System and method for adjusting air flow in an engine compartment of an off-road vehicle
First Claim
1. An air flow control system for an off-road vehicle, comprising:
- a first movable side panel configured to be positioned proximate to a first lateral side surface of a body of an engine hood of the off-road vehicle; and
a controller configured to;
receive a signal indicative of a temperature of an engine of the off-road vehicle;
access a desired engine temperature range from a storage device;
output a first control signal to instruct one or more actuators to move the first movable side panel laterally outward relative to the first lateral side surface of the body of the engine hood to enable a flow of air through a gap between the first movable side panel and the body of the engine hood when the first signal indicates that the temperature of the engine of the off-road vehicle is greater than the desired engine temperature range during operation of the engine;
output a second control signal to instruct the one or more actuators to move the first movable side panel to a closed position in response to shut-down of the engine of the off-road vehicle;
receive an operator input to close the first movable side panel via an input device; and
output a third control signal to instruct the one or more actuators to move the first movable side panel to a rear-facing open position in response to receipt of the operator input to close the first movable side panel while the signal indicates that the temperature of the engine of the off-road vehicle is greater than the desired engine temperature range during operation of the engine, thereby blocking debris and facilitating air flow under the engine hood, and wherein a rearward portion of the first movable side panel is positioned a first distance laterally outward from the first lateral side surface of the body of the engine hood and a forward portion of the first movable side panel is positioned a second distance, less than the first distance, laterally outward from the first lateral side surface of the body of the engine hood when the first movable side panel is in the rear-facing open position.

Abstract
An air flow control system for an off-road vehicle includes a first movable side panel configured to be positioned proximate to a first lateral side surface of a body of an engine hood of the off-road vehicle. The system also includes a controller configured to receive a first signal indicative of a temperature of an engine of the off-road vehicle, to access a desired engine temperature range from a storage device, and to output a third signal to one or more actuators indicative of instructions to move the first movable side panel laterally outward relative to the first lateral side surface of the body to enable a flow of air through a gap between the first movable side panel and the body when the first signal indicates that the temperature of the engine of the off-road vehicle is greater than the desired engine temperature range.

8. An air flow control system for an off-road vehicle, comprising:
-
a first movable side panel configured to be positioned on a first lateral side of a body of an engine hood of the off-road vehicle; one or more bars extending laterally inward from the first movable side panel, wherein the one or more bars are configured to couple the first movable side panel to the body of the engine hood, and the one or more bars are telescoping bars comprising a stationary portion fixedly coupled to the body of the engine hood and an adjustable portion configured to slide relative to the stationary portion, wherein the one or more bars comprise at least one forward bar positioned proximate to a forward edge of the first movable side panel and at least one rearward bar positioned proximate to a rearward edge of the first movable side panel; and one or more actuators coupled to the one or more bars and configured to move the adjustable portion of the one or more bars and the first movable side panel laterally outward relative to the first lateral side of the body of the engine hood in response to one or more signals from a controller of the air flow control system, wherein the at least one forward bar is coupled to a first actuator of the one or more actuators and the at least one rearward bar is coupled to a second actuator of the one or more actuators. - View Dependent Claims (9, 10, 11, 12)
