Embodiment 1
[0051] A safe intelligent driving method, comprising the steps of:
[0052] S1. Fatigue sensing system 2 monitors the driver's physiological indicators, and sends the monitoring results to fatigue analysis and vehicle control system 1. Fatigue analysis and vehicle control system 1 calculates the comprehensive human body fatigue index through the monitoring results of the driver's human physiological indicators I;
[0053] Among them, the fatigue sensing system 2 includes:
[0054] Brain wave signal acquisition module 201: connected to the driver's scalp, recording the spontaneous and rhythmic activities of brain cell groups, and obtaining the brain state F by analyzing the frequency range of the brain wave and combining the rhythmic physiological activities of the brain; the brain state F can be divided into There are five bands: Delta, Theta, Alpha, Beta, and Gamma, among which the Delta band corresponds to the state of deep sleep, the Theta band corresponds to the state of ...
Embodiment 2
[0078] A safe intelligent driving system, such as figure 2 As shown, it includes: fatigue analysis and vehicle control system 1, fatigue sensing system 2 connected with fatigue analysis and vehicle control system 1, vehicle status database 3, sensor perception database 4, geographic information database 5, automatic driving system 6, reminder System 7; where:
[0079] Fatigue Analysis and Vehicle Control Systems 1:
[0080] It is used to obtain the comprehensive human fatigue index I from the monitoring results of the human physiological indicators monitored by the fatigue sensing system 2. The comprehensive human fatigue index I is obtained from the monitoring results of the human physiological indicators. The saturation SPO2, human wrist temperature T, human blood pressure index P and heart rate HR are calculated. The calculation formula of human comprehensive fatigue index I is as follows:
[0081] I=A 1 F+A 2 SPO2+A 3 T+A 4 P+A 5 HR
[0082] Among them, A 1 、A 2...

Abstract
The invention discloses a safe intelligent driving method and system. The method comprises the following steps: obtaining a human body comprehensive fatigue index I by a fatigue analysis and vehicle control system through monitoring results, monitored by a fatigue sensing system, of physiological indexes of a human body; predicting whether a vehicle is in a safety region or not according to vehicle state data of a vehicle state database, perception data of a roadside sensor and a vehicle sensor of a sensor perception database, and vehicle driving route data of a geographic information database; and judging and selecting driving modes according to driving time, the human body comprehensive fatigue index I and whether the vehicle is in the safety region or not, and sending a control instruction to an automatic driving system according to judging results. The safe intelligent driving method and system disclosed by the invention have the beneficial effects that the influences of the driving time, human body comprehensive fatigue conditions and whether the vehicle is in the safety region or not on vehicle driving safety are comprehensively taken into account; a more appropriate drivingmode is intelligently selected; the vehicle driving safety is greatly improved, and the driving pressure of a driver is relieved.
Description
technical field [0001] The invention belongs to the technical field of intelligent driving, and in particular relates to a safe intelligent driving method and system. Background technique [0002] Fatigue driving is one of the main causes of traffic accidents, which seriously threatens people's lives and property safety. When the driver is tired, the ability to judge is obviously reduced, the reaction is slow, and the operation errors increase. If the driver still drives the vehicle reluctantly, it may lead to the occurrence of traffic accidents. In the process of driving, in addition to the driver's driving fatigue, the state of the vehicle itself, the driving route of the vehicle, and the environment around the vehicle will all have an impact on driving safety. How to accurately judge the driver's fatigue driving state through the intelligent driving system, and comprehensively consider the driver's state, the vehicle's own state and the influence of environmental factors...
