摘要:
Arrangement for transferring information between a vehicle and one or more transmitters separate from the vehicle includes an antenna mounted on the vehicle and capable of receiving radio frequency waves emitted by the transmitter and containing information, a position determining device for determining the position of the vehicle, and a processor coupled to the antenna and the position determining device and arranged to analyze the waves received by the antenna, determine whether any received waves contain information of interest for operation of the vehicle based on the vehicle's position as determined by the position determining device, and extract the information of interest only from the received waves determined to contain information of interest. The information of interest may be information about the transmitter such as its location, speed, velocity, etc., or information relating to road conditions, weather and the like.
摘要:
Method for transferring information between a vehicle and a transmitter in which a unique pseudorandom noise signal is transmitted by the transmitter in a carrier-less fashion composed of frequencies within a pre-selected band. Information is encoded in the noise signal relating to an identification of the transmitter and a position of the transmitter and the vehicle is provided with a device for extracting the information from the noise signal. The code to use for encoding the noise signal may be selected based on the position of the transmitter so that analysis of the code, or a portion thereof, provides an indication of the position of the transmitter. Information about accidents, weather conditions, road conditions, map data and traffic control devices and about errors in a GPS signal can also be encoded in the noise signals. The transmitter may be at a fixed location or in another vehicle to thereby enable vehicle-to-vehicle communications for the purposes of collision avoidance, intelligent highway applications and the like.

Method for avoiding collisions between a host vehicle and other vehicles in which the position of the vehicles is determined, the vehicles are equipped with a transmitter/receiver, and in the host vehicle, the possibility of a collision involving the host vehicle is assessed by receiving signals from the transmitter/receivers of each other vehicle, analyzing the received signals to extract positional information about the transmitter/receivers from each signal, and when a received signal contains additional information of interest about a possible collision involving the host vehicle, analyzing the extracted positional information to determine whether any signals contain additional information of interest about a possible collision involving the host vehicle. Additional information is extracted only from such signals and analyzed to ascertain whether a collision between the host vehicle and any other vehicles is likely to occur in order to enable action to be taken to prevent the collision, e.g., evasive action.

An arrangement and method for displaying and transferring information between a vehicle and at least one transmitter separate from the vehicle includes an antenna mounted on the vehicle for receiving RF wireless signals emitted by each transmitter, a location determining device for determining the vehicle's location, a display arranged on the vehicle in a position to be viewable by a vehicle occupant and to display representations of the vehicle and other objects in the vicinity of the vehicle, and a processor coupled to the antenna, location determining device and display. The processor performs location-based filtering of signals received by the antenna to determine whether any contain information of interest for vehicular operation, extracts the information of interest from the signals determined to contain information of interest, and displays the location of the transmitter of the signals determined to contain information of interest or the information of interest from the transmitter.
摘要:
System and method for conveying data between vehicles includes a data generating system arranged on a first vehicle to obtain or generate information about the first vehicle or conditions around the first vehicle, a first communications system arranged on the first vehicle and coupled to the data generating system for communicating with a wireless Internet service provider (ISP) and a second communications system arranged on a second vehicle and communicating with an ISP. The first communications system enables the information obtained or generated by the data generating system to be transmitted via the Internet to the second communications system. The first and second communications systems can communicate with the same ISP or different ISPs linked to one another.
摘要:
Method and arrangement for setting a speed limit for vehicle travelling on a road includes monitoring conditions of the road, determining a speed limit for travel of vehicles on the road based on the monitored conditions, and transmitting the determined speed limit to the vehicles to thereby notify operators of the vehicles of the determined speed limit. Monitoring conditions of the road may entail monitoring weather conditions around the road, monitoring visibility for operators of the vehicles on the roads, monitoring traffic on the road, monitoring accidents on the road or emergency situations of vehicles on the road and/or monitoring the speed of vehicles travelling on the road and a distance between adjacent vehicles.
摘要:
In or for a vehicle, an arrangement for measuring weight of an occupant of a seat connected to a floor of the vehicle via a slide mechanism, the floor, in part, defining a passenger compartment of the vehicle. A support structure extends between the slide mechanism and the seat. A force sensing device is coupled to the support structure and configured for measuring force in the support structure indicative of weight applied by the occupant to the seat. The weight may be used for component control.
摘要:
RFID and sensor assemblies for vehicles in which an interrogator transmits RF signals and receives responsive RF signals from the RFID assemblies. Each RFID assembly includes a sensor and an RFID switch which receives an RF signal from the interrogator and upon receipt of a signal containing its identification, enables transmission of a signal from the sensor from which a property being monitored by the sensor is determinable. The sensor may be a SAW sensor which modifies a received wave as a function of the property being monitored by the sensor and thus transmits a modified wave. Each RFID assembly may include an antenna arranged to receive signals from and provide signals to the interrogator. The RFID switch is arranged to connect or disconnect the sensor from a circuit dependent on whether the antenna receives a particular signal associated with the RFID assembly.

Accident avoidance system onboard a host vehicle includes a position determining system for determining position information for the host vehicle based on signals received from a plurality of satellites, a transmitter for broadcasting the position information for the host vehicle to locations remote from the host vehicle, a receiver for receiving a traffic information broadcast from an infrastructure system including vehicle position information received from position-reporting vehicles and vehicle position information received from an active position determining system that acquires position information for non-position-reporting vehicles. and an accident risk warning system. The risk warning system alerts an operator of the host vehicle of a risk of an accident involving the host vehicle based on the vehicle position information for the host vehicle and map data representing a roadway that the host vehicle is approaching or traveling on including edges or lane boundaries of the roadway.

Electronic system in a vehicle includes crash sensor systems each arranged to sense a crash involving the vehicle and occupant protection systems each including an occupant protection device arranged to protect an occupant in the event of a crash involving the vehicle. The crash sensor system(s) and the occupant protection system(s) are connected to a bus and supplied with power by the bus and communication through the bus. Each occupant protection device is actuated in the event of a crash involving the vehicle as sensed by a crash sensor system. Each occupant protection system may include a power supply for providing power to enable actuation of the occupant protection device, diagnostic circuitry for self-diagnosis, an occupant sensor and a controller for controlling actuation of the occupant protection device based on a signal received from a crash sensor system over the bus, and data from the occupant sensor.
