What is the difference between L1 and L2 autonomous driving?
1 Answers
L1: Assisted driving, L2: Semi-autonomous driving. The main difference is that L2 models have a higher degree of automation than L1. In L1, vehicles can only achieve partial automation of certain functions, such as automatic acceleration/deceleration or steering. Generally, features like adaptive cruise control, automatic braking, and lane-keeping assist fall under the scope of L1 autonomous driving. More details are as follows: 1. L1: Assisted driving. The vehicle can perform very limited functions, such as either acceleration/deceleration or steering, while the remaining functions require driver operation. L1 autonomous driving emerged over a decade ago, with features like adaptive cruise control, lane-keeping assist, and automatic braking found in luxury brands such as Volvo and Mercedes-Benz, all falling under the L1 category. 2. L2: Semi-autonomous driving. L2 autonomous driving has become a hot topic recently, with many affordable domestic-brand models already achieving this level. L2 enables the vehicle to perform multiple functions, while a few still require driver input. Common L2 features include full-speed adaptive cruise control, automatic parking, active lane-keeping, automatic lane-changing, and speed limit recognition. Tesla is a leader in this field, claiming to achieve L2.5 autonomous driving.
