摘要:
A car navigation device mounted in a vehicle is capable of notifying a driver of an email incoming. Here, information relating to a traveling speed of the vehicle is retrieved. Based on the retrieved information, when the traveling speed of the vehicle is greater than a predetermined speed, notifying the driver of the email incoming is prohibited. This decreases a risk when the driver is notified of the email incoming while driving the vehicle.

A system for monitoring fuel consumption and optimizing refueling of a vehicle. The system includes a fuel level sensor designed to be mounted on a fuel tank. The fuel sensor has a transducer, such as an ultrasonic transducer, for generating a distance signal that represents the distance between the sensor and the surface of the fuel in the fuel tank. A processor coupled to the transducer is programmed to convert the distance signal to a percentage of capacity signal, calculate the volume of fuel within the fuel tank, and create a message that includes information regarding the volume of fuel in the fuel tank. The processor of the fuel level sensor is coupled to a network that may include a dispatch terminal, a fuel optimization server, and a fuel-price-by-location service. The network calculates an optimal location for refilling the fuel tank and a route to travel to the location. It broadcasts a message containing the refueling and route information to the vehicle information system, and devices coupled to the vehicle information system then display the message to inform the driver of the vehicle when and where to refuel.

A sensor device (11) which can be attached at at least two different installation locations in a motor vehicle (10) by at least one attachment device and which has a data output. The sensor device (11) is installed at a predefined installation location in the motor vehicle (10) by attachment to at least one predefined attachment point (13), the attachment point (13) being characteristic of the installation location in such a way that the attachment to the one predefined attachment point (13) generates a predefined electrical effect, and the sensor device (11) is installed at another predefined installation location in the motor vehicle (10) by attachment to at least one other predefined attachment point (14), the attachment to the other predefined attachment point (14) generates a different predefined electrical effect. It is possible to determine the actual installation location of the sensor device (11) by sensing the generated electrical effect.

A method of optimizing traffic content includes providing a traffic flow algorithm (220) coupled to receive a set of solicited navigation route data (210) and a set of solicited traffic data (212) between a starting location (305, 405) and a destination location (310, 410), where traffic flow algorithm (220) is designed to compute a set of optimized traffic content (230) between a starting location (305, 405) and a destination location (310, 410). A set of unsolicited user-defined navigation route data (215) is received and incorporated with set of solicited navigation route data (210) and set of solicited traffic data (212) into traffic flow algorithm (220). A set of optimized traffic content (230) is calculated between the starting location (305, 405) and the destination location (310, 410) utilizing at least the set of unsolicited user-defined navigation route data (215).
摘要:
This invention provides a system and method for mapping parameters of a queue of a traffic congestion, for example, a road congestion. Mapping of the road congestion may include determination of an average length of the road congestion over a time interval, motion rate in the road congestion and average arrival rate to the road congestion. These parameters, in turn, may be used to determine an expected delay in traveling throughout the road congestion as well as trends, i.e., changes with time, in the road congestion, using special radio systems and also existing radio networks such as Public Land Mobile Networks (PLMN) and Private/Public Data Networks (PDN). Examples of PLMN are GSM, IS-54, IS-136, PCS-1900, IS-95, GPRS and EDGE for GSM, WCDMA, cdma 2000, and others. Examples of PDN are Mobitex, CDPD and others. Other networks could be included under these categories since the mapping of road congestion usually consider only very low velocities, and hence PHS, DECT and other similar networks could also be used. The mapping is performed relative to an identified or estimated front end of a queue of a road congestion. The mapping system may construct snapshots of mapping samples received from a small percentage of pre-designated probes, e.g., a small percentage of vehicles equipped with an appropriate receiver and transmitter. The mapping samples are preferably received in response to predefined broadcast control messages sent from the mapping system. The determination of the average length of a road congestion may be based on a direct approach, obviating the need to estimate discrete lengths of the road congestion, in dynamic conditions that include variations in the arrival rate of vehicles to the road congestion and the departure rate of vehicles from the congestion over time.

The invention relates to a traffic management system (TMSYS) including a layered structure of management layers. The system comprises a physical layer (PL) on which the actual traffic takes place. A traffic signalling layer (TSL) controls the traffic on the physical layer (PL) and collects traffic information (TSI) about the vehicle traffic. A traffic control layer (TCL) comprises a packet switched control network (PSCN) for routing packets to correspond or simulate the vehicle traffic. A service application layer (SAL) provides special services to the traffic control layer (TCL) and/or the traffic signalling layer (TSL). A communication layer (CL) is used for communicating the information. Each layer comprises an exchange interface for receiving/transmitting information to one or more of the other layers. The layered structure of the traffic management system allows in particular a flexible adaptation, exchange or extension of functionalities provided in each layer.

A system 10 for detecting sliding of a wheel 12 on a rail 14 includes a roller 16 disposed adjacent the rail 14 so that a wheel 12 travelling along the rail 14 can engage the roller 16, and a tachometer 18 coupled with the roller 16 for providing a rotation signal representative of the degree of rotation of the roller. The system 10 includes a computer 20 which receives the rotation signal from the tachometer 18 and by using an appropriate rotation algorithm calculates the degree of rotation of the roller 16. The computer 20 then compares the degree of rotation with a predetermined range of roller rotations and, if the calculated degree of rotation of the roller is less than predicted by analysis, the apparatus 10 provides a signal indicative of the wheel 12 sliding.

A method for displaying a separation time interval of at least one of a plurality of objects approaching a reference includes estimating a transit time of the at least one of the plurality of objects assigned to a corresponding first path to the reference, determining the separation time interval for the at least one object, and forming a time line axis. The method further includes displaying a representation of the at least one object aligned relative to the time line axis for indicating the estimated transit time, and displaying the separation time interval.
