Vehicle Performance Meter
The DomMeter is a car performance meter that measures acceleration to compute values important to car enthusiasts. Specifically, the DomMeter calculates the 0-60mph time, 0-30mph time, 0-100mph time, quater mile, eighth mile time and braking time, the max acceleration during that interval, distance travelled in feet and max horse power generated (after drag, roll losses and drive train losses). This is all accomplished by sampling an analog accelerometer's output and performing computations on the value of acceleration. Integrating accerlation yields speed. Integrating speed yields distance.
.:HIGH LEVEL DESIGN:.
We share a passion for performance cars. Our holy grail of a performance car is a sub 5sec 0-60mph split. Additionally, Dominik works on the FSAE racecar here at Cornell and desires a way to measure performance. There are commercial products that do the same thing and even more, but this project gave us the opportunity to have our own, at a cost of only our labor.
There are basically 5 components to the DomMeter : The accelerometer, the lcd display, the analog amplifier, regulator, and the MCU.
