Abstract
The present application describes a method of controlling a vehicle, wherein the vehicle comprises a hybrid powertrain including an electric propulsion system, an engine and a drivetrain that is configurable in a low-range mode or a high-range mode. The method comprises determining whether the low-range mode for the drivetrain is selected, determining whether an electric mode for the powertrain is selected, and inhibiting operation of the engine if both the low-range mode and the electric mode are selected.
Claims18
A method of controlling a vehicle, the vehicle comprising a hybrid powertrain including an electric propulsion system, an engine and a drivetrain that is configurable in a low-range mode or a high-range mode, the method comprising:
- determining whether the low-range mode for the drivetrain is selected by a user;
- determining whether an electric mode for the powertrain is selected by the users;
- determining a selected vehicle driving mode of a plurality of different vehicle driving modes, wherein the vehicle driving mode is configured to optimize vehicle operating parameters for a particular terrain;
- when the vehicle is in a first subset of the different vehicle driving modes, inhibiting operation of the engine if both the low-range mode and the electric mode are selected by the user, and
- when the vehicle is in a second subset of the different driving modes that is different from the first subset, permitting operation of the engine when both the low-range mode and the electric mode are selected by the user.
A control system for a vehicle, the vehicle comprising a hybrid powertrain including an electric propulsion system, an engine and a drivetrain that is configurable in a low-range mode or a high-range mode, the control system comprising a processing module configured to:
- determine whether the low-range mode for the drivetrain is selected by a user;
- determine whether an electric mode for the powertrain is selected by the user;
- determine a selected vehicle driving mode of a plurality of different vehicle driving modes, wherein the vehicle driving mode is configured to optimize vehicle operating parameters for a particular terrain;
- when the vehicle is in a first subset of the different vehicle driving modes, inhibit operation of the engine if both the low-range mode and the electric mode are selected by the user;
- and
- when the vehicle is in a second subset of the different driving modes that is different from the first subset, permit operation of the engine when both the low-range mode and the electric mode are selected by the user.
