Autonomous emergency braking system and method for vehicle at crossroad
First Claim
1. An autonomous emergency braking (AEB) system comprising:
- a monitoring sensor configured to obtain detection information for calculating a distance between a host vehicle and a peripheral object and a relative speed of the peripheral object and transmit the information to an electronic control unit (ECU); and
the electronic control unit (ECU) configured to;
receive detection information from the monitoring sensor,determine a presence of a moving object, among peripheral objects, moving toward the host vehicle in a direction transverse to a current traveling direction of the host vehicle at crossroads during driving of the host vehicle,estimate, if the presence of the moving object is determined, a time to collision (TTC) between the host vehicle and the moving object,select the moving object as a control object using the detection information andif the TTC between the control object and the host vehicle is lower than a threshold, warn a driver of the host vehicle or perform autonomous emergency braking (AEB) of the host vehicle based on the TTC between the host vehicle and the selected control object.

Abstract
An autonomous emergency braking (AEB) system includes a vehicle dynamics sensor and an around-view monitoring (AVM) sensor. The AVM sensor detects a distance and relative speed between the host vehicle and a peripheral object, or transmits an image of a peripheral region of the host vehicle to the ECU. The ECU receives detection signals from the sensors, determines the presence or absence of a moving object approaching in a direction transverse to a traveling direction of the host vehicle at crossroads during driving of the host vehicle, selects the detected moving object as a control object using the detected moving object detection information if the presence of the approaching moving object is determined, and warns a driver of the host vehicle about a high possibility of collision with the selected control object or performs autonomous emergency braking (AEB) of the host vehicle.

6. An autonomous emergency braking (AEB) method comprising:
-
detecting moving objects moving toward a host vehicle in a direction transverse to a current traveling direction of the host vehicle at crossroads during driving of the host vehicle, receiving a driving speed of a host vehicle; receiving a distance, and a relative speed between the host vehicle and each of the moving objects or peripheral images, from one or more sensors; establishing a collision boundary based on the driving speed of the host vehicle; estimating positions of detected the moving objects; determining a time to collision (TTC) between the host vehicle and each of the moving objects based on the estimated positions of each of the moving objects and the collision boundary; selecting a control object among the detected moving objects based on the ITC; and warning a driver of the host vehicle or performing autonomous emergency braking (AEB) of the host vehicle. - View Dependent Claims (7, 8)

9. An autonomous emergency braking (AEB) system comprising:
-
a monitoring sensor configured to obtain detection information for calculating a distance between the host vehicle and moving objects and a relative speed of the moving objects, and transmit the information to the ECU; and the ECU configured to; determine a time to collision (TTC) of the host vehicle with each detected moving object moving toward the host vehicle in a direction transverse to a current traveling direction of the host vehicle; select an object among the detected moving objects having a smallest TTC as a control object; and provide a warning signal to a driver of the host vehicle or perform AEB of the host vehicle based on the TTC between the host vehicle and the control object. - View Dependent Claims (10, 11, 12, 13, 14)
