September 2, Tesla “T-Talk” with the theme of car safety The lecture hall was held in the center of Southern Second Ring Road. As the pioneer in the electric vehicle industry, Teslin is known for the persistence of safety quality, and has always used safety as the weight of the vehicle design, in the “T-Talk” lecture, Tesla, “Five Star Safety The bottom line “and reveals the logic behind the five-star safety by analyzing the domestic MODEL 3 white car design and a journey of the early autumn test drive.
As the offline activities initiated by Tesla, “T-Talk” is invited by the official regular invitation to people from all walks of life to explore the current situation, technology development, and common. Promote the progress of the industry, build a bridge that communicates with the media and the public. This event, not only “started”, not only the Tesla Model3 white car and Tesla “design are safe as the first”, but also let participation media feel special in the test drive. Slash “invisible” active security.
Passive safety | The concept is the first to safety
, Tesla has very strict high standards in safe design. In the latest US National Highway Traffic Safety Administration (NHTSA) collision test, Tesla all models received five-star collision safety rating. Among them, Model 3 not only obtained NHTSA full five-star safety rating, ENCAP all five-star rating, but also won the IIHS Safety Pick + top security award. In the “New Car Evaluation Project” of the US government, Model 3 vehicles are low in any vehicle injury probabilities of their tests.
The rigidity and structure of the body is an important standard for measuring passive safety. In the T-Talk scene, Tesla and participating guests discussed in-depth discussion for the Model 3 white car, and the details of passive safety design were more clearly presented.
Model3 White Body
Model 3 The body uses steel aluminum mixed material body frame, which can withstand more impact, laser welding, resistance welding, riveting, rubber, etc., etc., also further enhance the strength of the body. In addition, several H-shaped anti-collision structures of the Model3 head and passengers can effectively reduce the risk of vehicle deformation in vehicle collision accidents. The passenger compartment uses a safe cage structure, and its structure has a plurality of collision transmission paths that can correspond to all side collisions.
On the basis of the body structure, Tesla also reinforces the collisions and columns of the A column and B columns. The amount of the left and right inner plate and the reinforcing plate of the A column use a thermoforming material greater than 1000MPa. The sheet metal thickness is higher than the homologous model. The reinforced A column can effectively reduce the deformation of the door frame in the offset crash. Model3 has achieved excellent results in 40 percent collision test in front of IIHS.
In the B-column reinforcement design, Tesla adds a reinforcing plate in the B column, but also integrally forms a two-layer reinforcing plate in the side beam, and can correspond to at least 4.5 times or more. Gravity, which makes Model3 in NHTSA, ENCAP, and IIHS collision test results very well.
The goal of all stringent collision tests is to create a safer product. Different from traditional energy models, pure electric vehicles in security design, in addition to safeguarding the safety of the occupants, it also focuses on the protection of the battery. On the one hand, two collars in the Model3 battery pack replace the traditional force strip to ensure efficient transmission of the collision force and battery safety. In the main deformation resistance zone in the middle of the body, the threshold is a reinforcing beam in the body. When the side touches or columns occur, the passengers and batteries can be better protected, and the risk of collision is minimized. .

On the other hand, the left and right penetration of 1700 MPa will further improve the body structure strength, which can effectively avoid collision, extrusion pair The damage of the battery is greatly reduced by the risk of extruded passenger compartments.

It is worth mentioning that the Model 3 body material is arranged beforeAfter the steel, the motor is arranged in the rear, and the rear end uses lightweight aluminum parts, which can balance the weight of the motor. Under the premise of ensuring effective collapse and occupant protection, it is better to achieve nearly 50:50. A shaft load is assigned to provide better handling performance.
From Tesla’s overall passive security system, you can see Tesla’s full use of passive safety technology, as well as the ultimate guards of the driver. It is because of Tesla “design with security first”, in a series of collision tests, Tesla’s full model can achieve such excellent results.
Active safety | Wisdom enables security and then adding a defense line
Not just passive security, as the user’s safety travel awareness is enhanced, reliable active safety performance is becoming more and more attention And Tesla has been considered to be leaders in this field, and its great achievements have been taken in active safety.
Data in Tesla “In the First Quarter Vehicle Safety Report” in 2021, the average traffic accident occurred in average 6.74 million miles in the driving process of AutoPilot automatic assistance driving. The NHTSA data in the United States shows that traffic safety accidents occurred every 7.8 million in road traffic. Tesla AutoPilot automatic assist driving allows driving safety level to reach 8.66 times the average level of the average! 
Tesla has high security in terctance of active safety, which is mainly reflected in AutoPilot automatic assistance. All Tesra models are currently assigned AutoPilot automatic driving, which help users make droplets, effectively reduce the incidence of accidents.
AutoPilot automatic assistance driving based on computer vision, the body is spread throughout the advanced sensor and the camera, build an automatic driving assistance system, active safety system, can predict the risk, pre-judgment, implement steering, acceleration and braking Waiting for decisions, try to avoid accidents.
For example, in avoiding side collisions, Tesla side hit warnings play a crucial role. Take Model 3 as an example, when MODEL 3 is incorporated byWhen the vehicle is detected in the lane, Autopilot automatic assist driving triggers the side hit prevention function (steering intervention) and ensures that the vehicle automatically turns to a safer position.
In the test drive link, the media drove Tesla Model Y and Model 3. After the Northwestern Polytechnical University and Fengqing Park, feel the natural beauty in Xi’an City in the autumn. With a cultural atmosphere. On the way, Tesla AutoPilot automatically supported the media left a deep impression: “The side hit warning function is very sensitive, and the intervention is very close to human driving habits, and it is particularly relaxed.”
The evolution and improvement of the auxiliary driving function, Tesla vehicles can be upgraded through OTA air software updates. In the future, Tesra’s vehicles will provide users with smarter and safer travel experiences. 
Since the time, Tesla is “centered” principle, “all-round guardian travel safety,” safe-first “design concept, reflect On Tesla per vehicle. Through this T-Talk activity, we deeply explained the mystery of car safety, and he has seen Tesla’s deep concern for consumers. Tesla has a full-scale security quality, let us believe that electric cars will not be far away!
