According to one aspect, a vehicle safety system includes an actuatable controlled restraint (ACR) comprising a seatbelt for restraining a vehicle occupant. The ACR is actuatable to control payout and retraction of the seatbelt. The system also includes a controller configured to determine operating conditions of the vehicle and to control the actuation of the ACR in response to the determined operating conditions of the vehicle. The ACR has a normal restraint condition and an enhanced restraint condition, the controller being configured to actuate the ACR from the normal restraint condition to the enhanced restraint condition in response to determining abnormal driving conditions of the vehicle.

A method for controlling at least one assistance function in the event of a rollover of a vehicle. The vehicle includes at least one acceleration sensor with zero point feedback. The method includes reading in a sensor signal and ascertain or reading a feedback signal. The sensor signal represents acceleration values detected by the at least one acceleration sensor. The feedback signal represents control values for the zero point feedback of the at least one acceleration sensor. The method also includes determining an occurrence of a rollover as a function of a result of comparisons. Furthermore, the method includes providing a rollover signal for output to the at least one assistance function. The rollover signal represents a recognized rollover of the vehicle.

An apparatus for determining a rollover condition of a vehicle may include: a rate sensing unit configured to sense one or more rates of a pitch rate PitchRate and a yaw rate YawRate of a vehicle and a roll rate RollRate_IN; an acceleration sensing unit configured to sense horizontal acceleration and vertical acceleration of the vehicle; a conversion unit configured to convert the horizontal acceleration and vertical acceleration into a pitch rate PitchRate_ACC and a yaw rate YawRate_ACC; a combination unit configured to calculate a pitch rate PitchRate_IN and a yaw rate YawRate_IN by combining the one or more rates with the pitch rate PitchRate_ACC and the yaw rate YawRate_ACC; and a determination unit configured to calculate a roll angle RollAngle, and determine whether the vehicle has rolled over, based on the roll rate RollRate_IN and the roll angle RollAngle.

A method for generating a signal representing an impact intensity including the steps: receiving at least three signals, which represent respectively accelerations in different spatial directions; calculating a direction-independent variable from the three signals; ascertaining an integrated measurand of the direction-independent variable over a time window; generating a signal representing an impact intensity on the basis of the ascertained integrated measurand.

A vehicle includes an acceleration sensor detecting collision, an electric actuator disposed outside a vehicle body, a battery and a boosting circuit supplying a high voltage to the electric actuator, and an electric suspension control ECU controlling the boosting circuit and the electric actuator, and in a case where the acceleration sensor detects the collision, the electric suspension control ECU limits the supply of the high voltage to the electric actuator.

A control device for controlling a passenger protection device for a vehicle includes an input unit configured to receive a first acceleration signal in a first axial direction and a second acceleration signal in a second axial direction which are generated by an acceleration sensor disposed in a side door of a vehicle, a determination unit configured to determine whether a collision has occurred in the side door of the vehicle using at least one of the first acceleration signal and the second acceleration signal, and a control unit configured to control a passenger protection device disposed adjacent to the side door of the vehicle based on a result of determining whether the collision has occurred.

A system for detecting accidents; the system may include a sensor configured to detect a motion of the automobile from a resting state. The system also includes a plurality of cameras configured to capture an image a predetermined proximity from a vehicle. The plurality of cameras are actuated through wireless communication with the sensor. A controller is in wireless communication with the sensor and the plurality of cameras and configured to receive and store an image from the plurality of cameras. The system may be designed to take a recording of all parties involved in an automobile collision.

A method for generating a signal representing an impact intensity including the steps: receiving at least three signals, which represent respectively accelerations in different spatial directions; calculating a direction-independent variable from the three signals; ascertaining an integrated measurand of the direction-independent variable over a time window; generating a signal representing an impact intensity on the basis of the ascertained integrated measurand.

An occupant safety system for a vehicle seat is disclosed. The motor vehicle seat has a seat face, a backrest that is adjacent to the seat face and a headrest that is arranged at an upper side of the backrest. At least one airbag is arranged in the headrest. The at least one airbag is constructed in such a manner that, in an inflated state, the at least one airbag prevents an occupant without any belt system from contacting a vehicle roof by acting on shoulders of an occupant in the seat.

A collision preventing ECU 10 determines that a support performing condition is established when a relationship between a threshold and a collision index value representing emergency degree of a collision between an object and the own vehicle satisfies with a predetermined relationship. In this case, the ECU performs a collision preventing control for preventing the collision. The ECU determines whether or not the object is a continuous structure. The ECU determines whether or not a running status is a steering operation running status. The ECU changes at least one of the collision index value and the threshold such that the support performing condition becomes more difficult to be established when a specific condition that the object is determined to be the continuous structure and the running status is determined to be the steering operation running status is established than when the specific condition is not established.
