Problems solved by technology

Since the lane change of the vehicle must be completed during the driving process, and the vehicle is in the lane at this time, the driving of other vehicles will inevitably affect the lane change of the vehicle, and even cause traffic accidents.

Embodiment 1

[0040] A method for testing and evaluating a vehicle active lane change system, such as figure 1 As shown, it includes preparation steps, detection area test steps, lane change test steps and evaluation steps. Preparatory steps: Select two vehicles, which are respectively defined as the test vehicle and the background vehicle. The active lane change system to be tested is equipped on the test vehicle, and the background vehicle is used to assist the test vehicle in testing the detection area. The first test equipment is also installed on the test vehicle. The first test equipment includes GPS module, dual-vehicle data master module, data acquisition equipment i-TESTER, and alarm signal acquisition equipment AVAD3. The background vehicle is equipped with the second test equipment. The second The test equipment includes GPS equipment, dual-vehicle data slave modules, and data acquisition equipment i-TESTER. The GPS equipment in the test vehicle and the background vehicle use Qia...

Abstract

The invention relates to the technical field of vehicle active lane changing performance test, and particularly relates to a vehicle active lane changing system test evaluation method. The method comprises a detection area test step and a lane changing test step. In the detection area test step, through the test, when a background vehicle and a test vehicle are located at different positions, detection distances D1, Dr and Dm of the background vehicle which can be detected by the test vehicle are obtained. In the lane changing test step, through the test, under different lane changing test speeds Vb and lane changing directions, lane changing start time, lane changing completion time, lane changing transverse acceleration and lane changing acceleration change rate can be obtained. By the adoption of the scheme, the active lane changing system is completely, scientifically and effectively tested, so that the active lane changing system is accurately evaluated, major traffic accidents caused when the system is used are avoided, or the situation that a driver does not trust the system, and therefore the system is abandoned is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle active lane change performance testing, in particular to a test and evaluation method for vehicle active lane change systems. Background technique [0002] With the development of automobile technology, people's functional requirements for automobiles are no longer limited to driving, but they hope to obtain more functions, so as to bring better driving experience to drivers. Therefore, intelligence and networking have gradually become one of the reference indicators for drivers to buy cars, and one of the manifestations of intelligence is the automatic lane change of the car, through the vehicle active lane change system to assist the driver or realize the vehicle lane change completely autonomously , thus giving the driver an intelligent driving experience. [0003] The existing vehicle active lane change system uses sensors such as radars and cameras to obtain the road environment around the v...
