Question 1:
Tesla's latest Model 3 Huan model has updated the owner's manual and added some new safety features, including an "active front cover protection" function. When the vehicle speed is between 30 and 52 km/h, the front sensor of the vehicle detects a collision with a pedestrian, and the vehicle will automatically raise the rear of the protective front cover by approximately 80 mm to reduce the risk of injury or death. An alert will appear on the touchscreen and, if visibility is not affected, the vehicle can be driven to a Tesla service center for maintenance.
In addition, Tesla's new configurations have been equipped on multiple models, such as Honda Accord, Acura RL and Citroen C6. The car company has also developed a pedestrian airbag system, which can deploy an airbag between the two headlights to provide better protection.
Question 2:
The ELR three-point seat belt is equipped with an ELR tightener, which allows the seat belt to be pulled out freely, and is equipped with an impact sensing device to lock the seat belt in the event of a collision or emergency braking. This structure has become mainstream. The ALR three-point safety belt is equipped with an ALR tightener and is mainly used to secure child seats. Many mid- to high-end cars are equipped with seat belts with pretensioners and force limiters. The pretensioners are used to eliminate excessive tension, and the force limiters are used to reduce pressure on the occupants.
I hope this simple organization method is helpful to you.
