Eco-run control device and method for resetting the same
First Claim
1. An eco-run control device that is mounted on a vehicle and is capable of performing eco-run control to stop an engine if predetermined stop requirements are satisfied, and to restart the engine if predetermined start requirements are later satisfied, the eco-run control device comprising:
- at least one first type control unit having power supplied thereto in accordance with a state of an ignition;
at least one second type control unit having power supplied thereto in accordance with a state of an ACC;
a start control unit that, when the power supplied to the at least one first type control unit or the power supplied to the at least one second type control unit is turned from off to on, performs a start control operation on the engine if the start control unit receives an eco-run prohibiting request from the at least one first type control unit or from the at least one second type control unit;
a main relay unit that continues the power supply to the eco-run control device for a predetermined period of time even after the ignition is turned off;
a determining unit that receives an ignition state signal from a predetermined signal line and determines a state of the ignition as being off when the received ignition state signal indicates that the ignition is off, based on whether signals from at least two of the control devices of the first type are interrupted; and
a prohibiting unit that prohibits the reception of the eco-run prohibiting request even when the at least one first type control unit or the at least one second type control unit sends the eco-run prohibiting request after the ignition detection unit determines that the ignition is off, and prevents the engine from being started by the start control unit.

Abstract
An eco-run control device is mounted on a vehicle and is capable of performing eco-run control to stop an engine when predetermined stop requirements are satisfied and restart the engine when predetermined start requirements are satisfied later. This eco-run control device includes: a monitoring unit that monitors the state of an ignition; a communicating unit that communicates with a plurality of control devices that receive power supplies from a power supply line that is connected to a power source via the ignition; and an initialization controlling unit that initializes the data with respect to the eco-run control stored in a memory, when the monitoring unit determines that the ignition is in an OFF state, and that the communications with two or more of the control devices are interrupted.

9. A method for controlling an eco-run control device that is mounted on a vehicle and is capable of performing eco-run control to stop an engine if predetermined stop requirements are satisfied, and to restart the engine if predetermined start requirements are later satisfied, the method comprising:
-
performing a start control operation on the engine, when the power supplied to at least one first type control unit or the power supplied to at least one second type control unit is turned from off to on, if a start control unit receives an eco-run prohibiting request from the at least one first type control unit or from the at least one second type control unit; continuing the power supply to the eco-run control device for a predetermined period of time even after the ignition is turned off; receiving an ignition state signal from a predetermined signal line and determining the state of the ignition as being off when the received ignition state signal indicates that the ignition is off, based on whether signals from at least two of the control devices of the first type are interrupted; and prohibiting the reception of the eco-run prohibiting request even when the at least one first type control unit or the at least one second type control unit sends the eco-run prohibiting request after the ignition detection unit determines that the ignition is off, and prevents starting the engine from being started by the start control unit.
