Gate safety system for preventing collisions between a vehicle and a gate

A gate safety system for preventing collisions between a vehicle and a gate, having:

• a gate module, comprising:
• a gate antenna unit, having at least one first gate antenna implemented for mounting in a predetermined spatial relationship to a gate frame of the gate, and for generating a first three-dimensional electromagnetic field,
• a gate processing unit connected to the gate antenna unit and adapted for defining a first gate warning zone for the gate, the first gate warning zone representing a sub-region of the first electromagnetic field, the gate processing unit being adapted, by the gate antenna unit, for determining whether a vehicle module matched to the gate antenna unit is present within the first gate warning zone, wherein the gate processing unit is configured to send a geometry configuration of the first gate warning zone to the vehicle module, such that the vehicle module processes the geometry configuration of the first gate warning zone to determine whether the vehicle module is present within the first gate warning zone, and
• a gate interface for connecting the gate module to a controller of the gate;
• wherein the gate safety system further comprises the vehicle module, the vehicle module comprising:
• a vehicle antenna unit, having at least one first vehicle antenna implemented for mounting in a predetermined spatial relationship on the vehicle, and for generating a second three-dimensional electromagnetic field, and
• a vehicle processing unit connected to the vehicle antenna unit and adapted for defining at least one first vehicle warning zone for the vehicle, representing a sub-region of the second electromagnetic field, wherein the vehicle processing unit, in response to receiving the geometry configuration of the first gate warning zone, is adapted, by the vehicle antenna unit, for determining whether the gate module matched to the vehicle antenna unit is present within the first vehicle warning zone, wherein the vehicle processing unit is further adapted for determining a trajectory signal that identifies a probable movement path of the first vehicle, and wherein the vehicle processing unit, in response to determining that the gate module is present within the first vehicle warning zone, is set up for sending a configuration of the first vehicle warning zone and the trajectory signal to the gate module,
• wherein the gate processing unit is further set up, based on the received configuration of the first vehicle warning zone and the trajectory signal, for determining a direction of travel of the first vehicle relative to the gate,
• wherein the gate processing unit is further set up to determine, based on the direction of travel of the first vehicle, whether the first vehicle is moving toward the gate, moving toward the region to the right or left of endpoints of the gate, moving generally parallel to the gate, or moving away from the gate, and
• wherein the gate processing unit is further set up to provide an opening signal to the gate interface based on the first vehicle moving toward the region to the right or to the left of the endpoints of the gate.
