The Happy Peace Bike
Defining un-measured variables
 The variables we decided to characterize are:
Acceleration
 Deceleration
 Lateral Acceleration
 Tire temperature
 Lean angle
 Suspension travel
 GPS (time and donations permitting)
Although engine speed and velocity are already measured
by standard gauges, we decided to also transmit these
data values for correlation with the other acquired data.


Many sensor boards instead many sensors to one board
•Sensors closer to ADC
•Able to create more extensible system

Found signals generated from OEM sensors were pulse signals with
frequency proportional to speed.
OEM sensor pulse will be used as clock input for both
microcontroller counters, set to count-up on each rising edge.
External LM555 Timer will be used to generate interrupts for regular
calculation of speed and RPM.
Mostly clean square wave with 14.8V Amplitude
Some filtering is desired to eliminate the slight noise observed for
clock signal use.
TPS is analog signal from 0V – 14.8V proportional to throttle
position
Signals will need to be scaled for 3.3V input to microcontrollers.

 Power will be derived from the 12 volt DC
motorcycle battery (outputs 12V-15V)
 Using voltage regulators we will step-down
the 12V-15V to 12V, 5V and 3.3V
 Board will be attached to Data Handler board
with headers to allow for swapping power
