Embodiment 1

[0055] figure 2 It is a schematic flowchart of a vehicle unlocking control method provided by an embodiment of the present invention. The vehicle is equipped with a door handle switch and a keyless entry PEPS controller, and the method is applied to the PEPS controller. Such as figure 2 As shown, the method includes the following steps:

[0056] Step S202, when the unlocking request sent by the door handle switch is obtained, the first type of internal antenna and the second type of internal antenna of the driving vehicle respectively send a first key query signal and a second key query signal; wherein, the first type of internal antenna The transmitting power of the antenna is greater than the transmitting power of the second type internal antenna.

[0057] When the user presses the door handle switch, the door handle switch collects the key signal, and when the door handle switch confirms that the key signal is valid, it will send an unlock request to the PEPS controller...

Abstract

The invention provides a vehicle unlocking and locking control method, device and system, and relates to the field of vehicle electronic control technology. The vehicle unlocking and locking control method comprises the following steps: when obtaining an unlocking and locking request sent by a door handle switch, driving a first-kind internal antenna and a second-kind internal antenna of a vehicleto send a first key query signal and a second key query signal, wherein the transmitting power of the first-kind internal antenna is greater than that of the second-kind internal antenna; receiving an authentication signal returned by an intelligent key based on the first key query signal and the second key query signal; when only the authentication signal returned based on the first key query signal is received, determining that the intelligent key is at the external part of the vehicle; and according to the authentication signal, carrying out legality authentication on the intelligent key,and executing an unlocking and locking operation corresponding to the unlocking and locking request after the authentication is passed. With adoption of the vehicle unlocking and locking control method, a PE function can be realized only by utilizing the internal antennae instead of relying on the external antennae, and the cost is reduced on the premise that the functional completeness and performance reliability are ensured.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to a vehicle unlocking control method, device and system. Background technique [0002] The keyless entry system is referred to as PEPS (Passive Entry Passive Start) system. The PEPS system is rapidly becoming the mainstream and common solution choice in the application of new automobile technology. Compared with pressing the smart key button to control the unlocking operation of the car door and starting the car through the traditional key, the PEPS system only needs to be carried by the owner according to the The smart key of the smart key card can automatically complete the unlocking and locking operation of the car door, and the owner who enters the car only needs to turn on the start switch to complete the start operation of the vehicle, without the need for the owner to hold the key to complete the start of the vehicle, thereby improving user comfort and...
