Driver assistance apparatus for vehicle and vehicle having the same

A vehicle comprising:

• a driver assistance apparatus comprising:
• a camera configured to acquire an image outside of the vehicle;
• and
• a first processor configured to
• detect an object in the image,
• determine whether a collision between the vehicle and the object is expected, and
• provide a height control signal for a suspension of the vehicle to adjust a height of an expected impacted portion of the vehicle;
• and
• a suspension apparatus comprising:
• an interface unit configured to receive the height control signal;
• and
• a second processor configured to control a height of the suspension according to the height control signal,
• wherein the object includes a following vehicle positioned behind the driver's vehicle,
• wherein the first processor is configured to:
• provide the height control signal for lowering a rear wheel suspension of the driver's vehicle when sudden braking is performed when a collision between the driver's vehicle and the following vehicle is expected,
• provide a control signal for performing full-braking after a collision between the driver's vehicle and the following vehicle, and
• provide a height control signal for lowering a front wheel suspension of the driver's vehicle when a collision between the driver's vehicle and a preceding vehicle positioned in front of the driver's vehicle is expected after a collision between the driver's vehicle and the following vehicle, and
• wherein the first processor is further configured to:
• determine an overturning situation based on whether rotation of the object about an overall-length direction greater than or equal to a reference value is sensed in the image, and
• provide, based on the determination of the overturning situation, the height control signal for raising left wheel suspensions or right wheel suspensions.

A method of controlling a suspension of a vehicle, the method comprising:

• acquiring, by at least one camera, an image outside of a driver's vehicle, the image being a vehicle front view image, a vehicle rear view image or a vehicle side view image;
• detecting, by at least one processor, an object in the image, wherein the object includes a following vehicle positioned behind the driver's vehicle;
• determining, by the processor, whether a collision between the driver's vehicle and the object is expected;
• providing, by the processor, a height control signal for a suspension of the driver's vehicle to adjust a height of an expected impacted portion of the driver's vehicle;
• providing, by the processor, the height control signal for lowering a rear wheel suspension of the driver's vehicle when sudden braking is performed when a collision between the driver's vehicle and the following vehicle is expected;
• providing, by the processor, a control signal for performing full-braking after a collision between the driver's vehicle and the following vehicle;
• providing, by the processor, a height control signal for lowering a front wheel suspension of the driver's vehicle when a collision between the driver's vehicle and a preceding vehicle positioned in front of the driver's vehicle is expected after a collision between the driver's vehicle and the following vehicle;
• determining an overturning situation based on whether rotation of the object about an overall-length direction greater than or equal to a reference value is sensed in the image;
• and
• providing, based on the determination of the overturning situation, the height control signal for raising left wheel suspensions or right wheel suspensions.
