A detection system for a vehicle, including at least one detection device operable for detecting objects in a detection area. The detection device also includes a first emission antenna, a first reception antenna, and a plurality of extension portions. One of the plurality of extension portions is integrally formed as part of the first emission antenna, and another of the plurality of extension portions is integrally formed as part of the first reception antenna. The first emission antenna generates an emission wave at a predetermined angle which contacts objects in the first detection area and deflects of the objects in the first detection area, and returns to the first reception antenna as a return wave. In an embodiment, the first emission antenna includes at least one Vivaldi wing, and the first reception antenna includes at least one Vivaldi wing.

Vivaldi antenna wings

A device for determining the position of a magnetic element (), the magnetic element being able to be moved in at least two directions relative to a longitudinal axis (A), a first direction (Z) and a second direction (X). The device includes: a position sensor () including two sets of two Hall-effect cells measuring the same magnetic field generated by the magnetic element, a first set along a first axis (B) substantially perpendicular the longitudinal axis (A), and a second set along a second axis (C) substantially parallel to the first axis (B), the magnetic element being moveable relative to the position sensor; first unit () for calculating the position of the magnetic element in the main direction (Z); and second unit () for calculating the position of the magnetic element in the secondary direction (X).

Method for determining the position of a magnetic element on a gearbox selector of an automobile, generating a magnetic field ({right arrow over (V)}), the speed selector moving in two directions with respect to a longitudinal axis, a main direction and a secondary direction, the magnetic element facing a position sensor including three Hall effect cells, includes measuring three voltages (V, V, V) at the respective outputs of the three Hall effect cells oriented in the same direction and positioned as follows: two cells being aligned on a transverse axis perpendicular to the longitudinal axis, the third cell being positioned on the longitudinal axis perpendicularly to the transverse axis, passing through the other two Hall effect cells, 

Method for determining the position of a magnetic element using hall effect linear sensors and associated device

A Hall effect measuring device under the hood of a motor vehicle includes a housing, a Hall effect sensor including a holed magnet and a chip arranged at the Gaussian zero point of the magnet, and a ferromagnetic target including a measurement surface in which the chip is securely attached to the magnet, and defines a measurement plane. The sensor and the ferromagnetic target are arranged to be imparted with a relative motion with respect to one another, the sensor being positioned in the housing and configured to measure the value of the magnetic field of the magnet, vertically in line with the chip, on a measurement axis perpendicular to the measurement plane based on relative translational motion and on relative rotational motion.
