Abstract
A vehicle and associated method of operating a vehicle having an engine, a user interface configured to select a start-stop mode, and a controller communicating with the engine and the user interface automatically shutdown and restart the engine, and inhibit the automatic engine shutdown or restart responsive to any of a first group of inhibitors, or alternatively, any of the first group and a second group of inhibitors depending on the start-stop mode selected via the user interface.
Claims17
A vehicle comprising:
- an engine;
- and
- a start-stop system configured to control automatic stopping and restarting of the engine responsive to a first category of operating conditions when operating in a first start-stop mode, and both the first category of operating conditions and a second category of operating conditions when operating in a second start-stop mode, wherein one of the start-stop operating modes is selected responsive to input from a vehicle user interface, and wherein the start-stop system is inhibited from shutting down the engine in response to a third operating mode selected responsive to the input from the vehicle user interface.
A method of operating a vehicle engine start-stop system, comprising:
- initiating one of first and second start-stop modes;
- by a controller:
- inhibiting engine shutdown when operating in the first start-stop mode only in response to a first plurality of predetermined operating conditions;
- and
- inhibiting engine shutdown when operating in the second start-stop mode in response to the first plurality or a second plurality of predetermined operating conditions different from the first plurality, wherein initiating one of the first and second start-stop modes comprises detecting, by the controller, predetermined atypical manipulation of vehicle driving controls.
A vehicle comprising:
- an engine;
- a user interface configured to select a start-stop mode an accelerator pedal;
- a brake pedal;
- and
- a controller communicating with the engine and the user interface and configured to automatically shutdown and restart the engine, and to inhibit automatic engine shutdown or restart responsive to any of a first group of inhibitors, or alternatively, any of the first group and a second group of inhibitors depending on the start-stop mode selected via manipulation of the accelerator pedal, or the brake pedal.
