Vehicle key positioning method, and apparatus and storage medium

A method comprising:

• after a vehicle completes a communication connection with a key of the vehicle, determining respective distances between a plurality of positioning anchor points of the vehicle and the key, based on respective ranging signals between the plurality of positioning anchor points and the key;
• when one reference anchor point is determined from the plurality of positioning anchor points based on the respective distances between the plurality of positioning anchor points and the key, correcting a distance between a positioning anchor point adjacent to the one reference anchor point and the key to obtain a corrected distance;
• wherein the reference anchor point indicates that a transmission mode of a ranging signal between the reference anchor point and the key is line-of-sight wireless transmission (LOS);
• performing positioning calculation on a distance between the one reference anchor point and the key and the corrected distance to obtain final position information of the key relative to the vehicle;
• and
• executing a preset action corresponding to both the final position information of the key relative to the vehicle and a control instruction issued by the key.

A control apparatus, comprising:

• a processor and a memory;
• wherein,
• the memory stores executable instructions executable by the processor;
• and
• the processor executes the executable instructions stored in the memory, so that the processor is enabled to:
• after a vehicle completes a communication connection with a key of the vehicle, determine respective distances between a plurality of positioning anchor points of the vehicle and the key, based on respective ranging signals between the plurality of positioning anchor points and the key;
• when one reference anchor point is determined from the plurality of positioning anchor points based on the respective distances between the plurality of positioning anchor points and the key, correct a distance between a positioning anchor point adjacent to the one reference anchor point and the key to obtain a corrected distance;
• wherein the reference anchor point indicates that a transmission mode of a ranging signal between the reference anchor point and the key is line-of-sight wireless transmission (LOS);
• perform positioning calculation on a distance between the one reference anchor point and the key and the corrected distance to obtain final position information of the key relative to the vehicle;
• and
• execute a preset action corresponding to both the final position information of the key relative to the vehicle and a control instruction issued by the key.
