Speed controller for car using telematics and control method thereof
First Claim
1. A speed controller for a car using telematics, the speed controller comprising:
- a sensor unit to detect the speed of the car according to traveling, a distance from the car to an object in front, and an operating status of a brake pedal and an accelerator pedal;
a telematics system to output a signal to control the travel speed of the car automatically and a gear shifting signal so as to prevent a collision accident with the object in front, when the travel speed of the car and the distance from the car to the object in front exceeds a preset range of an approaching distance, in response to the signal detected by the sensor unit;
a speed regulation system to maintain the travel speed of the car within a speed limit by controlling an accelerator pedal and a brake pedal control unit, in response to the control signal outputted by the telematics system; and
an automatic transmission system to set a gear shifting level corresponding to the travel speed of the car controlled by the speed regulation system by automatically controlling a gear shifting lever control unit, in response to a gear shifting signal outputted by the telematics system.

4. A method of controlling a speed of a car using telematics, the method comprising:
-
detecting an object in front, the travel speed of the car, and an operating status of an accelerator pedal, a brake pedal, and a gear shifting lever operated by a driver, while the car is traveling; calculating the travel speed of the accelerated car and a distance from the car to the object in front using the information detected by the detecting step, when the travel speed of the car is accelerated by the driver; determining whether the distance between the accelerated car and the object in front is closer than a range of an approaching distance (current distance≧
preset distance) from the calculated travel speed and distance;decelerating the travel speed of the accelerated car to a speed limit through the selective control of an accelerator pedal control unit, a brake pedal control unit, and a gear shifting lever control unit, when the distance between the accelerated car and the object in front is getting closer than a preset range of the approaching distance, as the result of the above calculation; determining whether the distance between the car and the object in front maintains the preset range of the approaching distance (current distance<
preset distance), when the travel speed of the car is reduced to the speed limit); andperforming the determining operation repeatedly when the distance between the decelerated car and the object in front does not maintain the preset approaching distance, or returning to the calculation operation when the distance between the decelerated car and the object in front is longer than the preset approaching distance, as the result of the above determination. - View Dependent Claims (5, 6)
