310. And the terminal equipment determines the fatigue driving relieving mode corresponding to the critical state and outputs the corresponding fatigue driving relieving mode in a voice mode.
It should be noted that, when the terminal device determines that the continuous driving time is equal to the first preset time threshold, before performing steps 309 to 310, the terminal device detects whether the user continues driving, and if not, when it is detected that the time during which the user does not drive exceeds a second preset time threshold (for example, 20 minutes), the process may be ended, that is, the terminal device controls the timer to restart; if it is detected that the user continues driving, steps 309-310 are triggered to be performed.
It should be noted that, when the continuous driving time is less than the first preset time threshold and equal to a preset multiple of the first preset time threshold, the terminal device may early warn, where the preset multiple is greater than 0 and less than 1.
Further, when the continuous driving time reaches a third preset time threshold, the terminal device determines that the user belongs to a heavy fatigue state, and the terminal device may automatically send the current geographic position and the heavy fatigue state information to a preset alarm platform, such as a 110 alarm platform, in addition to the above operations, where the third preset time threshold (such as 8 hours) is greater than the first preset time threshold (such as 4 hours).
Therefore, by implementing the method for reminding fatigue driving described in fig. 3, whether the user is fatigue driving can be automatically judged according to the driving time of the user, and when the user is judged to be fatigue driving, a prompt is output to the user, so that the applicability is strong, the functions of the terminal equipment are enriched, and the use experience of the user is improved.
