Embodiment 1

[0044] Test and evaluation system for commercial vehicle automatic emergency braking system, such as figure 2 Shown: including fixed base station, positioning module, collection module, processing module, moving target module and scoring module.

[0045]The fixed base station module is located at one side of the test lane. The fixed base station module is used to receive the positioning signal and calculate the ground position and send it to the processing module. The fixed base station module includes the first GPS antenna for receiving GPS signals, the first Radio antenna for correction and the transceiver unit The positioning module is located on the test vehicle, and the positioning module acquires the positioning information and the real-time speed of the test vehicles traveling towards the test targets in various test scenarios under preset conditions, and sends them to the processing module. The positioning module includes receiving The second GPS antenna for GPS signa...

Abstract

The invention relates to the technical field of vehicle testing, in particular to a testing and evaluating system and method for an automatic emergency braking system of a commercial vehicle, and the system comprises a fixed base station, a positioning module, an acquisition module, a processing module, a moving target module and a scoring module. The method comprises the steps o: enabling a test vehicle to drive towards a test target in a test scene under a preset condition, detecting the real-time position and the real-time speed of the test vehicle, judging whether the test vehicle reaches a preset position or not according to the real-time position, and starting test when the test vehicle reaches the preset position; testing for a preset number of times according to a preset condition; detecting identification information and braking information of the automatic emergency braking system on the test vehicle to the test target, ending the test when the test vehicle meets an ending condition, and forming a test result according to the identification information, the braking information and the real-time speed; and scoring the test result according to the test target to obtain an evaluation score. The multi-dimensional evaluation improves the evaluation accuracy.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a testing and evaluation system and method for an automatic emergency braking system of a commercial vehicle. Background technique [0002] Due to the large size and heavy weight of commercial vehicles, when a collision accident is about to occur in front of the vehicle during driving, whether the commercial vehicle can perform emergency braking in time is related to whether the collision accident can be controlled and avoided in time. Therefore, The demand for vehicle driving assistance systems is becoming more and more urgent. For example, in order to address safety issues under emergency braking conditions, commercial vehicles should also be equipped with automatic emergency braking systems. [0003] After the automatic emergency braking system is installed on the commercial vehicle, in order to verify the effectiveness of the automatic emergency braking system and eva...
