Embodiment Construction
[0043] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.
[0044] like figure 1 As shown, a vehicle control method based on monitoring driver status according to a preferred embodiment of the present invention includes the steps:
[0045] S11, identify an obstacle, and obtain obstacle information; wherein, the obstacle information includes the area where the obstacle is located;
[0046] S12, monitor the current driver's sight direction, and obtain the current driver's sight attention area;
[0047] S13, modifying preset collision warning parameters according to the obtained obstacle information and the obtained current driver's sight attention area; and,
[0048] S14, control the alarm system to perform an alarm operation or control the brake syste...

The invention relates to the technical field of vehicle safety, and discloses a vehicle control method, device and system based on monitoring the driver's state. The vehicle control method based on monitoring the driver's state first obtains the area where the obstacle is located and the current driver's implementation focus area , and then modify the preset collision warning parameters according to the area where the obstacle is located and the current driver's line of sight focus area, and finally, according to the corrected collision warning parameters, control the alarm system to perform an alarm operation or control the braking system to perform a braking operation . Obtain the attention area of the current driver's sight by monitoring the current driver's sight direction, so as to know the current driver's driving state in time, and correct the collision warning parameters according to the current driver's driving state, so as to realize timely control of the alarm system to perform alarm operations or Control the braking system to perform the braking operation, thereby avoiding that the warning operation or the braking operation cannot be triggered in time when the driver's attention is not concentrated.
Description
technical field [0001] The present invention relates to the technical field of vehicle safety, and in particular, to a vehicle control method, device and system based on monitoring driver status. Background technique [0002] At present, many existing models have been equipped with vehicle control system, which is mainly composed of three modules: ranging module, data analysis module and actuator; among them, the core of ranging module includes microwave radar, lidar and video system It can provide the vehicle with safe, accurate, real-time image and road condition information of the road ahead. The existing vehicle control system first uses radar to measure the distance between the vehicle and the preceding vehicle or obstacle, and then uses the data analysis module to compare the measured distance between the vehicle and the preceding vehicle or obstacle with the alarm distance and safety distance. When the distance from the vehicle in front or the obstacle is less than t...
