Abstract
A driving support device may be configured to calculate a target steering angle for allowing a vehicle to travel along a target course; set, as a reference steering angle, a steering angle when a difference between the steering angle and the target steering angle is small; calculate an indication value indicating intention of a driver's steering operation as a sum of a first product of a corrected steering angle and a steering torque, a second product of a derivative of the corrected steering angle and the steering torque, and a third product of the corrected steering angle and a derivative of the steering torque; and correct the target steering angle based on the indication value so that a target driving support torque is corrected in accordance with the intention of the driver's steering operation.
