FUNCTION DESCRIPTION
  • The system measures the distance from the vehicle ahead using the front camera unit and distance sensor, and allows for driving while keeping a proper distance, with the vehicle speed set by the driver as the upper limit speed. At the same time, it detects the lane markers of the lane which the vehicle is driving in and supports steering to keep the vehicle close to the center of the lane.
  • MI-PILOT Assist is composed of 2 functions: intelligent cruise control (ACC) and steering wheel assistance function.
 
 
Adaptive Cruise Control [ACC]
  • The Adaptive Cruise Control [ACC] system maintains a selected distance from the vehicle ahead within set speeds.
  • The driver can select the set speeds.
  • The vehicle travels at a set speed when the road ahead is clear.
  • The ACC system can be set to one of two cruise control modes:
    noteNever set the cruise speed exceeding the posted speed limit.
    • Vehicle-to-vehicle Distance Control Mode Function
      For maintaining a selected distance between own vehicle and the vehicle in front of own vehicle up to the preset speed. Refer to System Description.
    • Conventional (Fixed Speed) Cruise Control Mode Function
      For cruising at a preset speed. Refer to System Description.
 
 
Steering Wheel Assistance Function
The system detects the lane markers and supports steering to keep the vehicle close to the center of the driving lane. Refer to System Description.
 
 
EVENT DATA RECORDER (EDR)
 
 
Recording and Collecting Vehicle Data
MI-PILOT Assist system records and collects the following vehicle data.
  • Operating status of the accelerator pedal, brake pedal, steering wheel, and other controls
  • Detection status of vehicles ahead, lane markers, and other items
  • Vehicle speed and other vehicle information
  • Information related to MI-PILOT Assist operation
  • MI-PILOT Assist trouble diagnosis information
  • Front camera unit image information (when the SRS air bag or the forward emergency brake activates)
 
 
Handling of Data
  • Nissan Motor and third parties contracted by Nissan Motor may acquire and use data recorded in the event recorder for the purpose of improving Nissan Motor vehicle collision safety performance.
  • Nissan Motor and third parties contracted by Nissan Motor shall not disclose or provide the acquired data to any third party except in the following circumstances.
    • When the consent of the vehicle user is obtained
    • When based on a court order or other legally enforceable request
    • When the data is provided to a research institution or similar body after it is processed by statistical processing or other means so that it is not possible to identify the user or vehicle
noteThe recorded data cannot be acquired or used at a Nissan dealer.
