  • Patent number: 8392072
    Abstract: A system and method for detecting a rollover of a vehicle that includes at least one wheel reaction force sensing device for transmitting wheel reaction force signal indicative of an amount of force exerted on at least one wheel of the vehicle is provided. The system includes a controller operably coupled to the at least one wheel reaction force sensing device and including at least one accelerometer sensor for transmitting the acceleration signal. The controller is configured to determine a first force index in response to the wheel reaction force signal, determine a first lateral acceleration of the vehicle in response to the acceleration signal, compare the first force index to a threshold force index and the first lateral acceleration to a threshold lateral acceleration, and deploy a restraint system based on the comparison.

  • Patent number: 8219287
    Abstract: A system and method for performing side impact sensing in a vehicle including at least one side impact zone is provided. The system comprises a controller and at least one crash signature sensor. The controller is configured to deploy one or more safety restraints in response to at least one crash signature signal. The one crash signature sensor is positioned in the side impact zone. The crash signature sensor is configured to detect an impact with an object at the side impact zone. The crash signature sensor is further configured to generate the crash signature signal which corresponds to measured structural impact energy of the vehicle in the side impact zone deformed by the impact at frequencies above 2 kHz.

  • Patent number: 7162343
    Abstract: Intelligent vehicle rollover detection systems and methods are claimed and described. An embodiment may comprise various data sensors to sense various signals and a control circuit to receive the signals. In some embodiments, the control circuit may be adapted to provide a vehicle unstable signal to activate a first occupant restraint system and a rollover detection signal to activate a second occupant restraint system. In some embodiments, the control circuit may also determine an updated threshold and a reduced threshold, and generate a rollover detection signal in response to at least one of the updated threshold and a reduced threshold. Other embodiments are also claimed and described.

  • Patent number: 6856868
    Abstract: A rollover detection system (12) for an automotive vehicle (10) includes a controller (14) that is hooked to various types of sensors. The sensors may include a lateral acceleration sensor and another sensor or combination of sensors that gives an indication to another lateral condition of the vehicle. The controller determines a roll condition in response to comparing the lateral acceleration and the lateral condition other than lateral acceleration to a threshold. When the conditions are above the threshold then a roll condition is indicated. When a roll condition is indicated a safety device (40) may be controlled to prevent rollover and/or deploy a safety device.

    Abstract: A rollover sensing system (12) that may be used in the determination of when to deploy restraints in the vehicle. The rollover sensing system (12) may include lateral acceleration sensors (32), a roll rate sensor (18) and a roll angle detector (20). A control circuit (16) determines a predetermined rollover threshold in response to the roll rate and roll angle detector (20) and calculates an adjusted threshold as a function of the predetermined rollover threshold and the lateral acceleration. The control circuit (16) generates a control signal in response to the adjusted threshold.
