Name Description Popularity
Adaptive Headlights Adapts to changing roadway conditions - such as curves - to better help illuminate the roadway along your path. 17
Brake Assist Adds additional braking power to your car during emergency stops.Drivers' reaction times don't always match how quickly they need to react to avoid a crash. If electronic braking assistance notices drivers slamming the brake pedal, it applies maximum force to the brakes to help make sure the car stops as quickly as possible. Make sure to keep a safe following distance from vehicles ahead of you as you drive. 15
Auto Resume After Stop After vehicle comes to a stop in traffic, the vehicle will automatically begin driving again after any length of time. 6
Backup Warning Alerts you of objects behind your car as you back out of spaces like driveways or parking spots. 13
Temperature Warning Alerts you when the outside temperature is detected to be at or below freezing, which can impact the conditions of roadways.This recently introduced feature uses temperature readings and other information to help warn drivers when roads are or may become icy. 10
High Speed Alert An alert that sounds if you're speeding.This feature coordinates the car's position, via GPS, with a database of speed limit information to alert drivers if they're speeding. This helps drivers maintain a safe driving speed. Newer versions may use a camera to read speed limit signs.A more advanced version of this feature, called intelligent speed adaptation, would be capable of slowing down the car automatically if a driver passes the speed limit. Drivers would be able to override most versions of intelligent speed adaptation. This feature currently is being researched in Europe and the United States, among other countries. 5
Antilock Braking System Anti-lock braking systems (ABS) help you steer in emergencies by restoring traction to your tires. 31
Backup Camera Back-up cameras help you see objects directly behind you while backing. Remember to always look over your shoulder and in your mirrors as you back up. 19
Obstacle Detection Can sense slow-moving or stationary objects when driving at low speeds. Some may even brake for you to avoid obstacles. This feature activates at slow speeds and will provide warnings of impending collisions. For some versions, it will brake the car automatically. 11
No Drive-by-wire Steering Control Below Speed Due to a restriction with the factory EPS (Electronic Power Steering) system, openpilot is unable to control steering below a certain speed. 54
Electronic Brakeforce Distribution Electronic brakeforce distribution (EBD or EBFD) or electronic brakeforce limitation (EBL) is an automobile brake technology that automatically varies the amount of force applied to each of a vehicle's wheels, based on road conditions, speed, loading, etc. Always coupled with anti-lock braking systems (ABS), EBD can apply more or less braking pressure to each wheel in order to maximize stopping power whilst maintaining vehicular control.[1][2] Typically, the front end carries the most weight and EBD distributes less braking pressure to the rear brakes so the rear brakes do not lock up and cause a skid.[3] In some systems, EBD distributes more braking pressure at the rear brakes during initial brake application before the effects of weight transfer become apparent. 7
Automatic Parallel Parking Helps guide you into a parallel parking spot after searching and finding a viable option. You still are responsible for braking and monitoring your environment. 5
Hill Descent Assist Helps keep you at a steady speed when driving down a hill or other decline. 11
Electronic Stability Control Helps prevent loss of control in curves and emergency steering maneuvers by stabilizing your car when it begins to veer off your intended path. 14
Hill Start Assist Helps prevent roll-back when starting up again from a stopped position on an incline. 10
Requires Driver Steering Wheel Torque If the driver does not apply torque to the steering wheel after a specific time, the vehicle will disengage autonomy features. 51
Lane Departure Warning Lane departure warning systems alert you if you're drifting out of your lane using visual, vibration or sound warnings. 15
Openpilot Direct Longitudinal Control Openpilot is used to control braking and acceleration. 8
Openpilot Direct Lateral Control Openpilot is used to control left and right movements directly. 11
Openpilot Indirect Longitudinal Control Openpilot uses the factory adaptive cruise control. Sometimes this is done for technical reasons, other times the factory system is just better. 6
Sideview Camera Shows you an expanded view of a lane beside you when you use your turn signal, or when you activate the feature manually.This feature shares similar uses to blind spot monitors. 3
Blind Spot Monitor These monitors warn you of cars driving in your blind spots. They may provide an additional warning if you use your turn signal when there is a car next to you in another lane. 15
Forward Collision Warnings The vehicle alerts the driver of potential immanent collisions. 16
Speed Limit Warnings The vehicle alerts the driver when speed exceeds limit of roadway. 4
Automatic High Beam Headlights The vehicle automatically turns on high beam headlights. 15
Tactically Maneuvers Urban / City Streets / Roundabouts The vehicle can automatically handle sharp turns, and various urban driving. Very unlikely. 3
Stop Sign Detection The vehicle detects stop signs and optionally takes action accordingly. 2
Street Light Detection The vehicle detects street lights and optionally takes action accordingly. 3
Speed Limit Sign Detection The vehicle detects the speed limit by looking for posted signs and optionally takes action accordingly. 3
Lane Keeping Assist (LKAS) - Basic The vehicle follows a set path given there are at least 1 lane lines being tracked. May gently steer you back into your lane if you begin to drift out of it. This is generally the factory installed system on the vehicle, more advanced systems exist in varying car makes so you may want to use Intermediate or Advanced depending on the manufacturers features LKAS 53
Automatic Lane Change The vehicle is capable of changing lanes for optimal speed, safety, and navigation. 3
Radar Assisted ACC The vehicle is equipped with a radar to track objects. 57
Minimum Speed To Engage The vehicle is required to be driven above a certain speed to engage LKAS and ACC features. 66
OTA Updates The vehicle receives updates to its model and/or hd maps when connected to WiFi and/or LTE. 10
HD Map Assisted Localization The vehicle uses advanced 3D mapping data generated by a third-party to give the computer vision 4
Lidar Assisted Control The vehicle uses advanced lidar devices to track objects. Very unlikely to be factory installed. 3
Vision-only Assisted ACC The vehicle uses cameras to track objects and is not equipped with a radar. 5
Brakes Down To Zero The vehicle will brake down to zero. 16
Openpilot Driver Monitoring The vehicle will monitor your attention visually based on your head position. 9
Automatic Emergency Braking This feature can sense slow or stopped traffic ahead and urgently apply the brakes if the driver fails to respond. AKA Collision Mitigation System 16
Drowsiness Alert This feature may alert you if you're drowsy and suggest you take a break when it's safe to do so. 7
Left Turn Crash Avoidance This feature monitors traffic when the driver turns left across traffic at low speeds (such as at a traffic light). The car will automatically brake if it detects that you're turning in front of a car. 4
Bicycle Detection This is a warning feature that alerts drivers when a bicycle has been detected. Some systems can only detect bicyclists when traveling directly in front of the vehicle and when moving in the same direction. 7
Lane Keeping Assist (LKAS) - Advanced This is generally reserved for HD Map Assisted tech, similar to Cadillac SuperCruise and configurations running future versions of Openpilot. LKAS 15
Requires Manual Resume When Stopped This vehicle's factory ECU cancels LKAS / ACC features when the vehicle is stopped for a period of time. 5
Tire Pressure Monitoring System Tire pressure monitoring systems (TPMS) may warn you if your tires are under- or over-inflated, helping increase your fuel economy and even potentially preventing a tire blowout. 13
Pedestrian Detection Uses advanced sensors to detect human movements; some versions may urgently apply the brakes if the driver fails to respond. 6
Rear Cross Traffic Alert Warns you if one or more vehicles are about to enter your backing path. 6
Curve Speed Warning Warns you when you're approaching a curve or exit on the road too quickly.Drivers may not always remember to reduce their speed when taking an exit. Or, if it's late at night or the driver is unfamiliar with the area, they may not realize they're about to enter a curve. This feature tracks the car's speed and location, via GPS, and warns the driver to slow down when approaching curves and exits.Some versions of this feature can coordinate with a database of high-risk curves and exits to alert drivers to take extra caution. 4
Traction Control Works in the background to help accelerate and prevent wheel slippage (or over-spinning”) when driving on slippery surfaces.Traction control is most effective when accelerating from a stopped or slowed position, or when trying to accelerate up a slippery hill. This feature provides a lot of benefits to drivers, from making driving smoother to helping them stay in control of the car on icy roads or during rainy weather.Drivers should be sure to reduce their speed and take turns more slowly when driving in slippery conditions. 14
