The first embodiment is as follows:
referring to the attached drawings, the invention discloses an intelligent networking automobile sensor testing method based on a complex meteorological environment, which comprises the following steps:
and S100, connecting the intelligent networking automobile to be tested with a test platform.
Specifically, the intelligent networking automobile to be tested needs to be placed in an experimental field, and each signal connecting line of the testing platform is connected with the intelligent networking automobile to be tested.
And step S200, providing driving behavior input for the intelligent networked automobile through the driving scene library of the test platform.
Specifically, the test platform can be connected with the intelligent networked automobile controller, the test platform comprises a driving scene library, and signals such as an accelerator, a brake, a speed, a steering and the like can be provided for the intelligent networked automobile controller, so that the driving behavior of the intelligent networked automobile is simulated, and the intelligent networked automobile controller considers that the current automobile is in a driving state of an actual road. The invention has the advantages that the driving scene library provides the simulated driving behavior input for the intelligent networked automobile to be tested, the actual test road is not needed, a dynamometer is not needed to be arranged in a laboratory for driving simulation, the driving behavior input is only an analog signal, other test conditions such as a complex meteorological environment, a vehicle-mounted sensor, a movable target and the like are all actual conditions, and the test precision is higher.
And step S300, the test platform controls the meteorological environment simulation device to provide a meteorological environment to be tested for the intelligent networking automobile sensor to be tested.
Firstly, the vehicle-mounted sensor and the characteristics of the intelligent networked automobile are analyzed.
1. The laser radar acquires reflection information by emitting a laser beam to generate a target multi-dimensional image, however, the laser can be seriously attenuated in weather such as rain, snow, fog and haze, the transmission distance can be reduced, and the detection range and the detection precision of the laser radar can be influenced.
2. The millimeter wave radar generates a target image by emitting millimeter waves and receiving reflected signals, and the millimeter wave radar is similar to the laser radar, so that the detection range and the detection precision are reduced in weather such as rain, snow, fog, haze and the like.
3. The transmission speed and the transmission distance of the ultrasonic radar are reduced in rain, snow, fog and haze, particularly in a rain and snow environment.
4. The camera obtains information through catching object shape, but the meteorological environment that illumination, sleet and haze etc. caused the influence to visibility all can cause the influence to camera collection precision and detection range.
Of course, the sensors of the smart networked automobile also include an IMU inertial navigation sensor, a GPS positioning sensor, a communication module, etc., but these devices are less affected by the complex weather environment and are therefore outside the testing scope of the present invention.
In view of this, the meteorological environment to be tested in the invention preferably selects the factors which have great influence on the intelligent networked automobile sensor, and for the convenience of testing, the meteorological environment to be tested comprises three environments of rain, fog and illumination. Wherein, unify the environment that merges the rain with the environment of snow and test, merge the environment of haze to the environment of fog, can reduce the test procedure like this.
Specifically, the rain environment is achieved by a water droplet spray head. The size of the water drop spray head can be adjusted, and the water drop spray head is used for simulating different raindrops; and can adjust water pressure, flow for adjust rainfall.
The mist environment is achieved by a nebulizer. The pressure of the atomizer and the nozzle aperture are adjustable for adjusting the concentration and visibility of the mist.
The illumination environment is realized by the illuminating lamp and comprises strong light direct irradiation, dim light, light shadow and sudden change of illumination intensity. Highlight direct irradiation is used for judging the detection performance of camera under stronger light, and dim light is used for judging the detection performance of camera at the night condition, and the shadow is used for the detection performance in the illumination incomplete condition that has trees to lead to, and the illumination intensity sudden change is then the detection performance that is used for judging the light sudden change when passing in and out the tunnel.
Specifically, step S300 specifically includes the following steps:
step S310, providing an illumination environment for the intelligent networking automobile sensor to be tested, testing the test result of the camera in the complex illumination environment, and entering step S320 after the test is finished.
Step S320, providing a fog environment for the intelligent networking automobile sensor to be tested, testing the test results of the laser radar, the millimeter wave radar, the ultrasonic radar and the camera in the fog environment, and entering step S330 after the test is finished.
And S330, providing a rain environment for the intelligent networking automobile sensor to be tested, testing the test results of the laser radar, the millimeter wave radar, the ultrasonic radar and the camera in the rain environment, and stopping providing the meteorological environment to be tested after the test is finished.
Based on the testing steps S310-S330 of the invention, in the step S310, no influence exists on the intelligent networking automobile to be tested after the illumination test is finished, so the method is put in the first step; subsequently, in step S320, a fog environment test is performed, which may cause moisture influence on the sensor, and therefore, the process is performed in the second step; in step S330, a rain environment test is performed, and in this process, the influence of moisture caused by the fog environment test in step S320 is negligible. If the sequence of the steps is adjusted, the intelligent networked automobile to be tested needs to be dried and wiped, so that the testing progress is influenced, and the testing process is increased. The test method can realize rapid, convenient and low-cost measurement of the performance of the intelligent networking automobile sensor to be tested in the complex meteorological environment.
And S400, controlling the movable test target by the test platform according to the test requirement, and outputting a sensing signal by the intelligent networking automobile sensor to be tested according to the movable test target.
Specifically, the movable test target can comprise a dummy, an automobile simulation device and a road signboard and is limited by site size factors, and the intelligent internet vehicle to be tested is actually in a static state, so that the test is simulated through the movable test target. The test of the invention is the sensor test of the whole intelligent networking automobile, and the test target is also an actual target and is not a simulation signal, thus being capable of providing the accuracy of the performance test of the intelligent networking automobile sensor in a complex environment.
And S500, receiving the sensing signal by the intelligent networked automobile controller to be tested, and outputting an automobile control signal according to the sensing signal.
Specifically, the intelligent networked automobile controller to be tested receives input of sensor sensing signals in a complex environment scene, judges according to the sensing signals and outputs vehicle control signals.
And S600, the test platform receives the sensing signals and the vehicle control signals, compares the sensing signals and the vehicle control signals with the movable target information and the preset control action, and outputs a complex environment test result of the intelligent networking automobile sensor to be tested.
In one embodiment of the invention, the test platform is connected with the intelligent networking automobile sensor to be tested, and a sensing signal is directly obtained from the intelligent networking automobile sensor to be tested; or the test platform is not connected with the intelligent networking automobile sensor to be tested, only connected with the intelligent networking automobile controller to be tested, and receives the sensing signal from the intelligent networking automobile controller to be tested.
