A sensor arrangement, particularly for a passenger protection system of a motor vehicle, comprising a first group of sensors () by means of which a first group of state parameters jointly usable by a first decision making unit connected downstream for detecting a first event can be detected, a first digital unit () coupled on the input side to at least one sensor () of the first sensor group. The arrangement processes the sensor output signals fed thereto and providing the same for forwarding to the first decision making unit as digital values. A second group of sensors (), by means of which a second group of state parameters jointly useable by a second decision making unit is connected downstream for detecting a second event can be detected with a second digital unit coupled on the input side to at least one sensor () of the second sensor group. The arrangement processes the sensor output signals fed thereto and providing the same for forwarding to the second decision making unit as digital values wherein at least one sensor () of the first sensor group is coupled to the second digital unit () and at least one sensor () of the second sensor group is coupled to the second digital unit () and at least one sensor () of the second sensor group is coupled to the first digital unit (). The digital units () are coupled on their output sides to a first and a second node () combining the digital values.

An arrangement is provided for triggering a vehicle safety device. A proximity sensor () provides an output related to a distance to an object and/or the relative speed between the object and the sensor. A main accelerometer () is sensitive to acceleration in a predetermined direction. A supplementary accelerometer () is also provided. A first processing arrangement () performs an algorithm with the main algorithm, and is connected to receive an input from the proximity sensor and from the main accelerometer and to provide an output to a triggering signal generator (). There is a second processing arrangement () which receives a signal from the main accelerometer () and also from the supplementary accelerometer (). The second processing arrangement also provides an output connected to the said signal generator () to generate the triggering signal.

Arrangement for triggering a vehicle safety device

An arrangement for triggering a motor vehicle safety device. The arrangement incorporates a proximity sensor () which is configured to provide a proximity signal related to the distance to an object and/or the relative speed between the object and the sensor (). The arrangement also includes an accelerometer () and a first processing unit () which is configured to perform an arming algorithm on signals received from the proximity sensor () and the accelerometer (). A second processing unit () is provided to perform a crash algorithm on signals received from the proximity sensor () and the accelerometer (). The arrangement incorporates a logic gate () to generate a triggering signal () in response to simultaneous output of signals from the first processing unit () and the second processing unit ().

A pedestrian detection system is provided on a motor vehicle, in order to detect a pedestrian so that an appropriate safety device can be activated in order to provide protection to the pedestrian in the event of an impact with the pedestrian. The detection system has a first sensor arrangement () which is located at least 0.5 meters behind the front end of the motor vehicle. The first sensor arrangement () is configured to detect the speed of and/or distance to a part of an object (such as a pedestrian) located in front of the vehicle. That part of the object which is detected is part of the object which extends above a predetermined height, which is at least the height of the front edge of the hood or bonnet () of the motor vehicle.

Pedestrian detecting system

An electronic control circuit for a vehicle safety device includes an electrical activator responsive to a flow of current therethrough to activate the safety device. The electrical activator is present in a series connection including the activator and two switches. The series connection forms at least part of an electric circuit. The control circuit further includes a crash sensor producing an output signal when an accident is detected. A crash risk sensor produces an output signal when a certain crash risk is detected. One of the switches is closed in response to at least the output signal from the crash sensor. The other switch is closed in response to the output signals coming from both the crash sensor and from the crash risk sensor.
