In keeping to its promise of rolling out a more advanced version of auto pilot system the ProPILOT 1.0 Nissan launched in Yokohama, Japan in 2016, the company has unveiled Nissan ProPILOT 2.0.
1. Autonomy level of Nissan ProPILOT 2.0
While the ProPILOT 1.0 could perform standard functions like lane keeping, automatic braking and speed control with predefined speed limits, the ProPILOT 2.0 is even more advanced, performing more complex functions on the highway. The ProPILOT 2.0 performs both navigated and hands-free autonomous driving.
Nissan ProPILOT 2.0 will only be available for navigated driving in designated routes and highways. I do not have it in authority what Nissan’s autonomy level classification of the ProPILOT 2.0 is, but we at Naijauto believe the ProPILOT 2.0 looks more like an advance SAE level 2 autonomous system, incorporating some level 3 features thus acting like a bridge between the two levels.

The ProPILOT 2.0 performs both navigated and hands-free autonomous driving
The Nissan ProPILOT 2.0 offers hands free autonomous driving function when on a single lane expressway. As a level 3 autonomous system, the vehicle drives itself when all the conditions are met and in this case, when you enter a designated highway and predefined route. The system will perform driving functions like lane change and overtaking but will require the consent of the driver before executing such maneuvers.
The driver will be required to put his hands on the steering will to as prerequisite and a form of approval given to the system to continue with executing the maneuvers which the system has already determined to be safe to undertake. The implication of this is that the driver is still in control and must remain alert and supervise every operation.

Nissan says that the system will alert the driver when you enter a designated route, obviously through voice prompt and on-board display. When this prompt comes up, the driver has the option of initiating the system by pressing an integrated button on the steering wheel and when you get to the ramp-off, you can turn off the ProPILOT assist system using a button found same on the steering wheel with designated symbols.

2. How can Nissan ProPILOT 2.0 process data about real-time traffic?
To achieve success in performing these maneuvers safely and accurately, the system takes input from a variety of sources and carefully analyzes them before deciding if it is safe to perform such maneuver.
The system collects data from 3-dimensional HD map, radars, cameras and sonars strategically mounted at different positions all over the car to enhance the efficiency and effectiveness of the system. These inputs generate a 360 degree real-time data and information of the vehicle’s environment with very high precision. For instance, the sonars and radars, along with the cameras offers the system real time information like when another vehicle has entered the car’s Blind spot detection range, as well as the speed of the vehicle driving ahead.

Nissan claims that the ProPILOT 2.0 is the world’s first next generation assistance system and that it can perform lane change safely even without requiring the permission of the driver. But for regulatory restriction placed on this function, it will continue to require the driver’s permission before executing lane change.
3. Technical features tied to the ProPILOT 2.0
3.1. Three-Dimensional High Precision Map:
The Nissan ProPILOT 2.0 utilizes high definition and high precision GPS enabled digital maps for its operation. The map which is housed by the vehicle’s onboard computer data processing unit, are updated in real time over the air by the map data supply. The map data precision is so high that the ProPILOT can accurately calculate the current position of the car to within centimeters in Lateral direction and within meters in longitudinal direction as confirmed by Nissan’s General Manager for all things ADAS, Tetsuya Iijima.

3.2. Camera and Radar
The Nissan ProPILOT 2.0 is enhanced with 7 tri-focal cameras strategically positioned for utmost efficiency. The cameras are designed with wide angle lenses that have a wider view range. Also, ProPILOT 2.0 enabled cars have installed four short range radars.
Nissan will be rolling out the ProPILOT 2.0 before the end of the year and it will only be available to customers in Japan for now and will be made available to customers in US and across the globe with time. Nissan says it will first introduce the ProPILOT 2.0 in the Nissan Skyline. We envisage the ProPILOT 2.0 will be as successful as the ProPILOT 1.0, which accounted for about 350,000 ProPILOT enabled cars across the globe. As a sneak peek for our viewers, Nissan is currently building new battery technology for its electric cars and it plans to introduce this technology next year.
