To provide an acceleration feeling controller capable of preventing a driver from feeling uncomfortable by avoiding a change in the feeling of the operation of an accelerator pedal by the driver when giving pseudo acceleration to the driver.

The acceleration feeling controller 1 includes: an insufficient acceleration calculation means 6b for calculating an insufficient acceleration A when an constant pedal opening is kept based on a constant acceleration feeling line and a constant pedal opening line; an inclination calculation means 6d for calculating an inclination θ corresponding to the insufficient acceleration A; a backward inclination means 3a for inclining a seat S of the vehicle backward for the inclination θ; a stroke quantity compensation means 6e for compensating the stroke quantity ST of the pedal of the vehicle for the compensation quantity ΔST corresponding to the inclination θ; and a controlling stroke quantity compensation means 6f for compensating the controlling stroke quantity SS corresponding to the stroke quantity ST used for controlling a drive source of the vehicle for the controlling compensation quantity ΔSS corresponding to the compensation quantity ΔST.
