Prime mover RPM limiting control
First Claim
1. A method for controlling the operation of a vehicle prime mover based on the engagement status of one or more safety restraints of the vehicle, said method comprising:
- monitoring, via a RPM controller of the vehicle, an operational status of the vehicle;
monitoring, via the RPM controller, an engagement status of at least one passenger safety restraint of the vehicle; and
limiting, via the RPM controller, a rotational speed of one or more prime mover of the vehicle to a maximum threshold when the vehicle is in an On operational status and the at least one safety restraint is in a disengaged status,wherein limiting the rotational speed of the one or more prime mover to the maximum threshold comprises controlling, via the RPM controller, operation of a throttle of at least one of the one or more prime mover, and wherein controlling the operation of the throttle of the at least one of the one or more prime mover, comprises overriding, via the RPM controller, a throttle command received from an accelerator pedal of the vehicle so that the rotational speed of the one or more prime mover does not exceed the maximum threshold regardless of the throttle command received from an accelerator pedal.

Abstract
A method for controlling the operation of a vehicle prime mover based on the engagement status of one or more safety restraints of the vehicle. In various implementations the method comprises monitoring, via a RPM controller of the vehicle, an operational status of vehicle, monitoring, via the RPM controller, the engagement status at least one passenger safety restraint of the vehicle, and limiting, via the RPM controller, a rotational speed, e.g., revolutions per minute (RPM) of one or more prime mover of the vehicle when the vehicle is in a On operational status and the at least one safety restraint is in a disengaged status.

6. A method for controlling the operation of a vehicle prime mover based on the engagement status of one or more safety restraints of the vehicle, said method comprising:
-
monitoring, via a RPM controller of the vehicle, an operational status of the vehicle; monitoring, via the RPM controller, an engagement status of at least one passenger safety restraint of the vehicle; monitoring, via the RPM controller, a presence of a vehicle passenger in a seating structure of the vehicle, and limiting, via the RPM controller, a rotational speed of one or more prime mover of the vehicle when the vehicle is in an On operational status, the at least one safety restraint is in a disengaged status, and at least one passenger is present in the seating structure.

7. An off-road utility vehicle, said vehicle comprising:
-
a pair of front wheels and a pair of rear wheels operationally connected to a chassis of the vehicle; a passenger compartment supported by the chassis, the passenger compartment comprising; a vehicle operational status switch structured and operable to control the operational status of the vehicle; at least one seating structure structured and operable to support one or more vehicle passenger; and at least one safety restraint device, each safety restraint device structured and operable to retain a respective vehicle passenger in a respective seating structure; a drivetrain operationally connected to at least one of the wheels, the drivetrain comprising one or more prime mover structured and operable to generate torque deliverable to the at least one of the wheels; and a prime mover RPM controller, the prime mover RPM controller structured and operable to; receive input from the vehicle operational status switch of the vehicle to monitor an operational status of the vehicle; receive input from at least one safety restraint sensor of the vehicle to monitor an engagement status of the at least one passenger safety restraint; and output commands to one or more prime mover to limit a rotational speed of the one or more prime mover of the vehicle to a maximum threshold when the vehicle is in an On operational status and the at least one safety restraint is in a disengaged status. - View Dependent Claims (8, 9, 10, 11, 12, 13)
