STARTER SYSTEM HAVING CONTROLLING RELAY SWITCH
A starter system including a motor, a solenoid assembly having a solenoid switch, a pinion rotated by the motor and moveable into an engaging position in which an engine may be cranked and the solenoid switch is closed to energize the motor from an electric power source, and relay switch regulated by a controller and closed to apply electrical power to the solenoid assembly for actuating the solenoid switch. The controller repeatedly opens and closes relay switch during a starting operation if sensed motor energization voltage monitored by the controller falls below a predetermined threshold level within a predetermined time period after electrical power is applied to the solenoid assembly, whereby electrical power applications to the solenoid assembly are automatically repeated during a starting operation to correct “click-no-crank” events and prevent prolonged power application to the solenoid assembly. A related method is also disclosed.
POWER DELIVERY APPARATUS
A power delivery apparatus (100) for a vehicle includes an upstream delivering portion (10) and a downstream delivering portion (20). The upstream delivering portion (10) includes: an internal input terminal (11); an external input terminal (12); and a connecting terminal (13). The internal input terminal (11), the external input terminal (12) and the connecting terminal (13) are different terminals from one another. The downstream delivering portion (20) includes: a connected terminal (23); a fuse portion (22a-22e) connected to the connected terminal (23); and a downstream output terminal (21a-21e) outputting the electric power via the fuse portion (22a-22e). The upstream delivering portion (10) and the downstream delivering portion (20) are independent members each other and are assembled to be integrated with each other to allow connecting the connecting terminal (13) and the connected terminal (23).
Engine start-up device, and engine-start-up control method
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.
Engine start control device
An engine start control device is provided with: a starter relay that is provided between a battery and a starter motor; a start abnormality determining means that determines the occurrence of start abnormality of an engine; and a start control means, which turns on the starter relay, and starts supplying power from the battery to the starter motor in the cases where a start instruction signal is inputted from a start switch, and which turns off the starter relay in the cases where the start abnormality determining means determined the occurrence of start abnormality of the engine.
AIRCRAFT STARTING AND GENERATING SYSTEM
An aircraft starting and generating system includes a starter/generator and an inverter/converter/controller that is connected to the starter/generator and that generates AC power to drive the starter/generator in a start mode for starting a prime mover of the aircraft, and that converts AC power, obtained from the starter/generator after the prime mover have been started, to DC power in a generate mode of the starter/generator. A four leg inverter is coupled with the DC power output and has an inverter/converter/controller (ICC) with a four leg MOSFET-based bridge configuration that drives the starter/generator in a start mode for starting a prime mover of the aircraft, and converts DC power to AC power in a generate mode of the starter/generator. A four leg bridge gate driver is configured to drive the four leg MOSFET-based bridge using pulse width modulation (PWM) during start and generate mode.
