About how specifically LMDrive works

Opened this issue · 1 comments

Thanks for the great work!

I am new to LLM-based ADS, and I have some questions about how LMDrive works. As stated in the paper, LMDrive is developed based on Q-former. And how Q-former works is as below:

As I took it, the key idea of LMDrive is to use the idea of Q-former for LLM-based driving. Efforts done in the paper is to training the Q-Former, merging multi-sensor data, and so on. Is this understanding correct?

Additionally, what is the specifically output of LMDrive? It seems to output future waypoints instead of direct control signals.

Many thanks for your attention!

Hi!
Sorry for the late reply. I've been very busy lately.

Q-former is not the core contribution of our paper. We utilize it primarily to save tokens and accelerate the process. Yes, LMdrive outputs the future trajectories, which are then converted into control signals by the PID controllers.
