[0037] To more clearly illustrate the technical solutions in the embodiments or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0040] Figure 3 It is a method flow chart of a control method for an in-vehicle front view camera module provided by an embodiment of the present application;

[0041] Figure 4A schematic flowchart of a control device for an in-vehicle front-view camera module provided by an embodiment of the present application. Detailed implementation manners

[0042] The in-vehicle front-view camera module can be used to collect images in the vehicle's forward direction and has been widely applied in fields such as autonomous driving. For example, during vehicle driving, the in-vehicle front-view camera module can collect images of the vehicle's traveling direction to provide a reference for autonomous driving.

[0043] Generally, the in-vehicle front-view camera module can include a power module, a control module, a sensing input module, and a sensing processing module. The power module can supply power to each module in the in-vehicle front-view camera module. The control module can control each module in the in-vehicle front-view camera module. The sensing input module includes components related to image acquisition such as a camera and can be used to obtain images. The sensing processing module is connected to the sensing input module, can obtain the images collected by the sensing input module, and process the images.

[0044] In addition, the in-vehicle front-view camera module can also be connected to the vehicle bus to achieve communication between the in-vehicle front-view camera module and other devices on the vehicle. For example, the in-vehicle front-view camera module can communicate with the vehicle head unit through the vehicle bus to send the images collected by the camera to the vehicle head unit and display them to the user through a display screen.

[0045] The power consumption of the in-vehicle front-view camera module may be relatively high. In particular, if the vehicle is in an energy-saving state, the proportion of the power consumption of the in-vehicle front-view camera module in the total vehicle power consumption will increase significantly. To save energy, the in-vehicle front-view camera module can be turned off when it is not needed.

[0046] Currently, the in-vehicle front-view camera module can be controlled by an existing control module on the vehicle. For example, it can be controlled by the main control module of the vehicle. For example, after the vehicle enters the energy-saving state, the main control module can turn off the in-vehicle front-view camera module to avoid power consumption of the in-vehicle front-view camera module.

[0047] However, for reliability considerations, each control module in the vehicle often monitors each other. That is to say, control module A in the vehicle can obtain the working status of other control modules. If control module B goes offline, control module A can detect that control module B is offline and thus report a fault. That is to say, if a certain control module in the vehicle goes offline, other control modules may report an error due to the offline of this control module.

[0048] Therefore, if the in-vehicle front view camera module is controlled by an existing control module on the vehicle, after the control module in the in-vehicle front view camera module is turned off, other control modules on the vehicle may report errors, affecting the normal operation of the vehicle. Thus, in order to reduce the power consumption of the in-vehicle front view camera module, it is necessary to adjust the control module of the vehicle. However, the number of control modules on the vehicle is often large, and the workload of adjusting the vehicle control module is large. Moreover, it may also affect the diagnostic interaction strategy between multiple control modules, making the adjustment difficult.

[0049] Therefore, due to the large difficulty and workload of adjusting the control module, the current in-vehicle front view camera module often does not have the function of entering the energy-saving state.

[0050] To solve the above problems, an embodiment of the present application provides an in-vehicle front view camera module. The in-vehicle front view camera module can be installed on a vehicle, used to collect images in the driving direction of the vehicle, and can also be used to collect other images or implement other functions. Moreover, the in-vehicle front view camera module provided by the embodiment of the present application can also enter the energy-saving state to reduce power consumption.

[0051] Specifically, as Figure 1 shown, the in-vehicle front view camera module 100 may include a power management module 110, a sensing input module 120, a sensing processing module 130, and a control module 140.

[0052] Among them, the power management module 110 can be used to supply power to the modules in the in-vehicle front view camera module 100. Specifically, the power management module 110 can be connected to the vehicle power supply, so as to use the electric energy provided by the vehicle power supply to supply power to the modules in the in-vehicle front view camera module 100. Optionally, the power management module 110 may include one or more sub-modules, and different sub-modules can supply power to different modules in the in-vehicle front view camera module 100. The introduction of this part of the content can be seen below and will not be elaborated here.

[0053] The sensing input module 120 is a module in the in-vehicle front view camera module 100 used to implement the image acquisition function. The sensing input module 120 may include a camera for image acquisition. Optionally, the sensing input module 120 may further include a motion mechanism. The motion mechanism can be used to adjust the viewing range of the camera to obtain images at different positions.

[0054] The introduction of other functions of the sensing input module 120 will not be elaborated here.

[0055] The perception processing module 130 is connected to the perception input module 120, and can acquire the images obtained by the perception input module 120 and process the acquired images, and can also control the perception input module 120. For example, when it is necessary to acquire an image of the vehicle traveling direction, the perception processing module 130 can send an image acquisition instruction to the perception input module 120 to instruct the perception input module 120 to perform image acquisition. For another example, when it is necessary to capture an image at a certain angle, the perception processing module 130 can also send an adjustment instruction to the perception input module 120 to instruct the motion mechanism in the perception input module 120 to adjust the orientation of the camera.

[0056] Optionally, the perception processing module 130 may include a perception chip, and the perception chip may be, for example, a System on Chip (SOC). Optionally, the perception processing module 130 may further include a peripheral circuit and a storage chip.

[0057] In some possible implementation manners, the perception processing module 130 may also control the turn-on and turn-off of the perception input module 120 through the power management module 110. For the introduction of this part of the content, reference can be made to the following text, and details will not be elaborated here.

[0058] The control module 140 can control the perception input module 120 and / or the perception processing module 130. In the embodiments of the present application, the control module 140 can also control the power management module 110 to control the power management module 110 to supply power to one or more modules in the vehicle front view camera module 100, or control the power management module 110 to stop supplying power to one or more modules in the vehicle front view camera module 100.

[0059] Specifically, the control module 140 can communicate with other devices of the vehicle. For example, the control module 140 can communicate with other controllers on the vehicle through the vehicle bus. For example, after the vehicle is started, the control module 140 can obtain a start instruction through the vehicle bus and thus enter the start state.

[0060] For another example, the control module 140 can also acquire a wake-up signal. The wake-up signal is used to wake up the vehicle front view camera module 100. If the wake-up signal is not received, each module in the vehicle front view camera module 100 can be in the off state. The control module 140 can control the power management module 110 not to supply power to the perception input module 120, the perception processing module 130, and the control module 140. After acquiring the wake-up signal, the control module 140 can control the power management module 110 to supply power to the perception input module 120, the perception processing module 130, and the control module 140.

[0061] Optionally, the control module 140 may control the power management module 110 by sending a signal to the power management module 110. For example, the control module 140 may send a General Purpose Input / Output Port (GPIO) signal to the power management module 110 to control the power management module 110.

[0062] Optionally, if the control module 140 controls the power management module 110 to stop powering the sensing input module 120 and the sensing processing module 130, the control module 140 may also send a signal to the sensing input module 120 and / or the sensing processing module 130 to instruct the sensing input module 120 and / or the sensing processing module 130 to shut down. Optionally, the control module 140 may send a Serial Peripheral Interface (SPI) signal to the sensing input module 120 and / or the sensing processing module 130.

[0063] In an embodiment of the present application, the control module 140 may implement the function of turning the vehicle front view camera module 100 into an energy-saving state. Specifically, the control module 140 may obtain an energy-saving state start signal and control the vehicle front view camera module 100 to enter the energy-saving state according to the energy-saving state start signal. The energy-saving state start signal may be triggered by an instruction for the vehicle front view camera module 100 to separately control the vehicle front view camera module 100 to enter the energy-saving state. Or, the energy-saving state start signal may also be an energy-saving state start signal of the entire vehicle for controlling the entire vehicle to enter the energy-saving state.

[0064] Before obtaining the energy-saving state start signal, the vehicle front view camera module 100 is in a working state, and the control module 140 may control the power management module 110 to supply power to the sensing input module 120, the sensing processing module 130, and the control module 140. In this way, since the sensing input module 120, the sensing processing module 130, and the control module 140 are powered normally, the vehicle front view camera module 100 can work properly.

[0065] After obtaining the energy-saving state start signal, the control module 140 may control the vehicle front view camera module 100 to enter the energy-saving state. Specifically, the control module 140 may control the power management module 110 to stop supplying power to the sensing input module 120 and the sensing processing module 130. In this way, since the power management module 110 stops supplying power to the sensing input module 120 and the sensing processing module 130, the sensing input module 120 and the sensing processing module 130 enter the off state. Therefore, the sensing input module 120 and the sensing processing module 130 do not consume electrical energy, achieving the purpose of saving electrical energy.

[0066] Moreover, after receiving the energy-saving state start signal, the control module 140 can also control the power management module 110 to supply power to itself. Since the power management module 110 supplies power to the control module 140, the control module 140 can maintain its working state. In this way, other controllers on the vehicle will not detect that the control module 140 is offline, and thus will not report a fault due to the offline of the control module 140. Moreover, since the control module 140 only needs to control the modules in the in-vehicle front view camera module 100 and does not need to perform complex data processing.

[0067] In this way, by separately managing the power supply states of the control module and other modules, it is possible to stop supplying power to other modules while maintaining the power supply of the control module, thereby reducing the power consumption of the in-vehicle front view camera module.

[0068] This application provides an in-vehicle front view camera module, which may include a power management module, a sensing input module, a sensing processing module, and a control module. Among them, the power management module can supply power to any one or more modules in the in-vehicle front view camera module. The sensing input module includes image acquisition devices such as cameras and related devices for acquiring image data. The sensing processing module can be used to process image information. The control module can control the power management module to supply power to the sensing input module, the sensing processing module, and the control module. Moreover, after receiving the energy-saving state start signal, the control module can control the power management module to stop supplying power to the sensing input module and the sensing processing module according to the energy-saving state start signal, and control the power management module to continue supplying power to the control module. In this way, the sensing input module and the sensing processing module can be turned off through the energy-saving state start signal to reduce the power consumption of the in-vehicle front view camera module. Moreover, since the power supply of the control module itself is maintained, the control module can communicate with other control modules on the vehicle normally and will not cause a fault due to the power-off of the control module. In this way, the power consumption of the in-vehicle front view camera module can be reduced without modifying other modules on the vehicle.

[0069] In some possible implementation manners, the sensing processing module, the sensing input module, and the control module may correspond to different power management sub-modules. Accordingly, the control module can implement the function of switching the in-vehicle front view camera module to the energy-saving state by controlling different power management sub-modules.

[0070] Specifically, as Figure 2 shown, this figure is another implementation manner of the in-vehicle front view camera module adopted in the embodiment of this application. In Figure 2 the shown implementation manner, the in-vehicle front view camera module 200 includes a power management module 210, a sensing input module 220, a sensing processing module 230, and a control module 240.

[0071] For the introduction of the sensing input module 220 and the sensing processing module 230, please refer to Figure 1 the introduction of the corresponding embodiments, which will not be elaborated here.

[0072] In Figure 2 the implementation shown, the power management module 210 includes a first power management sub-module 211 and a second power management sub-module 212. Among them, the first power management sub-module 211 can be used to supply power to the control module 240. The second power management sub-module 212 can be used to supply power to the sensing input module 220 and the sensing processing module 230. The first power management sub-module 211 and the second power management sub-module 212 can be respectively connected to the vehicle power supply for obtaining electrical energy from the vehicle power supply. Optionally, since the first power management sub-module 211 and the second power management sub-module 212 are directly connected to the vehicle power supply, the first power management sub-module 211 and the second power management sub-module 212 can be referred to as primary power management modules.

[0073] The control module 240 can control the first power management sub-module 211 and the second power management sub-module 212 to implement the function of transferring the vehicle front view camera module 200 to the energy-saving state.

[0074] Specifically, before obtaining the energy-saving state start instruction, the control module 240 can control the first power management sub-module 211 to supply power to the control module 240, and control the second power management sub-module 212 to supply power to the sensing input module 220 and the sensing processing module 230. In this way, since the sensing input module 220, the sensing processing module 230 and the control module 240 are all powered on, the vehicle front view camera module 200 can work normally.

[0075] After obtaining the energy-saving state start instruction, the control module 240 can control the first power management sub-module 211 to supply power to the control module 240, and control the second power management sub-module 212 to stop supplying power to the sensing input module 220 and the sensing processing module 230. In this way, since the sensing input module 220 and the sensing processing module 230 are powered off, the power consumption of the vehicle front view camera module 200 is reduced. And since the control module 240 is powered on, other controllers in the vehicle will not give a fault warning due to the offline of the control module 240.

[0076] In this way, the management of different modules in the vehicle front view camera module is realized through different power management sub-modules, and the power supply of the control module can be maintained on the basis of turning off the sensing input module and the sensing processing module.

[0077] In some possible implementation manners, the perception processing module may manage the power-on and power-off of the perception input module. Specifically, the power management module may further include a power management sub-module corresponding to the perception input module. The perception processing module may control the power management sub-module corresponding to the perception input module to control the power-on and power-off of the perception input module.

[0078] For example, in Figure 2 the implementation manner shown, the power management module 210 further includes a third power management sub-module 213. The input end of the third power management sub-module 213 is connected to the output end of the second power management sub-module 212, and the output end of the third power management sub-module 213 is connected to the perception input module 220.

[0079] That is to say, the third power management sub-module 213 is connected to the vehicle-mounted power supply through the second power management sub-module 212. Optionally, the third power management sub-module 213 may also be referred to as a secondary power management sub-module. It can be understood that if the second power management sub-module 212 stops power supply, the third power management sub-module 213 has no power input and cannot supply power to the perception input module 220.

[0080] In an actual scenario, the perception processing module 230 may control the third power management sub-module 213 to control the power-on and power-off of the perception input module 220. Optionally, the perception processing module 230 may control the third power management sub-module 213 through GPIO signals.

[0081] For example, before entering the energy-saving state, the perception processing module 230 may control the third power management sub-module 213 to supply power to the perception input module 220. After entering the energy-saving state, the perception processing module 230 may control the third power management sub-module 213 to stop supplying power to the perception input module 220. Or, in other scenarios where it is necessary to turn off / start the perception input module 220, the perception processing module 230 may control the third power management sub-module 213 to supply power to the perception input module 220, or control the third power management sub-module 213 to stop supplying power to the perception input module 220.

[0082] In this way, through cascaded multi-level power management, the perception processing module 230 controls the perception input module 220.

[0083] The embodiment of the present application further provides a control method for a vehicle-mounted front-view camera module. This method can be used for the control module in the vehicle-mounted front-view camera module. For the introduction of the vehicle-mounted front-view camera module, reference can be made to the above, and details are not described here again.

[0086] S302: In response to obtaining the energy-saving state start signal, control the power management module to stop supplying power to the sensing input module and the sensing processing module, and supply power to the control module.

[0087] In some possible implementation manners, the power management module further includes a third power management sub-module, the second power management sub-module is further used to supply power to the third power management sub-module, and the third power management sub-module is used to supply power to the sensing input module;

[0088] The method further includes: in response to not obtaining the energy-saving state start signal, control the second power management sub-module to supply power to the sensing input module and the sensing processing module; the sensing processing module is used to control the third power management module to supply power to the sensing processing input.

[0090] In response to not obtaining the wake-up signal, control the power management module to stop supplying power to the control module, the sensing input module, and the sensing processing module.
