Abstract
A vehicle control system may include a controller that detects an object outside a vehicle, calculates an angle based on a ratio of a relative speed between the object and the vehicle to a speed of the vehicle, and updates a phase curve reflecting a phase distortion of an input signal based on the calculated angle.
Claims12
A vehicle control system comprising:
- a controller configured to:
- detect an object outside a vehicle;
- calculate an angle based on a ratio of a relative speed between the object and the vehicle to a speed of the vehicle;
- and
- update a phase curve reflecting a phase distortion of an input signal based on the calculated angle,
- wherein the controller is further configured to:
- in order to calculate the angle, obtain an object candidate group based on at least one of whether a distance between the object and the vehicle is less than or equal to a threshold distance, whether a cosine value of the input signal is less than a threshold value, or whether the ratio of the relative speed to the speed of the vehicle is equal to or less than a threshold value;
- calculate angle data based on the ratio of the relative speed to the speed of the vehicle with respect to the object candidate group;
- and
- filter the angle data.

A method of operating a vehicle control system, the method comprising:
- detecting an object outside a vehicle;
- calculating an angle based on a ratio of a relative speed between the object and the vehicle to a speed of the vehicle;
- and
- updating a phase curve reflecting a phase distortion of an input signal based on the calculated angle,
- wherein the calculating of the angle includes:
- obtaining an object candidate group based on at least one of whether a distance between the object and the vehicle is less than or equal to a threshold distance, whether a cosine value of the input signal is less than a threshold value, whether a power of the input signal is greater than or equal to a threshold power, or whether a ratio of the relative speed to the speed of the vehicle is equal to or less than a threshold value;
- calculating angle data based on the ratio of the relative speed to the speed of the vehicle with respect to the object candidate group;
- and
- filtering the angle data.
