Embodiment Construction

[0058] In order to enable those skilled in the art to better understand the technical solution of the present invention, the vehicle speed control method and device proposed by the present invention will be described in detail below with reference to the accompanying drawings.

[0059] figure 1 It is a flow chart of the first embodiment of the vehicle speed control method provided by the present invention. like figure 1 As shown, the specific work flow of the first embodiment of the vehicle speed control method provided by the present invention includes the following steps:

[0060] Step 101, obtaining the steering angle of the steering wheel of the car.

[0061] When the car runs on a curve and turns, the steering angle of the steering wheel can be collected by the angle sensor installed on the steering wheel, and after the steering angle of the steering wheel is collected, go to step 102 .

[0062] Step 102, judging whether the steering angle of the steering wheel is with...

Abstract

The invention provides a vehicle running speed control method and a device thereof. The method comprises the steps of: obtaining a steering angle of a vehicle steering wheel; judging whether the steering angle of the vehicle steering wheel is within a preset steering range; and controlling a vehicle to run according to a preset speed which corresponds to the steering angle within the preset steering range when the steering angle is arranged within the preset steering angle range. In the embodiment of the invention, the vehicle is controlled to run according to the preset speed within the preset steering range when the steering angle of the vehicle steering wheel is arranged within the preset steering range, so that the vehicle can be accurately and timely controlled to run according to the preset speed on the basis of the steering angle and the road gradient when the vehicle is steered, and the danger when the vehicle steers at a overspeed can be avoided. In the embodiment of the invention, the vehicle running speed control method is simple and easy to realize, and can be effectively avoid the lateral turning or the lateral sliding when the vehicle steers, so that the safety of a driver and the vehicle can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a method and device for controlling the driving speed of an automobile. Background technique [0002] When the vehicle is running on a curve or turning, the vehicle control system installed on the car realizes the corresponding curve driving or steering operation by controlling the rotation angle of the steering wheel. When the radius of the curve or the turning radius is large, the steering wheel is controlled to turn through a relatively large angle; correspondingly, when the radius of the turning or the turning radius is small, the steering wheel is controlled to turn through a small angle. [0003] In the actual driving process, if the radius of the curve or the turning radius is too large, it is necessary to turn the steering wheel in a large range to obtain a larger steering wheel steering angle. There is a risk of the vehicle skidding or rolling over. Therefor...
