Control apparatus for hybrid vehicle

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.

Hybrid energy power management system and method

According to one embodiment of the present invention, a computer manages an electric vehicle charging transaction. A set of principals is identified associated with the charging transaction for an electric vehicle. A principal is an entity having an interest in the charging transaction. Electric vehicle charging information is retrieved from a set of sources. An energy transaction plan is generated during a pre-charge phase using the electric vehicle charging information and based on preferences of one or more principals to govern the charging transaction. The computer initiates a charging phase of the electric vehicle charging transaction for an electric vehicle connected to a charging station according to the energy transaction plan. The charging phase comprises charging the electric vehicle with electricity, storing electricity in the electric vehicle, and removing electricity to de-charge the electric vehicle. The computer settles the financial obligations among principals according to the energy transaction plan.

A computer implemented method, apparatus, and computer usable program product is provided for managing network based preferences associated with charging transactions for electric vehicles. The network based energy preference service receives an identification of a principal associated with a first computing device using a network connection. The network based energy preference service receives a selection of preferences from the principal associated with the first computing device over the network connection to form a set of preferences for the principal. In response to receiving a request for a subset of preferences from the set of preferences for the principal from a preference requesting service, the network based energy preference service retrieves the subset of preferences from the set of preferences by the network based energy preference service and sends the subset of preferences to the preference requesting service.

The control system of the present invention is provided for a hybrid vehicle with an engine and a motor, which are power sources, and a power storage unit for storing energy generated by the output from the engine and regenerative energy produced by regeneration of the motor when the vehicle decelerates. Based on monitoring the state of charge of the power storage unit, when the stored energy is discharged so that the remaining charge is decreased from an initial state of charge, which was detected when the vehicle started running, by a predetermined amount, the function of the motor is switched from the discharging of the power storage unit to the charging of the power storage unit.

PROBLEM TO BE SOLVED: To provide a controller for a hybrid vehicle which charges a battery device when the residual capacity of the battery device decreases by a prescribed amount from the initial value while the residual capacity is in a decreasing trend. SOLUTION: A controller for a hybrid vehicle is provided with a lower-limit threshold setting means S060 and an upper-limit threshold setting means S061 both of which respectively set the lower- and upper-limit thresholds of the amount of discharge of a battery from the initial residual capacity of the battery when a hybrid vehicle is started to run, a mode setting means S054 which changes the control of motor to a battery recovering trend when the residual capacity of the battery decreases to the lower-limit threshold, and a mode setting canceling means S062 which cancels the mode set by the mode setting means S054 when the residual capacity of the battery reaches the upper-limit threshold. The controller is also provided with a depth-of-discharge detecting means S063 which detects the amount of discharge of the present residual capacity from the initial residual capacity of the battery. The controller changes the threshold for discriminating the necessity/nonnecessity of support for driving engine by means of a motor in accordance with the depth of discharge.
