摘要： A user discrimination control system controls functionality made available by a vehicle infotainment device by reducing functionality provided to the driver while allowing enhanced functionality to another passenger in the vehicle. The system includes a human machine interface located in a vehicle for allowing an occupant to interface with the infotainment device. A passenger detection sensor senses a condition indicative of a passenger other than the driver interfacing with the human machine interface. A video imaging system detects a driver distraction condition. A controller controls functions made available by the infotainment device by allowing one of first and second levels of functionality based on the sensed conditions.

摘要： A seat assembly is provided that can be sat upon by an occupant that detects the weight of the occupant. The seat assembly includes a seat cushion, a rotary sensor, and a linkage having a tip. The seat cushion deforms in response to the weight. The rotary sensor has a shaft that rotates about an axis and has an electrical output that is proportional to the angle of rotation of the shaft. The linkage underlies the seat surface and connects the seat surface to the shaft of the rotary sensor. As weight is placed on the seat the seat cushion deforms in response to the weight moving the tip and the linkage. The movement of the linkage rotates the shaft, which in turn, provides an electrical output that is proportional to the weight.

摘要： A universal, compartment-wide system identifies the presence and position of occupants of a multi-place vehicle by utilizing the occupants to conduct and radiate place-specific radio frequency signals that are received at various locations in the passenger compartment. The place-specific radio frequency signals are developed by low power transmitters disposed in the various seat/place locations, and a receiver disposed at a central location that is remote from the transmitters receives and decodes the signals radiated by the occupants to determine the number and location of the occupants. Additional receivers may be installed in specified regions to detect occupant intrusion into such regions, and in various control panels to assess driver distraction and to tailor the functional content and capability depending on whether a driver or non-driver is interacting with the control panel.

摘要： An image based object detection system and method having a range finder are provided. The system includes an illuminator located on a vehicle to generate an illumination beam in a coverage zone relative to the vehicle. The system also includes an optics device spaced from the illuminator for collecting reflected illumination from one or more objects in the coverage zone and an imager comprising an array of pixels for receiving images from the coverage zone via the optics device. The imager captures images from the coverage zone and the collected reflected illumination from the objects in the coverage zone. The system further includes a processor for processing the received images and the reflected illumination signals. The processor determines range to an object in the coverage zone based on a location of the pixels in the imager detecting the reflected illumination.

摘要： A capacitive load cell apparatus includes upper and lower capacitor plates and an intermediate dielectric in the form of a synthetic knit spacer material having upper and lower fabric layers interconnected by an array of deflectable synthetic fibers. When occupant weight is applied to the seat, the synthetic fibers deflect to locally reduce the separation between the upper and lower capacitor plates, and the consequent change in capacitance is detected as a measure of the applied weight. The load cell or just the dielectric may be encased in a polymeric sheath to prevent intrusion of foreign matter, and a fluid such as silicone may be dispersed in woven dielectric.

摘要： A fluid-filled seat bladder assembly includes multiple capacitive sensing elements for detecting variation in bladder deformation due to occupant weight. The bladder is defined by upper and lower elastomeric sheets that are peripherally sealed by welding, and the capacitive sensors are defined by metalized films adjoining the upper and lower elastomeric sheets. The bladder fluid separating the upper and lower metalized films acts as a dielectric material, and the capacitance or electric field coupling of each sensor increases when the separation between the respective upper and lower films decreases due occupant seat weight. The cumulative change in capacitance or electric field coupling reflects the total seated weight, and the individual capacitance or electric field coupling changes provide a profile of the pressure distribution across the seat for improved occupant classification. The metalized films may be located exterior of the bladder, or may be are formed on interior surfaces of the upper and lower elastomeric bladder sheets.

摘要： A vehicle crash event is detected and characterized based on the transmission of acoustical shear waves through the vehicle frame. At least three, and preferably four or more, acoustical emission sensors longitudinally and laterally distributed on the vehicle frame produce acoustical signals that are processed to extract the shear wave energy due to impacts. Since shear waves are non-dispersive and travel through the vehicle frame at a known velocity, they can be detected in any part of the frame. The extracted shear wave signals are used not only to judge the severity of the impact, but also to characterize the type of crash and determine the direction of the impact based on when the shear wave is detected by each of the acoustical emission sensors.

摘要： The capacitance of a shielded capacitive load cell is determined so as to minimize the effect of stray or parasitic capacitance between the load cell and other objects including the shield. The load cell conductors are coupled across input and output terminals of an operational amplifier that is tied to a reference voltage. A constant current is applied to the load cell, and the resulting rate of change in voltage at the amplifier output is measured as a representation of the load cell capacitance. In a vehicle seat sensor application including an electromagnetic interference shield between the load cell and the seating surface, the amplifier output is coupled to the load cell electrode furthest from the shield, the amplifier maintains the other load cell electrode at a virtual reference voltage, and the shield is tied to the reference voltage.
