<p>PURPOSE:To accurately stop a vehicle at a regular position with good riding feeling by varying the deceleration of the vehicle from a point isolated at the prescribed distance from the regular point along a secondary curve. CONSTITUTION:Information that a vehicle arrives at a deceleration control starting ground point is fed through a zone transmission line and an energization controller to a central control unit at the moment that a vehicle arrives at a deceleration control starting ground point. The central control unit immediately calculates the speed V0 of the vehicle, and reads out the time t0 by the speed. Then, the central control unit calculates the maximum deceleration betamax and a brake force F1, where W is the weight of the vehicle, by formulae ( I ), (II), and flows a current corresponding to the brake force to a trolley wire. The brake force F2 after the t0 seconds is elapsed upon transferring to the deceleration control is calculated by a formula (III), and the current of the trolley wire is controlled until the vehicle stops. In this manner, the vehicle is accurately stopped to the regular point with good riding feeling.</p> |
