Driver assistance system

A driver assistance system for a vehicle having a steering holding section that is held by a driver who is seated on a driver's seat, rotates about a rotation shaft in a vehicle front-rear direction, and thereby steers a vehicle, the driver assistance system comprising:

• an operation member having an operation section disposed such that the driver can manually operate the operation section to accelerate/decelerate the vehicle when the steering holding section is held by the driver;
• and
• a support member that supports the operation member in a slidingly displaceable manner along a rotation shaft direction in which the rotation shaft extends;
• and
• transmission means that mechanically or electrically transmits a sliding displacement amount in the rotation shaft direction of the operation member to an output control section of a drive source for the vehicle, wherein
• when the steering holding section is seen from the driver side, the operation section is disposed along said steering holding section at a position proximal said steering holding section and between the steering holding section and the rotation shaft, and
• a movable range of the operation member is such that, in the rotation shaft direction, the operation section is movable from a first position closest to the driver where the operation section is aligned with an end surface on the driver side of the steering holding section in a direction normal to the rotation shaft direction, to a second position farthest from the driver overlapping with the steering holding section.
