Abstract
A method and device for controlling brake system based on preceding vehicle recognition are disclosed. The device comprising: a data collecting unit configured to collect front data and rear data of a preceding vehicle, a driving trajectory extracting unit configured to extract a driving trajectory of a lane in which the vehicle is traveling, a preceding vehicle analysis unit configured to determine driving information of the preceding vehicle, a preceding vehicle determining unit configured to determine intervention of the preceding vehicle or deviation of the preceding vehicle with respect to the driving trajectory, and a control unit configured to control the brake system.
Claims16
A device for controlling a brake system of a vehicle, the device comprising:
- a data collecting unit configured to collect front data and rear data of a preceding vehicle located in front of the vehicle using at least one camera and at least one optical sensor included in a front of the vehicle;
- a driving trajectory extracting unit configured to extract a driving trajectory of a lane in which the vehicle is traveling using the at least one camera and the at least one optical sensor;
- a preceding vehicle analysis unit configured to determine driving information of the preceding vehicle based on image data collected by the at least one camera, the driving information of the preceding vehicle including an overall length of the preceding vehicle;
- a preceding vehicle determining unit configured to determine whether the preceding vehicle intervenes in the driving trajectory or deviates from the driving trajectory;
- and
- a control unit configured to control the brake system of the vehicle based on a determination made by the preceding vehicle determining unit
- wherein the control unit increases a braking force input to at least one wheel of the vehicle to avoid a collision between the vehicle and the preceding vehicle when the overall length of the preceding vehicle is greater than a preset value.
A method for controlling a brake system of a vehicle based on preceding vehicle recognition, the method comprising:
- collecting front data and rear data of a preceding vehicle located in front of the vehicle using at least one camera and at least one optical sensor included in a front of the vehicle;
- extracting a driving trajectory of a lane in which the vehicle is traveling using the at least one camera and the at least one optical sensor;
- determining driving information of the preceding vehicle based on image data collected by the at least one camera, the driving information of the preceding vehicle including an overall length of the preceding vehicle;
- determining whether the preceding vehicle intervenes in the driving trajectory or deviates from the driving trajectory using the driving information on the preceding vehicle;
- and
- controlling the brake system of the vehicle based on whether the preceding vehicle intervenes in or deviates from the driving trajectory,
- wherein:
- the controlling includes
- increasing a braking force input to at least one wheel of the vehicle to avoid a collision between the vehicle and the preceding vehicle when the overall length of the preceding vehicle is greater than a preset value.
