Vehicle Checker

Description

Vehicle Checker reviews a loaded vehicle test for missing, inconsistent, or unexpected test information and measurements. Use it as a data-quality aid before you calculate metrics or export a test summary.

When this feature is available

Vehicle Checker becomes available when the active test meets the requirements.

The active test must meet these conditions:

• The loaded test must be a vehicle test.
• Vehicle-test information must be available.
• The test must include at least one channel with a usable data status so WebSAT can associate the test information with the loaded test.

WebSAT enables Vehicle Checker for any successfully loaded vehicle test with the required test information and at least one usable channel. A complete instrumentation set is not required.

Settings

This feature has no settings.

How WebSAT processes the data

1. Identify the loaded vehicle-test type and select the matching regulatory or NCAP-style validation rules.
2. Check the test classification, identifiers, and required test information.
3. Check vehicle definitions, roles, and relationships to the test.
4. Check occupant definitions, seating locations, ATD information, and restraints.
5. Review instrumentation naming, units, axes, attachments, and channel status.
6. Check whether the signal sets needed for relevant injury metrics are present.
7. Organize missing, inconsistent, and unexpected data into user-facing findings.
8. Report the findings without editing the source test or substituting missing data.

How to interpret the results

This function does not calculate an injury metric or risk probability. A warning identifies a data condition that deserves review; it is not automatically a test failure. Resolve findings using the source laboratory record and the data requirements for the governing test procedure [1] [2].

Results

The results are organized into expandable sections:

• Test Check
• Vehicle Check
• Occupant Check
• Instrumentation Check
• Restraint Check
• Injury Metrics Check

The injury-metrics section groups expected signals by occupant and metric and can include channel tables plus explanatory messages. Empty or successful sections help distinguish a complete check from unavailable data.

The following example uses vehicle test 10099. Only sections containing results are displayed.

The Title section identifies the test reference number being checked.

The Vehicle Check section reports the vehicle records reviewed and any questionable vehicle measurements.

The Instrumentation Check section identifies channel records that may be duplicates or otherwise require review.

The left-front-seat Injury Metrics Check lists the available HIC, femur, and pelvis signals and identifies missing chest and TTI inputs.

The right-front-seat Injury Metrics Check applies the same signal review to the second occupant.
