A Pedestrian Detection and Active Collision Avoidance Method in the Blind Spot of Intelligent Vehicle Sensor

Abstract

The invention discloses a pedestrian detection and active collision avoidance method in the blind area of ​​an intelligent car sensor. The vehicle-mounted sensor obtains the driving state information during the driving process of the intelligent car, and at the same time obtains the sensor blind area information, detects whether a pedestrian enters the sensor blind area, and passes the vehicle-mounted sensor. Collect the pedestrian status information at the moment A when the pedestrian is at the boundary of the sensor blind zone, such as speed, acceleration, position information, etc., use the Kalman filter to optimize the collected pedestrian status information, and predict when the pedestrian moves to the sensor blind zone boundary through correlation calculations When B, whether the smart car is in a dangerous area, judge whether it needs to actively avoid collision in advance according to the prediction result. Smart cars will actively avoid dangerous collision conditions that may be caused by the existence of sensor blind spots during driving, and are safer when passing through sensor blind spots, thus effectively improving the performance of the active safety system of smart cars and the driving safety of vehicles.

Description

technical field [0001] The invention relates to a pedestrian detection and active collision avoidance method in the blind area of ​​an intelligent automobile sensor, belonging to the technical field of driving safety. Background technique [0002] In recent years, with the development of science and technology, smart cars have gradually come into our sight. Smart cars sense the road environment through on-board sensing systems, automatically plan driving routes and control vehicles to reach predetermined targets. It uses on-board sensors to perceive the surrounding environment of the vehicle, and controls the steering and speed of the vehicle based on the road, vehicle position and obstacle information obtained from the perception, so that the vehicle can drive safely and reliably on the road. Advanced vehicle active safety systems remain a top priority in smart vehicle technology research. In most road environments where people and vehicles are mixed, due to the obstructi...
