Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high costs associated with wireless data transmission between vehicles and support centers due to excessive data volume and the need for further reduction to lower costs and network load.
Innovation Solution
A method and device for transmitting vehicle-related data using allocation fields with settable indicators to dynamically allocate and transmit only necessary data fields, along with features like delta value transmission and network preference checking to minimize data size and optimize transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is transmitted in the form of XML or HTML documents between vehicle and support centre, then complete information can be transmitted, but transmission costs become considerably higher
Solution Approach 1:
The patent extracts and transmits only the specific data fields that are actually needed rather than transmitting complete XML or HTML documents. By identifying and extracting only the relevant portions of data required for vehicle monitoring and support functions, the system eliminates unnecessary data transmission while maintaining information completeness for critical parameters.
Solution Approach 2:
The patent segments the data transmission by dividing it into individual data fields rather than transmitting monolithic documents. Each data field can be independently identified, allocated, and transmitted based on its specific need, allowing the system to send only necessary information segments rather than complete documentation structures.
2Adaptability or versatility
If many data fields are transmitted including blank fields, then all possible information types can be covered, but message size becomes too large
Solution Approach 1:
The patent implements dynamic data field allocation where the structure of transmitted data adapts based on actual needs. Rather than using fixed monolithic message formats, the system dynamically determines which data fields are required for each transmission, allocating message structure in real-time based on vehicle status, driver log requirements, and operational context.
Solution Approach 2:
The patent applies local quality by allowing different parts of the data message to have different levels of detail and structure based on specific requirements. Each data field can be independently configured with appropriate precision and format, rather than applying uniform structure to all fields. This enables compact representation of critical data while omitting or simplifying less important information.
3Device complexity
If a fixed number of data fields are allocated in messages, then data structure is simple, but data allocation flexibility is reduced
Solution Approach 1:
The patent applies preliminary action by pre-defining a set of possible data field types and their structures, but delaying the actual allocation decision until transmission time. The system prepares the framework of possible fields in advance, then dynamically selects and allocates specific fields based on current vehicle status, driver log requirements, and operational context, achieving both structural simplicity and allocation flexibility.

AI summary
The present invention concerns a method, message handling device, vehicle, vehicle support centre, computer program product and signal for transmission of vehicle related data between a vehicle and a vehicle support centre. The method provides an allocation field (AF) including settable allocation indicators (Fl, F2, F3, F4, F5,.., Fn), each corresponding to a different type of data, sets at least one allocation indicator (F2, F4, F5, Fn) for a corresponding type of data (D2, D4, D5, Dn), creates a data segment (DS) comprising the allocation field and a number of data fields (DFl, DF2, DF3, .., DFm), which number is based on the allocation indicator setting, allocates each data field to a type of data (D2, D4, D5, Dn) according to the allocation indicator setting, fills each data field with data of the allocated type, and transmits a data message between the vehicle and vehicle support centre comprising said segment.
