It should be noted that the set step size is determined according to the software execution cycle calibration of the controller, for example, the set step size is 0.1 s. The set time is determined according to the custom calibration such as the charging interval, for example, the set time is 0.5 s.
Step 309: the bus system between the wireless charging base and the MP5 is controlled to enter a sleep state.
Step 310: step 303 is performed by MP5 prompting the bus system to be in a sleep state.
According to the charging control method based on the vehicle-mounted wireless charging device, before whether the metal sliding block on the inverted trapezoidal sliding groove abuts against the metal limit stop is detected in real time, if the whole vehicle is electrified, self-detection is carried out, and after the self-detection is qualified, the MP5 prompts that charging is to be carried out; whether a metal sliding block on the inverted trapezoidal sliding groove abuts against a metal limit stop is detected in real time, if the metal sliding block and the metal limit stop do not abut against each other after the set time for charging is prompted, a bus system between a wireless charging base and the MP5 is controlled to enter a dormant state, and the MP5 prompts that the bus system is in the dormant state. Thereby effectively reducing the bus load.
In summary, the vehicle-mounted wireless charging device and the control method provided by the embodiment of the invention place the charging coil into the wireless charging base as a whole, and when the charging coil needs to be used, the charging coil can be pulled out and turned over to be opened, and then the mobile terminal is placed on the wireless charging base to be charged, at this time, the mobile terminal vertically placed on the upper portion of the center console can be charged, and the simple use requirements of a driver, such as navigation, bluetooth call and the like, can also be met. Inside can filling in the module main part with the folding base that charges of wireless when not needing to charge, the console resumes original state this moment, has kept the integrality of interior trim, and the device structural style has both promoted the convenience of use that wireless charges, avoids other debris to the influence of charging performance, does not influence the clean and tidy of driving table face yet, has eliminated the potential safety hazard of traveling. The control and the information display of the device are transmitted through the bus, the communication with the MP5 is realized, the working state and the fault type are displayed, an external power supply is not needed in the control mode, the safety of the electric system of the whole vehicle is ensured, the display state and the fault are clearer by utilizing the MP5, and the device has good operability.
The foregoing detailed description of the embodiments of the present invention has been presented for purposes of illustration and description, and is intended to be exemplary only of the systems and methods for understanding the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
