Ignition bypass system
First Claim
1. A system for controlling operation of an engine and an accessory drive of a vehicle, the system comprising:
- an ignition switch for controlling the operation of the engine that enables the engine to operate when the ignition switch is in an ON state;
a user-activated secondary switch for making a connection in a parallel electrical power supply circuit to the engine and vehicle accessory drive when the secondary switch is in the CLOSED state,a control logic circuit responsive to the ignition switch, the secondary switch, and a user-activated vehicle control device; and
a third switch associated with a user-activated vehicle control device wherein the third switch causes the control logic circuit to interrupt the parallel electrical power supply circuit when the third switch is closed, andwherein the secondary switch remains in the CLOSED state during and after actuation of the user-activated vehicle control device.

Abstract
A system and method for bypassing the ignition switch and controlling operation of an engine and an accessory drive of a vehicle, the system comprising an ignition switch, a user-activated secondary switch, a control logic circuit, and a third switch. The ignition switch controls operation of the engine that enables the engine to operate when the ignition switch is in an ON state. The user-activated secondary switch makes a connection in a parallel electrical power supply circuit to the engine and vehicle accessory drive, when the secondary switch is in the CLOSED state. The control logic circuit is responsive to the ignition switch, the secondary switch, and a user-activated vehicle control device. The third switch is associated with a user-activated vehicle control device wherein the third switch causes the logic circuit to interrupt the parallel electrical power supply circuit, when the user-activated vehicle control device is activated.

13. A method for controlling operation of a vehicle, wherein the vehicle comprises a passenger compartment, a vehicle accessory device, an engine, a logic circuit a user-activated vehicle control device, a starter motor and an electrical power supply, comprising:
-
switching an ignition key switch to an ON position when the vehicle engine is running, wherein electrical power is supplied to the engine and the vehicle accessory drive; activating a secondary switch to a CLOSED state to establish via the logic circuit a parallel electrical power supply path to the engine and vehicle accessory drive, wherein the logic circuit comprises a first device and a second device, wherein the first device provides an electrical signal to the second device causing the second device to close contact terminals for providing a parallel electrical power supply path to the engine and vehicle accessory drive, the secondary switch remaining closed during and after the user-activated vehicle control device is actuated; removing a key from the ignition key switch by switching the ignition key switch to an OFF position; and leaving the passenger compartment unoccupied with the engine running and electrical power supplied to the engine and vehicle accessory drive. - View Dependent Claims (14, 15, 16, 17)

18. A system for controlling the operation of an engine and an accessory drive of a vehicle, the system comprising:
-
an ignition switch for controlling operation of the engine that enables the engine to operate when the ignition switch is in an ON state; a user-activated vehicle control device; a user-activated secondary switch for making a connection in a parallel electrical power supply circuit to the engine and vehicle accessory drive, said user-activated secondary switch remaining closed during and after the user-activated vehicle control device is actuated; a logic circuit responsive to the ignition switch, the secondary switch, and the user-activated vehicle control device; and a third switch associated with the user-activated vehicle control device wherein the third switch causes the logic circuit to interrupt the parallel electrical power supply path, the logic circuit comprising a first relay and a second relay, wherein the first relay causes the the contacts of the second relay to open, thereby interrupting the parallel electrical power supply path when the user-activated vehicle control device is activated. - View Dependent Claims (19, 20)
