System for detecting a mechanical fault in a rotating shaft
A new system is described that is able to detect mechanical failures in a rotating shaft or shafts such as those which may be found in an aircraft or other mechanical device or vehicle. The system comprises a first accelerometer provided on the rotating shaft to be monitored and a reference accelerometer provided elsewhere. The system can compensate information received from these accelerometers so as to determine a fault in the rotating shaft that is being monitored.
METHOD FOR MONITORING A HYDRAULIC BRAKE SYSTEM FOR A MOTOR VEHICLE AND BRAKE SYSTEM
A method for monitoring a hydraulic brake system for a motor vehicle, wherein a diagnostic valve is omitted and, instead, air volume and leakage are identified by a volume balance during generation of a dynamic pressure. An associated brake system is also disclosed.
Method and apparatus for providing location-aware wheel camber settings
An approach is provided for location-aware wheel camber settings. The approach involves, for example, collecting tire temperature data, wheel camber data, and location data from one or more sensors of a plurality of vehicles. The approach also involves processing the tire temperature data, wheel camber data, and location data to determine a target wheel camber for a road segment indicated by the location data. The target wheel camber is determined from one or more observed wheel cambers indicated in the wheel camber data. The target wheel camber is also associated with a target tire temperature indicated in the tire temperature data. The approach further involves storing the target wheel camber as an attribute of map data associated with the road segment.
TARGET VEHICLE FOR ADAS TESTING
A target vehicle, for example a two-wheeled vehicle, for mounting onto an ADAS (Advanced Driver Assistance System) testing platform is provided. The target vehicle comprises one or more sensors and an actuation assembly comprising an actuator. The sensors are arranged to measure a parameter relating to the dynamics of the target vehicle and may for example comprise accelerometers. The actuation assembly adjusts the tilt of the target vehicle in dependence on the output of the sensor(s), for example by means of a control unit. The tilting of the vehicle during cornering may thus be simulated. The measuring of such a parameter and the adjusting of the tilt may be conducted remotely from the testing platform. The sensor(s), control unit and actuator assembly may be self-contained within the target vehicle. A method of modeling a VRU (Vulnerable Road User) for ADAS testing is also provided.

Diagnostic baselining
Disclosed are methods and devices related to diagnosing a device-under-service (DUS) are disclosed. DUS-related data is received. The DUS-related data is determined to be aggregated into aggregated data based on a determined classification of the DUS-related data. An aggregated-data comparison of the DUS-related data and aggregated data is generated. The aggregated-data comparison can include a statistical analysis of the DUS-related data and/or a differential analysis of DUS-related data taken while the DUS is operating in two or more operating states. A DUS report is generated based on the aggregated-data comparison. The DUS report can include one or more sub-strategies. At least one of the one or more sub-strategies can include a sub-strategy-success estimate. The DUS report can be sent and a DUS-report display can be generated based on the DUS report.

LEAK-TIGHTNESS TESTING OF MOTOR VEHICLE BODIES
A method of leak-tightness testing a motor vehicle body that includes: a. fitting of electrically conductive contacts to at least one inner side of the motor vehicle body, and b. applying an electrical voltage between the contacts, c. applying water to at least a portion of at least one outer side of the motor vehicle body, and d. monitoring the voltage applied between the contacts to detect any drop in voltage that may occur, wherein at least one of the electrically conductive contacts comprises a lacquer composition comprising an organic binder and at least one electrically conductive additive.

Method and system for sending vehicle health report
Vehicle bus data is collected from an electronic control unit. User input is received to initiate creation of a vehicle health report for describing a vehicle diagnostic event. A voice message descriptive of a context of the diagnostic event is recorded. The telematics controller sends, to a sever, the vehicle health report including the voice message and a subset of the vehicle bus data including a time of the user input.
