摘要:
A vehicle equipped with a motor-operated mechanism that contains a clutch. The pushing member of the clutch is energized against a friction plane by an energizing mechanism and transfers power from a driving power source when it touches the friction plane. The location of the pushing member can be retained even when power is shut off. This structure prevents promotion of deterioration of a diaphragm spring in a state in which the clutch remains disengaged when the key switch is turned off.After a signal from the key switch stops, the control apparatus stops the driving power source and the vehicle, engages the friction transfer mechanism, and then stops the system.

A metal oxide catalyst material which comprises one or more of transition metal elements having a 4d shell electron or a 5d shell electron as an electron bearing the electroconductivity thereof; and a catalyst for treating a combustion exhaust gas comprising the catalyst material. The contact of an exhaust gas with the metal oxide catalyst material allows harmful substances such as nitrogen oxides contained in the following exhaust gases to be decomposed or removed as a whole and simultaneously. The catalyst material and the catalyst can be suitably used for removing harmful materials such as nitrogen oxides, hydrocarbons, diesel particulates, carbon monoxide, carbon dioxide and dioxins, which are discharged from an automobile, a ship, an airplane, a glass melting furnace, a steel product heating furnace, a coke furnace, a cement firing furnace, a steel sintering furnace, a high temperature furnace such as a converter, an incinerator, a rocket engine, a thermal power station, a boiler, a plant for producing a catalyst or a chemical such as phosphoric acid, facilities for treating a metal or petroleum, a petroleum stove, a gas range or the like.

An object of the present invention is to provide a control unit for vehicle where increase in number of input/output and upgrading of function can easily be performed and, in addition to this, changing of a program in a control unit can easily be performed even when a single-chip micro-computer is used. In order to cope with an increase in input/output points and addition of function, a control unit is constructed such as to comprise interface software memory means storing an interface software program for connecting an application software program with an OS (operating system) in an internal ROM, a CPU (central processing unit) for performing computation of the application software program and the interface software program, a RAM (erasable memory) storing data such as the result of computation, an I/O unit for extending the control unit, and extending means for communicating memory data through a bus or a LAN. A single-chip micro-computer used in vehicle control can easily cope with increase in input/output points or addition of function, and an application software program can continuously be used only by rewriting an interface software program, and further re-manufacturing of a core unit is unnecessary. Therefore, development of a control unit including programs becomes easy.

A transmission control system can reduce degradation of engine characteristics upon shifting operation and can reduce a load on the side of a clutch and a transmission due to delay of response. The transmission control system includes an engine generating a driving force, a transmission having a plurality of gear positions for transmitting the driving force developed by the engine to driving wheels, a clutch for connecting said engine and said transmission, engine control means for controlling the engine, transmission control unit for switching gear positions of the transmission, and clutch control unit for controlling disengagement and engagement of the clutch. The transmission control system further includes an electric motor connected to a drive shaft of the engine and capable of performing regenerating operation, and motor control unit for controlling said electric motor for driving the electric motor for generating a driving force or for performing regenerating operation. The motor control unit transmits said driving force to the driving wheel upon shifting operation by the transmission and performs regenerating portion by an energy from the driving wheels.

A vehicle which includes a plurality of peripheral systems has a plurality of control units which transmit data to each other via a local area network, and which control the peripheral systems in response to sensor signals received from vehicle operating parameter sensors. A first control unit has a memory which stores a first interface software program which receives input signals from sensors and processes such signals for controlling at least one peripheral system of the vehicle, by means of an application software program and first and second interface software programs. A second control unit has a memory which stores an application software program for processing input signals for controlling at least one other peripheral system of the vehicle via a third interface software program. The second control unit receives input data from the first control unit via the local area network.

A power train controller and control method are provided for a passenger car driven by a combustion engine and an automatic gear changing transmission. Control sensors detect a current operating state of the passenger car. Three different modes of operation, including sports mode, economy mode, and comfortable mode are selected by the driver. Depending on the selected mode, the automobile transmission is controlled in different shifting patterns as a function of the sensed vehicle operating conditions.

A signal detector is located before an automatic transmission for detecting timing such that torque outputted from a torque converter of the automatic transmission at the moment of upshifting changes from clutch before shift to clutch after shift. A signal detector is located after the automatic transmission for detecting timing such that torque outputted from a torque converter of said automatic transmission at the moment of downshifting changes from clutch before shift to clutch after shift. An apparatus executes the driving shaft torque control in response to the changes in both torque signal detectors.
摘要:
In a multi-cylinder engine, amounts of fuel injection supplied to respective cylinders are individually corrected on the basis of a signal from A/F sensors in the number less than the number of cylinders of the engine, for example, one A/F sensor, so that the air/fuel ratios for respective cylinders are feedback-controlled at a substantially uniform predetermined air/fuel ratio. Therefore, it is possible to perform precise air/fuel ratio control so as to accurately maintain the air/fuel ratio of the engine at the stoichiometric air/fuel ratio, to reduce the concentrations of HC, CO, and NOx in exhaust gas.
