Description

Technical Field

[0001] The present application relates to the field of vehicle lamp control, and more specifically, to a vehicle logo control method, apparatus, and vehicle in the field of vehicle lamp control. Background Art

[0002] With the popularization of automobiles, people's requirements for vehicle lamps are getting higher and higher. Vehicle lamps not only need to have specific lighting functions, but also many additional vehicle lamps with decorative functions are added. For example, the vehicle logo not only serves to identify the vehicle brand, but can also be lit in specific scenarios and has a lighting function.

[0003] Currently, in order to implement the dynamic lighting function of the vehicle logo, it is often necessary to add an additional vehicle logo controller (MCU) to achieve the dynamic lighting of the vehicle logo. However, adding an additional vehicle logo controller will obviously increase the control cost of the vehicle. Summary of the Invention

[0004] The present application provides a vehicle logo control method, apparatus, and vehicle. The method can achieve the control of the vehicle logo while reducing the control cost of the vehicle logo.

[0005] In a first aspect, a vehicle logo control method is provided. The method is applied to a combined headlamp controller of a vehicle. The vehicle further includes a position lamp and a vehicle logo. The method includes:

[0006] The vehicle logo is connected to the combined headlamp controller through a first transmission line, and the position lamp is connected to the combined headlamp controller through a second transmission line;

[0007] If the vehicle logo meets the preset requirements of the position lamp, when the combined headlamp controller receives a position lamp lighting signal, control to light the position lamp and the vehicle logo;

[0008] If the vehicle logo does not meet the preset requirements of the position lamp, when the position lamp is in a lit state and the combined headlamp controller detects that the vehicle state meets a preset condition, control to light the vehicle logo.

[0009] In the above technical solution, a control method for a vehicle logo is proposed: by connecting the vehicle logo to the combined headlight controller, the original combined headlight controller in the vehicle is reused to achieve dynamic control of the vehicle logo; in addition, considering that the vehicle logo needs to meet specific regulatory requirements when it is lit, different lighting scenarios are provided for the vehicle logo according to whether the vehicle logo meets the preset requirements of the position light: when the vehicle logo meets the preset requirements of the position light, the position light and the vehicle logo can be controlled to be lit through the position light lighting signal, so that the vehicle logo participates in the position light function; when the vehicle logo does not meet the preset requirements of the position light, if the position light is lit, after the combined headlight controller determines that other vehicle states meet the preset conditions, the vehicle logo is controlled to be lit, so that the vehicle logo is lit under the condition of meeting the regulatory requirements.

[0010] In combination with the first aspect, in some possible implementation manners, the controlling to light the vehicle logo when the position light is in the lit state and the combined headlight controller detects that the vehicle state meets the preset conditions includes: when the position light is in the lit state, obtaining the vehicle speed, vehicle gear, and vehicle speed attribute of the vehicle, where the vehicle speed attribute is used to indicate whether the vehicle speed is valid; when the combined headlight controller detects that the vehicle speed is less than the speed threshold, the vehicle gear is in the parking gear, and the vehicle speed attribute indicates that the vehicle speed is valid, controlling to light the vehicle logo.

[0011] In combination with the first aspect and the above implementation manners, in some possible implementation manners, the method further includes: when the vehicle logo is in the lit state and the combined headlight controller detects that the position light is extinguished, controlling the vehicle logo to be extinguished; or, when the vehicle logo is in the lit state and the combined headlight controller detects that the vehicle speed is greater than the speed threshold, controlling the vehicle logo to be extinguished; or, when the vehicle logo is in the lit state and the combined headlight controller detects that the vehicle gear is not in the parking gear, controlling the vehicle logo to be extinguished; or, when the vehicle logo is in the lit state and the combined headlight controller detects that the vehicle speed attribute indicates that the vehicle speed is invalid, controlling the vehicle logo to be extinguished.

[0012] In the above technical solution, considering that the vehicle logo cannot participate in the position light function when the vehicle logo does not meet the preset requirements of the position light, in order to provide a lighting scenario for the vehicle logo under the condition of meeting the regulatory requirements, the present application also proposes to automatically control to light the vehicle logo when the position light is lit, the vehicle speed is valid, the vehicle speed is less than the speed threshold (stationary state), and the vehicle is in the parking gear, so that the vehicle logo participates in the parking lighting function, and the vehicle logo is lit in the parking scenario under the condition of meeting the regulatory requirements; in addition, if the combined headlight controller determines that any one of the position light, vehicle speed, vehicle speed attribute, and gear does not meet the requirements, it is necessary to timely control the vehicle logo to be extinguished.

[0013] Combined with the first aspect and the above implementation manners, in some possible implementation manners, if the vehicle logo meets the preset requirements of the position lights, after the combined headlight controller receives the position light lighting signal and controls the position lights and the vehicle logo to be lit, the method further includes: when the combined headlight controller receives the position light extinguishing signal, controlling the position lights and the vehicle logo to be extinguished.

[0014] In the above technical solution, when the vehicle logo meets the preset requirements of the position lights, the vehicle logo belongs to a part of the position lights. Then, after the vehicle logo is lit along with the position lights, it is also necessary to control the vehicle logo to be extinguished along with the extinguishing of the position lights. The present application also proposes that when the combined headlight controller receives the position light extinguishing signal, the position lights and the vehicle logo can be controlled to be extinguished simultaneously, so as to enable the vehicle logo to participate in the position light function.

[0015] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the method further includes: if the vehicle logo meets the preset requirements of the position lights, when the combined headlight controller receives the target light language signal, controlling the position lights and the vehicle logo to jointly display the target animation, where the target light language signal at least includes an unlocking light language signal or a locking light language signal; when the combined headlight controller receives the light language stop signal, controlling the position lights and the vehicle logo to stop displaying the target animation.

[0016] In the above technical solution, in order to achieve the dynamic lighting effect of the vehicle logo, the present application also proposes that the vehicle logo participates in the position light light language function, that is, the combined headlight controller can, after receiving the target light language signal, control the position lights and the vehicle logo to jointly display the target animation indicated by the target light language signal, so as to achieve the dynamic lighting effect of the vehicle logo; similarly, after the combined headlight controller receives the light language stop signal, it will also correspondingly control the position lights and the vehicle logo to stop displaying the target animation.

[0017] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the method further includes: when the position lights and the vehicle logo jointly display the target animation, detecting the component states of the respective light-emitting components participating in the display of the target animation, where the component states include a fault state or a normal state; when the fault ratio is greater than the ratio threshold, controlling the position lights and the vehicle logo to stop displaying the target animation, where the fault ratio is the ratio of the light-emitting components in the fault state among the light-emitting components.

[0018] In the above technical solution, both the vehicle logo and the position lamp are composed of light-emitting components to achieve lighting. During the process of displaying the target animation, considering the situation of light-emitting component failure, when the combined headlamp controller detects that the failure ratio is greater than the ratio threshold and affects the display of the target animation, it will control the position lamp and the vehicle logo to stop displaying the animation, avoiding invalid animation display operations in case of failure.

[0019] Combined with the first aspect and the above implementation, in some possible implementations, the combined headlamp controller controls the power supply of the vehicle to supply power to the vehicle logo through a target switch.

[0020] In the above technical solution, by adding a target switch to control the power supply to the vehicle logo, the situation of the vehicle logo being constantly on due to abnormal power feed can be avoided, and thus the waste of vehicle power consumption caused by the constantly-on vehicle logo can be avoided.

[0021] Combined with the first aspect and the above implementation, in some possible implementations, the vehicle further includes a parking lamp, and the method further includes: when the combined headlamp controller receives a parking lamp lighting signal, controlling to light the parking lamp and the vehicle logo; when the combined headlamp controller receives a parking lamp extinguishing signal, controlling to extinguish the parking lamp and the vehicle logo.

Under the condition of meeting the relevant vehicle regulations, a lighting function for the vehicle logo in the parking scenario is provided, increasing the diversity of the vehicle logo lighting function.

[0045] Next, the technical solutions in the present application will be clearly and elaborately described in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may mean A or B. The "and / or" in the text is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two.

[0046] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as implying or suggesting relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0047] Different from adding an additional vehicle logo controller in the vehicle system in the related art to implement the control of the vehicle logo, in the vehicle system provided by the present application, the combined headlight controller is reused to implement the control of the vehicle logo, which not only reduces the cost of adding an additional controller chip, but also can meet the lighting requirements for multiple scenarios and dynamics of the vehicle logo.

[0048] Figure 1 It is a schematic architecture diagram of a vehicle system provided by an embodiment of the present application. As Figure 1 shown, the vehicle system includes a body domain controller 101, a combined headlight controller 102, a vehicle logo 103, a position light 104, and a power supply 105.

[0049] Among them, the combined headlight controller 102 accesses the body domain controller 101 through the CAN bus and completes function control and information interaction through network signals; the vehicle logo 103 accesses the combined headlight controller 102 through the first transmission line and completes function control and information interaction through signals; the position light 104 accesses the combined headlight controller 102 through the second transmission line; the power supply mode of the combined headlight controller 102 is constant power; the vehicle logo 103 controls the input of the power supply 105 through the high-side switch of the combined headlight controller 102 to achieve high-power output. Optionally, the first transmission line can also be an asynchronous transmission line.

[0050] From Figure 1 the vehicle system architecture shown, the combined headlight controller 102 can control the vehicle's power supply to the vehicle logo through the target switch, which can avoid abnormal power feeding of the power supply and cause the vehicle logo to be in an abnormal always-on state, wasting the vehicle's power supply.

[0051] Since the vehicle logo does not have an independent control module and is controlled by the combined headlight controller to be lit and extinguished, and the combined headlight controller itself is used to control the position light, the lighting and extinguishing scenarios of the vehicle logo in the embodiments of the present application are also related to the position light.

[0052] Based on the current vehicle-related regulations and requirements, as well as the installation position of the vehicle logo, the vehicle logo is generally classified into the category of position lights. That is to say, if the vehicle logo needs to be lit, it generally participates in the position light lighting function. And when participating in the position light lighting function, the installation position, shape, and brightness of the vehicle logo need to meet the relevant regulations of the position light. Considering that not all vehicle logos can meet the relevant regulations of the position light, for example, the vehicle logos of some vehicles are not symmetrical; in order to meet the control requirements of different types of vehicle logos, the embodiments of the present application provide corresponding lighting scenarios for these two types of vehicle logos to meet the needs of lighting vehicle logos of different vehicles.

[0053] First, for the case where the vehicle logo meets the relevant regulations of the position light, that is, the vehicle logo also belongs to a type of position light and can participate in the position light function. Figure 2 It is a schematic flowchart of a vehicle logo control method provided by an embodiment of the present application. It should be understood that this method can be executed by Figure 1 the combined headlight controller in; or, this method can also be applied to a vehicle with a Figure 1 vehicle system shown.

[0054] Exemplarily, as Figure 2 shown, the method 200 includes:

[0055] Step 201, if the vehicle logo meets the preset requirements of the position light, when the combined headlight controller receives the position light lighting signal, control to light the position light and the vehicle logo.

[0056] Among them, the vehicle logo meeting the preset requirements of the position lamp indicates that the vehicle logo meets the relevant regulatory requirements of the position lamp. For example, it meets the brightness requirements, installation position requirements, shape requirements, etc. of the position lamp; when the vehicle logo meets the preset requirements of the position lamp, the vehicle logo belongs to a type of position lamp and participates in the position lamp function.

[0057] When the vehicle logo meets the preset requirements of the position lamp, since the vehicle logo also belongs to a type of position lamp, the vehicle logo needs to be lit while the position lamp is lit. The lighting process of the vehicle logo is as follows: after receiving the position lamp lighting request, the body domain controller can send a position lamp lighting signal to the combined headlamp controller. After receiving the position lamp lighting signal, the combined headlamp controller controls the lighting of the position lamp and also controls the lighting of the vehicle logo while controlling the lighting of the position lamp. That is, the vehicle logo is lit along with the lighting of the position lamp. After the vehicle logo is lit, it functions together with the position lamp to indicate the position of the vehicle.

[0058] Exemplarily, when the combined headlamp controller receives the position lighting signal LFPosnLmpWorkCmd / RFPosnLmpWorkCmd = 1 (On) sent by the body domain controller through CAN, the combined headlamp controller controls the lighting of the position lamp and at the same time drives the vehicle logo position function, that is, lights the vehicle logo; after controlling the lighting of the position lamp and the vehicle logo, the combined headlamp controller feeds back the position lamp lighting status LFPosnLmpSts_HCM / RFPosnLmpSts_HCM = 1 (On) to the body domain controller (CEM). Among them, the position lamp lighting status indicates that both the position lamp and the vehicle logo are lit.

[0059] Step 202, when the combined headlamp controller receives the position lamp extinguishing signal, control the extinguishing of the position lamp and the vehicle logo.

[0060] Similar to the lighting process of the vehicle logo, since the vehicle logo also belongs to a part of the position lamp and participates in the position lamp function, the vehicle logo needs to be controlled to extinguish while the position lamp is extinguished. The extinguishing process of the vehicle logo is as follows: after receiving the position lamp extinguishing request, the body domain controller can send a position lamp extinguishing signal to the combined headlamp controller. After receiving the position lamp extinguishing signal, the combined headlamp controller controls the extinguishing of the position lamp and also controls the extinguishing of the vehicle logo while controlling the extinguishing of the position lamp. That is, the vehicle logo is extinguished along with the extinguishing of the position lamp. After the position lamp is extinguished, in accordance with the vehicle regulations, it is not allowed to light the vehicle logo alone.

[0061] Exemplarily, when the combined headlight controller receives the position extinguishing signal LFPosnLmpWorkCmd / RFPosnLmpWorkCmd = 0 (Off) sent by the body domain controller via CAN, it controls the position light to extinguish, and at the same time turns off the logo position function, that is, controls the logo to extinguish; at the same time, the combined headlight controller feeds back the position light extinguishing status LFPosnLmpSts_HCM / RFPosnLmpWorkCmd = 0 (Off) to the body domain controller. Among them, the position light extinguishing status indicates that both the position light and the logo are extinguished.

[0062] In this embodiment, a control method for the logo is proposed: by connecting the logo to the combined headlight controller, the original combined headlight controller in the vehicle is reused to achieve dynamic control of the logo; in addition, considering that the logo lighting needs to meet specific regulatory requirements, different lighting scenarios are provided for the logo according to whether the logo meets the preset requirements of the position light: when the logo meets the preset requirements of the position light, the position light and the logo can be controlled to light up through the position light lighting signal, so that the logo participates in the position light function and increases the diversity of the logo lighting function.

[0063] When the logo meets the relevant regulatory requirements of the position light, in addition to being able to light up when the position light lights up and having the position indication function, the logo can also participate in the light language display function of the position light, that is, display the relevant target animation together with the position light.

[0064] Figure 3 It is a schematic flowchart of another logo control method provided by the embodiments of the present application. It should be understood that this method can be executed by the Figure 1 combined headlight controller in; or, this method can also be applied to a vehicle equipped with the Figure 1 vehicle system shown.

[0065] Exemplarily, as Figure 3 shown, this method 300 includes:

[0066] Step 301, if the logo meets the preset requirements of the position light, when the combined headlight controller receives the target light language signal, control the position light and the logo to jointly display the target animation, and the target light language signal includes at least an unlocking light language signal or a locking light language signal.

[0067] When the vehicle logo meets the relevant regulatory requirements of the position light, as part of the position light, the vehicle logo can also participate in the display of the light language animation while the position light shows the light language animation, so as to achieve the dynamic lighting effect of the vehicle logo. The process of the light language display corresponding to the vehicle logo is as follows: The body domain controller receives the light language display request, sends the target light language signal to the combined headlight controller. The corresponding combined headlight controller receives the target light language signal and controls the position light and the vehicle logo to jointly display the target animation indicated by the target light language signal.

[0068] Among them, the target light language signal at least includes the unlocking light language signal and the locking light language signal. Optionally, the target light language signal can also be a welcome light language signal or other light language signals.

[0069] When the target light language signal is the unlocking light language signal, the body domain controller sends the light language demand signal and the unlocking light language signal type to the combined headlight controller. The corresponding combined headlight controller, after receiving the light language demand signal, controls the position light and the vehicle logo to display the target animation according to the target animation indicated by the unlocking light language signal type.

[0070] Exemplarily, the combined headlight controller receives the CAN signals AnimationReq = 1 and WelcomeAnimationType = (1 - 8) from the body domain controller. The combined headlight controller controls the position light and the vehicle logo to display the target animation process according to the animation mode given by WelcomeAnimationType; Optionally, the combined headlight controller will send LeftLightShowSts = 0x04 to the body domain controller until the animation is executed, so as to make it clear to the body domain controller that the target animation (unlocking light language animation) is being executed; When the target animation (unlocking light language animation) is executed, the combined headlight controller continuously sends LeftLightShowSts = 0x05 to the body domain controller 10 times, so that the body domain controller can be clear that the unlocking light language animation is executed. Among them, the purpose of sending multiple signals is to ensure that the signal receiver can receive the relevant signals.

[0071] When the target light language signal is the locking light language signal, the body domain controller sends the light language demand signal and the locking light language signal type to the combined headlight controller. The corresponding combined headlight controller, after receiving the light language demand signal, controls the position light and the vehicle logo to display the target animation according to the target animation indicated by the locking light language signal type.

[0072] Exemplarily, when the combined headlight controller receives the CAN signals AnimationReq = 1 and GoodbyeAnimationType = (1 - 8) from the body domain controller, the combined headlight controller controls the position lights and the vehicle logo to display the animation process according to the animation mode given by GoodbyeAnimationType; optionally, the combined headlight controller will send LeftLightShowSts = 0x07 to the body domain controller until the animation is executed, so as to clarify to the body domain controller that the target animation (locking light language animation) is being executed; when the target animation (locking light language animation) is executed, the combined headlight controller will also continuously send LeftLightShowSts = 0x08 to the body domain controller 10 times, so that the body domain controller can clarify that the locking light language animation is executed. Among them, the purpose of sending the signal multiple times is to ensure that the signal receiver can receive the relevant signal.

[0073] Figure 4 is a signal schematic diagram of a target light language signal provided by an embodiment of the present application. As Figure 4 shown, after the body domain controller receives the unlocking light language display request, it will send two signals to the combined headlight controller, one signal is AnimationReq = 1, and one signal is WelcomeAnimationType = (1 - 8). The value of WelcomeAnimationType can be any one of 1 - 8, and each value represents a different unlocking light language signal type; after the body domain controller receives the locking light language display request, it will send two signals to the combined headlight controller, one signal is AnimationReq = 1, and one signal is GoodbyeAnimationType = (1 - 8). The value of GoodbyeAnimationType can be any one of 1 - 8, and each value represents a different locking light language signal type.

[0074] Step 302, when the combined headlight controller receives the light language stop signal, control the position lights and the vehicle logo to stop displaying the target animation.

[0075] Similar to the vehicle logo being lit when the position lights are lit and extinguished when the position lights are extinguished, when displaying the light language, the vehicle logo participates in the light language animation of the position lights together with the position lights. When it is necessary to stop displaying the light language animation, the vehicle logo also needs to stop displaying the light language animation together with the position lights. Correspondingly, during the process of the vehicle logo and the combined headlight controller displaying the target animation, if the combined headlight controller receives the light language stop signal, it will control the position lights and the vehicle logo to stop displaying the target animation.

[0076] Exemplarily, when the combined headlight controller receives the CAN signal AnimationReq = 2 from the body domain controller, the combined headlight controller immediately controls the logo and position lights to stop the animation display; at the same time, the combined headlight controller will send LeftLightShowSts = 0x0 to the body domain controller to clearly indicate to the body domain controller that the target animation has stopped being displayed.

[0077] Figure 5 is a signal schematic diagram of a lamp language stop signal provided by an embodiment of the present application. As Figure 5 shown, after the body domain controller receives the unlock lamp language stop display request, it will send two signals to the combined headlight controller, one signal is AnimationReq = 2, and one signal is WelcomeAnimationType = 0; after the body domain controller receives the lock lamp language stop display request, it will send two signals to the combined headlight controller, one signal is AnimationReq = 2, and one signal is GoodbyeAnimationType = 0.

[0078] Step 303, when the position lights and the logo are jointly displaying the target animation, detect the component status of each light-emitting component participating in the target animation display, and the component status includes a fault status or a normal status.

[0079] The reason why the position lights and the logo can emit light is that they have several light-emitting components. For example, several LED lights are controlled to be turned on and off to achieve the lighting and extinguishing of the logo and position lights, and to achieve the dynamic lighting effect of the logo and position lights. If some light-emitting components fail, or all light-emitting components fail, the target animation cannot be continued to be displayed. Therefore, when the position lights and the logo are jointly displaying the target animation, the combined headlight controller also needs to detect the component status of each light-emitting component participating in the target animation display in real time, and then determine whether to terminate the display of the target animation according to the component status.

[0080] Among them, the method of judging the component status of the light-emitting component can be: there is an LED controller at each light-emitting component, which can detect the current situation of the light-emitting component in real time. When the current of the light-emitting component is abnormal, it is determined that the light-emitting component is in a fault status, and a fault status signal can be fed back to the combined headlight controller so that the combined headlight controller can clarify the component status of each light-emitting component; the component status includes a fault status or a normal status.

[0081] Step 304, when the fault ratio is greater than the ratio threshold, control the position lights and the logo to stop displaying the target animation, and the fault ratio is the ratio of the light-emitting components in the fault status among the light-emitting components.

[0082] Since the position lights and the vehicle logo contain several lighting components, if a single lighting component fails, it will not have a significant impact on the display of the target animation, and the target animation can still be continued to be displayed. Only when the failure of the lighting components affects the complete display of the target animation is it necessary to stop displaying the target animation. Correspondingly, in a possible implementation manner, a proportional threshold is set. When the combined headlight controller detects that the failure ratio of the lighting components is greater than the proportional threshold, it means that the target animation cannot be completely displayed, and it is necessary to control the position lights and the vehicle logo to stop displaying the target animation. Among them, the failure ratio is the ratio of the lighting components in the fault state to all the lighting components participating in the animation display.

[0083] Optionally, since the position lights and the vehicle logo are two independent parts, when determining whether to control the position lights and the vehicle logo to stop displaying the target animation, the first failure ratio of the position lights and the second failure ratio of the vehicle logo can also be obtained respectively. If the first failure ratio of the position lights is greater than the proportional threshold while the second failure ratio of the vehicle logo is less than the proportional threshold, the combined headlight controller only controls the position lights to stop the target animation display and retains the vehicle logo to continue displaying the target animation; if the first failure ratio of the position lights is less than the proportional threshold while the second failure ratio of the vehicle logo is greater than the proportional threshold, the combined headlight controller only controls the vehicle logo to stop displaying the target animation and retains the position lights to continue displaying the target animation; if both the first failure ratio of the position lights and the second failure ratio of the vehicle logo are greater than the proportional threshold, the combined headlight controller controls the position lights and the vehicle logo to stop displaying the target animation.

[0084] Exemplarily, when the combined headlight controller detects that all the lighting components participating in the animation display fail, the combined headlight controller controls the vehicle logo and the position lights to stop the animation display. At the same time, the combined headlight controller will send LeftLightShowSts to the body domain controller. The signal values can be as follows and are replied according to the current animation mode: 0x6: Unlock light Animation Failure; 0x9: Lock light Animation Failure.

[0085] In this embodiment, when the vehicle logo meets the preset requirements of the position lights, the vehicle logo belongs to a part of the position lights. Then, after the vehicle logo is lit with the position lights, it is also necessary to control the vehicle logo to go out with the position lights. The present application also proposes that when the combined headlight controller receives the position light extinguishing signal, it can control the position lights and the vehicle logo to go out simultaneously to enable the vehicle logo to participate in the position light function.

[0086] In addition, to achieve the dynamic lighting effect of the vehicle logo, the present application also proposes a vehicle logo participating in the position light lighting language function. That is, the combined headlight controller can, after receiving the target lighting language signal, control the position lights and the vehicle logo to jointly display the target animation indicated by the target lighting language signal to achieve the dynamic lighting effect of the vehicle logo. Similarly, after the combined headlight controller receives the lighting language stop signal, it will correspondingly control the position lights and the vehicle logo to stop displaying the target animation. In addition, both the vehicle logo and the position lights are composed of light-emitting components to achieve lighting. During the process of their displaying the target animation, considering the situation of light-emitting component failures, the combined headlight controller will, when detecting that the failure ratio is greater than the ratio threshold and affecting the display of the target animation, control the position lights and the vehicle logo to stop displaying the animation to avoid invalid animation display operations in case of failures.

[0087] The upper embodiment describes the situation where the vehicle logo meets the relevant regulatory requirements of the position lights and how to achieve the lighting of the vehicle logo in multiple scenarios. This embodiment mainly describes in which scenarios the vehicle logo can be lit when the vehicle logo does not meet the relevant regulatory requirements of the position lights. Figure 6 It is a schematic flowchart of another vehicle logo control method provided by an embodiment of the present application. It should be understood that this method can be executed by the Figure 1 combined headlight controller in; or, this method can also be applied to a vehicle equipped with the Figure 1 vehicle system shown.

[0088] Exemplarily, as Figure 6 shown, this method 600 includes:

[0089] Step 601, if the vehicle logo does not meet the preset requirements of the position lights, when the position lights are in the lit state and the combined headlight controller detects that the vehicle state meets the preset conditions, control the vehicle logo to be lit.

[0090] Among them, the vehicle logo not meeting the preset requirements of the position lights means that the vehicle logo does not meet the relevant regulatory requirements of the position lights. For example, meeting the brightness requirements, setting position requirements, shape requirements, etc. of the position lights; that is to say, the vehicle logo cannot participate in the lighting of the position lights as a part of the position lights. Then, in order to still be able to light the vehicle logo and meet the relevant vehicle regulatory requirements, in a possible implementation manner, when the vehicle logo does not meet the preset requirements of the position lights, the lighting process of the vehicle logo is as follows: If the combined headlight controller determines that the position lights are in the lit state and detects that the vehicle state meets the preset conditions, it can automatically control the vehicle logo to be lit.

[0091] That is to say, when the vehicle logo does not meet the preset requirements of the position lights, the combined headlight controller will automatically light the vehicle logo when the vehicle is in a specific state, and relevant regulations stipulate that the vehicle logo is allowed to be lit in this specific state.

[0092] Exemplarily, when the vehicle logo does not meet the preset requirements of the position lamp, the conditions that must be satisfied for the vehicle logo to be lit may include: (1) the position lamp is lit; (2) the vehicle speed is less than or equal to 3 km / h; (3) the vehicle speed is valid; (4) the vehicle gear is in the p gear. That is to say, only after simultaneously meeting the above 4 conditions, the combined headlamp controller will control the vehicle logo to be lit.

[0093] Step 601 may further include step 601A and step 601B.

[0094] Step 601A, if the vehicle logo does not meet the preset requirements of the position lamp, when the position lamp is in the lit state, obtain the vehicle speed, vehicle gear, and vehicle speed attribute of the vehicle, and the vehicle speed attribute is used to indicate whether the vehicle speed is valid.

[0095] After the combined headlamp controller determines that the position lamp is in the lit state, it can obtain the vehicle speed, vehicle gear, and vehicle speed attribute of the vehicle to determine whether the vehicle state meets the preset conditions, and then determine whether to light the vehicle logo.

[0096] It can be seen that when the vehicle logo does not meet the preset requirements of the position lamp, the vehicle logo will not be lit with the lighting of the position lamp, that is, the vehicle logo will not participate in the position lamp function.

[0097] Step 601B, when the combined headlamp controller detects that the vehicle speed is less than the speed threshold, the vehicle gear is in the parking gear, and the vehicle speed attribute indicates that the vehicle speed is valid, control the vehicle logo to be lit.

[0098] Based on the above vehicle logo lighting conditions, after the combined headlamp controller detects that the position lamp is lit, the vehicle speed is less than the speed threshold, the vehicle gear is in the parking gear, and the vehicle speed attribute indicates that the vehicle speed is valid, it can control the vehicle logo to be lit. Among them, the speed threshold can be 3 km / h, and the vehicle speed is less than the speed threshold, indicating that the vehicle is in a stationary state. At this time, the vehicle logo participates in the parking lighting function.

[0099] Exemplarily, when the combined headlamp controller receives the position lamp on signal LFPosnLmpWorkCmd or LRPosnLmpWorkCmd = 0x1 (on), the vehicle speed VehSpd ≤ 3 (3 kph), VehSpdVld = 0x1 (indicating that the vehicle speed is valid), and the gear TGS_LEVER = 0x0 (P gear), that is, control the vehicle logo to be lit.

[0100] Contrary to the vehicle logo lighting process, if any of the above four conditions is not met, the combined headlamp controller needs to control the vehicle logo to go out so that the lighting of the vehicle logo complies with the relevant vehicle regulations.

[0101] Step 602, when the vehicle logo is in the lit state and the combined headlight controller detects that the position light is off, control the vehicle logo to turn off.

[0102] Optionally, after the vehicle logo is in the lit state, if the combined headlight controller detects that the position light is off, that is, it does not meet the condition of the position light being lit in the vehicle logo parking lit condition, the combined headlight controller automatically controls the vehicle logo to turn off.

[0103] Step 603, when the vehicle logo is in the lit state and the combined headlight controller detects that the vehicle speed is greater than the speed threshold, control the vehicle logo to turn off.

[0104] Optionally, after the vehicle logo is in the lit state, if the combined headlight controller detects that the vehicle speed is greater than the speed threshold, that is, it does not meet the condition of the vehicle being stationary in the vehicle logo parking lit condition, the combined headlight controller automatically controls the vehicle logo to turn off.

[0105] Step 604, when the vehicle logo is in the lit state and the combined headlight controller detects that the vehicle gear is not in the parking gear, control the vehicle logo to turn off.

[0106] Optionally, after the vehicle logo is in the lit state, if the combined headlight controller detects that the vehicle gear is not in the parking gear, that is, it does not meet the condition of parking in the vehicle logo parking lit condition, the combined headlight controller automatically controls the vehicle logo to turn off.

[0107] Step 605, when the vehicle logo is in the lit state and the combined headlight controller detects that the vehicle speed attribute indicates that the vehicle speed is invalid, control the vehicle logo to turn off.

[0108] Optionally, after the vehicle logo is in the lit state, if the combined headlight controller detects that the vehicle speed attribute indicates that the vehicle speed is invalid, that is, it does not meet the condition of the vehicle speed being valid in the vehicle logo parking lit condition, the combined headlight controller automatically controls the vehicle logo to turn off.

[0109] It should be noted that the above only describes the extinguishing scenarios of the vehicle logo taking the non - satisfaction of a single condition as an example. In other possible implementation manners, when the combined headlight controller simultaneously detects that any two or more conditions for the vehicle logo parking lit condition are not met, the vehicle logo will be controlled to turn off.

[0110] In this embodiment, a control method for the vehicle logo is proposed: by connecting the vehicle logo to the combined headlight controller to reuse the original combined headlight controller in the vehicle, dynamic control of the vehicle logo is achieved; in addition, considering that the lighting of the vehicle logo needs to meet specific regulatory requirements, different lighting scenarios are provided for the vehicle logo according to whether the vehicle logo meets the preset requirements of the position light. When the vehicle logo does not meet the preset requirements of the position light, if the position light is lit, after the combined headlight controller determines that other vehicle states meet the preset conditions, the vehicle logo is controlled to be lit, so that the vehicle logo is provided with a lighting function under the condition of meeting the regulatory requirements, increasing the diversity of the vehicle logo lighting function.

[0111] In addition, considering that the vehicle logo cannot participate in the position light function when the vehicle logo does not meet the preset requirements of the position light, in order to provide a lighting scenario for the vehicle logo under the condition of meeting the regulatory requirements, this application also proposes that when the position light is lit, the vehicle speed is valid, the vehicle speed is less than the speed threshold (stationary state), and the parking gear is engaged, the vehicle logo is automatically controlled to be lit, so that the vehicle logo participates in the parking lighting function, and the vehicle logo is lit in the parking scenario under the condition of meeting the regulatory requirements; in addition, if the combined headlight controller determines that any of the position light, vehicle speed, vehicle speed attribute, and gear does not meet the requirements, the vehicle logo needs to be controlled to be extinguished in a timely manner.

[0112] In other possible implementation manners, if the vehicle is equipped with a parking light, the vehicle logo can be configured with a parking lighting function, that is, it can be lit along with the lighting of the parking light. Correspondingly, when the vehicle is equipped with a parking light, regardless of whether the vehicle logo meets the preset requirements of the position light, when the combined headlight controller receives the parking light lighting signal, the parking light and the vehicle logo can be controlled to be lit, so that the vehicle logo participates in the parking lighting function; similarly, when the combined headlight controller receives the parking light extinguishing signal, the parking light and the vehicle logo are controlled to be extinguished.

[0113] In the embodiment of this application, a vehicle logo parking lighting function is also proposed, that is, when the vehicle is equipped with a parking light, the combined headlight controller can control the vehicle logo to be lit after receiving the parking light lighting signal and control the vehicle logo to be extinguished after receiving the parking light extinguishing signal. Under the condition of meeting the relevant vehicle regulations, a lighting function for the vehicle logo in the parking scenario is provided, increasing the diversity of the vehicle logo lighting function.
