Abstract:     An automatically balancing vehicle having a headroom monitor. The headroom monitor determines the difference between the maximum velocity of the vehicle and the present velocity of the vehicle. An alarm receives a signal from the headroom monitor and produces a warning when the headroom falls below a specified limit.

First Claim:
Show all 7 claims		 What is claimed is:     1. A vehicle for carrying a payload including a user, the vehicle comprising:
  • a. a platform which supports the user;
  • b. a ground-contacting module, to which the platform is mounted, which propels the user in desired motion over an underlying surface;
  • c. a motorized drive arrangement, coupled to the ground-contacting module; the drive arrangement, ground-contacting module and payload comprising a system being unstable with respect to tipping when the motorized drive is not powered; the motorized drive arrangement causing, when powered, automatically balanced operation of the system wherein the vehicle has a present velocity and a maximum operating velocity, determined by a requirement of acceleration to maintain balance and, in operation, has a balancing margin determined by the difference between the maximum operating velocity and the present velocity of the vehicle;
  • d. a balancing margin monitor, coupled to the ground-contacting module, for generating a signal characterizing the balancing margin; and
  • e. an alarm, coupled to the balancing margin monitor, for receiving the signal characterizing the balancing margin and for warning when the balancing margin falls below a specified limit.
