Abstract

The application discloses a test system for parking reaction time, which includes a mobile test component, a trigger component and a signal receiver. The first electrical signal, and the second electrical signal sent by the sound output part of the vehicle under test when the alarm sound is issued, because the electrical signal is used instead of the sound signal, the propagation delay is greatly reduced, and the signal receiver is used instead of the camera and the microphone pair The error of the equipment is greatly reduced by measuring the parking reaction time, and the reaction time in millisecond units required by the relevant ISO standards can be measured very accurately. In addition, during the test, there is no need for professional equipment such as cameras / microphones, and no need for special audio and video processing software for analysis, which reduces test professionalism and test costs. The application also discloses a method for testing the parking reaction time.

Description

technical field [0001] The present application relates to the technical field of vehicle electronics, in particular to a test system and a corresponding test method for the response time of a parking assistance system. Background technique [0002] Along with the development of science and technology, vehicle has become comparatively popular means of transportation. Human beings have higher and higher requirements for vehicle safety, especially when parking, the vehicle needs to be able to detect obstacles in time, and provide an alarm message to the driver when the obstacle reaches a certain position to remind the driver. The International Standardization Organization (ISO) 17386-2004 stipulates that "when the system is activated, the time delay from the appearance of obstacles within any range to the warning message to the driver should not exceed 350ms". Therefore, it is necessary to detect the reaction time of the parking assistance system, that is, the parking reaction...
