Abstract
The present disclosure relates to an apparatus for assisting driving of a host vehicle including: a camera mounted to the host vehicle and having a field of view outside of the host vehicle, the camera configured to obtain front image data; and a controller configured to process the front image data, obtain collision time with a surrounding vehicle and weather information based on the image data, and control a braking device provided in the vehicle to start braking at a first braking time point based on the collision time and weather information.
Claims14
An apparatus for assisting driving of a host vehicle, the apparatus comprising:
- a camera mounted to the host vehicle and having a field of view outside of the host vehicle, the camera configured to obtain front image data;
- and
- a controller configured to:
- process the front image data, and
- obtain collision time with a surrounding host vehicle and weather information based on the image data,
- estimate a road friction coefficient based on the weather information,
- determine whether a collision with surrounding host vehicle is avoidable by changing a driving direction of the host vehicle,
- based determining that the collision with the surrounding host vehicle is unavoidable, control a braking device provided in the host vehicle to start braking at a first braking time point determined based on the collision time and the road friction coefficient.
A method for assisting driving of a host vehicle, the method comprising:
- obtaining front image data by a camera mounted to the host vehicle and having a field of view outside of the host vehicle;
- processing the front image data
- estimating a road friction coefficient based on the weather information;
- obtaining collision time with a surrounding host vehicle and weather information based on the processed image data;
- determining whether a collision with surrounding host vehicle is avoidable by changing a driving direction of the host vehicle;
- based determining that the collision with the surrounding host vehicle is unavoidable, controlling a braking device provided in the host vehicle to start braking at a first braking time point determined based on the collision time and the road friction coefficient.
A system for assisting driving of a host vehicle, the system comprising:
- a camera mounted to the host vehicle and having a field of view outside of the host vehicle, the camera configured to obtain front image data;
- a transceiver configured to communicate with a host vehicle to Everything (V2X) communication base station to receive, from the base station, information related to driving the host vehicle according to weather;
- and
- a controller configured to:
- process the front image data, and
- obtain collision time with a surrounding host vehicle and weather information based on the information received from the base station and the image data, and
- determining whether a collision with surrounding host vehicle is avoidable by changing a driving direction of the host vehicle;
- based determining that the collision with the surrounding host vehicle is unavoidable, control a braking device provided in the host vehicle to start braking at a first braking time point determined based on the collision time and a road friction coefficient.
