Where is the radar for ADAS in Song Plus 26?

https://preview.redd.it/xxzob328mulg1.jpeg?width=5712&format=pjpg&auto=webp&s=80b655b41f6e14f94be4714d5c89f53ad5c58eff Here it is. I removed this plastic cover and it’s empty behind it.

No idea but the ADAS on my 2025 song plus is worse than horrible, the Auto cruise control is completely unusable due to how jerky it is

All my ADAS features in Seal U DMI (Seallion 6, Song Plus) work perfect since eleven 11.000kkm

This is part of a broader shift within BYD to move toward a vision-based ADAS system (similar to Tesla’s "Tesla Vision"). Instead of relying on a dedicated radar unit for distance measurement, the 2026 model utilizes: High-Definition Cameras: A multi-camera setup (typically a tri-camera cluster behind the windscreen) that uses AI algorithms to calculate distance and speed of objects. Ultrasonic Sensors: These remain in the bumper (often listed as "2 front parking radars" in spec sheets), but these are short-range sensors for parking maneuvers, not the long-range radar used for high-speed cruise control. Performance: Despite the removal of the physical front radar, the ADAS features (ACC, AEB, Lane Keeping) remain functional. However, some early reports from the 2026 model suggest the vision-based system can be more sensitive to lighting conditions or heavy rain compared to the older radar-equipped versions.

Ok, but that would require cameras way more advanced. At least 2 cameras in the windshield to be able to tell distance (stereoscopic view) which doesn’t seem to be the case. My car has a single camera there. Maybe it’s more advanced than previous model? Maybe, but still a single camera. Doesn’t sound reliable as having that radar. Also, my car does not have the front park sensors, only corner sensors. There are place holders in the bumper but again, no parking sensors there to be found. Attached is a picture of the windshield camera https://preview.redd.it/evdd5pn80xlg1.jpeg?width=3577&format=pjpg&auto=webp&s=0608ad9b1fc0c28f17f4419896f2b773e4e3f68c

so it wasnt working perfectly before 11,0000? strange.... how did you fix it

🤣 no I mean everything works perfect from beginning until now (11k)

Oh nice, good to know

I asked the Chinese KiMI AI - Likely Reasons for the Missing Front Radar 1. Regional Regulatory & Certification Differences Brazil may have different ADAS certification requirements that allow camera-based systems without radar Some markets accept pure vision-based approaches (similar to Tesla's strategy), reducing hardware complexity 2. Cost Optimization for Price-Sensitive Markets Brazil has high import taxes and local production costs Removing the front radar reduces BOM (bill of materials) cost significantly This allows BYD to hit competitive price points against local competitors

Hey, are you able to check if your car has the radar sensor there?

Mmm weather is fine, I will have a look

ADAS is behind this position and other site the same https://preview.redd.it/4rurk4u0a9mg1.jpeg?width=3468&format=pjpg&auto=webp&s=9fdb55c733246d54bd0ddebc45141c30b5af9656

What do you mean? Any sensors there other than parking sensors?

Mine doesn’t. I removed and checked.

I made a picture from behind, can't upload. I mean the exact position my fingers pointing yes. Radar sensor approx 8x8 cm, both sides ...wait trying figuring out why upload nicht working

This is other side, from behind, because more space for cam Pictures top leads to car center. About 15cm away is the visible parking sensor, which can be seen from the bumper front

A third one, exact the same as left and right https://preview.redd.it/9i375nnyh9mg1.jpeg?width=3468&format=pjpg&auto=webp&s=ad15055fa86c700cad8a1bbb493a170a2502b851

Oh, I see. Interesting. I checked there and guess what? It’s empty! https://preview.redd.it/t1pxnu6zh9mg1.jpeg?width=1320&format=pjpg&auto=webp&s=9b6898506142266b7e5b316373e1fad24ff42d58

For me, it’s just another empty space 🥲 Edit: The square thing you see back there close to the radiator is just the speaker for the engine sound simulator. https://preview.redd.it/4bdlixm6j9mg1.jpeg?width=4032&format=pjpg&auto=webp&s=fdba7666d9de1c402ab8592666b1c68bd7de9a2d

My speaker is approx here https://preview.redd.it/cqlb9w98r9mg1.png?width=1080&format=png&auto=webp&s=fef28014f41d17aea74e22f7aa39572e68793a7d

Third one right center behind the cover, were others mentioned it's empty space at their car https://preview.redd.it/kus8m8tpr9mg1.png?width=1080&format=png&auto=webp&s=e2128372f060a26d0bcba0e8363f77d07ac3ddcc

Thanks for helping with this investigation, by the way. I really appreciate!
