  • Blended electrical/friction braking system with electric brake feedback monitor and method of use thereof
    Publication number: 20020117984
    Abstract: 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.

  • Electromagnetic interference detection system for mass transit vehicles with electronic propulsion
    Patent number: 5713541
    Abstract: An electric power vehicle includes a propulsion system connected to a direct current (DC) source via a supply line. The propulsion system converts the DC supplied via the supply line to an AC electrical power to operate an AC motor at a desired level. An electromagnetic interference detection system for the vehicle includes an EMI processor connected to a current transducer and the propulsion system. The transducer detects AC signals appearing on the supply line and provides an output to the EMI processor. The EMI processor determines the frequency, amplitude and duration of the detected AC signals and causes the propulsion system to adjust the AC electrical power supplied to the motor as a function thereof.
