Fatigue driving warning method, vehicle controller and vehicle

Abstract

The application discloses a kind of fatigue driving early warning method, vehicle controller and vehicle, belong to vehicle technical field, based on front road information whether the front of vehicle exists risk section, after determining that the front of vehicle exists risk section, from the state information of driver determines whether driver is in fatigue state, when determining that driver is in fatigue state, it can be predicted that the driving risk of driver in risk section is larger, then through vibration sensor obtains road vibration information in the process of vehicle travel, utilize electric control suspension system to be enlarged to road vibration information in proportion after directly transferred to the carriage of vehicle, trigger carriage vibration, and the frequency, amplitude and time of carriage vibration and other parameters are matched with the current road vibration information of vehicle, so that carriage vibration forms relatively unique vibration scheme, and then different from conventional and repeated wake-up scheme is used to wake up driver, avoid the tolerance ability of driver to wake-up scheme, improve wake-up effect.
