openscoot

An open source CAN based escooter controller

Primary design

Focus on throttle response, ebraking performance, and power management.

Throttle smoothing and braking

The throttle response should be smoothed, with different coefficients for increase and decrease. Braking performance needs to be maintained, and should override throttle smoothing.
