A vehicle control device controls an automatic transmission by utilizing road information stored in a navigation system unit. In response to the road information stored in a data memory, the upper-limit of a shiftable transmission speed range is determined, thereby allowing shift-change only within the restricted transmission range. The actual down-shift is carried out after confirming a decelerating operation by the driver, such as release of the accelerator pedal, thereby providing favorable transmission control in conformity with the driver's intention.

A ZnO--Pd composite catalyst wherein Pd is dispersed and fixed on the surface of ZnO is produced by ion adsorption process having the steps of soaking ZnO in an acid solution of Pd to adsorb Pd ions (Pd.sup.2+) onto the surface of ZnO; and reducing the adsorbed Pd ions to metallic Pd particles so that the metallic Pd particles are substantially evenly deposited on the surface of ZnO. The ZnO--Pd composite catalyst provides a stable and continuing CO oxidizing capability, without light irradiation, even when the air to be treated contains sulfur compounds such as H.sub.2 S and SOx.

ZnO-Pd composite catalyst and production method thereof

An air-purifying filter includes a carrier base and a TiO.sub.2 -Pd composite catalyst supported on the carrier base. CO in air treated by the filter is adsorbed onto the Pd surface and thus decomposed by oxidization to CO.sub.2, whereas sulfur compounds in the air are adsorbed onto the Pd surface and then transferred to the TiO.sub.2 surface where they are decomposed by oxidization to SO.sub.4.sup.-2 when the TiO.sub.2 is subjected to irradiation. Preferably, Pd exists in a relatively small quantity at a first side of the carrier base in the vicinity of a light source and in a greater quantity at a second side opposite the first side. The first side is preferably located upstream relative to flow of air treated by the filter. An air-purifier utilizing this filter is mounted in an automobile, preferably on a rear shelf or in a trunk compartment. The air-purifier has a light source for irradiating the filter, and an exhaust port, arranged at a position to utilize negative pressure of the automobile generated during driving, to exhaust any substances desorbed from the composite catalyst to the outside of the automobile.

A control system for a vehicular automatic transmission which detects running status of the vehicle and includes a shift controller for controlling the gear stage of the automatic transmission in accordance with the detected running status of the vehicle. The control system further includes a memory for prestoring road information for roads to be run by the vehicle, present location detection and running direction detection. A reader reads out the road information for a set route from the present location to a destination, from the memory, on the basis of the detected present location and the destination input. The engine power required for the vehicle to travel the set route is estimated in accordance with the read road information. A shift schedule which minimizes the fuel consumption on the set route is determined by comparing the estimated engine power requirement with a prestored mileage map and the shift control pattern is changed in accordance with the determined shift schedule.

Control system for vehicular automatic transmission

An apparatus for controlling an automatic transmission of an automobile and a method therefor utilize a route guidance system. The apparatus includes a memory which stores road information, a detector for detecting a specific position which is located on a planned driving route from the road information stored in the memory; a position detector for detecting the present position of the automobile; a speed detector for detecting the speed V of the automobile; a sensor for detecting an opening degree .theta. of a throttle of the automobile; a computer for computing a distance 'd' between the detected automobile position and the detected specific position; a driving operation detector for detecting an operation by the driver of the automobile; a first gear ratio selecting device for selecting a first gear ratio for the automatic transmission based on the detected speed V and the detected throttle opening degree .theta.; and a second gear ratio selecting device for selecting a second gear ratio based on the detected speed V, the distance 'd', the detected operation by the driver and the first gear ratio selected by the first gear ratio selecting device. As a result, it is possible to carry out gear change control taking anticipated changes in the driving conditions into account, thus enabling smooth and comfortable driving. Further, since the driver of the automobile can have advance voice notice of control operations, it is possible to avoid confusion caused by sudden unexpected changes.

A continuously variable transmission system includes a belt type continuously variable transmission unit which, in turn, is composed of a primary pulley and a secondary pulley wherein the torque transmitting direction is switched by torque circulation in changeover between forward and reverse travel. When a low mode is selected in a D range, a somewhat higher hydraulic pressure from a regulator valve is supplied, through a manual valve, to a secondary hydraulic servo, which moves one sheave of the secondary pulley, and a somewhat lower hydraulic pressure from a ratio control valve is supplied to a primary hydraulic servo which moves one sheave of the primary pulley. When the D range is switched to R range by the manual valve, the supplies of the above hydraulic pressures are reversed. With this arrangement, the relative axial forces on the pulleys are changed in switching between forward and reverse travel.

A 5-speed automatic transmission for a vehicle having a highly efficient top gear, a compact construction and a wide overall range of gear ratios. The automatic transmission has a speed changer which provides five gear stages, namely two speeds on the speed decreasing side and two speeds on the speed increasing side with a direct-coupled gear therebetween. The speed changer includes a ring gear connected to an output shaft, a first carrier, a first sun gear, a second carrier connected to the first carrier, a stepped pinion gear supported by these two carriers, and a sun gear meshing with the pinion gear. The first carrier is connected to an input shaft by a clutch and the first sun gear is connected to the input shaft by a clutch. The first sun gear may be stopped by a first brake, a second brake stops the second sun gear and a third brake is provided to stop a third sun gear. Top gear is achieved by meshing of the pinion gear with the second sun gear and the ring gear. Top gear is thus achieved with the equivalent of only one planetary gear set of intermeshing elements and without loss of efficiency. Also, the arrangement of the three planetary gear sets of the transmission is such that one planetary gear set can be easily removed to make a 4-speed transmission derived from the 5-speed transmission of the invention.
