A monitoring method includes, among other things, within a vehicle, providing a first electrical system with an auxiliary battery, and a second electrical system with a primary battery. The method further includes electrically coupling the first electrical system to the second electrical system, electrically loading the auxiliary battery and the primary battery, and comparing an electrical parameter of the auxiliary battery to a threshold value to assess a state of the auxiliary battery.

An assembly for an engine includes a control module including a controller operable to control at least certain aspects of the operation of the engine, a display including an input connected to the controller, and a wireless receiver connected to the controller. The wireless receiver is arranged to receive a signal from a wireless device to cause the controller to send an engine start signal to cause starting of the engine and wherein the input when actuated causes the controller to send an engine start signal to cause starting of the engine. In at least some implementations, no keyed ignition switch is provided to start the engine and the engine is started only via the wireless device or the input.

An exhaust treatment device for a diesel engine is provided, which includes a parked regeneration requirement notification component and a parked regeneration start operation component. A regeneration process of the diesel particulate filter (DPF) includes an automatic regeneration process and a parked regeneration process. The automatic regeneration process is automatically started when an estimation value of particulate material (PM) accumulated in the DPF reaches a predetermined automatic regeneration start determination value. The parked regeneration process is performed when first and a second conditions are satisfied. The first condition is that a parked regeneration requirement notification component performs a notification of a parked regeneration requirement when a number of cancellations of the automatic regeneration process reaches a predetermined value. The second condition is that the parked regeneration start operation component is subjected to a start operation during a parked state in which an engine equipped machine is neither traveling nor working.

In a vehicle control device with an automatic engine stop function, when the engine is in a non-operating state and the shift lever is operated to the parking range, the engine is controlled to start to supply operating oil to a valve timing changing means. The valve timing changing means is thereupon caused to change the intake valve close timing (IVC) to a predetermined advance angle position and subsequently locked thereat. The engine is then controlled to stop.

A method of enabling operation of an ignition system for outdoor power equipment may include monitoring status of a plurality of switches associated with respective components of the equipment where at least one of the respective components corresponds to one or more binary start fault operators, and setting a start enabling status for the one or more 5 binary start fault operators responsive to actuation of a start fault clearance operator.

A vehicle engine activation control system includes a starter connected to a battery; an idle stop control unit configured to automatically stop an engine and automatically reactivate the engine by the starter; an input unit configured to generate an operation request in response to input from a driver; an electric parking brake device including an electric motor connected to the battery, wherein the electric motor starts driving in response to the operation request; and a mediating unit configured to prohibit the reactivation of the engine by the idle stop control unit, when the electric motor is in a driving state in response to a predetermined operation request.

An idle reduction system for use with an engine can include a main unit including a controller, and a relay controlled by the controller. The relay can be electrically connected between an ignition switch and an electrical power source for starting the engine. A method of reducing idling of an engine can include connecting an idle reduction system, thereby permitting the system to shut down the engine in response to one or more predetermined conditions, the idle reduction system starting the engine in response to at least one of : a) battery voltage being less than a predetermined level, and b) engine temperature being less than a predetermined level, and the idle reduction system controlling operation of at least one of: an auxiliary air conditioner and an auxiliary heater.

A method for remotely starting a manual transmission vehicle is provided. The method includes determining whether remote start of the manual transmission vehicle is possible based on a remote start command signal of a remote start input device, an inclination angle signal value of the manual transmission vehicle, a notch signal value generated when a parking brake of the manual transmission vehicle is operated by moving a lever of the parking brake, and a gear shift stage signal of a manual transmission of the manual transmission vehicle. An engine of the manual transmission is started when the notch signal value according to the inclination angle signal value is greater than or equal to a minimum value of notch signal values capable of remotely starting the manual transmission vehicle and the gear shift stage signal is a neutral stage signal.

A vehicle includes an engine, a park assist system, a passenger detection system configured to detect at least one passenger, and a processing device. The processing device initiates a shutdown sequence when no passengers are present in the vehicle. The shutdown sequence includes commanding the park assist system to park the vehicle and turning off the engine after the vehicle is parked.

A start-stop vehicle includes an engine configured to automatically stop and start during travel. The vehicle further includes a gear lever, a brake pedal, and a controller. The controller is programmed to restart the engine or inhibit restarting of the engine depending upon one or more sets of conditions of the vehicle. A method is also present for operating the vehicle based upon the one or more sets of conditions.
