Cruise control apparatus and control method thereof

Abstract

Disclosed is a cruise control apparatus and a cruise control method. The method includes traveling a vehicle at a speed input by a driver, receiving road information from a navigation device, confirming whether or not deceleration information is present in the road information, confirming a speed corresponding to the deceleration information if the deceleration information is present, and controlling a speed of the vehicle to the confirmed speed if the confirmed speed is greater than the input speed. If the vehicle speed exceeds the speed limit of a road, the vehicle speed is automatically reduced to below the speed limit, and a warning operation is performed. Thereby, probability of accidents due to speeding may be reduced, and it may be possible to make the driver obey the Road Traffic Act and to prevent imposition of fines due to speeding. Further, the vehicle speed is automatically reduced at bumps or curves, resulting in enhanced safety and driver convenience.

Description

technical field [0001] Embodiments of the present invention relate to a cruise control device for controlling a traveling speed of a vehicle and a control method thereof. Background technique [0002] Cruise control is used to drive a vehicle at a speed set by the driver while maintaining a safe distance between the vehicle and objects in front of the vehicle without the driver stepping on the accelerator pedal. [0003] More specifically, if the driver sets the cruise control mode by operating the corresponding mode setting button, and then sets the vehicle speed, the cruise control device can drive the vehicle at the speed set by the driver even if the driver does not step on the accelerator pedal, At the same time maintain a safe distance between the vehicle and objects in front of the vehicle. [0004] This cruise control mode of the cruise control device can be set based on the driver's will regardless of the external road environment and maintains the current driving ...

[0005] However, in fact, different roads have different speed limits

[0006] When a vehicle with a preset vehicle speed of 120km / h based on cruise control mode appears on a road with a speed limit of 100km / h, the driver may not realize that he / she is ignoring the fact that the road speed limit is 100km / h Driving a vehicle at a preset speed of 120km / h, thereby inadvertently breaching road traffic laws

This enables drivers to be fined for violating the speed limit when caught on speed-sensing cameras

[0007] In addition, in order to reduce speed at curves or speed bumps, even if it is inconvenient, the driver must directly apply the brakes or change the speed of the vehicle
