Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The following describes a vehicle, a vehicle body control system, a control method and apparatus, and a storage medium according to an embodiment of the present invention with reference to the accompanying drawings.
Fig. 1 is a block diagram of a vehicle according to an embodiment of the present invention.
As shown in fig. 1, the vehicle includes a plurality of sets of lamps, respectively, a first set of lamps 20, a second set of lamps 21, …, and an nth set of lamps 2n. The vehicle further includes a plurality of body area control devices such as a first body area control device 10, second body area control devices 11, …, and an nth body area control device 1 n. The body area control devices are connected with the lamps in a one-to-one correspondence manner, namely, the first body area control device 10 is connected with a first group of lamps 20, the second body area control device 11 is connected with a second group of lamps 21, and so on. Alternatively, the set of lights may be lights attached to one side of the vehicle, such as the left side of the vehicle including a left turn light or the like, and the right side including a right turn light or the like.
The vehicle lamp synchronous control method is applied to a vehicle body domain control device of the vehicle.
Fig. 2 is a flowchart of a lamp synchronization control method according to an embodiment of the present invention.
As shown in fig. 2, the vehicle lamp synchronization control method includes the steps of:
s10, when a first group of lamps is controlled according to a first lamp control instruction, first lamp state information fed back by the first group of lamps is obtained.
S20, acquiring state information of other groups of car lights.
Specifically, in this embodiment, the lamp may be controlled by the body area control device of the vehicle. Taking the description of the synchronous control of the first group lamp 20 and the second group lamp 21 of the vehicle as an example, it is understood that, when the first group lamp is controlled according to the first light control instruction after the vehicle is powered on, the first lamp state information of the first group lamp 20 is acquired, and the state information of the second group lamp transmitted by the second body domain control device 11 connected to the second group lamp 21 is acquired. The state information may be state information when the last vehicle lamp finishes working, and each group of vehicle lamps may feed back the corresponding state information to the corresponding vehicle body domain control device.
In some examples of the present invention, the vehicle body domain control devices are connected through a vehicle body network communication to obtain state information of other groups of vehicle lights, including: and receiving state information of other groups of lamps sent by other vehicle body domain control devices through a vehicle body network, wherein the state information of the other groups of lamps comprises second vehicle lamp state information corresponding to a second group of lamps.
As shown in fig. 1, the first body area control device 10 and the second body area control device 11 may be connected through a body network, and it should be noted that each body area control device may be connected through a body network (not shown in the drawing), so that each body area control device may send status information of a group of lamps controlled by the corresponding body area control device to the other body area control device. Optionally, the body area control devices may be communicatively connected through a CAN (Controller Area Network ) and/or LIN (Local Interconnect Network, local interconnect network) bus.
S30, judging whether the first light control instruction needs to be adjusted according to the first light state information and state information of other groups of lights.
Specifically, after the first lamp state information and the state information of other groups of lamps are obtained, the information is judged, so that whether the first lamp control instruction needs to be adjusted or not is obtained. It should be noted that, when the first group of lamps 20 and the other groups of lamps do not work synchronously, it indicates that the first light control instruction needs to be adjusted so that the first group of lamps 20 and the other groups of lamps can work synchronously; when the first group lamp 20 is operated in synchronization with the other groups of lamps, it means that the first light control command does not need to be adjusted. The comparison may be performed by setting a preset value, specifically, if the interval time between the flicker of the first group of lamps 20 and the other group of lamps is smaller than the preset value, the first group of lamps 20 and the other group of lamps may be considered to be synchronous, otherwise, the first group of lamps 20 and the other group of lamps may be considered to be asynchronous.
S40, if the first light control instruction needs to be adjusted, the first light control instruction is adjusted according to the first light state information and the state information of the other groups of lights, and the first group of lights are controlled according to the adjusted first light control instruction, so that the first group of lights and the other groups of lights work synchronously.
Specifically, if it is determined in step S30 that the first light control instruction needs to be adjusted, when the first light control instruction is received to control the first group of lamps 20, the first group of light control instructions may be adjusted by the first lamp state information obtained in the above steps and the state information of the other groups of lamps. For example, in the case where the first group lamp 20 and the second group lamp 21 need to be started synchronously, when the first light control command controls the first group lamp 20, the first light control command is adjusted according to the first lamp state information and the state information of the second group lamp because the first light control command controlling the first group lamp 20 and the second light control command controlling the second group lamp 21 need to be processed synchronously.
More specifically, after the first light control command is obtained by adjustment, the adjusted first light control command is used to control the first group of lamps 20, so as to control the first group of lamps 20 to work synchronously with other groups of lamps. For example, the first light control command is adjusted according to the first light state information and the second light state information, so that the first group of lights 20 and the second group of lights 21 can work synchronously, thereby completing the control of the lights, such as dual flash control.
In some examples of the present invention, after the first light state information is obtained, the first light state information may be further sent to other vehicle body domain control devices, where if the first light control command does not need to be adjusted, the other vehicle body domain control devices adjust the corresponding light control command according to the first light state information and the state information of the corresponding group of lights.
Specifically, when the first lamp state information is acquired after the vehicle is powered on, the first lamp state information is sent to other vehicle body domain control devices through the vehicle network, wherein if the first lamp control instruction does not need to be adjusted, after each vehicle body domain control device receives the first lamp state information, the corresponding lamp control instruction can be adjusted according to the first lamp state information and the state information of the corresponding group of lamps, and the control of the lamps of the group corresponding to the vehicle body domain control device is completed according to the adjusted lamp control instruction, so that the lamps of other groups can synchronously complete work with the lamps 20 of the first group.
For example, after the vehicle is powered on, the first light state information is sent to the second body area control device 11, and after the second body area control device 11 receives the first light state information, the second light state information is combined to adjust a second light control instruction corresponding to the second group of lamps 21, and then the second group of lamps 21 are controlled according to the adjusted second light control instruction, so that the first group of lamps 20 and the second group of lamps 21 can run synchronously.
In some examples of the present invention, optionally, the state information of the other set of lamps includes second lamp state information corresponding to the second set of lamps, the second lamp state information includes a second lamp actual blinking frequency, the first lamp state information includes a first lamp actual blinking frequency, and determining whether the first lamp light control command needs to be adjusted includes comparing a relationship between the first lamp actual blinking frequency and the second lamp actual blinking frequency; if the actual flicker frequency of the first vehicle lamp is larger than the actual flicker frequency of the second vehicle lamp, judging that the first light control instruction needs to be adjusted; if the actual flicker frequency of the first lamp is smaller than or equal to the actual flicker frequency of the second lamp, the first lamp control command is judged not to need to be adjusted.
In this embodiment, the second light status information includes a second actual flashing frequency of the vehicle lamp, the first light status information includes a first actual flashing frequency of the vehicle lamp, and adjusting the first light control command based on the first light status information and status information of the other group of vehicle lamps includes: calculating a first difference between the actual flicker frequency of the second lamp and the actual flicker frequency of the first lamp; and if the first difference value is larger than or equal to the first preset difference value, adjusting the first light control instruction so that the first difference value is smaller than the first preset difference value.
Specifically, the flicker frequency is an important factor for determining whether the two lights are synchronized, in this embodiment, it is understood that the first light status information may include the (actual) flicker frequency of the first group of lamps 20, the second light status information may include the (actual) flicker frequency of the second group of lamps 21, and the first body domain control device 10 may obtain the corresponding actual flicker frequencies of the first and second lamps from the first and second light status information, for example, the actual flicker frequency fed back at the end of each group of last operation. After the first body area control device 10 obtains the flicker frequencies of the first group of lamps 20 and the second group of lamps 21, the two flicker frequencies are subjected to a difference processing to obtain a first difference value, and the magnitude of the first difference value determines the flicker difference between the first group of lamps 20 and the second group of lamps 21. The first preset difference set in this embodiment may be a critical frequency value that can be distinguished by the human eye whether the first group of lamps 20 and the second group of lamps 21 flash synchronously. When the first difference is smaller than the first preset difference, the first group of lamps 20 and the second lamp 21 can work synchronously; when the first difference is greater than the first preset difference, the first body control device 10 adjusts the first light control command so that the first difference is smaller than the first preset difference, and thus the first group of lamps 20 and the second group of lamps 21 are controlled to synchronously work, i.e. to synchronously flash.
It will be appreciated that the second light status information may also be sent to the first body domain control device 11 by the first body domain control device 10, so that the second body domain control device 11 adjusts the second light control command to complete the synchronous control of the first group light 20 and the second group light 21.
It should be noted that the above embodiments only describe examples of two vehicle body area control devices, and the present invention may also complete synchronous control of more area vehicle lamps by providing more than two vehicle body area control devices.
In this example, the first light status information further includes a first light target flashing frequency, the second light status information further includes a second light target flashing frequency, and the adjusting the first light control instructions according to the first light status information and the status information of the other group of lights further includes: calculating a second difference between the second lamp target flicker frequency and the first lamp target flicker frequency; if the second difference is smaller than the second preset difference, calculating a first difference between the actual flicker frequency of the second vehicle lamp and the actual flicker frequency of the first vehicle lamp; and if the first difference value is larger than or equal to the first preset difference value, adjusting the first light control instruction so that the first difference value is smaller than the first preset difference value.
Specifically, after the second body area control device 11 receives the second light status information of the second group of lamps 21, the second body area control device 11 determines a second target flashing frequency of the second group of lamps 21 according to the second light status information, and the first body area control device 10 determines a first target flashing frequency of the first group of lamps 20 according to the first light status information, wherein the first target flashing frequency and the second target flashing frequency are determined according to the control frequency sent by the lamp control command. Then, the second body area control device 11 calculates and records a difference between the second lamp target blinking frequency and the first lamp target blinking frequency as a second difference, determines the second difference, and when the second difference is smaller than a second preset difference, it indicates that the difference between the first lamp target blinking frequency and the second lamp target blinking frequency is negligible, and no adjustment is required, so that the determination of the blinking frequency can be performed. And calculating the difference between the flicker frequency of the second group of lamps 21 and the flicker frequency of the first group of lamps 20, recording the difference as a first difference, judging the first difference, and adjusting the second light control instruction when the first difference is larger than or equal to a first preset difference, so that the first difference is smaller than the first preset difference, thereby completing the adjustment of the second light control instruction, and synchronously controlling the second lamp and the first lamp.
It should be noted that the second preset difference is a critical frequency value that can be distinguished by human eyes whether the two lamps flash synchronously.
In this example, adjusting the first light control instruction according to the first light status information and status information of the other group of lights further comprises: if the second difference is greater than or equal to the second preset difference, calculating a third difference between the actual flashing frequency of the first lamp and the target flashing frequency of the first lamp, and calculating a fourth difference between the actual flashing frequency of the second lamp and the target flashing frequency of the second lamp; calculating a first ratio between the third difference and the second target flicker frequency of the vehicle lamp, and calculating a second ratio between the fourth difference and the first target flicker frequency of the vehicle lamp; calculating a fifth difference between the first ratio and the second ratio; and if the fifth difference value is greater than or equal to the third preset difference value, adjusting the first light control signal so that the fifth difference value is smaller than the third preset difference value.
Specifically, after the second difference between the second target flashing frequency of the vehicle lamp and the first target flashing frequency of the vehicle lamp is calculated, if the second difference is greater than or equal to the second preset difference, it is indicated that the current target flashing frequency of the first vehicle lamp and the second target flashing frequency of the vehicle lamp do not meet the requirement of controlling the synchronous control of the first group of vehicle lamps and the second group of vehicle lamps, and at the moment, the two lamps can be considered to work differently, namely flashing at different frequencies is obviously distinguished, so that corresponding function prompt is realized. Further calculating a difference between the actual flashing frequency of the first vehicle lamp and the target flashing frequency of the first vehicle lamp, and recording the difference as a third difference, and calculating a difference between the actual flashing frequency of the second vehicle lamp and the target flashing frequency of the second vehicle lamp, and recording the difference as a fourth difference; after the third difference value and the fourth difference value are obtained, calculating a first ratio between the third difference value and a second target flicker frequency of the vehicle lamp and a second ratio between the fourth difference value and the first target flicker frequency of the vehicle lamp; and then, the first ratio and the second ratio are subjected to difference to obtain a fifth difference value, the fifth difference value is judged, and if the fifth difference value is larger than or equal to a third preset difference value, the second light control instruction is adjusted so that the fifth difference value is smaller than the third preset difference value. Therefore, the first group of lamps and the second group of lamps can always keep obvious differential flicker by controlling the same proportion deviation between the first group of lamps and the second group of lamps and the corresponding target frequency.
As an example, the first light status information further includes a first light power, the second light status information further includes a second light power, and the first light control command is adjusted according to the first light status information and status information of other groups of lights, and specifically further includes: calculating a sixth difference between the second lamp power and the first lamp power; if the sixth difference is smaller than the fourth preset difference, the step of calculating a second difference between the target flicker frequency of the second car light and the target flicker frequency of the first car light is skipped, so that synchronous control of the two groups of car lights is realized.
When the plurality of vehicle body domain control devices each receive the lamp state information sent by the other vehicle body domain control device, it may be agreed that certain lamp state information (for example, the first lamp state information) is the reference information, and the other vehicle body domain control devices all perform instruction adjustment based on the reference information. The provisioning method may be to fix a certain vehicle body control device, or may be based on a vehicle body control device corresponding to a vehicle lamp having a minimum difference between an actual flicker frequency and a target flicker frequency.
In one embodiment of the present invention, as shown in fig. 3, the first body domain control device 10 is provided at a main driving position of the vehicle, and the second body control device 11 is provided at a co-driving position of the vehicle.
Further, referring to fig. 3, the plurality of body domain control modules further includes a third body domain control device 12, the third body domain control device 12 being disposed at a rear row position of the vehicle.
Specifically, as shown in fig. 3, three vehicle body domain control devices, namely a first vehicle body domain control device 10, a second vehicle body domain control device 11 and a third vehicle body domain control device 12, are arranged on the vehicle body, and are respectively arranged at a main driving position, a copilot position and a rear row position for facilitating control of vehicle-mounted electric appliances in different areas, so that the wiring control can be realized, and the use amount of wiring harnesses is saved. The three body area control devices may be communicatively connected to each other via a CAN bus, but may be communicatively connected to each other via a LIN bus (not shown).
Alternatively, referring to fig. 3, the second vehicle body domain control device 11 in the co-driving position may correspondingly control the load unit to include not only the vehicle lamp but also at least one of the following vehicle-mounted electric appliances: right door handle, right side car light, right side outside rear-view mirror, washing motor, skylight, right side air bag/area, indoor light, distribution device, inside rear-view mirror, air conditioner, secondary driving seat, right side door/window. That is, the second vehicle body domain control device 11 may integrate the control functions of the plurality of in-vehicle electrical devices.
In summary, the vehicle lamp synchronous control method provided by the embodiment of the invention can reduce the cost of vehicle body control, realize synchronous control of the vehicle lamp and does not need a complex lamplight synchronous protocol.
