🚨 Read Before Installing 🚨

It is recommended to read this entire page before proceeding. This will ensure that you fully understand each added feature on this fork and you are selecting the right branch for your car to have the best driving experience.

This fork is recommended to be used for Hyundai/Kia/Genesis (HKG), Honda, Toyota, and Subaru cars. It is a fork of comma.ai's openpilot. By installing this software, you accept all responsibility for anything that might occur while you use it. All contributors to this fork are not liable. Use at your own risk.

🚗 Highlight Features

Driving Enhancement

• Modified Assistive Driving Safety (MADS) - sunnypilot Automatic Lane Centering (ALC) and Adaptive Cruise Control (ACC) / Smart Cruise Control (SCC) can be engaged independently of each other
  • This feature is enabled by default and can be disabled in the "sunnypilot" menu
• Dynamic Lane Profile (DLP) - Dynamically switch lane profile base on lane recognition confidence

• Stand Still Timer - Display time spent at a stop with M.A.D.S engaged (i.e., at a stop lights, stop signs, traffic congestions)
• Braking Status - Current car speed text turns red when the car is braking by the driver or ACC/SCC

Operational Enhancement

• Fast Boot - sunnypilot will fast boot by creating a Prebuilt file
• Disable Onroad Uploads - Disable uploads completely when onroad. Necessary to avoid high data usage when connected to Wi-Fi hotspot
• Brightness Control (Global) - Manually adjusts the global brightness of the screen
• Driving Screen Off Timer - Turn off the device screen or reduce brightness to protect the screen after car starts
• Driving Screen Off Brightness (%) - When using the Driving Screen Off feature, the brightness is reduced according to the automatic brightness ratio
• Max Time Offroad - Device is automatically turned off after a set time when the engine is turned off (off-road) after driving (on-road)

🚗 Driving Enhancement

Modified Assistive Driving Safety (MADS)

The goal of Modified Assistive Driving Safety (MADS) is to enhance the user driving experience with modified behaviors of driving assist engagements. This feature complies with comma.ai's safety rules as accurately as possible with the following changes:

• sunnypilot Automatic Lane Centering and ACC/SCC can be engaged independently of each other
• Dedicated button to toggle sunnypilot ALC:
  • LFA button: Newer HKG cars with LFA butotn
  • LKAS button: Honda, Toyota, Global Subaru
  • CRUISE (MAIN) button: HKG cars without LFA button, Pre-Global Subaru
• SET- button enables ACC/SCC
• CANCEL button only disables ACC/SCC
• CRUISE (MAIN) must be ON to use MADS and ACC/SCC
• CRUISE (MAIN) button disables sunnypilot completely when OFF (strictly enforced in panda safety code)
• BRAKE pedal press will pause sunnypilot Automatic Lane Centering; BRAKE pedal release will resume sunnypilot Automatic Lane Centering; BRAKE pedal release will NOT resume ACC/SCC without an explicit entry
• GAS pedal press will not disengage sunnypilot Automatic Lane Centering or ACC/SCC
• TURN SIGNALS (Left or Right) will pause sunnypilot Automatic Lane Centering if the vehicle speed is below the threshold for sunnypilot Automatic Lane Change
• Event audible alerts are more relaxed to match manufacturer's stock behavior

Dynamic Lane Profile (DLP)

Dynamic Lane Profile (DLP) aims to provide the best driving experience with staying within the lane confidently. Dynamic Lane Profile allows sunnypilot to dynamically switch between lane profiles base on lane recognition confidence level on road.

There are 3 modes to select on the onroad camera screen:

• Auto Lane: sunnypilot dynamically chooses between Laneline or Laneless model
• Laneline: sunnypilot uses Laneline model only.
• Laneless: sunnypilot uses Laneless model only.

To use Dynamic Lane Profile, do the following:

1. sunnypilot Settings -> Toggles -> Disable use of lanelines -> ON toggle
2. Reboot.
3. Before driving, on the onroad camera screen, toggle between the 3 modes by pressing on the button.
4. Drive. 

Enhanced Speed Control

This fork now allows supported cars to dynamically adjust the longitudinal plan based on the fetched map data. Big thanks to the Move Fast team for the amazing implementation!

Supported cars:

• sunnypilot Longitudinal Control capable
• Stock Longitudinal Control
  • Hyundai/Kia/Genesis
  • Honda Bosch
  • Volkswagen MQB

Certain features are only available with an active data connection, via:

• comma Prime - Intuitive service provided directly by comma, or;
• Personal Hotspot - From your mobile device, or a dedicated hotspot from a cellular carrier.

Features:

• Vision-based Turn Speed Control (VTSC) - Use vision path predictions to estimate the appropriate speed to drive through turns ahead - i.e., slowing down for curves
• Map-Data-based Turn Speed Control (MTSC) - Use curvature information from map data to define speed limits to take turns ahead - i.e., slowing down for curves
  • Note: Require data connection
• Speed Limit Control (SLC) - Use speed limit signs information from map data and car interface to automatically adapt cruise speed to road limits
  • HKG only: Highway Driving Assist (HDA) status integration - on applicable HKG cars only
  • Note: Require data connection
    • Speed Limit Offset - When Speed Limit Control is enabled, set speed limit slightly higher than the actual speed limit for a more natural drive
      • Note: Require data connection
• Hands on Wheel Monitoring - Monitor and alert when driver is not keeping the hands on the steering wheel

Instruction

📗 How to use Custom Longitudinal Control on sunnypilot 📗

When using Speed Limit Control, Vision or Map based Turn control, you will be setting the "MAX" ACC speed on the sunnypilot display instead of the one in the dashboard. The car will then set the ACC setting in the dashboard to the targeted speed, but never exceeding the max speed set on the sunnypilot display. A quick press of the RES+ or SET- buttons will change this speed by 5 MPH or KM/H on the sunnypilot display, while a long deliberate press (about a 1/2 second press) changes it by 1 MPH or KM/H. DO NOT hold the RES+ or SET- buttons for longer that a 1 second. Either make quick or long deliberate presses only.

‼ Where to look when setting ACC speed ‼

Do not look at the dashboard when setting your ACC max speed. Instead, only look at the one on the sunnypilot display, "MAX". The reason you need to look at the sunnypilot display is because sunnypilot will be changing the one in the dashboard. It will be adjusting it as needed, never raising it above the one set on the sunnypilot display. ONLY look at the MAX speed on the sunnypilot display when setting the ACC speed instead of the dashboard!
