Driver Monitoring (DM)

The DM is a system which detects driver fatigue and sleepiness, and encourages the driver to take a rest.

While driving the vehicle at about 5 km/h (3 mph) or faster, the DM detects changes in the driver's facial features using the driver monitoring camera. The system then estimates the amount of accumulated fatigue and sleepiness of the driver and encourages the driver to take a rest using a warning indication in the instrument cluster and a warning sound.

Two types of warning indication patterns are set for notifying the driver based on the estimated amount of accumulated fatigue and sleepiness of the driver.

  • Fatigue and sleepiness are detected: Warning pattern (caution)

  • Much more fatigue and sleepiness are detected: Warning pattern (warning)

 

Do not rely completely on the DM and always drive carefully:

The DM is a system which detects driver fatigue and sleepiness, and encourages the driver to take a rest. This is not designed to prevent driver fatigue and sleepiness, and over-reliance on the system could lead to an accident. Drive carefully and turn the steering wheel appropriately.

In addition, the system may not be able to detect driver fatigue and sleepiness correctly depending on the traffic and driving conditions. The driver must take sufficient rest in order to drive safely.

Operation conditions

The DM begins monitoring after 20 minutes have passed since the driver began driving the vehicle and when the vehicle speed is about 5 km/h (3 mph) or faster.

 

  • If the vehicle speed decreases to less than about 5 km/h (3 mph) while the DM is monitoring, the DM stops monitoring for 6 minutes even if the vehicle speed returns to about 5 km/h (3 mph) or faster.

  • If the driver monitoring camera does not recognize the driver correctly, the DM may not monitor correctly.

    Refer to Driver Monitoring Camera (Search).

  • After the DM has displayed the first message encouraging the driver to take a rest, it does not display it again during the following periods.

    • After displaying the warning pattern (caution), the next warning pattern (caution) is not displayed until 45 minutes have passed.

    • After displaying the warning pattern (warning), the next warning pattern (warning) is not displayed until 15 minutes have passed.

    • After displaying the warning pattern (warning), the next warning pattern (caution) is not displayed until 45 minutes have passed.
