- Test Procedures and Evaluation Methods for Seat Belt Reminder for Passengers Evaluation Test
The Passenger Seat Belt Reminder (PSBR) is a device that notifies the driver and others when a passenger other than the driver is not wearing a seat belt. The objective is to reduce the number of deaths and injuries by seeking to increase the seat belt use rate among passengers other than the driver. The testing confirms the operating conditions of the PSBR (the alarm timing, the alarm duration, types of alarm and display location, etc.).
Testing is carried out by checking whether requirements are met for the front and rear passenger seats.
The points are calculated from the difference between a visual alarm and auditory alarm for each seat.
If there are multiple seats, the score will be divided by the number of seats and the score will be the amount that can be confirmed.
The total score is used to perform evaluation on a five-level rating.
| Type of alarm | Visual alarm or auditory alarm | |
|---|---|---|
| Start of alarm | Front passenger seat | Within 60seconds, within 500m, or at a speed of under 25km/h after the car is in motion |
| Rear passenger seat | Depending on the specifications of the car manufacturer | |
| Duration of alarm | 30 seconds or more | |
| Length of alarm intervals | Must not be longer than 30 seconds | |
| Alarm for change of status | Emitting warnings immediately if the carʼs speed is faster than 25 km/h and seatbelts are not buckled | |
| Requirements | Point | |
|---|---|---|
| Visual Alarm & Audio Alarm | When the alarm indicator and the alarm sound can be confirmed from the driver seat | 0.9 |
| Audio Alarm | When the alarm sound can be confirmed from the front passenger seat | 0.6 |
| Requirements | Point | |
|---|---|---|
| Visual Alarm & Audio Alarm | When the alarm indicator and the alarm sound can be confirmed from the driver seat (the change of status alarm) | 0.9 |
| Visual Alarm | When the alarm indicator for the seat in question can be confirmed from the back seat (the rear seatbelt alarm) | 0.2 |
| When the alarm indicator for the seat in question can be confirmed from the back seat (the change of status alarm) | 0.2 | |
| Audio Alarm | When the audio alarm for the seat in question can be confirmed from the back seat (the rear seatbelt alarm) | 0.4 |
| When the audio alarm for the seat in question can be confirmed from the back seat (the change of status alarm) | 0.4 |
Based on the presence or absence of each seat and the total evaluation points for the passenger and rear seats, the evaluation is based on a maximum of 4 points.
| Level 5 | 3.16 points or more |
|---|---|
| Level 4 | 2.71 or more points and under 3.16 points |
| Level 3 | 2.26 or more points and under 2.71 points |
| Level 2 | 1.81 or more points and under 2.26 points |
| Level 1 | Under 1.81 |
Based on the presence or absence of each seat and the total evaluation points for the passenger and rear seats, the evaluation is based on a maximum of 100 points.
In addition, the score converted to a maximum of 8 points is displayed for collision safety performance evaluation.
| Level 5 | 90 points or more |
|---|---|
| Level 4 | 75 or more points and under 90 points |
| Level 3 | 60 or more points and under 75 points |
| Level 2 | 45 or more points and under 60 points |
| Level 1 | Under 45 |
