Nissan ALTIMA 2022 Rear Automatic Braking (RAB) and Automatic Emergency Braking (AEB) 

The innovative Rear Automatic and Emergency Braking System, a crucial safety advancement intended to improve collision avoidance capabilities, is a component of the 2022 Nissan Altima. This system uses sophisticated rear-mounted sensors to identify objects and other cars behind the Altima. It then automatically applies the brakes in the case that it detects a possible rear-end collision, reducing or preventing accidents. The Rear Automatic and Emergency Braking System adds an additional layer of safety when reversing in tight spaces, navigating busy roads, or navigating parking lots. This lowers the risk of rear-end collisions and increases driver confidence and peace of mind.

AUTOMATIC EMERGENCY BRAKING (AEB) WITH PEDESTRIAN DETECTION

WARNING
Failure to follow the warnings and instructions for proper use of the AEB with the Pedestrian Detection system could result in serious injury or death. The AEB with Pedestrian Detection system is a supplemental aid to the driver. It is not a replacement for the driver’s attention to traffic conditions or responsibility to drive safely. It cannot prevent accidents due to carelessness or dangerous driving techniques. The AEB with Pedestrian Detection system does not function in all driving, traffic, weather, and road conditions. The AEB with Pedestrian Detection system can assist the driver when there is a risk of a forward collision with the vehicle ahead in the traveling lane or with a pedestrian ahead in the traveling lane.

The AEB with Pedestrian Detection system uses a radar sensor located on the front of the vehicle OB to measure the distance to the vehicle ahead in the same lane. For pedestrians, the AEB with Pedestrian Detection system uses a camera installed behind the windshield OA in addition to the radar sensor.

AEB WITH PEDESTRIAN DETECTION SYSTEM OPERATION.

1. The vehicle ahead detection indicator
2. AEB with Pedestrian Detection emergency warning indicator
3. AEB with Pedestrian Detection system warning light
4. The AEB system operates at speeds above approximately 3 mph (5 km/h). For the pedestrian detection function, the system operates at speeds between 6–37mph(10 – 60 km/h).
5. If a risk of a forward collision is detected, the AEB with Pedestrian Detection system will firstly provide the warning to the driver by flashing the vehicle ahead detection indicator (yellow) in the vehicle information display and providing an audible alert. If the driver applies the brakes quickly and forcefully after the warning, and the AEB with Pedestrian Detection system detects that there is still the possibility of a forward collision, the system will automatically increase the braking force.
6. If the driver does not take action, the AEB with Pedestrian Detection system issues the second visual (flashing) (red and white) and audible warning. If the driver releases the accelerator pedal, then the system applies partial braking. If the risk of a collision becomes imminent, the AEB with Pedestrian Detection system applies harder braking automatically.

While the AEB with Pedestrian Detection system is operating, you may hear the sound of brake operation. This is normal and indicates that the AEB with the Pedestrian Detection system is operating properly.

NOTE:
The vehicle’s brake lights come on when any braking is performed by the AEB with the Pedestrian Detection system. Depending on vehicle speed and distance to the vehicle or pedestrian ahead, as well as driving and roadway conditions, the system may help the driver avoid a forward collision or may help mitigate the consequences if a collision should be unavoidable. If the driver is handling the steering wheel, accelerating, or braking, the AEB with Pedestrian Detection system will function later or will not function.

The automatic braking will cease under the following conditions:

• When the steering wheel is turned to avoid a collision.
• When the accelerator pedal is depressed. When there is no longer a vehicle or a pedestrian detected ahead.

If the AEB with Pedestrian Detection system has stopped the vehicle, the vehicle will remain at a standstill for approximately 2 seconds before the brakes are released. For vehicles with a 7-inch (18 cm) display
