1. A stand-up vehicle comprising:
a vehicle upper portion having a surface configured for a user to stand on;
a handrail arranged on the surface of the vehicle upper portion, the handrail configured for the user to grip;
one or more sensors configured to detect movement of the user riding on the stand-up vehicle;
a power unit configured to drive the stand-up vehicle; and
one or more electronic control units configured to control the power unit to limit a speed of the stand-up vehicle to an upper limit speed or less, wherein
the one or more electronic control units are configured to execute:
an emergency detection process to detect an emergency of the user when receiving a notification from the user or based on information from the one or more sensors;
a safety posture determination process to determine whether or not the user is in a safety posture based on information from the one or more sensors after the emergency is detected by the emergency detection process, the safety posture includes a posture in which the user stands on all fours on the surface including the user being only on their hands, knees, and feet;
an upper limit speed management process that is executed when the emergency is detected by the emergency detection process and the user is determined by the safety posture determination process to be in the safety posture, and
in the upper limit speed management process, the one or more electronic control units increase the upper limit speed to be higher than a basic upper limit speed selected when the safety posture determination process determines that the user is not in the safety posture, or cancels the upper limit speed.
