Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a method, device and vehicle for adjusting vehicle-mounted screen parameters. Background Art

[0002] With the development of technology, in order to meet the growing needs of users, more and more functions are provided in vehicles. For example, the intelligent driving mode of vehicles is becoming more and more mature. Generally, when the vehicle turns on the intelligent driving mode, the vehicle's driving path and other information will be displayed on the instrument screen so that users can clearly see the vehicle's driving information.

[0003] However, various problems may occur in the vehicle under intelligent driving scenarios, and when the vehicle is in an intelligent driving scenario, the driver's safety awareness is low, so the safety of personnel may be affected when the vehicle has problems. Therefore, a method for adjusting the parameters of the vehicle screen that can remind the driver in the intelligent driving mode is urgently needed. Summary of the invention

[0004] The present application provides a method, device, vehicle and storage medium for adjusting the parameters of a vehicle screen, which can adjust the screen parameters of the vehicle screen to more eye-catching parameters when there is a need to take over, realize the linkage control between the intelligent driving mode and the vehicle screen, and enable the vehicle screen to remind the driver to take over the vehicle, so that the driver can deal with the problem in time and ensure driving safety. The technical solution is as follows.

[0005] In a first aspect, a method for adjusting vehicle screen parameters is provided, the method comprising:

[0006] In response to a start-up operation of the intelligent driving mode of the target vehicle, determining whether the target vehicle has a takeover requirement;

[0007] In the case that the target vehicle has a takeover requirement, the screen parameters of the vehicle-mounted screen of the target vehicle are adjusted, and the conspicuity corresponding to the screen parameters after the adjustment of the vehicle-mounted screen is greater than the conspicuity corresponding to the screen parameters before the adjustment.

[0008] In the present application, when the start-up operation of the intelligent driving mode of the target vehicle is received, the start-up operation of the intelligent driving mode of the target vehicle is first responded to to determine whether the target vehicle has a takeover demand. Afterwards, when the target vehicle has a takeover demand, the screen parameters of the vehicle screen are adjusted, and the conspicuousness corresponding to the adjusted screen parameters is greater than the conspicuousness corresponding to the screen parameters before the adjustment. In other words, when the target vehicle has a takeover demand, the vehicle screen is adjusted to be more conspicuous. In this way, the intelligent linkage between the intelligent driving mode and the vehicle screen can be realized, and when the target vehicle has a takeover demand, the screen parameters of the vehicle screen are adjusted to more conspicuous parameters, so that the vehicle screen can serve the purpose of reminding the driver to take over the vehicle, so that the driver can deal with the problem in time and ensure driving safety.

[0009] Optionally, the vehicle-mounted screen includes an intelligent driving information display area, and the method further includes:

[0010] In a case where the target vehicle does not have a takeover requirement, in response to a screen parameter adjustment operation on the vehicle-mounted screen, determining a third screen parameter;

[0011] The screen parameters of other areas on the vehicle-mounted screen except the intelligent driving information display area are adjusted to the third screen parameters.

[0012] In the present application, by adjusting the screen parameters of other areas on the vehicle screen except the intelligent driving information display area to the third screen parameters, the screen parameters of the intelligent driving information display area can be ensured to remain unchanged, so that the driver can still clearly read the intelligent driving information, which is beneficial to driving safety.

[0013] Optionally, the vehicle-mounted screen further includes an entertainment content display area, and the adjusting screen parameters of other areas of the vehicle-mounted screen except the intelligent driving information display area to the third screen parameters includes:

[0014] In a case where entertainment content is displayed in the entertainment content display area, the screen parameters of the entertainment content display area on the in-vehicle screen are adjusted to the third screen parameters.

[0015] In the present application, in the intelligent driving mode, by adjusting the screen parameters of the entertainment content display area on the vehicle screen to the third screen parameters, the driver can freely adjust the screen parameters of the entertainment content display area without taking over the vehicle, thereby improving the user experience.

[0016] Optionally, the in-vehicle screen further includes an entertainment content display area, and the method further includes:

[0017] When the entertainment content display area does not display entertainment content, the screen parameter adjustment operation on the vehicle-mounted screen is not responded to, and the screen parameters of the vehicle-mounted screen are controlled to remain unchanged.

[0018] In this application, when no entertainment content is displayed in the entertainment content display area, the vehicle screen displays the intelligent driving information. In order to ensure that the driver can clearly read the intelligent driving information, the screen parameter adjustment operation of the vehicle screen may not be responded to, so that when no entertainment content is displayed in the entertainment content display area, the screen parameters of the vehicle screen are prohibited from being adjusted, which is conducive to ensuring driving safety.

[0019] Optionally, the method further comprises:

[0020] When the target vehicle does not have a takeover requirement, the screen parameters of the vehicle-mounted screen are adjusted to the first screen parameters.

[0021] In the present application, by adjusting the screen parameters of the vehicle screen to the first screen parameters when there is no need for takeover, the driver can clearly read the content of the intelligent driving information in the intelligent driving mode, thereby improving the driver's driving experience.

[0022] Optionally, the method further comprises:

[0023] In a case where the target vehicle does not have a takeover requirement, in response to a takeover operation on the target vehicle, determining whether the target vehicle exits the intelligent driving mode;

[0024] When the target vehicle exits the smart driving mode, adjusting the screen parameters of the vehicle screen to fourth screen parameters, where the fourth screen parameters are the screen parameters of the vehicle screen before the smart driving mode is turned on;

[0025] When the target vehicle does not exit the intelligent driving mode, the screen parameters of the vehicle-mounted screen are controlled to remain unchanged as the first screen parameters.

[0026] In the present application, when the target vehicle exits the intelligent driving mode, the screen parameters are automatically restored to the fourth screen parameters, and when the target vehicle does not exit the intelligent driving mode, the screen parameters of the vehicle-mounted screen are controlled to remain unchanged as the first screen parameters, so that the screen parameters can be adjusted more intelligently, thereby improving the user experience.

[0027] Optionally, when the target vehicle has a takeover requirement, adjusting screen parameters of an onboard screen of the target vehicle includes:

[0028] In the case where the target vehicle has a takeover requirement, determining whether the target vehicle is taken over;

[0029] When the target vehicle has not been taken over, the screen parameters of the vehicle-mounted screen are adjusted to the second screen parameters.

[0030] In the present application, when the target vehicle has a takeover requirement, it is detected whether the target vehicle has been taken over until the target vehicle is taken over. When it is detected that the target vehicle has not been taken over, the screen parameters are kept as the second screen parameters. In this way, before the target vehicle is taken over, by keeping the screen parameters as the second screen parameters, it can always play the role of reminding the driver to take over the vehicle, which is beneficial to driving safety.

[0031] Optionally, the adjusting the screen parameters of the vehicle-mounted screen of the target vehicle includes at least one of the following:

[0032] Adjusting the color temperature of the vehicle screen to a target color temperature, wherein the target color temperature is the highest color temperature that the vehicle screen can reach;

[0033] Adjusting the contrast of the vehicle-mounted screen to a target contrast, where the target contrast is the maximum contrast that the vehicle-mounted screen can achieve;

[0034] The brightness of the vehicle-mounted screen is adjusted to a target brightness, where the target brightness is the highest brightness that the vehicle-mounted screen can achieve.

[0035] In the present application, if the target vehicle has a takeover demand, the target vehicle may be out of control, and if the target vehicle is not taken over, it may affect the safety of personnel. In addition, when the screen parameters of the vehicle screen include at least one of color temperature, contrast, and brightness, in order to make the light emitted by the vehicle screen more eye-catching, the color temperature of the vehicle screen can be adjusted to the target color temperature, the contrast can be adjusted to the target contrast, and the brightness can be adjusted to the target brightness, so that the vehicle screen displays a clearer takeover demand, thereby achieving the purpose of reminding the driver to take over the vehicle to ensure his own safety, which is conducive to improving driving safety.

[0036] Optionally, the screen parameters of the vehicle-mounted screen include brightness and flickering frequency, and when the target vehicle has a takeover requirement, adjusting the screen parameters of the vehicle-mounted screen of the target vehicle includes:

[0037] When the target vehicle has a takeover requirement, the brightness of the vehicle screen is adjusted to the target brightness and the flashing frequency is adjusted to the target flashing frequency, so that the vehicle screen will subsequently flash at the target brightness and target flashing frequency. The target brightness is the maximum brightness that the vehicle screen can achieve.

[0038] In the present application, the vehicle screen is controlled to flash at a target flashing frequency, and the vehicle screen is displayed at a target brightness when it is on. In this way, the vehicle screen can flash and emit light, thereby achieving the purpose of reminding the driver to take over the vehicle. The driver can then notice the flashing changes of the vehicle screen and read the takeover requirements displayed on the vehicle screen to achieve timely takeover of the target vehicle.

[0039] In a second aspect, a vehicle-mounted screen parameter adjustment device is provided, the device comprising:

[0040] A first determination module is used to determine whether the target vehicle has a takeover requirement in response to the start operation of the intelligent driving mode of the target vehicle;

[0041] The first adjustment module is used to adjust the screen parameters of the vehicle-mounted screen of the target vehicle when the target vehicle has a takeover requirement, and the conspicuity corresponding to the screen parameters of the vehicle-mounted screen after the adjustment is greater than the conspicuity corresponding to the screen parameters before the adjustment.

[0042] In a third aspect, a vehicle is provided, the vehicle comprising:

[0059] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0060] It should be understood that the "multiple" mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of this application, the words "first" and "second" are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not limit them to be different.

[0061] Before describing the vehicle screen parameter adjustment method provided in the embodiment of the present application, the implementation environment involved in the embodiment of the present application is described first.

[0062] For example, Figure 1 Schematic diagram of the implementation environment of a method for adjusting vehicle screen parameters provided by an embodiment of the present application. Figure 1 , Figure 1 The vehicle 101 is comprised, wherein the vehicle 101 may be provided with a vehicle screen 102 and an ADAS (Advanced Driver Assistance Systems) controller 103 .

[0063] The vehicle screen 102 is used to provide functions such as navigation, entertainment, and vehicle information interaction.

[0064] In an embodiment of the present application, the vehicle-mounted screen 102 may be arranged in the front row of the vehicle 101 , and the vehicle-mounted screen 102 may include an instrument screen and / or a central control screen.

[0065] The instrument screen is located in front of the driver's seat and is set up to replace the mechanical pointer instrument of the transmission. It is mainly used to display vehicle speed, rotation speed, fuel level, temperature, alarm prompts and other content. In the intelligent driving mode, the instrument screen can also display information related to intelligent driving, such as the vehicle's driving path, speed, road conditions and other information. Of course, the current instrument screen can also display some entertainment information, such as displaying the song playback interface.

[0066] The central control screen is located in the center of the center console of the vehicle 101, and is mainly used to realize functions such as navigation, entertainment, air conditioning control, menu settings (such as seat heating, steering wheel adjustment), etc. In the intelligent driving mode, the central control screen can also display information related to intelligent driving. For example, when the instrument of the vehicle 101 is a traditional mechanical instrument, information related to intelligent driving can be displayed on the central control screen.

[0067] In the embodiment of the present application, the ADAS controller 103 may be a multifunctional domain controller, which can process data from multiple sensors to implement more complex driving assistance tasks.

[0068] The intelligent driving mode uses advanced sensors (intelligent cameras, laser radars, millimeter-wave radars, etc.), computing platforms, and control algorithms to enable the vehicle 101 to automatically complete operations such as acceleration, deceleration, and steering under certain conditions. Specifically, when the vehicle 101 is in the intelligent driving mode, the ADAS controller can calculate various data to achieve automatic acceleration, deceleration, steering, and other operations.

[0069] Intelligent driving modes are generally divided into five levels, in order from low to high: driver-assisted driving, partially automated driving, conditionally automated driving, highly automated driving, and fully automated driving.

[0070] Driver Assisted Driving refers to the vehicle providing assistance for a single function, such as adaptive cruise control and lane keeping assistance. In the driver assisted driving level, the driver is still in the driving state.

[0071] Partially automated driving allows the vehicle to perform multiple driving tasks simultaneously, such as adaptive cruise control and lane keeping assistance, allowing the vehicle to automatically adjust speed and direction, but partially automated driving still requires the driver to be ready to take over the vehicle at any time.

[0072] Conditional automated driving means that the vehicle can be fully automated under certain conditions, such as remote parking (automatic parking via a mobile phone app), automatically completing most driving tasks on highways, etc. In conditional automated driving, the driver is still required to take over if the vehicle needs it.

[0073] Highly automated driving: The vehicle can drive fully automatically in specific areas or conditions, generally without driver intervention, but requires driver intervention in specific scenarios. For example, when driving on urban roads, it can automatically complete traffic light recognition and pedestrian avoidance.

[0074] Fully automated driving, the vehicle drives completely automatically under all conditions without human intervention, which is equivalent to current driverless cars.

[0075] In the embodiments of the present application, partially automated driving, conditionally automated driving, and highly automated driving are intelligent driving modes that require the driver to take over the vehicle when needed.

[0076] The vehicle 101 may be provided with an opening entry for the intelligent driving mode. For example, the vehicle 101 may be provided with an opening button for the intelligent driving mode, and after the driver clicks the opening button, the intelligent driving mode may be triggered, thereby controlling the vehicle 101 to open the intelligent driving mode.

[0077] It should be understood that the intelligent driving mode includes multiple assisted driving functions. For intelligent driving modes with different functions, the opening entrance of the intelligent driving mode is also different. For example, if the vehicle 101 has a high-speed automatic driving function (a function of automatic driving on a highway), then the vehicle 101 can be provided with an opening entrance for high-speed automatic driving, and the driver can turn on the high-speed automatic driving function by clicking the opening button of the high-speed automatic driving, that is, turning on the intelligent driving mode. For another example, if the vehicle 101 has an automatic parking function, then the driver can turn on the automatic parking function after clicking the opening button of the automatic parking function, that is, turning on the intelligent driving mode.

[0078] In an embodiment of the present application, when the vehicle 101 is in the intelligent driving mode, the above-mentioned vehicle screen 102 can be adjusted accordingly according to the takeover requirements of the vehicle 101, so as to achieve linkage control between the intelligent driving mode and the vehicle screen.

[0079] The application scenarios of the embodiments of the present application are further described.

[0080] Figure 2 Schematic diagram of a scenario of a method for adjusting vehicle screen parameters provided by an embodiment of the present application. Figure 2 , Figure 2 The instrument screen 201 is included, wherein the instrument screen 201 displays the driving information of the vehicle.

[0081] When the driver wants to turn on the smart driving mode, he can find the corresponding smart driving mode in the menu bar on the central control screen. Then, by clicking the smart driving mode start button, the vehicle can turn on the smart driving mode.

[0082] After the smart driving mode is turned on, the instrument screen 201 may display relevant information about the smart driving, such as the lane information of the vehicle, the driving path of the vehicle, and the environment information around the vehicle.

[0083] However, after the driver turns on the intelligent driving mode, their safety awareness will decrease. In addition, the vehicle may not be able to complete automatic decision-making in certain scenarios, and thus cannot perform automatic driving, so the driver needs to take over the vehicle to complete driving. If the driver's safety awareness is low, even if the vehicle displays the takeover information, the driver may not be able to read it in time, so it will cause the problem of not being able to take over the vehicle in time, which will cause unexpected losses and is not conducive to driving safety.

[0084] In addition, sometimes the screen parameters of the car screen are automatically adjusted according to the in-car environment. One disadvantage of this method is that the screen brightness may be relatively low in certain environments, resulting in the driver being unable to read the content displayed on the car screen well.

[0085] To this end, an embodiment of the present application provides a method for adjusting vehicle screen parameters, which can be applied to a scenario where the vehicle is in an intelligent driving mode.

[0086] Specifically, when receiving an operation to turn on the intelligent driving mode of the vehicle, in response to the operation to turn on the intelligent driving mode of the vehicle, it is first determined whether the vehicle has a takeover requirement. If the vehicle has a takeover requirement, the screen parameters of the vehicle screen can be adjusted so that the conspicuity corresponding to the adjusted screen parameters of the vehicle screen is greater than the conspicuity corresponding to the screen parameters before the adjustment.

[0087] In this way, intelligent linkage between the intelligent driving mode and the on-board screen can be achieved, and when the target vehicle has a takeover requirement, the screen parameters of the on-board screen are adjusted to more eye-catching parameters, so that the on-board screen can serve the purpose of reminding the driver to take over the vehicle, so that the driver can deal with the problem in time and ensure driving safety.

[0088] The vehicle-mounted screen parameter adjustment method provided in the embodiment of the present application is explained in detail below.

[0089] Figure 3 1 is a flow chart of a method for adjusting vehicle screen parameters provided by an embodiment of the present application. The method can be applied to a vehicle multimedia head unit (HUT). Figure 3 The method includes the following steps 301-303.

[0090] Step 301: In response to the activation operation of the intelligent driving mode of the target vehicle, the vehicle multimedia host determines whether the target vehicle has a takeover requirement.

[0091] The activation of the intelligent driving mode can be triggered by the driver, for example, the driver can trigger the activation of the intelligent driving mode by clicking, sliding, speaking, or somatosensory operations. As an example, if the driver wants to activate the high-speed automatic driving function, the driver can click the activation button of the high-speed automatic driving function to trigger the activation of the high-speed automatic driving function.

[0092] Optionally, the intelligent driving mode of the target vehicle may include multiple assisted driving functions, such as lane keeping function, high-speed automatic driving function, automatic parking function, traffic congestion assistance function, urban automatic driving function, etc. The driver can choose to turn on all of these functions, or can choose to turn on some of them. It should be understood that as long as one of the multiple assisted driving functions is turned on, it means that the target vehicle has turned on the intelligent driving mode.

[0093] As an example, Figure 4 is a schematic diagram of an intelligent driving mode setting interface provided in an embodiment of the present application. Figure 4 , Figure 4 The intelligent driving mode setting interface 401 is included, wherein a plurality of assisted driving functions are displayed on the intelligent driving mode setting interface 401. Each assisted driving function has a corresponding on button and off button. The driver can click the corresponding on button of the assisted driving function he wants to turn on. It should be understood that if the driver clicks the on button of any one of the plurality of assisted driving functions on the intelligent driving mode setting interface 401, it means that the on operation of the intelligent driving mode of the target vehicle is triggered, and when the driver turns off all assisted driving functions, it can be considered that the intelligent driving mode of the target vehicle is turned off.

[0094] As an implementation method, the ADAS controller of the target vehicle can determine whether the driver needs to take over the vehicle. If the driver needs to take over the vehicle, the ADAS controller can send a message to the on-board multimedia host requiring the driver to take over the target vehicle, so that the on-board multimedia host can determine that the target vehicle has a takeover requirement.

[0095] As another implementation, the vehicle-mounted multimedia host may determine whether the target vehicle has a takeover requirement based on the current driving condition of the target vehicle.

[0096] Specifically, the operation of step 301 may include the following steps (1) to (3).

[0097] (1) In response to the activation operation of the intelligent driving mode of the target vehicle, the vehicle-mounted multimedia host obtains environmental information around the target vehicle, the working status of the sensors of the target vehicle, and the current location of the target vehicle.

[0098] The environmental information may indicate the road conditions around the target vehicle, such as the road environment. Alternatively, the environmental information may be an image of the target vehicle's surroundings collected by a camera of the target vehicle.

[0099] The working state of the sensor of the target vehicle can be a normal working state or a faulty state. Optionally, the sensor of the target vehicle may include sensors used in the intelligent driving mode, such as cameras, radars, etc. In an embodiment of the present application, for each sensor in the target vehicle, a working state flag of the corresponding sensor may be set in the target vehicle, and the working state flag of a sensor may include 0 and 1. When the working flag of a sensor is 0, it is considered that the sensor is working normally. When the working flag of a sensor is 1, it is considered that the working state of the sensor is a faulty state, that is, the sensor is faulty.

[0100] Optionally, the current location of the target vehicle may be acquired through a GPS (Global Positioning System).

[0101] (2) The vehicle multimedia host determines whether the target vehicle is in a complex road condition based on the environmental information, and determines whether the target vehicle exceeds the automatic driving area based on the current location of the target vehicle and a preset area.

[0102] Complex road conditions are roads that include intersections, roundabouts, and construction zones.

[0103] The preset area can be set in advance. The preset area is a safe area where the set intelligent driving mode can work. That is to say, when the vehicle is in the intelligent driving mode, automatic driving may not be completed once it exceeds the preset area.

[0104] Among them, the operation of the on-board multimedia host to determine whether the target vehicle is in a complex road condition based on the environmental information can be: the on-board multimedia host performs target recognition on the environmental information to obtain a target recognition result; when the target recognition result indicates that there is an intersection, roundabout or construction area, the on-board multimedia host determines that the target vehicle is in a complex road condition; when the target recognition result indicates that there is no intersection, roundabout and construction area, the on-board multimedia host determines that the target vehicle is not in a complex road condition.

[0105] The purpose of target recognition is to identify intersections, roundabouts, and construction areas.

[0106] When the target vehicle is in complex road conditions, the sensor fails, or exceeds the preset area, the automatic driving function will be affected, that is, the automatic driving may not be able to complete the automatic task, then the driver needs to take over the vehicle to ensure driving safety. Therefore, the on-board multimedia host can determine whether the target vehicle is in complex road conditions, whether the target vehicle exceeds the automatic driving area, and judge the working status of the sensor based on the environmental information.

[0107] (3) The vehicle-mounted multimedia host determines that the target vehicle has a takeover requirement when the target vehicle is in a complex road condition, or the target vehicle's sensor is in a faulty working state, or the target vehicle is beyond the automatic driving area; the vehicle-mounted multimedia host determines that the target vehicle does not have a takeover requirement when the target vehicle is not in a complex road condition, the target vehicle's sensor is in a normal working state, and the target vehicle has not exceeded the automatic driving area.

[0108] When the target vehicle is in a complex road condition, the ADAS controller may not be able to complete accurate calculations and thus cannot make accurate decisions. Therefore, when the target vehicle is in a complex road condition and the driver is required to take over the vehicle, it can be determined that the target vehicle has a takeover requirement.

[0109] When the working state of the sensor of the target vehicle is a fault state, the target vehicle cannot obtain accurate data, so the ADAS controller cannot complete the accurate calculation task. Therefore, in this case, the driver is also required to take over the vehicle, and it can be determined that the target vehicle has a takeover requirement.

[0110] In the case where the target vehicle exceeds the autonomous driving area, due to the complex environment outside the autonomous driving area, the ADAS controller may not be able to perform effective integrated calculations and thus cannot make accurate decisions. Therefore, when the target vehicle is in complex road conditions and the driver needs to take over the vehicle, the in-vehicle multimedia host can determine that the target vehicle has a takeover requirement.

[0111] When the target vehicle is not in a complex road condition, the sensor is working normally, and the target vehicle has not exceeded the automatic driving area, it means that the target vehicle is in a simple road condition, and the ADAS controller of the target vehicle can obtain relatively accurate data, and can accurately calculate the data, and can make relatively accurate decisions, that is, the ADAS controller can autonomously control the vehicle, so there is no need for the driver to take over the vehicle, then the on-board multimedia host can determine that the target vehicle does not have the need to take over.

[0112] Optionally, when the target vehicle has a takeover requirement, the vehicle multimedia host may also output target reminder information.

[0113] The target reminder message is used to remind the driver that he needs to take over the vehicle at this time. For example, the target reminder message is "Please take over the vehicle immediately."

[0114] In an embodiment of the present application, target reminder information can be output through a vehicle-mounted screen, and the vehicle-mounted screen can be an instrument screen and / or a central control screen.

[0115] For example, Figure 5 is a schematic diagram of a target reminder information interface provided by an embodiment of the present application. Figure 5 , Figure 5 The instrument display interface 501 includes a target reminder information 502, such as Figure 5 As shown, the target reminder information 502 is "Please take over immediately, the vehicle is automatically braking."

[0116] Step 302: When the target vehicle has a takeover requirement, the vehicle multimedia host adjusts the screen parameters of the vehicle screen of the target vehicle, and the conspicuity corresponding to the adjusted screen parameters of the vehicle screen is greater than the conspicuity corresponding to the screen parameters before the adjustment.

[0117] In the embodiment of the present application, the conspicuousness refers to the degree to which the occupants visually or perceptually notice the contents displayed on the screen. A higher conspicuousness means that at this conspicuousness, the contents displayed on the screen are more likely to attract the visual or perceptual attention of the occupants. That is to say, after the in-vehicle screen is adjusted, the contents displayed on the screen are more likely to attract the visual or perceptual attention of the driver.

[0118] When the target vehicle has a takeover demand, it means that the target vehicle cannot make the right decision at this time, that is, the target vehicle may not be able to control itself. If the driver does not take over the vehicle in time, serious consequences may occur. Therefore, in this case, the screen parameters of the vehicle screen can be adjusted to more eye-catching screen parameters.

[0119] In this way, when the target vehicle has a need to take over, the on-board multimedia host adjusts the screen parameters of the on-board screen to more eye-catching screen parameters, so that the on-board screen emits more eye-catching light, so that the light emitted by the on-board screen can serve to remind the driver, and then the driver can take over the vehicle in time to avoid serious consequences, which is conducive to improving driving safety.

[0120] Optionally, the operation of step 302 may be: when the target vehicle has a takeover requirement, the in-vehicle multimedia host adjusts the screen parameters of the in-vehicle screen to the second screen parameters.

[0121] The second screen parameter is a screen parameter corresponding to the vehicle screen when the driver needs to take over the vehicle. The second screen parameter can be set in advance. In the embodiment of the present application, the screen parameter of the vehicle screen may include but is not limited to at least one of the color temperature, contrast, and brightness of the vehicle screen.

[0122] In this case, it is equivalent to that the target vehicle has the preset second screen parameters saved. When it is determined that the target vehicle has a takeover requirement, the vehicle multimedia host can directly adjust the screen parameters of the vehicle screen to the second screen parameters. In this way, the driver can be reminded of the need to take over the vehicle more quickly.

[0123] Optionally, the operation of step 302 may be: when the target vehicle has a takeover requirement, the vehicle multimedia host determines whether the target vehicle is taken over; when the target vehicle is not taken over, the vehicle multimedia host adjusts the screen parameters of the vehicle screen to the second screen parameters.

[0124] In this case, when the target vehicle has a takeover requirement, the vehicle multimedia host keeps detecting whether the target vehicle has been taken over until the target vehicle has been taken over. When it is detected that the target vehicle has not been taken over, the vehicle multimedia host keeps the screen parameters as the second screen parameters. In this way, before the target vehicle is taken over, by keeping the screen parameters as the second screen parameters, the driver can be reminded to take over the vehicle, which is beneficial to driving safety.

[0125] Optionally, when it is determined that the target vehicle has been taken over, the vehicle-mounted multimedia host can determine whether the target vehicle has exited the intelligent driving mode; when the target vehicle has exited the intelligent driving mode, the vehicle-mounted multimedia host adjusts the screen parameters of the vehicle-mounted screen to the fourth screen parameters; when the target vehicle has not exited the intelligent driving mode, the vehicle-mounted multimedia host adjusts the screen parameters of the vehicle-mounted screen to the first screen parameters.

[0126] The first screen parameter is a screen parameter of a vehicle-mounted screen suitable for a user to read intelligent driving information.

[0127] The fourth screen parameter is the screen parameter of the vehicle screen before the intelligent driving mode is turned on.

[0128] The above process is that after the driver takes over the target vehicle, the on-board multimedia host keeps detecting whether the target vehicle has exited the intelligent driving mode. When the target vehicle exits the intelligent driving mode, it means that the driver has solved the predicament of the target vehicle and no longer uses the intelligent driving mode. Therefore, the on-board multimedia host can automatically restore the screen parameters to the screen parameters before the intelligent driving mode is turned on. When the target vehicle has not exited the intelligent driving mode, it means that the driver will continue to use the intelligent driving mode in the future, and the intelligent driving information may still be displayed on the vehicle screen. In order to ensure that the driver can clearly read the intelligent driving information, the on-board multimedia host can adjust the screen parameters to the first screen parameters.

[0129] In this case, when the target vehicle exits the intelligent driving mode, the vehicle multimedia host automatically restores the screen parameters to the fourth screen parameters, and when the target vehicle does not exit the intelligent driving mode, the vehicle multimedia host adjusts the screen parameters of the vehicle screen to the first screen parameters, so that the screen parameters can be adjusted more intelligently, thereby improving the user experience.

[0130] It should be understood that the vehicle-mounted multimedia host can detect whether a shutdown instruction for the auxiliary driving function in the intelligent driving mode is received. When a shutdown instruction for an auxiliary driving function is received, the vehicle-mounted multimedia host can determine that the auxiliary driving function is turned off. In the embodiment of the present application, the vehicle-mounted multimedia host determines that the target vehicle exits the intelligent driving mode when it is determined that all auxiliary driving functions in the intelligent driving mode of the target vehicle are turned off, and determines that the target vehicle does not exit the intelligent driving mode when it is determined that one auxiliary driving function is turned on in the intelligent driving mode of the target vehicle.

[0131] Optionally, when the target vehicle is taken over, the vehicle multimedia host can also adjust the screen parameters of the vehicle screen to the screen parameters set by the driver. When the vehicle screen is used normally, the driver can customize the screen parameters of the vehicle screen. In this case, the vehicle screen can be displayed with the screen parameters customized by the driver.

[0132] Among them, the operation of the on-board multimedia host to determine whether the target vehicle is taken over can be: the on-board multimedia host obtains the current steering wheel torque of the target vehicle; when it is determined that the steering wheel of the target vehicle is held and the current steering wheel torque is greater than or equal to a preset torque threshold, it is determined that the target vehicle is taken over; when it is determined that the steering wheel of the target vehicle is not held or the current steering wheel torque is less than the preset torque threshold, it is determined that the target vehicle is not taken over.

[0133] The preset torque threshold value can be set in advance and can be set relatively large. In the embodiment of the present application, the preset torque threshold value can also be set according to the minimum steering wheel torque applied by the driver when driving the vehicle normally.

[0134] It should be understood that the steering wheel of the target vehicle may be arranged with a hand grip detection sensor, a pressure sensor or an infrared sensor, etc.

[0135] The hand grip detection sensor can be a capacitive or resistive touch sensor installed on the surface of the steering wheel. When the driver's hand touches the steering wheel, the touch sensor detects a change in capacitance or resistance, thereby determining that the steering wheel is being gripped.

[0136] Or it can be detected by a pressure sensor installed on the surface of the steering wheel. When the driver holds the steering wheel, the pressure sensor detects the pressure change and determines that the steering wheel is held.

[0137] Or it can be detected by an infrared sensor installed around the steering wheel. When the driver's hand approaches or touches the steering wheel, the infrared sensor can detect the increase in temperature or the approach of an object, thereby determining that the steering wheel is being held.

[0138] The above-mentioned hand grip detection sensor, pressure sensor or infrared sensor can detect corresponding changes in capacitance or resistance, pressure changes or temperature changes. Then the vehicle-mounted multimedia host can obtain the changes in capacitance or resistance, pressure changes or temperature changes detected by the hand grip detection sensor, pressure sensor or infrared sensor, and determine whether the steering wheel is held based on the changes in capacitance or resistance, pressure changes or temperature changes.

[0139] When the driver is driving a vehicle, he needs to hold the steering wheel with his hands and may need to apply corresponding force to stabilize the steering wheel. In addition, in some complex scenarios, operations such as steering may be required. At this time, the driver will apply corresponding force to the steering wheel, so the steering wheel torque will increase accordingly. Therefore, in this case, whether the target vehicle takes over can be determined based on whether the steering wheel is held and the current steering wheel torque.

[0140] When the steering wheel of the target vehicle is held and the current steering wheel torque is greater than or equal to the preset torque threshold, it means that the driver is holding the steering wheel at this time, and the current steering wheel torque is large, greater than or equal to the minimum steering wheel torque applied by the driver when driving the vehicle normally, which means that the driver is holding the steering wheel and applying a certain force to the steering wheel, which means that the driver is driving the vehicle. In this case, the on-board multimedia host can determine that the target vehicle has been taken over.

[0141] In the case where the steering wheel of the target vehicle is not held, it means that the driver is not holding the steering wheel at this time, so it can be directly determined that the driver is not driving the vehicle, so that the in-vehicle multimedia host can determine that the target vehicle has not been taken over.

[0142] When the current steering wheel torque of the target vehicle is less than the preset torque threshold, it means that the current steering wheel torque of the target vehicle is small, which is less than the minimum steering wheel torque applied by the driver during normal driving of the vehicle. In addition, in the intelligent driving mode, the steering wheel may have a small steering wheel torque, so in this case, the vehicle multimedia host can also determine that the target vehicle has not been taken over.

[0143] Optionally, the vehicle-mounted multimedia host can also detect whether the accelerator / accelerator pedal or the brake pedal is stepped on; if it is detected that the accelerator / accelerator pedal or the brake pedal is stepped on, it is determined that the target vehicle is taken over; if it is detected that the accelerator / accelerator pedal or the brake pedal is not stepped on, it is determined that the target vehicle is not taken over.

[0144] After the driver takes over the target vehicle, he needs to keep the target vehicle running normally, so the driver may step on the accelerator / electric pedal or the brake pedal. Therefore, it can be judged whether the target vehicle has been taken over, and it can be accurately determined whether the target vehicle has been taken over.

[0145] Among them, the operation of the on-board multimedia host to detect whether the accelerator / accelerator pedal or the brake pedal is stepped on can be: the on-board multimedia host obtains the pedal opening of the accelerator / accelerator pedal or the brake pedal; the on-board multimedia host determines that the accelerator / accelerator pedal or the brake pedal is stepped on when the pedal opening of the accelerator / accelerator pedal or the brake pedal is greater than or equal to a preset opening threshold; when the pedal opening of the accelerator / accelerator pedal or the brake pedal is less than the preset opening threshold, the on-board multimedia host determines that the accelerator / accelerator pedal or the brake pedal is not stepped on.

[0146] It is worth noting that when the screen parameters of the vehicle-mounted screen include at least one of color temperature, contrast, and brightness, the second screen parameters may include at least one of target color temperature, target contrast, and target brightness.

[0147] In this case, the operation of the in-vehicle multimedia host adjusting the screen parameters of the in-vehicle screen to the second screen parameters may include at least one of the following.

[0148] First, the in-vehicle multimedia host adjusts the color temperature of the in-vehicle screen to the target color temperature.

[0149] The target color temperature is the highest color temperature that the car screen can achieve.

[0150] Color temperature is a standard for measuring the color of light sources. Common color temperatures range from warm tones (low color temperature, such as 2700K (Kelvin)) to cool tones (high color temperature, such as 6500K or higher). Usually, light with low color temperature is yellowish or orange, which is relatively soft. Therefore, in terms of conspicuousness, low color temperature is not very conspicuous and is not easy to attract strong visual attention. Light with high color temperature is blue or white, especially in a darker environment, and high color temperature will appear more dazzling and obvious, so it is more eye-catching.

[0151] In the case that the target vehicle has a takeover requirement, the target vehicle may be out of control, and if the target vehicle is not taken over, it may affect the safety of personnel. In addition, in the case that the screen parameters of the vehicle screen include color temperature, in order to remind the driver through the vehicle screen, the vehicle multimedia host can adjust the color temperature of the vehicle screen to the target color temperature, so that the content displayed on the vehicle screen is more eye-catching, so as to achieve the purpose of reminding the driver to take over the target vehicle.

[0152] Second, the vehicle multimedia host adjusts the contrast of the vehicle screen to the target contrast.

[0153] The target contrast is the maximum contrast that can be achieved by the vehicle screen.

[0154] Contrast refers to the difference in brightness between the brightest and darkest areas on the screen. High contrast means that black is blacker, white is whiter, black and white are in strong contrast, and colors are bright, so that the image has a stronger sense of hierarchy. From the perspective of eye-catchingness, it is more eye-catching and easy to attract visual attention. When the screen displays with low contrast, it lacks a sense of hierarchy and is usually not very eye-catching because the colors are not bright enough to attract attention.

[0155] In the case that the target vehicle has a takeover requirement, the target vehicle may be out of control, and if the target vehicle is not taken over, it may affect the safety of personnel. In addition, when the screen parameters of the vehicle screen include contrast, in order to make the light emitted by the vehicle screen more eye-catching, the vehicle multimedia host can adjust the contrast of the vehicle screen to the target contrast, so that the vehicle screen emits brightly colored light, so that the vehicle screen shows a clearer takeover requirement, thereby achieving the purpose of reminding the driver to take over the vehicle.

[0156] Third, the vehicle multimedia host adjusts the brightness of the vehicle screen to the target brightness.

[0157] The target brightness is the maximum brightness that the vehicle screen can achieve.

[0158] Generally, the higher the screen brightness, the clearer the content displayed on the screen. Therefore, when the target vehicle has a takeover requirement, the in-vehicle multimedia host can adjust the brightness of the in-vehicle screen to the target brightness, so that the in-vehicle screen displays a clearer takeover requirement, thereby achieving the purpose of reminding the driver to take over the vehicle to ensure his own safety.

[0159] It should be noted that when the screen parameters of the vehicle screen include at least one of color temperature, contrast, and brightness, the screen parameters can be adjusted in at least one of the above three ways. For example, when the screen parameters of the vehicle screen include color temperature, contrast, and brightness, the screen parameters can be adjusted in a comprehensive manner using the above three ways.

[0160] In this case, it is equivalent to that the vehicle multimedia host uses at least one of the above methods to make the vehicle screen always display with the adjusted screen parameters, that is, to control the vehicle screen to always display with the highest color temperature, highest contrast, and highest brightness.

[0161] Optionally, the screen parameters of the vehicle-mounted screen may also include a flickering frequency.

[0162] Optionally, when the target vehicle has a takeover requirement, the vehicle multimedia host adjusts the brightness of the vehicle screen to the target brightness and the flickering frequency to the target flickering frequency, so that the subsequent vehicle screen flashes at the target brightness and target flickering frequency.

[0163] In this case, the vehicle multimedia host controls the vehicle screen to flash at the target flashing frequency, and displays at the target brightness when the vehicle screen is on. In this way, the vehicle screen can flash and emit light, thereby achieving the purpose of reminding the driver to take over the vehicle. The driver can then notice the flashing changes of the vehicle screen and read the takeover requirements displayed on the vehicle screen to achieve timely takeover of the target vehicle.

[0164] Optionally, when the screen parameters of the vehicle screen include color temperature, contrast, brightness and flicker frequency, the vehicle multimedia host may also execute the following screen parameter adjustment strategy.

[0165] When the target vehicle has a takeover requirement, the vehicle multimedia host can control the vehicle screen to flash at the target color temperature, target contrast, target brightness and target flashing frequency.

[0166] In this case, it is equivalent to the vehicle multimedia host controlling the vehicle screen to flash and illuminate at the maximum screen parameters, so as to achieve the maximum conspicuity of the screen, allowing the driver to more easily notice the flashing changes of the vehicle screen, thereby achieving the purpose of reminding the driver to take over the target vehicle as soon as possible.

[0167] Optionally, when the target vehicle has a takeover requirement, the vehicle-mounted multimedia host can adjust the screen parameters of the vehicle-mounted screen by at least one of the three methods mentioned above, and can also determine whether the target vehicle has been taken over within the target time length; if the target vehicle has not been taken over within the target time length, the vehicle-mounted screen is controlled to flash with the target color temperature, target contrast, target brightness and target flashing frequency.

[0168] The target duration can be set in advance, and the target duration can be set smaller.

[0169] In this case, it is equivalent to judging whether the driver takes over the target vehicle in time. If the target vehicle is not taken over in time, the on-board multimedia host will further adjust the on-board screen parameters to the most eye-catching screen parameters, thereby reminding the driver to take over the target vehicle as soon as possible, thereby ensuring the safety of personnel, which is conducive to driving safety.

[0170] It should be noted that the in-vehicle multimedia host does not respond to parameter adjustment operations on the in-vehicle screen when the target vehicle has a takeover requirement.

[0171] Since the target vehicle may be out of control when the target vehicle needs to be taken over, the driver may need to perform emergency operations after taking over the target vehicle. In this case, if the screen parameters of the vehicle screen are adjusted, it may disturb the driver's vision, resulting in serious consequences. Therefore, it is prohibited to adjust the screen parameters of the vehicle screen when the target vehicle needs to be taken over.

[0172] In this way, when the target vehicle has a takeover demand, it is prohibited to adjust the screen parameters of the vehicle-mounted screen, so that the driver can concentrate on taking over the target vehicle and driving the target vehicle, which is beneficial to driving safety.

[0173] The above describes the specific control strategy for the vehicle-mounted screen when the target vehicle has a takeover requirement. The following describes the specific control strategy for the vehicle-mounted screen when the target vehicle does not have a takeover requirement.

[0174] Optionally, when the target vehicle does not have a takeover requirement, the in-vehicle multimedia host adjusts the screen parameters of the in-vehicle screen to the first screen parameters.

[0175] The first screen parameter is a screen parameter suitable for users to read the intelligent driving information, that is, when the vehicle screen displays with the first screen parameter, the intelligent driving information can be clearly displayed, so that the user can clearly read the intelligent driving information.

[0176] If the target vehicle does not need to take over, it means that the ADAS controller of the target vehicle can make the right decision based on various data. Therefore, in this case, the driver does not need to take over the vehicle. However, when the intelligent driving mode is turned on, the driver is also required to monitor the entire automatic driving process at all times, so the driver needs to read the intelligent driving information on the in-vehicle screen.

[0177] In this way, by adjusting the screen parameters of the vehicle-mounted screen to the first screen parameters, the driver can clearly read the content of the intelligent driving information in the intelligent driving mode, thereby improving the driver's driving experience.

[0178] As an implementation method, the first screen parameter can be set by the driver. For example, a parameter configuration interface of the intelligent driving mode can be set on the vehicle screen, and the driver can configure the screen parameters of the vehicle screen in the intelligent driving mode through the parameter configuration interface of the intelligent driving mode, thereby subsequently realizing the linkage control between the intelligent driving mode and the vehicle screen.

[0179] For example, Figure 6 is a schematic diagram of a parameter configuration interface provided in an embodiment of the present application, see Figure 6 , Figure 6The parameter configuration interface 601 includes a screen parameter configuration area 602. Figure 6 The contents that can be configured in the parameter configuration interface are merely exemplified and described. The contents can be set based on the screen parameters actually included in the vehicle screen, and the embodiments of the present application do not limit this.

[0180] like Figure 6 As shown, in the screen parameter configuration area 604, the driver can configure the color temperature, contrast, brightness and other parameters of the vehicle screen by clicking, sliding and the like.

[0181] As another implementation, the in-vehicle multimedia host may determine the first screen parameter based on environmental information in the target vehicle.

[0182] The environmental information is used to represent the driving environment of the driver. Optionally, the environmental information may include the light intensity in the target vehicle.

[0183] Optionally, a light sensor may be installed in the target vehicle, so the light intensity in the target vehicle may be collected by the light sensor and sent to the vehicle-mounted multimedia host.

[0184] Then the specific operation of the vehicle multimedia host determining the first screen parameter based on the environmental information in the target vehicle may be: the vehicle multimedia host obtains the corresponding screen parameter from the first corresponding relationship based on the light intensity in the target vehicle and determines it as the first screen parameter.

[0185] The first correspondence is the correspondence between the light intensity and the screen parameters in the intelligent driving mode. The first correspondence includes multiple light intensities and multiple screen parameters, wherein the multiple light intensities correspond to the multiple screen parameters one by one, that is, for each light intensity, there is a corresponding screen parameter suitable for the driver to read the intelligent driving information.

[0186] Optionally, the first corresponding relationship can be set in advance. In an embodiment of the present application, the first corresponding relationship can be calibrated in advance by a technician. Specifically, by controlling the vehicle to be in different light intensities, and then adjusting the screen parameters of the vehicle screen, a screen parameter suitable for the driver to read the intelligent driving information is selected from the screen parameters adjusted multiple times as a screen parameter corresponding to a light intensity. In this way, screen parameters corresponding to different light intensities can be obtained, and they are screen parameters suitable for the driver to read the intelligent driving information corresponding to different light intensities.

[0187] In this case, by pre-calibrating the first corresponding relationship, after the vehicle starts the intelligent driving mode, the on-board multimedia host can quickly determine the first screen parameters, so that the screen parameters of the on-board screen can be quickly adjusted to the first screen parameters, thereby improving the efficiency of the on-board multimedia host in adjusting the screen parameters.

[0188] It is worth noting that in the embodiment of the present application, different adjustments to the screen parameters of different areas on the vehicle screen are supported, that is, different screen parameters can be set for different areas.

[0189] Generally, the vehicle screen may include a backlight, which can adjust the brightness of the vehicle screen by emitting light with different powers. In the embodiment of the present application, the backlight of the vehicle screen is divided into multiple independent areas, and the multiple independent areas are controlled separately, so that the brightness of each area can be adjusted independently.

[0190] Optionally, the in-vehicle screen may include an intelligent driving information display area.

[0191] The intelligent driving information display area is the area on the vehicle screen used to display relevant intelligent driving information in intelligent driving mode.

[0192] In this case, when the target vehicle does not have a takeover requirement, the vehicle multimedia host determines the third screen parameters in response to the screen parameter adjustment operation of the vehicle screen; and adjusts the screen parameters of other areas on the vehicle screen except the intelligent driving information display area to the third screen parameters.

[0193] The screen parameter adjustment operation is used to adjust the screen parameters of the vehicle screen. As an example, the driver can adjust the screen parameters of the vehicle screen in the above parameter configuration interface.

[0194] The third screen parameter is the screen parameter adjusted by the driver after the smart driving mode is turned on. In some embodiments, when the target vehicle does not have a takeover requirement, the screen parameter of the vehicle screen is first adjusted to the first screen parameter, and then the driver can adjust the screen parameter when the first screen parameter is not met, so that the screen parameter can be adjusted to the third screen parameter. Of course, when the target vehicle does not have a takeover requirement, the driver can directly configure the screen parameter so that the screen parameter is adjusted to the third screen parameter, and the embodiment of the present application does not specifically limit this.

[0195] Since in the intelligent driving mode, the driver may need to monitor the in-vehicle screen all the time to read relevant information about intelligent driving, and the first screen parameter is a screen parameter suitable for the driver to read the intelligent driving information. Consider a situation where the in-vehicle screen may become dim after being displayed with the third screen parameter, which will be detrimental to the driver reading the intelligent driving information. Therefore, the screen parameters of other areas except the intelligent driving information display area can be adjusted to the third screen parameter.

[0196] In this case, by adjusting the screen parameters of other areas on the vehicle screen except the intelligent driving information display area to the third screen parameters, the screen parameters of the intelligent driving information display area can be ensured to remain unchanged, so that the driver can still clearly read the intelligent driving information, which is beneficial to driving safety.

[0197] Optionally, the in-vehicle screen may also include an entertainment content display area. In this case, the in-vehicle screen includes an intelligent driving information display area and an entertainment content display area.

[0198] The entertainment content display area is an area for displaying entertainment information, such as music playing information, audio book playing information, etc.

[0199] In this case, the operation of the vehicle multimedia host adjusting the screen parameters of other areas on the vehicle screen except the intelligent driving information display area to the third screen parameters can be: when the vehicle multimedia host displays entertainment content in the entertainment content display area, the screen parameters of the entertainment content display area on the vehicle screen are adjusted to the third screen parameters.

[0200] Since the content displayed in the entertainment content display area will not affect the intelligent driving process, even if the screen parameters of the entertainment content display area are adjusted, it will not affect the driver's reading of the intelligent driving information.

[0201] In this case, in the intelligent driving mode, the vehicle multimedia host adjusts the screen parameters of the entertainment content display area on the vehicle screen to the third screen parameters, so that the driver can freely adjust the screen parameters of the entertainment content display area without taking over the vehicle, thereby improving the user experience.

[0202] Optionally, when the vehicle-mounted multimedia host receives a screen parameter adjustment operation for the vehicle-mounted screen, if the entertainment content display area does not display entertainment content, it does not respond to the screen parameter adjustment operation for the vehicle-mounted screen and controls the screen parameters of the vehicle-mounted screen to remain unchanged.

[0203] Since the in-vehicle screen includes an intelligent driving information display area and an entertainment content display area, when the entertainment content display area does not display entertainment content, the in-vehicle screen displays the intelligent driving information. In this case, in order to ensure that the driver can clearly read the intelligent driving information, the in-vehicle multimedia host may not respond to the screen parameter adjustment operation of the in-vehicle screen, thereby prohibiting the adjustment of the screen parameters of the in-vehicle screen when the entertainment content is not displayed in the entertainment content display area, which is conducive to ensuring driving safety.

[0204] For example, Figure 7 1 is a schematic diagram of an in-vehicle screen display interface provided by an embodiment of the present application, and is described by taking the in-vehicle screen as an instrument screen as an example. Figure 7 , Figure 7 The instrument screen display interface 701 includes an intelligent driving information display interface 702 and an entertainment content display area 703. The instrument screen display interface 701 refers to the instrument screen display interface in the intelligent driving mode. Figure 7 As shown, the intelligent driving information display interface 702 displays intelligent driving information, and the entertainment content display area 703 displays music playback information.

[0205] After receiving the screen parameter adjustment operation for the vehicle screen, the vehicle multimedia host first determines whether entertainment information is displayed in the entertainment content display area 703. Figure 7 As shown, music playing information is displayed in the entertainment content display area 703 , and the in-vehicle multimedia host can adjust the screen parameters of the entertainment content display area 703 on the in-vehicle screen to the third screen parameters in response to the screen parameter adjustment operation on the in-vehicle screen.

[0206] Optionally, the above adjustment of screen parameters of different areas on the vehicle screen may be adjustment of screen brightness of different areas. For example, when the vehicle multimedia host adjusts the screen parameters of the entertainment content display area, the screen parameters of the entertainment content display area may be adjusted by adjusting the power of the backlight of the vehicle screen corresponding to the entertainment content display area.

[0207] In some cases, although the target vehicle does not have a takeover requirement, the driver may still take over the vehicle. In this case, the screen parameters of the vehicle screen will also change accordingly.

[0208] Specifically, when the target vehicle does not have a takeover requirement, the vehicle-mounted multimedia host detects whether the target vehicle has exited the intelligent driving mode in response to a takeover operation on the target vehicle; when the target vehicle has exited the intelligent driving mode, the screen parameters of the vehicle-mounted screen are adjusted to the fourth screen parameters; when the target vehicle has not exited the intelligent driving mode, the screen parameters of the vehicle-mounted screen are controlled to remain unchanged as the first screen parameters.

[0209] The takeover operation of the target vehicle may be an operation of the driver turning the steering wheel of the target vehicle, stepping on the brake pedal, or stepping on the accelerator pedal.

[0210] The above process is: after the driver takes over the target vehicle, it is constantly checking whether the target vehicle has exited the intelligent driving mode. When the target vehicle exits the intelligent driving mode, the intelligent driving information will not be displayed on the vehicle screen, so there is no need to adjust the screen parameters of the vehicle screen to the first screen parameters. Therefore, the screen parameters can be automatically restored to the screen parameters before the intelligent driving mode is turned on. When the target vehicle has not exited the intelligent driving mode, it means that the intelligent driving information may still be displayed on the vehicle screen. In order to ensure that the driver can clearly read the intelligent driving information, the screen parameters can be kept unchanged as the first screen parameters.

[0211] In this case, when the target vehicle exits the intelligent driving mode, the screen parameters are automatically restored to the fourth screen parameters, and when the target vehicle does not exit the intelligent driving mode, the screen parameters of the vehicle screen are controlled to remain unchanged as the first screen parameters, so that the screen parameters can be adjusted more intelligently, thereby improving the user experience.

[0212] It is worth noting that in the embodiment of the present application, the adjustment strategy of the screen parameters of the vehicle-mounted screen by the vehicle-mounted multimedia host when the target vehicle has a takeover requirement is different from the adjustment strategy of the screen parameters of the vehicle-mounted screen by the vehicle-mounted multimedia host when the target vehicle does not have a takeover requirement, thereby realizing the intelligent linkage between the intelligent driving mode and the vehicle-mounted screen.

[0213] For ease of understanding, now combined Figure 8 The method for adjusting the parameters of the vehicle screen provided in the embodiment of the present application is exemplified. For example, Figure 8 is a flow chart of another method for adjusting vehicle screen parameters provided by an embodiment of the present application. Figure 8 , Figure 8 The process includes steps 801 to 808.

[0214] Step 801: The target vehicle starts the intelligent driving mode.

[0215] Step 802: The vehicle multimedia host determines whether the target vehicle has a takeover requirement. If the target vehicle does not have a takeover requirement, the following steps 803 to 806 are executed. If the target vehicle has a takeover requirement, the following steps 807 to 808 are executed.

[0216] Step 803: When the target vehicle does not have a takeover requirement, the in-vehicle multimedia host adjusts the screen parameters of the in-vehicle screen to the first screen parameters.

[0217] Step 804: The vehicle multimedia host determines whether the target vehicle has been taken over. If the target vehicle has not been taken over, return to step 803 to continue to keep the first screen parameters unchanged. If the target vehicle has been taken over, execute the following step 805.

[0218] Step 805: The vehicle multimedia host determines whether the target vehicle exits the smart driving mode. If the target vehicle exits the smart driving mode, the vehicle multimedia host executes the following step 806. If the target vehicle does not exit the smart driving mode, the vehicle multimedia host returns to execute step 803 to continue to keep the first screen parameters unchanged.

[0219] Step 806: The in-vehicle multimedia host adjusts the screen parameters of the in-vehicle screen to the fourth screen parameters.

[0220] Step 807: The vehicle multimedia host determines whether the target vehicle is taken over if the target vehicle has a takeover requirement. If the target vehicle is taken over, the above step 805 is executed. If the target vehicle is not taken over, the following step 808 is executed.

[0221] Step 808: The in-vehicle multimedia host adjusts the screen parameters of the in-vehicle screen to the second screen parameters.

[0222] In an embodiment of the present application, when the vehicle-mounted multimedia host receives the start-up operation of the intelligent driving mode of the target vehicle, it first responds to the start-up operation of the intelligent driving mode of the target vehicle to determine whether the target vehicle has a takeover requirement. Afterwards, when the target vehicle has a takeover requirement, the screen parameters of the vehicle-mounted screen are adjusted, and the conspicuousness corresponding to the adjusted screen parameters is greater than the conspicuousness corresponding to the screen parameters before the adjustment. In other words, when the target vehicle has a takeover requirement, the vehicle-mounted screen is adjusted to be more conspicuous. In this way, the intelligent linkage between the intelligent driving mode and the vehicle-mounted screen can be achieved, and when the target vehicle has a takeover requirement, the screen parameters of the vehicle-mounted screen are adjusted to more conspicuous parameters, so that the vehicle-mounted screen can serve the purpose of reminding the driver to take over the vehicle, so that the driver can deal with the problem in time and ensure driving safety.

[0223] Fig. 91 is a schematic diagram of the structure of a vehicle-mounted screen parameter adjustment device provided in an embodiment of the present application.
