Abstract

A mounting type Bluetooth unit is provided, which can lengthen the life span of a battery. The mounting type Bluetooth unit is fixedly installed in the interior of a vehicle and is provided with a casing body that packages a circuit board having a controller with control logic for performing Bluetooth communication with a Bluetooth device of a portable phone. The controller further includes a human body sensor as a control switch of operation logic. Also, the controller further includes a logic for sensing a driver'"'"'s getting into/out of the vehicle in accordance with existence/nonexistence of a sensing signal of the human body sensor and controlling the operation of the Bluetooth unit in a sleep/awake or power-on/off state to cancel pairing with the Bluetooth device in a non-use state.

Claims

1. A mounting type Bluetooth unit fixedly installed in the interior of a vehicle, the mounting type Bluetooth unit comprising:

a casing body; and

a circuit board packaged in the casing body, the circuit board having a controller,

wherein the controller comprises;

a communication control logic for performing Bluetooth communication with a Bluetooth device of a portable phone;

a human body sensor functioning as a control switch of an operation logic; and

an operation control logic for sensing driver'"'"'s getting into/out of the vehicle in accordance with the existence/nonexistence of a sensing signal of the human body sensor and controlling the operation of the Bluetooth unit into a sleep/awake or power-on/off state to cancel pairing with the Bluetooth device in a non-use state.

2. The mounting type Bluetooth unit according to claim 1, wherein the operation control logic of the controller executes the steps in which:

the human body sensor that is in a continuous sensing state senses the interior of the vehicle;

if the driver gets out of the vehicle and the human body sensor of the Bluetooth unit senses no body temperature and non-movement of the driver to provide no output signal, the Bluetooth unit is in a sleep state in which its operation is deactivated or in a power-off state;

if the driver gets into the vehicle, the human body sensor senses a riding of the driver on the vehicle, an output signal from the human body sensor is transferred to the controller, and the controller awakens the Bluetooth unit to start its operation or triggers the power-on of the Bluetooth unit;

the controller of the Bluetooth unit attempts a connection with a surrounding Bluetooth device of a portable phone and keeps a use state of the connected Bluetooth device;

if the driver gets out of the vehicle and the human body sensor provides no output signal due to the absence of the driver in the vehicle, the connection with the Bluetooth device of the portable phone is cancelled and the use state is switched to the sleep state or the power-off state; and

if the human body sensor senses the driver'"'"'s getting in the vehicle, the Bluetooth connection state is maintained.

3. The mounting type Bluetooth unit according to claim 2, wherein the controller further comprises a logic that performs an entrance into the sleep state or a shifting to the power-off state after a predetermined time elapses.

4. The mounting type Bluetooth unit according to claim 1, wherein the human body sensor comprises dual compensated sensing elements that sense the body temperature and the movement of the human body.

5. The mounting type Bluetooth unit according to claim 4, wherein the human body sensor is a PIR (Pyroelectric Infrared Radial) sensor.
