[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] In order to solve the problem of low efficiency of unmanned vehicle maintenance methods in the prior art, the present invention provides a vehicle maintenance detection method based on status lights to collect vehicle information, driving mode information and status information of each functional module of a vehicle to be tested, and jointly display the detection result information through a human-machine interface and a status light and a voice announcer of an interactive module. The vehicle number of the vehicle to be tested, the current driving mode, and the status of the functional modules currently being maintained can be displayed on the human-machine interface. When a functional module failure occurs, the status light and the voice announcer jointly indicate that the overall method can automatically detect whether each functional module is normal. The operation is convenient, and the status information of each functional module is displayed from multiple aspects through the status light, the voice announcer and the human-machine interface. The detection result display is intuitive and effective, which can effectively improve maintenance efficiency, reduce the risk of missed detection, and improve the safety of unmanned vehicles.

[0027] See also Figure 1 and Figure 2 In this embodiment, the vehicle to be tested 10 is a vehicle with an unmanned driving mode, which is configured with a functional module 11 that can be used to realize unmanned driving. The interactive module 21 is placed on the vehicle to be tested 10 and is communicated with the functional module 11 through the tester 20. The tester 20 can receive the fault code issued by the functional module 11 to determine whether the corresponding functional module is normal based on whether the fault code is received, and control the interactive module 21 to display the corresponding result information. The tester also includes a human-machine interface for realizing test operations and displaying test result information based on a graphical user interface.

[0028] Specifically, the vehicle maintenance detection method of this embodiment is mainly applied in the tester 20, and includes:

[0029] Step S01: collecting vehicle information and driving mode information of the vehicle to be tested, and outputting the vehicle information and the driving mode information to a human-machine interface for display.

[0030] Step S02: collecting status information of each functional module of the vehicle to be tested, obtaining test result information of each functional module according to the status information, and outputting the test result information to the human-machine interface for display, wherein the status information includes a fault code.

[0031] Step S03: driving the interaction module according to the test result information, the driving mode information and a preset interaction mapping relationship, so that the output state of the interaction module matches the test result information of each functional module.

[0032] Among them, the interactive module includes a status light and a voice announcer, and the human-machine interface is used to display the vehicle number of the vehicle to be tested, the current driving mode, and the fault status of the functional module of the current maintenance test. The interactive mapping relationship is mainly the working state configuration of the status light and the voice announcer when the corresponding functional module test results are normal and faulty respectively.

[0033] Among them, the interactive module 21 can be specifically placed on the top of the front of the vehicle, so that the lighting status of the status light can be observed from both inside and outside the vehicle. The tester 20 is used to output maintenance test instructions to the vehicle to be tested 10 and control the operation of the functional module 11 of the vehicle to be tested 10. The human-machine interface configured by the tester 20 can display test result information such as the vehicle number of the vehicle to be tested, the current driving mode, the status of the currently maintained functional module, etc. The obtained test result information can also be stored through the tester 20 or uploaded to the background server.

[0034] Based on the current safety technical requirements for driverless vehicles, the driving modes of the vehicle to be tested include automatic driving mode, manual driving mode and manual takeover mode. Correspondingly, the step of matching the output state of the interactive module with the test result information of each functional module also includes: in the manual driving mode or the manual takeover mode, the status lights are all off and the voice announcer is in a non-announcement state. That is, when manual intervention in driving occurs, it is up to the manual operator to determine whether each function is normal.

[0035] The step of matching the output state of the interactive module with the test result information of each functional module also includes: when the state information of the functional module currently being tested is normal, controlling the corresponding state light to be in a permanent green state. When the tester 20 controls the functional module 11 to perform maintenance testing, the functional module 11 provides information feedback according to its own operating state. When it cannot operate normally, it will feedback a fault code and send it to the communication bus. The tester 20 is connected to the communication bus and can determine whether the functional module currently being tested is normal according to whether a fault code is received during the maintenance test.

[0036] In order to realize the intuitiveness of the test result display, in this embodiment, the step of matching the output state of the interactive module with the test result information of each functional module also includes: when the status information of the functional module currently being tested is a fault, controlling the corresponding status light to be in a flashing state, and the flashing colors corresponding to different functional module faults are different from each other. Different flashing colors are used to indicate different functional module faults, so as to intuitively distinguish the faulty functional modules.

[0037] To further enhance the intuitiveness of the test result display, the step of matching the output state of the interactive module with the test result information of each functional module also includes: when the status information of the functional module currently being tested is a fault, controlling the corresponding voice announcer to broadcast the preset voice information corresponding to the fault of the functional module currently being tested. Using voice broadcast to broadcast the name of the faulty functional module and the fault status information can reduce the strong recognition of the flashing color displayed by the status light and reduce the dependence on color recognition.

[0038] The preset voice information also includes preset reminder voice information to alert surrounding vehicles and personnel, so as to increase the attention of surrounding vehicles and personnel to the faulty vehicle to be tested and avoid safety problems caused by operation. For example, in batch maintenance tests of the same model, the same model is prone to the same fault. When any functional module in any of the vehicles to be tested fails, the preset reminder voice information is played to remind surrounding vehicles and personnel to pay attention, so as to focus on the same functional module in the maintenance of other vehicles and reduce the risk of missed detection.

[0039] In a specific example, the functional modules include a CAN communication module, a system module, a perception module, a network module, a planning module, a control module, a prediction module, a positioning module, a fusion module, a chassis module, and a sensor hardware module. The flashing colors of the status lights include yellow, red, orange, purple, pink, blue, white, and dark red. Since the number of available colors is less than the number of functional modules, when some modules in the functional modules fail, the corresponding flashing colors of the status lights are the same. Combined with the detection result information displayed by the voice announcer and the human-computer interface, the specific functional module where the failure occurs can also be accurately determined.

[0040] Among them, the specific color configuration can be flexibly set, and this application does not make any special limitations on this. That is, the specific configuration of the interactive mapping relationship can be flexibly set according to user preferences. The specific setting will not affect the implementation of the technical solution of this application. Various specific configurations can achieve the expected interactive effect and improve maintenance efficiency.

[0041] In order to reduce the time consumption of maintenance and detection, in a specific example, the interactive module 21 is provided with multiple status lights, which are set one by one corresponding to each functional module, and the detection results of all functional modules can be displayed at the same time. And each status light includes a green constant light state, which can be switched between color flashing, green constant light and constant off, corresponding to fault, normal and non-automatic driving mode respectively.

[0042] In order to reduce the cost of the two-color status light, in an optional embodiment, the status light includes multiple status lights, and one functional module corresponds to two status lights, one of the two status lights is used for green constant light indication, and the other is used for color flashing indication, which can reduce the hardware cost of the multi-color status light. Among them, the status light can be selected from light-emitting diodes, which have high energy efficiency and low requirements for driving power supply, which can reduce the implementation cost of the status light.

[0043] The vehicle maintenance detection method based on status lights provided by the present invention collects vehicle information, driving mode information and status information of each functional module of the vehicle to be tested, and jointly displays the detection result information through the human-machine interface and the status lights and voice announcer of the interactive module, wherein the vehicle number of the vehicle to be tested, the current driving mode, the status of the currently maintained functional module and other maintenance information can be displayed on the human-machine interface, and when a functional module failure occurs, the status lights and voice announcer jointly highlight the indication. The vehicle maintenance detection method based on status lights provided by the present invention can automatically detect whether each functional module is normal, and the operation is convenient. The status information of each functional module is displayed from multiple aspects through the status lights, voice announcer and human-machine interface. The display of the detection results is intuitive and effective, which can effectively improve the maintenance efficiency, reduce the risk of missed detection, and improve the safety of unmanned vehicles.
