The invention relates to an imager module (1) for a vehicle camera, wherein the imager module (1) at least comprises: a lens holder (3), a lens (4) mounted in the lens holder (3), a flexible conductor device (2) with leads (10), and an image sensor (5), which is in electrical contact with the leads (10) of the flexible conductor device (2) and has a front side with a sensitive area, wherein the image sensor (5) is in electrical contact with the leads (10) by way of stud bumps (6) provided on its front side (5b) by means of the flip-chip technique. It is provided here that the lens holder (3) has a plastic part (17), in particular an injection-moulded part, with a tube region (3a) for receiving the lens (4) and a fastening region (3b) having an underside (3c), and the flexible conductor device (2) is attached to the underside (3c) of the fastening region (3b) in a material-bonded manner, and a non-conductive adhesive region (20) is formed between the front side (5b) of the image sensor (5) and the flexible conductor device (2), around the stud bumps, preferably to form a tensile stress. Preferably, an insert (14) is mounted here in the plastic body.

An ultrasonic sensor is described having a housing which has a circumferential side wall and a base surface. A transducer element for generating ultrasonic vibrations is mounted on the base surface. The side wall includes a lower side wall section, in which the side wall has an essentially rotationally asymmetrical profile in a plane parallel to the base surface, and an upper side wall section in which the side wall changes to an essentially rotationally symmetrical profile toward an upper edge of the side wall. In other respects, the present system provides a parking assistance system for a vehicle, having a control unit and such an ultrasonic sensor, as well as a method for manufacturing an ultrasonic sensor.

The invention relates to a method and a device for measuring distance and relative speed of a plurality of objects by means of an FMCW radar. Transmission signals are emitted with temporarily linear ramp flanks and the receiving signals reflected on objects are received and mixed with the transmission signals. A combination of distance and relative speed values is associated with the mixer output frequencies of every frequency ramp for every object. The points of intersection of a plurality of distance and relative speed combinations is used to determine the distance and the relative speed of a possible object. Due to ambiguities, the possible objects can be dummy objects or real objects. The dummy objects due to ambiguities are eliminated randomly in the subsequent measuring cycle.

The invention relates to a method for generating HF signals for determining the distance and/or the speed of an object. The inventive method comprises the steps of: generating a pulsed modulated signal (6') from a first signal (3) and a second signal (4) in a signal generating device (31; 1, 2, M1, 7, 8); transmitting the pulsed signal (6') by means of a transmitting device (20) in the direction of an object (40); receiving a pulsed signal (6'') reflected by the object (40) by means of a receiving device (21); generating a pulsed demodulated signal (4'') from the received signal (6'') and the first signal (3) in a first signal processing device (32; M2, 15); and generating a coherent signal (23) from the pulsed demodulated signal (4'') and the second signal (4) and of a non-coherent signal (22) from the pulsed demodulated signal (4'') in a second signal processing device (33; M3, 16, 17, 18). The invention also relates to a device for generating HF signals for determining the distance and/or the speed of an object.
