Air temperature
3 - System safety checks
The checks are structured in several levels:
•
Level 1 - sensor correct operation
•
Level 2 - comparison between requested torque and estimated torque generated by the
engine
•
Level 3 - a microprocessor controls the correct operation of the regular microprocessor
The consequent maintenance operations may be of different gravity according to the level and the
defective component:
A the malfunction does not affect riding in safety, the warning light turns on, the word Service is dis-
played, the signal recovery value considered not reliable is used and the engine works regularly.
B the malfunction may affect riding in safety, the warning light turns on, the message Urgent Service is
displayed, the torque demands are not fully activated (reduced torque).
C the malfunction may affect riding in safety, the warning light turns on, the message Urgent Service
is displayed, the engine operates in Limp Home function (accelerated idle), the throttles which are at
the position exclusively depending on the springs are not moved. The engine may shut off during the
operation if it is running at idle speed and the gear is in neutral.
D the malfunction may affect riding in safety, the warning light turns on, the message Urgent Service
is displayed, the engine stops running.
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
