Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The control of the functions of the conventional vehicle exterior lighting system is generally realized by operating a combination switch and a remote control (T-BOX: Telematics). The combined switch is a multifunctional combined switch for controlling the lighting and light signal device and other accessories. And the vehicle-mounted T-BOX is mainly used for communicating with a background system/mobile phone APP, so that the vehicle information display and control of the mobile phone APP are realized. Different vehicle types of the structure of the combination switch have different combination forms, and the operation logics of partial functions (such as accompanying self to go home, fog light and the like) are complex, so that inconvenience is brought to users, especially novice users, in operating the light. And partial functions, such as remote control of light, can be realized only in a static state of the vehicle, and the driving requirements cannot be met. Traditional techniques are significantly less intelligent and convenient.
The method for controlling the vehicle external illuminating lamp through voice can be applied to the application environment shown in fig. 1. The voice recognition system 102 communicates with a BCM (body control module) 104 through a bus via a network, and the combination switch 106 and the external illumination lamp 108 communicate with the BCM (body control module) 104 through a hard wire. Among other things, based on embodiments of the present invention, BCM is able to handle conflicts between switching and voice input. The BCM is communicated with a voice recognition system through a bus; the combination switch is connected to the BCM through a hard wire, and the BCM drives external light to be lightened through the hard wire.
In one embodiment, as shown in fig. 2, a method for controlling an external illumination lamp of a vehicle by voice is provided, which is exemplified by applying the method to a vehicle body control module in fig. 1, and comprises the following steps:
and 202, detecting the state of a combination switch of the vehicle when a voice request instruction is received.
When the voice recognition system recognizes a request of turning on or off the external illuminating lamp by voice, a corresponding bus signal (namely, a voice request instruction) is sent to a vehicle body control module (hereinafter, referred to as BCM).
Specifically, the BCM checks the status of the combination switch after receiving the request. The combined switch is a multifunctional combined switch for controlling lighting and light signal devices and other accessories. Typically of the handlebar type, is mounted on the steering column under the steering wheel for easy handling by the driver. Generally, a combination switch is divided into two handles and one button. Further, the combination switch state refers to an ON/OFF state of each switch of the exterior illumination lamp corresponding to the vehicle in the combination switch, and may be an ON state (ON state) or an OFF state (OFF state); when the switch is in an ON state, the corresponding external illuminating lamp is lightened; when the switch is in the OFF state, the corresponding external illuminating lamp is turned OFF.
Step 204, when the detection result is that all switches of the external illuminating lamps corresponding to the vehicle in the combined switch are in a closed state, entering a voice control mode, and responding to a voice request instruction to light on or turn off the corresponding external illuminating lamps; the exterior lights include position lights, dipped headlights, high beams, front fog lights, and rear fog lights.
The BCM comprehensively judges whether to execute a voice request instruction according to the state of the combination switch and the voice request signal; specifically, when the BCM detects that any external light switch is turned on, the voice request command is not responded. Only when all the external light switches are turned off, the BCM enters a voice control mode and executes a voice request command.
For example, a voice on/off position light function can be implemented based on the present invention: the speech recognition system recognizes the on position light request and sends the request to the BCM. And the BCM checks the state of the combined switch after receiving the request, enters a voice control mode and controls the position lamp to be lightened if the combined switch is in an OFF gear (the combined switch is in the OFF gear, namely the switch corresponding to all external illuminating lamps is in the OFF gear, namely the combined switch is in the OFF state), and does not control the position lamp to be lightened if the combined switch is not in the OFF gear. Based on the same detection method, the BCM controls the turn-off of the position lamp when the position lamp is required to be turned off.
Further, the voice request instruction is an instruction transmitted by the CAN bus when the voice recognition system recognizes a request of turning on or turning off any external illuminating lamp by voice.
It should be noted that the BCM communicates with the voice recognition system through a CAN bus (Controller Area Network); when the voice recognition system recognizes a request of turning on or turning off an external illuminating lamp by voice, a bus request signal is sent to a BCM (vehicle body control module) through a CAN bus, and the BCM comprehensively judges whether to execute a voice request instruction according to the state of a combination switch and the bus request signal.
Further, the voice request instruction is a CAN bus signal of the event type message.
It should be noted that the event type message is one of the CAN bus signals, and corresponds to the periodic message. Aiming at the characteristics that the voice input CAN not be kept in the state and is finished after the voice input is finished (and the switch is in the open state after being opened), the CAN bus signal of the event type message is selected to transmit the voice request, so that the bus load rate CAN be obviously reduced.
To further illustrate a specific implementation process for detecting the status of the combination switch of the vehicle, fig. 3 is a schematic diagram illustrating a specific connection relationship between the BCM and the external lighting system; as shown in fig. 3, the step of detecting that each switch of the combination switch corresponding to the exterior illumination lamp of the vehicle is in an off state may include:
and when detecting that the connecting port corresponding to the switch is in a low level, confirming that the switch is in a closed state.
In particular, the combination switch may be hardwired directly to the port of the BCM, which when a low level is detected at the port of the BCM means that the switch is closed. Further, as shown in fig. 3, when the BCM receives an instruction of turning on the external illumination lamp by voice, it detects that all the external illumination lamp switches are in an OFF state, and outputs a high level at the driving port of the corresponding external illumination lamp to light the external illumination lamp.
In the method for controlling the vehicle external illuminating lamp by the voice, the BCM can process the conflict between the combination switch and the voice input to perform corresponding voice control, and a user only needs to speak the requirements, and the complex judgment logic is judged by the BCM. The invention is not limited to the vehicle speed state, can use voice to control external light in driving, gets rid of the dependence on the combination switch, liberates the complex logic of the user to operate the combination switch, has more convenience on the basis of meeting the intelligence and functionality, and lays a certain foundation for the realization of the unmanned technology.
In one embodiment, as shown in fig. 4, a method for controlling an external illumination lamp of a vehicle by voice is provided, which is exemplified by applying the method to a vehicle body control module in fig. 1, and comprises the following steps:
step S402, when a voice request instruction is received, detecting the state of a combination switch of a vehicle;
step S404, when the detection result is that each switch of the external illuminating lamps corresponding to the vehicle in the combined switch is in a closed state, entering a voice control mode, and responding to a voice request instruction to light or extinguish the corresponding external illuminating lamp; the external illuminating lamps comprise position lamps, dipped headlights, high beam lamps, front fog lamps and rear fog lamps;
and step S406, when the switch instruction of the combined switch is received, the voice control mode is exited, and the corresponding external illuminating lamp is lightened or extinguished in response to the switch instruction.
When the detection result is that any one switch of the external illuminating lamps corresponding to the vehicle in the combination switch is in the on state, the BCM does not respond or ignore the voice request instruction (namely does not enter the voice control mode).
Further, the specific implementation process of the step S402 and the step S404 may refer to the above contents, and will not be described herein again.
Specifically, when the BCM detects that any external light switch is turned on, the voice request command is not responded. The BCM will only execute the voice request command if all external light switches are off. If the external light is turned on by the voice command (namely, in the voice control mode), when the BCM detects that the external light switch is turned on, the BCM immediately exits the voice control mode and responds to the switch input. In summary, according to embodiments of the present invention, when the switch and voice command are simultaneously active, the BCM will respond to the switch input with a higher priority switch than voice.
Based on the invention, the BCM comprehensively judges whether to execute the voice request instruction according to the state of the combination switch and the voice request instruction; the conflict between the combination switch and the voice input can be processed, and the corresponding voice control is carried out, so that the function of the voice control external illuminating lamp is free from the dependence on the combination switch, better comfort is brought to a user, the intelligent and functional basis is met, convenience is brought, and a certain basis is laid for the realization of the unmanned technology.
To further illustrate the technical logic of the present invention, a specific voice on/off function of each external lighting lamp is taken as an example to illustrate the specific working process of the present invention:
first, voice on/off position light function: 1. the voice recognition system recognizes the on position light request and sends the request onto the CAN bus. And the BCM checks the state of the combined switch after receiving the request, controls the position lamp to be lightened if the combined switch is in an OFF gear, and does not control the position lamp to be lightened if the combined switch is not in the OFF gear. The same detection mode BCM will control the extinguishing of the position light.
The combination switch is in OFF position, and the automatic light, the dipped headlight, the high beam and the front and rear fog light switches are in OFF position.
Secondly, the function of turning on/off the dipped headlight by voice: 1. the speech recognition system recognizes the low beam light turn-on request and sends the request onto the CAN bus. The BCM checks the state of the combination switch after receiving the request, controls the position light and the dipped headlight to be simultaneously lightened if the combination switch is in an OFF gear, and does not control any light to be lightened if the combination switch is not in the OFF gear. 2. The speech recognition system recognizes the low beam light turn-off request and sends it on the CAN bus. And the BCM checks the state of the combined switch after receiving the request, controls the low-beam lamp to be turned OFF and not to be controlled to be in the position lamp state if the combined switch is in the OFF gear, and does not control any lamp to be turned OFF if the combined switch is not in the OFF gear.
Based on the legislation requirements of vehicle exterior lights, the invention can simultaneously turn on the position lights when turning on the dipped headlight, and can independently turn off the dipped headlight without influencing the position lights.
Thirdly, voice on/off of high beam function: 1. the voice recognition system recognizes the request to turn on the high beam and sends the request to the CAN bus. And the BCM checks the state of the combination switch after receiving the request, controls the position light, the dipped headlight and the high beam to be simultaneously lightened if the combination switch is in an OFF gear, and does not control any light to be lightened if the combination switch is not in the OFF gear. 2. The voice recognition system recognizes the request for turning off the high beam and sends the request to the CAN bus. And the BCM checks the state of the combination switch after receiving the request, only controls the high beam to extinguish the position lamp and the low beam if the combination switch is in an OFF gear, and does not control any lamp to extinguish if the combination switch is not in the OFF gear.
Based on the legislation requirement of vehicle exterior lights, the invention simultaneously turns on the dipped headlight and the position light when turning on the high beam.
Fourthly, the function of turning on/off the front (rear) fog lamp by voice: 1. the voice recognition system recognizes the front (rear) fog light turn-on request and sends the request to the CAN bus. The BCM checks the state of the combination switch after receiving the request, controls the position lamp, the dipped headlight and the front (rear) fog lamp to be simultaneously lightened if the combination switch is in an OFF gear, and does not control any lamp to be lightened if the combination switch is not in the OFF gear. 2. The voice recognition system recognizes the front (rear) fog light turn-off request and sends the request to the CAN bus. And the BCM checks the state of the combined switch after receiving the request, controls the front (rear) fog lamp to extinguish the states of the position lamp and the dipped headlight if the combined switch is in an OFF gear, and does not control any lamp to extinguish if the combined switch is not in the OFF gear.
Based on the invention, the BCM can process the conflict between the combination switch and the voice input to carry out corresponding voice control, and the user only needs to speak the requirement, and the complex judgment logic is judged by the BCM. The invention is not limited to the vehicle speed state, and can use the functions of voice control of the position light, the dipped headlight and the like in driving, thereby getting rid of the dependence on the combination switch and bringing better comfort to users. The invention liberates the complex logic of the user for operating the combination switch, has more convenience on the basis of meeting the requirements of intelligence and functionality, and lays a certain foundation for the realization of the unmanned technology.
In one embodiment, as shown in fig. 5, a method for controlling an external illumination lamp of a vehicle by voice is provided, which is exemplified by applying the method to a vehicle body control module in fig. 1, and comprises the following steps:
step S502, when receiving a voice request instruction, detecting the state of a combination switch of a vehicle;
step S504, when the detection result is that each switch of the external illuminating lamps corresponding to the vehicle in the combined switch is in a closed state, entering a voice control mode, and responding to a voice request instruction to light on or turn off the corresponding external illuminating lamps; the external illuminating lamps comprise position lamps, dipped headlights, high beam lamps, front fog lamps and rear fog lamps;
step S506, when the switch instruction of the combined switch is received, the voice control mode is exited, and the corresponding external illuminating lamp is turned on or turned off in response to the switch instruction.
Step S508, when the voice request instruction is confirmed to be the instruction for turning on the function of accompanying self-returning and the vehicle is in a power-off flameout state of the whole vehicle, entering a voice control mode, responding to the instruction for turning on the function of accompanying self-returning, and turning on a position light and a dipped headlight for timing; at the end of the timing, the position lights and the low beam lights are turned off.
It should be noted that, for the specific implementation process of the step S502, the step S504, and the step S506, reference may be made to the above contents, and details are not repeated here.
Among other things, the Follow me home function (Follow me) functions to turn off the ignition switch and turn on the driver's doors in the dark to illuminate the environment around the vehicle. Meanwhile, the front fog lamp, the tail lamp and the license plate lamp are also turned on, and the lights are automatically turned off after being turned on for a period of time. The traditional function of accompanying with me to go home is usually turned on only by operating a combination switch according to certain operation logic, and the operation logic of each model of vehicle is different.
Further, the invention can open the function of accompanying me to come home by voice: in the whole vehicle powering-off flameout certain time, the voice recognition system recognizes that the function of accompanying self-returning is turned on, the signal is sent to the bus, the BCM does not check the state of the combination switch after receiving the signal, and the position light and the dipped headlight are directly controlled to be turned on and timed. And after the timing is finished, the position light and the dipped headlight are controlled to be turned off and the state of the combined switch is checked.
Specifically, the function of accompanying self to go home is allowed to be turned on only within a certain time when the whole vehicle is powered off (namely, within a certain time after the power is powered off). Vehicle power can be saved; after the vehicle is powered off, the dipped headlight, the high beam and the front fog light and the rear fog light do not work, so that the state of the combination switch does not need to be checked. After the timing is finished, if the position lamp switch is turned on by voice (or by a switch), the position lamp can still be turned on based on the strategy of the invention. Because the position lamp can work after the whole vehicle is powered off.
Based on the invention, the voice control accompanied with the function of returning home liberates the complex logic of the user operation combination switch, is more convenient to use, and simultaneously enables the vehicle to be more intelligent. The invention provides a scheme that a user only needs to speak out a requirement and the complex judgment logic is judged by BCM software aiming at the problem of complex logic of a combination switch. Since the voice control system is not limited to the vehicle speed state, the voice control of the external light in the driving process is convenient and intelligent.
It should be understood that although the steps in the flowcharts of fig. 2, 4 and 5 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2, 4, and 5 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or stages is not necessarily sequential, but may be performed alternately or alternatingly with other steps or at least some of the sub-steps or stages of other steps.
In one embodiment, as shown in fig. 6, there is provided an apparatus for voice-controlling an exterior illumination lamp of a vehicle, including:
the state detection module 610 is used for detecting the state of a combination switch of the vehicle when receiving a voice request instruction;
the instruction response module 620 is configured to enter a voice control mode when the detection result is that each switch of the external illumination lamps corresponding to the vehicle in the combination switch is in an off state, and turn on or off the corresponding external illumination lamps in response to the voice request instruction; the exterior lights include position lights, dipped headlights, high beams, front fog lights, and rear fog lights.
The voice request instruction is transmitted through a CAN bus when the voice recognition system recognizes a request of turning on or turning off any external illuminating lamp by voice. Further, the voice request command may be a CAN bus signal of the event type message.

In one embodiment, further comprising:
and the switch instruction module is used for exiting the voice control mode and responding to the switch instruction to light or extinguish the corresponding external illuminating lamp when receiving the switch instruction of the combined switch.

All or part of each module in the device for controlling the vehicle external illuminating lamp through voice can be realized through software, hardware and a combination thereof. The modules can be embedded in a hardware form or independent from a processor in the computer device, and can also be stored in a memory in the computer device in a software form, so that the processor can call and execute operations corresponding to the modules.
