Abstract

A speed bump detection apparatus may include a sensor for measuring driving data of a vehicle during forward driving of the vehicle, and a controller for monitoring generation of external disturbances of front wheels and rear wheels and determining presence of a speed bump, in which the controller determines that the speed bump is present when |L−S|≰K, when an external disturbance is generated in a rear wheel, where L is a wheel base of the vehicle, S is a movement distance of the vehicle after an external disturbance is generated in a front wheel, and K is a preset threshold value.

Description

technical field [0001] The invention relates to a speed bump detection device, a navigation data updating device and a navigation data updating method using the device. More particularly, the present invention relates to a technique for recognizing an environment of a road through an Electronic Stability Control (ESC) device to update navigation data in real time and thus improve a driving environment of a vehicle based on the updated navigation data. Background technique [0002] While the vehicle is driving, it is possible to recognize the environment of the road by utilizing the data collected in the vehicle. The ESC device may serve as a control unit of the vehicle, and the ESC device may recognize the environment of a road through data collected by the vehicle on the speed of wheels of the vehicle, the speed of the vehicle, and position information. [0003] In addition, using the navigation system, the setting of the damping force of the suspension can be changed when...
