Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The on-off control of the conventional vehicle atmosphere lamp is generally realized by depending on the position lamp switch control. The position light switch is a physical switch for turning on or off the position light. For example, a user operates a position light switch, so that when the position light is turned on, the atmosphere light is turned on along with the turning on of the position light; when the user controls the position lamp switch, the atmosphere lamp is turned off along with the turning-off of the position lamp when the position lamp is turned off. The on-off control of the traditional vehicle atmosphere lamp is realized by depending on the position lamp switch control, and when the traditional atmosphere lamp on-off control and the existing sound request control are comprehensively controlled, the situation that the atmosphere lamp is automatically turned on after the sound control is turned off occurs. The control logic of the traditional technology atmosphere lamp needs to follow the state of the position lamp, the operation logic is complex, and the convenience is poor.
The vehicle atmosphere lamp control method provided by the invention can be applied to the application environment shown in figure 1. Wherein the voice recognition system 120 communicates with the BCM (body control module) 110 through a bus, and the mood light 130, the position light 140, and the position light switch 150 communicate with the BCM (body control module) 110. According to the embodiments of the invention, when the sound request instruction (the sound turn-on atmosphere lamp instruction and/or the sound turn-off atmosphere lamp instruction) is acquired, the BCM can make a logical judgment according to the position lamp switch state and the position lamp state to control the turning on and off of the atmosphere lamp. The dependence on the state of the position lamp is eliminated, the user can directly control the opening and closing of the atmosphere lamp, the light control mode of the atmosphere lamp is diversified, and better convenience and practicability are brought.
In one embodiment, as shown in fig. 2, a vehicular ambience lamp control method is provided, which is described by taking the method as an example applied to the BCM in fig. 1, and comprises the following steps:
step S110, detecting the current control state of the vehicle atmosphere lamp when a sound atmosphere lamp closing instruction is obtained; if the current control state is detected to be the following opening state, the atmosphere lamp is turned off, and the current control state is changed into a sound closing state; the follow-on state is a control state in which the atmosphere lamp is lit following the turning on of the position lamp.
Wherein, the sound turn-off atmosphere lamp instruction refers to a request instruction for turning off the atmosphere lamp by a sound command. The current control state refers to a control state in which the ambience lamp is currently on or currently off. The sound-off state refers to a control state in which the atmosphere lamp can be turned off according to a sound-off atmosphere lamp instruction. The vehicle atmosphere lamp can be an interior atmosphere lamp or an exterior atmosphere lamp. When the voice recognition system recognizes the command of turning off the atmosphere lamp by voice, the recognized command of turning off the atmosphere lamp by voice is transmitted to a vehicle body control module (hereinafter referred to as BCM) through a bus.
Specifically, after obtaining the sound turn-off atmosphere lamp command transmitted by the sound recognition system, the BCM detects the current control state of the vehicle atmosphere lamp. And if the BCM detects that the current control state of the atmosphere lamp is the following opening state, the BCM extinguishes the atmosphere lamp and changes the current control state of the atmosphere lamp into the sound closing state. Further, when the BCM detects that the current control state of the atmosphere lamp is a control state in which the atmosphere lamp is turned on following the turning-on of the position lamp, the BCM may turn off the atmosphere lamp and change the current control state of the atmosphere lamp to a sound-off state.
For example, when the user starts the ON gear of the vehicle and operates the position light switch to turn ON the position light, if the atmosphere light is turned ON following the turning ON of the position light, that is, the current control state of the atmosphere light is the following turning ON state. At this time, if the BCM acquires a voice atmosphere lamp closing instruction and further detects that the current control state of the atmosphere lamp is a following on state, the BCM turns off the atmosphere lamp and changes the current control state of the atmosphere lamp to a voice closing state.
It should be noted that, after acquiring the sound atmosphere lamp turning-off instruction transmitted by the sound recognition system, the BCM detects the current control state of the vehicle atmosphere lamp, and if the BCM detects that the current control state of the atmosphere lamp is the control state in which the atmosphere lamp is turned off following the turning-off of the position lamp, the BCM keeps turning off the atmosphere lamp.
Step S120, detecting the current control state of the atmosphere lamp when the atmosphere lamp opening instruction is obtained; if the current control state is detected to be the following closing state, the atmosphere lamp is lightened, and the current control state is changed into a sound opening state; the follow-off state is a control state in which the atmosphere lamp is turned off following the turning-off of the position lamp.
The voice atmosphere lamp turning-on instruction refers to a request instruction for turning on the atmosphere lamp by using a voice command. The sound on state refers to a control state in which the ambience lamp may be lit according to the sound on ambience lamp instruction. When the voice recognition system recognizes the voice turn-on ambience light command, the recognized voice turn-off ambience light command is transmitted to the BCM through the bus.
Specifically, after obtaining the sound atmosphere lamp opening instruction transmitted by the sound recognition system, the BCM detects the current control state of the vehicle atmosphere lamp. And if the BCM detects that the current control state of the atmosphere lamp is the following closing state, the BCM lights the atmosphere lamp and changes the current control state of the atmosphere lamp into the sound opening state. Further, when the BCM detects that the current control state of the atmosphere lamp is a control state in which the atmosphere lamp is turned off along with the turning-off of the position lamp, the BCM turns on the atmosphere lamp and changes the current control state of the atmosphere lamp into a sound turning-on state.
For example, when the user operates the position light switch to turn off the position light, if the atmosphere light is turned off following the turning off of the position light, the current control state of the atmosphere light is the following turning off state. At this time, if the BCM acquires a voice atmosphere lamp turning-on instruction and detects that the current control state of the atmosphere lamp is the following turning-off state, the BCM lights the atmosphere lamp and changes the current control state of the atmosphere lamp to the voice turning-on state.
It should be noted that, after acquiring the sound atmosphere lamp turning-on command transmitted by the sound recognition system, the BCM detects the current control state of the vehicle atmosphere lamp, and if the BCM detects that the current control state of the atmosphere lamp is the control state in which the atmosphere lamp is turned on following the turning-on of the position lamp, the BCM keeps turning on the atmosphere lamp, and changes the current control state of the atmosphere lamp to the sound turning-on state.
For example, when the user starts the ON gear of the vehicle and operates the position light switch to turn ON the position light, if the atmosphere light is turned ON following the turning ON of the position light, that is, the current control state of the atmosphere light is the following turning ON state. At this time, if the BCM acquires a voice atmosphere lamp turning-on instruction and detects that the current control state of the atmosphere lamp is the following turning-on state, the BCM keeps turning on the atmosphere lamp and changes the current control state of the atmosphere lamp to the voice turning-on state.
Further, the BCM may communicate with the voice recognition system via a CAN Area Network (Controller Area Network). When the voice recognition system recognizes a request of turning on or turning off the atmosphere lamp by voice, the voice recognition system sends a bus signal including an event type to the BCM through the CAN bus, the BCM acquires a command of turning on or turning off the atmosphere lamp by voice, and makes a logic judgment according to the current control state of the atmosphere lamp to control the on or off of the atmosphere lamp. The voice recognition system can recognize sound waves with preset rules, such as tapping sound with preset rules, voice produced by a human body and the like.
Further, the sound turn-off atmosphere lamp instruction is a CAN bus signal of an event type message; the sound turn-on atmosphere lamp instruction is a CAN bus signal of an event type message.
It should be noted that the invention selects the event message of the CAN bus signal as the command of turning off the atmosphere lamp by sound and/or the command of turning on the atmosphere lamp by sound; the event type message corresponds to a status type message. The event message refers to a message sent intermittently, such as a command for turning off or turning on the atmosphere lamp by sound. And the status type message refers to a message which is continuously transmitted, such as a command of a position light switch.
The method selects the event type message of the CAN bus signal as the voice turn-off atmosphere lamp instruction and/or the voice turn-on atmosphere lamp instruction, takes the voice turn-off atmosphere lamp instruction and/or the voice turn-on atmosphere lamp instruction as the highest priority control, CAN directly embody the intention of a user, CAN overcome the condition that the atmosphere lamp is automatically turned on after being turned off by voice, is convenient to use, and improves the user experience.
In the above embodiment, the BCM can comprehensively determine whether to turn on or turn off the atmosphere lamp according to the position lamp on-off state and the position lamp state when acquiring the sound request command (the sound turn-off atmosphere lamp command or the sound turn-on atmosphere lamp command). The dependence on the state of the position lamp is eliminated, the user can directly control the opening and closing of the atmosphere lamp, the light control mode of the atmosphere lamp is diversified, and better convenience and practicability are brought.
In one embodiment, as shown in fig. 3, a vehicular ambience lamp control method is provided, which is described by taking the method as an example applied to the BCM of fig. 1, and comprises the following steps:
step S210, detecting the current control state of the vehicle atmosphere lamp when the sound atmosphere lamp closing instruction is obtained; if the current control state is detected to be the following opening state, the atmosphere lamp is turned off, and the current control state is changed into a sound closing state; the follow-on state is a control state in which the atmosphere lamp is lit following the turning on of the position lamp.
Step S220, detecting the current control state of the atmosphere lamp when the atmosphere lamp opening instruction is obtained; if the current control state is detected to be the following closing state, the atmosphere lamp is lightened, and the current control state is changed into a sound opening state; the follow-off state is a control state in which the atmosphere lamp is turned off following the turning-off of the position lamp.
In step S230, when the current control state is the sound off state and the position light on command is obtained, the atmosphere light is turned on, and the current control state is changed to the following on state.
The specific content process of step S210 and step S220 may refer to the above contents, and is not described herein again.
Specifically, when the user operates the position lamp switch to turn on the position lamp, the BCM acquires a position lamp turn-on instruction transmitted by the position lamp switch. When the BCM obtains a position lamp opening instruction, the current control state of the atmosphere lamp is detected, if the current control state of the atmosphere lamp is a sound closing state, the atmosphere lamp is lightened, and the current control state of the atmosphere lamp is changed into a following opening state.
Based on the embodiment, when the sound request instruction (the sound turn-off atmosphere lamp instruction or the sound turn-on atmosphere lamp instruction) is acquired, the BCM can comprehensively judge whether to turn on or turn off the atmosphere lamp according to the position lamp on-off state and the position lamp state. The dependence on the state of the position lamp is eliminated, the user can directly control the opening and closing of the atmosphere lamp, the light control mode of the atmosphere lamp is diversified, and better convenience and practicability are brought.
In one embodiment, as shown in fig. 4, a flow chart of the sound state switching step is shown. The method is illustrated by being applied to the BCM in fig. 1 as an example, and comprises the following steps:
step S310, detecting the current control state of the vehicle atmosphere lamp when the atmosphere lamp opening command is obtained; and if the current control state is detected to be the sound closing state, lighting the atmosphere lamp, and changing the current control state into the sound opening state.
Specifically, when the BCM acquires a voice turn-on atmosphere lamp instruction transmitted by a voice recognition system, the current control state of the atmosphere lamp is detected, and if the current control state of the atmosphere lamp is a voice turn-off state, the atmosphere lamp is turned on and the current control state of the atmosphere lamp is changed into a voice turn-on state, so that the atmosphere lamp is turned on under voice control.
Step S320, detecting the current control state of the atmosphere lamp when the instruction of closing the atmosphere lamp by sound is obtained; and if the current control state is detected to be the sound on state, the atmosphere lamp is extinguished, and the current control state is changed into the sound off state.
Specifically, when the BCM acquires a sound turning-off atmosphere lamp instruction transmitted by a sound recognition system, the current control state of the atmosphere lamp is detected, if the current control state of the atmosphere lamp is a sound turning-on state, the atmosphere lamp is turned off, the current control state of the atmosphere lamp is changed into a sound turning-off state, and the purpose of turning off the atmosphere lamp under sound control is achieved.
According to the embodiment, when the current control state of the atmosphere lamp is the sound control state (sound on or off state), the BCM acquires the sound request instruction (sound on or off atmosphere lamp instruction), and the BCM can determine whether to turn on or turn off the atmosphere lamp according to the sound request instruction in the sound control state. Has better convenience and practicability.
In one embodiment, as shown in FIG. 5, a flow chart following the state switching step is shown. The method is illustrated by being applied to the BCM in fig. 1 as an example, and comprises the following steps:
and step S410, when the current control state is the following opening state and the position lamp closing instruction is obtained, turning off the atmosphere lamp, and changing the current control state into the following closing state.
Specifically, when the user operates the position lamp switch to turn off the position lamp, the BCM acquires a position lamp turn-off instruction transmitted by the position lamp switch. When the BCM acquires a position lamp closing instruction, the current control state of the atmosphere lamp is detected, if the current control state of the atmosphere lamp is a following opening state, the atmosphere lamp is turned off, the current control state of the atmosphere lamp is changed into a following closing state, and the position lamp is turned off under the control of a position lamp switch.
Step S420, when the current control state is the following off state and the position light on instruction is obtained, the atmosphere light is turned on, and the current control state is changed to the following on state.
Specifically, when the user operates the position lamp switch to turn on the position lamp, the BCM acquires a position lamp turn-on instruction transmitted by the position lamp switch. When the BCM obtains a position lamp opening instruction, the current control state of the atmosphere lamp is detected, if the current control state of the atmosphere lamp is the following closing state, the atmosphere lamp is lightened, and the current control state of the atmosphere lamp is changed into the following opening state. The position lamp switch is controlled to light the atmosphere lamp.
Based on this embodiment, when the current control state of the atmosphere lamp is the following position lamp switch control state (following on or off state), the BCM obtains a position lamp switch request instruction (position lamp switch on or off atmosphere lamp instruction), and the BCM can determine whether to turn on or turn off the atmosphere lamp according to the position lamp switch instruction in the following position lamp switch control state.
In one embodiment, as shown in fig. 6, a method for controlling a vehicular ambience lamp is provided, which is described by taking the method as an example applied to the BCM in fig. 1, and includes the following steps:
step S510, searching a control zone bit of the atmosphere lamp when the atmosphere lamp closing instruction is obtained; if the control flag bit is found to be the flag bit marked with the on state, the atmosphere lamp is turned off, and the control flag bit is changed into the flag bit marked with the sound off state.
The BCM can obtain the current control state of the atmosphere lamp by searching the control zone bit of the atmosphere lamp.
Specifically, after acquiring the sound atmosphere lamp turning-off instruction transmitted by the sound identification system, the BCM queries a control flag bit of the vehicle atmosphere lamp. And if the control zone bit of the atmosphere lamp is found to be the zone bit marked to follow the on state by the BCM, turning off the atmosphere lamp and changing the control zone bit of the atmosphere lamp into the zone bit in the sound off state.
Step S520, searching a control zone bit of the atmosphere lamp when the atmosphere lamp opening instruction is obtained; and if the control zone bit is found to be the zone bit with the mark following the off state, lighting the atmosphere lamp, and changing the control zone bit into the zone bit with the mark sound on state.
Specifically, after acquiring the sound atmosphere lamp opening instruction transmitted by the sound recognition system, the BCM queries a control flag bit of the vehicle atmosphere lamp. And if the control flag bit of the atmosphere lamp is found to be the flag bit marked to follow the off state by the BCM, the atmosphere lamp is lightened, and the control flag bit of the atmosphere lamp is changed into the flag bit in the sound on state. Further, the control flag bit of the atmosphere lamp can be obtained by querying a lookup table.
Based on the embodiment, when the sound request instruction is acquired, the BCM can make a logical judgment according to the position light switch state and the position light state to control the turning on and off of the atmosphere light. The dependence on the state of the position lamp is eliminated, the user can directly control the opening and closing of the atmosphere lamp, the light control mode of the atmosphere lamp is diversified, and better convenience and practicability are brought.
In one embodiment, the voice turn on mood light command is a voice turn on mood light command; the voice turn-off atmosphere light instruction is a voice turn-off atmosphere light instruction.
The voice recognition system may pre-store voice data to be recognized, for example, the voice recognition system pre-stores voice data of "turning on the atmosphere lamp" and "turning off the atmosphere lamp". When a user needs to turn on the atmosphere lamp by voice, the voice of turning on the atmosphere lamp CAN be sent out, and when the voice of turning on the atmosphere lamp sent out by the user is matched with the pre-stored voice, the voice recognition system transmits a voice atmosphere turning-on instruction to the BCM through the CAN bus; when a user needs to turn off the atmosphere lamp by voice, the voice of turning off the atmosphere lamp CAN be sent out, and when the voice of turning off the atmosphere lamp sent out by the user is matched with the pre-stored voice, the voice recognition system transmits the voice turning off atmosphere command to the BCM through the CAN bus.
Specifically, when the BCM acquires a voice atmosphere lamp closing instruction, if the current control state is detected to be a following opening state, the BCM extinguishes the atmosphere lamp and changes the current control state into a sound closing state; when the BCM obtains a voice atmosphere lamp opening instruction, if the current control state is detected to be the following closing state or the following opening state, the BCM lights the atmosphere lamp and changes the current control state into the sound opening state. The user can be directly through opening and closing of speech control atmosphere lamp, and better convenience and practicality have been brought to diversified atmosphere lamp light control mode.
To further illustrate the technical logic of the present invention, the control of the vehicle atmosphere light is divided into a voice control mode and a position light switch control mode. The voice control mode comprises a voice closing state and a voice opening state; the position light switch control mode includes a follow on state and a follow off state. As shown in fig. 7, the status jump procedure of the vehicle atmosphere lamp control is as follows:
s710, when the atmosphere lamp is in the voice off state and the voice atmosphere lamp on command is received, the BCM lights the atmosphere lamp and changes the current control state of the atmosphere lamp to the voice on state.
S720, when the atmosphere lamp is in the voice on state and the voice atmosphere lamp off instruction is received, the BCM extinguishes the atmosphere lamp and changes the current control state of the atmosphere lamp into the voice off state.
