Vehicle collision detector

A method for a collision prevention detector to be mounted on a vehicle, comprising:

• transmitting a sequence of transmissions of IR signals, whereby the signals are transmitted in sequences alternating between at least one at the right and to the left positioned LED, when both signals provide are turn return/reflected signal to IR-receiver an object is determined as present within an area from the point where the transmitted signals intersect/cross, whereby the sequencing of signals makes it possible to position a return signal from the object, as one of the signals has to confirm the other signal to provide a warning signal, said detector performing the steps of:
• detecting objects in a near-field zone of the vehicle with a first set of LED's LEDs, and detecting objects beyond said first field in a far-field zone with a second set of LED's LEDs, whereby the two sets of said LED's LEDs are positioned to the right and to the left;
• providing a processor with the vehicle speed and connected to said first and second sets for detection of near- and far-field zones;
• and
• using a comparator connected to or comprised in said processor for comparing the vehicle speed with a pre-determined loss of measured distance by measuring how fast said vehicle approaches said object by closing in from the far-field zone to the near-field zone, whereby an alarm is given through an indicator device mounted on said vehicle alerting a vehicle driver to pay attention to the closing in of an approaching object.

A collision prevention detector comprising:

• a receiver electrically coupled to a processor;
• a first emitter electrically coupled to the processor and configured to emit a first beam;
• a second emitter electrically coupled to the processor and configured to emit a second beam, wherein the first beam and the second beam are configured to intersect at a first zone;
• wherein the processor is configured to sequentially transmit a first message in the first beam and a second message in the second beam and generate a warning signal if the receiver receives the first message and the second message, and wherein the first message and the second message each comprise bits;
• a third emitter electrically coupled to the processor and configured to emit a third beam;
• and
• a fourth emitter electrically coupled to the processor and configured to emit a fourth beam, wherein the third beam and the fourth beam are configured to intersect at a second zone;
• wherein the processor is further configured to sequentially transmit a third message in the third beam and a fourth message in the fourth beam and generate a second warning signal if the receiver receives the third message and the fourth message.
