Embodiment Construction

[0028] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0029] The inventors of the present application found that the current keyless entry and one-key start systems usually use PEPS to drive low-frequency antennas for key detection, and the PEPS low-frequency operating frequency is 125kHz±2.5kHz. WPC adopts Qi standard, A6 three-coil, working frequency: 110kHz~205kHz, depending on the location of the mobile phone, the resulting working frequency is also different. Different frequencies are produced by different cell phone locations.

[0030] When charging, WPC seeks the resonance point to obtain the maximum charging efficiency, so each time the mobile phone is placed in a different position, the frequency of WPC charging is also different. If the WPC charging frequency is exactly 125kHz, the interference to the PEPS system is the greatest, and the interference...

Abstract

The invention provides a vehicle control method and system and a vehicle. The control method comprises that a PEPS system detects whether a preset trigger condition for activating a key-seeking condition is satisfied; and if so, the PEPS system sends a stop signal to a charging module to turn off the charging module; wherein the PEPS is connected to the charging module through a signal line, and the charging module stops charging after receiving the stop signal. The method of the present invention can avoid the low-frequency interference of a WPC on the PEPS in order that the PEPS can find a key easily.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle control method, a control system and a vehicle. Background technique [0002] With the continuous improvement of people's requirements for vehicle comfort and convenience, the keyless entry and exit function of cars has been popularized from the high-end market to the low-end market, and its application is becoming more and more extensive. This entry and exit mode brings users A new experience of comfort and convenience. At the same time, in order to further improve the user experience perception, a mobile phone wireless charging configuration is added in the car. Wireless charging of mobile phones is generally arranged on the sub-dashboard, and car owners can place the mobile phone at the charging place for charging at any time, eliminating the cumbersome connection of data lines. This method of charging mobile phones brings a new and convenient experience to custome...
