Abstract
A recreational vehicle includes a seatbelt sensor configured to detect when a seatbelt is in an engaged position or a disengaged position and an engine control module in communication with the seatbelt sensor to automatically limit a maximum speed of the vehicle to a reduced maximum speed limit upon detection of the seatbelt is in the disengaged position.
Claims18
A recreational vehicle including:
- a chassis;
- a ground engaging mechanism configured to support the chassis;
- an engine supported by the chassis;
- a throttle valve configured to regulate air intake into the engine;
- an engine control module configured to control the throttle valve;
- a user interface configured to provide a first user input to the engine control module;
- a throttle input device in communication with the engine control module;
- and
- a location detection device in communication with the engine control module, wherein the location detection device is configured to:
- detect a location of the vehicle;
- and
- provide, to the engine control module, information indicating the detected location of the vehicle;
- and
- wherein the engine control module is configured to:
- receive, from the user interface, the first user input indicating a maximum speed limit of the vehicle and a geographical area corresponding to the maximum speed limit,
- determine that the detected location of the vehicle is inside the geographical area;
- and
- control, based on the detected location of the vehicle, a modulation of the throttle valve to limit a vehicle speed of the vehicle to the maximum speed limit corresponding to the geographical area indicated by the first user input.
