Engine control for vehicle using electronic key system
First Claim
1. A control device for an engine of a vehicle, the engine comprising an operating device which operates the engine under an electronic key system comprising a portable electronic key which emits an identification code, and an identification device mounted in the vehicle to verify the identification code of the electronic key, the control device comprising:
- a programmable controller programmed to;
control the operating device to execute an idle stop which stops the engine under a predetermined stop condition;
control the operating device to restart the engine during the idle stop when any of a plurality of restart conditions are satisfied, the restart conditions including a restart request from a driver of the vehicle;
determine whether or not the engine is in the idle stop;
determine whether or not a restart condition is satisfied which does not correspond to a restart request from the driver during an idle stop;
control the identification device to verify the identification code of the electronic key when a restart condition is satisfied which does not correspond to the restart request from the driver during the idle stop; and
prohibit the operating device from restarting the engine when the identification device has failed in verifying the identification code.

Abstract
An engine (1) of a vehicle comprises an identification device (11) which verifies the identification code of an electronic key (12) using a wireless signal. The controller (5) executes an idle stop under predetermined stop conditions (S6, S7) and re-starts the engine (1) during the idle stop when any one of a plurality of restart conditions are satisfied. The restart conditions include a restart request from the driver of the vehicle (S6, S7). The controller (7) commands the identification device (11) to verify the identification code of the electronic key (12) when restart conditions are established which do not correspond to the restart request to the engine (1) of the driver during an idle stop. When the verification is unsuccessful, restarting of the engine (1) is prohibited and thus it is possible to prevent restarting the engine (1) when the driver is not present.

11. A control device for an engine of a vehicle, the engine comprising an operating device which operates the engine under an electronic key system comprising a portable electronic key which emits an identification code, and an identification device mounted in the vehicle to verify the identification code of the electronic key, the control device comprising:
-
means for controlling the operating device to execute an idle stop which stops the engine under a predetermined stop condition;
means for controlling the operating device to restart the engine during the idle stop when any of a plurality of restart conditions are satisfied, the restart conditions including a restart request from a driver of the vehicle;
means for determining whether or not the engine is in the idle stop;
means for determining whether or not a restart condition is satisfied which does not correspond to a restart request from the driver during an idle stop;
means for controlling the identification device to verify the identification code of the electronic key when a restart condition is satisfied which does not correspond to the restart request from the driver during the idle stop; and
means for prohibiting the operating device from restarting the engine when the identification device has failed in verifying the identification code.

12. A control method for an engine of a vehicle, the engine comprising an operating device which operates the engine under an electronic key system comprising a portable electronic key which emits an identification code, and an identification device mounted in the vehicle to verify the identification code of the electronic key, the control method comprising:
-
controlling the operating device to execute an idle stop which stops the engine under a predetermined stop condition;
controlling the operating device to restart the engine during the idle stop when any of a plurality of restart conditions are satisfied, the restart conditions including a restart request from a driver of the vehicle;
determining whether or not the engine is in the idle stop;
determining whether or not a restart condition is satisfied which does not correspond to a restart request from the driver during an idle stop;
controlling the identification device to verify the identification code of the electronic key when a restart condition is satisfied which does not correspond to the restart request from the driver during the idle stop; and
prohibiting the operating device from restarting the engine when the identification device has failed in verifying the identification code.
