Warning phase 1
If driving operations are not detected after the hands off steering wheel warning operates, a buzzer will sound intermittently and a message will be displayed to warn the driver, and the system will judge if the driver is responsive or not. If driving operations, such as holding the steering wheel, are not performed within a certain amount of time, the system will enter warning phase 2.
Depending on the type of detection of the driver’ s unresponsiveness, the system may skip warning phase 1 and start the control of warning phase 2.
Warning phase 2
After entering warning phase 2, a buzzer will sound in short intervals and a message will be displayed to warn the driver, and the vehicle will slowly decelerate. If driving operations, such as holding the steering wheel, are not performed within a certain amount of time, the system will determine that the driver is not responsive and enter the deceleration stop phase.
When the vehicle is decelerating, the brake lights may illuminate, depending on the road conditions, etc.
Deceleration stop phase
After entering the deceleration stop phase, a buzzer will sound continuously and a message will be displayed to warn the driver, and the vehicle will slowly decelerate and stop. After the vehicle stops, the system will enter the stop and hold phase.
Stop hold phase
After the vehicle is stopped, the parking brake will be applied automatically. After entering the stop and hold phase, the buzzer will continue sounding continuously and the emergency flashers( hazard lights) will flash to warn other drivers of the emergency.
■ Restricted functions after the operation is canceled
After shifting to the deceleration stop phase, the following functions will not be available until the EV system is re-started even though the emergency driving stop system is
