A method for a vehicle, in particular a vehicle which is operated in an at least partially automated manner, for detecting an impact event. The method includes of:

Detection of an impact event

A method for activating an emergency braking function of a vehicle. At least one restraint unit is activated in the process for restraining at least one occupant of the vehicle in response to an identification of an imminent triggering of the emergency braking function, using at least one sensor signal of at least one sensor of the vehicle. The triggering of the emergency braking function takes place when the restraint unit is activated.

Method and control unit for activating an emergency braking function of a vehicle

A method for detecting damage to motor vehicles. The method includes: acquiring at least one external microphone signal that was ascertained using at least one external microphone, acquiring at least one internal microphone signal that was ascertained using at least one internal microphone, comparing the at least one external microphone signal and the at least one internal microphone signal, and ascertaining a compare function, which represents a deviation between the external microphone signal and the internal microphone signal, and ascertaining a damage classification for classifying the damage to the motor vehicle based on the compare function.

Method and device for detecting damage to a motor vehicle

A pre-crash system has at least one dummy actuator and an adaptive pre-trigger function that is implemented with different parameter sets as a function of a current degree of validation, and evaluates the acquired physical quantities for pre-crash recognition in order to recognize an unavoidable crash, a first parameter set, which limits the pre-trigger function to a dummy operating mode in which the pre-trigger function produces at least one trigger signal for the dummy actuator if the evaluation of the physical quantities permits the inference of an unavoidable crash, being implemented until the current degree of validation satisfies a specified condition, the pre-trigger function comparing the triggering of the dummy actuator with the behavior of the evaluation and control unit, and, as a function of the comparison, rating the triggering of the dummy actuator as 'correct' or as a 'false positive.'

Safety system for a vehicle of a vehicle fleet

A method for warning of the wrong-way travel of a vehicle after an accident and/or a safety-critical driving situation, especially after an interim standstill of the vehicle, the method including a detecting task, in which a change in a direction of travel of the vehicle after an accident is detected. Finally, the method includes a task of providing a warning signal, the warning signal being provided as a function of a detected change in the direction of travel of the vehicle, to output the warning of the wrong-way travel of the vehicle after the accident and/or the safety-critical driving situation.

Method and apparatus for warning of the wrong-way travel of a vehicle after an accident and/or a safety-critical driving situation, especially after an interim standstill of the vehicle

A method for protecting and restraining a passenger on a passenger seat of a vehicle in case of an accident, with the aid of at least one restraint element of a protection and restraint device, an evaluation and control unit for a protection and restraint device for carrying out the method, a protection and restraint device for protecting a passenger having such an evaluation and control unit, as well as a corresponding computer program and computer program product for carrying out the method are described. A positioning applied force is generated as a function of an ascertained current driving situation, the applied force accelerating the passenger away from a vehicle side structure in the direction of the middle of the vehicle if a predefined precrash situation is detected.

Method and device for protecting and restraining a passenger and an evaluation and control unit for a protection and restraint device

A method for operating a motor vehicle from a plurality of motor vehicles includes the steps of determining, by a central point, that a systematic malfunction is present in a plurality of motor vehicles; providing a communication link between the central point and the motor vehicle; and putting at least one electronic control unit of the motor vehicle into a safe operating mode to ensure the operational safety of the motor vehicle.

Safe operation of a motor vehicle

A method for activating personal protection means using at least one signal derived from an acceleration sensor. A forward displacement is determined from the signal, and the forward displacement is compared to at least one threshold value surface, which is set as a function of a velocity decrease and a deceleration. The personal protection means is activated as a function of the comparison.

Method for activating personal protection means

A method is described for generating at least one feature for an occupant protection system, which is determined from at least one basic feature and analyzed for generating a triggering signal for an occupant protection device, and a corresponding device. During normal operation, at least one short-term window integral is calculated from the at least one basic feature and used as a starting value for calculating a corresponding long-term integral when a starting condition for a crash operation obtains, the at least one long-term integral being made available to a following method as a feature for generating the triggering signal for the occupant protection system.

Method and device for generating at least one feature for an occupant protection system

A method for triggering restraint devices in which at least one collision-indicating signal is generated. From the moment that a collision is detected, temporally defined crash phases are specified, and, for every crash phase, a crash type and a crash severity are determined from the signal. The appropriate restraint devices are triggered as a function of the crash severity and/or the crash type.

Method for activating restraining means

An apparatus for detecting impact of a moving object, in particular of a vehicle, having a first sensor device for acquiring an acceleration in a direction of motion of the moving object, an evaluation device for evaluating the first acceleration signal, and at least one second sensor device for acquiring an acceleration in an acquisition direction that is different from the direction of motion of the moving object, a classification of an impact by way of a classification signal being made available as a function of accelerations in at least two directions of motion or three acceleration directions.

Method for recognising a collision by means of an upfront sensor system and device for carrying out said method

A method for triggering a restraining device in a motor vehicle is proposed, where a crash severity and an occupant categorization are implemented independently of each other. By linking the crash severity with the occupant categorization, the restraining device required for the vehicle occupants is triggered. The crash severity is subdivided in accordance with the triggering events frontal impact, side impact, rear impact or vehicle roll-over. A decisive advantage is that the crash severity is implemented independently of the occupant categorization.

Method for triggering restraining means in a motor vehicle

A method of classifying an obstacle on the basis of pre-crash sensor signals is described, acceleration and acceleration change being determined from the obstacle velocity, and the obstacle is classified on the basis of these parameters. The deployment algorithm is tightened as a function of this classification; if appropriate, restraining means are deployed at an early stage and an automatic braking and/or steering intervention takes place.

Method for classifying an obstacle by means of pre-crash sensor signals

A system for sensing a head-on collision in a vehicle, where at least one upfront sensor is used as plausibility sensor, which provides a plausibility signal for a collision sensor located in the control device. The upfront sensor may be an acceleration sensor, which analyzes both the acceleration signal as well as the speed signal derived therefrom for a plausibility check. The results of this check are linked in an OR-operation in order to generate a plausibility signal. In an example embodiment, it is provided to buffer-store the plausibility signal in the control device for a predetermined time. This is of special interest for improved reliability in the event that the upfront sensor has been destroyed.

System for sensing a head-on collision in a motor vehicle

A restraint system having a restraint device for protecting at least one passenger and a method for controlling a restraint system. The system and method act so as to to transform using a wavelet transformation, a signal measured by an acceleration sensor into a frequency range and in order to determine from the transformed signal the optimal triggering time point for the restraint device. For this purpose, the wavelet-transformed signal, on the one hand, is used for determining features in order to determine a crash type, and, on the other hand, to determine the braking acceleration energy. If the braking acceleration energy lies above a preestablished threshold value and if the identified crash type requires a triggering of the restraint system, then the restraint system is triggered.
