1. A remote engine starting system for starting an engine of a vehicle, the system comprising:
- a first communication device for receiving an engine start command signal transmitted from a portable transmitter held by a user;
a second communication device for receiving an engine start command signal transmitted from a transmitter provided in a vehicle key;
an engine control means for permitting and prohibiting an engine starting in response to the engine start command signal received by the first communication device or the second communication device;
a determination means for determining whether the engine is started by the engine start command signal received by the first communication device or the second communication device, when the engine is started by the engine control means; and
an indication means for indicating a vehicle travel prohibition when the engine starting is prohibited by the engine control means, the indication means providing an indication of the vehicle travel prohibition when the engine is started in response to the engine start command signal received by the first communication device without the engine start command signal received by the second communication device, and the indication means stopping the indication of the vehicle travel prohibition when the engine is started in response to the engine start command signal received by the second communication device.

Abstract
A remote engine starting system starts an engine when an engine start command signal is transmitted from a remote controller or an ignition key. The system includes an immobilizer ECU, which sets an immobilizer system to prohibit vehicle travel and drives an LED to flash to thereby indicate the vehicle travel prohibition. When the engine is started by the ignition key, the immobilizer system is unset and the LED stops the indication of the vehicle travel prohibition. When the engine is started by the remote controller, the immobilizer system is unset but the LED continues to flash to indicate the vehicle travel prohibition.

9. A remote engine starting method for a vehicle, the method comprising:
-
receiving an engine start command signal; starting an engine of the vehicle in response to the engine start command signal; determining whether the engine start command signal is transmitted at an outside of the vehicle or at an inside of the vehicle; controlling travel of the vehicle based on a determination result, so that the vehicle travel is prohibited when the determination result indicates that the engine start command is transmitted at the outside of the vehicle; and unsetting an immobilizer system of the vehicle when the engine is started in response to the engine start command signal, whether the engine start command signal is transmitted at the outside or the inside of the vehicle; and indicating prohibition of the vehicle travel, when the engine is started in response to the engine start command signal transmitted at the outside of the vehicle. - View Dependent Claims (10)

11. A remote engine starting method for a vehicle, the method comprising:
-
receiving an engine start command signal; starting an engine of the vehicle in response to the engine start command signal; determining whether the engine start command signal is transmitted at an outside of the vehicle or at an inside of the vehicle; controlling travel of the vehicle based on a determination result, so that the vehicle travel is prohibited when the determination result indicates that the engine start command is transmitted at the outside of the vehicle; and stopping the engine when a door of the vehicle is opened after the engine is started in response to the engine start command signal transmitted from the outside of the vehicle.

12. A remote engine starting system for a vehicle, the system comprising:
-
a receiver for receiving an engine start command signal; a starter for starting an engine of the vehicle in response to the engine start command signal; and a processing system for performing; determining whether the engine start command signal is transmitted at an outside of the vehicle or at an inside of the vehicle; controlling travel of the vehicle based on a determination result, so that the vehicle travel is prohibited when the determination result indicates that the engine start command is transmitted at the outside of the vehicle; unsetting an immobilizer system of the vehicle when the engine is started in response to the engine start command signal, whether the engine start command signal is transmitted at the outside or the inside of the vehicle; and indicating prohibition of the vehicle travel, when the engine is started in response to the engine start command signal transmitted at the outside of the vehicle.
