FSAE 2003
Vehicle Electronics
Mike Stamm
2
MYTH wire taillights (design them instead)
real-life engineering skills
to-date mechanical aspects
new vehicle electronics
long-time goal
take control of the car from the MECEs D
FSAE-Elec background
3
Automobile Systems Controller (car brain)
data acquisition
ECU
HMI (plain english steering wheel)
drive - by - wire
bottom line easier tuning and driving
4
Data Acquisition ( DAQ )
sensors 5 (6-10 women) vs 32 senses
i.e. crank angle, rpm, temperature, etc
filtering and recording brain involved!
32sens8S/s3600s approx 1mio samples / hr
1MECEHP48 1month 1 µC 1/8s
5
ECU
motorola PowerPC (TAG-McLaren)
monitors sensor values (engine load, rpm etc)
decide on fuel injection / spark timing
interface to ALL electrical systems
nerve center of the car
6
HMI
control center
hands-on interface to ECU
intelligent and expandable
this ones up for grabs!
7
Drive - by - Wire
less cable, more wire
control electronics betw. foot and throttle
flexible ratios
smooth out a clog-shoed driver
8
what we need
motivated individuals
give up some time
get some wild jobs solid efforts pay off !!!
questions?
