At the ongoing G7 Summit currently being held in Ise-shima, Japan, Nissan showcased its ProPILOT autonomous driving technology with a procession of prototype vehicles ferrying the various participants of the Summit.

The prototypes are based on the all-electric Nissan Leaf, which was fitted with special equipment, including a millimetre wave radar, laser scanners, cameras, and a specialised HMI (Human Machine Interface) to support the autonomous driving feature.

Each piece of equipment has to perform a specific function. For instance, the laser scanner determines the distance between the vehicle and its surroundings through precise three-dimensional measurements enabling navigation in tight spaces.

Meanwhile, the eight-way, 360-degree view camera system allows the car to make accurate routing decisions at intersections and on sharp curving roads. The technologies were tested on roads and highways in Japan and the United States earlier this year.

The ProPILOT system is set to be introduced in a Nissan model in Japan later this year. Availability will be later expanded to include Europe, United States and China. In its first iteration, ProPILOT 1.0 can be used in congested highway traffic conditions.

However, Nissan claims that by 2018, the system will be enhanced to include multi-lane, allowing the car to make highway lane changes. By 2020, the technology will allow the car to drive autonomously on urban roads, including intersections.
