A device for remotely changing the control of power generated by an internal combustion engine of a recreational vehicle driven by a driver controlling an accelerator pedal. The device includes a remote control, sending a signal for modulating the power and/or speed of the engine. The device comprises a system for measuring the position of the accelerator pedal, a system for receiving the signal for modulating the power and/or speed, a system for controlling the intake of gases into the engine, and an electronics module connected to the various systems, establishing rules for controlling the intake control system, depending on the position of the accelerator pedal and the received modulation signal.

An electro-mechanical actuation control system includes: a comparator configured to compare a desired vehicular component data to an actual vehicular component data; a controller that is configured to enable control of vehicular components and includes vehicle component controllers; a transmitter configured to remotely transmit input signals to the vehicle; a receiver configured to receive the transmitted input signals from the controller and mounted on the vehicle; an actuator driver configured to receive inputs from the receiver and mounted on the vehicle; an actuator coupled to the actuator driver and configured to be operable in any one of an enabled state and a disabled state caused by the actuator driver; and one or more vehicle components that comprise a drive unit including one of an engine assembly, an electric motor and a combination of the engine assembly and the electric motor.

Disclosed is a throttle quadrant arrangement utilizing a throttle lever mechanically connected to three Rotary Variable Differential Transformers (RVDTs). The signals from the RVDTs are monitored by a process where the processing component. More specifically, RVDT outputs are monitored by the engine control system to determine if they are outside a predetermined range of operability. If an RVDT is not operable, the engine control system establishes a thrust output using the signal from one of the functional two. If only one or none are within the range, the system moves on to a default mode.

A control method of a butterfly valve of an internal combustion engine, when said internal combustion engine is running, wherein said butterfly valve is controlled by means of a control signal, indicative of an angular position of said valve, the method comprising a step of applying a first limiting filter of a gradient of said control signal, when a ratio between a target pressure downstream of the butterfly valve and a measured pressure upstream of the butterfly valve is greater than a first predetermined threshold.

A throttle valve device includes a coil spring arranged in a body between a valve gear and a valve and having a spring end extending radially outward. A first guide covers an end of the coil spring and includes a first guide hook that contacts the spring end. A body hook in the body is capable of contacting a tip end part of the first guide hook. A valve gear hook in the valve gear is capable of contacting a base end part of the first guide hook. The first guide hook has a protrusion protruding toward the spring end between the tip end part and the base end part. The first guide hook is deformable by receiving the spring force at the protrusion as an effort while a fulcrum is at a contact between the first guide hook and the body hook or the valve gear hook.

A throttle valve includes a housing, an electric motor and an insert. The electric motor is accommodated in the housing and drives opening and closing of an air flow passage of the throttle valve. The insert is partially enclosed in the housing and includes an electrically conductive insert body at least partially accessibly exposed from the housing, and an electrically conductive electric motor connector. One end of the motor connector is electrically connected to the insert body, and the other end thereof is electrically connected to the electrically conductive housing of the electric motor.

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.
