Embodiment 1

[0041] This embodiment provides a driving risk warning method, which includes:

[0042] S101: Obtain the vehicle status, vehicle location, predetermined route of the vehicle, and road conditions, traffic conditions, and weather conditions of the road section on the predetermined route.

[0043] S102: According to vehicle conditions, road conditions, traffic conditions, and weather conditions, use a pre-established BP network to classify corresponding road sections as high-risk road sections or low-risk road sections.

[0044] S103. Send a warning message to the vehicle to control the vehicle to issue a warning when driving to a high-risk road section.

[0045] In the driving risk warning method of this embodiment, the risks faced by the vehicle driving on different road sections can be calculated according to vehicle conditions, road conditions, traffic conditions, weather conditions, etc., and a warning is issued when the vehicle is driving to a high-risk road section. Remind the dri...

Embodiment 2

[0047] Such as Figure 1 to Figure 3 As shown, this embodiment provides a driving risk warning method, which is used to issue a warning when the vehicle is driving to a relatively dangerous road section to remind the driver to pay attention, thereby reducing the possibility of an accident.

[0048] Specifically, the driving risk warning method includes the following steps:

[0049] S201: Obtain the vehicle status, vehicle location, and predetermined route of the vehicle, as well as road conditions, traffic conditions, and weather conditions of the road section on the predetermined route.

[0050] That is to say, obtain the current vehicle status, vehicle location, predetermined route of the vehicle through various means, as well as road conditions, traffic conditions, and road conditions of sections within a certain range (such as within L meters of the vehicle position) on the route of the vehicle’s expected form. Weather conditions to use them to judge driving risks.

[0051] Among...

Embodiment 3

[0083] Such as Figure 4 As shown, this embodiment provides a driving risk warning device, which includes:

[0084] The acquiring unit is used to acquire the vehicle status, vehicle location, predetermined route, and road conditions, traffic conditions, and weather conditions of the road section on the predetermined route;

[0085] The analysis unit is used to classify corresponding road sections as high-risk road sections or low-risk road sections with a pre-established BP network according to vehicle conditions, road conditions, traffic conditions, and weather conditions;

[0086] The warning unit is used to send warning information to the vehicle to control the vehicle to issue a warning when driving to a high-risk road section.

[0087] The driving risk warning device of this embodiment can execute the above method, so that a warning can be issued when the vehicle is driving to a high-risk road section to remind the driver to pay attention, thereby reducing the possibility of accid...

Abstract

The invention provides a driving risk warning method and a driving risk warning device, which belong to the technical field of assist driving, and can at least partially solve the problem that a high-risk road section cannot be alerted in the prior art. The driving risk warning method comprises the steps of: acquiring a vehicle condition, a vehicle position and a predetermined route of a vehicle,and acquiring road conditions, traffic conditions and weather conditions of road sections on the predetermined route; classifying the corresponding road sections into high-risk road sections or low-risk road sections by utilizing a pre-established BP network according to the vehicle condition, the road conditions, the traffic conditions and the weather conditions; and sending warning information to the vehicle, so as to control the vehicle to send out warning when the vehicle drives to the high-risk road sections.

Description

Technical field [0001] The invention belongs to the technical field of assisted driving, and specifically relates to a driving risk warning method and device. Background technique [0002] During the driving of the vehicle, due to the different road conditions and weather of different road sections, the possibility of traffic accidents is also different, that is, some road sections have a high risk, and some road sections have a low risk. On high-risk road sections, drivers are particularly required to concentrate in order to reduce the probability of accidents. For example, listening to music played by the on-board audio system during driving is a habit of many drivers. It can relieve fatigue and increase fun. However, if you continue to listen to music on high-risk roads, it will distract the driver and increase the incidence. The possibility of an accident. [0003] It can be seen that the prior art cannot remind drivers to concentrate on high-risk road sections, which will af...
