Abstract
An apparatus for controlling a suspension of a vehicle includes: an illuminance sensor that measures illuminance outside the vehicle, a camera that takes an image of a road surface ahead the vehicle, and a controller that recognizes an obstacle located on the road surface based on the image of the road surface ahead the vehicle, determines a type of the obstacle depending on the measured illuminance outside the vehicle, and controls a damping force of the suspension based on control information corresponding to the type of the obstacle when the vehicle passes over the obstacle.
Claims18
An apparatus for controlling a suspension of a vehicle, the apparatus comprising:
- an illuminance sensor configured to measure illuminance outside the vehicle;
- a camera configured to take an image of a road surface ahead the vehicle;
- and
- a controller configured to:
- recognize an obstacle located on the road surface based on the image of the road surface ahead the vehicle,
- determine a type of the obstacle based on the measured illuminance, and
- control a damping force of the suspension based on control information corresponding to the determined type of the obstacle when the vehicle passes over the obstacle,
- wherein the controller is further configured to divide the measured illuminance into a plurality of sections and differently set criteria for determining the type of the obstacle in the respective sections, and
- wherein:
- the plurality of sections includes a first section with a first measured illuminance value and a second section with a second measured illuminance value that is less than the first measured illuminance value,
- the controller is configured to set a first number of the criteria for the first section and a second number of the criterial for the second section, and
- the first number of criteria is greater than the second number of criteria.
A method for controlling suspension of a vehicle, the method comprising:
- measuring, by an illuminance sensor, illuminance outside the vehicle;
- taking, by a camera, an image of a road surface ahead the vehicle;
- recognizing, by a controller, an obstacle located on the road surface based on the image of the road surface ahead the vehicle;
- determining, by the controller, a type of the obstacle based on the measured illuminance;
- and
- controlling, by the controller, a damping force of the suspension based on control information corresponding to the determined type of the obstacle when the vehicle passes over the obstacle,
- wherein determining the type of the obstacle includes:
- dividing the measured illuminance into a plurality of sections;
- differently setting criteria for determining the type of the obstacle in the respective sections, wherein the plurality of sections includes a first section with a first measured illuminance value and a second section with a second measured illuminance value that is less than the first measured illuminance value;
- and
- setting a first number of the criteria for the first section and a second number of the criterial for the second section, wherein the first number of criteria is greater than the second number of criteria.
