  • Patent number: 11912306
    Abstract: A method helps to protect an occupant of a vehicle (10) equipped with an automated driving system (200) and a vehicle safety system (100) by detecting low impact crash events (99) with the vehicle (10). The method includes utilizing automated driving sensors (220, 230, 240, 250, 260) of the automated driving system (200) to identify possible low impact collision risks. The method also includes utilizing vehicle safety system sensors (110, 115, 120, 125, 130) of the vehicle safety system to determine a low impact collision resulting from the identified possible low impact collision. A vehicle safety system (100) includes an airbag controller unit (150) configured to implement the method to determine low impact crash events with the vehicle (10).

  • Publication number: 20230116504
    Abstract: A method for controlling actuation of an actuatable restraint in response to a vehicle rollover event includes detecting whether the vehicle (12) is being driven off-road. The method also includes determining whether the vehicle (12) is undergoing a roll event (99) that would warrant actuation of the actuatable restraint (20) if the vehicle was being driven on-road. The method further includes actuating the actuatable restraint (20) in response to determining that a roll acceleration (D RATE) of the vehicle (20) indicates that the roll event is continuing. A vehicle safety system (10) includes an actuatable restraint and a controller (50) configured to control actuation of the actuatable restraint according to this method.

  • Patent number: 11560108
    Abstract: A vehicle safety system implements a method for helping to protect a vehicle occupant in the event of a frontal collision. The method includes determining a passive safety crash mode classification in response to crash signals received in response to the occurrence of a crash event. The method also includes determining an active safety crash mode classification in response to active safety signals received prior to the occurrence of the crash event. The method also includes determining an active safety confidence factor for the active safety crash mode classification. The method also includes determining the weighted crash mode classification as being the active crash mode classification in response to the active safety confidence factor exceeding a predetermined confidence value. The method further includes determining the weighted crash mode classification as being the passive crash mode classification in response to the active safety confidence factor not exceeding the predetermined confidence value.

  • Patent number: 11554734
    Abstract: A vehicle safety system includes an actuatable restraint for helping to protect a vehicle occupant and a controller for controlling actuation of the actuatable restraint in response to a vehicle rollover event. The controller is configured to execute a discrimination algorithm comprising at least one classification metric that utilizes at least one of vehicle pitch rate (P_RATE) and vehicle roll acceleration (D_RATE) to discriminate at least one of a ramp rollover event and a soil rollover event from an embankment rollover event. The discrimination algorithm determines a classification of the vehicle rollover event as one of a ramp rollover event, a soil rollover event, and an embankment rollover event. The controller is also configured to select a deployment threshold for deploying the actuatable restraint. The deployment threshold corresponds to the classification of the vehicle rollover event.

  • Patent number: 11505149
    Abstract: A method for controlling the actuation of an actuatable restraint to help protect a vehicle occupant in response to a rollover event is implemented in a controller of a vehicle safety system that includes the actuatable restraint. To implement the method, the controller is configured to execute a roll discrimination metric that discriminates the occurrence of a ramp rollover event or an embankment rollover event in response to a vehicle roll rate (R_RATE) having a magnitude that exceeds a predetermined threshold roll rate (R_RATE). The controller is also configured to execute a switching metric that is operative to reduce the predetermined threshold roll rate (R_RATE) in response to a vehicle pitch rate (P_RATE) having a magnitude that exceeds a predetermined threshold pitch rate (P_RATE).

  • Publication number: 20210031714
    Abstract: A method for controlling an actuatable safety device for helping to protect a vehicle occupant includes sensing a plurality of vehicle acceleration parameters. The method also includes executing one or more metrics that evaluate the acceleration parameters to determine whether vehicle crash thresholds are exceeded and producing crash event indications in response thereto. The method also includes evaluating the crash event indications to identify a pole side impact, and controlling deployment of the actuatable safety device in response to identifying the pole side impact crash event. In one particular configuration, identifying the pole side impact crash event includes discriminating the pole side impact crash event from a barrier side impact crash event.

  • Patent number: 9481335
    Abstract: An apparatus (50) detects a pedestrian/vehicle impact, the apparatus including a plurality of sensors (62, 64, 66) mounted near a forward location of a vehicle (52), each sensor providing an associated signal indicative of an impact event. A metric determining device (80) determines metric values for each of the sensor signals. A controller (80) determines if any of said determined metric values indicates the occurrence of a misuse event. The controller also determines if a pedestrian/vehicle impact event is occurring by comparing the metric value of at least one sensor signal against a selectable threshold. An actuation signal is provided in response to the comparison. The selectable threshold is selected in response to the determined occurrence of a misuse event. An actuatable pedestrian impact mitigation device (84) is attached to the vehicle and is actuated in responsive to the actuation signal from said controller.
