Problems solved by technology

[0004] The biggest disadvantage of this test platform is that the arm of the pedestrian model cannot swing naturally and cannot simulate the walking characteristics of real pedestrians. However, the pedestrian AEB system evaluation criteria obtained based on the pedestrian model with a fixed posture makes the pedestrian AEB system only suitable for protecting pedestrian models. Can't protect real pedestrians well

Abstract

The invention discloses a pedestrian AEB (Autonomous Emergency Braking) system test platform. The platform comprises a pedestrian module, a first control module and a second control module; the pedestrian module includes a pedestrian model and a swing arm control module; the swing arm control module is used for controlling the swing of the arms of the pedestrian model; the first control module isused for pulling a test vehicle to move along a first path according to first motion parameters, and activating the second control module according to preset collision parameters; and the second control module is used for pulling the pedestrian model to move along a second path with a second movement state according to second motion parameters. According to the pedestrian AEB (Autonomous EmergencyBraking) system test platform of the invention, the arm swing action design of the pedestrian model is realized, and various walking postures of a real pedestrian can be simulated. Compared with a traditional posture-fixed pedestrian model, the pedestrian model of the platform can improve biological simulation degree and is closer to the real pedestrian. Test results of the test platform can provide a more accurate pedestrian protection design basis for a pedestrian AEB (Autonomous Emergency Braking) system.

Description

technical field [0001] The invention relates to the technical field of Advanced Driver Assistant System (ADAS), in particular to a pedestrian AEB system test platform. Background technique [0002] The Automatic Emergency Braking (AEB, Autonomous Emergency Braking) system is an autonomous and automatic road vehicle safety system. The system relies on sensors to monitor the target in front and detect the relative speed and distance to the target, calculate the situation that is about to happen, and Emergency braking is automatically applied in dangerous situations to avoid or mitigate collisions. In other words, AEB is an active safety system that automatically applies emergency braking under dangerous driving conditions. According to the different targets, the AEB system is divided into three categories: vehicles, people, and two-wheeled vehicles. Euro NCAP (EU New Car Certification Program / Center) divides the AEB system into urban AEB system, intercity AEB system and pede...
