  • Publication number: 20180197413
    Abstract: A method to manage a parking area by a system in connection with the vehicle is provided. The system is designed to enter into connection with a vehicle that is looking for a parking space, and to assign a parking position to the vehicle. The system registers available parking room on the basis of an entropy calculation, wherein, within a parking area, both an a priori entropy prior to parking the vehicle and an a posteriori entropy are evaluated for a specific parking position, in order for a parking position to be assigned to the vehicle that brings about the lowest possible entropy on the parking area.

  • Publication number: 20170132118
    Abstract: A method and an apparatus for testing software for autonomous vehicles by means of a loop simulation involves hardware in the form of one or more real autonomous vehicles able to carry out autonomous test drives in the real world. In response to a work order given by a user, a check is automatically carried out in order to determine which vehicles, among a plurality of real autonomous vehicles which are able to carry out autonomous test drives on globally distributed test tracks in the real world, are currently available for one or more tests defined in the work order. The performance of the software tests and the test drives is then automatically planned and coordinated.

  • Publication number: 20170132117
    Abstract: Test cases for autonomous vehicles are generated automatically by using data which have been collected from vehicles participating in public road traffic. A test planning system for autonomous vehicle includes defined application cases for autonomous vehicles. The vehicles are configured to identify test cases with prediction analyses of a reference catalogue of driving situations and the defined application cases, and compare, via a comparative analyses, the test cases and the defined application cases to compile an expanded set of test cases, wherein the expanded set of test cases are compared to the defined application cases to output a complete set of test cases. The system also includes a central database configured to query the complete set of test cases.

  • Publication number: 20170058792
    Abstract: A method for regulating the charge pressure pboost of a supercharged internal combustion engine is disclosed. The method may include adjusting each of two wastegates, a variable turbine geometry, and a downstream compressor bypass valve to regulate engine boost pressure as a function of a first setpoint value for pressure between compressors and a pressure difference in a first regulation loop, a second setpoint value for pressure downstream of multiple compressors, and the pressure difference in a second regulation loop.

  • Patent number: 9303556
    Abstract: A method for operating a turbocharger arrangement of an internal combustion engine, the turbocharger arrangement comprising a low-pressure and a high-pressure turbocharging stage arranged sequentially, the low-pressure turbo-charging stage comprising a low-pressure turbine with a sensorless low-pressure turbine bypass valve, is provided. The method comprises evaluating at least one sensor signal of the turbocharger arrangement for detecting a failure mode of the sensorless low-pressure turbine bypass valve. In this way, the low-pressure turbine bypass valve may be monitored for degradation without utilizing a position sensor.

  • Patent number: 9169796
    Abstract: Methods are provided for controlling an engine. One method may include adjusting airflow to a turbocharger arrangement with a turbine bypass valve bypassing a first turbine from a high-pressure turbocharger and a wastegate bypassing a second turbine from a low-pressure turbocharger; responsive to valve degradation, setting the turbine bypass valve fully open and the wastegate fully closed; and limiting engine torque based on a flow through a compressor of the low pressure turbocharger. In the event of valve degradation, limiting torque may reduce overspeed and surge of the low pressure turbocharger.
