摘要:
Vehicle seat including a seat portion including a container having an interior containing fluid and a mechanism, material or structure therein to restrict flow of the fluid from one portion of the interior to another portion of the interior, a back portion arranged at an angle to the seat portion, and a measurement system arranged to obtain an indication of the weight of the occupant when present on the seat portion based at least in part on the pressure of the fluid in the container. The weight of the occupant can be used to control components in the vehicle or the seat itself.

Vehicle with tire monitoring capabilities includes at least one wheel, each including a rim, a tire mounted on the rim, a sensor system for sensing angular, radial, tangential and/or lateral acceleration of the tire and providing acceleration signals based thereon, and an antenna arranged on the rim or tire and coupled to the sensor system for communicating data about the sensed acceleration. A processor receives acceleration signals provided by the sensor system and determines the existence of an anomaly in the tire based thereon. When arranged on the wheel, the processor provides a signal indicative or representative of the determination of the existence of the anomaly via the antenna to a receiving antenna which conveys it to a reactive system. The reactive system may provide a visual and/or audible warning to the driver of the vehicle or to personnel at a vehicle or tire monitoring facility.

Security system and method for monitoring vehicular compartments includes at least one optical image receiving unit arranged to receive optical images of a compartment of the vehicle, e.g., from at least a portion of the face of a person located at a driver's station in a passenger compartment of the vehicle, and produce image signals therefrom and a processor including an electronic facial-recognition system coupled to the optical image receiving unit(s) responsive to the image signals and controllably coupled to the enabling system, and an electronic storage device coupled to the facial-recognition system to store a set of image signals. The facial-recognition system enables ignition of the vehicle system only if signals representative of select characteristics of a scanned face of the person derived from the image signals produced by the optical image receiving unit(s) match a member of a set of signals stored in the electronic storage device. Each member representative of select characteristics of the scanned face of an authorized operator.
摘要:
Weight sensor for determining the weight of an occupant of a seat including a bladder arranged in a seat portion of the seat and including material or structure in an interior thereof which constrains fluid flow therein and one or more transducers for measuring the pressure of the fluid in the bladder. The material or structure might be open cell foam. The bladder may include one or more chambers, and if more than one chamber is formed, each chamber can be arranged at a different location in the seat portion of the seat.
摘要:
Vehicle including a system for obtaining information about an occupant in a compartment in the vehicle includes illuminating an area of the compartment in which the occupant is expected to be situated with infrared illumination, the infrared illumination being generated from at least one common source and being simultaneously directed from each common source in multiple directions into the area of the compartment in which the occupant is expected to be situated. Infrared receivers receive infrared waves from the area of the compartment in which the occupant is expected to be situated after illumination of the area of the compartment and generate images of the area of the compartment. A processor analyzes the received infrared waves and obtains information about the occupant therefrom when the occupant is situated in the compartment. One or more vehicular components may be controlled based on the obtained information.
摘要:
Method for determining the position of the occupant in a seat having a bottom portion on which the occupant sits and a back portion situated at an angle to the bottom portion including arranging a bladder having at least one chamber in the bottom portion, measuring the pressure in each chamber, and determining the position of the occupant based at least on part on the measured pressure. Pressure may be measured by arranging at least one transducer in association with each chamber. If the bladder comprises a plurality of chambers, each chamber can be arranged at a different location in the bottom portion and the weight distribution of the occupant determined based on the measured pressure in the chambers. In this case, a respective transducer may be arranged in association with each chamber.
摘要:
System and method for preventing accidents between first and second vehicles at intersections in which the absolute position and velocity of the first vehicle are determined, map data relating to edges of lanes of roadways, edges of roadways and the location of traffic control devices is stored in a map database and the status of the traffic control devices is provided to the first vehicle when needed. The absolute position and velocity of the second vehicle are determined and a collision between the first and second vehicles is predicted based on the position and velocity of the first and second vehicles, the map data and the status of the traffic control devices. An action or changing operation is initiated by a reactive component or system in the first and/or second vehicle when a collision is predicted.
摘要:
Method for obtaining information about objects in an environment around a vehicle in which infrared light is emitted into a portion of the environment and received and the distance between the vehicle and objects from which the infrared light is reflected is measured. An identification of each object from which light is reflected is determined and a three-dimensional representation of the portion of the environment is created based on the measured distance and the determined identification of the object. Icons representative of the objects and their position relative to the vehicle are displayed on a display visible to the driver based on the three-dimensional representation. Additionally or alternatively to the display of icons, a vehicular system can be controlled or adjusted based on the relative position and optionally velocity of the vehicle and objects in the environment around the vehicle to avoid collisions.
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:
Sensor assembly capable of obtaining and providing a measurement of a physical quantity, e.g., measurement of temperature and/or pressure of a vehicular tire, includes an antenna capable of receiving a radio frequency signal, a radio frequency identification (RFID) device coupled to the antenna, a sensor coupled to the RFID device arranged to generate a measurement of the physical quantity or quantities, and a switch coupled to the RFID device and arranged to connect or disconnect the sensor from a circuit with the antenna dependent on whether the antenna receives a particular signal associated with the RFID device. When the antenna receives the particular signal associated with the RFID device, the RFID device causes the switch to close and connect the sensor in the circuit with the antenna to enable the measurement generated by the sensor to be directed to and transmitted by the antenna.
