Nissan is the first Japanese automaker to introduce a combination of steering, accelerator and braking that can be operated in full automatic mode, easing driver workload in heavy highway traffic and long commutes.
Employing image-processing technology, the car’s ProPILOT system understands road and traffic situations and executes precision steering enabling the vehicle to perform naturally. The ProPILOT technology activated and deactivated by the driver using a switch on the steering wheel. ProPILOT’s fit-to-drive interface includes a personal display showing the operating status. The accelerator, brakes and steering are controlled based on information obtained through a mono camera equipped with advanced-image processing software. The ProPILOT camera can recognise in three-dimensional depth both preceding vehicles and lane markers.
Once activated, ProPILOT automatically controls the distance between the vehicle and the preceding vehicle, using a speed preset by the driver (between approximately 30 km/h and 100 km/h). The system also keeps the car in the middle of the highway lane by reading lane markers and controlling steering, even through curves.
If a car in front stops, the ProPILOT system automatically applies the brakes to bring the vehicle to a full stop. After coming to a full stop, the vehicle will remain in place even if the driver’s foot is off the brake pedal. When ready to resume driving, ProPILOT is activated when the driver touches the switch again or lightly presses the accelerator.
Nissan says that intensive studies are being carried out of driving conditions in various regions so that ProPILOT will be well suited to the conditions in the markets in which it will be launched. The ProPILOT system equipped on the Serena in Japan was developed in pursuit of an easy-to-use technology for highway driving conditions in the country.
ProPILOT will be introduced into other vehicles, including the Qashqai in Europe in 2017. There are also plans for the technology to be introduced in the U.S. and China markets. A multi-lane autonomous driving technology will enable automatic lane changes on highways and is planned for introduction in 2018 while autonomous driving on urban roads and in intersections is planned for launch in 2020.
