Document Type and Number:
WIPO Patent Application WO/2022/124163
Kind Code:
A1
Abstract:
An awakening device (1) comprises a plurality of operation patterns for each drowsiness level. The awakening device (1) is configured so that if the drowsiness level is constant, the operation pattern corresponding to the current drowsiness level is switched and executed at each prescribed standard time duration (T1). If the state of a driver at a timing at which a prescribed intermediate confirmation time (T2) from the start of the operation pattern currently being executed has elapsed satisfies a prescribed special switching condition, the awakening device (1) switches the operation pattern to a prescribed pattern without waiting for the standard time duration (T1) to elapse.
