The disclosure relates to a method to test a state of an electrical system, in particular, of an electrical energy supply system, of a motor vehicle. In order to permit electronically automated testing of a state of the electrical system, or the system components of the motor vehicle, during testing of at least one electrical component of the system, at least one electrical property of this electrical component is detected electronically during variation of at least one electrical property of at least one further electrical component of the system. The individual electrical components of the system are detected electronically, and a deterministic test sequence to sequentially test the individual electrical components on the basis of the electrical components present is generated electronically, in which the test sequence is carried out electronically in an automated fashion.

Systems and methods for improving fuel economy in vehicles such as Class 8 trucks are provided. In some embodiments, signals indicating states of the powertrain are collected and used to generate fuel rate optimization values. Fuel rate optimization values may indicate a difference between optimum fuel flow rates and actual fuel flow rates during a vehicle drive cycle. Recorded fuel rate optimization values may be used to compare different vehicle configurations during testing, and may also be used to evaluate vehicle performance during real-world operation.

A vehicular ECU (electronic control unit) is any one of a plurality of vehicular ECUs connected to an in-vehicle network in a vehicle and includes: a service interface, a service bus, and a service manager. The service interface issues a request of service that uses a function installed in a different vehicular ECU based on a request from the application, and makes the application generate a service as a response to a request of service from the different vehicular ECU. The service bus transmits and receives a message corresponding to a request of service and a response by using a predetermined protocol between the service interfaces of the vehicular ECU and the different vehicular ECU. The service manager achieves the service to be dynamically and interoperably used by managing a position of the service.

A system aggregates data related to a non-conformance system in an aircraft and allocates resources to repairing the non-conformance condition. The system includes a service bus that receives and distributes the non-conformance condition and an optimizer tool that generates repair alternatives. The optimizer tool allows dynamic reconfiguration of rules to activate and deactivate or change a weight of individual rules in a rule set.
