Self-adaptive wheelchair obstacle avoidance control system

The invention discloses a self-adaptive wheelchair obstacle avoidance control system, and relates to the field of automatic control systems. The obstacle avoidance system comprises a control module, a plurality of obstacle avoidance modules and conversion and pulse width adjustment circuits correspondingly connected with the obstacle avoidance modules, the obstacle avoidance modules are connected with a microcontroller module through the conversion and pulse width adjustment circuits, a direct current motor and a motor driving module receive control signals transmitted by a single chip microcomputer, and the motor driving module controls the rotating speed of a motor. Therefore, the movement of the wheelchair is accurately controlled; the single chip microcomputer control module analyzes road condition information in real time according to the received information and sends an instruction to the motor driving module by adopting a proper control algorithm according to the information so as to control the movem
