Patent ES-8204672-A1 (ES)
Title: Automatic speed control system.
IPC: G05D13/62
Filed: 1981-08-07
Abstract: An automatic speed control system is disclosed in which an error signal Ve, representing the speed error of the vehicle, is added to a ramp voltage, ramping between fixed values, to produce a control signal Vc. Two comparators compare Vc with upper and lower limits, respectively, so as to produce a pulse train on one of two lines depending on the sign of the error and having a mark-space ratio depending on the magnitude of the error. A circuit responds to the first pulse to occur in the pulse train from one of the two comparators when the vehicle is accelerating towards and overshooting a new desired speed and, via a switching circuit, lowers the upper limit applied to that comparator so as to lengthen the first pulses and help to reduce overshoot of the desired speed. When the vehicle ceases accelerating, the upper limit is switched back to the desired value, and is also switched back to its original setting when the speed falls by a preset amount.

Patent ES-8600134-A1 (ES)
Title: Slip limitation control for rail vehicles.
IPC: B60L3/10
Filed: 1984-09-26
Abstract: A method and device for slip-limiting control on a rail vehicle wherein for controlling or limiting slip, it is necessary to determine the actual speed of the rail vehicle. The invention overcomes the problems in traction vehicles such as, for example, locomotives which only have driving wheels and no running wheels, especially if all driving wheels slip simultaneously. For the accurate determination of the vehicle speed, the traction motor current for the associated motor is reduced for a short period, of about 3 s, at the driving wheel which is rearmost in the direction of motion, by means of a slip-reduction signal which is supplied to a slip-limiting controller which also reduces the speed of this driving wheel so that this wheel no longer slips and its peripheral wheel speed is equal to the vehicle speed. During a presettable long-term period of about 25 s, all slip-limiting controllers of the rail vehicle are preset with a speed reference signal (vref) having a slight rise in speed so that the peripheral wheel speed of the driving wheel is somewhat greater than the vehicle speed but not great enough for the wheels to spin. A jolt detector is provided for intializing this measure.
