This invention relates to the field of control methods for public transportation equipment, specifically to a control method for LED wall washer lights for driver fatigue wake-up in long tunnels. The method includes: calibrating driver fatigue-sensitive sections in each spatial unit of the entire tunnel and completing alignment; updating the vehicle's spatial unit and collected parameters in real time to classify the driver's real-time fatigue state; generating a fatigue wake-up light signal encoding parameter set for the vehicle corresponding to the current driving tracking ID, the current fatigue state, and the current spatial unit; and driving the wall washer lights to generate optical flow signals according to the set parameters. This invention constructs an optical flow signal framework deeply bound to the driving state, simultaneously achieving both fatigue wake-up and directional navigation functions. It also binds the driver's real-time fatigue state classification to a stepped stimulation level, ensuring that the optical flow signal only acts on the surrounding visual area corresponding to the tunnel sidewall, without interfering with the driver's observation. This spatial distribution eliminates the interference of dynamic lighting on normal driving observation.
