Safety first. 
Under the paramount value of "Safety first," we develop safe and reliable autonomous driving technology to provide opportunities for an equal and prosperous life through 'Mobility for All'.
WHY WE DO? 
Why do we need a safety strategy?
Autonomous driving has the potential to drastically change our future. Everyone agrees on this. However, for this vision to become a reality, we must prioritize safety. The foremost value of autonomous driving is safety. We understand that safety cannot be compromised for any other value. Until a system that can handle emergencies is developed, the value of safety must not be underestimated.
SAFE STRATEGY 
1. Fallback 
Fallback is a protocol where a level.4 autonomous vehicle, upon determining that it is difficult to drive or encountering a safety-related system error, transfers control to a remote driver in the control center to maintain the vehicle in a safe state.
Step 1
Next Station Stop 


In case of a fault that can be handled with system redundancy, the vehicle continues to the next station.

Step 2 
In-Lane Stop 


In case of a fault that makes autonomous driving difficult, the vehicle safely stops while maintaining its lane.

Step 3 
Straight Stop 


In case of a severe fault where lane maintenance is difficult, the vehicle stops immediately.

Remote Control


This remote control driving function is designed for emergency situations where autonomous driving is not feasible. It enables real-time monitoring of road conditions via cameras and 5G wireless communication modules equipped on unmanned autonomous vehicles, and transmits control commands from the remote driver to the autonomous vehicle to control movement.
