Subaru eyesight was first available in the following years/models and includes the following features:
 
* Pre-Collision Warning, Braking, and Throttle Management (Throttle lift-off during emergency braking)
 
* Lane Departure Warning
 
* Adaptive Cruise Control
 
* Dual cameras instead of radar
 
  
''Gen1 of Eyesight only featured 'notification' systems to alert the driver of lane departure/braking events; Gen2 allows emergency braking at any time. Gen3 includes the LKAS after lane departure and ACC restart after full stops.''

Main requirements for adding Openpilot support are Eyesight and LKAS. Adding Openpilot support to models not listed means adding a new fingerprint.

Openpilot handles steering using EON, Panda and Giraffe or custom wire harness.

== Longitudinal control (accelerator and brakes) ==
 +
 
 +
Eyesight handles longitudinal control using stock ACC. Stop and go support - stop is automatic, go requires ACC resume button

Main requirements for adding Openpilot support are Eyesight and LKAS. Adding Openpilot support to models not listed means adding a new fingerprint.

Installation

Lateral control (steering)

Openpilot handles steering using EON, Panda and Giraffe or custom wire harness.

Longitudinal control (accelerator and brakes)

Eyesight handles longitudinal control using stock ACC. Stop and go support - stop is automatic, go requires ACC resume button

Overview

Subaru eyesight was first available in the following years/models and includes the following features:

  • Pre-Collision Warning, Braking, and Throttle Management (Throttle lift-off during emergency braking)
  • Lane Departure Warning
  • Adaptive Cruise Control
  • Dual cameras instead of radar

Gen1 of Eyesight only featured 'notification' systems to alert the driver of lane departure/braking events; Gen2 allows emergency braking at any time. Gen3 includes color cameras, LKAS(2016+) after lane departure and ACC restart after full stops.

Gen2 - 2014 Forester Touring, Legacy

  • Pre-Collision Warning, Braking, and Throttle Management (Throttle lift-off during emergency braking)
  • LDW
  • ACC
  • Stereoscopic cameras


Gen3 (CVT) - 2015 Legacy, Outback, Crosstrek

  • ACC - Adaptive cruise control
  • Constant speed cruise control
  • Pre-collision braking
  • AT rapid start prevention control
  • Lane departure warning
  • Sway warning
  • Preceding vehicle start monitoring function


Gen3 - 2016+ Legacy, Outback, Impreza,

  • LKAS - Active lane keep (lane departure prevention)
  • ACC - Adaptive cruise control
  • Constant speed cruise control
  • Pre-collision braking
  • AT rapid start prevention control
  • Lane departure warning
  • Sway warning
  • Preceding vehicle start monitoring function

Optional extras:

  • BSD - blind spot detection (2 radars with 75 degree FOV in rear corners)
    • LCA - lane change assistance
    • RCTA - reversing assistance
  • RAB (reverse assisted braking, 4 sonar sensors in rear bumper)

More information can be found here

Main CAN bus wiring harness

CAN messages are filtered by CAN gateway (Body Integrated Unit) on the global platform and MY18+ cars. Getting unfiltered CAN messages requires direct connection to main CAN bus. Here are two possible options for directly connecting to CAN bus:

A-pillar

Eyesight compartment

Removing Eyesight cover
