摘要： The purpose of the present invention is to swiftly start up an engine in a range in which electrical equipment having electric power supplied thereto by a battery is not reset, even in cases when the battery is insufficiently charged and the battery is deteriorated. An engine start-up device according to the present invention starts up an engine by transmitting, to the engine, the rotary force of a direct-current motor driven by a battery. The engine start-up device is provided with: a battery-voltage acquisition unit for acquiring the battery voltage of the battery; a target-current-value calculation unit which calculates, on the basis of the battery voltage acquired by the battery-voltage acquisition unit, a target current value for a motor current to be supplied from the battery to the direct-current motor; and a motor-current control unit for controlling a switching element which is connected to the direct-current motor, and through which the motor current flows, such that the motor-current value of the motor current approaches the target current value.

摘要： A vehicle propulsion system includes an engine configured to be selectively activated to provide torque to propel the vehicle and a starter module coupled to the engine and configured to start the engine from an inactive state. The starter module includes a brushless electric machine to generate an output torque to crank start the engine. The starter motor also includes a pinion gear coupled to the electric machine, where the pinion gear is actuatable to selectively engage a cranking input of the engine. A controller assembly is programmed to cause actuation of the pinion gear to engage the cranking input of the engine and transfer a cranking torque to activate the engine.

摘要： An idling stop device installed in a vehicle includes a microcomputer, a detector, a storage, and a controller. The microcomputer automatically stops an engine of the vehicle when a prescribed stopping condition is satisfied, and automatically activates a starter motor of the engine when a prescribed activating condition is satisfied. The detector detects whether a drive voltage of the microcomputer, which is obtained by dropping a voltage of a battery of the vehicle is less than a threshold value. The storage stores, irrespective of a state of the microcomputer, information indicating that the detector has detected that the drive voltage is less than the threshold value. The controller drops an increasing speed of a current for driving the starter motor when the microcomputer activates the stator motor under the condition that the information is stored in the storage.

摘要： An engine starter system includes a current switching device for controlling an armature current, a shorting relay for electrically shorting the current switching device, and an electronic control circuit. In a normal starting mode, the electronic control circuit gradually increases the armature current by varying a duty ratio of the current switching device. When the armature current becomes larger than an allowable current value of the current switching device, an armature is energized through the shorting relay. In an economy-running starting mode, the armature current is controlled through the current switching device until the engine is completely started.
