Abstract: A planetary gear train transmission device of a hybrid vehicle is provided, which belongs to the technical field of transmissions. A transmission device of a hybrid vehicle based on a planetary gear train, which has a simple structure and is convenient to maintain is provided. The transmission device is composed of two motors, two clutches, one simple planetary gear train, and one complex planetary gear train. One motor is mainly used for generating power, and the other motor is used for driving the vehicle to move forward and brake to recover energy. Selection of different speed ratios and different working modes can be achieved by means of different combinations of the clutches and the planetary gear trains and different working states of the engine and the two motors. The present disclosure is convenient to control, has a compact structure, and adopts a few of parts.

Abstract: Apparatus and associated methods relate to a programmable resistor having a resistance iteratively programmed by a calibration control loop. In an illustrative example, the calibration control loop may alternately sample the programmable resistance and a reference resistance by producing a corresponding voltage drop across the resistors. The voltage drops may, for example, be induced by the same constant current source. The calibration control loop may compare the voltage drops with a comparator, for example. In some examples, the comparator may provide a count direction signal to a logic block, generating a calibration code. The calibration code may, for example, be applied to the programmable resistor, such that the resistance of the programmable resistor iteratively approaches the resistance of the reference resistor.
