Testing system and method

Abstract

The embodiment of the invention provides a testing system and method. The testing system comprises an upper computer, an ADAS test rack and a tested controller. The upper computer is used for receiving test parameters input by input equipment, generating a control instruction according to the test parameters and sending the control instruction to the tested controller. The ADAS test rack is used for generating a controlled object simulating model, and a tested virtual vehicle is obtained through joint constructing of the controlled object simulating model and the tested controller. The testedcontroller is used for receiving the control instruction sent by the upper computer and controlling the virtual vehicle to complete virtual test aiming at an ADAS function system according to the control instruction. When the testing system and method are applied for testing, testing can be conducted through the mode of combination of the virtual vehicle, the virtual scene and the real controller,consumption of manpower and material resources is greatly lowered, and meanwhile, the influence on personal safety and the vehicle loss in the real vehicle testing process is avoided.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a testing system and testing method. Background technique [0002] With the development of automobile technology, more and more vehicles are equipped with ADAS (Advanced Driver Assistance Systems, advanced driver assistance system), among which, ADAS usually includes navigation and real-time traffic system, electronic police system, car networking, adaptive cruise, Lane departure warning system, lane keeping system, collision avoidance or pre-collision system, night vision system, adaptive light control, pedestrian protection system, automatic parking system, traffic sign recognition, blind spot detection, driver fatigue detection, downhill control system And functional systems such as electric vehicle alarm systems. [0003] In order to ensure the reliability of ADAS, it is often necessary to perform functional tests on the controllers of each functional system in ADAS before l...

Problems solved by technology

During the test, if the function of the controller fails to pass the test, the control logic of the controller needs to be modified, and this process often requires constant communication between the OEM and the supplier and repeated modification tests. As far as the road test program is concerned, this is very labor-intensive and materially resource-intensive; moreover, when the controller under test fails, it is easy to cause danger to the test personnel and damage to the test vehicle
