Toyota Driver Monitoring System - Alerts Could Explain Erratic Behavior
It looks like Toyota was working on some driver assistance technology that may or may not have ever been implemented, but trying to gain a drivers attention by quickly applying and releasing the brakes indicates the possibility for this type of behavior to exist in the current brake problems.
The car’s safety system continuously monitors the road ahead using a radar system, and if it determines a crash may be possible, it matches this with the driver evaluation gathered from the camera. If the driver doesn’t appear to be paying attention it sounds a buzzer and warning light.
If things progress and a crash becomes probable then it also tries to gain attention of the driver by quickly applying and releasing the brakes. At this point the car’s pre-crash brake assist system is also readied. When a crash is judged to be unavoidable the safety system engages the brakes and seatbelts for the collision.
