Problems solved by technology

The original intention of the adaptive cruise design is to reduce the fatigue of the driver on long-distance driving. However, in the adaptive cruise mode for a long time, the driver will also be fatigued due to boredom.
In the prior art, there is no technical solution for the strategy interaction and integration of the adaptive cruise control system and the fatigue driving monitoring system

Embodiment 1

[0059] figure 1 It is a flow chart of the vehicle control method provided by the embodiment of the present invention. For simplicity, only those steps related to the subject matter in the text are shown. The overall vehicle control method may also include many other steps. Such as figure 1 As shown, the method includes the following steps:

[0060] S101: When the adaptive cruise system is turned on, acquire the physiological state information of the driver and / or the state information of the own vehicle;

[0061] S102: Determine the fatigue level of the driver according to the driver's physiological state information and / or the vehicle state information;

[0062] In some embodiments, the fatigue level includes a first fatigue level and a second fatigue level, wherein the degree of fatigue represented by the second fatigue level is higher than the degree of fatigue represented by the first fatigue level. It should be pointed out that those skilled in the art can also divid...

Abstract

The invention discloses a vehicle control method and system, and equipment. The method comprises the following steps that physiological status information of a driver and / or vehicle state informationare / is acquired when an adaptive cruise system is in a turned-on state; the fatigue grade of the driver is determined according to the physiological status information of the driver and / or the vehicle state information; when the fatigue grade reaches a first fatigue grade, the driver is reminded to take over the control of the vehicle; and when the fatigue grade reaches a second fatigue grade, the vehicle is controlled to reduce speed to run along the current running lane until the vehicle speed is zero. According to the vehicle control method, aiming at different fatigue grades, a vehicle control strategy conforming to the actual driving working condition is adopted, so that continuity, comfort and safety in the driving process are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving assistance, in particular to a vehicle control method, system and equipment. Background technique [0002] The fatigue driving monitoring system (DMC) mainly monitors the driver's fatigue state through the internal camera's recognition of the face state or the judgment of the vehicle's state signal, and reminds the driver through sound, touch or vision. Ensure driving safety. [0003] The adaptive cruise control system (ACC) mainly relies on the radar sensor to detect the target in front and relies on its own logic algorithm to control the cruise follow control of the vehicle by setting the speed and time distance between vehicles. The original intention of the adaptive cruise design is to reduce the driver's fatigue during long-distance driving. However, if the driver is in the adaptive cruise mode for a long time, the driver will also be fatigued due to boredom. In the prio...
