[0002] At present, more and more vehicles have hidden door handles designed to be pushed out and retracted by actuators. However, in high-altitude cold areas or cold working conditions, such as rain and snow, hidden door handles are prone to freezing after being retracted, causing the door handles to be unable to pop out, resulting in the door being unable to open and the user being unable to use the vehicle normally. At the same time, in order to meet the current needs of integrating automotive electronic and electrical architecture from distributed to centralized, domain controllers came into being.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0057] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.
[0058] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0059] Example 1
[0060] See also Figure 1 and Figure 2 , is a flow chart of an embodiment of a hidden door handle antifreeze control method provided by the present invention, the method includes steps 101 to 105, each step is specifically as follows:
[0061] Step 101: Collect environmental information within a preset time in real time, and compare the environmental information with preset environmental threshold conditions.
[0062] In the first embodiment, the hidden door handle antifreeze control system is provided with a low temperature antifreeze mode and a normal mode, and the two modes can be switched according to actual conditions. By collecting environmental information outside the vehicle in real time, the vehicle can be automatically adjusted to enter the low temperature antifreeze mode or the normal mode to control the door handle state of the hidden door handle to meet the user's vehicle use needs.
[0063] Furthermore, in the first embodiment, the environmental information within a preset time is collected in real time, specifically:
[0064] Use optical rainfall sensors to collect current rainfall information in real time;
[0065] Use temperature sensors to collect current temperature information in real time;
[0066] Using the networking system to obtain weather status information for a preset future time period;
[0067] The current rainfall information, the current temperature information and the weather status information of a preset future time period are determined as the environmental information within the preset time period.
[0068] In the first embodiment, when the vehicle is in motion or locked, the light and rainfall sensors and temperature sensors can collect the current ambient temperature and rainfall information; the networked system can obtain the weather characteristics in the future period to predict the ambient temperature in the future period, where the future period can be customized, such as 12 hours. After receiving the outside temperature and light and rainfall information obtained by the sensor, combined with the weather status information of the future period obtained by the networked system, the environmental information for low temperature judgment is formed, and compared with the preset environmental threshold conditions, it can be judged whether it is necessary to enter the low temperature antifreeze mode at this time.
[0069] Further, in the first embodiment, the environmental information is compared with a preset environmental threshold condition, specifically:
[0070] Determine the current ambient temperature outside the vehicle according to the current rainfall information and the current temperature information in the environmental information;
[0071] Predicting the ambient temperature outside the vehicle in a preset future time period according to the weather status information in the preset future time period;
[0072] Comparing the current vehicle exterior environment temperature and the vehicle exterior environment temperature in a preset future time period with the temperature thresholds in the preset environment threshold conditions respectively;
[0073] If the current vehicle exterior environment temperature or the vehicle exterior environment temperature in a preset future time period is less than or equal to the temperature threshold, it is determined that the environmental information meets the preset environmental threshold condition;
[0074] If the current vehicle exterior environment temperature and the vehicle exterior environment temperature in a preset future time period are both greater than the temperature threshold, it is determined that the environmental information does not meet the preset environmental threshold condition.
[0075] In this first embodiment, after using the vehicle sensor to obtain the current environmental information, the current external environmental temperature is obtained through analysis; after using the networking system to obtain the environmental information of the future time period, the external environmental temperature of the future time period is obtained through analysis; the obtained external environmental temperatures of the two time periods are compared with the temperature thresholds in the preset environmental threshold conditions; if the external environmental temperature of the current or future time period is less than the temperature threshold, it is judged that the environmental information of the vehicle meets the preset environmental threshold conditions, and the vehicle needs to enter the low-temperature antifreeze mode; if the external environmental temperatures of the current and future time periods are both greater than the temperature threshold, it is judged that the environmental information of the vehicle does not meet the preset environmental threshold conditions, and the vehicle is controlled to maintain in normal mode.
[0076] Step 102: When the environmental information meets the preset environmental threshold conditions, a low temperature antifreeze reminder is issued.
[0077] Furthermore, in the first embodiment, when the environmental information meets the preset environmental threshold condition, a low temperature antifreeze reminder is issued, which also includes:
[0078] After the low temperature antifreeze reminder is issued, if the user does not issue a command to enter the low temperature antifreeze mode, the vehicle is controlled to enter the normal mode.
[0079] In this first embodiment, when the vehicle's hidden door handle antifreeze control system determines that the vehicle needs to enter the low-temperature antifreeze mode at this time, the control system sends a pop-up window prompting whether to enter the low-temperature antifreeze mode command, and voice prompts whether to enter the low-temperature antifreeze mode command; the user can confirm whether to agree to the vehicle entering the low-temperature antifreeze mode by manually clicking on the large screen or voice dialogue according to his own intention. If the user agrees to enter the low-temperature antifreeze mode, the control system controls the door handle to enter the low-temperature antifreeze mode according to the received command to enter the low-temperature antifreeze mode; if the user does not agree to enter the low-temperature antifreeze mode, that is, the control system does not receive the command to enter the low-temperature antifreeze mode, the normal mode of the vehicle is maintained. When the first embodiment determines that the vehicle currently needs to enter the low-temperature trigger mode through sensors and the networking system, it first sends a low-temperature trigger mode reminder to the user, and then controls the vehicle to enter the low-temperature trigger mode after obtaining the user's authorization, which meets the diverse needs of users and improves the user experience.
[0080] Step 103: When a command from a user to enter a low-temperature antifreeze mode is received, the door handle is controlled to be unfolded, and the door handle is controlled to remain in the unfolded state.
[0081] Further, in the first embodiment, controlling the door handle to be unfolded and controlling the door handle to remain in the unfolded state is specifically as follows:
[0082] Control the door handle to unfold and collect the door handle status in real time;
[0083] When the door handle is in the unfolded state, the door handle indicator light is turned on, and the door handle is controlled to remain in the unfolded state;
[0084] When the door handle is in the folded state, the door handle is cyclically controlled to perform folding and unfolding operations;
[0085] If the door handle is still in a folded state when the maximum number of cycles is reached, a manual unfolding reminder is issued.
[0086] In this first embodiment, when the user chooses to enter the low-temperature antifreeze mode, the door handle is controlled to unfold, and the door handle is controlled to remain in the unfolded state. Specifically, to ensure that the door handle is successfully unfolded, after the door handle unfolding command is issued, the door handle state is collected in real time. If the door handle state collected is unfolded, the door handle indicator light is turned on to remind the user that the door handle is unfolded at this time. If the door handle state collected is folded, it means that the door handle has failed to unfold this time, and the door handle needs to be unfolded again. Therefore, a door handle folding command is first issued, and then a door handle unfolding command is issued to control the door handle to unfold again. After the door handle is controlled to unfold again, the door handle state is collected again to determine whether the door handle is unfolded successfully this time. If the returned door handle state is still in the folded state, the door handle is controlled to perform the folding and unfolding operation in a cycle until the unfolded state of the door handle is collected. Among them, since the hidden door handle motor needs a large current to unfold and fold, when repeatedly driving the door handle motor to unfold and fold, in order to protect the motor, the maximum number of cycles of folding and unfolding the door handle is pre-set. If the folding and unfolding operation of the door handle has reached the maximum number of cycles and its state is still folded, in order to protect the motor, the folding and unfolding operation of the door handle is stopped, and a manual unfolding reminder is issued to remind the user to manually break the ice. When the user successfully breaks the ice and opens the door, the door handle is controlled to remain in the unfolded state.
[0087] Furthermore, in the first embodiment, the door handle status is collected in real time, specifically:
[0088] Real-time acquisition of door handle motor current;
[0089] Comparing the door handle motor current with a preset operating current;
[0090] When the door handle motor current is greater than or equal to a preset working current, determining that the current door handle state is unfolded;
[0091] When the door handle motor current is less than a preset working current, it is determined that the current door handle state is folded.
[0092] In the first embodiment, the state of the door handle can be collected through the working current of the motor. When the door handle is driven to unfold, the motor passes a working current, and the value of the working current is determined as the preset working current to determine whether the door handle is successfully unfolded. Specifically, the door handle motor current is collected in real time. When the door handle motor current is greater than or equal to the preset working current, the current door handle is in the unfolded state; when the door handle motor current is less than the preset working current, the current door handle is in the folded state.
[0093] Step 104: When the environmental information does not meet the preset environmental threshold condition, control the door handle to fold, and control the door handle to remain in the folded state.
[0094] Further, in the first embodiment, the door handle is controlled to be folded, and the door handle is controlled to remain in the folded state, specifically:
[0095] Control the folding of the door handle and collect the door handle status in real time;
[0096] When the door handle is in a folded state, the door handle indicator light is turned off, and the door handle is controlled to remain in a folded state;
[0097] When the door handle is in the unfolded state, the door handle is cyclically controlled to perform unfolding and refolding operations;
[0098] If the door handle is still in the unfolded state when the maximum number of cycles is reached, a manual folding reminder is issued.
[0099] In the first embodiment, when the vehicle is in the low-temperature antifreeze mode, the current external environment temperature and the external environment temperature in the future time period are still collected in real time through the sensor and the networking system. If the current external environment temperature and the external environment temperature in the future time period are both greater than the preset temperature threshold, it is determined that it is not necessary to enter the low-temperature antifreeze mode at this time, then the door handle is controlled to be folded, and the door handle is controlled to remain in the folded state to reduce the energy consumption of the vehicle. Specifically, when the door handle is controlled to be folded, in order to ensure that the door handle is successfully folded, after the door handle folding command is issued, the door handle state is collected in real time. If the collected door handle state is folded, the door handle indicator light is turned off to remind the user that the door handle is folded at this time. If the collected door handle state is unfolded, it means that the door handle folding failed this time and the door handle needs to be folded again. Therefore, the door handle unfolding command is issued first, and then the door handle folding command is issued to control the door handle to fold again. After the door handle is controlled to be folded again, the door handle state is collected again to determine whether the door handle is folded successfully this time. If the returned door handle state is still unfolded, the door handle is controlled to unfold and fold again in a loop until the folded state of the door handle is collected. Among them, since the unfolding and folding of the hidden door handle motor requires a large current, when repeatedly driving the door handle motor to unfold and fold, in order to protect the motor, the maximum number of cycles of unfolding and folding the door handle is pre-set. If the unfolding and folding operation of the door handle has reached the maximum number of cycles and its state is still unfolded, in order to protect the motor, the unfolding and folding operation of the door handle is stopped, and a manual folding reminder is issued to remind the user to fold manually. When the user successfully folds the door handle, the door handle is controlled to remain in the unfolded state.
[0100] Further, in the first embodiment, when the environmental information does not meet the preset environmental threshold condition, the door handle is controlled to be folded, and the door handle is controlled to remain in the folded state, further comprising:
[0101] Determine the current vehicle status;
[0102] If the current vehicle status is driving, a voice reminder to exit the low-temperature antifreeze mode will be issued after the door handle is folded;
[0103] If the current vehicle status is locked, no voice reminder will be issued.
[0104] In this first embodiment, when it is detected that the ambient temperature outside the vehicle in the current and future time periods is greater than the temperature threshold, the door handle is controlled to fold, and a voice reminder is issued to prompt the user to exit the low-temperature antifreeze mode. In order to reduce vehicle energy consumption, the current vehicle state is determined before the voice reminder is issued. If the current vehicle state is the driving state, it means that there is a user driving the vehicle in the vehicle at this time, and a voice reminder is issued after the door handle is folded to prompt the user that the vehicle has exited the low-temperature antifreeze mode at this time. If the current vehicle state is the locked state, it means that the vehicle is not driving at this time and there may be no user in the vehicle. At this time, in order to save vehicle energy consumption, no voice reminder may be issued.
[0105] Step 105: When unlocking information or travel reservation information is received, the door handle is controlled to be unfolded, and the door handle is controlled to remain in the unfolded state.
[0106] In the first embodiment, when the vehicle is in driving or locked state, if the ambient temperature outside the vehicle in the current and future time periods is greater than the temperature threshold, the vehicle is controlled to enter the normal mode. When the vehicle is in the normal mode, if the vehicle needs to be unlocked or the user makes a travel reservation, the door handle is controlled to be unfolded and the door handle is controlled to remain unfolded. The control process of the door handle unfolding at this time is consistent with the control process of entering the low temperature antifreeze mode.

[0108] The acquisition module 201 is used to collect environmental information within a preset time in real time, and compare the environmental information with a preset environmental threshold condition;
[0109] The low temperature reminder module 202 is used to issue a low temperature antifreeze reminder when the environmental information meets the preset environmental threshold conditions;
[0110] The first deployment control module 203 is used for controlling the door handle to be deployed and to maintain the deployed state when receiving a command to enter the low temperature antifreeze mode issued by the user;
[0111] The folding control module 204 is used to control the door handle to fold and keep the door handle in a folded state when the environmental information does not meet the preset environmental threshold condition;

[0113] Furthermore, in the second embodiment, the environmental information within a preset time is collected in real time, specifically:
[0114] Use optical rainfall sensors to collect current rainfall information in real time;
[0115] Use temperature sensors to collect current temperature information in real time;
[0116] Using the networking system to obtain weather status information for a preset future time period;
[0117] The current rainfall information, the current temperature information and the weather status information of a preset future time period are determined as the environmental information within the preset time period.

[0122] If the current vehicle exterior environment temperature or the vehicle exterior environment temperature in a preset future time period is less than or equal to the temperature threshold, it is determined that the environmental information meets the preset environmental threshold condition;
[0123] If the current vehicle exterior environment temperature and the vehicle exterior environment temperature in a preset future time period are both greater than the temperature threshold, it is determined that the environmental information does not meet the preset environmental threshold condition.
[0124] Further, in the second embodiment, the door handle is controlled to be unfolded, and the door handle is controlled to remain in the unfolded state, specifically:
[0125] Control the door handle to unfold and collect the door handle status in real time;

[0149] In this second embodiment, based on the centralized EEA architecture of automotive electronic domain, i.e., vehicle domain controller (VDC) + regional controller (ZCUFL, ZCUFR), the vehicle domain controller can receive the temperature and other vehicle environment information, door handle status information, and network weather information sent by the networking system sent by ZCUFL and ZCUFR. The vehicle domain controller (VDC) interacts with the ICC central control screen through control commands, and the vehicle domain controller (VDC) interacts with the regional controller (ZCUFL, ZCUFR) through drive commands; the ICC central control screen and the regional controller (ZCUFL, ZCUFR) provide status feedback to the vehicle domain controller (VDC).
[0150] In the second embodiment, the zone controller ZCUFL controls the left door handle, and the zone controller ZCUFR controls the left door handle. Specifically, the zone controller ZCUFL controls the left front hidden door handle motor to unfold, the left front hidden door handle motor to fold, the left front hidden door handle indicator light, the left rear hidden door handle motor to unfold, the left rear hidden door handle motor to fold, and the left rear hidden door handle indicator light. The zone controller ZCUFR controls the right front hidden door handle motor to unfold, the right front hidden door handle motor to fold, the right front hidden door handle indicator light, the right rear hidden door handle motor to unfold, the right rear hidden door handle motor to fold, and the right rear hidden door handle indicator light.
[0151] In this second embodiment, the user can choose whether to enter the low-temperature antifreeze mode by touching the switch on the ICC central control screen or through voice interaction with the voice recognition module. If the user chooses to enter the low-temperature antifreeze mode, the VDC sends a door handle expansion drive command to ZCUFL and ZCUFR. ZCUFL and ZCUFR execute the door handle expansion drive command and control the door handle to remain in the expanded state when the car is driving or locked. When the VDC comprehensively determines that the current outdoor ambient temperature has exceeded the preset temperature (for example, 0°C) for 1 hour, the VDC sends four door handle folding drive commands to ZVUFL and ZCUFR, and sends a voice broadcast to the large screen to exit the low-temperature antifreeze mode control command (only sent when driving, not sent when the car is locked), ZCUFL and ZCUFR drive the motor to fold, and the voice module broadcasts.
[0152] In this second embodiment, if the user chooses not to enter the low-temperature antifreeze mode, the normal mode will be automatically entered. When the user unlocks the vehicle outside, or remotely turns on the air conditioning and heating based on the SOA service to make a travel reservation, the door handle SOA service will be automatically called to unfold the door handles (only triggered when the current environmental characteristic information is less than the preset freezing condition). VDC sends four door handle unfolding drive instructions to ZCUFL and ZCUFR. ZCUFL and ZCUFR execute the four door handle unfolding drive instructions and determine whether the door handle motor is blocked by the motor working current, and then determine whether the door handle is successfully unfolded, and feedback the door handle status to VDC. VDC determines whether the four door handles are successfully unfolded. If there are door handles that have not been unfolded, the corresponding door handle folding is sent to ZCUFL / ZCUFR once. The drive command for re-expanding, ZCUFL / ZCUFR executes the corresponding drive command and feedbacks the door handle status, VDC determines again whether it is successfully unfolded, if there are still door handles that have not been successfully unfolded, then send the corresponding door handle folded once again, and then unfold the drive command, wherein the maximum cycle is set for the re-expanding drive command. At this time, for example, if there are still door handles that have not been successfully unfolded after 3 unfoldings and 2 foldings, then VDC stops sending the drive command and sends the door handle unfolding failure information to the mobile phone APP; at this time, the user needs to manually break the ice to open the car door. After manually breaking the ice and successfully opening the car door, the door handle remains in the unfolded state and will not be recovered during driving unless the user manually selects the door handle to be folded through the mobile phone or large screen. When the door handle is unfolded, ZCUFL / ZCUFR feedbacks the door handle status to VDC. VDC sends the corresponding door handle indicator light on / off drive command to ZCUFL / ZCUFR based on the received door handle status information. After receiving the command, ZCUFL / ZCUFR drives the door handle indicator light to light up / off through hard wire, and feedbacks the door handle indicator light status to VDC.
[0153] In this second embodiment, the hidden door handle antifreeze control system has a motor thermal protection function. Since the hidden door handle motor needs a large current to unfold and fold, when repeatedly driving the door handle motor to unfold and fold, in order to protect the motor, the door handle motor can be set to perform a maximum of 3 unfolding and 2 folding drive commands (i.e. unfold, fold, unfold, fold, unfold). When the unfolding and folding operation of the door handle motor reaches the maximum number of cycles, the cyclic operation is stopped to protect the motor.
[0154] In the second embodiment, the process of executing the hidden door handle antifreeze control method using the hidden door handle antifreeze control system is as follows:
[0155] When the vehicle is in motion or locked, ZCUFL collects ambient temperature and rainfall information through the optical rain sensor and ambient temperature sensor, and sends it to VDC through CAN signals;
[0156] VDC obtains the weather characteristics of the current and future period through the networking system;
[0157] VDC determines whether it is necessary to enter the hidden door handle low temperature antifreeze mode based on the received outside temperature and light rainfall information sent by ZCUFL, combined with network weather information, and whether the current environmental characteristic information is less than the preset environmental threshold conditions;
[0158] If the VDC determines that the current environmental characteristic information is less than the preset environmental threshold condition and needs to enter the hidden door handle low temperature antifreeze mode, the VDC sends a pop-up window prompting whether to enter the door handle low temperature antifreeze mode command and a voice prompting whether to enter the door handle low temperature antifreeze mode command to the central control screen through the CAN signal;
[0159] After the large screen receives the above control command, a pop-up window will be displayed to remind you whether to enter the door handle low temperature antifreeze mode; and the voice module will prompt you whether to enter the door handle low temperature antifreeze mode;
[0160] The user manually clicks the large screen or speaks to decide whether to enter the door handle low temperature antifreeze mode according to his / her intention;
[0161] The central control screen recognizes whether the user's touch screen information or voice information enters the door handle low temperature antifreeze mode, and feeds back the user's intention to the VDC through the CAN signal;
[0162] VDC combines the above information to determine whether the current user is willing to enter the door handle low temperature antifreeze mode.
[0163] 1. If the user chooses to enter the door handle low temperature antifreeze mode: VDC sends a drive command to ZCUFL and ZCUFR to unfold the four door handles and keep them unfolded;
[0164] After receiving the door handle deployment drive command, ZCUFL and ZCUFR drive the door handle motor through hard wire to perform the deployment action and feedback the door handle status to VDC;
[0165] VDC determines whether the current door handle is unfolded. If it is unfolded successfully, it sends a door handle indicator light-up drive command to ZCUFL and ZCUFR through CAN signal; if it is not unfolded successfully, it sends a four-door handle unfolding and maintaining unfolding state drive command to ZCUFL and ZCUFR.
[0166] After receiving the door handle indicator light-up drive command, ZCUFL and ZCUFR drive the door handle indicator light up through the hard line and feedback the door handle indicator light status to VDC;
[0167] Keep the door handle in the extended state while driving or locking the car until VDC determines that the current ambient temperature outside the car has been > 0℃ for more than 1 hour and there will be no rain, snow or freezing in the future, then exit the low temperature antifreeze mode and enter the normal mode;
[0168] VDC sends four door handle folding drive commands to ZCUFL and ZCUFR;
[0169] VDC sends a voice prompt to the large screen to exit the low temperature antifreeze mode (the voice prompt is only in the driving state, not in the locked state);
[0170] After receiving the voice reminder command, the large screen will broadcast the reminder through the voice module;
[0171] After receiving the door handle folding drive command, ZCUFL and ZCUFR drive the door handle motor to fold through hard wire and feedback the door handle status;
[0172] VDC determines whether the current door handle is folded. If the door handle is folded successfully, VDC sends the corresponding door handle indicator light off drive command to ZCUFL and ZCUFR; if the door handle is not folded successfully, VDC sends four door handle folding drive commands to ZCUFL and ZCUFR again. After receiving the door handle indicator light off drive command, ZCUFL and ZCUFR drive the door handle indicator light to turn off through hard wire and feedback the door handle indicator light status to VDC.
[0173] 2. If the user chooses not to enter the door handle low temperature antifreeze mode, or if the VDC determines that the current environmental characteristic information is greater than the preset environmental threshold condition and does not need to enter the hidden door handle low temperature antifreeze mode, the door handle normal mode is entered. When in the door handle normal mode:
[0174] If the vehicle needs to be unlocked, VDC sends a door handle deployment drive command to ZCUFL and ZCUFR;
[0175] If the vehicle is in the defense state and the outside temperature is low, the user's mobile phone APP makes an appointment for travel through the SOA service to remotely turn on the air conditioning and heating. Then, through the SOMEIP protocol, VDC automatically calls the door handle SOA service to control the door handle. VDC sends a door handle deployment drive command to ZCUFL and ZCUFR, and remotely turns on the air conditioner. At this time, the door handle deployment operation can save time for the user's travel;
[0176] After receiving the door handle deployment drive command, ZCUFL and ZCUFR drive the door handle motor to deploy through hard wire;
[0177] ZCUFL and ZCUFR determine whether the door handle is deployed successfully: by collecting the working current of the door handle motor and comparing it with the preset current threshold (where the preset current threshold can be set according to the motor characteristics), determine whether the motor is blocked, and feedback the four door handle states to VDC;
[0178] VDC determines whether there is a door handle that has not been unfolded according to the door handle status: if there is a door handle that has not been unfolded, it sends a drive command to the corresponding ZCUFL / ZCUFR to fold the corresponding door handle once and then unfold it; and sends a drive command to light up the corresponding door handle indicator to the ZCUFL / ZCUFR corresponding to the unfolded door handle;
[0179] After receiving the corresponding door handle drive command, ZCUFL / ZCUFR drives the door handle motor through hard wire to fold and unfold, and then feedback the door handle status again;
[0180] VDC determines whether there are any door handles that have not been unfolded according to the door handle status: if there are any door handles that have not been unfolded, it sends a drive command to the corresponding ZCUFL / ZCUFR to fold the corresponding door handle once and then unfold it; and sends a drive command to light up the corresponding door handle indicator to the ZCUFL / ZCUFR corresponding to the unfolded door handle;
[0181] After receiving the corresponding door handle drive command, ZCUFL / ZCUFR drives the door handle motor through hard wire to fold and unfold, and then feedback the door handle status again;
[0182] VDC determines whether the door handle is still not deployed based on the door handle status: if the door handle is still not deployed, the motor protection is performed: the door handle will not be deployed anymore, and manual ice breaking operation is required. VDC will no longer issue the deployment drive command; a door handle deployment failure prompt will be sent to the APP;
[0183] When the car door is successfully opened by manually breaking the ice, the door handle remains unfolded and will not be retracted during driving unless the user manually chooses to fold the door handle through a mobile phone or large screen.
[0184] In this second embodiment, the hidden door handle antifreeze control system is based on the EEA architecture, that is, the vehicle domain controller (VDC) + regional controller (ZCUFL, ZCUFR). Control decisions are made in the vehicle domain controller, and the SOA service can be performed by interacting with the mobile phone APP through the networking system. The antifreeze control logic is judged by the vehicle domain controller, and the door handle motor expansion / folding drive command and the door handle indicator light on / off drive command are issued to ZCUFL and ZCUFR, and pop-up prompts and voice prompts are sent to the central control screen. ZCUFL collects current temperature information, door handle indicator light status, and door handle expansion / folding status through hard-wired light and rain sensors and ambient temperature sensors, and feeds them back to VDC, and executes door handle motor drive commands and door handle indicator light drive commands through hard wires. Remote control based on Ethernet communication of SOMEIP service interacts with local control door handles based on CAN communication of signals. The two coexist, and the system meets compatibility.
[0185] In summary, the present invention provides a hidden door handle antifreeze control method, device, equipment and storage medium, which collects environmental information within a preset time in real time, and compares the environmental information with the preset environmental threshold conditions; when the environmental information meets the preset environmental threshold conditions, a low temperature antifreeze reminder is issued; when a command to enter the low temperature antifreeze mode issued by the user is received, the door handle is controlled to be unfolded, and the door handle is controlled to remain in the unfolded state; when the environmental information does not meet the preset environmental threshold conditions, the door handle is controlled to be folded, and the door handle is controlled to remain in the folded state; when unlocking information or travel reservation information is received, the door handle is controlled to be unfolded, and the door handle is controlled to remain in the unfolded state.
