Patent number: 8648613Abstract: In method and a control device for triggering person protection device, a signal of a planarly measuring environment sensor system and a second signal of a contact sensor system are evaluated separately in order to produce a respective trigger signal. These two trigger signals are then gated in order to produce a third trigger signal. A trigger circuit triggers the person protection device as a function of this third trigger signal.Type: GrantFiled: July 7, 2008Date of Patent: February 11, 2014Assignee: Robert Bosch GmbHInventors: Frank Ewerhart, Reiner Marchthaler, Mario Kroeninger

Patent number: 7289018Abstract: A method for distance alert for a vehicle, the distance of the vehicle to obstacles in the vehicle's surroundings being detected. The output of an alert depends on whether or not an obstacle is located in the vehicle's travel path. If there is no obstacle located in the travel path, then an alert is only output at a substantially smaller distance than would be the case when an obstacle is located in the travel path. The method is used for avoiding unnecessary alerts about obstacles.Type: GrantFiled: January 27, 2005Date of Patent: October 30, 2007Assignee: Robert Bosch GmbHInventors: Frank Ewerhart, Clemens Guenther, Thomas Wittig, Arnd Engeln

Patent number: 6373378Abstract: An arrangement for visualizing the illumination by at least one vehicle headlight of a zone situated in front of the vehicle as considered in the forward driving direction includes a camera mounted on the vehicle and operative for taking a succession of scenes of the environment of the vehicle including the aforementioned zone as the vehicle travels on a roadway in the forward driving direction. A visualization device including a monitor visually renders the scenes obtained from the camera, and a simulated rendition of the region illuminated by the headlight is presented in the succession of scenes appearing on the monitor. The light beam issued by the headlight is presented in a simplification as a light cone.Type: GrantFiled: December 21, 1999Date of Patent: April 16, 2002Assignee: Robert Bosch GmbHInventors: Frank Ewerhart, Werner Poechmueller
