- This is my experimental branch, so I'm not responsible for any damage this may cause.
- jvePilot still does not have direct control of the gas and brakes! Changing the ACC speed does not always result in the vehicle braking unless the difference in speed is large enough. If the speed difference is small, the vehicle just lets off the gas.
- ACC can't go slower that 20mph
- ACC doesn't do a good job at seeing things that are already stopped
I have a 2018 Grand Cherokee Trailhawk, so I'm only able to confirm features using this vehicle.
- Pacifica also confirmed to be working
This is my personal OpenPilot fork that includes features that I feel make it a better driving experience for me and possibly others.
- Smother driving in traffic as jvePilot will do a better job at predicting traffic and adjust ACC speed accordingly
- ACC braking by setting the cruse speed lower that the target to help slow the vehicle sooner
- Slow for cars cutting in before ACC does
- Slow in a turn, so you don't have to change the set speed yourself (Speeds are configurable)
- Always On Lateral Control so steering is active even if ACC isn't
- Auto enable ACC on start
- Auto follow feature to adjust the follow distance based on speed (Speeds are configurable)
- ACC Eco to limit the throttle when accelerating
- Syncs jvePilot display speed with the vehicle speedometer
- Gas/brake indication using green/red colors on speed indicator
This fork combines the speed control logic of OpenPilot with the vehicles Adaptive Cruse Control (ACC). It does this by changing the ACC speed to match the value OpenPilot calculates as the desired speed. This brings some of OpenPilots longitudinal control to these vehicles. Including things like slowing while cornering and slowing when it detects cut-ins. It will also smooth the braking of ACC when driving in traffic.
On FCA vehicles, only the steering is controlled by jvePilot and speed is left up to the ACC of the vehicle. This fork takes control of the ACC speed setting and adjusts the ACC speed to match the speed jvePilot would be targeting if it actually was able to control the gas and brakes. It does this by simulating ACC+ and ACC- button presses on the steering wheel to change the ACC speed. It is limited as ACC only goes down to 20 mph, so it doesn't help as low speeds.
Always On Lateral Control, or AOLC, is a feature that allows jvePilot to steer even if ACC isn't actively engaged. Enabling this feature will allow a driver to take control of gas/brakes while still retaining the automatic steering provided by jvePilot. Because the low torque applied to the steering, it's very easy to override the steering if needed.
When enabled, jvePilot will enable ACC on start. This pairs well with Always On Lateral Control so lateral control is ready to go without having to remember to press the ACC on/off button.
Auto Follow is a way to automate the changing of the stock follow distance setting. It sets the follow distance to closer at slow speeds and increases it the faster you go. Setting the follow speed to one/two bars helps with keeping up with cars that take off when stopped or at slow speeds. The faster you go, the more distance you want, so you can have more confidence in ACC being able to stop in case it needs to.
The current enabled state of Auto Follow is as an icon above the ACC Eco button on the jvePilot display. Pressing Follow + or - will disable Auto Follow giving you full control to set the follow distance. To re-enable Auto Follow, hold either Follow + or - for half a second.
When enabled, jvePilot will limit how far ahead the ACC setting is above the current speed. This prevents the vehicle from using an aggressive throttle to get up to speed saving on gas/battery.
The ACC Eco button is located in the lower right corner of the display. Tapping the button cycles between off, level 1, and level 2 eco settings. Level 2 provides the slowest acceleration and is selected when both leaves are green. Level 1 should provide a balance is selected when only one leaf is green. If you feel these settings are not right for you or your vehicle, see the ACC Eco setting to adjust them. Much like your vehicles eco/sport modes, the current setting is persisted between drives.
When using this branch, you will be setting the max ACC speed on the jvePilot display instead of the one in the dashboard. jvePilot will then set the ACC setting in the dashboard to the targeted speed, but never exceeding the max speed set on the jvePilot display. A quick press of the ACC+ and ACC- buttons will change this speed by 5 mph on the jvePilot display, while a long deliberate press (about a 1/2 second press) changes it by 1 mph. DO NOT hold the ACC+ or ACC- buttons for longer that a 1 second. Either make quick or long deliberate presses only.
Do not look at the dashboard when setting your ACC max speed. Instead, only look at the one on the jvePilot display. The reason you need to look at jvePilot is because jvePilot will be changing the one in the dashboard. It will be adjusting it as needed, never raising it above the one set on the jvePilot display.
ONLY look at the MAX speed on jvePilot when setting the ACC speed instead of the dashboard!
The easiest way to install jvePilot is to factory reset your C3 and use this Custom Software URL: https://bit.ly/jvePilot-release
/jvePilot-release - The latest release. Will contain the latest version I feel is ready for daily use. Custom Software URL: https://bit.ly/jvePilot-release
/jvePilot-beta - Sometimes I have people wanting to beta test jvePilot's new features. Mostly stable, but still can be buggy. Custom Software URL: https://bit.ly/jvePilot-beta
/feature/* - These branches are where I'm working on new features. These are never safe to run as they change all the time.
Customizing features and parameters can be done on the UI display. Click the gear icon and then select jvePilot from the sidebar. Clicking on the text of feature of will show more information about it and allow customization of the feature. Note that some settings do require a vehicle restart, and some don't The settings that don't require a restart may take upward of 5 seconds to take effect after changing them.
jvePilot will slow in curves so that you don't have to.
- Default: On
- Vehicle Restart Required: No
Use this to tune the speed in curves to you liking. Setting this to 1.2 will cause jvePilot to drive 20% faster in turns than if it was set to the default of 1.0
- Default: 1.0
- Units: Ratio
- Vehicle Restart Required: No
- Min/Max values (0.1, 2)
Adjusts how much the speed drops as the curve increases. Decrease this value to lessen the amount of drop off as the curve increases. Changing this value will likely require adjusting the Speed Ratio to compensate.
- Default: 2.0
- Vehicle Restart Required: No
- Min/Max values (1.0, 3.0)
Reverse the stock ACC +/- button's 1mph on short press and 5mph on long press. Turn off to return to stock style.
- Default: On
- Vehicle Restart Required: Yes
If you don't want auto follow enabled on every start, turn this off.
When your speed (in MPH) is below this setting, Auto Follow will set the follow setting to one bar. When you reach this speed (in MPH), Auto Follow will set the follow setting to two bars.
- Default: 15
- Units: MPH
- Vehicle Restart Required: No
- Min/Max values (0, 300)
When your speed (in MPH) is below this setting, Auto Follow will set the follow setting to two bars. When you reach this speed (in MPH), Auto Follow will set the follow setting to three bars.
- Default: 30
- Units: MPH
- Vehicle Restart Required: No
- Min/Max values (0, 300)
When your speed (in MPH) is below this setting, Auto Follow will set the follow setting to three bars. When you reach this speed (in MPH), Auto Follow will set the follow setting to four bars.
- Default: 65
- Units: MPH
- Vehicle Restart Required: No
- Min/Max values (0, 300)
ACC Eco limits acceleration by keep the ACC cruise speed closer to your current speed. These setting are how far ahead, in MPH, of your current speed ACC will be set. The higher the number, the more aggressive ACC will be when accelerating.
Use this setting to adjust ACC Eco level 1 (one green leaf) for a balance of speed and eco-ness
- Default: 7
- Units: MPH
- Vehicle Restart Required: No
- Min/Max values 1, 100
Use this setting to adjust ACC Eco level 2 (two green leaves) for maximum eco-ness

- Min/Max values 1, 100
When this is enabled, you will hear a chime when your vehicle drops to a certain speed and can no longer be steered.
- Default: On
- Vehicle Restart Required: No
Compensate for mounting your device off center in the windshield. If you mounted your device off center, use this setting to compensate. Use positive values if your device is to the left of center and negative if it's to the right.
- Default: 0
- Units: Meters
- Vehicle Restart Required: No
- Min/Max values -1, 1
These settings are for advanced users doing advanced things.
When disabled, jvePilot will no longer put a minimum on steer speed.
