摘要:
A system and method for monitoring the state of health of vehicle components, sub-systems and systems on board the vehicle and/or remotely, and use collected information and data about the vehicle to establish a database for the vehicle as to the state of health of the various components, sub-systems and systems. When a customer brings a vehicle to a service center or dealership complaining about a particular problem, and the service center wishes to replace a part associated with that problem, the OEM or manufacturer can authorize or reject the replacement of the part based on review of the database as to the known state of health of the part. Therefore, only parts which may not be healthy will typically be authorized for replacement. Also, the database can be made available to customers for customer concern resolving.
摘要:
Information associated with vehicle components and sub-systems is monitored by an on-board module, and associated data, either processed or raw, is telematically transmitted to a remote data center by wireless communications. The remote data center archives the received data in a database for each separate vehicle that is part of the system. The remote data center analyzes the data to ascertain whether the data indicates a usage pattern and/or vehicle condition that may have a detrimental effect on certain vehicle components, sub-systems and systems, such as excessive component wear. For example, the data center runs pattern detection algorithms on the data to identify known usage patterns that may potentially impact normal vehicle operation. If such a usage pattern is detected, the remote data center may issue a warning to the vehicle operator, or other designated person, that such usage may have a detrimental effect on the vehicle or vehicle components.
摘要:
A system and method for telemetrically collecting on-road vehicle diagnostic data. In one embodiment, the method includes collecting vehicle diagnostic data from service shops, on-road vehicles and warranty records, aggregating the collected data and extracting knowledge therefrom. The extracted knowledge can be used to enhance algorithms on-board vehicles or at service centers so as to better identify vehicle faults and provide enhanced diagnostics and prognostics. The enhanced algorithms can then be used to provide predictive maintenance suggestions, provide trouble shooting assistance or provide vehicle design improvements.
摘要:
A system and method for determining the status of a vehicle battery to determine whether the battery may not have enough charge to start the vehicle. The method includes collecting data relating to the battery on the vehicle and collecting data relating to the battery at a remote back-office. Both the vehicle and the remote data center determine battery characteristics based on the collected data and the likelihood of a vehicle no-start condition, where the algorithm used at the remote back-office may be more sophisticated. The data collected at the remote back-office may include vehicle battery information transmitted wirelessly from the vehicle, and other information, such as temperature, battery reliability, miles that the vehicle has driven per day, ambient temperature, high content vehicle, etc. Both the vehicle and the remote back-office may determine the battery open circuit voltage.
摘要:
Parasitic loads on a vehicular battery are evaluated based on an estimated reduction in the state of charge of the battery over the course of an engine-off state.
