Damn scary wei. Always keep 2 car distance away from prc car to be safe. If they behind you just let them pass.

This one is 996 programming issue affect all models. Tight deadline and bad mgmt likely push dev team to just cincai duct tape the end add catch all condition to hard break, lock tayars and shut down no matter what when got error. Damn scary.

Provided you can see them. When such EV blacks out on a dark highway how ? Just saw a video, the carcam travelling on center lane and suddenly it passed a silhouette of a stranded vehicle on the fast lane sudah kena accident without any lights at all. If the carcam on the fast lane, mana tak langgar.

Imagine a stranded EV without any power on the highway and an iCE smashes into it, which weighs more than the iCE. Mampus.

I smell bullshit.

Either BYD Malaysia just wanna keep something more sinister under wraps or BYD system architecture has a serious flaw where a non safety critical fault can trigger system shutdown. Even so, no reason to have car totally unresponsive.

We can only hope our authorities can intervene before something worse happens.

It's very simple to prove true or not, disable the door sensor while driving and see whether it causes emergency brake.

the car put itself in Electronic Parking Brake when I open the door, while it is in Drive.

Safety feature to prevent run a way car. Driver cannot simply just wedge a stick and jump out from driver door.

Why are we talking about driver opening the door ? Didn't the driver said that after his vehicle loss all power, he couldnt even open the door ? So funny la, got some even insinuated that the car stoped because the driver opened the door. Yeah right I am speeding on the fast lane with my family in the car and I just want to open the door.

ICE that manages to start under such conditions, will usually end up with a busted charging system at the end. Since EV charging system is different once the low voltage battery finishes it's the end.

How can the root cause a faulty sensor at the door drain the battery while it's in operation, makes no sense at all.

Faulty sensor, is link to the "Infotainment" system and "Driving" system, ... the so called "smart" car, even ask me when I use voice command to open the windows while crusing at 80km/hr... " Are you sure you want to open the window when the car is traveling at 80km/hr.


it is just an anecdote on how much the "smart" car is connected to the driving system. The so called safety system, will also put the car in Parking brakes(in this case electronic parking brake) when you suddenly open the door of the car without putting on the parking brake. So the car does not roll off while you get out of the car, without putting on the electronic parking brake.


All part of the system.it also have auto-hill hold, so at traffic lights, when we come to a stop, the brake is held down for us, after the car is stopped for 1-3seconds. and all that monitoring, is done by sensors. If you safety belt is not clipped, the auto-hill hold does not activate. Certainly, when the auto-hill hold brake is active, if you open the door... also the system switch to Electronic parking brake.


Hence, yes, those door open sensors are working full time and if you do not lock the doors, perhaps the sensor is constantly monitoring the door.


And yes, while the car is off, if the door is opened, it will also warn the passenger or driver that there is vehicle approaching from the back....


All that takes a lot of sensor and battery to keep running. Perhaps that is why it is getting so out of control with the 12 V battery getting used up. That is my 3 sen worth of knowledge after driving the car for 10k km. (M6 driver here)

Then why the Singapore Atto3 proceeded to move while the driver's door was open ? Where is the safety system ?

really? there is a few setting for auto-door locks, maybe he disable it as well? and or auto-power on when door is unlock. I keep those unchecked. but do not know if others keep it running. Open door and the car is ready and prime to move.



and honestly, I do not always try to drive the car with the door open, and the seat belt un-buckled. in the case, where I unbuckle and open the door while car is in "D" mode, directly it auto- engage EPB.


Did the person or the driver seat belt /seat sensor detected the driver is still in the car? *** alot of possiblity for malfunction. or edge cases one.

At least for ICE, when the battery is disconnected for whatever reason, the vehicle will still have another source of power ie the altenator albeit temporarily in case of an emergency. In EV once battery disconnected, terus black out. So when then Chinese guy decided to public with the limitation of the 12 volt battery, no wonder they silenced him quickly.

What the fuck? Why so many sensors are directly connected to the car's ability to be used?

Yes, Uncle also prefer a car with Zero safety system, purely use our own innate safety logic in the brain. therefore, I can only tell you as a user of the car, it does do certain things. But you do not need to question me. Go drive the car yourself and do a video on youtube to show the world it is not safe.

Think about it, this case was lucky that it happened during the day and those behind managed to avoid him by the skin of their teeth. If at night, he and his family might be dead and we wouldn't know any better.

This one I have tested on my own Atto last week.

Unbuckle and open door > straight engage EPB and park mode

However

With door still open, from P, press brake and push gear into D, the car starts rolling forward again, with the door still opened.

Will try to test again on another car with EPB to see if the algorithm logic is the same or not

What I wouldn't do or let my clients do is drive with a weak battery. But there will always be those who wants to push the envelope by going against me and when things go awry, I just say didn't I tell you so. But I am also grateful to these explorers la, if not for them, I also wouldn't learn from their mistakes.

aye aye, yes, the car can move, when the driver or any other passenger door is not properly closed. (the auto lock also will not complete its job of locking after the car travel up to speed) sometimes I use the locked led on the side panel to find out yes, one door is slightly ajar.

The thing is after it is properly closed and locked, and in Drive, and we open the door or unbuckle.... the system is monitoring and doing the EPB activation.

Walao you guys really do such testing huh to see which algorithm is logical ? Shouldnt that be like a standard operational procedure like that the vehicle is safely parked before opening the door and exiting the driver seat ?

Now it's the future la but when the number of EV fires begin to rise and the ridiculous damages sustained, I am sure they will change their tune one.

A car that takes control away from the driver is a major risk, and not a safety feature.

Imagine you are halfway overtaking on a 2-way lane but the car decides to reduce your throttle speed because it thinks you are driving "too fast" or "too recklessly" due to "lane departure" sensor ?

Not what EV fanboys think
They praise the day they get full self driving.
They say you are the OKU being unable to adapt to modern driving tech.
It is not the car that is the problem but you the driver is the problem.
