Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

1 is a block diagram briefly showing a configuration of an object detecting apparatus for a vehicle according to the present invention.

As shown in FIG. 1, an object detecting apparatus for a vehicle according to the present invention includes a detector 100, a calculator 200, a controller 300, a storage 400, and an output 500. .

The detector 100 detects a moving object approaching to the left and right rear of the vehicle and a fixed object located at the side of the vehicle.

For example, when the sensing unit 100 detects a moving object approaching the left rear of the vehicle, the distance between the moving object and the left rear of the vehicle continuously changes as the moving object approaches the left rear of the vehicle. ) Keeps track of changing distances.

That is, when the sensing unit 100 detects the moving object, the detection result continuously changes according to the movement of the moving object.

However, when the sensing unit 100 detects the fixed object existing on the right side of the vehicle, the distance between the fixed object and the right side of the vehicle is constant, and thus the sensing result detected by the sensing unit 100 is constant.

In this case, the sensing unit 100 may be various other sensors capable of detecting a motion or a position, that is, a distance, of an object such as an ultrasonic sensor, an optical sensor, and a motion sensor.

In addition, the detection unit 100 starts the detection when the driver or the passenger wants to get off, and this getting off point is various cases, such as when turning off the engine, releasing the seat belt, and grasping the handle to open the door. Can be considered

For example, when the driver or the passengers hold the handle to open the door, when the driver or the passenger catches the handle, power is applied to the present invention so that the sensing unit 100 is a moving object or a fixed object. Start detection for.

The calculation unit 200 calculates the distance variation between the left and right rear of the vehicle and the moving object or the distance between the side of the vehicle and the fixed object according to the detection result of the detection unit 100.

For example, when the operation unit 200 receives a detection result of the moving object approaching the rear left of the vehicle, that is, a changing detection result from the detection unit 100, the operation unit 200 may move the left side of the moving object and the vehicle based on the received detection result. Calculate the distance change between the rear.

That is, the calculation unit 200 calculates a distance between the object and the right rear side of the vehicle based on the detection result output from the detection unit 100 according to the movement of the moving object, and receives the detection result from the detection unit 100. The distance variation amount (for example, the moving speed of the moving object) of the moving object is calculated based on the interval and the calculated distance.

In addition, when the calculation unit 200 receives a detection result for the fixed object existing on the right side of the vehicle, that is, a predetermined detection result from the detection unit 100, the distance between the fixed object and the right side of the vehicle is based on the received detection result. Calculate

Then, the calculation unit 200 compares the calculated distance with the door openable range of the preset vehicle stored in the storage unit 400 to be described later.

The control unit 300 determines whether the moving object or the fixed object is based on the result calculated by the operation unit 200, and accordingly locks or releases the door 600 of the vehicle or outputs a guide message.

For example, the controller 300 determines whether an object detected by the sensing unit 100 is a moving object or a fixed object according to a result of calculating the calculation unit 200 in a constant, that is, a fixed distance or a variable distance.

As a result of the determination, in the case of the moving object, the controller 300 determines whether the moving object enters into a preset danger range stored in the storage unit 400 to be described later.

As a result, when the moving object enters the corresponding range, the control unit 300 controls to lock the vehicle door 600, the vehicle door 600 because the moving object has entered the dangerous range when the driver or passengers get off the vehicle. Controls the output unit 500 to be described later to output a guide message for the lock setting.

As a result of the determination, in the case of the fixed object, the controller 300 determines whether the fixed object exists within a preset door openable range of the vehicle according to the comparison result of the operation unit 200.

As a result of the determination, when there is a fixed object within the corresponding range, the controller 300 outputs a warning guide message regarding whether the vehicle door 600 collides with the fixed object when the driver or the occupant's door 600 is opened. The output unit 500 is controlled.

The storage unit 400 stores a dangerous range for approaching a moving object, a door openable range of the vehicle when the driver or a passenger gets off, and a guide message format output from the output unit.

The output unit 500 outputs a guide message according to the position of the fixed object when the vehicle door 600 is locked or the driver or occupant opens the vehicle door 600 according to the approach of the moving object.

For example, when the vehicle door 600 is locked when the moving object enters the dangerous range, the output unit 500 sets the lock in the door 600 in the preset message format, and thus the door 600 is locked. Should be displayed. "

In addition, when the fixed object is present within the door openable range of the vehicle, the output unit 500, when opening the door 600 of the driver or the occupant, in the form of a message set for the door 600, "with the fixed object" Be careful when the door 600 is opened because it may cause a collision ".

The output unit 500 is preferably a display screen (not shown) and a speaker (not shown) of the audio-visual navigation system (AVN).

2 is a flowchart illustrating a method for detecting a vehicle object according to the present invention.

As shown in FIG. 2, the controller 300 determines whether a signal for detecting a moving or fixed object is received (S200).

As a result of the determination, if the detected signal is not received, the controller 300 continuously checks whether the detected signal is received.

However, when the determination result is received, the control unit 300 receives a calculation result of the distance variation between the left and right rear of the vehicle and the moving object or the distance between the side of the vehicle and the fixed object according to the received detection signal. (S210).

Then, the controller 300 determines whether the detected object is a moving object based on the received calculation result (S220).

As a result of the determination, in the case of the moving object, the controller 300 determines whether the moving object has entered a preset danger range (S230).

As a result of the determination, if not entered, the control unit 300 returns to step S200 to check whether a signal for detecting a moving or fixed object is received.

However, if the determination result, the controller 300 locks the vehicle door 600, and controls to output a guide message (S240).

In operation S220, when it is determined that the moving object is not a moving object, the controller 300 determines whether the fixed object exists within a vehicle door openable range (S250).

As a result of the determination, if it does not exist, the control unit 300 returns to step S200 to check whether a signal for detecting a moving or fixed object is received.

However, as a result of the determination, when present, the controller 300 controls to output a warning guide message for the fixed object when the vehicle door 600 is opened (S260).

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.
