A smart vehicle motion control method for protecting human-ground collision damage

Abstract

The invention proposes a motion control method of an intelligent vehicle for protecting human-earth collision damage. When it is detected that the accident is inevitable, the vehicle is fully braked until the moment t1 when the human head collides with the vehicle body for the first time; then release the vehicle brake and monitor the speed of the human chest in the x and y directions in real time, and calculate x and y respectively The difference between human speed and vehicle speed in the direction e1 and e2; longitudinal motion control is performed according to e1, and lateral motion control is performed according to e2 only when the person and vehicle are out of contact; when it is detected that the human body is about to fall to the ground, the vehicle is fully braked to avoid rolling pressure. The beneficial effects of the present invention are: through the control of the lateral and longitudinal movement of the vehicle, it is ensured that the human body can fall onto the vehicle body and then fall to the ground, so that the moving vehicle can affect the landing posture of the human body, thereby protecting the human body from collision damage.

Description

technical field [0001] The invention relates to the field of smart cars, more specifically, to a smart car motion control method for protecting people from collision damage. Background technique [0002] From the beginning of its conception, smart cars have assumed people's good wishes for road traffic safety, intelligence, high efficiency, energy saving and environmental protection. People expect that through smart cars, the number of traffic accidents will be greatly reduced and the vision of zero accidents will be realized. Pedestrian-vehicle collision accidents are a very common form of accidents in all traffic accidents. The unpredictability of humans makes it difficult for smart cars to fully identify potential risks and take effective measures to prevent such accidents. In the era of intelligence, it is certain that the number of accidents will decrease significantly, and the speed of collisions will also decrease significantly. However, from the current mining of acc...

[0005] Aiming at the fact that the existing intelligent vehicle motion control method for protecting human-ground collision damage does not control the lateral movement of the vehicle, the present invention proposes a smart vehicle motion control method for protecting human-ground collision damage. Differentially control the longitudinal motion of the vehicle to ensure that the speed of the vehicle is consistent, and control the lateral motion of the vehicle after the vehicle is out of contact according to the lateral speed difference between the human and the vehicle to ensure that the kinetic energy obtained by the human body from the vehicle body is not increased during the entire process, thereby increasing the risk of human-ground collision damage According to this, the purpose of affecting the posture of the human body falling to the ground by moving the vehicle, and then protecting the human body from collision damage, the implementation steps are as follows:
