Variable Documentation

GEAR_RATIO_DENOMINATOR

constexpr uint8_t PedalConstants::GEAR_RATIO_DENOMINATOR = 13

constexpr

Gear ratio denominator of the drivetrain.

Definition at line 46 of file Pedal.hpp.

GEAR_RATIO_NUMERATOR

constexpr uint8_t PedalConstants::GEAR_RATIO_NUMERATOR = 60

constexpr

Gear ratio numerator of the drivetrain.

Definition at line 45 of file Pedal.hpp.

INCH_PER_KM

constexpr uint16_t PedalConstants::INCH_PER_KM = 39370

constexpr

Inches per kilometer.

Definition at line 53 of file Pedal.hpp.

MAX_MOTOR_RPM

constexpr uint16_t PedalConstants::MAX_MOTOR_RPM = 7000

constexpr

Maximum motor RPM.

Definition at line 50 of file Pedal.hpp.

MAX_TORQUE_VAL

constexpr uint16_t PedalConstants::MAX_TORQUE_VAL = 32767

constexpr

Maximum torque value for motor controller.

Definition at line 51 of file Pedal.hpp.

MIN_REGEN_KMH

constexpr uint8_t PedalConstants::MIN_REGEN_KMH = 10

constexpr

Minimum speed (km/h) for regenerative braking to be active.

Definition at line 44 of file Pedal.hpp.

MIN_REGEN_RPM_VAL

constexpr int16_t PedalConstants::MIN_REGEN_RPM_VAL

constexpr

Initial value:

=
        (double)MIN_REGEN_KMH / MINUTES_PER_HOUR * INCH_PER_KM / WHEEL_DIAMETER_INCH / PI_ * GEAR_RATIO_NUMERATOR / GEAR_RATIO_DENOMINATOR * MAX_TORQUE_VAL / MAX_MOTOR_RPM

Final RPM = KMH -> Inches per Hour -> Inch per minute -> RPM at wheel -> RPM at motor Minimum RPM for regenerative braking to be active.

Definition at line 58 of file Pedal.hpp.

PI_

constexpr double PedalConstants::PI_ = 3.1415926535897932384626433832795

constexpr

Value of pi, unnamed to avoid clashing with Arduino.h's definition.

Definition at line 55 of file Pedal.hpp.

WHEEL_DIAMETER_INCH

constexpr uint8_t PedalConstants::WHEEL_DIAMETER_INCH = 13

constexpr

Wheel diameter in inches.
