In an apparatus for the transfer of information in motor vehicle traffic between a fixed-position transmitter-building element near a roadway and a receiver arranged in a vehicle, the transmitter-building element emits a coded information signal and the receiver of the vehicle driving past the transmitter-building element displays information from the information signal in the vehicle. In order to make shielding measures unnecessary, with an uncomplicated supply of energy to the transmitter-building element and small construction costs therefor, the transmitter-building element (1) is built into roadway pavement (12). The energy necessary for transmitting the information signal is received by the transmitter-building element (1) from the vehicle (13) which is driving above it. The receiver (4, 15, 16) has an antenna arrangement (14) which is arranged in a floor area of the vehicle (13) to transfer the necessary transmitting energy to the transmitter-building element (1) and receive the emitted information signal from the transmitter-building element (1).
The present invention discloses a traffic caution apparatus which may distinguish the running direction of vehicles. The apparatus includes a transmitter and a receiver. The transmitter an ultrasonic transmitting unit and a FM stereo transmitting unit. The receiver includes a FM stereo receiving unit, a decoding unit, an ultrasonic receiving unit, a monolithic processor, an analogy switch, a speed recording/reproducing unit, a given voltage unit. The apparatus uses ultrasonic wave to distinguish running direction and speed of vehicles, and can send caution speech information with accuracy to a vehicle whose speed must be limited. The apparatus has expandable function which may provide other caution information, large number of travel and business information to vehicles. This apparatus may substitute travel caution signs.
A guidance system includes a vehicle-mounted apparatus. A sensor-signal input unit inputs a vehicle-sensor signal for acquiring a vehicle status. A determining unit determines a movement of the vehicle on the basis of the vehicle-sensor signal inputted from the sensor-signal input unit. A guidance-information acquiring unit acquires guidance information from an external apparatus through a communication apparatus mounted on the vehicle. An information selecting unit selects guidance information acquired by the guidance-information acquiring unit depending upon a vehicle movement determined by the determining unit. An output unit outputs guidance information selected by the information selecting unit.
A system for marketing real estate includes a property data device and a personal data device. The property data device is to be located in the vicinity of a real estate property, and the personal data device is to be provided to a user. The property data device is operable to transmit the property information data, and the personal data device operable to receive and store the property information data transmitted by the property data device.
A vehicle control method for use in an automatic driving system which transmits drive support information stored in each of markers buried in a road at regular intervals, to a vehicle which passes the marker, in order to support driving of the vehicle, comprising the steps of storing, in the marker, positional information indicative of the position of the marker, and at least one of road information indicative of the state of the road and control information concerning the speed and traveling direction of the vehicle, and transmitting, to the vehicle, the positional information and the at least one of the road information and the control information, which are used as the driving support information.
An electronic speed limit notification system comprises a transmitter for transmitting speed limit information ("SLI"), and a receiver for receiving said transmitted SLI, wherein said receiver can be physically located in a vehicle. The SLI comprises one or more speed limits, wherein each speed limit is the maximum or minimum legal speed for specific vehicles on a specific segment of a specific road traveling in a specific direction.
