The invention discloses a method and device for suppressing the energy consumption of the battery of an electronic key. The method includes: determining a relative position of a vehicle and an associated electronic key; determining a relative distance between the vehicle and the associated electronic key; setting the maximum distance at which the vehicle and the associated electronic key can be normally controlled, and according to a relationship between the relative distance and the maximum distance between the vehicle and the associated electronic key, classifying the relative position relationship between the vehicle and the associated electronic key into a first position relationship, a second position relationship and a third position relationship; when the relative position relationship between the vehicle and the associated electronic key is the first position relationship or the third position relationship, setting the control mode of the electronic key to an energy-efficient suppression mode; when the relative position relationship between the vehicle and the associated electronic key is the second position relationship, setting the control mode of the electronic key to anormal control mode. The method solves the problem that the battery of the electronic key consumes too much power and has a low power utilization rate.
Description
technical field [0001] The present application relates to the field of intelligent control, in particular to a battery energy consumption suppression method for electronic keys, and to a battery energy consumption suppression device for electronic keys. Background technique [0002] With the development of automobile intelligence, intelligent functions such as unlocking of vehicle door locks can be performed without using mechanical keys. In the smart key system, when a user carrying an electronic key approaches the vehicle, the vehicle-mounted device compares the ID code of the electronic key, and according to the result of the code correspondence, the ID code of the electronic key is authenticated by the vehicle, even if the mechanical key is not inserted into the vehicle door lock, Up unlocking of the vehicle door lock is also possible. During authentication, the electronic key receives the request signal sent by the vehicle-mounted device. After receiving the request si...
