A system for amplifying haptic effects provided by a push-pull actuator includes a housing component, a push-pull actuator coupled to the housing component and configured to provide a force and a displacement, a lever component including a lever arm and a fulcrum, and a haptic touch surface coupled to the lever arm via an output interface. The push-pull actuator is via an actuator mount. The amount of displacement transferred to the haptic touch surface from the push-pull actuator is reduced by the lever component and the amount of force transferred to the haptic touch surface from the push-pull actuator is increased by the lever component. The system may include a material stop coupled to the housing component that when compressed by the haptic touch surface exhibits hysteresis to dampen the haptic touch surface.

There is described a motor vehicle control device (10), comprising an outer housing part (12), a control unit (14) including a control surface (16) and a printed circuit board (22) which is carried by a circuit board carrier (28) that is at least partly accommodated and floatingly mounted in the outer housing part (12).

An actuator applies a reaction force to a pedal lever to be depressed by a human driver. The actuator includes an electric motor, a speed reducer mechanism, an actuator lever and an angle detector device. The speed reducer mechanism includes: a motor gear that rotates integrally with the electric motor; an output gear that rotate integrally with an output shaft; and an intermediate gear installed between the motor gear and the output gear. The actuator lever is driven by the output shaft and contacts the pedal lever. The angle detector device detects a rotational angle of the intermediate gear. The intermediate gear has: a large gear portion, which meshes with the motor gear; and a small gear portion, which meshes with the output gear. The small gear portion is integrally formed in one-piece with the large gear portion.
