摘要:
An electronic module for use as a control device in a motor vehicle, includes a plastic-coated electronic circuit with at least one organic HDI circuit carrier. The electronic circuit is disposed on a heat sink and electrically-conductive conductor structures are provided for electrically connecting the electronic circuit to electrical devices or components outside the electronic module. The circuit carrier is thermally and conductively connected to the heat sink, and the electronic circuit and the heat sink are coated in plastic in such a manner that only the rear side of the heat sink lying opposite the circuit carrier is at least partially free of plastic, and at least contact ends of the conductor structures, which make the electrical connection to the electrical devices or components outside the electronic module are free of plastic. A method for the production of the electronic module is also provided.

An electronic component is switched under the control of a pulse-width modulation signal. The electronic component outputs an output signal that is controlled by a control signal. The switching on or off is initiated within a pulse-width modulation cycle period at a level change time by a change of the pulse-width modulation signal. The control signal is set within each PWM cycle period to a first control value between the level change time and a first switching time, to a second control value between the first switching time and a second switching time, and to a third control value from the second switching time until a final gate-voltage value is reached on the gate of the electronic component. Each switching time of a PWM period is determined in dependence on an amplitude value determined during a preceding PWM cycle period, to limit amplitudes of the oscillation of the output signal.

The invention relates to a method for determining a depth map from stereo images. The disparity for a pixel is determined from a discrete quantity of predefined disparity values, said disparity values are distributed over the entire predefined disparity value range and said distribution has at least two different distances between adjacent disparity values.One advantage of the method according to the invention is that it allows only those disparities for which a more precise determination is required to be more precisely calculated.

The invention relates to a method for analyzing trafficability using a computer, said method comprising the following steps: receiving image data of surroundings (10) in front of a vehicle (S10), analyzing the image data to identify different zones (12, 14, 16, 18, 24) in an image of the surroundings (S12, S14, S16, S18, S20); and analyzing identified different zones (16, 18) in terms of trafficability for the vehicle (S22, S24).
摘要:
A method for learning traffic events, the traffic events being transmitted to a data network using vehicle-to-X communication. The traffic events include position data and time data assigned to the traffic events, and the traffic events are stored electronically in the data network. The method is characterized in that an individual storage duration is determined for each traffic event, and the traffic event is deleted from the data network after the storage duration expires. The invention further relates to a corresponding system and to the use thereof.

An electronic system includes a carrier including at least one waveguide feeding, a semiconductor chip including a first surface and a second surface, and an integrated RF circuit, and a cooling element including a backshort. The semiconductor chip is mounted to the carrier such that the first surface faces the carrier. The integrated RF circuit is connected to the at least one waveguide feeding. The cooling element is mounted to the carrier such that the backshort is adjacent one end of the at least one waveguide feeding, and the cooling element at least partially covers the semiconductor chip such that the second surface of the semiconductor chip faces the cooling element.
摘要:
A driver assistance system includes a sensor that detects objects and/or characteristics of objects in the surroundings of a motor vehicle, and an object recognition unit that evaluates data from the sensor to produce object information, and determines a confidence value indicating the probability of accuracy thereof. If the confidence value is greater than a minimum threshold but less than a predefined threshold, then the system displays the object information to the driver, who confirms or rejects it, e.g. by actuating or not actuating an operating element. Upon confirmation by the driver, the system begins or continues to perform a driver assistance function based on the object information. Upon rejection by the driver, the system does not perform or discontinues the driver assistance function based on the object information. If the confidence value exceeds the predefined threshold, then the system autonomously performs the driver assistance function.
摘要:
The present invention relates to a method for recognizing projected information on the carriageway. In particular, the present invention relates to a camera-based driver assistance system which uses image processing methods to automatically recognize dynamic, in most cases colored, symbols or information which is/are projected onto the road by a vehicle ahead, and is able to respond in an appropriate manner based on the recognized symbols. For example, advice can be given to the driver or signals can be transmitted to vehicle devices in order to bring about an appropriate vehicle response. In particular, an emergency braking action or a distance alert can be brought about.

The invention relates to a method for supporting a traffic-light-sequence assistant of a vehicle (10), said assistant detecting the traffic light sequences of traffic lights (11) by means of a camera (1). The invention provides that when traffic lights (11) are detected in the visual range (1a) of the camera (1), the length (L) of the driving path (W) in the direction of the traffic lights (11) is determined by means of a control unit (3), said driving path keeping the camera (1) in the visual range (1a) thereof, and a control signal (St) concerning the length (L) of the driving path (W) is outputted.

The invention relates to a method for assisting in returning a vehicle (10) after leaving a roadway (12), comprising the following steps: receiving data from one or more driving environment sensors (14) of the vehicle capturing the roadway in a region ahead of the vehicle (S10), analyzing the received data for detecting a transition (16) between the roadway and a roadway periphery (18; S12), analyzing the received data for detecting a free space (20) ahead of the vehicle (S14), checking whether the detected transition is noncritical for returning the vehicle to the roadway and issuing a corresponding first signal (22; S16), checking whether the detected free space is sufficient for returning the vehicle and/or whether obstacles (28b) are present on the roadway periphery (18) or the detected transition (16) and issuing a corresponding second signal (24; S18), and generating a feedback signal (26) if the first signal signals that the detected transition is noncritical and the second signal signals that the free space is sufficient or if the second signal signals the presence of obstacles (28b) on the roadway periphery (18) or the detected transition (S20).
