A motor speed control apparatus includes a ladder resistor circuit, a reference signal generator, and a comparator. The ladder resistor circuit selectively receives a voltage signal having a predetermined amplitude at a plurality of nodes. The ladder resistor circuit arranged to change an output voltage value thereof in accordance with a voltage application position. The level of the reference signal generator is periodically changed. The comparator compares a voltage value of the reference signal with an output voltage value of the ladder resistor circuit and outputs a pulse output having a variable pulse width on the basis of a comparison result. A motor speed is controlled on the basis of the pulse output.

Motor speed control apparatus

In a remote control apparatus for a transmission, a gear change of a transmission is performed by auxiliary power, the auxiliary power is controlled upon change lever operation by a driver and, in case that the present selected position of the gear is different from the selecting position instructed by the change lever, the gear of the transmission is held in a neutral position for a predetermined period of time when the gear is moved from any shift position to the neutral position.

Remote control apparatus for transmission

A transmission remote control apparatus with a plurality of gear shift positions so as to shift a gear shift lever between gears through corresponding neutral positions has a diagnosis unit which has: a drive circuit for sequentially moving the gear shift lever in all neutral positions; a detector for detecting that the gear shift lever has passed all the neutral positions; an alarm generator for generating an alarm when a failure is detected; and a controller for controlling the drive circuit, the detector and the alarm generator.
