Abstract
A vehicle collision avoidance system and method. The vehicle collision avoidance system includes an input unit configured to receive driving information of a host vehicle and driving information of a rear vehicle, a memory configured to store a program that calculates a collision risk level using the driving information of the host vehicle and the driving information of the rear vehicle, and a processor configured to execute the program, wherein the processor performs control to display visual information about the risk of collision upon a right or left lane change based on the collision risk level.
Claims9
A vehicle collision avoidance system comprising:
- an input unit configured to receive driving information of a host vehicle and driving information of a rear vehicle;
- a memory configured to store a program that generates a collision risk level based on calculating a crash probability using the driving information of the host vehicle and the driving information of the rear vehicle, wherein the crash probability is calculated based on calculating a cumulative probability in a distribution of a braking input to the host vehicle up to a critical deceleration of the rear vehicle;
- and
- a processor configured to execute the program,
- wherein the processor performs control to display visual information about a risk of collision upon a right or left lane change based on the collision risk level;
- wherein the processor sets a plurality of mean and variance models of a driver deceleration distribution model into a preset number of sets, and adjusts a sensitivity of a collision alarm calculation based on a model selected by the driver from among the preset number of sets.
A vehicle collision avoidance method comprising operations of:
- (a) receiving driving information of a host vehicle;
- (b) receiving driving information of a rear vehicle;
- (c) generating a collision risk level based on calculating a crash probability between the host vehicle and the rear vehicle and providing a warning about a risk of collision expected upon a left or right lane change based on the collision risk level, wherein the crash probability is calculated based on calculating a cumulative probability in a distribution of a braking input to the host vehicle up to a critical deceleration of the rear vehicle;
- setting a plurality of mean and variance models of a driver deceleration distribution model into a preset number of sets;
- and
- adjusting a sensitivity of a collision alarm calculation based on a model selected by the driver from among the preset number of sets.
