Automatic driving vehicle takeover prompting method and device, electronic equipment and program product
By identifying the driver's activity level and using electrical stimulation parameters to wake the driver in the autonomous driving system, the problem that conventional reminder methods cannot wake up resting or sleeping drivers has been solved, thus improving the driving safety of autonomous vehicles.

AI Technical Summary
When existing autonomous driving systems encounter scenarios that exceed their processing capabilities, conventional alert methods are unable to effectively wake up drivers who are resting or asleep, leading to failed takeover requests and potential traffic safety hazards.
By acquiring the takeover request signal from the autonomous driving system, and combining it with the driver's physiological state signals, facial image information, and cockpit interaction information, a multi-branch convolutional neural network is used to identify the level of activity. When the level of activity is low, targeted reminders are given using electrical stimulation parameters, including adjustments to the intensity and frequency of electrical stimulation.
It improves the reliability of autonomous vehicle takeover alerts, ensuring that drivers wake up and take over within the takeover time limit, reducing the risk of traffic accidents, and taking into account both driver safety and comfort.
