摘要： A side impact sensor processes side acceleration signals and upon a crash event develops a deploy signal which comprises accurately timed pulses of preset duration including a single pulse wake up message and a multiple pulse deploy message. A single wire interface couples the deploy signal to a microprocessor in a central controller which manages deployment of side and frontal air bags and runs frontal impact algorithm. The pulse edges cause interrupts used to measure the pulse widths which are compared to stored values to verify the messages. A wake up pulse causes the microprocessor to give priority to an algorithm for processing the deploy message over the frontal algorithm and still service the frontal algorithm without degradation. Signal drivers in the side impact sensor impose sharp pulse edges for the deploy signal and sloping edges for other signals monitoring the state of health of the side sensor to reduce radiated emissions.

摘要： An improved vehicle seat occupant weight estimation method detects weight applied to both the seat cushion and the floor forward of the seat, and increases the measured seat weight of the occupant to account for occupant weight off-loaded to the floor. Fluid-filled bladders or other sensors are arranged to detect occupant seat weight and the weight applied to the vehicle floor forward of the seat. Upon opening of a vehicle door or an off-to-on transition of the vehicle ignition switch, the seat and floor weight sensors are monitored to detect the presence of an occupant. When the seat becomes occupied, or whenever there is a large change in the measured seat weight, the seat and floor weight are recorded, the occupant weight is estimated according to the recorded seat weight, and the inflatable restraints are allowed or suppressed based on the estimated occupant weight. When a sustained occupant weight shift is detected, the estimated occupant weight is increased in proportion to the amount of weight shifting, but is limited to a maximum value based on the detected floor and seat weights.

摘要： An improved occupant weight detection system measures the pressure in a fluid-filled bladder disposed in or under a foam seat cushion as an indication of occupant weight, and periodically adjusts the pressure vs. occupant weight relationship to compensate for changes due to aging and usage of the foam seat cushion. The system controller develops an aging adjustment value based on a measure of the cumulative aging and usage of the seat, and uses the developed adjustment value to compensate the operation of the system. The aging adjustment value is determined primarily as a function of occupant weight and time of seat occupancy, and the compensation is achieved by using the aging adjustment value to adjust either the estimated weight, or a threshold to which the measured pressure is compared for purposes of deciding if restraint deployment should be enabled.

摘要： A low-cost automatic suppression apparatus allows or suppresses deployment of a low risk deployment airbag based solely on occupant seat load and seat belt tension. The seat load and belt tension parameters are detected by low-cost sensors, and an airbag control unit suppresses airbag deployment when the occupant load is below a specified load threshold or the belt tension is above a specified tension threshold, and otherwise allows airbag deployment. The sensors are preferably switch-based so that the signals provided to the airbag control unit are in the form of a differential electrical current, and only two wires are needed to interface each sensor to the airbag control unit.

摘要： An occupant weight-based airbag suppression method utilizes adjustable time constant filtering and dynamic threshold adjustment to reliably determine and indicate airbag suppression status. The filter time constant is ordinarily set to a first value that provides relatively fast tracking of the raw occupant weight, but is set to a second value that provides relatively slow tracking of the raw occupant weight when both the raw and filtered occupant weights are within a specified band about the threshold value. The threshold value and band are dynamically adjusted after the suppression status is initially determined so as to effectively increase the separation between the filtered weight and the threshold.

摘要： A multiple sensor, vehicle seat occupant status determination system uses dynamic variations in occupant responsive sensor output due to accelerations of the vehicle seat to discriminate via a statistical method between sensors that are failed and those that are operating correctly and eliminates the contribution of signals detected as not valid from the status determination. If and only if the maximum and minimum sampled signal values of at least one of the received signals span upper and lower control reference values derived from the sampled signal values, a variance value for each of the signals is derived; and one or both of the greatest two or the smallest two variance values are checked against a relative size factor to detect an outlier signal value. If an outlier signal value is detected more than a predetermined number of consecutive times, the status classification is performed without signal values from the outlier sensor.
