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.

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.

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.
摘要:
Method for obtaining information about an occupying item in a compartment in a vehicle includes obtaining a series of images of the compartment, each image being taken at a different time and at least one of which includes the occupying item, comparing a later obtained image from the series of images to at least one previously obtained image from the series of images to ascertain the presence of differences between the images, and analyzing the differences to obtain information about the occupying item. One way to compare images is to subtract the later obtained image from the previously obtained image to determine which image pixels have changed in value and analyze the changed pixels. This analysis may involve analyzing a leading edge of the changed pixels and/or analyzing a width of a field of the changed pixels.

System for obtaining information about a vehicle or a component therein includes sensors fixed to a frame of the vehicle and arranged to generate and transmit a signal upon receipt and detection of a radio frequency (RF) signal and a multi-element, switchable directional antenna array. Each antenna element is directed toward a respective sensor and transmitter RF signals toward that sensor and receive return signals therefrom. A control mechanism controls transmission of the RF signals from the antenna elements, e.g., causes the antenna elements to be alternately switched on in order to sequentially transmit the RF signals and receive the return signals from the sensors.
摘要:
Vehicular system for determining the presence of an object in a passenger compartment of the vehicle includes a first image receiver arranged at a first location for obtaining a first two-dimensional view of a portion of the compartment, and a second image receiver arranged at a second location for obtaining a second two-dimensional view of the same portion of the compartment, the second image receiver being arranged relative to the first image receiver such that three dimensions of the portion of the compartment are encompassed by the first and second views. A processor receives images from the first and second image receivers and determines whether an object is present in the compartment based on the images. A reactive system, such as an airbag assembly, may be coupled to the processor and controlled thereby based on the determination of whether an object is present in the imaged portion of the compartment.
摘要:
System and method for sensing one or more occupant characteristics of a vehicle occupant in which an electromagnetic energy signal is transmitted toward an occupant location within a vehicle and absorption of the energy signal by a vehicle occupant is detected, if such absorption occurs. An absorption signal indicative of the absorbed energy signal is detected and processed to determine the occupant characteristic(s). Occupant characteristics include the presence or absence of an occupant, size, location, biometric features such as a voice print, a hand print, a finger print, an iris scan and a facial feature, and type, e.g., a child seat. The occupant characteristic may be used to control a vehicular component such as an occupant protection device.
