Hello, I was interested in trying an automotive radar for collision avoidance on a UGV. Automotive radar should be cheaper than LIDAR due to scale production and no moving parts, and requires less…Continue
"I will try to answer questions the best i can based off the materials and courses ive received from audi and field experience. Unfortunately, processor, micro controller information is not typically info they disclose or teach us about, as they most…"
"KCMastaPeace, That was extremely helpful! I myself do not have any ongoing projects involving radar, but am very eager to learn about it.
What I think is important is two points. First, one need to know the 'hackability' of these…"
Im going to first start off by saying this is my first time ever posting on any forum. Ive read through several forums, just never been interested enough to actually post. While i work as an Audi Technician at a dealer, i have higher…"
I work with Kvaser, so it's nice to see the Leaf Light in the tool chain above : ) Just as an FYI:
- You're probably using CANking to record the log file, right? You can also replay a log file or send specific…"
XCP on CAN is interesting. The measurement bandwidth is quite limited compared to proper XCP on ethernet, but it should be sufficient to measure some simple info depending on how heavily loaded the CAN bus is already.
There are a few…"
"You're right. It seems to be very hard to get those automotive radars working out of the car. What I've read so far (and what it makes it even more difficult) is the fact, that audi (where the sensors used here come from) have component…"
"You're correct that there is some limited self correction functionality, but the sensor has no way of knowing where it is and where it's pointed. It needs to be told these things via diagnostic commands which are either executed at the end…"
the alignment procedure you describe is correct, but the fine calibration (+/- 0.8°) the sensor does itself. And because only the LRR itself knows it's actual position, my thought was that there must be any kind of a sensor which…"
There is no gyro or accelerometer on the LRR3 or any automotive radar that I know about, they typically receive data on the vehicle motion from the ESC system.
The alightment error is because the system needs to be aligned to very high…"
I've bought one lrr3 but hadn't any time to test it yet. As far as I know, the Bosch sensors have some kind of gyroscope onboard and throw out an error on CAN when the sensor isn't aligned properly. I've seen that you…"
* I'm not sure what type of sensor should I use, but due to poor range of sonic or laser sensors (I need at least 40m/130ft) I think that I have no other choice than radar sensor.
LIDAR is possible but expensive. There was some…"
I'm interested in making an adaptive cruise control unit to my old Honda as a final project at uni and I would be much grateful for some helping informations about radar sensors. I'm not sure what type of sensor should I use, but…"
