Autonomous emergency braking (AEB) based on vehicle turn state

A method of implementing autonomous emergency braking (AEB) for advanced driver-assistance systems (ADAS), the method comprising:

• identifying one or more targets external to a host vehicle;
• detecting a vehicle turn state of the host vehicle based on one or more inputs;
• and selecting an Autonomous Emergency Braking (AEB) algorithm to apply based on the detected vehicle turn state, wherein the AEB algorithm is utilized to initiate an AEB event to avoid collision with the identified target, wherein detecting the vehicle turn state of the host vehicle includes distinguishing between a U-turn state and a normal turning state, wherein a first AEB algorithm is utilized for the normal turning state, and a second AEB algorithm is utilized for the U-turn state, wherein the vehicle event history is utilized to distinguish between the U-turn state and an evasive steering state.

An advanced driver-assistance system (ADAS) comprising:

• one or more first sensors configured to generate first inputs related to targets sensed external to a host vehicle;
• one or more second sensors configured to generate second inputs related to a turn state of the host vehicle;
• and a controller configured to receive the first inputs from the one or more first sensors and the second inputs from the one or more second sensors, wherein the controller is configured to detect targets based on the first inputs received from the one or more first sensors and detects the turn state of the host vehicle based on the second inputs, wherein the controller utilizes an autonomous emergency braking (AEB) algorithm to trigger AEB events to avoid collisions with the detected targets, wherein the controller modifies the AEB algorithm based on detected turn state of the host vehicle, wherein the controller calculates time-to-collision (TTC) with respect to each detected target, wherein the AEB algorithm initiates an AEB event if the calculated TTC is less than a TTC threshold, and wherein the controller modifies the AEB algorithm by decreasing the TTC threshold in response to the detected turn state indicating the host vehicle is performing a U-turn.
