A device for determining the instant a vehicle makes contact with an impact object. The device determines the instant of contact by approximating a signal derived from an acceleration signal using a function.

Device for determining the instant a vehicle makes contact with an impact object

A control device and a method for triggering passenger protection means for a vehicle are provided, the passenger protection means being triggered as a function of at least one signal from an impact sensor system and at least one precrash signal. The at least one precrash signal is evaluated as a function of a classification of at least one functionality, the functionality being influenced as a function of the least one precrash signal.

Method and control device for triggering passenger protection means for a vehicle

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.

Device for determining a relative speed between a vehicle and an impact object

A method for activating a restraint system in a vehicle, in which the restraint system is activated as a function of a speed, an activation characteristic, and at least one quantity derived from an acceleration signal, and in which the at least one quantity exceeds a threshold function that is set as a function of the impact speed and a required activation time. The activation characteristic of a particular accident type runs linearly to a first impact speed value. The activation characteristic runs with a second slope between the first impact speed and a second impact speed value, the first and the second impact speed value depending on the particular vehicle type.

Method for activating a restraint system in a vehicle

A safety device for vehicles having first sensor arrangement for acquiring the vehicle impact and for outputting first sensor signals, a control device for outputting triggering signals dependent on the first sensor signals, and a restraint system that is triggered dependent on the first sensor signals, second sensor arrangement being provided for the acquisition of obstacles in the vicinity of the vehicle and for the outputting of second sensor signals, and third sensor arrangement being provided for the acquisition of environmental influences on the second sensor arrangement, the second sensor signals output by the second sensor arrangement being used in the control unit for the decision concerning the triggering of the restraint system, after an evaluation of the third sensor signals output by the third sensor arrangement.

Restraint system with impact recognition, taking into account environmental influences

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.

Apparatus for triggering personal protection means

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.

Radar system for motor vehicles

A device for activating an actuator system for protecting a pedestrian is provided, the device being connected to an environment sensor system and a contact sensor system. The device compares a first signal from the contact sensor system to a threshold. The threshold or the first signal is changed as a function of a second signal of the environment sensor system and the actuator system is activated as a function of the comparison.

A method for triggering an occupant protection device in a vehicle including the steps: detecting a first measured variable and simultaneously generating a corresponding first signal for indicating a necessity for triggering at least one occupant protection device; detecting an acceleration value in the z direction and simultaneously generating a corresponding second signal; calculating a trigger signal for triggering at least one occupant protection device as a function of the first and second signals, and triggering the at least one occupant protection device as a function of the calculated trigger signal. An appropriate device is also described.

Method and device for controlling an occupant protection device in a vehicle

A device for classifying at least one object with the aid of an environmental sensor system. The device classifies the at least one object on the basis of its velocity and acceleration, the device determining the velocity and the acceleration from a signal of the environmental sensor system.

Device for classifying at least one object with the aid of an environmental sensor system

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.

Apparatus for triggering restraint means

A device for recognizing a pole crash, situated in a vehicle. The pole crash is determined on the basis of an impact velocity, which is recognized by an environment sensor, and an acceleration, which occurs in upon impact and is recognized by an impact sensor. In particular, the time between the impact and the impact object hitting the engine block is determined to identify a pole crash.

Device for recognition of a pole crash

A device, for controlling a vehicle-occupant restraining device in a vehicle having a trailer, includes an arrangement for controlling the vehicle-occupant restraining device as a function of at least one signal of the trailer.

Device for triggering restraint means

An apparatus for protecting a vehicle occupant that triggers a restraint means as a function of the vehicle occupant's motion in the context of an accident. The motion is predicted in that by using an occupant detection system and an impact sensor system, a height of the center of mass of the vehicle occupant and a force action on the vehicle occupant are determined, and the motion of the vehicle occupant is thereby predicted.
