[0023] The prior art has three defects: first, the prior art usually uses a mobile phone support to set the mobile phone beside the instrument panel and is always connected with a charging line, thereby continuously charging the mobile phone, but this charging condition will have certain influence on the driving of the driver; second, charging is performed through a wireless charger, but the wireless charger is arranged at an armrest box, the driver cannot view the mobile phone in real time and needs to reserve multiple mobile phones; and third, the mobile phone is charged through a wireless charging support, the wireless charging support is also external and needs to be powered through a connecting line and has small charging power.

[0024] Please refer to Figure 1 , Figure 1 The flow chart of the vehicle-mounted wireless charger control method provided in an embodiment of the present application is shown in Figure 1 The present application provides a vehicle-mounted wireless charger control method, which is applied to a vehicle-mounted wireless charger, the vehicle-mounted wireless charger comprises a wireless charging module, the wireless charging module is arranged in a target area, the target area represents a visible range of the driver when the driver is in a driving state, and a to-be-charged device is placed on the wireless charging module, and the method at least comprises steps S110 to S130: S110: obtaining eye movement information of the driver and a spatial charging position of the to-be-charged device.

[0025] The vehicle-mounted wireless charger comprises a wireless charging control module, a rotating actuator and a wireless charging module, as shown in Figure 2 The first setting mode is that the vehicle-mounted wireless charger is arranged at the right side of the instrument panel and the left side of the center control display, thereby facilitating the driver of the main driving position to view the navigation information; the second setting mode is that the vehicle-mounted wireless charger is arranged at the left side of the instrument panel, and in the driving state of the driver, the driver can see the to-be-charged device on the vehicle-mounted wireless charger in the two setting modes, and the to-be-charged device does not need to be removed from the vehicle-mounted wireless charger. The center control display is connected with the wireless charging control module through CAN bus communication (Controller Area Network). As shown in Figure 3 The center control display comprises a display screen and a screen control module, the eye movement information of the driver is obtained through an in-vehicle camera, the camera feeds back the eye movement information to the screen control module, and the screen control module provides the wireless charging control module with the eye movement information.

[0026] The spatial charging position of the device to be charged is collected by the wireless charging control module, the spatial position information of the vehicle-mounted wireless charger in the vehicle is determined according to the position of the vehicle-mounted wireless charger, and the spatial charging position of the device to be charged for wireless charging is determined by the wireless charging module. For example, a certain point of the main driving position is taken as the origin of the first spatial position coordinate system, the coordinates of the lower left corner of the vehicle-mounted wireless charger relative to the first spatial position coordinate system are (0.4 m, 0.6 m, 0.6 m), the unit is meter, the first value in the coordinates is the value in the x-axis direction, the second value in the coordinates is the value in the y direction, and the third value in the coordinates is the value in the z direction. The bottom of the wireless charging module is taken as the origin of the second spatial position coordinate system, and the coordinates of the center of the device to be charged relative to the second spatial position coordinate system are (5 cm, 4 cm, 6 cm), the unit is centimeter, the two coordinate positions are fused to determine the spatial charging position of the device to be charged; the spatial charging position can also be directly determined according to the spatial coordinate system in the vehicle.

[0027] It should be noted that the power supply harness of the vehicle-mounted wireless charger is built-in in the vehicle, as shown in Figure 4 The clamping mechanism 410 is arranged on the wireless charging module, and is used for clamping the device to be charged to prevent the device to be charged from falling during charging. The device to be charged can be a mobile phone, a smart watch or the like.

[0028] It should be noted that when the device to be charged is placed on the vehicle-mounted wireless charger, there is a certain angle between the screen of the device to be charged and the line of sight of the driver in the driving state, and the driver's view angle of the screen of the device to be charged is not good, so it is necessary to adjust the spatial charging position of the wireless charging module in the vehicle-mounted wireless charger, so that the screen of the device to be charged coincides with the line of sight of the driver, and the driver can obtain the navigation information he wants to know.

[0029] S120: determining a dynamic spatial offset according to the spatial charging position and the eye movement information, wherein the dynamic spatial offset represents the offset angle between the observation line of sight of the driver and the device to be charged.

[0030] In detail, the determination of the dynamic spatial offset comprises: determining the target spatial range of the wireless charging module based on the eye movement information and a preset visual transmission expression; and determining the dynamic spatial offset through the target spatial range and the spatial charging position. Specifically, as shown in Figure 3 The screen control module transmits the eye movement information to the wireless charging control module, the wireless charging control module inputs the eye movement information into the preset visual transmission expression to calculate the target spatial range of the wireless charging module under the eye movement information; and the wireless charging control module subtracts the target spatial range from the spatial position information fed back by the wireless charging module to obtain the dynamic spatial offset.

[0031] S130: generate a rotation adjustment instruction according to the dynamic spatial offset, so as to adjust the spatial orientation of the device to be charged through the rotation adjustment instruction, so that the screen of the device to be charged is in the visual range.

[0032] In detail, the rotation adjustment instruction includes a first control instruction and a second control instruction; generating a rotation adjustment instruction according to the dynamic spatial offset, so as to adjust the spatial orientation of the device to be charged through the rotation adjustment instruction, includes: when the dynamic spatial offset is greater than the preset visual deviation threshold, generating a first control instruction, driving the wireless charging module to rotate in the direction of reducing the dynamic spatial offset, so that the wireless charging module rotates to the target spatial range; when the dynamic spatial offset is less than or equal to the preset visual deviation threshold, obtaining a second control instruction, and adjusting the wireless charging module by a preset angle based on the second control instruction, so that the wireless charging module rotates to the optimal spatial position, wherein the optimal spatial position represents that the driver's driving line of sight is directly opposite the screen area of the device to be charged. Specifically, the preset visual deviation threshold is (2cm, 1cm, 1cm), the preset visual deviation threshold is a spatial coordinate value, and the unit is centimeter; the dynamic visual deviation is (3cm, 2cm, 1cm), at this time, the dynamic visual deviation is greater than the preset visual deviation threshold, a first control instruction is generated according to the rotation control adjustment instruction, and the wireless charging module is controlled by the first control instruction to adjust the rotation angle and the inclination angle, thereby reducing the dynamic spatial offset. Because there are individual differences in the way the driver views the device to be charged, after adjustment, the dynamic visual deviation changes to (2cm, 0.9cm, 1cm), and when the dynamic spatial offset is less than or equal to the preset visual deviation threshold, a second control instruction input by the user through the display screen is obtained, as shown in FIG. 8, the second control instruction is input to the wireless charging control module through the display screen and the screen control module, and the spatial position of the wireless charging module is fine-tuned through the second control instruction, so that the screen of the device to be charged is located in the visual range of the driver. In the driving process, the device to be charged is located at the optimal spatial position, and there is no need to deliberately view the navigation information. Figure 3

[0033] In order to prolong the service life of the device to be charged, the control method further comprises: obtaining the charging parameter of the device to be charged through the wireless charging control module, and sending the vehicle navigation information to the wireless charging control module through the screen control module, so that the wireless charging control module adjusts the charging power of the vehicle-mounted wireless charger according to the charging parameter and the vehicle navigation information.

[0034] ​In detail, the method further comprises: obtaining vehicle navigation information and charging parameters of the to-be-charged device; determining a standard charging duration according to a current power, a real-time consumption power and a standard charging power in the charging parameters; when the standard charging duration is less than an estimated driving duration in the vehicle navigation information, optimizing the charging power of the to-be-charged device to a preset charging power, so that the charging duration of the to-be-charged device approaches the estimated driving duration; wherein the preset charging power does not exceed the maximum charging power of the to-be-charged device. Specifically, the device model of the to-be-charged device is recognized by the wireless charging control module, and the remaining current power, the maximum charging power, the real-time consumption power of the to-be-charged device in the navigation process, the vehicle navigation information provided by the display screen, and the estimated driving duration of the vehicle to the destination in the vehicle navigation information are obtained by the screen control module provided to the wireless charging control module. The wireless charging control module calculates the process consumption power of the to-be-charged device in the driving process according to the real-time consumption power and the estimated driving duration. The wireless charging control module determines the required charging power according to the full power, the current power and the process consumption power. The wireless charging control module calculates the standard charging duration according to the required charging power and the standard charging power. When the standard charging duration is less than the estimated driving duration, the wireless charging control module generates a power adjustment instruction, sets the preset charging power as the charging power of the to-be-charged device according to the power adjustment instruction, and reduces the charging power of the to-be-charged device. Through the preset charging power, the difference between the charging duration of the to-be-charged device and the estimated driving duration is within the preset charging time threshold, for example, the time difference between the charging duration and the estimated charging duration is controlled within ten minutes. It is tried to ensure that the to-be-charged device is always in a charging state during the driving of the vehicle, to protect the charging battery of the to-be-charged device, and to have no impact on the user's later use of the mobile phone. During the driving of the vehicle, the user will not use the mobile phone, which indirectly improves the safety of the driving of the vehicle.

[0035] In more detail, the obtaining method of the preset charging power comprises: obtaining a plurality of power setting values; determining the optimal charging power according to the current power, the real-time power consumption and the estimated driving time; determining the preset charging power by using the priority decision based on the plurality of power setting values, the standard charging power and the optimal charging power; wherein the priority decision is determined based on the user setting preference, the charging efficiency and the estimated driving time. Specifically, the obtaining method of the preset charging power comprises: the user inputs a plurality of power setting values through the display screen, and transmits them to the wireless charging control module through the screen control module; the wireless charging control module determines the optimal charging power according to the current power, the real-time power consumption and the estimated driving time, and the optimal charging power makes the charging time of the device to be charged equal to the estimated driving time, i.e. the vehicle reaches the destination and the power of the device to be charged is just full. The charging power includes a plurality of preset charging powers, a standard charging power and an optimal charging power. The actual charging power includes a first actual charging power, a second actual charging power and a third actual charging power. The wireless charging control module calculates a plurality of first actual charging powers according to the plurality of power setting values and the estimated driving time. The wireless charging control module calculates the second actual charging power according to the standard charging power and the estimated driving time. The wireless charging control module calculates the third actual charging power according to the standard charging power and the estimated driving time. The priority is determined based on the actual charging power and the required charging power. If the user does not set the preference, the charging power corresponding to the actual charging power equal to the required charging power is taken as the first priority, the charging power corresponding to the actual charging power within the range of 95% to 100% of the required charging power is taken as the second priority, the charging power corresponding to the actual charging power exceeding the required charging power is taken as the third priority, and the charging power corresponding to the actual charging power within the range of 80% to 95% of the required charging power is taken as the fourth priority. In the case where the user does not intervene in the charging power setting, the power corresponding to the first priority is taken as the preset charging power. If there is no charging power of the first priority in the plurality of power setting values and the standard charging power, the charging power of the second priority is taken as the preset charging power. If there is no charging power of the first priority and the second priority, the charging power of the third priority is taken as the preset charging power. If there is only the charging power of the fourth priority, the charging power of the fourth priority is taken as the preset charging power. If the user sets other power as the first priority according to his own needs, the corresponding charging power can be set as the preset charging power. The priority can be multiple, and the number of priorities can be increased according to the actual situation, which is not limited here.

[0036] It should be noted that the user can turn on or off the wireless charging function of the vehicle-mounted wireless charger on the central control display, and send the on or off instruction to the wireless charging control module through the screen control module through the display screen, so as to realize the function of turning on or off the wireless charging.

[0037] In detail, the method further comprises: obtaining the spatial charging position of the wireless charging module and the current charging power of the device to be charged after the preset time interval of adjusting the charging power; generating position fault information if the spatial charging position deviates from the optimal spatial position; generating power fault information if the current charging power deviates from the preset charging power, and adjusting the charging power of the wireless charging module to the standard charging power. Specifically, after the preset time interval of adjusting the charging power, for example, after 5 seconds of adjusting the charging power, the wireless charging control module has completed sending the information of spatial position adjustment to the rotating actuator, the current spatial charging position and the current charging power of the device to be charged are obtained, if the current spatial charging position is not on the optimal spatial position, the wireless charging module generates position fault information, and the position fault information is fed back to the display screen to remind the user of the failure of position adjustment. If the current charging power is not equal to the preset charging power, the device to be charged generates power fault information according to the current charging power, the power fault information is fed back to the display screen to remind the user of the failure of power adjustment, and the charging power of the wireless charging module is adjusted to the standard charging power.
