Abstract
Provided is a driving assistance system capable of providing more pieces of information to a vehicle side by using magnetic markers. A driving assistance system (1A) is a system including magnetic markers (1) laid on a travelling road so as to be magnetically detectable and also be able to provide code information to a vehicle side, a vehicle (5) configured to be able to magnetically detect the magnetic markers (1) and also read the code information, and a base station (6) configured to make a reply with corresponding information when receiving the code information from the vehicle (5) reading the code information.
Claims17
A driving assistance system comprising:
- a plurality of magnetic markers laid on a travelling road configured to provide code information to a vehicle, each of the plurality of magnetic markers being magnetically detectable by the vehicle;
- the vehicle comprising
- processing circuitry configured to
- magnetically detect the plurality of magnetic markers,
- read the code information from the plurality of magnetic markers, and
- transmit the read code information to a base station;
- and
- the base station configured to transmit corresponding information corresponding to the code information to the vehicle in response to receiving the code information from the vehicle, wherein
- the processing circuitry of the vehicle is further configured to perform driving assistance control to assist driver's driving by processing the corresponding information received from the base station,
- at least one of the plurality of magnetic markers include a magnet and a radio tag which wirelessly outputs the code information,
- the magnet is a component independent from the radio tag, and the magnet generates a peripheral magnetic field independently from the radio tag,
- the radio tag is a component independent from the magnet, and the radio tag provides the code information to the vehicle independently from the magnet,
- the radio tag is laminated and provided on a surface of the magnet,
- the radio tag and at least a part of the surface of the magnet, on which the radio tag is laminated and provided, are covered by a sheet of a resin mold,
- the magnet has a thickness of less than or equal to 1.0 mm, and
- the magnet has a maximum energy product (BHmax) of 6.4 kJ/m3 or less.
