The one-pedal mode, which has been banned before, why can it be used again?

The one-pedal mode, which has been banned before, why can it be used again?

Brothers, remember a while ago when the one-pedal mode was banned by the new national standard.

At that time, Brother Neck also wrote an article "The single pedal is going to be banned, but only half of it is banned." to celebrate that this anti-sky driving mode is finally going to be eliminated.

Well, the result is just two days ago, The draft of the all new version of the national standard is here.,The one-pedal mode can be used again in it.。。。

On September 20th, our Ministry of Industry and Information Technology, that is, the Ministry of Industry and Information Technology, said on its official website that in order to update the mandatory national standard of "Technical Requirements and Test Methods for Passenger Car Brake System", they will solicit opinions from the society for the second time.

It's a bit like the internal test of the experience server before the release of the major version of the game, and it definitely needs to collect a wave of player opinions, improve and improve it before putting it on the official server.

The first round of internal testing of the new national standard for this braking system is from the end of May to the end of July this year, and it is obvious that the test is completed, and everyone has a lot of opinions, so the Ministry of Industry and Information Technology spent two months iterating a new version, called "Technical Requirements and Test Methods for Passenger Car Brake Systems (Second Draft for Comments)", from September 20 to October 20 to solicit opinions for another month.

If there are no problems, update to the official server.,In case there are still a lot of opinions, continue to iterate.。

The one-pedal mode, which has been banned before, why can it be used again?

Conscience operated belonged to is.

The biggest difference between the two beta versions of the national standard is actually to get back the single-pedal mode that was completely banned before, but there is an additional precondition.

When you look at the one-pedal filthy earth reincarnation, you will definitely say, "Oh, brother neck, aren't you a slap in the face!"

But don't worry, this update doesn't conflict with the old version, and it's closer to a full score.

As for why, let's take a look at the changes.

In May, the first internal test version of the one-pedal mode dog leash was announced, that is, the "Technical Requirements and Test Methods for Passenger Car Braking System" (draft for comments), a sentence was added compared with the current national standard.

This is f) in clause 5.2.18:

In the case of Type A and vehicles with both Type A and Type B electric regenerative braking systems, the braking effect achieved by releasing the accelerator pedal in Forward gear does not slow the vehicle to a stop.

The one-pedal mode, which has been banned before, why can it be used again?

Translated in human terms, if your new energy model can recover kinetic energy, that is, as long as you release the accelerator (or electric valve?) Pedals, without stepping on the brakes, can be decelerated by converting the kinetic energy of the car into the electrical energy of the battery, then this deceleration cannot be reduced to 0, only the same as the idle speed of the oil car, reduced to a slow forward speed.

The one-pedal mode, which has been banned before, why can it be used again?

To brake completely, you have to move your foot from the accelerator pedal to the brake pedal and apply the brake.

And what we often call the one-pedal mode is to ignore the brake pedal at all when driving in daily life, accelerate when you step on the accelerator, slow down when you lift the accelerator, and keep the accelerator at a constant speed if you don't move. If you want to stop, just let go completely, and the car will eventually slow down to 0.

One thing to say, for some users, such as the two Tesla owner colleagues of Brother Neck, the one-pedal mode is very convenient for daily commuting. There is no need to change feet frequently in traffic jams, and the speed control is more accurate.

The one-pedal mode, which has been banned before, why can it be used again?

It allows users to gradually forget about the existence of the brake pedal, which is also the biggest problem of the one-pedal mode.

In recent years, whether it is Tesla or other models, whether it is domestic or foreign, we often see traffic accidents caused by accidentally stepping on the accelerator.

After all, compared to the traditional brake is the brake and the accelerator is the accelerator, the one-pedal mode is essentially a composite operation, that is, one of your actions may correspond to N different results.

Take the action of pressing down the pedal, on the oil car, this action is bound to different pedals, and there is only one result:

Slow down by pressing the brake and accelerate by stepping on the accelerator, which is very distinguishable and easy to operate.

When it comes to one-pedal mode, pedaling down means a lot. The acceleration of the car is to step on the accelerator, and the deceleration of the car is also to step on the accelerator, but the force is not so great, and the car is still stepping on the accelerator at a constant speed, that is, it is necessary to maintain the same strength all the time.

This logic may not be much when you are driving, but when you encounter an emergency that requires a reaction of a few tenths of a second, it is very prone to problems.

For example, when emergency braking is required, should you press the brakes to slow down, or lift the accelerator to slow down?

If you choose to step on the brakes, is it possible for users who do not have the habit of braking on a daily basis to mistake the car for the general situation of slowing down and pressing the accelerator, and mistakenly think that they are stepping on the brakes?

Don't think it's impossible, there have been several serious vehicle loss accidents in China before, the owner insisted that there was a problem with the braking system, and he slammed on the brakes and did not slow down, and the final investigation result was that he stepped on the wrong pedal.

So back to the first internal test, the rule that you must step on the brakes when parking is actually to force everyone to step on the brakes every time you stop, remember to change your feet to slow down, and reduce the possibility of everyone stepping on the wrong pedal in case of emergency.

It's so stipulated, safety is definitely safe, but don't forget, there are still some car owners who think that the single pedal is easy to use. People have been driving a single pedal for several years, and as we said earlier, the brakes may not work.

With such a change, it is really difficult to say whether it is safer or more dangerous.

So this second round of closed beta a few days ago, that is, on the basis of the previous version, gave the green light to the one-pedal mode, but also added some restrictive conditions. The specific content is as follows (the picture can not be seen, and there is a version of the word below).

The one-pedal mode, which has been banned before, why can it be used again?

To put it bluntly, the one-pedal kinetic energy recovery mode, which can slow down the car to 0, can still be used. But just like the oil truck has to manually turn off the engine every time you get on the car (X), it must be manually turned on every time the owner gets on the car.

And when turning on the one-pedal mode, there must always be a clear sign to inform the owner, so as not to make the owner remember what state it is now, resulting in misoperation.

This is equivalent to adding a fan filter to the one-pedal mode, if you really like the one-pedal to get on the car and operate for a second or two, the more insensible is still to use the default, safer mode that needs to step on the brakes.

The one-pedal mode, which has been banned before, why can it be used again?

Leaving it to users to choose whether to use it or not is the intention of this second round of internal testing, and it is also a more reasonable change that I think is more reasonable than the first round of internal testing.

However, here the neck brother still has to remind everyone, although this one-pedal mode seems to be confirmed for the time being, and everyone can freely choose to use it or not in the future, but I very much do not recommend that old drivers who have just got a driver's license or have been driving a fuel car for many years use it on the road immediately.

Because its operating logic is far from that of a driving school and a fuel car, before using it, it is best to familiarize yourself with the various characteristics of the tram, such as the foot feeling of kinetic energy recovery, etc.

Safety is paramount.

Another point that I am more emotional about is that the cold technical regulations of the mandatory national standard for automobiles have begun to consider the more subjective factors such as user habits and market preferences in the process of revision.

Then perhaps areas such as modification and classic cars, which are strongly related to car culture but do not comply with existing regulations, will gradually be opened up in the near future.

Which will be the next mandatory national standard that can be so humane? It's a little bit of a look forward to it.
