Abstract

A lock control apparatus for a vehicle includes anchors to receive a signal transmitted from a terminal; a communication module to communicate using controller area network (CAN) communication; a detector installed on a door to input a detection signal; and a processor to receive the signal transmitted from the terminal from at least one of the anchors through the communication module, calculate a position of the terminal based on the signal transmitted from the terminal, determine whether to unlock the door in response to the position of the terminal and the detection signal, and control an engine to start. The processor controls the anchors to enter a sleep mode in response to waiting times of the anchors and resets the anchors to release the sleep mode and controls the anchors to enter a waiting mode in response to the number of anchors transmitting the signal from the terminal.

First claim

What is claimed is:

1. A method of ranging for receiving a signal in anchors,
waiting for a signal from an initiator,
wherein the signal is generated for each block at a period;
ranging an anchor between the initiator and the anchor based on a ranging block, wherein the ranging block is divided into ranging rounds; and
determining whether or not the signal is received based on a time grid for a ranging session for the ranging block,
wherein block timing of the ranging block is established based on a network.

2. The method of claim 1 ,
wherein at least one of the anchors is connected to the initiator based on the time grid.

3. The method of claim 1 ,
wherein a state for at least one of the anchors is determined based on the time grid, and
wherein the state includes a sleep mode and a waiting mode.

4. A device of ranging for receiving a signal in as anchors, comprising:
a processor; and
a memory configured to store control data for controlling the processor,
wherein the processor is configured to:
wait for a signal from an initiator, wherein the signal is generated for each block at a period; and
range an anchor between the initiator and the anchor based on a ranging block, wherein the ranging block is divided into ranging rounds; and
determine whether or not the signal is received based on a time grid for a ranging session for the ranging block,
wherein block timing of the ranging block is established based on a network.

5. The device of claim 4 ,
wherein at least one of the anchors is connected to the initiator based on the time grid.

6. The device of claim 4 ,
wherein a state for at least one of the anchors is determined based on the time grid, and
wherein the state includes a sleep mode and a waiting mode.
