In a device for predictable exposure control of a vehicle camera, a first vehicle camera has a visual field directed to the side or to the rear, and a second vehicle camera has a visual field directed to the front. A method involves recording second image data from the outer front surroundings by the second vehicle camera, detecting a region having altered brightness within the second image data, determining a required change of an exposure value based on the second image data, to compensate for a brightening or darkening that occurs when the vehicle enters the region having altered brightness, and transmitting the changed exposure value to the first vehicle camera such that, upon entry into the region having altered brightness, the first vehicle camera records first image data based on the changed exposure value.

Method and device for predictable exposure control of at least one first vehicle camera

In a method of determining the distance of an object (), a polarization-modulated transmission light beam (LS) is reflected at the object () and is received as a reception light beam (LE) by a polarization analyzer, and the output signal thereof is fed to an evaluation unit (A) for determining the distance. The polarization-modulated transmission light beam (LS) is generated by at least two light sources (D, D, D) which emit differently polarized light beams (L, L, L), wherein the light sources (D, D, D) are each respectively operated with a distinct defined mark-space pattern (M, M, M, M, M, M). The polarization analyzer has polarization filters (P, P, P) corresponding at least to the number of light sources. The respective polarization plane of each one of the polarization filters is correspondingly adapted to a respective polarization plane (E, E, E) of the light beams (L, L, L).

A method for controlling a vehicle may include sensing the presence of a switch-off signal indicative of a command to switch off an ignition of a drive assembly of the vehicle, measuring a voltage value of an on-board power system voltage in an on-board power system of the vehicle in response to sensing the switch-off signal, and comparing the measured voltage value to a predetermined voltage threshold value. If the measured voltage value exceeds the predetermined voltage threshold value, the method may include switching an assistance system of the vehicle into an emergency operating state.

For monitoring the function of a driver assistance system, the environment of a vehicle is detected by at least one sensor, sensor data of the environment is generated, and at least one measurement variable is determined from the sensor data and is compared to reference values for the measurement variable to monitor the function of the driver assistance system. The result of the function monitoring is subsequently output and/or stored in accordance with the result of the comparison.

Previously in a bus system, voltage signals were transmitted from the central unit to the modules, which could reply thereto by variation of the current input. A disadvantage thereby is the relatively high susceptibility to interference of the current input, which itself already must be kept relatively small due to the energy consumption, as well as the correspondingly high effort and expense for an error-free recognition of the signals transmitted from the modules in the central unit. It is now suggested, that the modules also answer to the central unit by means of voltage signals superposed on the direct supply voltage, whereby for the time duration of the signal transmission by the modules, the central unit provides the direct supply voltage to the bus line over a resistor, so that the voltage signal of the module can be detected in the central unit on the bus line on the side of the resistor facing away from the direct supply voltage. A preferred application for bus systems in motor vehicles, especially for a sensor data bus, is provided.

A method for having the control unit access the measured data of individual sensors flexibly over time, and includes providing for the control unit to transmit a request message to the sensors, and having each sensor, by comparing the request message with its own address, derive whether and in what time slot, it should transmit its measured data to the control unit.

An arrangement for generating digital signals on first and second bus lines is tolerant of most line faults, and includes modules connected to both lines, an upper switch between a first potential and the first line, a middle switch between the two lines, and a lower switch between the second line and a second potential lower than the first potential. The switches are controlled to generate digital signals as the potential difference between the two lines. If a fault potential (e.g. a short to ground or other potential) arises on one line, then the switches drive the non-faulty line to provide the required signals relative to the fault potential on the faulty line. Closing the middle switch ensures that the two lines are at the same potential for a low signal. This arrangement is for is signaling in various bus systems, e.g. in vehicle occupant protection systems in motor vehicles.

A pyrotechnical ignition system with integrated ignition circuit for an occupant restraint system for motor vehicles includes electrical components for triggering or communication functions integrated therein, a capacitor arrangement, having a flat non-conductive external surface is used as a substrate or carrier element on which the other components are directly arranged and carried. A conductor structure linking the components can be formed by insertable metal parts that are arranged in the housing and project into the holding chamber in which the capacitor arrangement and the circuit component are arranged, and make contact with contact zones on the upper side of the circuit or the capacitor arrangement. The conductor structure may be a printed-conductor structure that is precipitated on non-conductive external surfaces of the capacitor arrangement, and the lateral surfaces thereof, connect the upper and the lower sides of the ignition capacitor as well as the individual capacitor electrodes within the capacitor arrangement to form one or several capacitors, in particular the ignition capacitor. The ignition bridge layer is situated on the capacitor arrangement or on the circuit.

A passenger protection system is triggered directly at least when a second stage is reached among at least two different stages of an accident hazard an/or accident force, determined in accordance with sensor signals. Already when a first accident hazard and/or accident force stage is reached, at least an indirect trigger command is sent to individual passenger protection systems, a specified time interval is started, and, in the event of the second accident hazard and/or accident force stage not being reached within the specified time interval, a cancel command is sent to cancel the indirect trigger command. On receipt of such an indirect trigger command the passenger protection systems also start a relevant time interval, and in the event of the cancel command not being received on expiry of the relevant time interval, they automatically activate the triggering of the passenger protection systems.

Process for triggering passenger protection systems

An unintended triggering of a safety device, such as an airbag in an occupant protection system, especially in motor vehicles is prevented by storing already during manufacturing of the module or modules, a blocking information in a memory location of the module or modules. The blocking information is preferably temporarily stored in place of a rated information, which is then overwritten when the module has been installed in the protection system for activating the system. In addition, the module is protected against electromagnetic and/or electrostatic disturbances at the input to the bus system.

Control method and module for occupant protection systems with an action to prevent premature triggering

Information data and energy are transmitted from a central control to control modules through a bus system in an occupant protection system including occupant protection devices such as airbags. In order to avoid overloading the protection system due to an immediate recharging of an energy storage member after that member triggers an occupant protection device, such recharging is suppressed or interrupted, preferably until a reset command signal is received by the respective control module from the central control.
