Abstract

A travel mode switching device for a vehicle is provided, which is switchable between a plurality of travel modes including a sport travel mode and a towing travel mode. The device includes a travel mode selection interface that allows a driver to select one of the travel modes, a towing detection sensor that detects a towing state, and a processor configured to execute a travel mode switching module to switch the travel mode to the travel mode selected by the travel mode selection interface, and a travel mode regulating module to regulate the selection of the sport travel mode by the travel mode selection interface when the towing state is detected by the towing detection sensor, and regulate the selection of the towing travel mode by the travel mode selection interface when the towing state is not detected.

First claim

What is claimed is:

1. A travel mode switching device for a vehicle, configured to be switchable between a plurality of travel modes including a normal mode, a sport travel mode, and a towing travel mode, comprising:
a travel mode selection interface that allows a driver to select one of the travel modes;
a towing detection sensor that detects a towing state;
a processor configured to execute:
a travel mode switching module to switch the travel mode to the travel mode selected by the travel mode selection interface; and
a travel mode regulating module to regulate the selection of the sport travel mode by the travel mode selection interface when the towing state is detected by the towing detection sensor, and regulate the selection of the towing travel mode by the travel mode selection interface when the towing state is not detected; and

a display unit that displays on a display screen an operation screen of the selectable travel modes, wherein
the travel mode selection interface allows the driver to select one of the travel modes on the operation screen,
the travel mode regulating module regulates so that, when the towing state is detected by the towing detection sensor, the normal mode and the towing travel mode are displayed as the selectable travel modes, and the sport travel mode is not displayed on the operation screen, and
the travel mode regulating module regulates so that, when the towing state is not detected by the towing detection sensor, the normal mode and the sport travel mode are displayed as the selectable travel modes, and the towing travel mode is not displayed on the operation screen.

2. The travel mode switching device of claim 1 , wherein the travel mode includes other travel modes excluding the normal mode, the sport travel mode, and the towing travel mode.

3. The travel mode switching device of claim 2 , wherein the other travel modes include an off-road travel mode.

4. A display unit of a travel mode switching device for a vehicle, the travel mode switching device configured to be switchable between a plurality of travel modes including a normal mode, a sport travel mod; and a towing travel mode, the travel mode switching device including a travel mode selection interface that allows a driver to select one of the travel modes and a towing detection sensor that detects a towing state, the display unit comprising:
a display screen that displays an operation screen of the travel modes selectable by the travel mode selection interface,
wherein the display unit is regulated by a processor configured to execute a travel mode regulating module so that, when the towing state is detected by the towing detection sensor, the normal mode and the towing travel mode are displayed as the selectable travel modes, and the sport travel mode is not displayed on the operation screen, and so that, when the towing state is not detected, the normal mode and the sport travel mode are displayed as the selectable travel modes, and the towing travel mode is not displayed on the operation screen.

5. The travel mode switching device of claim 4 , wherein the travel mode includes other travel modes excluding the normal mode, the sport travel mode, and the towing travel mode.

6. The travel mode switching device of claim 5 , wherein the other travel modes include an off-road travel mode.
