Hi,
I know it's possible to split one throttle signal output from a single CA and send it to two motors, but the problem is that not all situations were meant to apply equal torque both at the front and the rear wheels.
For example: At uphill takeoffs, you would want to have more torque on the rear and control how much you apply on the front, separately.
On downhills, you would do the reverse while you regen and brake yourself. (and especially if it's raining you would apply much less braking torque on the rear)
I love Grin's approach where you use the same throttle also for regen by holding with the other hand the E-brake lever, but then you are unable to manually, and fully, control 2 different motors. (both for acceleration and deceleration)
It would require 3 hands for regen: One activating the E-brake lever, and the two others controlling independently the braking torque with the respective throttle.
I thought to use one of the legs/pedals to close a circuit, like a microswitch, that will enable regen mode, so the two hands can control the two throttles.
Has anyone done something like that before? It would be nice to see.
Or, do someone have an idea how such application can be approached when you have two throttles, two CA's, and two (but not interconnected) E-brake levers. (and only two hands)
The solution can be electrically. I can give you example: On one bike where I have a front DD and a rear non-regen geared motor, I have the left E-brake to signal the CA + using the throttle, or, I can press the right E-brake only and this one shorts the throttle CA output so I get maximum regen instantly. This is for emergency braking situations where you need to press both mechanical levers, and so you have the advantage of having the motor helping out as well. (and no need to hold the throttle)
I was already advised to to remap the throttle voltage->torque output on each of the controllers (Phaserunners), but this is an automatic approach which doesn't fit all scenarios, and will seriously hinder your accelerating/braking abilities when you do want to use both motors equally.
And last, I know there are bi-directional throttles but I have never experienced one, and they seem awfully inconvenient for your wrists if you do lots of motor-braking. Has anyone tried those and can share the experience?
