First Claim
Patent Images
1. A recreational vehicle including:
- a chassis;
a ground engaging member configured to support the chassis;
a power source supported by the chassis, the power source including at least one of an engine and an electric motor;
a transmission including at least one of a continuously variable transmission and a hydrostatic transmission, the transmission being driven by the power source and having an adjustable gear ratio;
a sub-transmission coupled to the transmission, the sub-transmission having a plurality of selectable gear configurations including a forward gear and at least one of a park gear, a reverse gear, and a neutral gear;
an actuator operative to change a gear configuration of the sub-transmission;
a shift device including a signal output operative to provide a shift request signal indicative of a request to change the gear configuration of the sub-transmission; and
a controller including at least one processor, the controller being operative to control the gear ratio of transmission and being in communication with the shift device and the actuator, the controller being operative to control the actuator to change the gear configuration of the sub-transmission in response to detecting the shift request signal provided by the shift device.

Abstract
A recreational vehicle is provided including a power source, such as an engine or an electric motor, and a transmission having a variable gear ratio. A sub-transmission coupled to an output of the transmission includes a plurality of selectable gear configurations including at least one of a forward gear, a neutral gear, a reverse gear, and a park gear. An electronic controller is operative to electronically control the gear configuration of the sub-transmission.

20. A method of controlling a sub-transmission of a recreational vehicle, the method including:
-
controlling, by a controller of the vehicle, an output speed of a power source of the vehicle, the power source including at least one of an engine and an electric motor, the controller including at least one processor; controlling, by the controller, a gear ratio of a transmission of the vehicle, the transmission including at least one of a continuously variable transmission and a hydrostatic transmission, the transmission being driven by the power source; detecting, by the controller, a shift request signal provided by a shift device, the shift request signal indicating a request to shift a sub-transmission of the vehicle to a target gear configuration, the sub-transmission being driven by an output of the transmission and having a plurality of selectable gear configurations including a forward gear and at least one of a park gear, a reverse gear, and a neutral gear; and controlling, by the controller, an actuator to change a gear configuration of the sub-transmission to the target gear configuration based on the shift request signal. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A non-transitory computer-readable medium comprising:
executable instructions such that when executed by at least one processor cause the at least one processor to; control an output speed of a power source of a vehicle, the power source including at least one of an engine and an electric motor; control a gear ratio of a transmission of the vehicle, the transmission including at least one of a continuously variable transmission and a hydrostatic transmission, the transmission being driven by the power source; detect a shift request signal provided by a shift device, the shift request signal indicating a request to shift a sub-transmission of the vehicle to a target gear configuration, the sub-transmission being driven by an output of the transmission and having a plurality of selectable gear configurations including a forward gear and at least one of a park gear, a reverse gear, and a neutral gear; and control an actuator to change a gear configuration of the sub-transmission to the target gear configuration based on the shift request signal. - View Dependent Claims (33, 34, 35, 36, 37)
