摘要： PROBLEM TO BE SOLVED: To solve the problem in the methods and apparatuses for controlling the speed of electric three-wheelers in which, since the up-hill grade and the down-hill grade of the road surfaces are detected using an inclination angle sensor, fixing parts therefor must be also considered in the inventory of parts, this is one of factor for increase of cost. SOLUTION: Deceleration characteristics, corresponding to the speed when brakes are applied, are extracted from a deceleration characteristic table before decelerating operation. Changes in speed at a certain time, after the application of the brakes, is extracted. Based on the variation in speed, deceleration characteristics are re-extracted from the above deceleration characteristic table before carrying out decelerating of a drive motor.

摘要： PROBLEM TO BE SOLVED: To provide a highly reliable rotor position detecting device at a low cost without using a detecting means such as an encoder in an embedded magnet type synchronous motor. SOLUTION: Exciting current of particular frequency is run through an exciting winding 13 for rotor position detection, using the exciting winding 13 for rotor position detection and rotor position detecting windings 10, 11 and 12, which are wound around a rotor, to detect induced voltage of the rotor position detecting windings 10, 11 and 12. The mutual inductance of the exciting winding 13 for rotor position detection and the rotor position detecting windings 10, 11 and 12 is changed with the position of the rotor, so that the induced voltage of the rotor position detecting windings 10, 11 and 12 changes for rotor position information. It is thus possible to constitute a rotor position detecting device with windings which can detect the rotor position from the induced voltage of the rotor position detecting windings 10, 11 and 12 and can be used in the resting condition of a rotor, thus providing high reliability and cost reduction.

摘要： PURPOSE:To prevent a chopper circuit form overheating by restricting an input voltage of the circuit when the temperature of the circuit becomes the prescribed value or higher. CONSTITUTION:Since a bimetal switch 29 is closed when a power transistor 17 for forming a chopper circuit is the prescribed temperature or lower, a control transistor 25 is interrupted. Accordingly, a pulse signal in response to an input voltage Vin from an accelerator circuit 18 is applied to the transistor 17. When the temperature of the transistor 17 becomes the prescribed value, the switch 29 is opened to conduct the transistor 25. Therefore, an input voltage Vin of an operational amplifier 23 reduced to lengthen the OFF time of a pulse signal output from a PWM modulator 35. Thus, the heat of the transistor 17 is suppressed.

摘要： PURPOSE:To prevent a current overshoot at starting time while obtaining sufficient stability and adaptability by providing a varying limiter for limiting the variation amount of conduction rate. CONSTITUTION:A feedback controller 13 outputs a feedback conduction rate alpha2 in response to a deviation DELTAI between an armature current command value IC and an armature current 1A. A damping controller 14 subtracts the differentiated value of the current IA by the differentiated value of a capacitor voltage EC and outputs a damping conduction rate alpha3. A feed-forward controller 12 outputs a feed-forward conduction rate alpha1 in response to an armature speed VLC and a filter capacitor voltage EC. A varying limiter 15 limits the varying rate of the conduction rate alpha0 added with conduction rates alpha1-alpha3 to the prescribed value C1 or lower and outputs an armature chopper conduction rate alpha.

摘要： PURPOSE:To simply alter a plurality of patterns of the relationship between the opening of an accelerator and the conduction rate and acceleration data by storing in advance the patterns in a memory of a controller. CONSTITUTION:Switches SW1-SW6 of a data selector 9 are selected before closing a key switch 5, and a pattern of the relationship between the opening of an accelerator and the conduction rate and a cushion starting characteristic pattern stored in the memory of a controller 10 are selected. When a key switch 5 is closed, the controller 10 starts operating, and controls the conduction rate of a chopper 3 in response to the depressing stroke of an accelerator 11 on the basis of the selected pattern. Thus, desired feeling can be altered simply.

摘要： PURPOSE:To stabilize a speed by taking in currents flowing through a motor when a chopper is turned ON-OFF, calculating average currents and controlling the electric rolling stock. CONSTITUTION:A micro-computer 1 is constituted by a microprocessor 2, a RAM3, a ROM4, an oscillator 5 and a bus line 6. An analog input circuit 7 converts analog electric signals ACA corresponding to the quantity of an accelerator device 8 stepped on and analog signals obtained by passing detecting signals under the state of operation of a main circuit 10 through a level converting circuit 11 into digital signals and takes them in. An interruption circuit 14 and the flow-rate control circuit 15 of the chopper determine ON time during one period, i.e. a duty. The square waves of the output are divided into ON pulses and OFF pulses by a pulse distributing circuit 16. These pulse signals are amplified 17, and used as chopper signals in the main circuit 10. Accordingly, the currents flowing through the motor are taken in when the chopper is turned ON-OFF, average currents are calculated, and the electric rolling stock is controlled.
