摘要:
The invention relates to a triggering control device for occupant restraint systems in a vehicle whose triggering readiness can be influenced as a function of collision-relevant parameters. According to the invention, collision parameter detection comprises object detection, which can detect a collision object before a collision occurs in an area near the vehicle, and can determine at least a relative speed. Whenever a collision object is detected, a signal generator delivers a collision parameter signal that depends on the relative speed determined. In a preferred embodiment the collision parameter detection unit also determines the intrinsic speed of the vehicle and whenever no collision object is detected, the signal generator supplies a collision parameter signal influenced by the intrinsic speed.

A method and system for restraining an occupant on a vehicle seat, the occupant being pulled into the vehicle seat is provided with a force by a belt tensioner when a critical driving state is detected and then held in a pulled-back position on the vehicle seat with a holding force. The holding force selected is lower than the force for pulling the occupant back. A forward-looking detection system for a dangerous driving state and an occupant-position detection system unprovided, in which, when a dangerous driving state is detected, a belt tensioner is subjected to a force and the occupant is thereby pulled into the vehicle seat, and in which the occupant is held in a pulled-back position on the vehicle seat with a holding force which is lower than the force for pulling the occupant back.

A vehicle impact detection sensor for providing an input variable for an activation logic unit or for generating an activation signal for an active occupant protection system, has a radar transmitter and a radar receiver which are arranged on a sensor-carrying superstructure of the vehicle. The radar receiver receives radar waves which are emitted by the radar transmitter and reflected at an impact-relevant reflexion surface that moves relative to the sensor-carrying superstructure in the event of an impact. A Doppler frequency evaluation unit uses the frequency of the transmitted radar waves and the frequency of the radar waves reflected from the impact-relevant reflexion surface to determine the associated Doppler frequency and detects therefrom a relative movement of the impact-relevant reflexion surface with reference to the sensor-carrying vehicle superstructure. The impact-relevant reflexion surface is a surface permanently connected to the vehicle, preferably, an outer surface of the vehicle.

A belt tightener of a seat belt in a vehicle, in particular a motor vehicle, is provided with a retracting spring in order to return the belt. A counterspring, which can be adjusted by a motor, is connected in parallel with the retracting spring in order to be able to reduce the tensile force of the belt for comfort considerations. The motor can also be connected in drive terms to the belt via a coupling arrangement to give reversible belt tightening.

Method for actuating a reversible belt pretensioner for pretensioning a belt webbing, the belt pretensioner having a drive which acts on the belt reel, and the seat belt having, as a belt extraction lock, a locking device which acts on the belt reel in the unwinding direction and whose locking can be released only if the belt reel is rotated through a specific angle of rotation in the winding-on direction. After the triggering of the belt pretensioner, the drive of the belt pretensioner for opening the locking device is actuated in an opening mode such that firstly, in a winding-on phase, the belt reel rotates through the specific angle of rotation in the winding-on direction. In a subsequent holding phase, the drive of the belt pretensioner is actuated for a predefinable holding time TH such that the belt reel is held in its angular position.

Method for actuating a reversible belt pretensioner for pretensioning a belt webbing, unwound from a belt reel, of a seat belt in a motor vehicle, the belt pretensioner having a drive which acts on the belt reel, and the seat belt having, as a belt extraction lock, a locking device which acts on the belt reel in the unwinding direction and whose locking can be released only if the belt reel is rotated about a certain angle of rotation in the winding-on direction. After a triggering of the belt pretensioner caused by a hazardous situation and if a variable indicative of the belt force indicates a decrease in the belt force, an opening mode is initiated in which the belt pretensioner drive is actuated in order to open the blocking device in such a manner that, at the beginning of the opening mode, the belt reel rotates about the specific angle of rotation in the winding-on direction.

In a brake control system for mitigating the consequences of an accident in the case of a rear-on collision of a motor vehicle, it is provided that a comparison signal assigned to the positive longitudinal acceleration of the vehicle is determined, that the comparison signal is compared with a threshold value and that, in the event that the comparison signal exceeds the threshold value, a braking signal triggering the vehicle brake is generated.
摘要:
A method for controlling a restraint device for occupants of a vehicle is provided. An environment of the vehicle is captured and a restraint device is triggered depending on object data and vehicle data determined in the environment. An impact probability is determined in stages based on determined object data and/or vehicle data. Depending on the determined strength of impact probability of a respective stage, a restraint device is pre-triggered or triggered, or triggering of restraint device is suppressed and determined triggering information is processed further in a next stage.
