Nissan has launched all-new 2019 Nissan Altima which will be available with ProPILOT Assist. It is the third vehicle in Nissan’s U.S. lineup with ProPilot Assist.
ProPILOT Assist is a key component of Nissan Intelligent Mobility, the company’s vision for changing how cars are powered, driven and integrated into society and sets the foundation for the autonomous vehicles of the future.
ProPILOT Assist eases driver workload by reducing the amount of driver acceleration, steering, and braking input under certain driving conditions. To activate the system, the driver simply pushes the blue ProPILOT Assist ON button, which is integrated into the right-side steering wheel spoke. Step two is to set the Intelligent Cruise Control when the desired speed is reached, as with a normal advanced cruise control system.
When lane markers are consistently detected, steering assist engages and the steering wheel/lane marker icons on the instrument panel turn green. Both right and left-hand markers need to be detected by the front camera. Steering assist will engage or disengage depending on the visibility or presence of lane markers, though the Intelligent Cruise Control will remain active.
If the vehicle comes to a complete stop in a traffic jam situation for more than three seconds, the driver just presses the resume button or taps the accelerator pedal to begin moving again.
ProPILOT Assist uses a forward-facing camera, forward-facing radar, sensors and electronic control module to help the driver stay in the center of the driving lane and to maintain vehicle speed (set by the driver) or help maintain a gap to the preceding vehicle if the vehicle speed drops below the driver-set speed. It also can slow the vehicle to a complete stop and holds the vehicle during traffic jam conditions.
While providing steering assist, reducing the need for constant small steering adjustments, the driver’s hands must be on the steering wheel at all times. Hands-on detection is provided by the system’s steering torque sensor. If the driver only grips the steering system with a light touch, the warning system may activate, alerting the driver to apply more pressure or a tighter grip on the steering wheel.
Steering assist is canceled in inclement weather if the windshield wipers are in the low or high position (if lane lines can be detected, the system can remain active when the wipers are in the intermittent mode or if the mist function is activated).
The driver’s input always takes priority, overriding the system when the steering wheel is turned or the turn signal is operated (steering assistance goes into a temporary standby mode). The system also goes into temporary standby mode when the accelerator pedal is pressed. And, the system’s Intelligent Cruise Control and lane keep assistance are both canceled when the brakes are applied.
