Patent number: 6759761Abstract: The device has a sensor device (20) and an evaluation device (30). The sensor device (20) has a global sensor (22), by which the general light intensity in the surroundings of the vehicle is detected nondirectionally, and a directional sensor (24), by which the light intensity is detected directionally in the travel direction of the vehicle. By the evaluation device (30), the signals (S1, S2) of the sensors (22, 24) of the sensor device (20) are compared with threshold values (SE), and if at least one threshold value (SE) is undershot, the lighting devices (10, 12) are switched on. A temperature measuring instrument (32) for detecting the temperature of the sensor device (20) is also provided, which supplies the evaluation device with a signal (ST) about the temperature. In the evaluation device (30), temperature-dependent basic signals (S10, S20) that the sensors (22, 24) generate without light incidence are stored in memory.Type: GrantFiled: February 6, 2002Date of Patent: July 6, 2004Assignee: Robert Bosch GmbHInventors: Patrick Schmitt, Norbert Hog, Bruno Hodapp, Rainer Pientka, Hans Meier, Henry Blizke, Manfred Burkart

Patent number: 6525478Abstract: A device for checking the evaluation circuit for automatic switching operations of the illumination devices in vehicles. A sensor device contains a global sensor for detecting the light conditions in the environment of the vehicle and a directional sensor for the directed detection of the light conditions in the direction of travel in front of the vehicle. The signals of the sensor device are supplied to the evaluation circuit, to determine whether a change in the switching state of the illumination devices is necessary. In order to check the evaluation circuit which is designed using analog technology, in the operating state, the voltage supply to the sensor unit is briefly interrupted at predetermined intervals, as a result of which the condition “night” is simulated. When the evaluation circuit is functioning correctly, this is detected by it as such.Type: GrantFiled: March 15, 2001Date of Patent: February 25, 2003Assignee: Robert Bosch GmbHInventors: Patrick Schmitt, Norbert Hog, Bruno Hodapp, Rainer Pientka, Hans Meier, Henry Blitzke, Manfred Burkart
