Abstract

The invention discloses a system for testing the parking response time. The system comprises a mobile test part, a trigger part and a signal receiver. A first electric signal emitted by the trigger part triggered by the alarm point of a tested vehicle when the mobile test part passes through and a second electric signal emitted by the sound output part of the tested vehicle when an alarm sound isemitted are obtained through the signal receiver, and the electric signals are used for replacing sound signals, so the propagation delay is greatly reduced; the signal receiver is used for replacinga camera and a microphone to measure the parking response time, so the equipment error is greatly reduced, and the millisecond-level unit response time required in ISO related standards can be very accurately measured; and special devices such as the camera / microphone and analysis using audio and video processing software are not needed in the test process, so that the test specialty is reduced, and the test cost is reduced. The invention further discloses a method for testing the parking response 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...
