Nissan has unveiled a navigated highway driving system with hands-off single-lane driving capabilities.

Expanding on the ProPilot system, the technology will debut on the Japanese-market Nissan Skyline in the autumn of 2019.

Designed for on-ramp to off-ramp (ramp-to-ramp) highway driving, the new system engages with the vehicle's navigation system to help manoeuvre the car according to a predefined route on designated roadways.1 For the first time, the system also enables hands-off driving while cruising in a single lane.

To enable the latest functions of the new system, drivers must first set their destination in the navigation system, creating a predefined travel route. Once the car enters the highway, the new system's navigated driving becomes available.

Upon activation using a predefined route, the system will assist the driver with travelling on a multi-lane highway until reaching the highway exit on a predefined route — helping to handle passing, lane diversions and lane exiting.

The new ProPilot also enables hands-off driving while cruising in a given lane. When the vehicle approaches a road divide, or when passing a slower vehicle is possible, the system judges the appropriate timing of branching off or passing based on information from the navigation system and 360-degree sensing.

Audio and visual guidance is given to the driver, who is prompted to put both hands on the steering wheel and confirm the start of these operations with a switch.

The vehicle uses a combination of cameras, radars, sonars, GPS and 3D high-definition map data (HD map) to provide 360-degree, real-time information of the surrounding environment and the vehicle's precise location on the road.

The system uses this information to provide a smooth driving experience, similar to that produced by an experienced driver. A monitoring system in the cabin continually confirms the driver's attention is on the road.
