The proposed AutoSafe™ method converts evidence from twelve technical domains into an A–F class decision. A class is not based on total points alone.
Each letter grade requires the applicable total-points threshold, the required floor in every domain, all mandatory gates and any class-specific requirements. This section explains the proposed point calculation and the separate checks required before a vehicle can receive an AutoSafe™ Class A through F. The numerical values remain proposed policy values pending the validation and release conditions in Annex F.
Class Decision at a Glance
AutoSafe™ uses a proposed 1,000-point schedule across twelve domains, followed by floor, gate and class-specific checks.
Total points + every-domain floors + mandatory gates + class-specific requirements
No high score in one area can compensate for a failed domain floor or a valid mandatory-gate failure.
Twelve-Domain Point Schedule
For readability, the twelve standard domains are shown below in seven related website groups. The stated point allocations are proposed and remain subject to technical validation.
| Domain | Standard domains | Decision role |
|---|---|---|
|
Frontal, Side, Rear & Rollover Protection Cabin integrity & biomechanical injury metrics. |
D03–D04 · 250 pts | Points + floor |
|
Occupant Diversity & Child Protection Protection for all seating positions and age groups. |
D05 · 90 pts | Points + floor |
|
Vulnerable Road User Impact Protection Passive and impact-activated head, pelvis, lower-extremity and local-zone protection. |
D06 · 80 pts | Points + floor |
|
Safe Driving, Human Factors & Crash Avoidance Driver monitoring and human factors plus measured crash-avoidance performance. |
D01–D02 · 190 pts | Points + floor |
|
Functional Safety, Cybersecurity & Software Integrity Functional and intended-function safety plus cybersecurity and software integrity. |
D08–D09 · 120 pts | Points + floor |
|
Energy, Electrical & Fire Safety Architecture-applicable containment, isolation, fire and energy-hazard evidence. |
D07 · 100 pts | Points + floor |
|
Post-Crash, Production Equivalence & Evidence Quality Post-crash rescue and escape, initial production equivalence, and reproducible evidence. |
D10–D12 · 170 pts | Points + floor |
The point schedule is proposed in this Draft for Technical Review. Release values, indicators and validation items remain governed by the standard and Annex F.
Calculation Phases
The AutoSafe™ scoring engine follows a clear, five-phase sequence from raw test data to final class.
-
Domain Scoring
Evidence is scored against the indicators allocated to each of the twelve domains. -
Point Total
Domain points are summed to a proposed maximum of 1,000 points. -
Gate and Class Checks
Every-domain floors, common gates and class-specific gates are checked independently of the point total. -
Class Mapping
The result must then satisfy every-domain floors, mandatory gates and class-specific requirements. -
Compliance & Production Check
Initial production equivalence evidence confirms that the assessed configuration represents production.
AutoSafe™ Classes A–F – Interpretation
Highest AUTOSAFE class within the stated assessment envelope.
- Requires the released Class A extended assessment envelope.
- All domain floors, common gates and Class A conditions must be satisfied.
- Does not imply injury-free or fatality-free operation.
Score band: 920 points + at least 85% in every domain, with all applicable gates and Class A requirements satisfied.
Enhanced protection with additional validated test requirements.
- Requires its additional physical and occupant-diversity evidence.
- All domain floors, common gates and Class B conditions must be satisfied.
- A Class A-specific limitation may cap a result at B only when every B condition is met.
Score band: 850 points + at least 75% in every domain, with all applicable gates and Class B requirements satisfied.
Advanced protection under the AUTOSAFE core and robustness programme.
- Requires the released core and robustness test programme.
- All domain floors, common gates and Class C conditions must be satisfied.
- A favourable total cannot compensate for an unmet gate or domain floor.
Score band: 760 points + at least 65% in every domain, with all applicable gates and Class C requirements satisfied.
Intermediate assessed performance with disclosed limitations.
- Requires at least 650 points and a 55% floor in every domain.
- Applicable common gates and Class D requirements must be satisfied.
- Limitations must be disclosed with the assessed configuration and scope.
Score band: 650 points + at least 55% in every domain, with all applicable gates and Class D requirements satisfied.
Lowest qualifying assessed performance class.
- Requires at least 500 points and a 40% floor in every domain.
- All applicable common gates and Class E requirements must be satisfied.
- It remains a qualifying result, distinct from an adverse Class F finding.
Score band: 500 points + at least 40% in every domain, with all applicable gates and Class E requirements satisfied.
Assessed performance below the qualifying E threshold or a specified valid common-gate failure.
- Class F is not an approval mark.
- Incomplete evidence, no application or an unfinished assessment remains unrated.
- Where a common-gate failure establishes F early, incomplete areas are disclosed and no invented total is shown.
Score band: Below Class E, or a valid common-gate failure. Incomplete or insufficient evidence is unrated, not Class F.
Gates & Class Conditions
The total alone does not establish a class. Domain floors, mandatory common gates and class-specific requirements are recorded and applied separately.
- Common gates: a valid failure can require an adverse Class F result.
- Domain floors: every domain must meet the floor for the claimed class.
- Class-specific requirements: higher classes may require additional tests or evidence.
Transparency & Publication
After programme release, an eligible assessment may receive a Vehicle Test and Rating Certificate, supporting report and authorised label record.
- Published: class (A–F), total score and domain breakdown.
- Documented: modifiers or caps only where explicitly specified by the released protocol, together with gate and class-condition reasoning.
- When operationally authorised, the label verification reference would point to the authoritative rating record.
The proposed publication model separates a sufficiently informative public scorecard from security-sensitive or proprietary evidence held under controlled access.
