Embodiment 1

[0047] An intelligent driving system such as figure 1As 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=A1 F+A2 SPO2+A3 T+A4 P+A5 HR

[0051] Among them, A1...

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 brain wave frequency range combined with the rhythmic physiological activity 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 Alpha band corresponds to the state of being awake and relaxed with eyes closed, the Beta band corresponds to the state of active thinking or tension,...

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 activity of brain cell groups, and obtaining the brain state F by analyzing the frequency range of the brain wave combined with the rhythmic physiological activity of the brain; the brain state F can be divided into Delta, Theta , Alpha, Beta and Gamma 5 bands, in which the Delta band corresponds to the state of deep sleep, the Theta band corresponds to the state of drowsiness, the Alpha band cor...

Abstract

The invention provides an intelligent driving system and method. The intelligent system includes a vehicle analysis control system, and a fatigue sensing system connected with the vehicle analysis control system, an electronic map system, an automatic driving system, and a reminder system. The intelligent driving system and method provided by the present invention intelligently judge which driving mode to adopt according to the driver's comprehensive human body fatigue condition and the road condition environment where the vehicle is located, taking into account internal factors (driver's condition) and external factors (road environment) simultaneously. ) has an impact on the safety of the driving process, which greatly improves the safety of vehicle driving and reduces the driving pressure of the driver.

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...
