A blended electrical/friction braking system includes an electric brake feedback monitor which monitors a first signal corresponding to an electric brake effort request of an electric motor of an electrically powered vehicle. The electric brake feedback monitor detects one or more electrical conditions of the electric motor during electric braking and selectively supplies/terminates the first signal to/from a brake controller as a function of the first signal and the one or more electrical conditions. In response to termination of the first signal thereat the, brake controller causes a friction brake of the vehicle to assume the entire braking effort of the vehicle.

Why it's free to use
- Filed April 25, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 25, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 25, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
