Abstract: A device is proposed for determining a relative speed between a vehicle and a crash object, the device being situated in the vehicle itself. The device has one active surround field sensor system and one contact sensor system. The device ascertains the relative speed with the aid of a first signal, the surround field sensor system and with the aid of a second signal of the contact sensor system.

Abstract: An apparatus for triggering personal protection means, having a surroundings sensor suite and a contact sensor suite, influences a pedestrian protection algorithm as a function of a first signal of the surroundings sensor suite, and influences a pre-crash algorithm as a function of a second signal of the pedestrian protection algorithm that takes into account a third signal of the contact sensor suite. The apparatus triggers the personal protection means as a function of a fourth signal of the pedestrian protection algorithm and a fifth signal of the pre-crash algorithm.

Abstract: A radar system for motor vehicles, having a radar sensor and an evaluation device for measuring distances and relative velocities of objects in the surrounding field of the vehicle, and a collision detection device, which, on the basis of the measured distances and relative velocities, recognizes an imminent collision and delivers data on the expected time of collision and the impact velocity to a precrash system. The radar sensor is switchable by the collision detection device to a velocity measurement mode in which a more precise measurement of the relative velocity is made.

Abstract: The invention relates to a method and a device for preventing rear end collisions with a vehicle. According to the invention, the distance (d) and/or speed (vrel) of the vehicle in relation to the vehicle in front are determined by means of an environmental sensor (2) oriented towards the front region of the vehicle. In the event of a stopping situation, a longitudinal dynamic value (alphaFP, alpha BP) initiated by the driver is evaluated in order to determine whether there is a risk of collision for the two vehicles in question. In the event of a risk of collision, the drive train (10) and/or the delay devices (11) of the vehicle are engaged in order to reduce the risk of collision and/or driver warning devices (12, 5) are triggered in order to inform the driver about the risk of collision.

Abstract: A safety system for occupants of a vehicle having, e.g., acceleration sensors and/or pressure sensors for sensing a side crash. The safety system also includes a detector to detect the lateral velocity of the vehicle. The control of the restraining devices of the safety system is able to be influenced by the detected lateral velocity.

Abstract: A device for classifying at least one object with the aid of an environmental sensor system.

Abstract: An apparatus for triggering a restraint apparatus, arrangement(s) or structure(s) in which, with a precrash sensor system, the apparatus generates a signal as a function of which the restraint apparatus, arrangement(s) or structure(s) is/are triggered. The precrash sensor system includes a combination of an ultrasound sensor system and a microwave sensor system. The ultrasound sensor system serves to detect objects at a speed of up to 40 km/h, while the microwave sensor system is used to detect objects up to a relative speed of 200 km/h.

Abstract: A device and a method for activating passenger protection means are described in which an acceleration sensor system which is sensitive in the vehicle longitudinal direction generates a first signal and a second acceleration sensor system which is sensitive in the vehicle transverse direction generates a second signal. Furthermore, an analyzer circuit is provided which activates the passenger protection means as a function of the first and second signals, the analyzer circuit (?C) determining at least one measure for vibrational energy occurring during a crash and deciding for activation as a function of this measure.
