Problems solved by technology

Pedestrian recognition mainly uses sensors such as monocular or binocular cameras and multi-line lidar. Through feature extraction, the features are used as the input for classification, and the supervised learning algorithm is used for classification learning. Its classification ability is good, but its ability to identify motion parameters is poor.
The pedestrian behavior cognition method mainly builds a cognitive model through the Markov theory, which is mainly aimed at the pedestrian itself, without considering the interaction between vehicles and pedestrians.
The research on the pedestrian protection system is mainly on the pedestrian recognition method, lack of research on the pedestrian behavior cognition method, comprehensively consider the research on pedestrian recognition and behavior cognition methods, and do not further consider the impact of pedestrian recognition and behavior cognition results on vehicles. impact of decision
[0004] At this stage, for autonomous driving technology, pedestrian recognition and behavior cognition have the following problems: 1) Unable to autonomously recognize and learn and pre

Abstract

The invention discloses a vehicle speed control device and method. The vehicle speed control device comprises an environment sensing and integration module, a pedestrian jaywalking behavior cognition module and an automatic driving decision-making module, wherein the environment sensing and integration module is used for detecting the information of a jaywalking pedestrian in front of a running vehicle and outputting the information of the jaywalking pedestrian; the pedestrian jaywalking behavior cognition module is used for receiving the information of the jaywalking pedestrian and outputting the pedestrian's behavior cognition information according to the received information of the jaywalking pedestrian combined with the dynamic time series information and the interaction between the vehicle and the pedestrian; and the automatic driving decision-making module is used for receiving environment information and pedestrian's behavior cognition parameters, giving the current traffic speed of the vehicle, and outputting the current traffic speed of the vehicle. According to the vehicle speed control device and method disclosed by the invention, in the running process of the vehicle, the pedestrian target in front of the vehicle can be accurately recognized, the pedestrian's intention can be predicted, real-time judgment is performed, reasonable decision can be made, and autonomous recognition and decision-making of an autonomous vehicle can be realized when a pedestrian crosses the road, so that the vehicle can safely and smoothly give way to the pedestrian crossing the road.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a vehicle speed control device and method. Background technique [0002] Self-driving vehicles realize autonomous driving through technologies such as environmental perception, cognition, decision-making, and vehicle control. Self-driving vehicles have a positive effect on traffic safety, traffic efficiency, environmental protection and energy saving. Governments and road-related operators around the world are increasingly interested in self-driving cars, hoping that self-driving cars can make road traffic safer, more efficient and more environmentally friendly. Self-driving vehicles improve the reaction speed to the traffic environment by autonomously sensing the environment, cognition, decision-making and control, and quickly perform corresponding operations in different scenarios, including dangerous scenarios, such as braking and steering, thereby improving traffic safety. ...
