2024-2026 Controls Hardware

WIP (not approved by Emech+Electrical, wanted to put on here for first draft of system diagram):

Controls:

• We have planned to have ~5 unique PCBs:

  • Controls Leader SOM (LSOM) - 1

  • Controls Peripherals (PSOM) will handle: - 6 PSOMs

    • Lights Daughter, 5 PSOMs

    • Pedals Daughter, 1 PSOM

  • Network Switch for PoE

• Other relevant pieces of hardware:

  • Prohelion Wavesculptor 22 Motor Controller: 14kw max output, 140V max input

    • Note: this is referenced throughout our software as the Tritium Wavesculptor, because Tritium used to own the product before Prohelion bought out that company.

    • Datasheet

    • User Manual

  • Mitsuba Motor: Three-phase, 96V nominal (160V max), 2000 watt nominal (5000 watt max).

  • Switches/Buttons on Steering Wheel

    • Regen enable

    • Cruise enable

    • Cruise set (merge with above?)

    • Cruise increment and decrement

    • Turn Switch (Left/Off/Right)

  • Switches/Buttons on Dashboard

    • Ignition Switch 3 Position

    • Supplemental power (dash will be made around this, does not go on dash itself)

    • Gear Switch (Forward/Neutral/Reverse)

    • Hazard Switch

    • Indicator lights (or on display? Includes turn, BPS Fault, Heartbeat)

    • Car Reset

  • Pedals

    • Accel potentiometer

    • Brake line sensor

    • Brake potentiometer sensor

  • Backup Camera x1

  • Blindspot Cameras x2

  • Display

    • Camera Feed x3

    • All gears and interaction/telemetry data

  • Lights

    • Brake Lights x3 (2 in back and one on canopy)

    • White Head Lights x2 (on front)

    • Amber Side Lights x4 (front, side)

      • amber side back lights are optional as brake lights can be interchangeable

Estimated Power Draws:

• Full system draw: ~18.5W(?)

  • One white light: 12.5V x .204A = 2.55W
