Abstract:
Vehicular on-board energy generating system includes a coil and a magnet movable in a passage of the coil during movement of the vehicle such that the movement of the magnet relative to the coil causes generation of electricity. The coil may be wrapped around a cylinder, and its passage may include a chamber defined by the cylinder. An energy storage device is coupled to the coil and arranged to receive and store the generated electricity. One or more sensors can additionally or alternatively be coupled to the coil and arranged to receive and use the generated electricity. A control module can also be coupled to the sensor and arranged to control a component in the vehicle based at least in part on data provided by the sensor.
Abstract:
Method for obtaining information about an occupant of a vehicle for the purpose of controlling a component of the vehicle including arranging a sensor in connection with a seat upon which the occupant is situated, determining weight of the occupant via the sensor when the occupant occupies the seat, and classifying the occupant based on the determined weight, i.e., it may be based on other characteristics of the occupant or seat in addition to the determined weight. Classification of the occupant is used in the control of the component. Method for controlling deployment of an airbag of a vehicle includes arranging a sensor in connection with a seat upon which the occupant to be protected upon deployment of the airbag is situated, determining weight of the occupant via the sensor when the occupant occupies the seat, and suppressing deployment of the airbag based on the determined weight.
Abstract:
Method for controlling a HVAC system in a vehicular compartment includes monitoring temperature of an occupant in the compartment from a location apart from the occupant, and controlling the HVAC system based on the monitored temperature. Occupant temperature may be monitored by infrared sensors, each arranged in an orientation to receive electromagnetic radiation from one or more seating locations in which occupants are likely to be situated. The temperature in each seating location is independently monitored. The HVAC system is controllable for each seating location based on the monitored temperature in that area. When monitoring of temperature in an area in which a driver of the vehicle is likely to be situated indicates presence of the driver, and no other areas indicate presence of a human occupant, the HVAC system is controllable such that all heat or air-conditioning provided by the HVAC system is directed to the driver.
Abstract:
Side impact airbag system for a vehicle includes a side airbag arranged to deploy along a left or right side of the vehicle and an electronic crash sensor. The electronic crash sensor includes a housing, a mass arranged within the housing to be movable in a lateral direction relative to the housing in response to lateral accelerations of the housing, and a control mechanism for controlling deployment of the side airbag and which is responsive to the motion of the mass only in the lateral direction. The housing is mounted in such a position and a direction as to sense an impact into a side of the vehicle resulting in lateral acceleration of the housing. The electronic crash sensor may generate a signal representative of the movement of the mass.
Abstract:
Vehicle including a crash sensor system arranged to determine a crash condition involving the vehicle which might cause injury to a vehicular occupant, at least one module each including an occupant protection device actuatable upon determination of a crash condition in order to protect the occupant from injury during the crash, and a vehicle bus to which the crash sensor system and module(s) are connected. The crash sensor system generates a signal upon a determination of a crash condition and directs the signal over the bus. Each module is arranged to actuate its occupant protection device in consideration of the signal. The signal might be directly sent to the module from the crash sensor system or sent to a control module which processes it and in turn generates a signal to be directed via the bus to the module(s).
Abstract:
Vehicular seat assembly includes a seat having a bottom portion and a back portion coupled at an angle to a rear portion of the bottom portion, a support structure arranged at least partially under the seat and to support the seat on a substrate at a plurality of locations including two rearward locations on opposite lateral sides of the seat and at least one forward location, and a weight measuring system arranged in connection with the support structure for determining an approximate weight of an occupying item of the seat. The weight measuring system consists of only one or two sensors, e.g., strain gage sensors, arranged at the rearward locations or only one or two sensors arranged at the forward location(s). Each sensor provides data relating to the force or pressure being applied at the respective location which is used to derive the approximate weight of the occupying item.
Abstract:
Method for determining weight of an occupying item of a seat in a vehicle having a seat cushion assembly and a seat back assembly defining a contact surface adapted to be in contact with the occupying item of the seat in which a support structure is arranged underneath the seat cushion assembly to support the seat on a substrate in the vehicle. The support structure transfers a force exerted by the occupying item on the support structure to the substrate. At least one strain measuring transducer is mounted at a respective location on the support structure to provide a measurement of the strain in the support structure at the location at which it is mounted. The weight of the occupying item of the seat is determined based on the strain in the support structure measured by the strain measuring transducer(s).
Abstract:
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.
Abstract:
Sensor system for sensing pressure applied to a seat by an occupant of the seat and for controlling deployment of an airbag which includes a bladder defining a chamber and which is adapted to be arranged in a seat portion of the seat, and a pressure sensor for measuring a pressure in the chamber. Deployment of the airbag is controlled based at least in part on the pressure in the chamber measured by the pressure sensor. A control module may be provided to control deployment of the airbag so that when the pressure sensor generates a signal based on the measured pressure in the chamber and provides the signal to the control module, the control module controls deployment of the airbag based on the signal.
Abstract:
Method for controlling deployment of an airbag into a passenger compartment of a vehicle including detecting a position of an occupant whose forward-facing surface will be the surface which interacts with the airbag upon its deployment, determining a desired amount of gas within the airbag during inflation of the airbag based at least in part on the detected position of the occupant, and adjusting the amount of gas within the airbag during inflation of the airbag to provide the airbag with the desired amount of gas during its inflation. Adjustment of the amount of gas within the airbag may entail varying the amount of gas being directed into the airbag based on the morphology of the occupant (inflow control) and/or controlling the outflow of gas from the airbag based on the morphology of the occupant (outflow control).
