Vehicle leveling systems, devices and methods and computer program products for leveling vehicles using smart devices

A method for leveling a recreational vehicle, the method comprising:

• sensing an inclination of the recreational vehicle in both a pitch direction and a roll direction when the recreational vehicle is parked on an uneven surface of the ground;
• based on the sensed inclination of the recreational vehicle, determining adjustment pairs, each adjustment pair including a height adjustment amount and a corresponding adjustment direction needed to level a respective section of the recreational vehicle by movement of the respective section of the recreational vehicle with respect to the uneven surface of the ground by the height adjustment amount in the corresponding adjustment direction;
• displaying at least one image, representative of the recreational vehicle and showing the respective sections of the recreational vehicle, on a display screen of a smart device;
• simultaneously displaying the height adjustment amount and corresponding adjustment direction of each adjustment pair on the display screen adjacent to each respective section of the recreational vehicle in the at least one image;
• and
• updating the display screen, essentially in real time, as the height adjustment amounts are changed.

A non-transitory computer readable medium comprising computer executable instructions that, when executed by a processor of a smart device, control the smart device to perform steps comprising:

• receiving a pitch angle measurement and a roll angle measurement of a vehicle from a sensor device secured to the vehicle when the vehicle is parked on an uneven surface of the ground;
• based on the pitch angle measurement and roll angle measurement, calculating adjustment pairs, each adjustment pair include a height adjustment amount and a corresponding adjustment direction needed to level the vehicle by movement of the respective section of the vehicle with respect to the uneven surface of the ground by the height adjustment amount in the corresponding adjustment direction;
• and
• displaying, on a display screen of the smart device, at least one image representative of the vehicle and showing the respective sections of the recreational vehicle;
• simultaneously displaying, on the display screen of the smart device, the height adjustment amount and corresponding adjustment direction of each adjustment pair adjacent to each respective section of the vehicle in the at least one image;
• and
• updating the display screen of the smart device, essentially in real time, as the height needed to adjust the vehicle to level the vehicle changes.
