摘要： An image of an elevator hall or an inside of elevator car is acquired by photographing apparatus, and the number of waiting passenger is detected by comparing the above-mentioned image with a background image when no passenger is present at the elevator hall. Second image processing apparatus with high precision is prepared by the same image information as that of first image processing apparatus, teacher information derived therefrom is compared with an output from the first image processing apparatus. If the teacher information is not coincident with the output from the first image processing means, parameters required for performing the image process by the first image processing appartus, for instance, constants, threshold values and weight coefficients employed in an image processing algorithm are adjusted.

摘要： The commencement of a developing period of slip is detected by the fact that a time-differential value v.sub.s of a creep velocity v.sub.s (a relative velocity between a peripheral velocity v.sub.m of a driving wheel and a vehicle velocity v.sub.t) exceeds a predetermined reference .delta..sub.1. The termination of the developing period is detected by the fact that a time-differential value v.sub.m of the peripheral velocity v.sub.m becomes equal to zero. During the developing period, a torque command Tp to a main motor controller is decreased by a re-adhesion control signal Tfa which is formed by the combination of a time-dependent component e.sub.1 and a slip-dependent component e.sub.2. After termination of the developing period, the torque command Tp is decreased with time at an appropriate time constant. According to the present invention, the arithmetic logic operation for control can be much simplified without any deterioration of a adhesion performance of an electric vehicle.
