Abstract: A sensor mount assembly including a housing, fastener and a lever mechanism. The housing contains a sensor having two electrical leads and includes an integral flange adapted to receive a fastener. The fastener includes a body and a head. The body is received in the flange to secure the housing to a mount. The lever mechanism is proximate the flange and includes a contact block and a conductor. The contact block is acted upon by the fastener head to move the lever mechanism and, hence the conductor, between a first position and a second position. The first position corresponds to an unmounted sensor and creates a short circuit condition between the two electrical leads. The second position corresponds to a properly mounted sensor and creates an open circuit between the two electrical leads such that the electrical circuit path of the overall system includes the sensor within the housing.

Abstract: An impact sensor is provided including a counter electrically coupled to the sensor and storing an impact sensor collision number. The impact collision number represents whether the impact sensor has been on a vehicle that has been involved in a collision. A method for indicating that the impact sensor has been on a vehicle that has been involved in a collision is also provided. The method includes sensing a collision and generating a collision signal in response to the collision. An impact sensor collision number is incremented and indicated in response to the collision signal.

Abstract: A restraints control module (RCM) for a vehicle is provided including a memory device. The memory device stores a deployment time of a deployment event. A controller is electrically coupled to the memory device and deploys a restraint in response to a collision signal and stores the deployment time in the memory device. A method of time stamping and indicating a deployment event within an automotive vehicle, having a RCM, is also provided.

Abstract: An occupant sensor system 12 is coupled to an airbag deployment system 14. Occupant sensor system 12 has an occupant sensor 24 that comprises a seat belt and a plurality of wires extending a predetermined length within seat belt 26. Wires 28 are coupled to a controller 22 that is used to sense a changing electrical characteristic of wires 28 such as capacitance or inductance to determine the presence of an occupant. Controller 22 in response to the signal from occupant sensor 24 may then adjust the deployment of an airbag 18.

Abstract: A communication system is provided for an automotive vehicle (10) that uses existing vehicle components with only slight modifications that can be implemented in readily changeable software. The present invention includes a vehicle bus (14) and a vehicle information source coupled to the vehicle bus. The vehicle information source (28) couples vehicle information to the vehicle bus (14). The transmitter (16) transmits a first communication having a first transmitter identification code and first vehicle information. A receiver (22) is coupled to the vehicle bus. The receiver (22) couples a second communication word having second vehicle information to the vehicle bus. The automotive vehicle (10) also has a safety system and a safety system controller (34) coupled to the bus. The safety system controller (34) actuates the safety system (36) in response to the second vehicle information.

Abstract: A secondary seat belt warning system for a motor vehicle includes at least one control module for activating at least one secondary warning signal. The secondary seat belt warning system also includes a driver seat belt sensor for producing an input signal indicative of a state of a driver seat belt between a buckled and unbuckled condition. The secondary seat belt warning system includes at least one passenger seat belt sensor for producing an input signal indicative of a state of at least one passenger seat belt between a buckled and unbuckled condition. The at least one control module communicates with the driver seat belt sensor and the at least one passenger seat belt sensor for activating the at least one secondary warning signal to alert a corresponding occupant of the motor vehicle if the state of at least one of the driver seat belt and the at least one passenger seat belt is the unbuckled condition.

Abstract: A method of deploying a passenger side airbag as a function of the actual mass of the occupant on the passenger seat. This is accomplished by providing force sensors at one or more of the anchor pieces at which a seat belt is connected to the vehicle. The sensors may be strain gauges that measure the deflection of bolts connecting the ends of the seat belt to the anchor pieces. By sizing the nominal resistance of strain gauges at two anchor pieces, the two resistors can be put in a series circuit such that only the sum of the two resistances need be measured. The measurements obtained are then used to obtain the vertical components of force due to the seat belt. This value is then be subtracted from the total vertical force measured by a seat cushion weight sensor to determine the mass of the seat occupant.

Abstract: An occupant detection sensor assembly for a motor vehicle includes a generally horizontal seat cushion portion and a generally upright back portion operatively connected to the seat cushion portion. The occupant detection sensor assembly includes a seat cushion disposed within the seat cushion portion of the seat having at least one channel therein. The occupant detection sensor assembly also includes at least one sensor connected to the seat cushion and communicating with the at least one channel. The occupant detection sensor assembly further includes an electronic controller electrically connected to the at least one sensor for detecting an occupant seated on the seat cushion portion.

Abstract: A restraint and fuel pump cutoff control system is disclosed wherein a restraint control module controls the restraint system such as an air bag deployment system and a fuel system power supply based upon data inputs from sensors positioned at various locations on the vehicle. When data received from the sensors indicates that a collision event has occurred and has reached the predetermined level of severity, power to the fuel system is cut off to prevent undesired pumping of fuel. If power is interrupted during a collision event, the fuel system will be cut off and remain cut off until reset by turning the ignition switch to off and then to run/start indicating a clean shutdown. The restraint control module utilizes collision data profiles to distinguish between power shutdowns occurring during a collision event and power shutdowns occurring when only background data is being received from the sensors.

Abstract: A method and apparatus for permitting a host automotive vehicle to avoid or mitigate the consequences of a collision between the host vehicle and a target automotive vehicle by using a combination of radar derived target information and transponder information. The host vehicle is equipped with a radar system operative detect the target vehicle and generate target data, and a computer which determines a likelihood of collision with target vehicle. If the likelihood of collision is above a certain level, the computer directs the radar system to transmit a directional interrogation system toward the target vehicle. The target vehicle is equipped with one or more transponders that receive the interrogation signal and respond by transmitting a response signal containing information indicating various dynamic and/or static characteristics of the target vehicle. The response signal is received by the host vehicle and is decoded to extract the target vehicle information.

Abstract: A system for monitoring the secured/unsecured status of seat belts in rear seating rows of a vehicle notes the number and/or location of seat belts secured at a base time when all doors are closed and the vehicle starts in motion. The vehicle operator is alerted to any later change in the number of secured belts by a visual display provided by a vehicle message center and/or an audible signal. When the vehicle slows to a stop and a door opens, the number of secured belts is reset to allow continued monitoring of rear seat occupants after occupants are dropped off and/or picked up. The secured/unsecured condition may be determined by monitoring a retractor reel of the seat belt, the secured condition being defined by the seat belt being paid out beyond a threshold length and the unsecured condition being defined by the seat belt being retracted shorter than the threshold length.
