Problems solved by technology

However, after a period of use and natural aging, the use of the anti-splash device is getting worse and worse
As a result, the possibility of water splashing on pedestrians when the vehicle passes through the water-logged road surface is increased, and the conflict between vehicles and pedestrians becomes increasingly prominent, which reduces driving safety.

Embodiment 1

[0036] figure 1 It is a flow chart showing a vehicle running control method according to Embodiment 1 of the present invention. available in as Figure 4 The method is executed on the vehicle travel control device shown.

[0037] refer to figure 1 , in step S110, detecting whether there is water accumulation on the road surface along the traveling direction of the vehicle.

[0038] In a specific implementation manner, equipment such as an image sensor installed in front of the vehicle can be used to collect image information of the road surface in the direction of vehicle travel, and then the collected image information is processed using existing image processing technology. As a result, it can be judged whether there is standing water on the road ahead.

[0039] In step S120, if it is detected that there is accumulated water on the road surface along the traveling direction of the vehicle, the vertical distance between the vehicle and surrounding pedestrians along the tr...

Embodiment 2

[0046] image 3 is a flow chart showing a vehicle driving control method according to Embodiment 2 of the present invention, and the embodiment can be regarded as figure 1 Another specific implementation scheme of . available in as Figure 5 The method is executed on the vehicle travel control device shown.

[0047] refer to image 3 , in step S210, detecting whether there is water accumulation on the road surface along the traveling direction of the vehicle.

[0048] Here, the processing method of this step is the same as that of step S110 in the first embodiment, for details, please refer to the content of step S110 above, which will not be repeated here.

[0049] Wherein, steps S220 and S230 may be refinements of step 120 in the first embodiment above, specifically as follows:

[0050]In step S220, if it is detected that there is accumulated water on the road surface along the traveling direction of the vehicle, the linear distance between the surrounding pedestrians a...

Embodiment 3

[0080] Based on the same technical idea, Figure 4 is a logic block diagram showing the vehicle travel control device according to the third embodiment of the present invention. It can be used to execute the flow of the vehicle driving control method described in the first embodiment.

[0081] refer to Figure 4 , the vehicle travel control device includes: a water accumulation detection module 310 , a vertical distance acquisition module 320 , a travel speed acquisition module 330 and a travel speed control module 340 .

[0082] The accumulated water detection module 310 is used to detect whether there is accumulated water on the road surface along the traveling direction of the vehicle.

[0083] The vertical distance acquisition module 320 is configured to acquire the vertical distance between the vehicle and surrounding pedestrians along the vehicle's traveling direction if it is detected that there is accumulated water on the road surface along the vehicle's traveling di...

Abstract

The present invention provides a vehicle running control method and device. The vehicle running control method comprises: detecting whether water exists on a pavement in the running direction of a vehicle; if detecting that water exists on the pavement along the running direction of the vehicle, obtaining the vertical distance between the vehicle in the running direction of the vehicle and pedestrians around; acquiring a safety running speed for preventing splashing according to the value of the vertical distance; and controlling the vehicle to run according to the safety running speed. By applying the vehicle running control method and device provided by the embodiments of the invention, the vehicle is controlled to safely pass the pavement with water, the conflict between the vehicle and pedestrians is effectively prevented, and the running safety is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular to a vehicle driving control method and device. Background technique [0002] With the development of society, people's living standards are gradually improving, and the number of vehicles in cities is increasing day by day. While vehicles bring convenience to people's lives, they also bring some disadvantages. For example, in rainy days, vehicles often drive across the road surface with water, splashing water on pedestrians. Moreover, the more accumulated water, the higher the speed of the vehicle, and the farther the splash distance will be. [0003] At present, the prior art is usually to install the anti-splash device at the vehicle tire place. However, after a period of use and natural aging, the use effect of the splash-proof device is getting worse and worse. As a result, the possibility of water splashing to pedestrians when the vehicle passes through the...
