Embodiment 1

[0048] figure 1 It is a flow chart of an automatic driving control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of controlling the automatic driving mode, and is mainly used in the special level 4 highly automated driving that allows the driver to enter the sleep state. occasions and all scenarios of Level 5 fully automated driving, but the application scenarios are not limited thereto. The method may be executed by an automatic driving control device, and specifically includes the following steps:

[0049] S110. Determine the sleep state of the vehicle driver, where the sleep state includes sleep or wakefulness.

[0050] Among them, during the driving of the vehicle, the driver of the vehicle may become fatigued and enter a sleep state due to excessive driving time. At this time, there is a high possibility of a collision risk. In view of this situation, in order to avoid traffic accidents, it is determined that the ...

Embodiment 2

[0070] image 3 It is a flow chart of an automatic driving control method provided in Embodiment 2 of the present invention, such as image 3 As shown, the automatic driving control method provided in this embodiment includes the following steps:

[0071] S310, collecting pressure data of the driver's seat of the vehicle.

[0072] Specifically, the pressure data of drivers in various situations in a sleep state and in an awake state on the driver's seat of the vehicle are respectively collected, and the drivers in various situations include drivers of different age groups, different genders, and different health conditions.

[0073] S320. Input the pressure data into a preset sleep discrimination model to determine the sleep state of the vehicle driver.

[0074] Wherein, before inputting the pressure data into the preset sleep discrimination model and determining the sleep state of the vehicle driver, it also includes:

[0075] The collected pressure data of the driver in v...

Embodiment 3

[0104] Figure 4 It is a flow chart of an automatic driving control method provided in Embodiment 3 of the present invention, such as Figure 4 As shown, the method specifically includes the following steps:

[0105] S410, installing a pressure sensor on the driver's seat.

[0106] Optionally, pressure sensors are installed under the driver's seat and on the back to facilitate the subsequent collection of pressure data of the driver when he is asleep and awake.

[0107] S420, collecting data, performing cluster analysis, and extracting sleep feature information.

[0108] Optionally, because the age, gender, and health status of each driver are different, a large number of pressure data of the driver in the sleep state and awake state are collected as training data, and multiple preset sleep patterns are obtained through the K-Means clustering algorithm. discriminant model.

[0109] S430, the logic of judging whether to fall asleep and the logic of automatically switching t...

Abstract

The invention discloses an automatic driving control method and device and a vehicle. A sleep state of a vehicle driver is determined, and the sleep state comprises sleep or awakening; when the sleepstate of the vehicle driver is sleep, the vehicle is switched to an automatic driving mode; and according to the driving state of the vehicle, automatic driving mode switching is carried out, the automatic driving mode is a stable mode when the driving state of the vehicle is a normal state, and the automatic driving mode is an emergency mode when the driving state of the vehicle is an emergency state. According to the technical scheme provided by the embodiment of the invention, the problem that safety and comfort are not considered under the sleep state of the driver when the same set automatic driving control strategy is used when there is no driver and the driver falls asleep is solved, automatic driving control is more targeted, and the and the comfort and safety of automatic drivingare improved.

Description

technical field [0001] Embodiments of the present invention relate to automatic driving technology, and in particular to an automatic driving control method, device and vehicle. Background technique [0002] With the development of artificial intelligence technology, the automatic driving technology of vehicles has become an important research direction in the field of vehicles. Autonomous driving technology relies on the collaborative cooperation of artificial intelligence, visual computing, radar, monitoring devices and positioning systems, which can enable vehicles to automatically and safely operate motor vehicles without human active operation. [0003] According to the standards proposed by the Society of Automotive Engineers (SAE), autonomous driving technology is divided into 0-5 levels from no automation to full automation, of which 0 is no automation and 5 is unmanned. The levels are driver assistance, partial automation, conditional automation, high automation, a...
