Abstract
Official abstract text for this publication.
A vehicle start-stop system includes an engine and a controller. The controller is programmed to operate the system in a first mode when a first input is selected, and in a second mode when a second input is selected. The controller is further programmed to inhibit engine stop in response to being in the first mode and an evaporator temperature having a first value, and stop the engine in response to being in the second mode and the evaporator temperature having the first value.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle start-stop system comprising: an engine; and a controller programmed to: operate the system in a user-comfort mode when a first input is selected, and in an economy mode when a second input is selected, inhibit engine stop in response to being in the user-comfort mode and an evaporator temperature having a first value, stop the engine in response to being in the economy mode and the evaporator temperature having the first value, restart the engine in response to being in the user-comfort mode and the evaporator temperature having a second value, and inhibit restarting the engine in response to being in the economy mode and the evaporator temperature having the second value. 2. The start-stop system of claim 1 , wherein the controller is further programmed to restart the engine in response to being in the economy mode and the evaporator temperature having a third value that is greater than the second value. 3. A vehicle start-stop system comprising: an engine configured to automatically stop and start during travel; and a start-stop system including a user interface having first and second inputs and a controller, the controller being programmed to: operate the system in a user-comfort mode when the first input is selected, and in an economy mode when the second input is selected, inhibit engine stop in response to being in the user-comfort mode and an evaporator temperature having a first value, stop the engine in response to being in the economy mode and the evaporator temperature having the first value restart the engine in response to being in the user-comfort mode and the evaporator temperature having a second value, and inhibit restarting the engine in response to being in the economy mode and the evaporator temperature having the second value. 4. The start-stop system of claim 3 , wherein the controller is further programmed to restart the engine in response to being in the economy mode and the evaporator temperature having a third value that is greater than the second value. 5. A method of operating a start-stop system of a vehicle, the method comprising: operating the system in a user-comfort mode when a first input is selected, and in an economy mode when a second input is selected; inhibiting an engine stop in response to being in the user-comfort mode and an evaporator temperature having a first value; stopping the engine in response to being in the economy mode and the evaporator temperature having the first value restarting the engine in response to being in the user-comfort mode and the evaporator temperature having a second value; and inhibiting restarting the engine in response to being in the economy mode and the evaporator temperature having the second value. 6. The method of claim 5 further comprising: restarting the engine in response to being in the economy mode and the evaporator temperature having a third value that is greater than the second value.
