Abstract
A steering intention determination device includes a calculation unit that calculates a value based on the product of a steering angular velocity and a steering torque and the product of a steering angle and the time differential value of the steering torque, and a determination unit that determines that the driver has a turn-and-steer steering intention in a case where the value is equal to or greater than a predetermined value, determine that the driver has a steering holding intention in a case where the value is less than the predetermined value and the absolute value of the steering angular velocity is less than a predetermined angular velocity, and determine that the driver has a switchback steering intention in a case where the value is less than the predetermined value and the absolute value of the steering angular velocity is equal to or greater than the predetermined angular velocity.
