Tesla Autopilot, an advanced driver-assistance system for Tesla vehicles, uses a suite of sensors and an onboard computer. It has undergone several hardware changes and versions since 2014, most notably moving to an all-camera-based system by 2023, in contrast with ADAS from other companies, which include radar and sometimes lidar sensors.
For instance, highway chauffeur is a Level 3 system, and automated valet parking is a level 4 system, both of which are not in full commercial use in 2019. [8] The levels can be roughly understood as Level 0 - no automation; Level 1 - hands on/shared control; Level 2 - hands off; Level 3 - eyes off; Level 4 - mind off, and Level 5 - steering ...
1991–2010 4T60-E/4T65-E/4T65E-HD — 4-speed medium-duty (used in larger front wheel drive GM vehicles) 1993–2010 4T80-E — 4-speed heavy-duty (used in large FWD GM vehicles, only with Cadillac NorthStar V8 and Related Oldsmobile V8)
The speed values in this table are produced from the formula using an "average" coefficient of friction (μ) of 0.7, and a perception-reaction time of 1.5 seconds. Speed values specific to a given circumstance can be obtained with the same formula using the appropriate reference constants specific to the circumstance.
For example, in Generation 1 and Generation 2 HSDs maximum speed is mainly limited by the speed of the smaller electric motor (often functioning as a generator). The Generation 3 HSD separates the ICE-MG1 path from the MG2 path, each with its own, tailored gear ratio (1.1:1 and 2.5:1, respectively, for late Priuses, including the Prius c).
Entrances and exits to the highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arterials and collector roads. On the controlled-access highway, opposing directions of travel are generally separated by a median strip or central reservation containing a traffic barrier or grass.
AEB differs from forward collision warning: FCW alerts the driver with a warning but does not by itself brake the vehicle. [4] According to Euro NCAP, AEB has three characteristics: [5] Autonomous: the system acts independently of the driver to avoid or mitigate the accident. Emergency: the system will intervene only in a critical situation.
HiPhi refers to this setup as "NT Doors". The HiPhi X is powered by a Bosch electric motor with a single-speed reduction gear producing 268 hp (200 kW; 272 PS) powering the rear wheels, with dual-motor all-wheel-drive models also available with a combined output of 536 hp (400 kW; 543 PS). [10]
