A method and apparatus for speed control of a vehicle

Abstract

The embodiment of the present application discloses a vehicle speed control system and a corresponding method, for speed control of a vehicle in response to a stationary object. The speed control system comprises an environmental parameter sensor, a target detection sensor, a processor and a controller. The processor is configured to determine object information in front of the vehicle based on asignal of the target detection sensor, determine a stationary object in front of the vehicle, and determine that the stationary object is a target object for speed control according to vehicle currentroad condition information determined by a signal of an environmental parameter sensor and object information of the stationary object in front of the vehicle. As the current road condition of the vehicle is taken into consideration when judging the stationary object, the accuracy of judging the stationary object of the vehicle under the special road condition is improved.

Description

technical field [0001] The present application relates to the field of automobiles, in particular to a technology for controlling the speed of automobiles. Background technique [0002] With the development of automotive technology, assisted driving technology and autonomous driving technology have more applications. In this type of technology, the car can automatically control the speed of the car or alert the driver based on the detected object, thereby improving the safety of the car and the driving experience. For example, the Adaptive Cruise Control (ACC) system can control the speed of the car to match the target in front of the vehicle according to the target in front of the vehicle, so that the vehicle can automatically adjust the cruising speed during the process of cruising, thereby reducing the driver's operation to enhance the driving experience. For another example, the Vehicle collision warning system (Vehicle collision warning system)\Vehicle automatic bump-...

AI Technical Summary

Problems solved by technology

For the identification of this type of stationary target, in the prior art, in order to avoid false triggers caused by incorrectly identifying stationary objects as stationary targets, some assisted / automatic driving technologies do not respond to stationary targets, although this reduces false triggers, However, it has a certain impact on driving safety

Other assisted / automatic driving technologies use image recognition technology to identify stationary objects to determine whether the stationary object is a stationary target for speed control. However, the accuracy of this type of recognition technology is still not high, and misjudgment is prone to occur. Affect the driving experience
