AI Technical Summary

Technical Problem

Existing technologies are insufficient in accurately predicting a vehicle's specific driving trajectory, especially its specific outline and wheel trajectory, and in issuing timely and effective warnings to surrounding vehicles and pedestrians when the driver is in an abnormal state, and are unable to effectively reduce the probability of traffic accidents.

Method used

By collecting steering wheel angle and wheel speed information in real time, the vehicle's driving trajectory in the short term is predicted, and the trajectory is projected onto the road using projection lights in front and behind the vehicle to remind surrounding vehicles and pedestrians to avoid it.

Benefits of technology

It achieves an intuitive presentation of the vehicle's driving space in the next few seconds, significantly reduces the risk of collision, improves the accuracy and safety of prediction, reduces system costs, and provides stable projection applications in complex environments.

Abstract

The invention provides a vehicle driving track predicting and reminding method and system, a storage medium and a vehicle. The method comprises the following steps that the positions of four wheels of the vehicle in a future preset short time are predicted based on the current steering wheel rotating angle and the current wheel rotating speed; based on the predicted positions of the four wheels of the vehicle, generating a shadow position covered by the vehicle on the road surface in a future preset short time as a driving track; and projecting the predicted driving track to a road surface through projection lamps arranged around the vehicle so as to remind surrounding vehicles and pedestrians to avoid. According to the invention, the driving track of the vehicle in a short time in the future can be predicted through the information such as the wheel speed and the steering wheel angle collected in real time, and the predicted driving track is projected to the road surface through the ground projection lamps arranged in front of and behind the vehicle, so that surrounding vehicles and people are reminded, and traffic accidents are reduced.
