ABSTRACT:
An electronic control system for a stair climbing vehicle, such as a wheelchair is disclosed. Front and back sensors are provided for detecting a stairway or slope. The electronic control system determines from the sensor data whether the slope has an acceptable incline for traversing. If it is not acceptable, the vehicle will be prevented from entering onto the stairway or slope. A seat for a user is tilted in accordance with electronic controls to keep the user approximately vertical with respect to gravity as the vehicle traverses the stairs. The allowed operation of the vehicle is controlled via parameters which can be changed by removable memory which configures the vehicle for a particular user or group of users.
