Problems solved by technology

[0002] With the development of automobile intelligent technology, automatic parking technology is becoming more and more mature. One of the core algorithms of automatic parking technology is speed control. At present, the speed calculation of the existing technology mainly relies on the sensors installed around the vehicle to measure the body and its surroundings. The distance and angle between the environment, the vehicle speed is calculated by collecting sensor data, but the vehicle speed calculated by the existing technology is a constant value, and only the influence of the initial remaining distance on the vehicle speed is considered, resulting in a low accuracy rate of vehicle speed control
[0003] For the above problems, no effective solution has been proposed

Abstract

The invention discloses a vehicle speed control method. The method comprises the steps that obstacle information sensed by a sensor installed on a current vehicle and path information of the current vehicle are obtained, the obstacle information at least comprises the first distance between the current vehicle and an obstacle, and the path information comprises the second distance between the current vehicle and a target position; the path curvature of the current vehicle driving road and the deviation error between the current vehicle and the target position; a vehicle speed of the current vehicle is determined based on the obstacle information and the path information. The technical problem that the control accuracy of the vehicle speed is low in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of intelligent vehicles, in particular to a method for controlling vehicle speed. Background technique [0002] With the development of automobile intelligent technology, automatic parking technology is also becoming more and more mature. One of the core algorithms of automatic parking technology is speed control. The current speed calculation of the existing technology mainly relies on the sensors mounted around the vehicle to measure the body and surrounding areas. However, the vehicle speed calculated by the prior art is a constant value, and only the influence of the initial remaining distance on the vehicle speed is considered, resulting in a low accuracy rate of the vehicle speed control. . [0003] For the above problems, no effective solution has been proposed yet. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a method for controlling vehicle speed, so as to at leas...
