Problems solved by technology

[0005] However, in Patent Document 1, a specific detection method of the battery voltage is not disclosed, and a method for more accurately determining the state of charge of the battery is not studied.
In addition, no study has been conducted on the case where, when the detected battery voltage is low and the engine is restarted, whether or not the battery is sufficiently charged is considered as a condition for allowing the idling stop control to be performed again after the restart.

Abstract

The invention provides an idling stop controller, which can appropriately prevent accumulator from achieving the overdischarging status in the idling stop control by correctly detecting the charging state of the accumulator. The idling stop controller has an idling stop controlling mechanism and a charging state detection mechanism. When the prescribed condition is satisfied, the idling stop controlling mechanism executes the idling stop control to stop the engine, and in the control, the engine is stated when the starting up operations are detected; the charging state detection mechanism detects the charging state of the accumulator. In the idling stop control, the idling stop controlling mechanism determines whether the charging state of the accumulator is suitable for the status controlled by the idling stop, based on the load voltage detected by the connection of the accumulator and the ACG startup motor. The connection of the accumulator and the ACG startup motor is performed in short time of irrotational degree of the motor. When it is not suitable to the controlled status, the standby indicating lamp emits alarm or restarts the engine.

Description

technical field [0001] The present invention relates to an idling stop control device, in particular to an idling stop control device which stops an engine when a predetermined condition is satisfied and restarts the engine according to a starting operation. Background technique [0002] Conventionally, there is known an idling stop control device that stops the engine of a vehicle when a predetermined condition is satisfied, and restarts the engine when a start operation is detected during the engine stop. Since this idling stop control is assumed to be executed when the car is temporarily stopped due to waiting for a signal, etc., the power supply to various electrical loads (such as auxiliary machinery such as headlights) is set to continue even during idling stop control. supply. Therefore, as the idling stop control time elapses, the battery is discharged, and if the battery reaches an overdischarged state, there is a possibility that the engine cannot be restarted. T...
