[0002] With the continuous development of automobile technology, people's requirements for driving comfort of automobiles are getting higher and higher. The steering wheel heating function can heat the steering wheel rim surface to a certain temperature in a short time, greatly improving the driving comfort in cold winter, and is deeply loved by the majority of users, especially users in cold regions. The principle of the steering wheel heating function is to cover a layer of bubble cotton pad with resistance wire under the rim leather. The heating effect is achieved by electrifying the resistance wire. At the same time, an NTC thermistor is placed near the bubble cotton pad. The controller reads the resistance value of the NTC thermistor to determine the heating temperature. When the target temperature is reached, the controller will power off the resistance wire.

[0043] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and do not limit the present application.
[0044] It should be noted that although the functional modules are divided in the system schematic diagram, and the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in a different order from the module division in the system or the order in the flow chart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.
[0045] Please refer to Figure 1 , Figure 1 is a step flow chart of the steering wheel heating control method.
[0046] The purpose of the present application is to realize the ease of use of the steering wheel heating control. The present steering wheel heating control method can be executed by the vehicle intelligent system, and when the vehicle intelligent system is executed, the steps realized include:
[0047] Step 1, display a steering wheel heating control interface on the central control screen of the vehicle.
[0048] Among them, the steering wheel heating control interface is provided with a temperature touch selection button and an on-off selection button.
[0049] Reference Figure 4 , Figure 4 is an interface structure schematic diagram of the steering wheel heating control interface.
[0050] The vehicle intelligent system will display a human-computer interaction interface through the central control screen of the vehicle, which is called a steering wheel heating control interface. Through the steering wheel heating control interface, the user can trigger the control of the heating of the steering wheel. In the steering wheel heating control interface, there are at least two touch buttons, which are temperature touch selection button and on-off selection button. Among them, Figure 4 , the temperature touch selection button is as shown by mark B, and the on-off selection button is as shown by mark A. The steering wheel heating control interface is as shown by mark C.
[0051] Among them, the temperature touch selection button is a linear interval trigger button, that is, the touch sensing area of the temperature touch selection button is linear. Among them, the touch sensing area of the temperature touch selection button is provided with a plurality of selectable temperature values according to the coordinate line. Moreover, the whole touch sensing area is a set temperature selection interval. In this specific embodiment, the interval is set to 25℃ to 38℃. In this temperature selection interval, the temperature selection position is set in a linear order with a step of 0.5℃.
[0052] And the on-off selection button is a region trigger button, that is, a specific region is set on the steering wheel heating control interface, and the region can be triggered by single point.
[0053] By setting the temperature touch selection button and the on-off selection button on the steering wheel heating control interface, the human-computer interaction of the user's instruction can be realized.
[0054] Step 2, according to the trigger of the user to the temperature touch selection button and / or the opening and closing selection button, determine the target temperature selected by the user, determine whether the user needs to open the steering wheel heating function; when it is determined that the user needs to open the steering wheel heating function, the current steering wheel heating function opening flag bit is set, and when it is determined that the user does not need to open the steering wheel heating function, the current steering wheel heating function opening flag bit is cleared.
[0055] When the user needs to heat the steering wheel, he can trigger the temperature touch selection button and trigger the opening and closing selection button. By triggering the temperature touch selection button and the opening and closing selection button in different combinations, the target temperature and the steering wheel heating function can be selected.
[0056] The vehicle-mounted intelligent system can realize different functions according to different trigger modes of the temperature touch selection button and the opening and closing selection button.
[0057] When the user triggers the steering wheel heating control interface, the vehicle-mounted intelligent system will obtain the trigger position of the user on the steering wheel heating control interface. The coordinates of the trigger position are used to determine whether the user triggers the temperature touch selection button or the opening and closing selection button.
[0058] The set of coordinates of the trigger response area where the temperature touch selection button is located is referred to as the first coordinate position set. The set of coordinates of the trigger response area where the opening and closing selection button is located is referred to as the second coordinate position set.
[0059] In order to determine whether the user triggers the temperature touch selection button or the opening and closing selection button, the vehicle-mounted intelligent system will match the coordinates of the trigger position with the first coordinate position set and the second coordinate position set respectively.
[0060] When it is determined that the coordinates of the trigger position belong to the first coordinate position set, it can be considered that the user triggers the temperature touch selection button. When it is determined that the coordinates of the trigger position belong to the second coordinate position set, it can be considered that the user triggers the opening and closing selection button.
[0061] In some application scenarios, the user has already opened the steering wheel heating function, and at this time, the user needs to change the heating temperature of the steering wheel. In this scenario, the user will trigger the temperature touch selection button to select the desired heating temperature.
[0062] Therefore, in this scenario, the vehicle intelligent system confirms that the user has triggered the temperature touch selection button. The vehicle intelligent system then accesses the steering wheel heating function opening flag bit to determine whether the steering wheel heating function opening flag bit is set. When the steering wheel heating function opening flag bit is set at this time, it can be considered that the user needs to open the steering wheel heating function. In order to determine the target temperature expected by the user, the vehicle intelligent system determines the target temperature selected by the user from the pre-set position calibration table through the coordinates of the trigger position, and takes the target temperature as the current target temperature.
[0063] In some application scenarios, the user does not open the steering wheel heating function, but the user triggers the temperature touch selection button. This application scenario can be considered as that the user does not have the demand to open the steering wheel heating function temporarily, but selects the expected heating temperature in advance.
[0064] Therefore, for this application scenario, the vehicle intelligent system confirms that the user has triggered the temperature touch selection button. The vehicle intelligent system accesses the steering wheel heating function opening flag bit, and determines that the user does not need to open the steering wheel heating function when it is determined that the steering wheel heating function opening flag bit is not set. The vehicle intelligent system determines the target temperature selected by the user from the pre-set position calibration table through the coordinates of the trigger position, and takes the target temperature as the current target temperature.
[0065] In some application scenarios, the user needs to open the steering wheel heating function. At this time, the user triggers the opening and closing selection button.
[0066] For this application scenario, the vehicle intelligent system determines that the user triggers the opening and closing selection button. The vehicle intelligent system then accesses the steering wheel heating function opening flag bit to determine whether the steering wheel heating function opening flag bit is set. When it is determined that the steering wheel heating function opening flag bit is not set, it can be considered that the user has not opened the steering wheel heating function before, and needs to open the steering wheel heating function at present. At this time, the vehicle intelligent system sets the current steering wheel heating function opening flag bit.
[0067] In some application scenarios, the user needs to close the steering wheel heating function, and at this time, the user also triggers the opening and closing selection button.
[0068] For this application scenario, the vehicle-mounted intelligent system determines that the user triggers the opening and closing selection button. Then access the current steering wheel heating function opening flag. When the access determines that the steering wheel heating function opening flag has been set, it can be considered that the user indeed needs to close the steering wheel heating function. At this time, the vehicle-mounted intelligent system will clear the current steering wheel heating function opening flag to provide marking information for subsequent closing of the steering wheel heating function.
[0069] Step 3, periodically monitor the current steering wheel heating function opening flag and the vehicle power-off condition;
[0070] In order to determine the current situation of the steering wheel, the vehicle-mounted intelligent system will periodically monitor the steering wheel heating function opening flag, and also monitor the vehicle power-off condition. So as to respond to the user's expected control of the steering wheel in time.
[0071] Step 4, when it is monitored that the steering wheel heating function opening flag is set and the vehicle is not powered off, the current target temperature is transmitted to the steering wheel heating controller. The steering wheel heating controller dynamically heats the steering wheel according to the target temperature, so that the temperature of the steering wheel is in the target temperature.
[0072] The vehicle-mounted intelligent system monitors the steering wheel heating function opening flag and the vehicle power-off condition. When it is determined that the steering wheel heating function opening flag is set, it can be explained that the user expects to open the steering wheel heating function. And at this time, the vehicle is not powered off, which means that the steering wheel heating function can be opened at this time. Therefore, the vehicle-mounted intelligent system will transmit the target temperature to the steering wheel heating controller. Request the steering wheel heating controller to dynamically heat the steering wheel. Realize the purpose of making the temperature of the steering wheel in the target temperature.
[0073] Step 5, when it is monitored that the steering wheel heating function opening flag is cleared or the vehicle is powered off, the steering wheel heating controller stops the heating work of the steering wheel.
[0074] Of course, when the vehicle-mounted intelligent system monitors that the steering wheel heating function opening flag is cleared or the vehicle is powered off. It can be explained that the user needs to close the steering wheel heating function at this time, or the vehicle does not have the condition of steering wheel heating at this time. Therefore, the vehicle-mounted intelligent system will request the steering wheel heating controller to stop the heating work of the steering wheel through the steering wheel heating controller. The steering wheel heating controller stops the heating work of the steering wheel, which specifically includes cutting off the power supply of the heating pad resistance wire of the steering wheel.
[0075] The application shows a steering wheel heating control interface, and acquires user's expected heating control of the steering wheel through the steering wheel heating control interface. Moreover, the steering wheel heating temperature selection is more flexible in the form of temperature interval. The application improves the user's ease of use of the steering wheel heating control.
[0076] As for how to deliver the target temperature to the steering wheel heating controller, in some further embodiments, the vehicle-mounted intelligent system can request the entertainment host controller of the vehicle to deliver the target temperature to the steering wheel heating controller through the CAN bus.
[0077] After the steering wheel heating controller receives the target temperature, the steering wheel can be dynamically heated. In some further embodiments, the steering wheel heating controller dynamically heats the steering wheel according to the target temperature specifically includes:
[0078] Step 101, the steering wheel heating controller controls the heating pad resistance wire of the steering wheel to be powered on;
[0079] Step 102, the steering wheel heating controller acquires the surface temperature of the steering wheel in real time;
[0080] Step 103, when the surface temperature is less than the target temperature, the steering wheel heating controller continues to control the heating pad resistance wire of the steering wheel to be powered on, and returns to step 102; when the surface temperature is greater than or equal to the target temperature, the steering wheel controller controls the heating pad resistance wire of the steering wheel to stop being powered on, and returns to step 102.
[0081] Reference Figure 2 , Figure 2 is a structural schematic diagram of a steering wheel heating control device;
[0082] On the other hand, a steering wheel heating control device is provided, which includes a processor and a memory for storing a computer readable program. When the computer readable program is executed by the processor, the processor realizes the steering wheel heating control method as described in any of the above embodiments.

[0084] Reference Figure 3 , Figure 3 is a schematic diagram of a system structure of a steering wheel heating control system.
[0085] In another aspect, a steering wheel heating control system is provided, comprising: a display module, a determination module, a monitoring module, and a control module.
[0086] The display module is configured to display a steering wheel heating control interface on a central control screen of a vehicle, wherein the steering wheel heating control interface is provided with a temperature touch selection button and an on-off selection button.
[0087] The display module displays a human-computer interaction interface, referred to as a steering wheel heating control interface, on the central control screen of the vehicle. Through the steering wheel heating control interface, the user can trigger the heating of the steering wheel. In the steering wheel heating control interface, there are at least two touch buttons, namely a temperature touch selection button and an on-off selection button.
[0088] The temperature touch selection button is a linear interval trigger button, that is, the touch sensing area of the temperature touch selection button is linear. The touch sensing area of the temperature touch selection button is provided with a plurality of selectable temperature values according to coordinates. Moreover, the entire touch sensing area is a set temperature selection interval. In the embodiment, the set interval is 25-38°C. In the temperature selection interval, the temperature selection positions are set in a linear order with a step of 0.5°C.
[0089] The on-off selection button is a region trigger button, that is, a specific region is provided on the steering wheel heating control interface, and the region can be triggered by a single point.
[0090] The temperature touch selection button and the on-off selection button provided on the steering wheel heating control interface can realize the human-computer interaction of the user's instructions.
[0091] The determination module is configured to determine the target temperature selected by the user according to the trigger of the temperature touch selection button and / or the on-off selection button, and determine whether the user needs to start the steering wheel heating function.
[0092] When it is determined that the user needs to start the steering wheel heating function, the current steering wheel heating function start flag bit is set, and when it is determined that the user does not need to start the steering wheel heating function, the current steering wheel heating function start flag bit is cleared.
[0093] When the user needs the steering wheel heating, the user can trigger the temperature touch selection button and the on-off selection button. Different trigger combinations of the temperature touch selection button and the on-off selection button can be used to select the target temperature and start the steering wheel heating function.
[0094] The determination module can realize different functions according to different trigger modes of the temperature touch selection button and the on-off selection button.
[0095] When the user triggers the steering wheel heating control interface, the vehicle-mounted intelligent system obtains the trigger position of the user on the steering wheel heating control interface. The coordinates of the trigger position are used to determine whether the user triggers the temperature touch selection button or the on-off selection button.
[0096] The trigger response area coordinates set of the temperature touch selection button is referred to as a first coordinate position set, and the trigger response area coordinates set of the on-off selection button is referred to as a second coordinate position set.
[0097] In order to determine whether the user triggers the temperature touch selection button or the on-off selection button, the in-vehicle intelligent system matches the coordinate of the trigger position with the first coordinate position set and the second coordinate position set respectively.
[0098] When it is determined that the coordinate of the trigger position belongs to the first coordinate position set, it can be considered that the user triggers the temperature touch selection button. When it is determined that the coordinate of the trigger position belongs to the second coordinate position set, it can be considered that the user triggers the on-off selection button.
[0099] In some application scenarios, the user has already turned on the steering wheel heating function, and at this time, the user needs to change the heating temperature of the steering wheel. In this scenario, the user will select the desired heating temperature by triggering the temperature touch selection button.
[0100] Therefore, in this scenario, the determination module confirms that the user has triggered the temperature touch selection button. The determination module then accesses the steering wheel heating function on marker bit to determine whether the steering wheel heating function on marker bit is set. When the steering wheel heating function on marker bit is set at this time, it can be considered that the user needs to turn on the steering wheel heating function. In order to determine the target temperature desired by the user, the determination module determines the target temperature selected by the user from the pre-set position calibration table through the coordinate of the trigger position, and takes the target temperature as the current target temperature.
[0101] In some application scenarios, the user does not turn on the steering wheel heating function, but triggers the temperature touch selection button. This application scenario can be considered as that the user does not have the demand to turn on the steering wheel heating function temporarily, but selects the desired heating temperature in advance.
[0102] Therefore, for this application scenario, the determination module confirms that the user has triggered the temperature touch selection button. The determination module accesses the steering wheel heating function on marker bit, and when it is determined that the steering wheel heating function on marker bit is not set, it is considered that the user does not need to turn on the steering wheel heating function. The in-vehicle intelligent system determines the target temperature selected by the user from the pre-set position calibration table according to the coordinate of the trigger position, and takes the target temperature as the current target temperature.
[0103] In some application scenarios, the user needs to turn on the steering wheel heating function. At this time, the user will trigger the on-off selection button.
[0104] For this application scenario, the determining module determines that the user triggers the on-off selection button. Then the determining module accesses the current steering wheel heating function on-off flag. When it is determined that the steering wheel heating function on-off flag is set, it can be considered that the user actually needs to turn off the steering wheel heating function. At this time, the determining module clears the current steering wheel heating function on-off flag to provide marking information for subsequent steering wheel heating function off.
[0105] In some application scenarios, the user needs to turn off the steering wheel heating function. At this time, the user will also trigger the on-off selection button.
[0106] For this application scenario, the determining module determines that the user triggers the on-off selection button. Then the determining module accesses the current steering wheel heating function on-off flag. When it is determined that the steering wheel heating function on-off flag is set, it can be considered that the user actually needs to turn off the steering wheel heating function. At this time, the determining module clears the current steering wheel heating function on-off flag to provide marking information for subsequent steering wheel heating function off.
[0107] The monitoring module is configured to periodically monitor the current steering wheel heating function on-off flag and the vehicle power-off condition.
[0108] In order to determine the current situation of the steering wheel, the monitoring module will periodically monitor the steering wheel heating function on-off flag, and also monitor the vehicle power-off condition. Thus, the user's expected control of the steering wheel can be responded to in a timely manner.
[0109] The control module is configured to: when it is monitored that the steering wheel heating function on-off flag is set and the vehicle is not powered off, the current target temperature is transmitted to the steering wheel heating controller, and the steering wheel heating controller dynamically heats the steering wheel according to the target temperature, so that the temperature of the steering wheel is in the target temperature; when it is monitored that the steering wheel heating function on-off flag is cleared or the vehicle is powered off, the steering wheel heating controller stops the heating operation of the steering wheel.
[0110] The control module can determine that the steering wheel heating function on-off flag is set through monitoring the steering wheel heating function on-off flag and the vehicle power-off condition. It can be considered that the user expects to turn on the steering wheel heating function. Moreover, at this time, the vehicle is not powered off, which means that the steering wheel heating function can be turned on at this time. Therefore, the control module will transmit the target temperature to the steering wheel heating controller to request the steering wheel heating controller to dynamically heat the steering wheel, so that the temperature of the steering wheel is in the target temperature.
[0111] Of course, when the control module monitors that the steering wheel heating function opening flag bit is cleared or the vehicle is powered off, it can be indicated that the user needs to turn off the steering wheel heating function or the vehicle does not have the condition of steering wheel heating at this time. Therefore, the vehicle-mounted intelligent system requests the steering wheel heating controller to stop the heating operation of the steering wheel. The steering wheel heating controller stopping the heating operation of the steering wheel specifically includes: cutting off the power supply of the heating pad resistance wire of the steering wheel.
