Abstract
A vehicle capable of an extraordinary mode of motorized motion programmed to draw the attention of an operator. When one or more sensors sense a condition requiring attention of the operator, a periodic acceleration is superposed upon the motion of the ground-contacting members. The extraordinary mode of locomotion may include a mode where the vehicle alternates between braking and speeding up and braking over each period of the modulation
Claims7
An alarm system for alerting the operator of a vehicle having a motorized drive, the alarm system comprising:
- a. a sensor for sensing a specified condition of the vehicle;
- and
- b. a controller for causing the vehicle, in response to the specified condition, to be accelerated with a vehicle acceleration modulated with a periodic modulation such that the vehicle acceleration alternates between braking and speeding up and braking over each period of the modulation.
A method for alerting a rider of a vehicle to a condition requiring attention, the method comprising:
- a. sensing a specified condition of the vehicle;
- and
- b. accelerating the vehicle, in response to the specified condition, with a vehicle acceleration modulated with a periodic modulation such that the vehicle acceleration alternates between braking and speeding up and braking over each period of the modulation.
