Definitions

  • the present invention is directed to a control module for an auxiliary unit which can be activated based on a control of a remote vehicle control system, such as a keyless entry system which is already installed, for example as part of an original equipment, in a vehicle.
  • a remote vehicle control system such as a keyless entry system which is already installed, for example as part of an original equipment, in a vehicle.
  • Remote vehicle control systems such as keyless entry systems have become commonplace in vehicles for many years. Keyless entry systems operate to allow a vehicle operator to lock and unlock the doors of the vehicle via a remote key-chain transmitter. Many vehicles come with such keyless entry systems now as standard features from car manufacturers, that is on an "original equipment manufacturer” (OEM) basis. The consumer demand for this type of product has grown steadily and several original equipment keyless entry systems are now on the market.
  • OEM original equipment manufacturer
  • buttons which include at least two or three buttons.
  • the first two buttons are to lock and unlock the vehicle door, and a third button may be for a trunk control.
  • a fourth button which may be a panic mode button, which makes the horn and/or lights of the vehicle active when pressed.
  • remotely activated control systems can also be installed in vehicles either as original equipment or as after market equipment, for example, such as a vehicle alarm system.
  • a remote vehicle starter operates so that a vehicle operator merely pushes a button on a remote transmitter unit, and the vehicle is automatically started up. This type of device is very beneficial if a vehicle operator wishes to start a vehicle to allow the vehicle to heat up on a cold day, so that the vehicle will be warm prior to the operator actually having to get into the vehicle.
  • a vehicle window roll-up unit which operates to roll-up a window in the event that a vehicle operator forgets to roll-up an electric window, and the window roll-up unit can roll-up the window even after the vehicle has been turned off.
  • these auxiliary after market products are controlled by dedicated remote key-chain transmitters.
  • Some of these key-chain transmitters may include several buttons, one for starting the vehicle, and other buttons for keyless entry, alarm features, panic modes, or other personal security features.
  • one object of the present invention is to provide a novel control module for an auxiliary unit for a vehicle, which can be activated based on the operation of a remote system, such as keyless entry systems or alarm systems which may come as original equipment manufacture of a vehicle or as after-market products.
  • a remote system such as keyless entry systems or alarm systems which may come as original equipment manufacture of a vehicle or as after-market products.
  • One further object of the present invention is to provide such a novel control module which can be used with several types of auxiliary units, and which can be easily installed on the vehicle.
  • the novel control module of the present invention achieves its objectives by including an input which is connected to a designated wiring of a vehicle which is activated based on a control by an already installed, for example original equipment manufacturer, remote vehicle control unit such as a keyless entry system or alarm system.
  • a detector detects if this designated wiring is triggered at least twice within a predetermined period of time. Further, in the present invention the auxiliary unit is activated when the detector determines that the designated wiring has been triggered at least twice within the predetermined period of time.
  • Such a device of the present invention may find particular application in devices such as remote vehicle starters and window roll-up units. Further, such a device of the present invention may typically be connected to the door unlock or door lock wiring of a vehicle.
  • control module 10 which is connected to a designated vehicle wiring 5. Furthermore, the control module 10 operates to control an auxiliary unit 20, which may be a remote vehicle starter or a window roll-up unit, as examples only.
  • auxiliary unit 20 which may be a remote vehicle starter or a window roll-up unit, as examples only.
  • control module 10 is shown as a separate unit from auxiliary unit 20, although the control module 10 also can typically be formed as an integral unit within the auxiliary unit 20.
  • the present invention has an operation as follows, and as is shown in Figure 2.
  • the control module 10 initially determines if the vehicle wiring is triggered once, see step S32. If the vehicle wiring has been triggered once, the control module 10 then determines if the vehicle wiring is triggered again within a predetermined period of time, which for example may be four seconds, see step S34. If the vehicle wiring has been triggered twice within this predetermined period of time, then the auxiliary unit is triggered, see step S36.
  • the vehicle wiring 5 should be a specific vehicle wiring which is triggered based on a control of an already installed, for example original equipment manufacturer, remotely activated vehicle control system, such as a vehicle alarm system or a keyless entry system.
  • vehicle control system such as a vehicle alarm system or a keyless entry system.
  • the most common examples of the vehicle wiring 5 will be the door lock or unlock wiring of the vehicle, as typical original equipment manufacturer keyless entry systems have lock and unlock activation buttons which trigger the lock and unlock wirings of a vehicle.
  • the vehicle wiring 5 it is possible for the vehicle wiring 5 to include other wirings which are also activated by the already installed remotely activated vehicle control system, for example original equipment manufacturer, keyless entry systems or alarm systems, such as the trunk or light wirings.
  • the auxiliary unit 10 can be triggered based on a control of the already installed remotely activated vehicle control system, for example original equipment manufacturer keyless entry system or alarm system, and thus the auxiliary unit 20 does not require its own dedicated remote transmitter.
  • a remotely activated vehicle control system such as a keyless entry system
  • the vehicle wiring 5 may typically be the door lock or unlock wirings of a vehicle.
  • the auxiliary unit 20 may typically be a remote vehicle starter, which operates to remotely start a vehicle when triggered, or may be a window roll-up unit, which rolls up a window when triggered, or any other type of remote vehicle control unit.
  • FIG. 3 Shown in Figure 3 is a specific implementation of the control module 10 of the present invention, which is shown as a demonstrative example of circuitry which can be utilized to implement the control module 10 of the present invention.
  • the circuitry to implement the control module 10 of the present invention features units 4538A and 4538B, which form a dual "one shot" equivalent circuit, which for example may be model number MC145B manufactured by SGS Thomson Microelectronics.
  • the +T trigger input of 4538A receives the input from the vehicle wiring (e.g. the door lock or unlock wiring) through resistor R1.
  • Two diodes D1 and D2 are connected between resistor R1 and the +T input, diode D1 also being connected to the +12V of the vehicle and the diode D2 also being connected to ground.
  • a capacitor C1 which is further connected to ground.
  • a further resistor R2 is connected to the point between resistor R1 and the +T input, which is also connected between either +12V or ground.
  • Both sides of the 4538A and 4538B are set up to recognize a same positive trigger from the vehicle wiring input at the +T input.
  • the actual input from the vehicle wiring can either be positive or negative going based on whether the resistor R2 is connected to the +12V or ground. If resistor R2 is connected to ground, the one shot equivalent 4538A and 4538B will recognize a leading edge of a positive going trigger from the vehicle wiring input. Conversely, if resistor R2 is connected to +12V, the one shot equivalent 4538A and 4538B will recognize a negative edge of a negative going trigger of the vehicle wiring input.
  • Resistor R1 and capacitor C1 operate to bounce filter the vehicle wiring input. Diodes D1 and D2 operate as a clamp to clamp the input signal at a desired level. Typical values of R1, R2 and C2 may respectively be 1K ⁇ , 100 K ⁇ and .1F, as examples only.
  • circuit 4538A When a trigger is detected at the +T input of circuit 4538A from the vehicle wiring input, the circuit 4538A responds with a positive output pulse of approximately 4 seconds at its Q output. This Q output, which is connected to the reset pin of circuit 4538B, forces this reset pin RST of 4538B high, which readies circuit 4538B to respond to an input trigger at its own input +T. Since this reset RST of 4538B was not forced high earlier, the initial trigger input to circuit 4538A does not initially trigger circuit 4538B. Connected between the Q output of 4538A and the reset of 4538B is a resistor R5 in parallel with a capacitor C5.
  • Resistor R5 and capacitor C5 operate as a low pass filter which prevents a voltage from appearing too quickly on the reset RST of circuit 4538B, and thus does not allow circuit 4538B to respond to the initial trigger.
  • Typical values of R5 and C5 may be 100K ⁇ and .1F, as examples only.
  • circuit 4538B responds to the second trigger and produces a negative output pulse of approximately a 4 second duration at its Q ⁇ output.
  • circuit 4538A Also connected to the RXCX input of circuit 4538A is a resistor R3, which is also connected to the +12V. Connected between resistor R3 and the input RXCX at one point, and to input CX at a second point, is a capacitor C2, which is also connected to ground. The RXCX and CX inputs control the duration of the output pulse from circuit 4538A based on the values of capacitor C2 and resistor R3. A similar circuit is also formed with respect to circuit 4538B. Typical values of R3, R4 and C2, C3 are 1M ⁇ and 4.7F, as examples only.
  • the Q ⁇ output of 4538B is then fed to a timer 555, which for example may be model number TLC555C manufactured by National Semiconductor Corp., through a capacitor C4. Connected to a point between the capacitor C4 and the input to the timer 555 is also a parallel connection of a diode D3 and a resistor R6, which are also connected to +12V. Typical values for C4 and R6 are .01F and 10K ⁇ , as examples only.
  • the TR input which is the trigger input of the timer 555, is connected to an input trigger disable through diodes D4 and D5. Connected to a point between diodes D4 and D5 and between ground are also resistor R7 and capacitor C5.
  • the input trigger disable input to the TR input is a disable signal which prevents the timer 555 from triggering when a +12V is applied to this trigger disable, and for approximately two seconds after the +12 voltage is removed. This can be utilized to prevent detecting noise at a time other than when the actual desired signal is being input.
  • Typical values for R7 and C5 are 1M ⁇ and 2.2F, as examples only.
  • the TH input which is a threshold level setting input, is also connected to the D input, which is a discharge pin. Also connected to the D input is a capacitor C6, which is also connected to ground, and resistor R8, which is also connected to +12V.
  • Typical values of C6 and R8 are .1 ⁇ F and 4.7 ⁇ , as examples only.
  • the timer 555 When the output Q ⁇ of 4538B goes high, the timer 555 is activated through input TR to output a positive output pulse of approximately 400 ms, or any other fixed duration. This output pulse is then input into a base of transistor T1, which in turn supplies a negative going output trigger for the external auxiliary unit 20, which is connected to an output of the transistor T1. Also connected to the base of transistor T1 are resistors R9, R10. Also connected to the output of transistor T1 is a parallel connection of resistor R11 and R12. Typical values for R9, R10, R11 and R12 are 10K ⁇ , 10K ⁇ , 1K ⁇ and 10 ⁇ , as examples only.
  • circuitry shown in Figure 3 operates to output a negative going output trigger which is fed to the auxiliary unit 20 when the vehicle wiring 5 is triggered twice within the predetermined, e.g. 4 second, interval.
