Ride by Wire
Operating logic
Those riding motorbikes do not require a specific throttle valve opening from their engines but actually
a specific torque. The Ride by Wire system has been so designed that the throttles of the throttle bodies
are mechanically isolated from the throttle control; their actuation depends exclusively on 2 electrical
motors controlled by the control unit. The control unit refers to specific handle maps to determine by
how much and how quickly the throttle valves are opened. The parameters influencing the handle map
are as follows:
•
Handle aperture
•
Engine rpm
•
Handle aperture rate
The Marelli control unit performs the following functions:
1. Implements the necessary strategies for calculating torque demand
2. Operates the sensors and actuators necessary for system function
3. Safety checks for the Ride by Wire system
