摘要

The emergency stop for an electrically driven wheelchair and vehicle for physically handicapped persons comprises two fiber optic sensors combined with a universal expansion of the control unit for rapid braking and cut-off of the vehicle. As the vehicle comes to a distance of 3 meters from a person or an object, its speed is limited. On arrival at a distance of less than 15 cm from an obstacle, the voltage feed is interrupted and the vehicle is placed out of action.
