Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0065] Such as figure 1 As shown, in one embodiment, a method for controlling vehicle following speed is proposed, the method comprising:

[0066] Step 102, acquiring the speed of the preceding vehicle, the speed of the own vehicle, and the current distance between the preceding vehicle and the own vehicle.

[0067] Among them, the vehicle in front (also known as "leading vehicle in front") refers to the vehicle in front that is in the same lane as the vehicle and is closest to the vehicle. This vehicle refers to the vehicle currently being charged, that is, one's own vehicle. The speed of the v...

Abstract

The invention provides a vehicle following speed control method. The method includes the steps that the front vehicle speed, the own vehicle speed and the current vehicle distance between a front vehicle and an own vehicle are obtained, the corresponding target vehicle following distance is calculated according to the front vehicle speed and the own vehicle speed, the first accelerated speed is obtained through calculation according to the current vehicle distance, the target vehicle following distance, the front vehicle speed and the own vehicle speed, a stable interval range is obtained, thetarget accelerated speed is determined according to the first accelerated speed and the stable interval range, and the traveling speed of the own vehicle is controlled according to the target accelerated speed. By the adoption of the method, the vehicle travels stably within a certain range, frequent acceleration and deceleration switchovers are avoided, and the comfort level and stability are improved. In addition, the invention provides a vehicle following speed control device and system, computer equipment and a storage medium.

Description

technical field [0001] The present invention relates to the field of computer processing, in particular to a following speed control method, device, system, computer equipment and storage medium. Background technique [0002] With the growth of the economy, the number of cars is increasing rapidly, and urban traffic congestion is becoming more and more serious. When the vehicle is driving, it needs to maintain an appropriate safe distance from the vehicle in front. If the speed of the vehicle in front changes, the vehicle also needs to adjust the speed at any time. , which requires the driver to be highly concentrated and brings tremendous mental pressure to the driver. [0003] There are two traditional ways to solve this kind of problem, one is to install FCWS (Forward CollisionWarning System, Forward Collision Warning System), FCWS can detect the vehicle in front and warn the driver when there is a collision risk, but it does not itself Any braking measures will be used ...
