Pre-Crash Safety Technology

Pre-crash safety technology is designed to assist the driver in averting collisions or reducing their severity in situations where they cannot be avoided.

Traffic Sign Recognition System (TSR)

Traffic Sign Recognition System (TSR)

Traffic Sign Display Indication

The following traffic signs are displayed on the active driving display/instrument cluster.

Speed limit signs (including auxiliary signs)

  1. Speed limit signs

  2. Auxiliary sign (example)

If the Forward Sensing Camera (FSC) cannot classify an auxiliary sign (such as time restrictions, turning restrictions, end of section) correctly, the following screen is displayed.

Do not enter signs

Stop signs

 

Speed limit signs (including auxiliary signs)

  • When the vehicle speed is about 1 km/h (0.6 mph) or faster, the speed limit sign is displayed when any one of the following conditions are met.

    • The Forward Sensing Camera (FSC) recognises a speed limit sign as a sign targeted for your vehicle and the vehicle passes it.

    • The speed limit sign stored in the navigation system is read.

  • In the following cases, display of the speed limit sign stops.

    • Each sensor determines that the vehicle has changed direction of travel.

    • The Forward Sensing Camera (FSC) recognises a new speed limit sign which differs from the previous one (displays the new speed limit sign).

    • The speed limit sign stored in the navigation system is not read within a certain period of time (if the Forward Sensing Camera (FSC) does not recognise a speed limit sign, the speed limit sign stored in the navigation system is displayed).

    • The vehicle speed exceeds the displayed speed limit sign by 30 km/h (19 mph) or more after a certain period of time has elapsed since the speed limit sign was displayed. (Except when there is information for the speed limit sign in the navigation system)

Do not enter signs

  • A do not enter sign is displayed when all of the following conditions are met.

    • The vehicle speed is about 80 km/h (50 mph) or slower.

    • The Forward Sensing Camera (FSC) recognises a do not enter sign as a sign targeted for your vehicle and the vehicle passes it.

  • When the Forward Sensing Camera (FSC) recognises the do not enter sign and a certain period of time has elapsed since the vehicle passed the sign, display of the do not enter sign stops.

Stop sign

  • A stop sign is displayed when all of the following conditions are met:

    • The vehicle speed is about 40 km/h (25 mph) or slower.

    • The Forward Sensing Camera (FSC) recognises a stop sign as a sign targeted for your vehicle.

  • When a certain period of time has elapsed since the stop sign was displayed, display of the stop sign stops.

Driver Attention Alert (DAA)

Driver Attention Alert (DAA)

The DAA is a system which detects driver fatigue and decreased attentiveness, and encourages the driver to take a rest.

When the vehicle is driven inside traffic lane lines at about 65 to 140 km/h (41 to 86 mph), the DAA estimates the amount of accumulated fatigue and decreased attentiveness of the driver based on the information from the Forward Sensing Camera (FSC) and other vehicle information, and encourages the driver to take a rest using an indication on the multi-information display and a warning sound.

Use the DAA on expressways or highways.

Refer to Forward Sensing Camera (FSC) (Search).

 

Do not rely completely on DAA and always drive carefully:

The DAA detects driver fatigue and decreased attentiveness and encourages the driver to take a rest, however, it is not designed to prevent the vehicle from straying. If you rely too much on the DAA it could lead to an accident. Drive carefully and operate the steering wheel appropriately.

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

  • The DAA operates when all of the following conditions are met.

    • The vehicle speed is about 65 to 140 km/h (41 to 86 mph).

    • The system detects white (yellow) lane lines.

    • The system has completed learning of the driver’s driving data after 60 minutes have passed since the driver began driving vehicle.

  • The DAA does not operate under the following conditions.

    • The vehicle speed is less than about 65 km/h (41 mph).

    • The vehicle speed exceeds about 140 km/h (86 mph).

    • The vehicle is making a sharp turn.

    • The vehicle is changing lanes.

    • The system cannot detect white (yellow) lane lines.

  • The DAA may not operate normally under the following conditions.

    • White (yellow) lane lines are less visible because of dirt or fading/patchiness.

    • The vehicle is jolted or swayed continuously by strong winds or rough roads.

    • The vehicle is driven aggressively.

    • When making frequent lane changes.

    • The vehicle is making a curve.

  • The DAA detects driver fatigue and decreased attentiveness based on the driving data when the vehicle is driven at about 65 to 140 km/h (41 to 86 mph) for about 20 minutes. The driving data will be reset under the following conditions.

    • The vehicle is stopped for 15 minutes or longer.

    • The vehicle is driven at less than about 65 km/h (41 mph) for about 30 minutes.

    • The ignition is switched off.

  • After the DAA has displayed the first message encouraging rest, it does not display the next one until 60 minutes have passed.
