The situation before the incident: How do you think that a female car owner in Henan took the Tesla roof to defend her rights, and the loudspeaker played “Model 3 brakes failed, and a family of four nearly died”?
Previously, it was mentioned in other answers that “if the car owner now agrees with the appraisal agency, there is a high probability that Tesla will have no problem in a short time.” Sure enough, before the appraisal agency came out, many people began to scold the car owner. The owner of the car could not take out anything except a mouth and a mobile phone. And Tesla can not only take out the data, but also take out all the bad habits and *** during your M3 period. At that time, the appraisal agency can only refer to the information provided by Tesla “voluntarily” to prove that Tesla no problem. Because Tesla is not stupid, there is definitely no problem with what you can get. You can’t get the others if you want. Is there any relevant agency that can force Tesla to provide true and complete back-end data? Of course, let’s not say who is right and who is wrong. Everyone still doesn’t understand. However, one party must be lying, the owner of the car was not the driver and was in panic, and the non-professionals’ statements must not be completely accurate. Tesla is very professional, shrewd and tough, and what it provides is not necessarily true. The owner can’t get anything out and is still in custody. She is now a passive receiver. Let’s not talk about her. Let’s talk about the data provided by Tesla. You don’t need to look at the data provided by Tesla to know that there is definitely no problem, but from the incomplete data sheet, you can still learn a little bit of Tesla braking system information. 1. From 118.5 to 109.5, only 9 is provided on average in 2 seconds. /3.6/2=1.25m/s², I haven’t tested the deceleration provided by Model 3 kinetic energy recovery at about 118, but I just measured the deceleration of about 1.6m/ when the switch is released at about 60km/h. s², of course, I don’t have the specific logic for the kinetic energy recovery of the M3 at different speeds, but I think the kinetic energy recovery deceleration should be greater at 118 hours. But the kinetic energy recovery of 118kph at the time of the accident plus brake pedal force and wind resistance provide a deceleration of 1.25m/s², which is not as good as the single kinetic energy recovery deceleration at 60kph. I don’t quite understand this. I hope someone can help. Interpretation, thank you first. 2. In addition, from (94-48.5)/3.6/(27.45-25.41)=6.3m/s², this data is not ideal. According to the M3 100kph braking distance of 35m, the deceleration is about 11m/s². The accident data is obviously much worse. 3. Some people may have doubts that the above calculation is not all the maximum brake. Then I want to say that this data is incomplete and I have no choice. But we will also do the math. At 74kph, it is considered full braking, from this moment on. (74-48.5)/3.6/(27.45-26.43)=6.9m/s², I didn’t want to understand, the difference between full braking and not full braking is not obvious, is it due to the steering effect or something else? It can’t be seen from the data now. Well, when it comes to this, I’m the same as everyone, but I can see that the braking effect of the M3 in this accident does not seem to be very good, and it is certain that the owner’s father did not get the “Electric Gate Star” like other owners. title. But who is lying is still unknown, maybe neither can be trusted. Or is there no lie between the two phenomena during braking? The pedal feel calibration curve should be in the middle of the upper limit and the lower limit. Because I feel that the M3 pedal is indeed hard and fails to provide pedal stroke signal data, so boldly guess if the M3 curve is as follows. The driver may indeed depress the pedal forcefully, but the result is that, as in Tesla’s data, it failed to generate enough master cylinder pressure to provide sufficient deceleration. Does this possibility exist? There is also a conjecture, ibooster has signal loss or bugs and other faults, even though the pedal is stepped on, it cannot provide assistance, which affects the braking efficiency. Correspondingly, Tesla believes that the driver did not pedal vigorously. Not to mention that the deceleration at 6 o’clock is almost the same as the full braking deceleration when there is no assist. The relationship curve between pedal force and deceleration is based on the current situation. Even if the appraisal agency intervenes, it is difficult to prove that Tesla has a problem. Therefore, it is estimated that the probability of failure of the owner is relatively high. Tesla also pointed out that it has exceeded 100kph many times before. Then please help the government to find the dash cam and previous intersection data. If there is speeding, end the farce early. If there is no speeding, although you may not be able to pay you justice, everyone will still support you.
