Definitions
- the invention relates to an environment detection system according to the preamble of claim 1.
- environment detection systems will be used in particular in the future
- Automotive area used for distance control, lane warning and guidance or to initiate measures in the event of an impending collision.
- the transmitters each generate an illuminated target area in accordance with a predetermined scatter, into which a receiver is directed and detects the reflections from the target area.
- the transmitter and receiver are usually located in the immediate vicinity.
- the target area is approximately conical due to the scattering angle.
- the transmitters In order to record the entire lane, the transmitters must be spaced accordingly. While in the area of large distances from the vehicle the conical target areas touch each other with a corresponding distance of the transmitters, an area that cannot be detected arises in the near area.
- a third transmitter and a correspondingly aligned receiver would also have to be provided, as can be seen in FIG. 1.
- the object of the invention is to present an alternative environment detection system which enables the most comprehensive detection possible. This object is achieved by the features of claim 1. Advantageous further developments can be found in the subclaims.
- the invention is based on the idea of using appropriate optical means to guide at least some of the waves emitted by a transmitter into the third target area to be detected and to detect reflections occurring there from the spaced-apart receiver, i.e. ultimately to implement cross-coupling of the transmitters and receivers ,
- FIG. 1 shows an environment detection system in a motor vehicle, as is known to be used in the future for distance control or pre-crash detection or other areas of application. It has at least two transmitters S1, S2 of electromagnetic waves, which in this example are arranged on the right and left side of the vehicle with the transmission direction in the direction of travel. Correspondingly, two receivers E1, E2 are provided for receiving reflections of the emitted waves, the first transmitter S1 with the first receiver E1 being aligned with a first target area Z1 and a second transmitter S2 with a second receiver E2 with a second target area Z2.
- the front area in front of the vehicle is completely detected at least from a certain distance. In the near area, because of the cone-shaped target areas that diverge in the direction of travel, an area that is not covered remains.
- At least the first transmitter S1, but preferably both transmitters S1 and S2 have optical means which at least temporarily guide at least some of the waves emitted by this transmitter S1 into the third target area Z3 and at least the second receiver E2, preferably also the first receiver E1, has optical means which at least temporarily direct reflections of the waves emitted by the first transmitter S1 into the third target area Z3 onto the second receiver E2.
- Appropriately adapted lenses, prisms or lenses are considered as optical means.
- These optical means for illuminating and capturing the third target area Z3 can either be temporarily arranged in front of the transmitters and receivers, so that a cyclical change occurs between capturing Z1, Z2 and Z3.
- the optical means are preferably arranged permanently in front of the first transmitter S1 and the second receiver E2 and in this case only direct a part of the emitted waves to the target area Z3 or from this target area Z3 to the receiver E2.
- the first transmitter S1 then transmits, the first receiver E1 detecting the first target area Z1 and second receiver E2 the third target area Z3, while the second transmitter S2 is inactive, as outlined in FIG. 2.
- the second transmitter S2 transmits, the second receiver E2 detecting the second target area Z2.
- the first receiver E1 can also detect the third target area (Z3) during the second operating phase. Then the third target area is recorded twice as often as the first and second target area, which is also desirable, however, since the third target area encompasses the immediate vicinity of the vehicle and the detection there is particularly time-critical.
- the third target area Z3 at least partially captures a near area lying between the first and second target areas Z1, Z2, but can certainly overlap this.
- the timing of the transmitters and receivers and the evaluation of the signals from the receivers and the assignment to the target area is carried out in a central evaluation unit 1, which then makes the processed signals available to the corresponding application units.
