Vehicle key system and control method thereof, and vehicle

Abstract

The invention discloses a control method of a vehicle key system. The control method is applied to a vehicle key. The control method comprises the steps of when the key is located in a vehicle, judging whether a low-frequency signal emitted by a vehicle controller is detected or not, wherein the low-frequency signal includes vehicle speed information; if the low-frequency signal is detected and the vehicle speed is less than or equal to a set threshold value, the key entering into a working mode; if the low-frequency signal is detected and the vehicle speed is larger than the set threshold value, the key entering into a vehicle interior low-power-consumption mode; if the low-frequency signal cannot be detected, the key entering into a first static mode; when the key is located outside thevehicle, judging whether the low-frequency signal or a press key signal is detected or not; if the low-frequency signal or the press key signal is detected, the key entering into the working mode; andif the low-frequency signal or the press key signal is not detected, the key entering into a second static mode. The key switches among the different modes under various situations so as to achieve the purpose of reducing power consumption.

Description

technical field [0001] The invention belongs to vehicle electronic communication, and in particular relates to a vehicle key system, a control method and a vehicle using the system. Background technique [0002] Currently, the electronic key is powered by a built-in battery. In order to increase user experience and facilitate portability, the electronic key is small in size. In view of the current battery technology and the space of the electronic key, the battery capacity inside the electronic key cannot be made too large. In order to improve the service life of the electronic key, reducing the power consumption of the key is a good solution. If the electronic key can only be placed in the normal working state at the moment of work, and be placed in a low power consumption state during other random states, the average power consumption of the electronic key will be greatly reduced. [0003] The electronic key wakes up from the sleep state (or low power consumption state) ...

AI Technical Summary

Problems solved by technology

The wake-up time affects the user experience. If the wake-up time is too long, or the wake-up conditions are not suitable, the user experience will be poor, causing the user the illusion that the key is unresponsive or damaged.

If the wake-up is too sensitive, it will cause frequent wake-up of the key, false wake-up, etc., and cannot better reduce the power consumption of the electronic key
