| 20080258253 | Integrated Microprocessor System for Safety-Critical Regulations - Disclosed is an integrated circuit arrangement for safety-critical applications, such as for regulating and controlling tasks in an electronic brake system for motor vehicles. The arrangement includes several electronic, cooperating functional groups ( | 10-23-2008 |
| 20080312790 | Electronic Motor Vehicle Control Unit - Control unit for motor vehicle brakes composed of conventional function groups with an electronic brake controller and a hydraulic unit that is in particular rigidly connected to the controller, with the electronic controller comprising a redundant or partly redundant microprocessor system with several central processing units (CPU), and with the conventional function groups including a control philosophy at least for anti-lock control. Furthermore, the control unit comprises non-conventional hardware and software function groups of an otherwise external motor vehicle passenger protection safety system, which in particular does not intervene directly into driving dynamics, hence, is passive. These groups are integrated into the ambience of the control unit for motor vehicle brakes, and ambience implies that the non-conventional hardware and software function groups to be integrated are arranged at least in the immediate vicinity of the conventional electronic brake controller. | 12-18-2008 |

| 20100107006 | Method and Semiconductor Memory With A Device For Detecting Addressing Errors - A semiconductor memory and a data processing system having hardware for carrying out a method for the improved internal monitoring of addressing circuits in semiconductor memories or in a data processing system, in which logic levels addressing lines are tapped off, the actually selected address or subaddress is represented by additional address bit lines, the actually accessed address/subaddress is recovered using the address bit lines, and the actually selected address/subaddress is compared with the applied address/subaddress, obtained from the additional address bit lines, in order to recognize an error in the addressing circuit. | 04-29-2010 |
| 20100114446 | Motor Vehicle Electric System - A motor vehicle control system having a coil switch which is connected to the vehicle electric system is intended to permit reliable operation of a coil switch without power losses in the semiconductor switches. For this purpose, a step-up converter is connected between the vehicle electric system and the coil switch. | 05-06-2010 |
| 20100176866 | Signal Preprocessing Device Comprising Band-Pass Filters For Structure-Borne Noise Sensors - A signal preprocessing device is disclosed, which is integrated into a structure-borne sound sensor or into an acceleration sensor for sensing structure-borne sound, or which is connected at the input end to at least one sensor of this type and is connected at the output end to at least one signal channel that is connected to at least one central electronic control unit, and wherein the signal preprocessing device has at least one filter module having at least two bandpass filters. | 07-15-2010 |
| 20110057645 | Method and Pulse-Width-Modulated Current Control Circuit For Driving Inductive Loads in Motor Vehicles - Method in which the current is measured inside an integrated PWM control circuit using at least one A/D converter which is likewise integrated in the circuit is described. The PWM controller is provided for the purpose of driving inductive loads and is arranged, in particular, in an electronic circuit of an electronic controller for a motor vehicle braking system. Before determining the actual current of the PWM controller, which is determined using the at least one A/D converter, the current is smoothed using a low-pass filter. A circuit arrangement for carrying out the above method and its use in electronic motor vehicle control systems is also described herein. | 03-10-2011 |
