Patent number: 8494724Abstract: A sensor system and method for detecting particles, in particular dirt particles or water droplets on a vehicle windscreen, comprising an optical sensor (3). The sensor (3) operates on the basis of light transit time and receives light signals (S) that are emitted by an emitter element and that are at least partially reflected, wherein the emitter element and the sensor (3) are located and aligned on the exterior of the vehicle, on or in the vicinity of a tailgate, hatchback or trunk lid (2) of said vehicle (1) in such a way that particles on the tailgate, hatchback or trunk lid (2) can be detected by means of the sensor (3) by sensing the part of light signals (S) emitted by the emitter element that is backscattered by the particles.Type: GrantFiled: September 23, 2008Date of Patent: July 23, 2013Assignee: Daimler AGInventors: Juergen Luka, Axel Mueller

Publication number: 20090234514Abstract: A system for controlling a plurality of components in a means of transportation includes a control device with a first control program for a first component and additional control programs for additional components. Each control program carries out a chronologically limited process to control the assigned component. Processes are executed for the components which can be actuated in parallel on the same control device. To each of the processes is assigned a priority identifier that is compared with that of other processes to determine if the process is input into a waiting memory, and to determine the process with the highest priority to start controlling the corresponding component. The priority identifier is allocated dynamically depending on different conditions of the means of transportation.Type: ApplicationFiled: February 22, 2006Publication date: September 17, 2009Applicant: DiamlerChrysler AGInventors: Juergen Becker, Joachim Eisenmann, Sibylle Cornelia Eisenmann, Markus Fabian Eisenmann, Tobias Eisenmann, Michael Huebner, Juergen Luka

Patent number: 7581521Abstract: A driving authorization system comprises an electronic immobilizer function which is coupled to a rotary shaft sensor. The rotary shaft sensor senses the position and/or rotational speed of the rotary shaft by means of a pickup wheel arranged on a rotary shaft, and transmits that information to a vehicle control unit which enables the electronic immobilizer function. According to the invention, the pickup wheel comprises a predefined number of teeth which are arranged distributed along the circumference of the pickup wheel according to a code, and an encoded rotational speed signal which is picked up by the rotary shaft sensor and can be decoded by the vehicle control unit. The vehicle control unit enables the immobilizer function only after successful decoding of the encoded rotational speed signal. A synchronization time for detecting a specific position of the rotary shaft is part of the encoded rotational speed signal.Type: GrantFiled: July 28, 2006Date of Patent: September 1, 2009Assignee: Daimler AGInventors: Staas Gietzen, Thomas Hartmann, Juergen Luka, Sylvain Subileau, Hermann Von Hasseln

Publication number: 20090013170Abstract: A control device for controlling components in a vehicle with an interface to an external databus is described. The device includes a hardware module and a memory for making available the data necessary for the data processing. Controller processes are executed by control processes which can be actuated chronologically in parallel with one another, as a result communicating directly via an interface to the databus or with sensors/actuators in order to control components of vehicle. The control device has at least two configurable hardware modules which carry out a plurality of control processes in parallel on the basis of the messages from the databus or on the basis of the control instructions of the control device. A distribution unit is provided for assigning the controller processes which run in parallel to the hardware modules.Type: ApplicationFiled: February 22, 2006Publication date: January 8, 2009Applicant: DAIMLERCHRYSLER AGInventors: Juergen Becker, Joachim Eisenmann, Sibylle Cornelia Eisenmann, Markus Fabian Eisenmann, Tobias Eisenmann, Michael Huebner, Juergen Luka

Publication number: 20050154475Abstract: A control device for controlling a system having a processor for executing control programs, memory means for storing data and control programs, and interface modules which can be used to transfer control instructions to actuators or to further control devices is connected to other control devices by means of a data bus. The control device includes a plurality of cells of the same type, each of which has a piece of reconfigurable hardware and peripheral modules. These cells can be reconfigured by configuration data, so that hardware connections for each cell can be adjusted to adapt to a desired control process. One or more cells together form a processor and/or interface modules.Type: ApplicationFiled: October 18, 2002Publication date: July 14, 2005Inventors: Thomas Forchert, Juergen Luka, Wolfgang Vieweger
