Vehicle Service Field Display for Adaptive Maintenance Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Condition Based Service (CBS) systems lack flexibility in displaying service information to drivers, often showing irrelevant maintenance requirements and failing to alert drivers to critical maintenance needs in a timely manner.
Innovation Solution
The Condition Based Repair system dynamically controls the display of service fields by only showing the status of service-relevant components when their condition is not up to standard, using a teleservice module to transmit data to service centers when necessary, and employing a client and master unit to process sensor data and determine when to display alerts based on threshold values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed scheme of displayed fields is used for all service events, then the display structure is simple and consistent, but the system cannot adapt to different driving habits and service requirements, leading to irrelevant information being displayed or critical maintenance needs being missed
Solution Approach 1:
The display system transitions from a static fixed scheme to a dynamic adaptive scheme where service fields are selectively displayed or hidden based on real-time assessment of service relevance. The system dynamically adjusts the display content by comparing current vehicle status against service criteria, showing only those service events that are relevant to the driver's specific driving habits and vehicle condition.
Solution Approach 2:
The system changes the display parameter (visibility of service fields) based on assessed service relevance. Each service field's display state is controlled by a boolean parameter that switches between visible and hidden states according to whether the corresponding service event meets the display criteria, which are determined by driving habits analysis and service requirements.
2Loss of information
If all service fields are displayed continuously, then complete service information is provided, but drivers are overwhelmed with irrelevant information and critical alerts are not noticed timely
Solution Approach 1:
The system extracts and displays only the relevant service information from the complete set of service events. By assessing service relevance based on driving habits and vehicle status, the system separates critical maintenance needs from routine service items, displaying only those that require driver attention while keeping complete service data available for dealer assessment.
Solution Approach 2:
Instead of displaying all service fields (excessive action), the system displays only the necessary subset of service fields (partial action) that are relevant to current driving conditions and service requirements. This partial display approach prevents information overload while ensuring critical maintenance needs are communicated.
3Device complexity
If service fields are displayed based on threshold values only, then the control logic is simple, but the system cannot provide tailored maintenance information adapted to individual driving standards
Solution Approach 1:
The system performs preliminary assessment of service relevance by analyzing driving habits and comparing them against service criteria before determining display requirements. This preliminary action enables the system to pre-identify which service fields should be displayed for each driver, allowing the simple threshold-based display control logic to work with adaptively determined display sets.

AI summary
The present invention provides a system and method for controlling the display of service fields. In an exemplary embodiment, a system for controlling the display of at least one service field about the status of at least one service-relevant component of a vehicle, comprises: a display configured to display said service field; a master connected to said display; an electronic control unit (ECU) comprising a client; and at least one sensor connected to said client and configured to sense the status of said component, wherein said master is configured to control the display to display said service field about said status only when said status is not up to a standard. An associated method is also disclosed. The proposed solution in this invention can flexibly display the service filed about the status of the service relevant component, thus enabling the driver to easily recognize the status of the vehicle.
