CLASSIC COMFORT
“Merging the past with the present”
PROJECT DESIGN
Problem Statement
Rhyvle Technologies will provide a module which will attach to the current wiring harness
produced by Painless Performance; allowing control of certain electrical systems in the car.
Functional Requirements
Our biggest concern with creating the Classic Comfort module is keeping our costs down. We
would like our final prototype to be approximately $150 and a final manufacturing cost of $100. The
size of the module should be small enough to allow for it to be easily mounted under the dash of a
classic car and be hidden from the consumer.
The module must be able to interface with the ignition circuit in order to have an easy access kill
switch. When the kill switch is activated, the car will not start. This feature was requested by Painless in
order to lower the amount of car thefts on their customers.
The radio delay will allow for operation of the radio even after the engine of the car has been
turned off. The radio will stay on after the car’s engine has been turned off until the driver-side door
has been opened. At this point the system will turn the radio off.
The headlight delay will keep the headlights on for a desired period of time after the car has
been shut off. This feature is triggered once the engine has been shut off and unlike the radio delay
opening or closing the door has no effect on its timing.
The dome light dimming process will occur when the engine is off. When any door is opened
the dome light will simply come on. When the door is closed the dome light will fade out over a short
time period specified by the user. When the engine is running the dome light will operate normally with
no dimming.
Daytime driving lights will be another feature which will be added on the vehicle. Whenever the
engine is turned on the headlights will be turned on automatically. The rear taillights and the
illumination in the dash board will not be turned on while the user is driving the car. The taillights and
the dash board will turn on when the user turns their car lights on for nighttime driving. If the user
simply wants to turn the daytime drive lights off then they can simply switch their lights to the on
position, if not already, and then turn them off normally. This will send a signal to our device to turn the
daytime driving lights off until the engine is shutoff.
