A vehicle control device includes a depression amount detection unit, a depression speed detection unit, a reaction force setting unit, and a reaction force generation unit. The reaction force setting unit sets a value of a reaction force in a manner of separating characteristics into advancement characteristics and return characteristics. The reaction force setting unit sets a value of a reaction force with respect to a depression amount in such a way that, in main advancement characteristics except for both ranges corresponding to start of depressing and end of depressing among advancement characteristics, a degree of increase of a value of a reaction force relatively decreases, as a depression amount increases until a predetermined ratio with respect to a maximum depression amount of an accelerator pedal reaches, and a degree of increase of a value of a reaction force relatively increases, as a depression amount increases after the predetermined ratio reaches; and sets a value of the reaction force in such a way that a value of the reaction force decreases, as a depression amount decreases.

Vehicle control device

An operation device in which in-vehicle devices are controlled in accordance with a rotation angle of an input unit operated by a manual operation of a driver, which includes a commander rotatable about a rotation shaft, a rotation angular speed calculation unit that detects a rotation angular speed of the commander, a motor that gives an operation reaction force for each predetermined rotation angle of the commander, and an ECU that controls the operation reaction force given by the motor, wherein the ECU changes the operation reaction force in accordance with the rotation angular speed detected by the rotation angular speed calculation unit.

Operation device for vehicle

The present invention includes: a visual perception target determination unit for determining a visual perception target by using a saliency model for determining that an object to be visually perceived at a glance is a visual perception target, a surprise model for determining that an object behaving abnormally is a visual perception target, and a normative model for determining that an object to be visually perceived by a viewing action of a driver serving as a norm is a visual perception target; and a visual guidance unit for determining whether or not an overlooked visual perception to which a line-of-sight direction detected by a line-of-sight detection unit is not directed is present, and guiding a line-of-sight of a driver toward the overlooked visual perception target, when the overlooked visual perception target is present.

Visual perception assistance system and visual-perception target object detection system

An edge of, for example, a windshield which serves as range of vision is defined by front pillars, a roof, and a dashboard. A modification area is provided at a peripheral portion of the windshield. In the modification area, visual saliency (visual conspicuousness) can be partially increased by means of, e.g., liquid crystals.

Device controlling range of vision

A floor structure on a driver side of a vehicle where a control pedal, such as a brake pedal, adapted to be depressedly operated by a driver seated in a driver seat arranged at a front of a passenger compartment. The floor structure has a heel-placement zone which is provided on an approximately horizontal floor portion located rearward of a depressing point of the control pedal, and formed to have a frontward region adapted to allow a short person seated in the driver seat place his/her heel thereon and a rearward region adapted to allow a tall person seated in the driver seat place his/her heel thereon. The heel-placement zone includes an inclined surface portion formed in at least part thereof in such a manner as to rise relative to a surrounding area of the floor portion and has an upper surface extending obliquely upwardly and frontwardly. The floor structure can adjust a driving posture easily and adequately with a simple structure to allow a driver seated in the driver seat to adequately operate the control pedal.

Driver-side floor structure of vehicle

A driving position adjusting device comprises a seat-position adjusting mechanism to adjust height and seat-face angle of a seat cushion in accordance with longitudinal movement of a driver's seat, and a floor adjusting mechanism to adjust a height of a floor board in accordance with the operation of the longitudinal adjustment of the driver's seat, wherein the seat-position adjusting mechanism is configured so that an inclination angle of the seat cushion becomes smaller as the driver's seat is moved forward from a middle position, and the floor adjusting mechanism is configured so that the height of the floor board becomes higher as the driver's seat is moved forward from the middle position. Accordingly, the sitting position of the driver and the operational function of the operational pedal can be provided properly regardless of the body size of the driver.

Driving position adjusting device

A steering apparatus for a vehicle, which can reduce the steering load and allows accurate steering angle control, is provided. In the steering apparatus for a vehicle, an estimation unit estimates a mechanical impedance upon a driver's steering manipulation. A control unit controls the steering reaction force of a steering wheel based on the estimated mechanical impedance.
