PCB board aquiring data from the front side of the vehicle.

Features

• APPS
  • two outputs: power (+5V) lines with separate regulators
  • two inputs: APPS signal lines
  • ability to disconnect the shutdown circuit
• Data acquisition
  • front and rear brake pressure measurement
  • safety sensing
  • imu measurements
  • steering wheel position sensor?
  • brake pedal position sensor?
  • suspension position sensors?
  • Laptimer

APPS

Linear potentiometers:

Front and rear brake pressure

Two analog, 5V sensors

Safety (shutdown circuit) sensing

The safety state will be measured at:

• left kill switch
• right kill switch
• driver's kill switch
• inertia switch
• BSPD
• overtravel
• ASB

IMU measurements

ISM330DHCX mounted on external board with swps:

Steering wheel position sensor

Sensor: AS5600

The sensor will be placed on a mini-board. The angle signal uses PWM

Brake pedal position sensor

Same as APPS

Suspension position sensors

Two linear potentiometers
