiband oscillator. The phase regulating arrangement or circuit described enables very fast settling in conjunction with low phase noise and good integration possibilities.

Some embodiments relate to a transmitting arrangement that includes a digital to time converter (DTC) with a reference generator and a modulation generator coupled to first and second input terminals thereof. A feedback path, which includes a phase and/or frequency measurement block and a phase and/or frequency correction block, is coupled between an output terminal of the DTC converter and the second input terminal of the DTC. The feedback path can help determine a phase or frequency correction word that can be applied to a modulation control word provided by the modulation generator to tune or correct the modulation control word before it reaches the DTC. In this way, the transmitting arrangement facilitates extremely accurate phase alignment and helping achieve extremely accurate signal transmission.

Embodiments of the present invention create a circuit having a digital-to-time converter with a high-frequency input for receiving a high-frequency signal, a digital input for receiving a first digital signal, and a high-frequency output for the provision of a chronologically delayed version of the HF signal. In addition, the circuit has an oscillator arrangement for the provision of the high-frequency signal, having a phase-locked loop for adjusting a frequency of the high-frequency signal. The digital-to-time converter is designed to chronologically delay the received high-frequency signal based on the first digital signal received at its digital input.

A device is provided for fixing a child seat to a support structure of a motor vehicle, including a plastically deformable holding device, which is fixed to the support structure and has a holding element to which a fixing element, which is attached to the child seat, can be fixed. In order to permit a defined movement of the holding element during deformation of the holding device, the holding device has at least one bending axis along which the holding device can be deformed when a force, such as a tensile force, acts on the holding element.
