This application claims the benefit of Taiwan Patent Application No. 097140902, filed on Oct. 24 2008 , which is hereby incorporated by reference for all purposes as if fully set forth.

BACKGROUND OF THE INVENTION

Field of Invention

The present invention relates to a control system, and more particularly to a vehicle starter control system which, when starting a vehicle, temporarily disconnects non-activated specific loads of the vehicle in order to facilitate starting the vehicle engine.

Related Art

The rapid development in science and technology and the demands of living have brought about the gradual increase in auxiliary electronic equipment on vehicles. However, this also means that, when starting a vehicle, the storage battery must provide greater electric power to simultaneously start the vehicle engine and the loads additionally installed on the vehicle, such that the electronic equipment can therefore be used after starting the vehicle.
Referring to FIG. 1, which shows a schematic view of a motorcycle starter system of the prior art, and as depicted in the drawing, a starter system for a general motorcycle is provided with a storage battery 10 and a key switch 11 used to control whether the storage battery 10 is switched on or not, a start switch 12 and a brake connecting switch 13. When these switches have been simultaneously activated to establish electric conduction, then a motor 14 of the motorcycle utilizes electric conduction caused by an electromagnetic effect of a motor relay 15 electrically connected to the motor 14 to establish an electric connection with the motor 14, thereby causing the motor 14 to start running and to actuate an engine 16 of the motorcycle. However, at the same time electric conduction is established with the motor 14, the storage battery 10 needs to additionally provide electric power to supply a load 17 electrically connected to the motor relay 15. Hence, under circumstances whereby power must be supplied to the motor 14 and the load 17, then problems of voltage drop in the storage battery 10 and inability to smoothly start the engine 16 will occur.
From the aforementioned it can be known that an increase in electronic equipment has brought about the need for the storage battery 10 to additionally provide electric power to the load 17 when starting the motorcycle, thereby making it even more difficult to start the engine 16. Under such circumstances, apart from creating inconvenience for the rider, the long cumulative effect will result in damage to the electronic devices of the motorcycle starter system..

SUMMARY OF THE INVENTION

The objective of the present invention lies in providing a vehicle starter control system which, when starting a vehicle, first temporarily disconnects related non-activated specific loads (such as lamps, radiator fan of the vehicle) from the vehicle starter system in order to facilitate starting the vehicle engine.
According to the aforementioned objective, the vehicle starter control system of the present invention comprises a power unit for supplying electric power, a main switch connected to the power unit and used to control whether or not the power unit supplies electric power and a start switch electrically connected to the main switch, a motor relay, which is switched on by turning on the main switch and the start switch, and an electrically actuated motor, an engine set into operation by the motor, a generator which generates electric power once the engine is running, and an ignition device which controls ignition of the engine. Wherein, the vehicle starter control system is also provided with at least one switching switch, which, after turning on the main switch and the start switch to establish electric conduction, enables temporarily disconnecting electric power from non-activated specific loads, such as the headlight, radiator fan, and the like, which are installed on the vehicle, thereby enabling the power unit to have sufficient electric power to actuate the motor so as to start the engine. Moreover, when the start switch has not been activated, the power unit is able to supply power to the load.
From the aforementioned it can be known that disposition of the switching switch enables, when starting the vehicle, first temporarily disconnecting the non-activated specific loads from the starter system, thereby enabling the power unit to have sufficient electric power to start the motor so as to easily start the engine.

The ignition device 24 is used to control ignition of the engine 27. The motor relay 25 is electrically connected to the main switch 21, the start switch 22, the motor 23, the ignition device 24 and the motorcycle load 29 is connected in series to the ignition device 24, wherein the load 29 of the motorcycle is an electronic equipment which is often installed on motorcycles, such as the headlight, light bulbs, LED lamps, even a water cooled or air cooled radiator fan, and the like. The switching switch 26 is a relay, and the switching switch 26 is electrically connected to one end of the load 29. Moreover, when starting the motorcycle, the switching switch 26 is used to temporarily electrically disconnect the load 29 from the control system.
When a rider turns on the main switch 21, and simultaneously presses the start switch 22 (producing a conducting state), then the storage battery 20 is able to provide electric power to the control system and causes the motor relay 25 to switch into conduction. Moreover, through use of a special configuration, after switching into conduction, as a result of an electromagnetic effect, the switching switch 26 is electrically connected to the load 29 is transformed from an original normally closed connection a into a normally open connection b, thereby temporarily electrically disconnecting the load 29 of the motorcycle from the control system, and enabling the storage battery 20 to provide sufficient electric power to first actuate the motor 23 so as to start the engine 27. Furthermore, at the same time the engine 27 is started, the start switch 22 is in an OFF position, at which time the switching switch 26 loses the electromagnetic effect and returns to the original normally closed connection a from the normally open connection b, thereby enabling the load 29 to reestablish an electrical connection with the control system. After which, ignition control of the engine 27 is carried out through the ignition device 24 to actuate the motorcycle and enable forward movement thereof.
Referring together to FIG. 2B and FIG. 3, in which FIG. 2B is a schematic view depicting a second embodiment of the vehicle starter control system according to the present invention, and FIG. 3 is a schematic view of FIG. 2B using a lamp as the load.

After power is turned-on, the motor 34 is used to bring the engine 37 into operation, whereupon running of the engine 37 simultaneously drives the DC or AC generator 39 joined to the engine 37 to generate electric power, and the electric power produced by the generator 39 is stored in the storage battery 30 to supply the control system for use thereof. The ignition device 38 is used to control ignition of the engine 37. The motor relay 35 is electrically connected to the main switch 31, the start switch 32, the brake connecting switch 33, the motor 34, the ignition device 38, and the motorcycle load 40 is connected in series to the ignition device 38, wherein the load 40 of the motorcycle is an electronic equipment which is often installed on motorcycles, such as the headlight, light bulb, an LED lamp 400 (as depicted in FIG. 3), even a water cooled or air cooled radiator fan, and the like. The switching switch 36 is a relay, and the switching switch 36 is electrically connected to one end of the load 40.

Moreover, through use of a special configuration, after electrical conduction, as a result of an electromagnetic effect, the switching switch 36 is electrically connected to the load 40 is transformed from an original normally closed connection a into a normally open connection b, thereby temporarily electrically disconnecting the load 40 of the motorcycle from the control system, and enabling the storage battery 30 to provide sufficient electric power to first actuate the motor 34 so as to start the engine 37. Furthermore, at the same time the engine 37 is started, the start switch 32 and the brake connecting switch 33 are in an OFF position, at which time the switching switch 36 loses the electromagnetic effect and returns to the original normally closed connection a from the normally open connection b, thereby enabling the load 40 to reestablish an electrical connection with the control system. After which, ignition control of the engine 37 is carried out through the ignition device 38 to actuate the motorcycle and enable forward movement thereof.
Referring to FIG. 4, which shows a flow chart for the vehicle start control method of FIG. 2B according to the present invention, From the drawing it can be seen that when electrical conduction has been established through the main switch 31, the brake connecting switch 33 and the start switch 32 (step S 100, step S110 and step S120), then an electrical connection of the load 40 of the motorcycle to the control system is temporarily disconnected by the switching switch 36 (step S130), at which time the storage battery 30 is able to provide sufficient electric power. And switching into conduction of the motor relay 35 (step S 140) is used to first start the motor 34 (step S 150), and after step S 130 and step S150 are completed, then the ignition device 38 is used to control ignition of the engine 37, whereupon the engine 37 starts running (step S160).
