Abstract
A motorized wheelchair is advantageously provided with a rate-of-turn feedba ck sensor and with forward/reverse motion, lateral motion, and vertical motion acceleration feedback sensors that are integrated into a closed-loop wheelchair servo control system to differentially control the rotational spe ed of wheelchair opposed motor-driven wheels and thereby obtain improved wheelchair motion stability through reduction/elimination of likely wheelcha ir spin-out and wheelchair tipping during wheelchair operation.
