Rough terrain vehicle and storage medium

1. A rough terrain vehicle comprising:

a vehicle body;

a sensor group mounted on the vehicle body and configured to detect a state of the vehicle;

a control target mounted on the vehicle body and operable during driving of the vehicle; and

a processor mounted on the vehicle body, the processor being configured to:

estimate a margin for overturning of the vehicle or for load on the vehicle based on a result of detection by the sensor group; and

when the vehicle is traveling, control the control target to allow the estimated margin to exceed a predetermined level, wherein

the vehicle body includes an operator operable by a user,

the processor estimates the margin based on the result of detection by the sensor group and a result of acquisition of a request command indicating a requested vehicle body behavior, the request command being generated based on an operation performed by a user on the operator, and

upon determining that the estimated margin is below the predetermined level, the processor does not use the request command as a control command provided to the control target.

2. The rough terrain vehicle according to claim 1 , wherein

the request command specifies an engine speed or a throttle position,

upon determining that the margin is above the predetermined level, the processor uses the request command as the control command provided to the control target, and

upon determining that the margin is below the predetermined level, the processor does not provide the control command to the control target.

3. The rough terrain vehicle according to claim 1 , wherein

the request command specifies an engine speed or a throttle position,

upon determining that the margin is above the predetermined level, the processor uses the request command as the control command provided to the control target, and

upon determining that the margin is below the predetermined level, the processor does not use the request command as the control command provided to the control target but corrects the request command to allow the margin to exceed the predetermined level and uses the corrected request command as the control command provided to the control target.

4. The rough terrain vehicle according to claim 1 , wherein the sensor group detects a structural state of the vehicle or a state of a cargo carried on the vehicle as an indicator of the state of the vehicle.

5. The rough terrain vehicle according to claim 1 , wherein

the sensor group includes an operation amount detection sensor configured to detect an amount of the operation performed by the user on the operator, and

the processor estimates a state of a ground surface on which the vehicle is traveling based on a detection value obtained by the operation amount detection sensor and estimates the margin by using the estimated state of the ground surface.
