EV driver acronyms index


A [unit] of measurement named after scientists must be capitalized to honor its inventor. The abbreviation of any unit in science should be in square brackets: [T], [N], [kWh] versus non-capitalized [sec]ond or [mi]le. Where is [T] stands for engineer-inventor Nicola Tesla, [A] - physicist André-Marie Ampère, [W] - inventor James Watt, and [N] - Sir Newton, Isaac - famous physicist.

SAE (J3016) Automation (AKA Autonomy) Levels
Tesla is the only production car that passed Automation Level 3 and almost all of Level 4 in 2020
SAE Level Automation Name Definition Who is driving Monitoring of driving environment
0 No Automation The automated system issues warnings and may momentarily intervene but has no sustained vehicle control Human Human driver
1 Driver Assistance Hands on: The driver and the automated system share control of the vehicle. Examples are systems where the driver controls steering and the automated system controls engine power to maintain a set speed (Cruise Control) or engine and brake power to maintain and vary speed (Adaptive Cruise Control or ACC); and Parking Assistance, where steering is automated while speed is under manual control. The driver must be ready to retake full control at any time. Lane Keeping Assistance (LKA) Type II is a further example of Level 1 self-driving. A automatic emergency braking which alerts the driver to a crash and permits full braking capacity is also a Level 1 feature, according to Autopilot Review magazine Human and system Human driver
2 Partial Hands off: The automated system takes full control of the vehicle: accelerating, braking, and steering. The driver must monitor the driving and be prepared to intervene immediately at any time if the automated system fails to respond properly. The shorthand "hands off" is not meant to be taken literally – contact between hand and wheel is often mandatory during SAE 2 driving, to confirm that the driver is ready to intervene. The eyes of the driver might be monitored by cameras to confirm that the driver is keeping their attention to traffic. SystemHuman driver
3 Conditional Eyes off: The driver can safely turn their attention away from the driving tasks, e.g. the driver can text or watch a movie. The vehicle will handle situations that call for an immediate response, like emergency braking. The driver must still be prepared to intervene within some limited time, specified by the manufacturer, when called upon by the vehicle to do so. You can think of the automated system as a co-driver that will alert you in an orderly fashion when it is your turn to drive. An example would be a Traffic Jam Chauffeur,[61] another example is the international Automated Lane Keeping System (ALKS) regulation System Human driver
4 High Mind off: As level 3, but no driver attention is ever required for safety, e.g. the driver may safely go to sleep or leave the driver's seat. Self-driving is supported only in limited spatial areas (geofenced) or under special circumstances. Outside of these areas or circumstances, the vehicle must be able to safely abort the trip, e.g. park the car, if the driver does not retake control. An example would be a robotic taxi or a robotic delivery service that only covers selected locations in a specific area. System System
5 Full Steering wheel optional: No human intervention is required at all. An example would be a robotic EV that works on all roads all over the world, all year around, in all weather conditions. System System
