THE TECHNOLOGY BEHIND IT
In order to keep track of lane markings and your car’s location within your lane, this feature utilizes some of the sensors from lane departure warning systems. Many drowsiness alert feature versions will monitor how frequently you stray from your lane over a brief period of time to assess whether you could be drowsy.
Advanced models are able to “learn what your typical driving habits are when you are not tired.” The system may warn you to take a break from driving if you start driving in an unexpected way, such as making a lot of abrupt movements or stops.
WHAT YOU NEED TO DO
Look, hear, and feel for indications from your drowsiness alert system that you may have started to nod off while operating a vehicle.
- If it believes you are drowsy, drowsiness alert systems display a coffee cup on your dashboard and a message urging you to take a break from driving.
- Some systems that have audio alerts may advise you to take a break as soon as it’s safe to do so if you feel like you might be getting sleepy.
- In some vehicles with drowsiness warnings, your seat may vibrate.
TIPS FOR USING
- Drowsiness warnings are intended to inform you that you have started driving while drowsy; if you are aware of your drowsiness, you shouldn’t start driving in the first place.
- Plan periodic driving breaks every two hours or so during long journeys to lessen the chance of falling asleep behind the wheel. Take turns if you’re driving with other licensed drivers.
- Select a secure spot for your break. Using the built-in GPS, some automobiles with drowsiness alerts may automatically warn you to rest stops nearby.
How do vehicles recognize sleepiness?
The algorithm used for the driver sleepiness detection starts monitoring the driver’s steering behavior as soon as the journey starts. It then detects changes over the course of lengthy journeys and, as a result, the degree of driver tiredness. Phases when the driver is hardly steering are typical indicators of fading focus, as are slight, rapid, and sudden steering movements to maintain the automobile on the road.
The function determines the driver’s level of exhaustion based on the frequency of these movements as well as other factors, such as the distance traveled, the use of turn signals, and the time of day. An icon, such as a coffee cup, flashes on the instrument panel to alert drivers that they should take a break if that level rises above a specified threshold.

For even more peace of mind when driving, Lexus models equipped with Steering Assist gently push the steering wheel in the event of an impending lane departure, and Lane Keeping Assist aids to maintain location when the car is in Dynamic Radar Cruise Control.
When a brief slip of concentration could be dangerous, these LDA features aid in preventing mishaps brought on by fatigue or loss of focus. Drivers can maintain their composure and confidence before starting their journey thanks to LDA notifications.

Why does the backseat of my car need to be checked for all items?
Eight Nissan cars will get the rear-door warning system for the 2019 model year, and by the 2022 model year, all of the company’s four-door models will have it.
The system was created by Nissan engineers Elsa Foley and Marlene Mendoza. After leaving a pan of lasagna in her car’s back seat for the night, Mendoza had the inspiration.
She remarked, “You know when they give you leftovers in an aluminum pan?” “My entire car smelled like lasagna the next day.”
Mendoza and Foley created the unique technique while they were new mothers residing in Nashville. They expect the system to contribute to children’s safety.
We would hear about situations where parents unintentionally left a child in the car, and Mendoza said he always worried it might happen to him. So we started thinking creatively, and that’s how we developed the concept.
The technology keeps track of rear-door usage and reminds the driver to check the back seat after their excursion is over. The process begins with the text message “Check rear seat for all items” on the dashboard. Next, there are “subtle yet unmistakable chirps of the horn,” according to Nissan.
Dealers provide customers with the opportunity to activate the system when they purchase a Nissan. Later, drivers can either temporarily or permanently deactivate the system.
However, that might not be a wise move. Nissan issued a warning that a car’s interior can reach temperatures of more than 110 degrees even when the outside temperature is less than 70 degrees.
What is object alert for the backseat?
Rear Occupant Alarm (ROA) is an automatic vehicle alert system developed by automobile manufacturer Hyundai Motor Company to identify the presence of a passenger in the back seat of a motor vehicle.

[3] Ultrasonic sensors are also used by a more advanced system known as Ultrasonic Rear Occupant Alert. [2] The system will flash the hazards lights and sound the horn for 25 seconds if the vehicle is locked and the ultrasonic sensors on the headlining detect movement in the back seats. If the system continues to detect movement, the system may flash the lights and sound the horn up to eight times in total. [3]
Rear Seat Reminder from General Motors, Rear Door Alert from Nissan, and Rear Seat Reminder from Subaru are a few other manufacturers’ systems.

A proposed law in the US would require such a system in all passenger vehicles.

Driver Attention Monitor
The Driver Attention Monitor continuously observes and evaluates motorist behavior on highways and arterial routes to help identify when a driver is starting to become inattentive and, if so, alert the driver to take a break. The system uses information from the Electric Power Steering (EPS) to calculate four gradients that represent the frequency and seriousness of the driver’s steering inputs.
On the MID, below the speedometer and tachometer, a coffee cup icon and a 4-level bar graph warn the driver when the Driver Attention Monitor is turned on. The bar graph shows complete focus with four white bar parts that are lit up. The number of lit bars decreases as the driver’s concentration wanes. A message encouraging the motorist to stop is flashed when there are only two bars remaining. In order to remind the driver to pay closer attention or take a break, a beeper sounds and the steering wheel vibrates if the graph dips below the lowest level of one bar while they are still driving.
