First Claim
1. An adaptive cruise control (ACC) system for a vehicle, the ACC comprising:
- a vehicle speed sensor configured to detect a speed of the vehicle and output an indication of the detected speed;
a user interface;
a steering angle sensor configured to provide an indication of the direction a driver is steering the vehicle;
a forward facing sensor configured to detect objects in front of the vehicle and to provide an indication of the objects; and
an engine control unit (ECU) including an adaptive cruise control (ACC) and configured toreceive an indication from the user interface to set a cruising speed for the vehicle,receive the indication of the vehicle'"'"'s speed from the speed sensor,receive indications of detected objects from the forward facing sensor, to receive indications of the steering angle from the steering angle sensor,determine whether to continue following a target vehicle based on the steering angle, and a projected path of the vehicle, andaccelerate the vehicle to the cruising speed when the ECU determines not to continue following the target vehicle,wherein determining whether to continue following a target vehicle based on the steering angle includes determining when the driver bumps a steering wheel in a direction opposite of the target vehicle.

Abstract
An adaptive cruise control (ACC) system for a vehicle. The ACC includes a vehicle speed sensor, a user interface, a steering angle sensor, a forward facing sensor, and an engine control unit (ECU). The vehicle speed sensor is configured to detect a speed of the vehicle and output an indication of the detected speed. The steering angle sensor is configured to provide an indication of the direction a driver is steering the vehicle. The forward facing sensor is configured to detect objects in front of the vehicle and to provide an indication of the objects. The ECU includes an adaptive cruise control (ACC) and is configured to receive the indications from the sensors, and to determine whether to continue following a target vehicle or to release the target vehicle and accelerate the vehicle to a cruising speed.

7. A method of operating an adaptive cruise control (ACC) system of a vehicle, the method comprising:
-
determining, by the ACC, a predicted course for the vehicle; detecting, by the ACC, a target vehicle in the predicted course of the vehicle; adjusting the speed of the vehicle to maintain a distance between the vehicle and the target vehicle; determining, by the ACC, that the target vehicle is diverting from the predicted course; receiving an indication of a steering angle from a steering angle sensor; determining whether to release the target vehicle based on the steering angle and a projected path of the vehicle; accelerating the vehicle, by the ACC, to a previously set cruising speed when the ACC determines to release the target vehicle, and wherein determining whether to release the target vehicle based on the steering angle includes determining when the driver bumps a steering wheel in a direction opposite of the target vehicle. - View Dependent Claims (8, 9, 10, 11, 12)
