[0042] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, in which the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0043] The driving scene reconstruction test method, device, vehicle and storage medium of the embodiments of the present application are described below with reference to the accompanying drawings. In view of the problem of slow real vehicle test adjustment and thus reduced test efficiency due to the fixed service signal relationship of the communication mode based on CAN signals mentioned in the background art, the present application provides a driving scene reconstruction test method. In the method, when a user's driving scene reconstruction test instruction is received, a pre-set SOA service test tool is used to send a DDS service signal and an Ntf service signal to a vehicle machine to be tested, and an actual driving scene reconstruction result constructed based on the DDS service signal and the Ntf service signal is obtained. A driving scene reconstruction test result is generated according to the actual driving scene reconstruction result and a target driving scene reconstruction result corresponding to the DDS service signal. Thus, the problem of slow real vehicle test adjustment and thus reduced test efficiency due to the fixed service signal relationship of the communication mode based on CAN signals is solved. The service signal is sent through the SOA service architecture to simulate the real vehicle test environment and complex road condition information, thereby reducing the test cost and improving the flexibility in the software test and update process.

[0044] Specifically, Figure 1 A flowchart of a driving scene reconstruction test method provided by an embodiment of the present application is shown.

[0045] As Figure 1 shown, the driving scene reconstruction test method includes the following steps:

[0046] In step S101, it is determined whether a user's driving scene reconstruction test instruction is received.

[0047] Specifically, in the embodiments of the present application, in order to improve the driving safety of users and avoid traffic accidents during driving, the sensors of the vehicle are used to continuously collect dangerous targets around the vehicle during vehicle driving. When it is detected that there are dangerous targets around the vehicle, such as vehicles, pedestrians and animals around the vehicle, the user is reminded in time to help the user take appropriate measures to avoid possible dangers. Therefore, driving scene reconstruction test of the vehicle is an important link for driving safety.

[0048] Further, in the test process of the vehicle of the embodiments of the present application, it is first determined whether a user's driving scene reconstruction test instruction is received, and then when the user's driving scene reconstruction test instruction is received, a vehicle test environment is built. In the test environment building, as Figure 2As shown, test components including a direct current stabilized power supply, a to-be-tested car machine, a display screen and a vehicle-mounted Ethernet converter are required. The direct current stabilized power supply respectively supplies power to the to-be-tested car machine, the display screen and the vehicle-mounted Ethernet converter. The vehicle-mounted Ethernet converter is respectively connected with the to-be-tested car machine and a computer terminal, and is used to send an emulated Ethernet ADAS (Advanced Driving Assistance System) signal to the to-be-tested car machine.

[0049] In step S102, if a driving scene reconstruction test instruction is received, the DDS service signal and the Ntf service signal are sent to the to-be-tested car machine by using a preset SOA service test tool, and an actual driving scene reconstruction result constructed by the to-be-tested car machine based on the DDS service signal and the Ntf service signal is obtained.

[0050] Further, in an embodiment of the present application, before the DDS service signal and the Ntf service signal are sent to the to-be-tested car machine by using the preset SOA service test tool, the following steps are further included: a scene reconstruction Ethernet signal of intelligent driving is sent to the to-be-tested car machine, and a power ON gear signal, a current gear signal and a current vehicle speed signal are continuously sent to the to-be-tested car machine by using a preset service simulation tool; it is judged whether the to-be-tested car machine simulates a real vehicle power-on state based on the power ON gear signal, and whether the to-be-tested car machine simulates a driving process based on the current gear signal and the current vehicle speed signal; if the to-be-tested car machine simulates the real vehicle power-on state based on the power ON gear signal, and simulates the driving process based on the current gear signal and the current vehicle speed signal, the DDS service signal and the Ntf service signal are sent to the to-be-tested car machine by using the preset SOA service test tool.

[0051] The preset service simulation tool can be a simulation tool used by a person skilled in the art according to actual test requirements, which is not specifically limited here.

[0052] Specifically, as shown in FIG. 1, the test system includes a direct current stabilized power supply 1, a to-be-tested car machine 2, a display screen 3 and a vehicle-mounted Ethernet converter 4. Figure 3As shown in the embodiment of this application, when receiving a driving scenario reconstruction test command issued by a user, the system sends a scene reconstruction Ethernet signal for intelligent driving to the vehicle under test through an onboard Ethernet converter. It also continuously sends a power ON signal, a current gear signal (e.g., D or R), and a current vehicle speed signal to the vehicle under test using a preset service simulation tool. The system determines whether the vehicle under test is simulating a real vehicle power-on state based on the power ON signal and whether it is simulating a driving process based on the current gear and current speed signals. If it detects that the vehicle under test is simulating a real vehicle power-on state based on the power ON signal and simulating a driving process based on the current gear and current speed signals, then it uses a preset SOA service test tool to simulate sending DDS service signals and NTF service signals to the vehicle under test. The system then obtains the actual driving scenario reconstruction result constructed by the vehicle under test based on the DDS service signals and NTF service signals, as well as the target driving scenario reconstruction result corresponding to the DDS service signals.

[0053] In this application embodiment, the actual driving scenario reconstruction result and the target driving scenario reconstruction result include at least one of simulated target scenario reconstruction, simulated road scenario reconstruction, simulated traffic light scenario reconstruction, and simulated traffic sign scenario reconstruction. In the actual driving scenario reconstruction result, if the target scenario is simulated, targets such as pedestrians, vehicles, animals, and props are sent to the vehicle-to-vehicle system under test; if the road scenario is simulated, targets such as lane correction alarm lines, centering lane lines, lane changing lane lines, ACC (Adaptive Cruise Control) lane lines, and cruise lane lines are sent to the vehicle-to-vehicle system under test; if the traffic light scenario is simulated, targets such as traffic lights for the left lane, the current lane, and the right lane, as well as pedestrian crossings, are sent to the vehicle-to-vehicle system under test; if the traffic sign scenario is simulated, prohibitory signs, warning signs, and instruction signs are sent to the vehicle-to-vehicle system under test.

[0054] Furthermore, in one embodiment of this application, after sending the DDS service signal and NTF service signal to the vehicle unit under test using a preset SOA service testing tool, the method further includes: determining whether the DDS service signal has changed; when the DDS service signal changes, broadcasting the signal change information based on a preset NTF method, and after the vehicle unit under test detects the signal change information, switching the parameter value of the DDS service signal according to the preset NTF method.

[0055] Specifically, in the embodiment of the present application, after the actual driving scene reconstruction result constructed by the DDS service signal and the Ntf service signal is received by the to-be-tested car machine, it is necessary to judge whether the DDS service signal changes, and when the DDS service signal changes, the server broadcasts the changed signal based on the preset Ntf method, and after the to-be-tested car machine monitors the signal change information, the to-be-tested car machine switches the corresponding display according to the parameter value in the Ntf method.

[0056] In step S103, a driving scene reconstruction test result is generated according to the actual driving scene reconstruction result and the target driving scene reconstruction result corresponding to the DDS service signal.

[0057] Further, in an embodiment of the present application, generating the driving scene reconstruction test result according to the actual driving scene reconstruction result and the target driving scene reconstruction result corresponding to the DDS service signal includes: judging whether the actual driving scene reconstruction result is same as the target driving scene reconstruction result; if the actual driving scene reconstruction result is same as the target driving scene reconstruction result, the driving scene reconstruction test result is success, otherwise, the driving scene reconstruction test result is failure.

[0058] Specifically, in the embodiment of the present application, after the actual driving scene reconstruction result constructed by the DDS service signal and the Ntf service signal is received by the to-be-tested car machine, it is necessary to judge whether the DDS service signal changes, and when the DDS service signal changes, the server broadcasts the changed signal based on the preset Ntf method, and after the to-be-tested car machine monitors the signal change information, the to-be-tested car machine switches the corresponding display according to the parameter value in the Ntf method.

[0059] According to the driving scene reconstruction test method in the embodiment of the present application, when the driving scene reconstruction test instruction of the user is received, the DDS service signal and the Ntf service signal are sent to the to-be-tested car machine by using the preset SOA service test tool, and the actual driving scene reconstruction result constructed based on the DDS service signal and the Ntf service signal is obtained, and the driving scene reconstruction test result is generated according to the actual driving scene reconstruction result and the target driving scene reconstruction result corresponding to the DDS service signal. Therefore, the problem that the communication mode based on the CAN signal is fixed, the service signal relationship is fixed, the real car test is slow, and the test efficiency is reduced is solved, the service signal is sent by the SOA service architecture to simulate the real car test environment and the complex road condition information, so as to reduce the test cost and improve the flexibility in the software test and update process.

[0060] Secondly, the driving scene reconstruction test device according to the embodiment of the application is described with reference to the drawings.

[0065] The generating module 300 is configured to generate a driving scene reconstruction test result according to the actual driving scene reconstruction result and a target driving scene reconstruction result corresponding to the DDS service signal.

[0066] Further, in an embodiment of the application, the generating module 300 comprises:

[0067] A first judging unit is configured to judge whether the actual driving scene reconstruction result is same as the target driving scene reconstruction result.

[0068] If the actual driving scene reconstruction result is same as the target driving scene reconstruction result, the driving scene reconstruction test result is success, otherwise, the driving scene reconstruction test result is failure.

[0069] Further, in an embodiment of the application, before the DDS service signal and the Ntf service signal are sent to the to-be-tested car machine by using the preset SOA service test tool, the obtaining module 200 further comprises a sending unit, a second judging unit and a simulating unit.

[0070] The sending unit is configured to send a scene reconstruction Ethernet signal of intelligent driving to the to-be-tested car machine, and continuously send a power ON gear signal, a current gear signal and a current vehicle speed signal to the to-be-tested car machine by using a preset service simulation tool.

[0071] The second judging unit is configured to judge whether the to-be-tested car machine simulates a real vehicle power-on state based on the power ON gear signal, and whether the to-be-tested car machine simulates a driving process based on the current gear signal and the current vehicle speed signal.

[0073] Further, in an embodiment of the present application, the actual driving scene reconstruction result includes at least one of a simulated target scene reconstruction, a simulated road scene reconstruction, a simulated traffic light scene reconstruction, and a simulated traffic sign scene reconstruction.

[0074] Further, in an embodiment of the present application, after the DDS service signal and the Ntf service signal are sent to the vehicle to be tested by using the preset SOA service test tool, the acquisition module 200 further includes a third judgment unit and a switching unit.

[0075] The third judgment unit is configured to judge whether the DDS service signal changes.

[0076] The switching unit is configured to broadcast signal change information based on a preset Ntf method when the DDS service signal changes, and switch the parameter value of the DDS service signal according to the Ntf method after the vehicle to be tested monitors the signal change information.

Thus, the problem of slow real vehicle test adjustment and low test efficiency caused by the fixed relationship between service signals based on the CAN signal communication mode is solved. The SOA service architecture is used to send service signals to simulate a real vehicle test environment and complex road condition information, thereby reducing the test cost and improving the flexibility in the software test and update process.
