摘要： The present disclosure relates to operating Electronic Control Units (ECUs) of a vehicle in a fail-safe mode. The vehicle is controlled by a control system comprising a plurality of primary ECUs and a plurality of back-up ECUs backing-up the plurality of primary ECUs. Each back-up ECU comprises a migration map comprising a list of the plurality of back-up ECUs and corresponding primary ECU. The migration map may be shared between each other ECU from the plurality of back-up ECUs. Each ECU is configured to update the migration map based on availability of back-up ECU for corresponding primary ECU. If unavailable or if any failure of any back-up ECU, the migration map is updated, and new back-up ECU is determined in place of unavailable/ failure back-up ECU. The updated migration map is used by the plurality of back-up ECUs for determining the updated back-up ECUs.

摘要： The present subject matter relates to a control unit and a method for controlling the temperature of a fuel-fed prechamber of an ignition device included in an internal combustion engine. In order to avoid inadmissible high temperatures of the prechamber, a targeted injection is introduced into the main combustion chamber during the compression stroke and/or into the prechamber depending on the prechamber temperature. Introducing an injection into the main combustion chamber at the end of the compression stroke can reduce the temperature of the gas mixture in/around the prechamber and therefore help to control the prechamber temperature at moderate increased temperatures without negatively affect the particle emissions. Hence, a cooling injection directly into the prechamber, which may cause drawbacks regarding particle emissions, is only necessary when the prechamber temperature is strongly increased.

摘要： The present invention relates to a method and a control unit for avoiding condensation of humidity in an intake system of an internal combustion engine after engine switch off. Condensed liquid in the intake system of the stopped engine can lead to icing, corrosion and a hydrostatic lock at the next engine start. To prevent such an engine damage, it is necessary to determine if and in which amount condensed liquid occurs in the cooled intake system and to initiate appropriate actions to eliminate the liquid therefrom. The present invention predicts the occurrence of condensation in the intake system of the cooled engine and initiates corrective measures at engine switch off and during the cooling down period.

摘要： A vehicle control method and system which periodically acquires a plurality of images from a plurality of cameras. Pixels are identified in each image which have a unique feature compared to surrounding pixels in the image. A three-dimensional point map is then reconstructed with the characteristic three-dimensional points based upon the unique pixels in the picture. The motion of the characteristic three-dimensional points from a first frame and to a second frame at a subsequent time is constructed so that at least one of the yaw, pitch, roll, or heave rate of the vehicle is calculated based upon the motion of the characteristic three-dimensional points in the three-dimensional point map.

摘要： The present disclosure relates to a method and a control unit for controlling pre-warming process of an engine of a Hybrid Electric Vehicle (HEV). The method comprises determining start-up time of the engine. The method also comprises determining engine heating time for the engine. The pre-warming process of the engine is initiated prior to start up time of the engine. The process of pre-warming is discontinued when the determined start-up time of the engine is greater than the engine heating time and the process is restarted when the determined start-up time of the engine is less than the engine heating time and when the pre-warming process of the engine is discontinued. The above-mentioned process is reiterated at plurality of time intervals for controlling the pre-warming process of the engine which results in energy efficiency and sufficient heat for warm-up of the engine.
