Detailed Description
In the present disclosure, unless otherwise specified, the use of the terms "first", "second", etc. to describe various elements is not intended to limit the positional relationship, the timing relationship, or the importance relationship of the elements, and such terms are used only to distinguish one element from another. In some examples, a first element and a second element may refer to the same instance of the element, and in some cases, based on the context, they may also refer to different instances.
The terminology used in the description of the various described examples in this disclosure is for the purpose of describing particular examples only and is not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the elements may be one or more. As used herein, the term "plurality" means two or more, and the term "based on" should be interpreted as "based, at least in part, on". Further, the terms "and/or" and "… …" encompass any and all possible combinations of the listed items.
In scenarios such as for level L3 (which may enable a driver not in the loop monitoring driving environment within range of the operational design domain ODD) and above autopilot systems (e.g., level L4 and L5 autopilot systems, which may enable autopilot and redundant backup capabilities where the driver is not in the loop situation at all), their capabilities need to cover low light (e.g., nighttime) autopilot scenarios. Whereas, for existing autopilot design solutions, the vehicle surroundings (e.g., lane lines, etc.) are typically output using visual sensors (e.g., cameras) and solutions for high-definition maps or lidar. The vision sensor is very dependent on the illumination intensity, and during night driving, if the illumination is lost, the lane line data can be acquired only by means of a high-definition map or a laser radar so as to keep the vehicle running normally (for example, the vehicle continues to run in transverse centering). As is known to all, a high-definition map is limited by positioning precision and map updating, the accuracy of lane line data in all scenes cannot be guaranteed, and a laser radar is greatly interfered by environmental factors of a fog lamp. Therefore, if light loss occurs during driving of the autonomous vehicle, it may cause the vehicle to perceive the surrounding environment inaccurately, thereby causing abnormal driving of the autonomous vehicle to violate a safe driving target, for example, a lateral control error.
In autonomous driving, the safety level of lateral control of the vehicle is the highest level (ASIL D). The corresponding safety objective is to avoid excessive lateral control, insufficient lateral control, loss of lateral control, opposite lateral control direction, unintended lateral control, etc. One of the major causes of errors in lateral control of autonomous vehicles is the unexpected loss or error of lane markings due to loss of ambient light. Aiming at the safety target, according to a reasonable safety level decomposition rule, the safety level of the light system is not lower than ASIL B, and meanwhile, the redundant design of the light system is required to be provided to avoid sudden loss of headlamp light in the automatic driving process of the vehicle.
In the related art, the redundancy design scheme of the lighting system includes the following three types: a redundancy scheme that the left front headlamp and the right front headlamp are separately designed; a redundancy scheme of a matrix lamp group design; the left front headlight and the right front headlight are respectively designed with independent redundancy schemes of a backup lamp group and a lamp control module (comprising a left headlight control module and a right headlight control module). However, the redundancy scheme of the separate design of the left-front and right-front headlamps has common cause failures between the lamp, the drive relay, and the lamp control module (e.g., a complete failure of the redundancy scheme in the case of a failure of the lamp control module), and furthermore, even if the brightness of the front road lighting is not sufficient in the case of the remaining one headlamp, an inaccuracy of the lane line detection by the camera may result. The lamp control module of the redundancy scheme of the matrix lamp group design often cannot diagnose each failure mode on each LED in the lamp group, so that the situation that more LEDs fail and the lamp control module cannot know the failure may occur, and the actual redundant effect of light is affected. The redundancy scheme that the left front headlamp and the right front headlamp are respectively provided with the independent backup lamp group and the lamp control module is complex in design, high in cost and large in hardware component waste.
In view of this, the present disclosure provides a vehicle light control redundancy design method and system that meets functional safety requirements for autonomous driving at L3 and above. The redundancy scheme is designed to be unified for the left front headlamp and the right front headlamp (namely, the redundancy standby scheme for controlling the left headlamp control module, the right front headlamp control module and the front grille lamp control module is arranged by the two regional control modules), and the redundancy scheme for controlling the left headlamp and/or the right front headlamp is adopted by the front grille lamp, so that common cause failure between the redundancy schemes can be avoided, the redundancy standby scheme which is independent of each other of the lighting system can be simply and reliably realized, and the safety and the reliability of the lighting system can be improved. Therefore, the condition that the output of the related sensor is inaccurate due to sudden loss of light in the running process of the vehicle can be avoided, and the safety and the reliability of vehicle driving are ensured.
Exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram illustrating an example system 100 in which various methods described herein may be implemented, according to an example embodiment.
Referring to FIG. 1, the system 100 includes an in-vehicle system 110, a server 120, and a network 130 communicatively coupling the in-vehicle system 110 and the server 120.
In-vehicle system 110 includes a display 114 and an Application (APP) 112 that may be displayed via display 114. The application 112 may be an application installed by default or downloaded and installed by the user 102 for the in-vehicle system 110, or an applet that is a lightweight application. In the case where the application 112 is an applet, the user 102 may run the application 112 directly on the in-vehicle system 110 without installing the application 112 by searching the application 112 in a host application (e.g., by the name of the application 112, etc.) or by scanning a graphic code (e.g., a barcode, a two-dimensional code, etc.) of the application 112, etc. In some embodiments, the in-vehicle system 110 may include one or more processors and one or more memories (not shown), and the in-vehicle system 110 is implemented as an in-vehicle computer. In some embodiments, in-vehicle system 110 may include more or fewer display screens 114 (e.g., not including display screens 114), and/or one or more speakers or other human interaction devices. In some embodiments, the in-vehicle system 110 may not be in communication with the server 120.
The network 130 allows wireless communication and information exchange between vehicles-X ("X" means vehicle, road, pedestrian, or internet, etc.) according to agreed communication protocols and data interaction standards. Examples of network 130 include a Local Area Network (LAN), a Wide Area Network (WAN), a Personal Area Network (PAN), and/or a combination of communication networks such as the Internet. The network 130 may be a wired or wireless network. In one example, the network 130 may be an in-vehicle network, an inter-vehicle network, and/or an in-vehicle mobile internet network.
Fig. 2a to 2c are schematic views of a light system 200 for a vehicle 2000, according to some exemplary embodiments; fig. 3 is a schematic diagram illustrating the structure of the light system 200 in fig. 2 a. As shown in fig. 2 a-2 c, the vehicle 2000 may include a light system 200. As shown in fig. 2a to 2c, the light system 200 may include: two headlights 210, 220 (e.g., left headlight 210 and right headlight 220), a front grille light 230, and a first zone control module 251 and a second zone control module 252. The two headlights each have a headlight control module (e.g., left headlight control module 241, right front headlight control module 242) configured to control the turning on and off of the corresponding headlight. The front grille lamp 230 is configured to be capable of being used as a replacement light source and/or a supplemental light source for at least one of the two headlights, the front grille lamp 230 having a front grille lamp control module 243 configured to control turning on and off of the front grille lamp. First zone control module 251 and second zone control module 252 are in communication with the headlight control modules of the two headlights and front grille light control module 243, respectively, and are configured to be able to control the headlight control modules of the two headlights and front grille light control module 243. In the normal operating state, the respective headlamp control modules of the two headlamps are controlled by the first zone control module 251 or by the first zone control module 251 and the second zone control module 252, respectively. When one of the first zone control module 251 and the second zone control module 252, which is activated in a normal operation state, malfunctions, the other of the first zone control module 251 and the second zone control module 252 is activated. In the example of FIG. 3, specifically, as shown in FIG. 3, left headlamp control module 241 is configured to control the turning on and off of left headlamp 210. The right headlight control module 242 is configured to control turning on and off of the right headlight 220. The front grill light control module 243 is configured to control the turning on and off of the front grill light 230. First zone control module 251 is configured to control left headlamp control module 241, right front headlamp control module 242, and front grille lamp control module 243. Second zone control module 252 is configured to control left headlamp control module 241, right front headlamp control module 242, and front grille lamp control module 243.
In the above embodiment, the first regional control module and the second regional control module can both individually control the left headlamp control module and the right headlamp control module, so that the first regional control module and the second regional control module can backup each other to control the left headlamp control module and the right headlamp control module, and a situation that a certain regional control module or a control module connected with the regional control module or a communication link fails is met, and another regional control module is adopted to turn on a headlamp. In addition, the first area control module and the second area control module can also control the front grille lamp according to the requirement, so that the redundancy capability after a single-point failure (one headlamp is turned off) or a double-point failure (two headlamps are turned off) occurs in the lighting system is realized, and the common cause failure caused by the faults of the left headlamp control module and the right headlamp control module is avoided. Therefore, the independent redundant backup scheme of the lighting system can be simply and reliably realized to increase the safety and reliability of the lighting system, so that the condition that the output of a related sensor is inaccurate due to sudden loss of the light in the running process of the vehicle is avoided, and the safety and reliability of the driving of the vehicle are ensured.
In some embodiments, the front grille lamp is configured such that it can be used as an alternative light source and/or a supplementary light source for at least one of the left headlamp and the right headlamp, which may be achieved by configuring the luminous intensity, the illuminance distance, and the like of the front grille lamp. In the case where the front grille lamp 230 can be used as a substitute lamp light for the left headlamp 210 and/or the right headlamp 220, parameters such as the luminous intensity, the illuminance distance (i.e., the throw distance), and the like of the front grille lamp may be set to be equal to or close to the parameters such as the luminous intensity, the illuminance distance, and the like of the left headlamp and/or the right headlamp so as to satisfy the lighting standard of the headlamps of the vehicle. In some examples, to meet the requirement of automatic driving of the vehicle, the illumination distance of the front grille lamp can also be set according to the automatic driving level. For example, when the automatic driving level of the vehicle is the L3 level, the illumination distance of the front grille lamp may be set to 30m or more, or other values as necessary. For example, when the automatic driving level of the vehicle is the level L4, the illumination distance of the front grille lamp may be set to 60m or more, or may be set to another value as necessary. For example, when the automatic driving level of the vehicle is the level L5, the illumination distance of the front grille lamp may be set to 80m or more, or may be set to another value as necessary. In the case where the front grille lamp 230 is used as a supplementary light source for the left headlamp 210 and/or the right headlamp 220, the illuminance distance and the luminous intensity of the front grille lamp may be set according to the above-described embodiment, or may be set to other values as necessary to supplement the left headlamp or the right headlamp.
Additionally or alternatively, the front grille lamp is configured such that it can be used as a replacement light source and/or a supplementary light source for at least one of the left headlamp and the right headlamp, and may also be realized by configuring the shape and color of light emitted by the front grille lamp, and the like. The front grille lamp 230 may be configured to be capable of projecting a plurality of independent light beams. In particular, the portion of the front grille lamp 230 that is adjacent to each of the two headlights can project at least one independent light beam. For example, as shown in fig. 2a to 2c, front grille lamp 230 may include a portion 231 located close to left headlamp 210 and a portion 232 located close to right headlamp 220. The portion 231 of the grille lamp adjacent to the left headlight can project at least one individual light beam, and the portion 232 of the grille lamp adjacent to the right headlight can project at least one individual light beam. In some examples, the front grille lamp 230 may be an LED lamp or the like. The shape of the light beam projected by the front grille lamp 230 may be any shape such as a circle, a square, a diamond, etc. In addition, the light beam projected by the front grille lamp 230 may be incandescent light or other colors of light that can meet certain illumination distance requirements.
In some embodiments, the front grille lamp control module 243 may include a front grille lamp control unit (e.g., a micro control unit MCU or the like), a driver and a lamp actuator, and the like. The portion 231 near the left headlamp 210 and the portion 232 near the right headlamp 220 may be controlled individually or simultaneously by the front grille lamp control module 243 as needed.
In some embodiments, at least one of left headlamp control module 241 and right headlamp control module 242 may include a headlamp control unit (e.g., a micro control unit MCU, etc.), a drive and lamp actuator, etc., such that turning on and off of the left headlamp and right headlamp, respectively, may be controlled/driven.
In some embodiments, as shown in fig. 3, the light system 200 may further include: a first communication link L1, a second communication link L2, a third communication link L3, a fourth communication link L4, a fifth communication link L5, and a sixth communication link L6. First communication link L1 is used to transmit signals between first zone control module 251 and left headlamp control module 241 and between left headlamp control module 241 and left headlamp 210. The second communication link L2 is used to transmit signals between the first zone control module 251 and the right headlight control module 242 and between the right headlight control module 242 and the right headlight 220. Third communication link L3 is used to transmit signals between second zone control module 252 and left headlamp control module 241 and between left headlamp control module 241 and left headlamp 210. The fourth communication link L4 is used to transmit signals between the second zone control module 252 and the right headlight control module 242 and between the right headlight control module 242 and the right headlight 220. The fifth communication link L5 is used to transmit signals between the first zone control module 251 and the front grill lamp control module 243 and between the front grill lamp control module 243 and the front grill lamp 230. The sixth communication link L6 is used to transmit signals between the second zone control module 252 and the front grille lamp control module 243 and between the front grille lamp control module 243 and the front grille lamp 230. The above-described embodiments may implement a redundant backup scheme for controlling the communication links of the left headlamp, the right headlamp and the front grille lamp. For example, the first communication link and the third communication link for controlling the left headlamp may serve as redundant backup communication links for each other. For another example, the second communication link and the fourth communication link for controlling the right front headlamp may serve as communication links for redundant backup of each other. Also for example, the fifth communication link and the sixth communication link for controlling the front grille lamp may serve as communication links redundantly backup for each other, and may further serve as communication links redundantly backup for at least one of the first communication link, the second communication link, the third communication link, and the fourth communication link. Thus, in the event of a failure of one or more of the communication links, the backup communication link may be enabled to turn on the headlights and/or grille lights to ensure proper vehicle operation.
In some embodiments, the light system 200 may also include a first power source 261 and a second power source 262. The first power source 261 is used to supply power to the first zone control module 251, and the second power source 262 is used to supply power to the second zone control module 252. Therefore, a scheme of mutual redundancy backup between the first power supply and the second power supply can be realized. For example, in the case of a failure of the first power supply, the second power supply may be used to supply power to the second zone control module to turn on the left headlamp or the right headlamp again. Alternatively, the first zone control module may also be powered using the second power source, or by a mix of the first and second power sources. The second area control module can also be powered by the first power supply or by a mixture of the first power supply and the second power supply. The redundancy of the system can be further increased by adopting a mode of hybrid power supply of the first power supply and the second power supply. For example, when a first zone control module is powered by a mixture of a first power source and a second power source, the second power source may be used to power the first zone control module without switching zone control modules in the event of a failure of the first power source. In some examples, the power provided by the first power source and the second power source may be the same or different.
In some embodiments, the first zone control module 251 may be used to power the communication links used by the first zone control module (e.g., the first communication link L1, the second communication link L2, and the fifth communication link L5). Accordingly, the second zone control module 252 can be used to power the communication links (e.g., the third communication link L3, the fourth communication link L4, and the sixth communication link L6) to which the second zone control module is connected.
In some embodiments, each of left headlamp control module 241, right front headlamp control module 242, and front grille lamp control module 243 is selectively powered by one of first power source 261 and second power source 262. That is, each of the left headlamp control module, the right headlamp control module, and the front grille lamp control module may be powered by a combination of the first power source and the second power source. Because no matter which communication link controls left headlamp in lighting system 200, right front headlamp, the front grille lamp, all need to pass through left headlamp control module respectively, right front headlamp control module and front grille lamp control module, consequently adopt first power and second power to left headlamp control module, right front headlamp control module and front grille lamp control module carry out hybrid power supply, can be under one of them power failure's the condition, still can use another power to left headlamp control module, right front headlamp control module and front grille lamp control module power supply, in order to ensure these lamp control module's normal operating.
In some other embodiments, each of left headlamp control module 241, right front headlamp control module 242, and front grille lamp control module 243 may be selectively powered by one of first zone control module 251 and second zone control module 252. That is, each of the left headlamp control module, the right headlamp control module, and the front grille lamp control module may be powered by a mix of the first zone control module and the second zone control module. Thus, the normal operation of these control modules can be ensured.
Fig. 4 is a flowchart illustrating a control method 400 for a light system (e.g., light system 200 in fig. 2 a-2 c and 3) of a vehicle (e.g., vehicle 2000 in fig. 2 a-2 c), according to some example embodiments. The control method 400 may be performed on the vehicle side, in particular, for example, at a control device in the vehicle, i.e. the subject of execution of the control method 400 is the control device in the vehicle. The individual steps of the control method 400 will be described in detail below in connection with fig. 2a to 2c, fig. 3 and fig. 4.
As shown in fig. 4, the control method 400 may include: step 410, determining whether to turn on at least one of the two headlights; step 420, in response to determining to turn on at least one headlamp, causing the lighting system 200 to perform a first operation to turn on the first headlamp; step 430, in response to the at least one headlamp not being turned on, obtains a fault status of the lighting system 200, and based on the fault status, causes the lighting system 200 to perform a second operation to turn on the front grille lamp 230 and/or turn on the at least one headlamp again.
The at least one headlamp may be a left headlamp or a right headlamp. In the example of fig. 2a to 2c, it is assumed that the at least one headlight is a left headlight 210. At this time, the control device in vehicle 2000 causes light system 200 to perform the first operation to turn on left headlamp 210. If left headlight 210 in light system 200 is not switched on, a corresponding standby operation is carried out by light system 200, based on the fault state of the light system, in order to switch front grille lamp 230 on (as an alternative light source, as shown in fig. 2 c), or to switch left headlight 210 on again (light state as shown in fig. 2 a), or to switch front grille lamp 230 on (as a supplementary light source) and switch left headlight 210 on again (as shown in fig. 2 b). The case of at least one headlight with a right headlight is the same as the case of a left headlight and will not be described in detail here for the sake of brevity.
Furthermore, the at least one headlight may also be referred to as both the left headlight and the right headlight. At this time, the non-activation of the at least one headlamp in step 430 may include non-activation of the left headlamp, non-activation of the right headlamp, non-activation of both the left headlamp and the right headlamp. Accordingly, the switching on of at least one headlight may mean switching on of a previously unsuccessfully switched on headlight of both the left headlight and the right headlight. In the example of fig. 2a to 2c, it is assumed that at least one headlight refers to both left headlight 210 and right headlight 220. At this time, the control device in the vehicle 2000 causes the light system 200 to perform the first operation to turn on the left headlamp 210 and the right headlamp 220. If at least one of the headlights is not switched on, i.e. left headlight 210 is not switched on, then, depending on the fault state of the lighting system, the lighting system is operated to perform a corresponding backup operation, so that grille light 230 is switched on (as shown in fig. 2 c), or at least one of the headlights is switched on again, i.e. left headlight 210 is switched on again (as shown in fig. 2 a), or grille light 230 is switched on and at least one of the headlights is switched on again, i.e. left headlight 210 is switched on again (as shown in fig. 2 b).
Wherein, the fault state of lighting system can include: at least one of a failure of the first regional control module or the second regional control module, a failure of the first power supply or the second power supply, a failure of the first communication link and/or the second communication link, a failure of the left headlamp control module and/or the right headlamp control module, and the like. The vehicle control device may detect a fault in the lighting system itself, or determine a fault state of the lighting system based on a fault report sent by the lighting system.
The above-described embodiment makes it possible to enable a backup operation in order to switch on the headlights again or to switch on the grille lights as replacement lights or as supplementary lights in the event that the lighting system fails to switch on the left headlight and/or the right headlight using the first operation. Therefore, the safety and reliability of the light system can be improved, so that the condition that the output of a related sensor is inaccurate due to sudden loss of light in the running process of the vehicle is avoided, and the safety and reliability of vehicle driving are ensured.
In some embodiments, a light operation command (which may include a light-on command and a light-off command) that indicates turning on at least one headlamp may be generated by a headlamp turn-on button that is pressed or touched by a user. Generating a light operation instruction indicating turning on of at least one headlamp in response to sensing that a user in the vehicle presses or touches a headlamp turn-on button in the vehicle, and transmitting the light operation instruction to the vehicle control device; or, the headlight function is turned on through an intelligent end device (such as a mobile phone, a smart watch and the like) in communication connection with the vehicle end to generate a light operation instruction. At this time, in step 410, it may be determined whether to turn on at least one headlamp based on whether the light operation command is received. Alternatively, it may also be determined whether to turn on at least one headlight depending on the illumination state of the surroundings as sensed by the vehicle sensors.
In some embodiments, in step 420, the vehicle control device may cause the light system 200 to perform a first operation by sending a light operation request to the light system to turn on at least one headlamp. The light operation request may only include at least one headlamp turn-on command. In this case, the specific action of the first operation is determined by the lighting system itself, so that at least one headlight is switched on. Alternatively, the light-on request may include at least one headlamp-on instruction and an instruction regarding the first operation to cause the lighting system to perform the first operation.
In some embodiments, step 430 may include: in response to the at least one headlight not being switched on, the lighting system is caused to perform a second operation by sending an instruction to the lighting system relating to the second operation, so that the grille lamp is switched on and/or the at least one headlight is switched on again. Alternatively, the light system may determine the specific action of the second operation by itself, and issue a request for performing the second operation to the vehicle control device. At this time, step 430 may include: in response to the at least one headlamp not being on and receiving the request to perform the second operation, the lighting system is caused to perform the second operation by sending an indication of consent to the lighting system to turn on the front grille lamp and/or turn on the at least one headlamp again.
In some embodiments, control method 400 may further include, in response to determining to turn on at least one headlamp, causing lighting system 200 to perform a third operation to turn on portions of front grille lamp 230 that are proximate to the at least one headlamp. In this way, the front grille lamp can be used as a supplementary light source for at least one headlight, so that the lighting effect of the headlight is improved, and the vehicle can run more safely and reliably.
In some embodiments, the first operation may be an action performed for turning on the left headlamp and/or the right headlamp in case the light system is not faulty. The third operation may be an action performed to turn on the front grille lamp in the case where the light system is not faulty. In some examples, the first operation and the third operation may be as shown in table 1 below. Table 1 shows the components of the lighting system 200 involved in performing control actions for turning on the headlights and grille lights in the normal state.
Table 1 control actions of the lighting system 200 in a normal state
As shown in table 1, in the case where the at least one headlamp is a left headlamp, the first operation may include an act of causing the first zone control module to control the left headlamp control module using the first communication link. In the case where the at least one headlamp is a right headlamp, the first operation may include an act of causing the first zone control module to control the right headlamp control module using the second communication link. In the case where the at least one headlamp is both a left headlamp and a right headlamp, the first operation may include an act of causing the first zone control module to control the left headlamp control module using the first communication link and an act of causing the first zone control module to control the right headlamp control module using the second communication link. The third operation may include an act of causing the first zone control module to control the front grille lamp control module using a fifth communication link. It should be understood here that since in the light system 200, a first zone control module is powered by a first power source, while a second zone control module is powered by a second power source. Thus, the first and third operations may also include the act of powering the first zone control module by the first power source.
In some other examples, the first operation and the third operation may be as shown in table 2 below. Table 2 shows the components of the lighting system 200 involved in performing the control actions for turning on the headlights and the grille lights in the normal state.
Table 2 control actions of the lighting system 200 in a normal state
As shown in table 2, in the case where at least one headlamp is a left headlamp, the first operation may include an act of causing the first zone control module to control the left headlamp control module using the first communication link. In the case where the at least one headlamp is a right headlamp, the first operation may include an act of causing the second zone control module to control the right headlamp control module using the fourth communication link. In the case where the at least one headlamp is both a left headlamp and a right headlamp, the first operation may include an act of causing the first zone control module to control the left headlamp control module using the first communication link and an act of causing the second zone control module to control the right headlamp control module using the fourth communication link. The third operation may include an act of causing the first zone control module to control the front grille lamp control module using a fifth communication link. Further, in the lighting system 200, the first zone control module is powered by the first power source, and the second zone control module is powered by the second power source. Thus, the first operation may also include the act of powering the first zone control module by the first power source and/or the act of powering the second zone control module by the second power source. The third operation may also include an act of powering the first zone control module by the first power source.
The control actions of the light system 200 in the normal state described above are merely exemplary, the first operation may be any one or combination of the actions described above for turning on the left headlamp and/or the right headlamp, for example, the first operation may include an action of causing the second zone control module to control the left headlamp control module using the third communication link and/or an action of causing the second zone control module to control the right headlamp control module using the fourth communication link, and the disclosure is not limited thereto. Likewise, the third operation may comprise an act of causing the second zone control module to control the front grille lamp control module using a sixth communication link.
In addition, the second operation may be an alternative operation different from the first operation for turning on the left headlamp and/or the right headlamp in the event of a failure of the light system. For example, in the case where the first operation uses the control action shown in table 1, the second operation may be as shown in table 3 below. Table 3 shows the components that are involved in a second operation that can be performed by the lighting system to switch on the front grille lamp and/or to switch on at least one headlight again in different fault states, based on the control actions of the lighting system in table 1 in the normal state.
Table 3 control actions of the lighting system 200 in a fault state
As shown in table 3, for example, in the case where the fault condition includes a first power failure and the at least one headlamp is a left headlamp, the second operation may include an act of powering the second zone control module by the second power source and an act of causing the second zone control module to control the left headlamp control module via the third communication link. Alternatively or additionally, the second operations may further comprise an act of causing the second zone control module to control the front grille lamp control module via a sixth communication link. For another example, where the at least one headlamp is a left headlamp and the fault status is a failure of the first communication link, the second operation may include an act of powering the second zone control module from the second power source and an act of causing the second zone control module to control the left headlamp control module using the third communication link. Alternatively or additionally, the second operation may include an action of supplying power to the first zone control module by the first power source and an action of causing the first zone control module to control the front grille lamp control module using the fifth communication link, or an action of supplying power to the second zone control module by the second power source and an action of causing the second zone control module to control the front grille lamp control module using the sixth communication link. That is, in the case of a specific fault state, the second operation may select the operation shown in any one row or the combination of the operations shown in any two rows in table 3 above in relation to the specific fault state.
In addition, in the case where the first operation uses the control action shown in table 2, the second operation may be as shown in table 4 below. Table 4 shows the components that are involved in a second operation that can be performed by the lighting system to switch on the front grille lamp and/or to switch on at least one headlight again in different fault states, based on the control actions of the lighting system in table 2 in the normal state.
TABLE 4 control actions of the light system 400 in the Fault State
As shown in table 3, for example, in the case where the at least one headlamp is the right headlamp and the failure status includes a failure of the second power supply or the second zone control module, the second operation may include an action of supplying power to the first zone control module by the first power supply and an action of causing the first zone control module to control the right headlamp control module through the second communication link. Alternatively or additionally, the second operations may further comprise an act of causing the first zone control module to control the front grille lamp control module via a fifth communication link. For another example, in a case where the at least one headlamp is the right headlamp and the failure status is a failure of the fourth communication link, the second operation may include an action of supplying power to the first zone control module by the first power supply and an action of causing the first zone control module to control the right headlamp control module using the second communication link. Alternatively or additionally, the second operation may include an action of supplying power to the first zone control module by the first power source and an action of causing the first zone control module to control the front grille lamp control module using the fifth communication link, or an action of supplying power to the second zone control module by the second power source and an action of causing the second zone control module to control the front grille lamp control module using the sixth communication link. That is, in the case of a particular fault state, the second operation may select the operation shown in any one row or the combination of the operations shown in any two rows in table 4 above in relation to that particular fault state.
It should be understood here that the present disclosure is not limited to the above-described examples, and that a first operation for turning on at least one headlamp in the normal state and an alternative operation for turning on at least one headlamp again and/or turning on a front grille lamp in the fault state, which is different from the first operation, may be selected in the lighting system according to actual needs.
In some embodiments, the first operation includes an act of powering the first zone control module by the first power source, the fault status indicating a failure of the first power source. At this time, causing the light system to perform the second operation to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault state includes: based on the first power failure, the lighting system executes the action of supplying power to the second area control module by the second power supply so as to at least enable at least one headlamp to be turned on again. For example, taking tables 2 and 4 as an example, assuming that at least one of the headlights is left headlight 210, the first operation includes an action of supplying power to first zone control module 251 from first power supply 261. At this time, in the case where the fault state indicates that the first power supply 261 is faulty, the second operation may include an action of supplying power to the second zone control module 252 from the second power supply 262 so that the left headlamp 210 is turned on again. Additionally or alternatively, the first operation may include the acts of powering the first zone control module by a first power source and powering the second zone control module by a second power source, the fault status indicating a failure of one of the first power source and the second power source, and based on the fault status, causing the lighting system to perform the second operation to turn on the front grille lamp and/or the at least one headlamp again may include: based on one power failure in the first power supply and the second power supply, the lighting system is enabled to execute the action of supplying power to the area control module in the first area control module and the second area control module, wherein the area control module is powered by the other power supply, so that at least one headlamp is turned on again. For example, taking tables 2 and 4 above as an example, assuming that at least one of the headlights is the right headlamp 220, the first operation includes the action of powering the second zone control module 252 by the second power source 262. At this time, in the case where the fault state indicates that the second power supply 262 is faulty, the second operation may include an action of supplying power to the first zone control module 251 by the first power supply 261 to turn on the right headlamp 220 again. The above-described embodiments make it possible to use the non-defective one of the first or second power supplies to supply the zone control modules with power to turn on the respective headlights and/or grille lights in the event of a failure of the other, so as to ensure normal driving of the vehicle.
In some other embodiments, causing the lighting system to perform the second operation to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault condition may also include: and based on the first power failure, enabling the lighting system to execute the action of supplying power to the second area control module by the second power supply so as to at least enable the front grille lamp to be turned on, or based on the second power failure, enabling the lighting system to execute the action of supplying power to the first area control module by the first power supply so as to at least enable the front grille lamp to be turned on.
In some embodiments, causing the lighting system to perform the act of powering the second zone control module from the second power source based on the first power failure to turn on at least one headlamp again comprises: based on the first power failure, the lighting system is caused to execute an action of supplying power to the second area control module by the second power supply, so that the at least one headlamp is turned on again and a part of the front grille lamp close to the at least one headlamp is turned on. Further, based on a failure of one of the first and second power sources, causing the lighting system to perform the act of powering the area control module of the first and second area control modules that is powered by the other of the first and second power sources to turn on at least one headlamp again may include: based on a power failure of one of the first and second power supplies, the lighting system is caused to perform an action of supplying power from the other of the first and second power supplies to one of the first and second zone control modules that is supplied with power from the other power supply, so that the at least one headlamp is turned on again and a portion of the front grille lamp that is close to the at least one headlamp is turned on. The above-described embodiments may enable, in the event of a failure of one of the first or second power sources, the use of the other, which is not faulty, to power the zone control modules to turn on the respective headlights and grille lights, thereby further ensuring normal driving of the vehicle. In the above-described embodiment, as for the front grille lamp, only a portion of the front grille lamp near at least one headlamp is turned on, alternatively, the entire front grille lamp may be turned on, and the present disclosure is not limited thereto.
In some embodiments, the first operation includes an action of causing one of the first and second zone control modules corresponding to the at least one headlamp to control one of the at least one headlamp, the fault status indicates that the zone control module corresponding to the at least one headlamp of the first and second zone control modules is faulty, and causing the lighting system to perform the second operation to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault status may include: based on the fault of the area control module corresponding to at least one headlamp in the first area control module and the second area control module, the lighting system at least executes the action of controlling at least one headlamp by the other one of the first area control module and the second area control module so as to enable at least one headlamp to be turned on again. For example, taking tables 2 and 4 above as examples, the at least one headlamp is left headlamp 210, and the first operation includes causing first zone control module 251 to control the operation of the left headlamp using first communication link L1. At this time, in the case where the fault state indicates that the first zone control module 251 is faulty, the second operation may include at least causing the second zone control module 252 to control the operation of the left headlamp using the third communication link L3, so that the left headlamp 210 is turned on again. The above-described embodiment can ensure that, in the event of a failure of one of the first zone control module and the second zone control module, the corresponding headlamp is turned on using the other, which has no failure, thereby ensuring normal driving of the vehicle. Additionally or alternatively, the causing the lighting system to perform the second operation to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault condition may include: based on a failure of one of the first and second zone control modules corresponding to the at least one headlamp, the lighting system is caused to perform at least an action of controlling the front grille lamp control module by the other of the first and second zone control modules so that the front grille lamp (e.g., a portion of the front grille lamp that is close to the at least one headlamp, etc.) is turned on.
In some embodiments, the first operation comprises an act of causing one of the first and second area control modules corresponding to the at least one headlamp to control a headlamp control module of the at least one headlamp, the fault status indicates that the headlamp control module of the at least one headlamp is faulty, and causing the lighting system to perform the second operation to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault status comprises: based on the fault of the headlamp control module of at least one headlamp, the lighting system is enabled to execute the action of enabling the first area control module or the second area control module to control the front grille lamp control module, so that the part of the front grille lamp close to the at least one headlamp is turned on. For example, taking the above tables 2 and 4 as an example, assuming that at least one of the headlights is the right headlight 220, the first operation includes an operation of causing the second zone control module 252 to control the right headlight control module 242 using the fourth communication link L4. At this time, in the case where the failure state indicates the right front headlight control module failure 242, the second operation may include causing the first zone control module 251 to control the operation of the front grille lamp control module 243 using the fifth communication link L5 or causing the second zone control module 252 to control the operation of the front grille lamp control module 243 using the sixth communication link L6 so that the portion 232 of the front grille lamp 230 near the right front headlight 220 is turned on. The embodiment can realize that the front grille lamp is used for replacing a corresponding headlamp under the condition that the lamp control module has a fault, thereby ensuring the normal running of the vehicle. In the above-described embodiment, as for the front grille lamp, only a portion of the front grille lamp near at least one headlamp is turned on, alternatively, the entire front grille lamp may be turned on, and the present disclosure is not limited thereto.
In some embodiments, the power rating of the first power source is greater than the power rating of the second power source. At this time, causing the lighting system to perform an action of causing the first zone control module or the second zone control module to control the front grille lamp control module based on a failure of a headlamp control module (e.g., at least one of a left headlamp control module and a right headlamp control module) of the at least one headlamp to turn on a portion of the front grille lamp near the at least one headlamp includes: based on the fault of the headlamp control module of at least one headlamp, the lighting system is enabled to execute the action of enabling the first area control module to control the front grille lamp control module, so that the part of the front grille lamp close to the at least one headlamp is turned on. Therefore, the power supply with higher rated power can be selected to supply power to the connected area control module so as to control the front grille lamp to be turned on, and therefore the brightness of the front grille lamp is ensured. Alternatively, in the case where the second power source has a higher power than the first power source, the second area control module may be selected to control the front grill lamp control module.
In some embodiments, the first operation includes an act of causing the first zone control module to communicate using a communication link of the first communication link and the second communication link for controlling the at least one headlamp, the fault status indicating a communication link fault for controlling the at least one headlamp. At this time, causing the light system to perform the second operation to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault state may include: based on the communication link failure for the at least one headlamp, causing the lighting system to perform at least the act of causing the second zone control module to communicate using the communication link for the at least one headlamp of the third communication link and the fourth lane link to turn the at least one headlamp on again. For example, taking tables 2 and 4 above as an example, assuming that at least one of the headlights is left headlight 210, the first operation includes causing first zone control module 251 to control the operation of left headlight control module 241 using first communication link L1. At this time, in the case where the fault status indicates that the first communication link L1 is faulty, the second operation may include at least causing the second zone control module 252 to control the operation of the left headlamp control module 241 using the third communication link L3 to turn on the left headlamp 210 again. In some other embodiments, the first operation includes an act of causing the second zone control module to communicate using a communication link for the at least one headlamp of the third communication link and the fourth communication link, the fault status indicates a communication link fault for the at least one headlamp, and based on the fault status, causing the lighting system to perform the second operation to cause the front grille lamp to turn on and/or the at least one headlamp to turn on again includes: based on the communication link failure for the at least one headlamp, the lighting system is caused to perform at least the action of the first zone control module using the communication link for the at least one headlamp in the first communication link and the second access link to turn the at least one headlamp on again. For example, taking the above tables 2 and 4 as an example, assuming that at least one of the headlights is the right headlight 220, the first operation includes an operation of causing the second zone control module 252 to control the right headlight control module 242 using the fourth communication link L4. At this time, in the case where the fault status indicates that the fourth communication link is faulty, the second operation may include at least an operation of causing the first zone control module 251 to control the right headlamp control module 242 using the second communication link L2 so as to turn on the right headlamp 220 again. Additionally or alternatively, the causing the lighting system to perform the second operation to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault state may further include: based on a communication link failure for the at least one headlamp, causing the lighting system to perform at least an act of causing the first zone control module or the second zone control module to control the front grille lamp control module to cause the front grille lamp (e.g., a portion of the front grille lamp that is proximate to the at least one headlamp, etc.) to turn on. The above-described embodiment can ensure that the normal driving of the vehicle is ensured by turning on the corresponding headlamp using the communication link without the failure in the case of the failure of the communication link.
Fig. 5 is a flowchart illustrating a control method 500 for a standby area control module (i.e., an area control module of the first and second area control modules 251 and 252 that is used in an abnormal state) of a light system (e.g., the light system 200 of fig. 2 a-2 c and 3), according to some example embodiments. In some embodiments, the control method 500 may be performed at an area control module (e.g., the first area control module 251 and/or the second area control module 252) of a light system (e.g., the light system 200 of fig. 2 a-2 c and 3), i.e., the subject of performance of the control method 500 is the area control module of the light system.
As shown in fig. 5, the control method 500 may include: step 510, determining whether a light operation request is received, wherein the light operation request comprises a request for indicating to turn on at least one headlamp of two headlamps; and step 520, responding to the situation that at least one headlamp is not turned on, determining the fault state of the light system, and executing light turning-on operation based on the fault state so as to turn on the front grille lamp and/or turn on at least one headlamp again. The above-described embodiment makes it possible to enable a backup operation in order to switch on the headlights again or to switch on the grille lights as replacement lights or as supplementary lights in the event that the lighting system fails to switch on the left headlight and/or the right headlight using the first operation.
In the above embodiment, the light operation request may be generated by the vehicle control apparatus executing the control method 400 and transmitted to the light system 200, or alternatively, the light operation request may be generated by the user pressing or touching a headlamp on button and transmitted to the light system 200.
It should be understood that the features of the light operation request, the at least one headlamp, the fault condition, and the at least one headlamp re-activation in control method 500 described above are the same as the features of the light operation request, the at least one headlamp, the fault condition, and the at least one headlamp re-activation in control method 400, and for the sake of brevity, will not be described in detail herein.
In some examples, the backup area control module may request from the vehicle control device to re-control the at least one headlamp on based on the detected fault condition. At this time, performing a light-on operation to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault state may include: in response to receiving an approval indication transmitted by the vehicle control device, a light-on operation is performed to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault state.
In some embodiments, when the act of first turning on at least one headlamp is performed by a zone control module of an executive of control method 500, control method 500 may further include: in response to receiving the light operation request, at least one headlamp is caused to perform a turn-on action. For example, the zone control module controls a light control module for controlling at least one headlight by using a corresponding communication link, so that the headlights perform a switching-on action.
In embodiments where the specific action of the light-on operation may be self-determined by the zone control module based on the fault status, the fault status indicates a power failure for powering a main zone control module in the light system or a main zone control module fault or a communication link connected to a main zone control module fault. At this time, performing a light-on operation to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault state may include: based on the fault state, at least the respective headlamp control module of the at least one headlamp (i.e. one of the left and right headlamp control modules for the at least one headlamp) is controlled such that the at least one headlamp is switched on again. For example, in the case where the execution subject of the control method 500 is the first area control module, the main area control module refers to the second area control module. After the second zone control module executes the action of starting the at least one headlamp for the first time, the first zone control module controls at least a lamp control module for controlling the at least one headlamp based on the detected power failure of the power supply for the second zone control module or the failure of a communication link connected with the second zone control module, so that the at least one headlamp is started again. The above-described embodiments may enable performing a backup operation to ensure proper illumination of the vehicle in the event of a failure of the light system. Alternatively, performing a light-on operation to turn on the front grille lamp and/or turn on the at least one headlamp again based on the fault state may include: based on the fault condition, the front grille lamp control module is controlled to turn on the front grille lamp (e.g., a portion of the front grille lamp that is close to at least one headlamp).
