Patent number: 9026711Abstract: A control system includes a gateway controller and a remote controller. The gateway controller is configured to embed an HTTP request in a CAN bus-compatible message and transmit the CAN bus-compatible message onto a CAN bus. The remote controller is configured to receive the CAN bus-compatible message from the CAN bus, extract the HTTP request from the CAN bus-compatible message, and create an HTTP response to the HTTP request.Type: GrantFiled: December 12, 2012Date of Patent: May 5, 2015Assignee: Lear Corporation GmbHInventor: Matthias Kessler

Patent number: 8994278Abstract: A device serves to control an electrical load of at least two single loads connected in series. Each of the at least two single loads is connected in parallel to a controllable switch, so that each of the at least two single loads can be switched independently of one another. In addition, a driver stage that drives a current into the electrical load is present. The controllable switches can be controlled by the control unit. A dummy load is connected in series to the at least two single loads.Type: GrantFiled: March 10, 2011Date of Patent: March 31, 2015Assignee: Lear Corporation GmbHInventors: Klaus-Dieter Grebner, Michael Reier

Patent number: 8659235Abstract: A current source and an associated method for supplying current to a load such as an arrangement of LEDs. The intensity of the supplied current varies as a function of the temperature of the load. The intensity of the current is temperature-dependent and limited to a predefined maximum. The temperature dependence is achieved by the component parts that are used without the help of special temperature sensors. The current source is supplied with a reference voltage derived from an integrated circuit. The reference voltage is tapped from a port of the IC and therefore it is switchable. The reference voltage is used to produce a control current, which is fed through a driver stage to produce the current of the current source. Elements in the current source limit the current's intensity and change it as a function of temperature.Type: GrantFiled: March 4, 2010Date of Patent: February 25, 2014Assignee: Lear Corporation GmbHInventors: Gerd Vogler, Ingo Simanek, Fried Berkenkamp

Patent number: 8513896Abstract: A method for control and discharge control of an electrical load, in which the control and discharge occurs by means of a control frame and a discharge frame, and in which one control frame and one discharge frame represent one switching cycle for the electrical load. A plurality of switching cycles are arranged following one another, wherein a controllable switch is connected in parallel to each point load so that each point load can be switched independently of the other point load during the switching cycle. A control unit monitors the electrical current flowing in the electrical load, and the control unit uses an actual/setpoint comparison to control the current to an adjustable setpoint so that a current that is as constant as possible flows into the electrical load. The controllable switches switch on the point loads during the control frame of a switching cycle, and the controllable switches switch off the point loads during the discharge frame of a switching cycle.Type: GrantFiled: May 24, 2010Date of Patent: August 20, 2013Assignee: Lear Corporation GmbHInventor: Klaus-Dieter Grebner

The DC/DC converter includes an input capacitor, an inductor, an electronic switch, a diode, an output capacitor and a control unit, wherein the control unit controls the first electronic switch as a function of the signals fed to the control unit. The input capacitor is connected between the input voltage and ground or zero point, and the inductor is connected between the input capacitor and the electronic switch. A second electronic switch, which the control unit can drive by means of a switching signal, is disposed between the load and the ground or zero point, and a second diode embodies a connection between the output of the load and the input capacitor. The control unit is fed the value of the input voltage.Type: GrantFiled: May 24, 2010Date of Patent: January 22, 2013Assignee: Lear Corporation GmbHInventor: Klaus-Dieter Grebner

Patent number: 8049510Abstract: Multiple embodiments relate to a method for detecting a fault on a data line in a bus system in a two-line data network having at least two control units. A data signal is emitted by a transmitter-receiver unit on the two data lines as a differential voltage signal that includes a defined quiescent current. The data lines are mutually connected through a resistance bridge for detecting the middle voltage. The middle voltage is detected directly by a microcontroller after a low-pass filter or as a digital value after an analog-to-digital conversion. The result is displayed and/or stored. A circuit arrangement for implementing the method is also provided.Type: GrantFiled: July 14, 2009Date of Patent: November 1, 2011Assignee: Lear Corporation GmbHInventor: Matthias Queck
