This is how Ride-By-Wire technology works

Ride-By-Wire technology was introduced in 2006 by Yamaha in its YZF-R6 motorcycle. By taking a computer and placing it between the throttle and the throttle of a motorcycle, many internal cogs of the motorcycle have been smoothed out and made more efficient, practical and efficient. In doing so, the systems became more compliant with emissions standards and capable of performing several tasks that were previously considered contradictory. This new system relies on sensors and wires that transmit information to the aforementioned computer, and it builds on the systems that came before it.

The powerful predecessors of technology

This technology is a bit more new and innovative, but it is taking root in several forms of technology that came before it. Before ride-by-wire technology became mainstream, early carburetors relied instead on a butterfly valve for airflow control via a passive fuel supply.

When the handle was twisted, more air was admitted into the engine, which allowed more fuel to be sucked into the cylinder, before finally being introduced into the engine when low pressure in the throat of the engine. carburetor caused fuel to be sucked from the tank. . Although this design evolved from its earlier form just described, the design was still a butterfly valve. It has simply been adapted to accommodate more powerful and dynamic engines.

After the butterfly valve came the design of the slide throttle, where the twist of the group pulled a cable which, when attached to other parts, became something of an accelerator. After that came a constant speed carburetor which allowed the pilot to control the throttle while managing air regulation via an intake vacuum on the side valve. This design gained popularity for its ability to effectively regulate emissions, which had been quite difficult to regulate and modify with precision until then.

It all started with Yamaha

Yamaha was the first company to officially implement Ride-By-Wire technology in their bikes. In 2006, Yamaha decided to introduce this new technology in its 2006 YZF-R6 motorcycle. This new technology shone, as it was able to give gaping intakes for power without sacrificing the predictable power of fuel injection and smaller carburetors.

Basically, a computer was placed between the rider’s right wrist and the throttle plates for regulation purposes, so when the rider turns the throttle, the computer calculates engine speed, vehicle speed, selection speed and other factors, and uses that information to decide how much the throttle should be open.

As a result, power is delivered much more easily than before, and the computer acts as an intermediary between the handle and the butterflies, robbing them of their once direct relationship. The mechanical connection between the throttle and the throttle is now cut and replaced with sensors and wires that connect the computer. In addition, the power of the fuel never reaches the rear wheel in lower gears, as the power of the lower gear is now automatically adapted thanks to the computer.

Various fuel and ignition boards were previously responsible for this task; ride-by-wire technology has now made them superfluous. The computer now allows the amount of fuel it chooses to enter the motorcycle engine. The sensors allow this mixing in the engine after detecting the position of the throttle, its actuators modifying the position of the throttle accordingly.

Oddly enough, the introduction of this new technology has changed some naming conventions for adjacent parts. The throttle is now electronic throttle control, the brakes are now Brake-By-Wire and the steering is now Steer-By-Wire, all a nod to ride-by-wire technology.

Multiple aspects proven to be beneficial

Ride-By-Wire technology has several features that have proven to be practical, effective and efficient. This technology has helped advance peak performance as all parts are now regulated in tandem without sacrificing the handling of the bike. The response can be further modified to create different riding modes, specially designed for specific purposes.

The computer interposed between the accelerator and the accelerator also makes it possible to access and modify more directly the cruise control and traction control. When it comes to emissions control, the ride-by-wire took the aforementioned constant speed carburetor and brought it to its logical conclusion in being able to prevent excessive emissions without compromising the response or horsepower of the engine. ‘accelerator.

Ride-By-Wire technology can also be programmed at certain HP levels to comply with specific country regulations, instead of having to manufacture multiple motors that would each be regulated to specific output power levels. The trap ? A ride-by-wire system is incredibly difficult to build, and if something does break, the repair will be detailed, time consuming and expensive.

If the technology starts to become problematic, there are several safeguards to prevent it from crossing a line. An important part of the ride-by-wire technology is the dual sensors placed at the throttle tube or wherever the rider’s commands can be received. A discrepancy between the signals from the driver and the computer will be noted, and if the parts do not conform to the command, a limp home mode will be activated as a fail-safe.

Additionally, Yahama can force the throttles to close via an additional mechanical linkage if an electronic aspect stops working. In this situation, the bike will have a fixed amount of reduced power to allow the rider to get home safely.
