  • Patent number: 10632860
    Abstract: A vehicle for a controller includes an electronic control unit which includes an alternator that can generate electric power using rotation of an engine and a first battery and a second battery that can be charged by the alternator. The first battery is connected in parallel to the alternator and the second battery is connected in parallel to the alternator and the first battery via a second switch. The electronic control unit is configured not to charge the second battery with regenerative power generated by the alternator by switching the second switch to an OFF state when the temperature of the alternator is higher than a first predetermined value.

  • Patent number: 10415529
    Abstract: There is provided a controller for a vehicle that can execute, while the vehicle is stationary or moving, control of automatically stopping an engine upon determining that automatic stop conditions are met, and automatically restarting the engine upon determining that automatic restart conditions are met while automatic engine stop is in effect. At a time of first engine restart in one trip, the controller diagnoses whether a system that automatically restarts the engine is normal or abnormal. The automatic stop conditions for in-motion automatic engine stop include automatic stop execution conditions that are set based on a state of the vehicle, and automatic stop permit conditions that are set based on a travel environment. The controller sets the automatic stop permit conditions such that determination criteria are more stringent as a cumulative number of times of in-motion automatic engine stop in one trip is smaller.

  • Patent number: 9821811
    Abstract: An electronic control device automatically stops an engine operation when a remaining electric power amount index value is equal to or larger than an engine stop permission threshold. The device automatically restarts the engine operation when the remaining electric power amount index value is smaller than an engine restart threshold after the engine operation is automatically stopped. The device changes the engine stop permission threshold from a first threshold, which has been set until a start of an activation of an electric actuator, to a second threshold, which is larger than the first threshold, when the automatic engine stop is not carried out and the activation of the actuator is detected.

  • Patent number: 9523337
    Abstract: An idling stop control device of the invention acquires an index (SOCx) indicating a magnitude of a remaining charged electric power amount of a battery (41), restarts an operation of an engine (25) by operating a starter (43) when the index becomes smaller than a predetermined restart threshold (SOCstart) while an automatic stop of the operation of the engine has been carried out, and changes the threshold from a first threshold (SOC1) to a second threshold (SOC2) when an operation of an electric actuator (31) is started while the automatic stop has been carried out. The first threshold is a threshold set immediately before the operation of the actuator is started and the second threshold is smaller than the first threshold.

  • Patent number: 6578006
    Abstract: A work management method and system which manage a project executed by individuals or groups belonging to an organization. In response to a phase transition request from a task management unit, a workflow management unit performs transition and activation of a business phase included in a process definition, sets a work in work management table, and issues a task addition request. In response to an event addition request or a deletion request, an event management unit adds or deletes events to or from an event queue, monitors an occurrence of the event and, when the event occurs, sends a task status transition request to the task management unit. In response to the task addition request, the task management unit sets a task name and a task status name in the work management table, generates the event associated with the task name, issues the event addition request.
