Abstract

Disclosed herein is a backward control system for an automobile using telematics. The system includes: a sensor unit to sense a backward speed, presence of a backward object, and the operating state of the brake pedal and the accelerator pedal of an automobile when backward-travelling; a telematics system unit to output a control signal, when a distance between the automobile and the object is within a pre-set range in response to the signal from the sensor unit, such that the backward-travelling is automatically interrupted to thereby prevent collision with the object; and a accelerator pedal control unit and a brake pedal control unit to automatically control the operation of the accelerator pedal and the brake pedal to thereby interrupt the backward-travelling in response to the control signal outputted from the telematics system unit.

Claims

1. A backward control system for an automobile using telematics, the system comprising:

a sensor unit to sense a backward speed, presence of a backward object, and the operating state of the brake pedal and the accelerator pedal of an automobile when backward-travelling;

a telematics system unit to output a control signal, when a distance between the automobile and the object is within a predetermined range in response to the signal from the sensor unit, such that the backward-travelling is automatically interrupted to thereby prevent collision with the object; and

an accelerator pedal control unit and a brake pedal control unit for automatically controlling the operation of the accelerator pedal and the brake pedal to thereby interrupt the backward-travelling in response to the control signal outputted from the telematics system unit.

2. The system according to claim 1, wherein the sensor unit comprises a first sensor to sense the speed of automobile when backward-travelling, a second sensor to detect a distance between the backward-travelling automobile and the object, a third sensor to sense the operation state of the accelerator pedal caused by a driver, and a fourth sensor to sense the operation state of the brake pedal caused by the driver.

3. The system according to claim 1, wherein the telematics system unit comprises:

a distance setup unit for setting up an approaching distance between the backward-travelling automobile and the object;

a speed setup unit to set up a speed value with which the brake pedal is operated to stop the automobile;

a memory unit to store information set-up through the distance setup unit and the speed setup unit;

a signal receiver unit to receive a signal sensed from the sensor unit;

a brake control unit to output a control signal to operate and control the accelerator pedal control unit and the brake pedal control unit according to the approaching distance and the speed value stored in the memory unit when the signal receiver unit receives the sensing signal of the sensor unit; and

a signal output unit to output the control signal from the brake control unit to the accelerator pedal control unit and the brake pedal control unit.

4. The system according to claim 1, wherein the telematics system unit further comprises a rear view camera to photograph the rear side of the automobile.

5. A backward control method for an automobile using telematics, the method comprising:

detecting a backside object, a backward-travelling speed, and an operating state of a accelerator pedal and a brake pedal caused by a driver when backward-travelling;

calculating a distance between the object and the automobile;

determining whether the distance between the automobile and the object is within a predetermined approaching range, as the result of the calculation; and

stopping the automobile by interrupting the power of the accelerator pedal through operation control of a accelerator pedal control unit if the accelerator pedal is operated when the distance between the automobile and the object is within the predetermined approaching range, as the result of the determination.

6. The method of claim 5, further comprising:

determining whether the backward-travelling speed due to the operation of the brake pedal approaches a predetermined interruption speed value if the brake pedal is operated when the distance between the automobile and the object is within the predetermined approaching range;

stopping the automobile by forcible controlling the operating of the brake pedal through a brake pedal control unit if the backward-travelling speed due to the operation of the brake pedal does not approach a preset interruption speed value based upon the determination; and

stopping the automobile from the continuous operation of the brake pedal by the driver if the backward-travelling speed due to the operation of the brake pedal approaches a predetermined interruption speed value.
