Patent number: 6615118Abstract: An energy management system for use with off-highway vehicles, including locomotives, that traverse a known course. A processor determines power storage and transfer parameters, including data indicative of present and future track profile information. The energy management system controls the storage and regeneration of electrical energy. A hybrid energy locomotive system has an energy storage and regeneration system. In one form, the system can be retrofitted into existing locomotives or installed as original equipment. The energy storage and regeneration system captures dynamic braking energy, excess motor energy, and or externally supplied energy. The captured energy is stored in an energy storage system such as a battery, a flywheel system, or a capacitor system. The energy storage and regeneration system can be located in a separate energy tender vehicle. The separate energy tender vehicle is optionally equipped with traction motors.Type: GrantFiled: December 26, 2001Date of Patent: September 2, 2003Assignee: General Electric CompanyInventor: Ajith Kuttannair Kumar

Patent number: 6600979Abstract: Method and system for determining a reference speed indicative of true ground speed of a vehicle having a plurality of axles are provided. The reference speed for a designated one of the axles is dynamically adjusted to account for changes in vehicular acceleration that may occur while determination of the reference speed is being performed. The method allows collecting a stream of samples over respective sampling intervals of at least one motion-indication parameter corresponding to a respective axle of the vehicle. In one aspect thereof, one may use a torque reduction rulebase configured to avoid high torque reduction, and inaccuracies in the motion-indication parameter due to high levels of creep, if any, in a wheel of the respective axle. The method further allows estimating an inertia value for the vehicle based on respective changes in tractive effort and acceleration over each sampling interval.Type: GrantFiled: February 26, 2002Date of Patent: July 29, 2003Assignee: General Electric CompanyInventors: Ajith K.
