Description

Technical Field

[0001] The present invention relates to the technical field of blind spot monitoring, and in particular to a monitoring system and method for blind spots of new energy vehicles. Background Art

[0002] With the rapid development of intelligent network technology, in-depth exploration of vehicle blind spots and continuous optimization and upgrading of blind spot monitoring technology have become the core issues and key scientific research directions in the field of driving safety at present and in the future. The progress in this field is not only related to technological innovation, but also directly related to the safety of life and property of road users, and is an indispensable part of the construction of intelligent transportation systems.

[0003] The extensive practice and in-depth application of autonomous driving technology are leading the automotive industry into an unprecedented era of change. In order to achieve safe driving of vehicles in complex and changing road environments, we must comprehensively and deeply analyze the potential risks of vehicles in various extreme and complex scenarios to ensure all-weather and all-round safety during driving. This requires us to make continuous breakthroughs in technology, especially in the field of blind spot monitoring, to achieve all-angle monitoring of the vehicle's surroundings, timely warn of potential dangers, and effectively prevent the occurrence of traffic accidents. In this context, a monitoring system and method for blind spots of new energy vehicles is particularly important.

[0004] At present, although vehicle blind spot monitoring technology has made significant progress, it is still difficult to cover some blind spots due to the physical characteristics and detection range of sensors, which poses a potential threat to driving safety. Especially in complex and changing road environments, such as near pedestrian intersections or on mountain road bends, pedestrians or obstacles may be blocked by other vehicles, buildings or terrain and are out of the detection range of ordinary cameras and radars.

[0005] Specifically, when a pedestrian suddenly jumps out from in front of a vehicle at a pedestrian crossing, traditional cameras and radar systems often have difficulty capturing this dangerous situation in advance due to obstructions by the vehicle itself, parked vehicles on the roadside, or other obstacles, causing the driver to be unable to respond in time, increasing the risk of collision. Similarly, at bends on mountain roads, due to the curvature of the bend and the limitations of the terrain, the radar beam and camera line of sight may be blocked by mountains, trees, or buildings, leaving pedestrians or other potential obstacles in the detection blind spot, seriously threatening the safety of road users. These problems not only affect the safety and comfort of the driver, but also pose a challenge to the protection of pedestrians. These problems not only affect the safety and comfort of the driver, but also pose a challenge to the protection of pedestrians. Summary of the invention

A monitoring method applied to the monitoring system for blind spots of new energy vehicles as claimed in any one of claims 1 to 8, characterized in that: include: Acquire environmental information around the vehicle, road information in front of the vehicle, and mobile heat source information in front of the vehicle; Processing environmental information, information about the road ahead of the vehicle, and information about mobile heat sources to identify whether there is a blind spot, whether there is a mobile heat source in the blind spot, and whether there is a risk of collision with the heat source, thereby obtaining warning information; the warning information includes blind spot prompt information, heat source prompt information, and collision prompt information; Based on the warning information, the driver is warned.

10. The monitoring method according to claim 9, characterized in that: The environmental information, the road information ahead of the vehicle and the mobile heat source information are processed to identify whether there is a blind spot, whether there is a mobile heat source in the blind spot and whether there is a heat source collision risk, so as to obtain warning information, including: Identify environmental information, determine whether there is a blind spot on the road ahead, and obtain blind spot prompt information; When there is a blind spot in the road ahead, the mobile heat source information is processed to determine whether there is a mobile heat source in the blind spot and obtain heat source prompt information; When there is a moving heat source in the blind spot, the road information in front of the vehicle and the moving heat source information are processed to determine whether there is a heat source collision risk and obtain collision prompt information; The process of processing the road information ahead of the vehicle and the mobile heat source information includes: Based on the road information ahead of the vehicle and the mobile heat source information, the vehicle's driving trajectory and speed and the trajectory and speed of the mobile heat source are obtained; Calculate the collision point between the moving heat source and the vehicle according to the vehicle's driving trajectory and the moving heat source's trajectory; According to the speed of the vehicle, the distance from the vehicle to the collision point, the speed of the mobile heat source and the distance from the mobile heat source to the collision point, the time T1 when the vehicle travels to the collision point and the time T2 when the mobile heat source arrives at the collision point are calculated; wherein the distance from the vehicle to the collision point and the speed of the vehicle are obtained through the road information in front of the vehicle, and the distance from the mobile heat source to the collision point is obtained through the mobile heat source information; When the absolute value of the difference between T1 and T2 does not exceed the collision threshold, it is determined that there is a thermal source collision risk on the road ahead, and a collision prompt message "There is a thermal source collision risk at present, please stop and wait" is generated; When the absolute value of the difference between T1 and T2 exceeds the collision threshold, it is judged that there is no collision risk on the road ahead, and a collision prompt message "There is currently no thermal source collision risk, and you can drive normally" is generated.
