Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a vehicle testing method according to an embodiment of the present invention, which is applicable to testing a working state of a controller in a vehicle, and is particularly applicable to testing a vehicle controller in different environments. The method can be executed by the vehicle testing device provided by the embodiment of the invention, and the device can be realized in a software and/or hardware mode. The apparatus can be configured in an electronic device, and the method specifically includes:
and S110, inputting actual environment data into a test bin of the vehicle so as to enable the vehicle to be in a simulated environment of an actual environment.
The test bin is used for testing vehicles, and vehicles needing to be tested can be parked in the test bin. An annular visual curtain and a stereo sound are arranged in the test chamber. The actual environment data refers to pre-collected audio data of different environments. The simulation environment refers to an environment scene which is constructed by adopting pre-collected actual environment data and simulates an actual environment.
Specifically, the camera device is adopted to collect actual environment data in different scenes in advance, and the collected scenes can include street scenes and mountain scenes. The camera equipment has a camera shooting function and a recording function, audio data in a street scene comprise audio data of a person and audio data of other vehicles, and the audio data comprise sound data and video data. The camera device stores the acquired actual environment data in a vehicle test system, which may be a simulation test system, such as a vaHil (vehicle hardware in loop) test system. The method comprises the steps of placing a vehicle in a test bin corresponding to a vehicle test system in advance, adjusting the temperature in the test bin to a test temperature meeting test requirements, after the temperature in the test bin is stably maintained at the test temperature, projecting actual environment videos in actual environment data to an annular visual curtain in the test bin by the vehicle test system, and playing the actual environment videos corresponding to the actual environment videos projected to the annular visual curtain in the actual environment data through a stereo system during use. Optionally, when the actual environment audio is played through the stereo, the playing volume of the stereo is adjusted to a decibel value consistent with the environment volume corresponding to the actual environment data. The vehicle testing system reproduces the simulated environment of the actual environment in the testing bin through the annular visual curtain and the stereo sound in the testing bin, so that the vehicle in the testing bin can be in the simulated environment of the actual environment.
Preferably, before the vehicle test is performed, it is required to determine whether the entire vehicle network is in a dormant state, that is, whether each controller in the vehicle is in a dormant state. If the whole vehicle network is in a dormant state, vehicle testing can be carried out; if the whole vehicle network is not in the dormant state, the controllers in the running state exist in the vehicle, at the moment, the vehicle testing system detects each controller in the vehicle, determines the controllers in the running state and the running reasons of the controllers, and sends the names of the controllers in the running state and the running reasons of the controllers to a user. Optionally, if the entire vehicle network is not in the dormant state, a controller operation report may be generated according to the name of the controller in the operation state and the operation reason of the controller, and the controller operation report is sent to the user, so that the user adjusts the controller in the operation state based on the controller operation report, and the entire vehicle network is in the dormant state, so as to further test the vehicle.
Illustratively, the actual environmental data includes at least one of diurnal transformation data, rainfall environmental data, thunderstorm environmental data, and high wind environmental data.
Specifically, when day and night transformation data are collected, light intensity data at different times need to be collected; the collected rainfall environment data needs to collect environment data under the condition of different rainfall, for example, the rainfall environment data can comprise light rain environment data, medium rain environment data and heavy rain environment data; when thunder environment data are collected, light intensity data and thunder sound data in a thunder environment need to be collected; when strong wind environment data are collected, environment data under the conditions of different wind directions and different wind power grades need to be collected.
And S120, collecting vehicle control information and vehicle current information.
The vehicle control information refers to operation-related data of a vehicle controller, and the vehicle controller is a core control device for controlling the starting, running, advancing and retreating, speed and stopping of a vehicle motor and other electronic devices of the vehicle. For example, the vehicle control information may include an operating state of a vehicle controller. The operating states of the vehicle controller include a sleep state and an operating state. And the current information of the whole vehicle is the quiescent current data of the whole vehicle.
Specifically, when the vehicle is in a simulation environment of an actual environment, the working conditions of each Controller in the vehicle are sent to a vehicle testing system through a Controller Area Network (CAN) bus, the vehicle testing system summarizes information transmitted by the CAN bus into vehicle control information, and the vehicle testing system CAN determine whether the Controller in a running state exists in the vehicle according to the vehicle control information. The static current collection equipment is connected in series to a whole vehicle current loop at the negative electrode of the vehicle storage battery, the whole vehicle static current data can be collected through the upper computer after the vehicle is dormant, and the whole vehicle static current data collected by the static current collection equipment is used as the whole vehicle current information. The static current collecting device may be a precision ammeter.
For example, the diurnal conversion data and rainfall environment data may be input into a ring vision curtain and stereo sound in the test chamber, leaving the vehicle in the test chamber in the diurnal conversion environment and the rainfall environment. Under the condition that the vehicle is in a simulated environment of an actual environment, the quiescent current of the whole vehicle is measured through a precise ammeter, and vehicle control information is acquired through a CAN bus.
And S130, determining whether each controller in the vehicle is normal or not and whether the vehicle has the abnormal static current phenomenon or not according to the vehicle control information, the actual environment data and the whole vehicle current information.
It should be noted that the operating state of each controller in the vehicle may be an operating state or a sleep state. When the vehicle is powered off, each controller in the vehicle is in a dormant state when not receiving a wake-up signal, the wake-up signal is a signal capable of enabling the working state of each controller in the vehicle to be changed from the dormant state to the running state, for example, when the environment is changed from a sunny environment to a rainfall environment, the rainfall environment can be used as a wake-up signal of a rainfall sensor, the rainfall sensor is changed from the dormant state to the running state after receiving the wake-up signal, when rainwater is detected to exist on a windshield of the vehicle, an instruction is sent to a windshield wiper to enable the windshield wiper to start working so as to remove the rainwater on the windshield, and when the rainfall sensor detects that the rainwater is removed or the working time of the windshield wiper meets the preset time, the rainfall sensor automatically enters the dormant state. When each controller in the vehicle is in a dormant state, the quiescent current of the whole vehicle is maintained at a lower quiescent current value, about dozens of milliamperes to dozens of milliamperes, for example, when each controller in the vehicle is in a dormant state, the quiescent current of the whole vehicle can be maintained at 10 mA-80 mA; when the controller in the non-sleep mode exists in the vehicle, the static current value of the whole vehicle is high, about hundreds of milliamperes to several amperes, for example, when the controller in the non-sleep mode exists in the vehicle of part of vehicles, the static current of the whole vehicle can be 700 mA-1A. If the controller in the vehicle does not receive the correct wake-up signal, the controller is converted from the dormant state into the running state, and the abnormal phenomenon of static current of the vehicle can be caused; or after the controller in the vehicle finishes working in the running state, the controller cannot automatically enter the dormant state in time, so that the abnormal phenomenon of static current can also occur to the vehicle, and the abnormal phenomenon of the static current can cause the power shortage of a vehicle storage battery, so that the vehicle cannot be started normally.
Specifically, after a vehicle test system acquires vehicle control information and whole vehicle current information, the working state of each controller in a vehicle is determined according to the vehicle control information; determining whether the measured static current value of the whole vehicle accords with the working state of each controller in the current vehicle according to the current information of the whole vehicle; and finally, determining whether the working state of each controller in the current vehicle accords with the simulated environment constructed by the actual environment data according to the actual environment data input into the test bin. For example, if the actual environment data input into the test bin is rainfall environment data, it is determined whether a rainfall sensor in the current vehicle is in an operating state, and if the rainfall sensor is in the operating state, the operating state of the rainfall sensor in the vehicle conforms to a simulated environment constructed by the actual environment data. If the static current value of the whole vehicle accords with the working state of each controller in the current vehicle and the working state of each controller in the current vehicle accords with the simulation environment, determining that each controller in the vehicle is normal and the vehicle does not have the abnormal phenomenon of static current; if the static current value of the whole vehicle does not accord with the working state of each controller in the current vehicle, determining that the static current abnormal phenomenon exists in the vehicle; if the working state of each controller in the current vehicle does not accord with the simulated environment, the abnormal controller is determined to exist in the vehicle, and the abnormal controller can cause the abnormal phenomenon of the static current in the vehicle.
For example, if all controllers in the vehicle are in a dormant state and the measured static current value of the whole vehicle conforms to the corresponding static current value range when the vehicle is in the dormant state, determining that the static current abnormal phenomenon does not exist in the vehicle; if all controllers in the vehicle are in a dormant state, but the measured static current value of the whole vehicle is larger than the design index of the static current value of the whole vehicle, the fact that the static current abnormal phenomenon exists in the vehicle is determined, and the static current abnormal phenomenon is irrelevant to the working state of the controllers at the moment, possibly because the static current abnormal phenomenon exists in the vehicle in the dormant state. The design index of the whole vehicle static current value is the corresponding static current value set according to the actual condition of the vehicle when the vehicle is in a dormant state. Determining whether the vehicle should be in a dormant state under a simulated environment constructed by the actual environment data according to the actual environment data, wherein if each controller in the vehicle should be in the dormant state under the simulated environment, the working state of each controller in the vehicle is normal; if a controller in an operating state should exist in the vehicle in the simulated environment, the controller that determines that an abnormality exists in the vehicle is determined. Further, if a controller in a running state exists in the vehicle, determining whether the vehicle should be in the running state under a simulation environment constructed by actual environment data according to the actual environment data, and if the controller in the running state should exist in the vehicle under the simulation environment, determining that the states of all controllers in the vehicle are normal, wherein the static current abnormal phenomenon caused by the abnormal controller does not exist in the vehicle; if the controller in the running state should not exist in the vehicle under the simulation environment, the controller with the abnormality in the vehicle is determined, and the electrostatic current abnormality phenomenon caused by the abnormality of the controller exists in the vehicle.
The technical scheme provided by the embodiment solves the problem that when a vehicle is tested and whether the static current abnormal problem exists in the vehicle is judged only through the working state of the vehicle controller, the static current abnormal problem exists in the vehicle is judged only when the vehicle controller is in a dormant state but the static current value of the whole vehicle is too high, the influence of the surrounding environment factors of the vehicle on the vehicle controller is not considered, the problem of the vehicle static current abnormal caused by the abnormal operation phenomenon of the vehicle controller is not considered, and the obtained vehicle test result is inaccurate.
According to the technical scheme provided by the embodiment, the vehicle is in a simulation environment of an actual environment by inputting actual environment data into the test bin of the vehicle; collecting vehicle control information and vehicle current information; and determining whether each controller in the vehicle is normal or not according to the vehicle control information, the actual environment data and the whole vehicle current information. Through the vehicle test system in the scheme, the vehicle is placed in the test bin, the vehicle in the test bin can be in the simulation environment of the actual environment through the actual environment data collected in advance, when the vehicle is tested, the influence of the ambient environment factors of the vehicle on the working state of the vehicle controller is fully considered, the abnormal problem of the vehicle static current caused by the abnormal operation of the controller is fully considered when whether the abnormal phenomenon of the vehicle exists or not is determined, the vehicle test is more comprehensive, and the vehicle test precision is improved.
Example two
Fig. 2 is a flowchart of a vehicle testing method according to a second embodiment of the present invention, which is optimized based on the above embodiments, and provides a preferred embodiment of determining the operating states of the controllers in the vehicle according to the vehicle control information, and determining whether the controllers in the vehicle are normal according to the operating states and the vehicle current information. Specifically, as shown in fig. 2, the vehicle testing method provided in this embodiment may include:
s210, inputting actual environment data into a test bin of the vehicle so as to enable the vehicle to be in a simulated environment of an actual environment.
And S220, collecting vehicle control information and vehicle current information.
And S230, determining the working state of each controller in the vehicle according to the vehicle control information.
Specifically, after the vehicle test system obtains the vehicle control information, the name of the controller in the vehicle in the sleep state and the name of the controller in the vehicle in the running state may be determined according to the vehicle control information.
For example, the operating state of each controller in the vehicle is determined according to the corresponding state bit of each controller in the vehicle control information.
Specifically, when the vehicle is in a simulation environment of an actual environment, the vehicle control information is sent to the vehicle testing system in the form of a network management message through the CAN bus, and the name of each controller in the vehicle and the status bit of each controller are recorded in the network management message. For example, the status bit of the controller recorded in the network management message may be represented by 0 or 1, where a 0 status bit indicates that the controller is in a sleep state, and a 1 status bit indicates that the controller is in a run state. Further, the names of the controllers in the vehicle and the corresponding working states of the controllers can be determined through the network management message.
The name of the controller in the running state in the vehicle is determined according to the state bit corresponding to each controller, and the efficiency of determining the working state of the controller can be improved.
S240, determining whether each controller in the vehicle is normal or not and whether the vehicle has the abnormal static current phenomenon or not according to the working state, the actual environment data and the current information of the whole vehicle.
Specifically, the names of the controllers in the vehicle and the vehicle static current value conditions when the controllers are in the running state may be stored in the vehicle test system in advance. If the controller in the running state exists in the vehicle, the name of the controller in the running state can be judged according to vehicle control information, whether the static current value of the whole vehicle meets the static current value condition corresponding to the controller in the running state or not is determined, and if the static current value meets the static current value condition, the static current abnormal phenomenon does not exist in the vehicle; if not, determining that the static current abnormal phenomenon exists in the vehicle. Further, a controller in an operating state exists in the vehicle, the name of the controller in the operating state is judged according to the vehicle control information, whether the controller is in the operating state under the simulation environment constructed by the actual environment data is further determined according to the actual environment data, and if yes, the controller is determined to be normal; if not, determining that the controller is abnormal.
Preferably, different controller running time conditions can be stipulated for simulation environments constructed by different actual environment data in advance, and if the working state of each controller in the current vehicle meets the simulation environment and the running time of the controller meets the controller running time conditions in the simulation environment, the working state of the controller is determined to be normal; and if the running time of the controller does not meet the running time condition of the controller, determining that the working state of the controller is abnormal.
Optionally, in this embodiment, whether the controller is normal or not and whether the vehicle has an abnormal static current phenomenon may also be determined according to the operating state and the actual state of the controller and the current information of the entire vehicle, which may specifically be implemented by the following sub-steps:
s2401, for any controller in the vehicle, if the working state of the controller is the running state, determining the actual state of the controller according to the actual environment data.
The actual state refers to a working state of the vehicle controller under a normal condition when the vehicle is in a simulated environment constructed by actual environment data. For example, when the actual environment data is rainfall environment data, the actual state of the rainfall sensor should be an operating state; when the actual environment data is the non-rainfall environment data, the actual state of the rainfall sensor should be the dormant state.
Specifically, after the vehicle test system acquires the vehicle control information and the entire vehicle current information, if the controller in the running state is determined to exist in the vehicle according to the vehicle control information, the name of the controller in the running state is further determined according to the vehicle control information. And determining the actual state of the controller in the running state under the simulation environment according to the actual environment data.
S2402, determining whether the controller is normal or not and whether the vehicle has an abnormal static current phenomenon or not according to the running state, the actual state and the current information of the whole vehicle.
Specifically, if the running state is inconsistent with the actual state, the controller has an abnormal running phenomenon, namely the controller is abnormal, the vehicle has an electrostatic current abnormal phenomenon caused by the abnormal running of the controller, and the name of the controller in the abnormal running state is determined according to the working state of each controller in the vehicle, so that the abnormal controller is positioned, and the controller which is abnormal causes the electrostatic current abnormal phenomenon of the vehicle is determined; if the running state is consistent with the actual state, the controller is normal, whether the finished automobile static current value of the automobile accords with the static current value condition corresponding to the controller in the running state can be further determined according to the finished automobile current information, and if the finished automobile static current value accords with the static current value condition, the abnormal static current phenomenon does not exist in the automobile; if not, determining that the static current abnormal phenomenon exists in the vehicle. For example, a solar-rain sensor may control the closing of a vehicle sunroof based on the environmental conditions in the area of the vehicle. When the vehicle is in a rainfall environment, if the vehicle skylight is in an opening state, the sunlight and rain sensor can be changed from a dormant state to a running state and close the vehicle skylight. Specifically, if the sunlight and rainfall sensor in the vehicle is determined to be in the running state and the skylight is closed according to the vehicle control information, whether the simulated environment is a rainfall environment or not is determined according to the actual environment data, if the simulated environment is not in the rainfall environment, the sunlight and rainfall sensor is determined to have the abnormal running phenomenon, and the vehicle has the electrostatic current abnormal phenomenon caused by the abnormal running of the sunlight and rainfall sensor. Further, when the vehicle is in a rainfall environment, the sunlight and rain sensor changes from a dormant state to an operating state and closes a vehicle skylight, and then can enter the dormant state again within a preset time, so that the sunlight and rain sensor is normal; if the vehicle does not enter the dormant state again within the preset time, the sunlight and rain sensor is abnormal.
For example, if it is determined that a rainfall sensor in the vehicle is in an operating state according to the vehicle control information, it is determined whether the simulated environment is a rainfall environment according to the actual environment data, and if the simulated environment is not a rainfall environment, it is determined that the rainfall sensor is abnormal; and if the simulated environment is a rainfall environment, judging the rainfall condition in the rainfall environment according to the actual environment data, and determining whether the running time of the rainfall sensor meets the running time condition of the controller or not according to the rainfall condition. The running time conditions of different controllers can be preset according to actual requirements, for example, in a light rain environment, the running time conditions are that the rainfall sensor needs to automatically enter a dormant state when the running time is less than 2 minutes; in a medium rain environment, the running time condition is that the rainfall sensor needs to automatically enter a dormant state when the running time is less than 4 minutes; in heavy rain conditions, the runtime condition is that the rain sensor needs to automatically go to sleep when the runtime is less than 6 minutes. If the running time of the rainfall sensor meets the running time condition of the controller, the rainfall sensor is normal; and if the running time of the rainfall sensor does not meet the running time condition of the controller, the rainfall sensor is abnormal.
And determining whether the controller is normal or not and whether the vehicle has the abnormal phenomenon of static current or not according to the running state and the actual state of the vehicle controller and the current information of the whole vehicle. Whether the controller is normal can be determined by comparing whether the running state and the actual state of the controller are consistent, a flexible judgment mode is provided for judging whether the controller is normal, and the vehicle testing efficiency is improved.
According to the technical scheme of the embodiment, the working state of each controller in the vehicle is determined according to the vehicle control information; and determining whether each controller in the vehicle is normal or not and whether the vehicle has the abnormal phenomenon of static current or not according to the working state, the actual environment data and the current information of the whole vehicle. According to the scheme, when the vehicle is tested, the name of the controller with the abnormal operation state can be further determined when the operation state of the controller is abnormal, so that the controller with the abnormal operation state is preliminarily positioned, and later-stage maintenance personnel can maintain the abnormal controller conveniently. Meanwhile, the difference of the current information of the whole vehicle when different controllers are in the running state is considered, and by means of the scheme, a more accurate test result of the abnormal phenomenon of the static current of the vehicle can be obtained.

Specifically, as shown in fig. 3, the vehicle testing method provided in this embodiment may include:
and S310, inputting actual environment data into a test bin of the vehicle so as to enable the vehicle to be in a simulated environment of an actual environment.
And S320, collecting vehicle control information and vehicle current information.
