Embodiment Construction

[0022] Hereinafter, further multiple embodiments will be described with reference to the drawings. In the drawings, the same symbols indicate the same or similar parts.

[0023] The wireless communication device according to the embodiment will be described with reference to the drawings. figure 1 It is a block diagram showing a schematic configuration of a vehicle that performs intermittent reception. figure 2 It is a block diagram showing the configuration of a wireless communication device that performs discontinuous reception. In the present embodiment, the intermittent reception period is shortened to reduce current consumption based on the result of signal detection by the RF unit of the control device of the wireless communication device installed in the vehicle.

[0024] like figure 1 As shown, the vehicle 200 is provided with a control unit 11, an RF unit 12, an engine 31, an air conditioner 32, lamps 33a to 33f, doors 34a to 34d, a mirror 35a, and a mirror 35b. ...

Abstract

According to an embodiment, the control unit produces a first control signal and a second control signal. The first control signal is to set an intermittent reception period. The second control signal is to control a start-up of reception of a wireless signal. When the reception processing is implemented during the intermittent reception period, the RF unit stops in accordance with an instruction of the control unit after the reception processing signal is outputted, the intermittent reception period is awoken. When the reception processing exceeds the intermittent reception period, the RF unit continues the reception, and stops in accordance with the instruction of the control unit after the reception processing signal is outputted.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority based on prior Japanese Patent Application No. 2012-061937 filed on Mar. 19, 2012, the entire contents of which are hereby incorporated by reference. technical field [0003] The embodiments described herein relate to wireless communication devices. Background technique [0004] Intermittent operation in which the operation is stopped when there is no input / output signal and set to a standby mode to reduce current consumption is often used in wireless communication devices. In the case of intermittent reception (intermittent reception), the RF unit or the microcomputer operates during the intermittent reception period, and the microcomputer is set to a sleep mode while waiting for a signal. [0005] In a wireless communication device compatible with keyless entry (Keyless Entry) that transmits a wireless communication signal from a portable device, the waiting time is lo...
