A control system and corresponding control method which is adapted and intended for use in an own vehicle for detecting one or more objects based on environmental data obtained from one or more environmental sensors disposed at the vehicle. The environmental sensors are adapted to provide an electronic control unit of the control system with the environmental data which reflect the areas in front of, laterally next to and/or behind the vehicle. The control system is at least adapted and intended for detecting at least one object by means of the environmental sensors during a predetermined period of time or continuously. A movement of each detected object is determined. The presence of a rotational part in the movement of at least one object is identified, and when a rotational part is present, a probability of an occurrence of a collision between the corresponding object and the own vehicle is calculated.

Control system and control method for determining a probability of an imminent collision of a vehicle

A method for controlling an active restraint system in a motor vehicle includes providing of several status signals, transferring of the status signals to a control algorithm as input values, and controlling the active restraint system according to the result of the control algorithm. The method is characterized by checking whether one or more of the status signals have failed, reproducing a failed status signal, and replacing the failed status signal by its reproduction.

Method for controlling an active restraint system

An actuating device for a safety arrangement in a vehicle has a pneumatic muscle as a drive and a pyrotechnical gas generator for feeding the pneumatic muscle.

Actuating device for a safety means

A method for vehicle-sensitive actuation of a locking mechanism for a seatbelt retractor in a vehicle by means of a actuation signal that is generated by a control unit equipped with a microcontroller. Measured signals are transmitted to the control unit from several sensors that detect the vehicle situation. The actuation signal is suppressed when a suppression algorithm in the control unit determines that the seatbelt is not in use, that the vehicle is standing still, that the vehicle speed is not above a certain limit value, or that only the vehicle acceleration measured in the vertical direction exceeds a certain triggering limit value.

Vehicle-sensitive actuation of a seatbelt retractor

An actuating device for a safety arrangement in a vehicle has a pneumatic muscle as drive and a pyrotechnical gas generator for feeding the pneumatic muscle.

The belt retractor of the occupant restraint system comprises a frame, a belt reel rotatably mounted in the frame, a locking mechanism for selectively blocking the belt reel and a vehicle-sensitive sensor. The locking mechanism is actuated by an actor. An electronic control unit is provided with an input interface and an output interface. The vehicle-sensitive sensor is connected to the input interface and the actor is connected to the output interface.
