Simulation apparatus and simulation method for AEBS test

Abstract

The invention provides a simulation apparatus and simulation method for an AEBS test. The simulation apparatus comprises a mobile target vehicle arranged at the front side of a tested vehicle, a traction automobile arranged at the side of the mobile target vehicle, and a draw bar. One end of the draw bar is hinged to the side of the traction automobile and the other end of the draw bar is connected with the mobile target vehicle by an electromagnetic actuation device. The apparatus has advantages of simple structure, low cost, small size, and high maneuverability; and the driving vehicle speed is high and the test field requirement is low. After collision, the driving channel of the tested vehicle is broad and security is high. The mobile target vehicle bonding with the tested vehicle moves forwardly after collision, so that the moving track of the mobile target vehicle can be controlled effectively and the impact force between the mobile target vehicle and the tested vehicle can be reduced. In addition, the invention also provides a simulation method for AEBS test by using the simulation apparatus.

Description

technical field [0001] The invention relates to a simulation device and simulation method for AEBS test. Background technique [0002] In order to prevent car rear-end collisions and improve the active safety performance of cars, more and more cars are beginning to install Active Emergency Braking System (AEBS), which is a road vehicle safety system that brakes autonomously. The system monitors the vehicle in front by sensors. It also detects the relative speed and distance between the vehicle and the target vehicle, calculates the imminent situation, and warns the driver to take measures or automatically emergency brake in dangerous situations to avoid a collision or mitigate the hazard of a collision. Studies have shown that if all cars are equipped with this system, the traffic accident rate will be reduced by 27%. [0003] At present, the European Union has mandated that M2, M3, N2, and N3 vehicles be installed with active emergency braking systems (AEBS), and has formu...

Problems solved by technology

The first scheme is small in size, good in maneuverability and high in safety, but has a complex structure and high cost. The second scheme is slightly lower in cost, but has the following defects: In order to prevent the test vehicle from colliding with the front towing vehicle, the It needs a traction device with a length of more than 30m, the overall structure is huge, and it is inconvenient to install and connect; the driving stability is poor, and it can only be driven at a low speed; the turning is inconvenient, and the requirements for the test site are harsh. The wheels are easy to scratch or crush with the traction device, causing the danger of the tractor overturning
