Vehicle Diagnostic Scanner Jobs for Faster Multi-System Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diagnostic tools for vehicles require technicians to navigate multiple user interface screens to perform scan tool functions across different vehicle systems, leading to inefficiencies in accessing and executing scanner jobs, as they need to identify various systems and components, which can be time-consuming and complex.
Innovation Solution
A diagnostic tool system that includes processors, displays, and computer-readable mediums to transmit Vehicle Data Messages (VDMs) to identified vehicle systems, with user-selectable controls on the interface allowing technicians to perform scanner jobs efficiently by displaying relevant screens and guidance directly, enabling transmission of VDMs to specific components without needing to navigate through multiple screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If technicians navigate through multiple user interface screens to access scan tool functions for different vehicle systems, then they can perform comprehensive diagnostics, but the time required to complete diagnostic tasks increases significantly
Solution Approach 1:
The system pre-configures and stores multiple sequences of scan tool functions as reusable templates associated with specific scanner jobs (e.g., brake system diagnostics, engine diagnostics). When a technician selects a scanner job, the corresponding pre-configured sequence is automatically executed, eliminating the need to manually navigate through multiple screens and perform each diagnostic step individually.
2Adaptability or versatility
If the diagnostic tool provides access to multiple menus of functional tests across different vehicle systems, then the versatility of the tool increases, but the complexity of the user interface and navigation increases
Solution Approach 1:
The diagnostic system segments the comprehensive scan tool functions into organized scanner jobs, each representing a specific diagnostic task (e.g., brake system, engine, transmission). Each scanner job contains a predefined sequence of relevant functional tests for that specific system, allowing technicians to access only the necessary functions for the current diagnostic task without being overwhelmed by the entire menu structure.
Solution Approach 2:
The scanner job template mechanism provides a universal solution that can be applied across different vehicle systems and diagnostic scenarios. The same template framework accommodates various diagnostic sequences for different systems (brakes, engine, transmission), making the interface consistent and predictable regardless of which diagnostic task is being performed.
3Measurement precision
If technicians need to identify multiple vehicle systems before accessing functional tests, then accurate system identification is achieved, but the number of steps required to perform diagnostics increases
Solution Approach 1:
The system performs preliminary identification of the vehicle system as part of the scanner job configuration process. When a technician selects a scanner job, the associated sequence is already configured with the correct system identification parameters, eliminating the need for the technician to manually identify and select each system before accessing functional tests.
Data Source
AI summary
A diagnostic tool includes a processor, display, and memory storing instructions to perform scan tool functions (STF) including transmitting a message to a vehicle. The STF include first STF for a first system of the vehicle. Additional stored instructions are executable to display a first user-interface screen (UIS) including a first user-selectable control (USC) including an indicator of a first scanner job performable on the vehicle, and to display a second UIS instead of the first UIS in response to a selection of the first USC. The second UIS incudes: a second USC including an indicator of the first STF for the first system of the vehicle, and guidance for performing a procedure of the first scanner job. The stored instructions are executable to transmit a first vehicle data message to a component of the first system in response to a selection of the second USC.
