In one embodiment, a utility vehicle includes a plurality of ground-engaging members configured to contact a ground surface, and a powertrain assembly operably coupled to the ground-engaging members. The utility vehicle also includes a frame supported by the ground-engaging members and extending along a longitudinal axis of the utility vehicle. The utility vehicle further includes a tunnel member coupled to the frame and extending along the longitudinal axis. The tunnel member is positioned at a first height from the ground surface. Additionally, the utility vehicle includes a cargo portion supported by the frame and positioned generally rearward of the tunnel member. The cargo portion has a cargo surface substantially aligned with the tunnel member and positioned at a second height from the ground surface. The first height is approximately equal to the second height.

Provided are a method and apparatus for controlling rollover prevention of a tank truck, a cloud, a tank truck, and a system for controlling rollover prevention of a tank truck. The method includes: obtaining vehicle information sent by the tank truck and liquid filling information obtained based on a sensor; inputting the vehicle information and the liquid filling information into a vehicle fine model and a liquid sloshing fine model respectively, and outputting a first parameter calibration result and a second parameter calibration result respectively; and transmitting the first parameter calibration result and the second parameter calibration result to the tank truck, determining a control target of the tank truck by combining vehicle state sensor information observation and liquid related sensor information observation, and controlling the rollover prevention of the tank truck based on the control target.
