Driver assistance system and driver assistance method
First Claim
1. A driver assistance system comprising:
- at least one controller configured to provide a plurality of vehicle motion controls for controlling a vehicle based on a detected risk during driving the vehicle;
a display device configured to present information, in visual form, regarding at least one of (i) the detected risk, and (ii) an operating state of at least one of the vehicle motion controls;
a calculating unit configured to calculate a driver'"'"'s contribution amount based at least on a first ratio of (i) motion of the vehicle depending on the driver'"'"'s operation, to (ii) total motion of the vehicle; and
an altering unit configured to alter the visual form in which the information is presented based at least on the driver'"'"'s contribution amount calculated by the calculating unit.

Abstract
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.

20. A driver assistance method comprising:
-
controlling a vehicle using at least one of a plurality of vehicle motion controls based on a detected risk during driving the vehicle; presenting information, in visual form, regarding at least one of (i) the detected risk, and (ii) an operating state of the at least one of the vehicle motion controls; calculating a driver'"'"'s contribution amount in driving the vehicle based at least on a first ratio of (i) motion of the vehicle depending on the driver'"'"'s operation, to (ii) total motion of the vehicle; and altering the visual form in which the information is presented based at least on the calculated driver'"'"'s contribution amount.
