Embodiment 1

[0047] An intelligent driving system such as figure 1 As shown, it includes: a vehicle analysis control system 1, and a fatigue sensing system 2 connected to the vehicle analysis control system 1, an electronic map system 3, an automatic driving system 4, and a reminder system 5; wherein:

[0048] Vehicle Analysis Control System 1:

[0049] It is used to obtain the driver's comprehensive human fatigue index I from the monitoring results of the driver's human physiological indicators monitored by the fatigue sensing system 2; the human comprehensive fatigue index I is obtained from the monitoring results of human physiological indicators, and the monitoring results of human physiological indicators include brain State F, blood oxygen 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:

[0050] I=A 1 F+A 2 SPO2+A 3 T+A 4 P+A 5 HR

[0051] Am...

Embodiment 2

[0069] A kind of intelligent driving method, comprises the steps:

[0070] S1. The vehicle analysis control system 1 obtains the human body comprehensive fatigue index I through the monitoring results of the human body physiological indicators monitored by the fatigue sensing system 2;

[0071] Fatigue Sensing System 2 includes:

[0072] 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 drowsiness, the Alpha band corresponds to the state of being awake and relaxed with eyes closed, the Beta band corresponds to the state of active t...

Embodiment 3

[0088] A kind of intelligent driving method, comprises the steps:

[0089] S1. The fatigue sensing system monitors the driver's human physiological indicators, and sends the monitoring results to the vehicle analysis and control system, and the vehicle analysis and control system calculates the comprehensive human body fatigue index I through the monitoring results of the driver's human physiological indicators;

[0090] Among them, the fatigue sensing system includes:

[0091] Brain wave signal acquisition module: 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 Delta , Theta, Alpha, Beta, and Gamma have 5 bands, among which the Delta band corresponds to the state of deep sleep, the Theta band corresponds to the state of drowsiness, the ...

Abstract

The invention provides an intelligent driving system and method. The intelligent system comprises a vehicle analysis control system, a fatigue sensing system, an electronic map system, an automatic driving system and a reminding system, wherein the fatigue sensing system, the electronic map system, the automatic driving system and the reminding system are connected to the vehicle analysis controlsystem. According to the intelligent driving system and method provided by the invention, which driving mode is more appropriate is intelligently judged according to the comprehensive human body fatigue condition of a driver and road condition environment in which a vehicle is located, and the impact of an internal cause (the driver condition) and an external cause (the road environment) on the safety of a driving process is taken into consideration at the same time, so that the safety of vehicle driving is greatly improved, and the driving pressure of the driver is reduced.

Description

technical field [0001] The invention belongs to the technical field of intelligent driving, and in particular relates to an intelligent driving system and method. Background technique [0002] With the development of science and technology, smart driving cars are gradually becoming known to people. The intelligent driving system can use the on-board sensor system to obtain relevant information about the vehicle and the driver, and intelligently select a more appropriate and safe driving method. 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. If the intelligent driving system can accurately judge the driver's fatigue driving state, the safety of intelligent driving can be...
