Embodiment Construction
[0037] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the application more thorough and comprehensive.
[0038] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention relates to a vehicle-pedestrian collision risk domain calculation method and a safety evaluation system. The method for determining the collision risk domain between the vehicle and thepedestrian comprises the following steps: detecting and outputting vehicle information and pedestrian information; and judging whether the pedestrian notices the vehicle; and under the condition thatthe pedestrian adopts the active avoidance behavior and the pedestrian does not adopt the active avoidance behavior, further assuming whether the vehicle adopts an instant reaction action or not, anddetermining a collision risk domain between the vehicle and the pedestrian according to a hypothesis result of whether the pedestrian adopts an active avoidance behavior and whether the vehicle adoptsan instant reaction action. According to the method for determining the collision risk domain between the vehicle and the pedestrian, the active avoidance capability of the pedestrian and the instantresponse action of the vehicle are considered at the same time, so that the collision risk between the vehicle and the pedestrian can be identified more fully. According to the method, the effectivecollision risk domain is determined, and the pedestrian safety and the vehicle driving comfort in the vehicle and pedestrian interaction process can be effectively improved.
Description
technical field [0001] The present application relates to the technical field of automobile safety, in particular to a calculation method and a safety evaluation system of a vehicle-pedestrian collision risk domain. Background technique [0002] With the development of automobile autonomous driving technology, the technology for vehicle safety is becoming more and more mature, such as the relatively mature automobile active safety technology at present. At present, there is an automatic emergency braking system (English full name Autonomous Emergency Braking, referred to as AEB system) based on automobile active safety technology. The AEB system mainly includes three modules: control module (ECU), ranging module and braking module. The core of the ranging module includes microwave radar, face recognition technology and video system, which can provide safe, accurate and real-time images and road condition information of the road ahead. The AEB system can detect dangerous wo...
