Abstract: A driver assistance system is provided that allows a driver to easily perform an accelerator operation by a finger of his/her hand while grasping a steering holding section. The driver assistance system includes an operation member near a steering wheel held by a driver, which rotates about a rotation shaft in a vehicle front-rear direction and thereby steers the vehicle. The operation member has an operation section that the driver can manually operate to accelerate/decelerate the vehicle, and includes a support member on the steering wheel, the support member supporting the operation member in a slidingly displaceable manner along a steering axial direction. The operation section is disposed near a radially inner side of a rim section of the steering wheel, and the operation section and the rim section overlap in the steering axial direction within a movable range of the operation member along the steering axial direction.

Abstract: A driver assistance system enables brake and accelerator operation by an operation bar in a manner close to a sense of a driver of a vehicle, regardless of the degree of operation of the operation bar. Embodiments include an operation bar extending downward toward a vehicle floor panel from a manual operation area where a seated driver manually operates the operation bar, and whose lower portion is supported in a slidingly displaceable manner along an axial direction in a front-down, rear-up tilted state. The operation bar includes a brake actuation section, below the manual operation area, that actuates a brake mechanism by sliding displacement of the operation bar in a front-down direction; and an accelerator actuation section that actuates an acceleration mechanism by sliding displacement of the operation bar in a rear-up direction that is a reverse direction on the same axis from the sliding displacement in the front-down direction.

Abstract: A driving assistance device enables a driver who manually performs an accelerator operation and a steering operation to easily retain an accelerator operation state in a constant state. A driving assistance device includes a manually operable accelerator operation unit in the vicinity of a steering wheel provided in front of a driver seat in a vehicle cabin. The accelerator operation unit is operable in a state where the steering wheel is gripped and an operation reaction force of the accelerator operation unit exhibits an inflection point POI at which the operation reaction force rapidly becomes large in response to an increase in an operation amount of the accelerator operation unit.
