Abstract
Provided are a system and a method for drive control of front ultra-sonic sensors, which may minimize interference with another vehicle, caused by an ultra-sonic wave signal in a complex driving environment by detecting presence or absence of an obstacle in front and controlling a drive state of the front ultra-sonic sensor mounted on the front bumper of a vehicle.
Claims15
A system for control of front ultra-sonic sensors mounted on the front of a vehicle and detecting an obstacle in front of the vehicle, the system comprising:
- a sensor position analysis unit for analyzing a mounting position of each of a plurality of front ultra-sonic sensors mounted on the vehicle to classify (1) a first ultra-sonic sensor mounted to the side and (2) a second ultra-sonic sensor mounted to the center of the front of the vehicle;
- an obstacle detection unit for detecting the obstacle positioned within a predetermined distance in front of the vehicle by using input data related to the front of the vehicle in order to analyze distance information between the vehicle and the detected obstacle;
- and
- an output control unit for controlling a waveform produced by each ultra-sonic sensor classified by the sensor position analysis unit by using distance information analyzed by the obstacle detection unit.
A processor-implemented method for drive control of front ultra-sonic sensors, the method comprising steps of:
- analyzing a mounting position of each of a plurality of front ultra-sonic sensors mounted on the front of a vehicle to classify a first ultra-sonic sensor mounted on the side of the front of the vehicle and a second ultra-sonic sensor mounted on the center of the front of the vehicle;
- controlling a side-output waveform output from a corresponding ultra-sonic sensor to have a predetermined value when the sensor is classified as the first ultra-sonic sensor;
- and
- controlling a center-output waveform from a corresponding ultra-sonic sensor by analyzing distance information between the vehicle and an obstacle positioned in front of the vehicle to be within a predetermined distance determined by sensor position analysis when the sensor is the second ultra-sonic sensor.
