First came DCT, now it’s the E Clutch…
We popped past Honda the other day to collect their new Activa Scoot when we saw a new Transalp lurking in the corner. Being the curious lot that we are, we took a closer look and realised that it is the first E Clutch model to hit our shores.
What is E Clutch?
According to Honda, “The Honda E-Clutch is an electronic control technology that automatically controls clutch operation without the need for the rider to operate the clutch lever,enabling smooth starting and gear shifting. Developed on the concept of “Take You to the NEXT STAGE,” this new technology was created in pursuit of a high level of sportiness, comfort, and peace of mind. As a result, it delivers an improved riding experience for a wide range of riders who seek the fun of riding.”
It allows riders to choose themselves whether or not to operate the clutch lever on manual transmissions.
But isn’t that DCT?
Nope. According to Honda, DCT is an automated gear shifting system that automatically changes gears without the rider having to operate the clutch lever while the E-Clutch only automates the clutch operation, making it a manual transmission system with the rider always in control of gear shifting. In this way, the clutch and transmission mechanisms are the same as on conventional manual transmission motorcycles.
The innovative feature of Honda E-Clutch is a structure that offers independent actuation from either manual clutch operation using the handlebar-side clutch lever or automatic clutch control using the motors. The new clutch lever shaft is a structure of three parts; the clutch side that engages with the clutch lifter piece, and the other side that comprises a manual operation side (top) and a motor control side (bottom) situated on the same axis. Even during motor control, manual operation is possible via an override. By operating the clutch lever with the left hand, riders can disengage the clutch whenever they wish.
At the heart of the Honda E-Clutch system is a drive unit and motor control unit (MCU) comprising two small motors and gears, and a three-part clutch lever shaft for moving the clutch lifter piece. The system itself is made up of an engine control electronic control unit (ECU) that operates in conjunction with the MCU in response to data sent from various sensors.
Automatic clutch control parameters use many different signals, including engine RPM (crankshaft), throttle angle, gear position, gear shift pedal load, clutch disengagement, meter indicators, and front and rear wheel speed. Referencing and cooperating with computations from the engine control ECU, the system then applies appropriate clutch control.
So there you go. The system has been tested extensively overseas and as we understand it, it is selling really, really well compared to manual options.
This specific bike is here for homologation (Being checked out by the boffins in government), and it won’t be too long until it makes its way to showroom floors…
You bet your ass we’ll ride it and tell you what we think…
