DMC, infotainment domain controller, infotainment domain controller.
CLM, climate Module, air conditioning control unit.
Fig. 2 shows an overall block diagram of the vehicle-mounted wireless charging system according to the embodiment of the present invention. In fig. 2, the CWC (wireless charging module for mobile phone) senses the mobile phone through an internal mobile phone detection mechanism under the condition that the operation is started. And feeding back the charging state of the mobile phone through the CAN signal.
The CWC (wireless charging module of the mobile phone) receives a vehicle speed signal sent by an ESP node on the CAN network. After the CWC receives the vehicle speed signal, the CWC is used for carrying out fan power dynamic compensation by an internal vehicle speed segmentation strategy.
And when receiving the charging state signal sent by the CWC, the DMC (information entertainment controller) synchronously combines other state signals of the whole vehicle, such as an environment external temperature signal and a room temperature signal sent by the CLM, so as to carry out scene mode judgment. And after judging that the CWC mobile phone rapid cooling mode is met, sending out a CWC mobile phone rapid cooling mode signal through a DMC (information entertainment controller) through a CAN network.
The DMC (domain controller) can make some special linkage modes based on the whole vehicle, such as an air purification mode, can close the window, and open the air conditioner to start the internal circulation. Such as the fast cooling mode we currently envisage. When the air conditioner control unit detects that the temperature in the vehicle is high and rapid cooling is required, a request of a rapid cooling mode is sent through a CAN signal, and after receiving the signal, the DMC triggers a vehicle association mode signal, such as closing a vehicle door and window. Meanwhile, the air conditioner triggers a rapid cooling and refrigerating mode, a compressor is started, the air quantity is maximum, and the temperature is minimum. So as to achieve the purpose of reducing the ambient temperature.
The DMC (information entertainment controller) needs to accept the function definition of the whole car with the CLM (air conditioner control unit), and the function state change of the mobile phone rapid cooling mode linkage is well regulated in advance. Examples: the mobile phone rapid cooling mode is linked with a blowing mode that the air conditioning state is adjusted to be fully cold and the air quantity is more than 5.
In order to achieve a better cooling effect, the following matching is suggested to be synchronously carried out on a whole vehicle arrangement scheme of a CWC (wireless charging board for mobile phones).
Recommended placement position a: the proposal is arranged at the falling point of the wind direction of the blowing face mode of the air outlet of the whole vehicle air conditioner, so that the heat of the mobile phone can be taken away by the cold air of the air conditioner under the condition of the cooling and refrigerating mode of the air conditioner in summer. Through data investigation and verification, the mobile phones on the market all have battery protection mechanisms at present. When the temperature of the mobile phone rises to the threshold range, the mobile phone end reduces the charging power (the common practice is to switch to a trickle charging mode, which is equivalent to a state when the electric quantity of the mobile phone is 99%).
B non-recommended position: the position where the air outlet of the air conditioner in the central control area cannot be blown to can not form an effective air convection section.
In the specific implementation process, CFD simulation analysis is carried out cooperatively in the whole vehicle factory arrangement and mobile phone charging module data design stage, and the CFD simulation analysis is adjusted to a proper state.
Example 1
As shown in fig. 1, the present embodiment provides a vehicle-mounted wireless charging linkage control method, which includes:
step 1: and acquiring the real-time running speed of the vehicle, the real-time temperature of the wireless charging equipment and the required power.
Step 2: when the required power of the wireless charging equipment is nonzero, the real-time temperature of the wireless charging equipment is larger than a first temperature threshold (such as 35 ℃) and smaller than a second temperature threshold (such as 65 ℃), and the starting of a self-contained radiating element (such as a fan) of the wireless charging equipment is controlled in a linkage mode.
For example: in summer (sunny days, the external temperature is more than 35 ℃, vehicles are sunned in a parking lot), the surface temperature of the interior decoration of the cabin is high, the interior decoration surface is easy to exceed 70 ℃ after history data investigation. According to a wireless charger thermal protection strategy mechanism, a charger is used for a sensor for monitoring the temperature of the upper surface, and when the acquired temperature is more than or equal to 65 ℃, the charger enters the thermal protection mechanism to stop charging.
Step 3: and determining the current operating duty ratio of the self-contained radiating element of the wireless charging equipment according to the relation between the required power and the operating duty ratio of the self-contained radiating element of the wireless charging equipment.
In an implementation, a relationship between the required power and an operating duty cycle of an onboard heat sink element of the wireless charging device is characterized by a first piecewise function.
Specifically, the required power is divided into several echelon levels in advance, and each echelon level corresponds to one duty cycle of the wireless charging device running with a heat dissipation element.
When the required power is at the lowest echelon level, the operating duty ratio of the self-contained heat dissipation element of the wireless charging device is the preset minimum duty ratio, and the wireless charging device stops after the wireless charging device is operated for a set period of time.
The wireless charging carries out fan rotation speed matching according to the required power after the handshake of the mobile phone protocol is successful, and the corresponding relation between the power echelon grade division and the duty ratio is shown in the figure 3 and the table 2.
The duty ratio is the ratio of the energization time to the total time in one pulse cycle. In the implementation process, the purpose of adjusting the rotating speed of the fan can be achieved by adjusting the corresponding output voltage.
Table 2 relationship between required power and duty cycle
| Sequence number | Power of | Duty cycle | Remarks |
| 1 | ≥30W | 70％ | |
| 2 | ≥20W | 66％ | |
| 3 | ≥10W | 63％ | |
| 4 | ≥6W | 60％ | |
| 5 | ＜6W | 55％ | Stopping after 10min of operation |
Step 4: and determining the optimal running speed section of the vehicle according to the relation between the running duty ratio of the self-carried radiating element of the wireless charging equipment and the optimal running speed section of the vehicle, and comparing the optimal running speed section with the real-time running speed of the vehicle so as to dynamically adjust the running speed of the vehicle.
In a specific implementation, the relation between the operation duty cycle of the self-contained heat dissipation element of the wireless charging device and the optimal running speed section of the vehicle is characterized by a second segmentation function.
The larger the operation duty ratio of the self-contained radiating element of the wireless charging device is, the larger the value of the optimal running speed section of the vehicle is.
The background noise NVH behaves differently in different vehicle speed contexts. And judging by collecting a vehicle speed signal sent by an EMS (energy management system) on the whole vehicle CAN network, and segmenting the vehicle speed signal.
In the present embodiment, the optimum running speed section of the vehicle is tentatively divided into 4 levels, and the vehicle speeds of the different levels are different in correspondence with the powers of the fans. For example:
vehicle speed signal:
L1:0-10KM/h；
L2:10-40KM/H；
L3:40-80M/h；
l4 is more than 80 KM/h.
It should be noted that in other embodiments, the optimal driving speed range of the vehicle may be divided into other number of levels, which will not be described in detail herein.
And in the later stage, the dynamic adjustment is carried out through the acquisition and calibration of real vehicle data. Therefore, the charging efficiency of the mobile phone can be met, and the NVH noise evaluation index defined by design can be met.
The correspondence between the optimum running speed range of the vehicle and the fan duty ratio is shown in fig. 4 and table 3.
TABLE 3 optimum speed range for vehicle and fan duty cycle relationship
In the specific implementation process, the slow speed rising requirement is as follows: slowly rise at a rate of 5%/0.5 s.
The slow-down requirement of the vehicle speed is as follows: slowly decreasing to the next rotating speed level at the speed of 5%/0.5s, and working for 3min (calibration value); when judging that the rotation speed is not reduced to the target rotation speed level, slowly reducing to the next rotation speed level at the speed of 5%/0.5s, and working for 2min (calibration value); when judging that the rotation speed is not reduced to the target rotation speed level, slowly reducing to the next rotation speed level at the speed of 5%/0.5s, reducing to the target rotation speed level, and continuously working.
When the required power of the wireless charging equipment is non-zero, the self-contained radiating element of the wireless charging equipment is started by comparing the real-time temperature of the wireless charging equipment with the preset threshold range, so that the active heat dissipation of the wireless charging equipment is realized; in order to balance the charging efficiency of the wireless charging device and the comfort of passengers, the embodiment utilizes the relation between the required power and the operation duty ratio of the self-carried heat dissipation element of the wireless charging device and the relation between the operation duty ratio of the self-carried heat dissipation element of the wireless charging device and the optimal running speed section of the vehicle, so that the current operation duty ratio of the self-carried heat dissipation element of the wireless charging device and the optimal running speed section of the vehicle matched with the current operation duty ratio of the self-carried heat dissipation element of the wireless charging device are determined, and the running speed of the vehicle is dynamically adjusted, so that the overall noise of the vehicle is reduced, and the comfort of the passengers taking the vehicle is improved.
In one or more embodiments, the on-vehicle wireless charging coordinated control method further includes: acquiring real-time temperature in a vehicle cabin; and when the real-time temperature in the vehicle cabin is greater than a third temperature threshold value, controlling the refrigeration on of the vehicle-mounted air conditioner in a linkage manner.

It should be noted that, each module in the embodiment corresponds to each step in the first embodiment one to one, and the implementation process is the same, which is not described here.
When the required power of the wireless charging equipment is non-zero, the self-contained radiating element of the wireless charging equipment is started by comparing the real-time temperature of the wireless charging equipment with the preset threshold range, so that the active heat dissipation of the wireless charging equipment is realized; in order to balance the charging efficiency of the wireless charging device and the comfort of passengers, the embodiment utilizes the relation between the required power and the operation duty ratio of the self-carried heat dissipation element of the wireless charging device and the relation between the operation duty ratio of the self-carried heat dissipation element of the wireless charging device and the optimal running speed section of the vehicle, so that the current operation duty ratio of the self-carried heat dissipation element of the wireless charging device and the optimal running speed section of the vehicle matched with the current operation duty ratio of the self-carried heat dissipation element of the wireless charging device are determined, and the running speed of the vehicle is dynamically adjusted, so that the overall noise of the vehicle is reduced, and the comfort of the passengers taking the vehicle is improved.
