[BUG] Toggling to cruise mode starts ramp up from 0watt #5

Open Frans-Willem opened 5 years ago

Frans-Willem commented 5 years ago

To reproduce:

Start biking with a moderate or high assist level
Aim for 30km/h (or something else?)
Enable cruise control

Observed behavior:

Before cruise activates, the motor will be pushing 200+ watts
Once cruise activates, this suddenly drops to 0 watt, as indicated by the LCD, as well as felt in your legs.
You start to lose speed
Power will (relatively) slowly build up again once you lose speed.
It takes a few seconds for cruise to stabilize and hold your desired speed.

Expected behavior:

Seeing as the motor was already pushing 200watts, it shouldn't suddenly back off to 0 watts.
the current/wattage at the time of activating cruise should be a good point to start from
Enabling cruise should not suddenly lead to a drop of power and speed.
