Driver assistance system and driver assistance method

摘要

Risk and/or control status are presented in such a way that the vehicle driver can easily comprehend the fact. Upon detecting risk during driving a vehicle, the vehicle is controlled and information of at least one of the risk and the status of the vehicle being controlled is presented in visual form. In addition, the driver's initiative (D) in driving the vehicle is calculated (step S2), and the visual form, in which the information is presented, is altered depending on the calculated driver's initiative (step S3). When, for example, a lane departure prevention control works, the status of restraining lane departure is presented by arrow(s) in an anti-lane-departure direction opposite to the direction of lane departure. The size (including the length and the width) and color of the arrow(s) are altered depending on the initiative (D). Here, when the initiative (D) is at a low level, the arrow(s) is set in color, for example, ‘red’ and increased in size because the risk that the tendency of lane departure may increase becomes high.
