🦇 What Is Throttle By Wire

(Throttle-by-wire and steer-by-wire exist as well.) Sensors and actuators read the amount of pressure a driver inputs, and this force is transferred to all the brakes from the master cylinder Throttle by wire is a simple, potentiometer style (think volume switch) design that when the throttle tube is moved, the values are calculated, and an electrical impulse is sent to the throttlebody, and a small electric motor moves the throttle plate, rather than manual linkage via cables. Instead, the throttle valve is electronically actuated by the ECU (Electronic Control Unit) using inputs from the accelerator pedal. This system is known as Drive-By-Wire. Throttle by wire enables higher engine performance through what we know as the virtual powerband. Kevin Cameron shows us how it works, and why it's a good thing. Throttle by wire has been present for a long time, I found this tidbit that might be interesting to you. When you give command of the throttle to an electronic device, you want to know that the bike won't go all HAL 9000 on you. No need to worry; there are myriad safeguards in place. For starters, modern RBW systems employ dual sensors at the Throttle Body and Accelerator Pedal With a few exceptions, the electronic throttle body is very similar to a cable-operated throttle body. One of the most noticeable exceptions is the addition of the throttle actuator control (TAC) motor. This is used to open and close the throttle plate based on commands from the ECM. The Twist Grip Sensor Kit enables installation of accessory handlebars on vehicles equipped with throttle-by-wire. Details. Fits '08-'13 Touring models (except Trike) equipped with internally routed switch-wires. Fits with either stock or accessory handlebars. Installation Instructions can be found with the appropriate handlebar. Drive by wire is a technology that replaces traditional physical connections with a wire carrying an electronic signal. For example, on gasoline engines the throttle cable normally runs from the gas pedal to the butterfly in the throttle body that limits the amount of air going into the engine. Throttle by wire has nothing to do with fuel/spark/inginition mapping. The adaptations for that are between the engine and management system. What if does/can do is adjust the throttle response to the grip, this is how the wet/sport/race mappings adjust throttle response, much like changing the cams on cable throttle grips makes the grip more UIFU.
