An operating system for a standby generator includes a control unit, a switch, an inverter, a terminal, a current sensor, a starter circuit, a power control circuit, and an ignition kill circuit. The control unit is powered by a rechargeable twelve volt DC battery. The switch is selectively operable by the control unit to connect one of a first input or a second input to an output. The second input receives the supply of electrical power from an internal combustion engine. The inverter is positioned between the DC battery and the first input, and supplies electrical power to the electrical device when a movable contact of the switch connects the output to the first input. The power control circuit is connected to the control unit and is operable to adjust the movable contact of the switch to selectively connect the output to either the first input or the second input.

A system and method for controlling air conditioning and ISG systems for a vehicle are provided. The system includes a heater controller that detects a defrost mode selection signal or an A/C blower operation signal and transmits the signal to a cluster controller. The cluster controller then transmits the defrost mode selection signal or the A/C blower operation signal to an engine ECU. The engine ECU determines ISG entry prevention or ISG release after ISG entry in response to receiving the defrost mode selection signal or the A/C blower operation signal from the cluster controller.

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.

An engine control device applied to a vehicle equipped with an actuator for changing a suspension property of the vehicle, a suspension control device for driving the actuator, and an engine. The engine control device automatically stops the engine operation when a stop condition is satisfied and automatically starts the engine operation when a start condition is satisfied, continues the engine operation when a signal for inhibiting the automatic stop of the engine operation is sent to the engine control device in order to drive the actuator and the engine control device judges that no malfunction occurs in the suspension control device even if the stop condition is satisfied, and ignores the signal and automatically stops the engine operation when the stop condition is satisfied and judges that the malfunction occurs in the suspension control device even if the signal is sent to the engine control device.

What is described is a system for controlling an engine of a vehicle. The system includes a gear shifter having a gear selection sensor configured to determine a selected gear position. The system also includes a proximity sensor configured to detect object data within a predetermined area of the vehicle. The system also includes a controller coupled to the gear shifter and the proximity sensor and configured to control the engine based on the selected gear position and the object data.

A method for operating a generator for an internal combustion engine of a vehicle having a starting operating mode and a start-stop operating mode, a torque of the generator being delimited in the starting operating mode, including: detecting an operating mode of the vehicle, and deactivating a delimitation of the torque of the generator if the detected operating mode corresponds to the start-stop operating mode.

A vehicle control apparatus includes an engine configured to drive a vehicle; a starter configured to start the engine; a headlamp configured to radiate light in front of the vehicle; a battery configured to supply driving electric power to the starter and the headlamp; a brightness detection unit configured to detect a physical quantity corresponding to brightness around the vehicle; and a control unit configured to have the engine stop automatically when a predetermined stopping condition is satisfied, and to have the engine start automatically when a predetermined starting condition is satisfied. The control unit inhibits the engine from stopping automatically when the headlamp is lighted, and the physical quantity detected by the brightness detection unit is less than or equal to a predetermined threshold.

An exemplary pump condition response method includes, in response to a pump condition, operating an engine to discontinue or prevent a first stop-start cycle during a drive cycle. The method permitting a second stop-start cycle during the drive cycle.
