An idle stop-start control method includes initiating a monitoring system, determining if the engine is running, and monitoring the engine to detect a shut-down condition or a sustain condition. The method includes initiating the restarting of an engine based on the condition of input parameters.

대표청구항 ▼

1. A method of starting and shutting down an engine of a vehicle during use thereof to conserve energy, the method comprising the steps of:monitoring a plurality of vehicle operating conditions, including a number of times within a preselected time interval that the engine has been shut down;setting an engine shut-down indicator whenever each of the plurality of vehicle operating conditions is acceptable;setting an engine sustain indicator whenever any one of the plurality of vehicle operating conditions is unacceptable;determining whether or not the engine is running;shutting down the engine whenever the engine is running and the shut-down indicator is set; andstarting the engine whenever the engine is not running and the engine sustain indicator is set. 2. The method of claim 1 wherein the plurality of vehicle operating conditions includes engine running temperature. 3. The method of claim 2 wherein the engine running temperature is acceptable when greater than about 170° F. and less than about 240° F. 4. The method of claim 1 wherein the plurality of vehicle operating conditions includes vehicle velocity. 5. The method of claim 4 wherein a velocity of zero is acceptable. 6. The method of claim 1 wherein the plurality of vehicle operating conditions includes a coasting condition. 7. The method of claim 1 wherein the plurality of vehicle operating conditions includes a current transmission gear. 8. The method of claim 7 wherein current transmission gear is acceptable whenever vehicle transmission is in a forward gear. 9. The method of claim 1 wherein the plurality of vehicle operating conditions includes service brake status. 10. The method of claim 9 wherein service brake depression is acceptable. 11. The method of claim 1 wherein the plurality of vehicle operating conditions includes load conditions of engine accessories. 12. The method of claim 11 wherein any accessory high load condition is unacceptable. 13. The method of claim 1 wherein the plurality of vehicle operating conditions includes vehicle electrical system status. 14. The method of claim 13 wherein a normal vehicle electrical system status is acceptable. 15. The method of claim 1 wherein the engine comprises an internal combustion engine. 16. The method of claim 1 wherein the engine comprises a hybrid combination of electrical and internal combustion energy sources. 17. The method of claim 1 further comprising initiating power-up of the vehicle and waiting for a predetermined period of time prior to the step of monitoring. 18. A system for starting and shutting down an engine of a vehicle during use thereof to conserve energy, the system comprising:a vehicle engine controller; anda plurality of sensors for monitoring a plurality of vehicle operating conditions, including a number of times within a reselected time interval that the engine has been shut down, the sensors coupled to the vehicle engine controller;the engine continuer operative to shut down the engine whenever the engine is running and each of the plurality of sensors indicates an acceptable operating condition, andthe engine controller operative to start the engine whenever the engine is not running and any one of the plurality of sensors indicates an unacceptable operating condition. 19. The system of claim 18 wherein the plurality of sensors includes at least one of the following:an engine temperature sensor;a speedometer;a gear sensor;a brake pedal position sensor;an accessory load sensor; andan electrical system sensor.
