Abstract
A system for automatically leveling a wheelchair access device is provided. The system may comprise a sensor configured to ascertain an angle of a platform of the wheelchair access device in at least one direction, a controller configured to receive a signal from the sensor, and a regulator configured to adjust at least one setting of a power source configured to operate the wheelchair access device. The controller may be programmed to execute logic based on the signal received and send a signal to the regulator to adjust the setting accordingly. The system may additionally include an indicator configured to notify the operator of the wheelchair access device.
