摘要:
A method and system for a wireless interface to the electronics of an automotive vehicle for a remote application in the vehicle or within communication range of the vehicle. The remote application may be a navigation system using vehicle motion sensor data to provide or improve a navigation solution for the vehicle. In an alternative embodiment, the remote application is diagnostic software running on a handheld computer that evaluates vehicle systems in a diagnostics procedure.
摘要:
A method and a device for event interpretation and output of operating instructions in motor vehicles are described. The inventive idea is to bundle the wealth of information regarding errors and/or defects resulting from the multitude of sensors and the complexity of modern vehicles, optionally linking it with empirical findings and outputting operating instructions to the driver, so that the instructions do not make excessive technical demands of the driver but instead are adapted to his/her instantaneous situation. The core of the inventive concept is to use an electronic database which contains the technical information including the error codes of devices of the automotive sensor and electronic systems for analysis of event information which informs the driver comprehensively and yet comprehensibly regarding the problems that have occurred. Likewise the database may be the target of an inquiry initiated by the driver.

摘要:
A method for recording data from parameter values captured using sensors in a vehicle, particularly for the reconstruction of accidents, as well as a memory device and a device for recording such data, it being possible to record all relevant data continuously using low memory volume, and to save it permanently in a short period of time. For this purpose, the parameter values and/or data calculated from them are recorded at increasing time intervals for the instantaneous capturing point in time at decreasing density. A suitable storage device has a RAM (random access memory) for recording the data in each case over a certain time space and in a nonvolatile memory (such as EEPROM), to which the recorded data can be transmitted in parallel from the RAM within a few ms. An ASIC is suitable for its implementation.

An energy storage device for generating an n-phase supply voltage includes a plurality of energy supply branches that are connected in parallel, each of which is connected to an output connector of the energy storage device. Each of the energy supply branches includes a plurality of energy storage modules that are connected in series, each having at least one energy storage cell, and having a plurality of coupling modules connected to one of the plurality of energy storage modules, respectively, each configured to couple, or to bridge, the connected energy storage module with the energy supply branch. The energy storage device further includes a control system.

摘要:
A method and a device for acquiring performance quantities of a product, in particular until its technical failure, and for determining the remaining service life of the product are described. The determination of the remaining service life of the product, acquisition of service lives of the products and determination of service life threshold values are performed on the basis of performance quantities subdivided into classes (classified). Weighting factors are determined first and then these weighting factors are used to determine weighted, cumulative service lives and service life threshold values. The reliability of products is monitored in mass production.
摘要:
In a method and system for estimating a trajectory of a vehicle having an Electronic Stability Program (ESP), sensor data pertaining to dynamics of the vehicle is obtained, and an estimate of the trajectory of the vehicle is calculated using the sensor data and vehicle dynamics parameters estimated by the ESP. The acquisition of the sensor data and the calculation of vehicle trajectory estimates occur independently of any external signal communication infrastructure-based trajectory estimation tools.
摘要:
A method and system is provided for a protocol translation device that may include two different protocols and an intermediate, network-independent protocol. In an embodiment, an emerging worldwide standard, Bluetooth, provides a wireless interface to the electronics in an automotive vehicle via the de-facto standard for vehicle buses, Controller Area Network (CAN). A remote application can connect to this interface via a Bluetooth host in the vehicle or in communication range of the vehicle.
摘要:
A method and a control unit for operating an internal combustion engine of a motor vehicle are provided, in particular for controlling/regulating the internal combustion engine as a function of an air-mass sensor signal from a first air-mass sensor. A first auxiliary signal, which is obtained arithmetically from an additional sensory system or from models of the internal combustion engine, allows a plausibility control or the substitution of the air-mass sensor signal in the case of signal interference of the air-mass sensor signal, and thereby ensures that the internal combustion engine is able to continue working in the optimal operating point.
