An apparatus and method for controlling opening and closing of a vehicle door are provided. The apparatus includes a driving unit that opens and closes a door a controller that operates the driving unit. Additionally, an acoustic wave processing unit receives and analyzes an acoustic wave signal generated by force exerted onto the door to generate a control signal for opening or closing of the door. The controller receives the control signal to thus operate the driving unit. Further, the acoustic wave processing unit includes an acoustic wave sensor disposed inside of the door and receives the acoustic wave signal, and an MCU that analyzes a signal output from the acoustic wave sensor to generate the control signal.

An airbag device for a front passenger seat includes a front passenger seat airbag main body, a center airbag portion, an actuator and a control section. The actuator is configured to switch a strap between a first state and a second state. In the first state, the center airbag portion is retained in a folded state. In the second state, the other end portion of the strap is released and the center airbag portion is allowed to inflate and expand. The control section sets the actuator to the first state when there is a full overlap frontal collision, and sets the actuator to the second state when there is a collision that is any of an oblique collision against a driver seat side of a vehicle front portion or a small overlap collision.

A safety system for a motor vehicle includes a sensor suite detecting a lateral impact and a vehicle yaw, an occupant safety system, and a control module receiving signals from the sensor suite. The control module activates the occupant safety system if either: a) an impact magnitude detected by the sensor suite is greater than a first impact threshold and a vehicle yaw magnitude detected by the sensor suite is greater than a yaw threshold; or b) the impact magnitude is greater than a second impact threshold higher than the first impact threshold. The system may be operated to determine a longitudinal location of the impact on the vehicle by comparing a magnitude of the impact and a magnitude of the vehicle yaw. The occupant safety system may then be activated in a mode based upon the longitudinal location of the impact and/or appropriate for a spinning vehicle.

In a crash sensor and a method for processing a measured value of the crash sensor, at least one measured quantity is detected by a sensor element and a first rewritable memory is provided in which first data for influencing the processing of the at least one measured quantity are stored. In addition, a second hardwired memory is provided in which second data for influencing the processing are stored. A logic module is provided which loads the first or second data, as a function of a test of the first memory, for processing the at least one measured quantity.

A method for detecting a safety-critical impact of an object on a vehicle is described. The method has a first step of obtaining a starting signal for starting a time measurement, to establish the start of a subsequent predetermined time span. In addition, the method has a step of receiving a signal representing a yaw acceleration of the vehicle, the signal being received during the predetermined time span. Finally, the method has a step of detecting the safety-critical impact of the object on the vehicle detecting the safety-critical impact of an object on the vehicle when the signal within the predetermined time span has a value that is outside a threshold value range or when the signal after the predetermined time span has a value derived from the signal that is outside of a threshold value range.

A collision detecting method, an electronic device, and a computer program product thereof are provided for the electronic device having an accelerometer, a positioning module, and a communication module. The method includes obtaining a plurality of acceleration variations within each of a plurality of sampling intervals respectively detected by the accelerometer. The method also includes transforming the corresponding acceleration variations into a plurality of frequency domain signals for each sampling interval, and calculating energy and entropy of the frequency domain signals. The method further includes determining a collision has occurred if the energy and the entropy corresponding to each of a plurality of specific sampling intervals among the sampling intervals both drastically increase then drastically decrease suddenly.

A vehicle collision detector is configured to reliably activate an airbag system at a collision and prevent the airbag system from erroneously operating. The collision detector includes two acceleration sensors disposed at different positions in a vehicle to detect acceleration for collision determination, first and second collision routines in which a determination is made on whether or not a variation in the detected acceleration is caused by a collision, and a final collision routine in which an airbag module is activated when all of results of the first and second collision routines indicate a collision.

An adaptive energy absorption system for a vehicle seat is disclosed, utilizing an adaptive energy absorber or variable profile energy absorber (VPEA) for mitigating occupant injury due to extreme vehicle movement (e.g., during a vehicle shock event), and/or for mitigating vibration experienced by an occupant of the vehicle seat during normal vehicle operating conditions. The adaptive energy absorption system achieves the aforementioned objectives for a wide range of occupant weights and load levels. An alternate configuration of a dual-goal energy absorption system is also disclosed that enables both shock mitigation and vibration isolation.

A body structure of a vehicle reliably detects, with a side-collision detection sensor disposed on a pillar, a side-collision of a side door of a vehicle body against a pole and particularly a side-collision against a pole in a diagonal direction. A metal bracket that projects toward a vehicle width direction outer side is disposed on an outer side surface in a predetermined position (substantially intermediate position between a front pillar and a center pillar) of a rocker. By setting this metal bracket on the outer side of the rocker, in addition to an impact beam disposed inside a door, an acceleration (sensor G) transmitted to the side-collision detection sensor disposed inside the center pillar increases during a side-collision against a pole in a diagonal direction, so the side-collision state can be reliably and rapidly detected even at a position distant from the center pillar.
