Abstract
Operation of a vehicle air conditioner is delayed during engine starting. Switching of an ignition switch 16 to a START position is sensed by a detecting circuit 10, causing contacts 22, 24 of a first relay 14 to close thereby energising a delay circuit 30. A transistor 42 in the delay circuit 30 turns on after an adjustable delay set by a R-C circuit 37, 38, 40. An SCR 44 is turned on by the transistor 42 resulting in operation of a second relay 46 and closure of relay contact 52, whereby a wire 56 coupled to the air conditioner is connected to an accumulator 19 via contacts 22, 52 of the first and second relays 14, 46.
Description
TITLE:VEHICLE ELECTRICAL CONTROL SYSTEM
BACKGROUND OF THE INVENTION
The invention relates to an electrical control system. More particularly, the invention relates to a vehicle electrical control system.
When an air condition of a vehicle is turned off before an engine is actuated, an accumulator will consume a large amount of electricity while the engine is actuated. Under certain situations, the engine may not be actuated.
SUMMARY OF THE INVENTION
An object of the invention is to provide an electrical control system which can delay a short period of time to provide an electricity for an air conditioner of a vehicle while an engine is actuated.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an electrical schematic view of an electrical control system of a preferred embodiment in accordance with the invention; and
FIG. 2 is an electrical schematic view of another electrical circuit which is not controlled by an electrical control system of a preferred embodiment.
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, an electrical control system comprises a detecting circuit 10 and a delay circuit 30.
The detecting circuit 10 is connected to an electrical switch 16. The delay circuit 30 is connected to the detecting circuit 10. The detecting circuit 10 has a first diode 12, a first relay 14, a cathode point 15 of the first diode 12 connected to the first relay 14 and the electrical switch 16, an anode point 17 of the first diode 12 connected to an indicator 18, the first relay 14 has a first normal on point 20 and a first common joint point 24 connected to an accumulator 19. The first diode 12 and the first relay 14 are in series. The indicator 18 indicates whether a dynamotor is actuated.
The delay circuit 30 has a first wire 32 connected to the cathode point 15 of the first diode 12, a second wire 34 connected to the first common joint point 24, a second diode 36, a current-limiting resistor 37, a variable resistor 38, a capacitor 40, a transistor 42, a resistor 48, a silicon controlled rectifier 44, a second relay 46, a first normal off point 22, a second normal on point 52, a second normal off point 50, a third wire 54 and a fourth wire 56.
The electrical switch 16 has a START position, an ON position, an ACC position, and a LOCK position. When a key turns on the electrical switch 16 to the ON position, the ACC position, or the LOCK position, the first common joint point 24 will switch from the first normal off point 22 to the first normal on point 20. Then the delay circuit 30 cannot form a loop circuit. When the key turns on the electrical switch 16 to the START position, the indicator 18 is extinguished so that the first relay 14 is not in operation. Then the first common joint point 24 will switch from the first normal on point 20 to the first normal off point 22. The accumulator 19 provides a negative voltage to the second wire 34, and the electrical switch 16 provides a positive voltage to the first wire 32. Then the delay circuit 30 forms a loop circuit.
The variable resistor 38 and the capacitor 40 charge a period of time until a predetermined voltage value is reached to actuate the transistor 42. A current flows through the resistor 48 to provide a positive voltage to a gate 45 of the silicon controlled rectifier 44 to actuate the silicon controlled rectifier 44 and the second relay 46. The second relay 46 will switch from the second normal off point 50 to the second normal on point 52. Then the negative voltage passes through the third wire 54 and the positive voltage passes through the fourth wire 56 to an air conditioner. Thus the electrical control system can delay a short period of time to provide the electricity for the air conditioner of a vehicle while an engine is actuated.
Referring to FIG. 2, another electrical circuit is not controlled by the electrical control system so that some electric devices need not be controlled by the electrical control system. The electrical circuit has a manual switch 58, a relay 60 and a plurality of electric devices such as lights. When the manual switch 58 is turned on, the relay 60 is actuated so that a common joint point 63 will switch from a normal off point 62 to a normal on point 64. The electrical circuit is connected to an accumulator via a wire 57 and another wire 66 so that the accumulator can provide an electric power to the electric system of the vehicle.
