SAE Technical Standards included in the CDS Rules

A3.11 SAE Technical Standards Access
A cooperative program of SAE’s Education Board and Technical Standards Board is making some
of SAE’s Technical Standards available to teams registered for any North American CDS
competition at no cost. The Technical Standards referenced in the Collegiate Design Series rules,
along with other standards with reference value, will be accessible online to registered teams, team
members and faculty advisors. To access the standards (1) your team must be registered for a
competition in North America and (2) the individual team member or faculty advisor wanting
access must be linked to the team in SAE’s system.

EV4.3 Grounding
EV4.3.1 All electrically conductive parts of the vehicle (e.g. parts made of steel, (anodized) aluminum, any
other metal parts, etc.) which are within 100mm of any tractive system or GLV component, and any
driver harness mounting points, seat mounting points and driver controls must have a resistance below
300 mOhms (measured with a current of 1A) to GLV system ground.
EV4.3.2 All parts of the vehicle which may become electrically conductive (e.g. completely coated metal parts,
carbon fiber parts, etc.) which are within 100mm of any tractive system or GLV component, must
have a resistance below 5 Ohm to GLV system ground.
EV4.3.3 Electrical conductivity of any part may be tested by checking any point which is likely to be
conductive, for example the driver's harness attachment bolt, but where no convenient conductive

== Design ==
* Compiled possible solutions for tradeoff analysis, building group knowledge of sensors and microcontrollers.
* Uncovering unknown components to the problem forced late redesign in system architecture. (Naive solution --> CPLD central control --> PCB control board)
* Design settled on a central PCB containing controls circuits, connected directly to vehicle sensors and switches.
* Some unexpected or misunderstood issues: Latching/reset button circuits, precharge/discharge circuits, galvanic isolation between HV and LV, safety interlocks
* Flowcharting/pseudocode for microcontroller and data-acquisition procedures before receiving devices

== Analysis ==
* Tradeoff analysis with decision matrices to select the many sensors, buttons, cables and connectors.
* RC-circuit discharge-time versus power-dissipation (for precharge/discharging of controller capacitors)

#Tips for calculating phasor quantities using the 50g:

## Adding ->V2, RECT and CYLIN to soft menu

* We often need to convert between rectangular and polar form. Lets add these commands to the CUSTOM softmenu.
* V2 builds a two-dimensional vector using the first two stack values and builds in polar/rectangular depending on mode.
* RECT and CYLIN don't convert the first stack value as I thought they did, but instead set the coordinate mode.
