    摘要: A vehicle speed control system comprises a section for calculating a command driving force-required to make a sensed vehicle speed equal to a preset command vehicle speed, a section for calculating a command engine output in accordance with the command driving force and the command vehicle speed, a section for calculating a command engine speed corresponding to the command engine output from a predetermined engine torque-versus-speed characteristic relationship in an engine constraint state of minimum throttle setting and fuel cutoff inhibition when the command driving. force is negative, and a section for calculating a command transmission ratio in accordance with the command engine speed. When the driving force command is negative, the control system put the engine in the constraint state and controls a continuously variable transmission in response to the command transmission ratio so as to prevent undesired vehicle speed hunting.

    摘要: An apparatus for controlling the positioning of a throttle valve situated to control the amount of air permitted to enter an internal combustion engine operable in a plurality of control modes. The apparatus includes a driver responsive to a drive signal indicating a target throttle valve position for moving the throttle valve to the target throttle valve position, a sensor sensitive to the movement of the throttle valve for producing a digital sensor signal indicative of a sensed throttle valve position, and a control unit for producing the drive signal to bring the sensed throttle valve position into coincidence with the target throttle valve position. The disturbances introduced onto the driver and the sensor are estimated based on the target and sensed throttle valve positions. The target throttle valve position is corrected based on the estimated disturbances.

    摘要: A variable valve timing mechanism (VVT) for adjusting the valve timing of an intake valve of an internal combustion engine. The mechanism is hydraulically driven by oil pressure. An oil control valve (OCV) is provided on a cylinder head of the engine for controlling oil flow from a pump. A drainage pan in the cylinder head receives oil drained from various mechanical components of the engine. A drain passage drains oil from the control valve to a drain well. The oil in the drainage pan is also led to the drainage well. A wall, or dam, is formed between the drainage pan and the drainage well for restricting the oil flow from the drainage pan to the drainage well. This prevents the drainage well from being flooded when the flow rate of oil into the drainage pan increases dramatically, which improves the performance of the VVT mechanism.

    摘要: A microcomputer with a non-volatile memory has a plurality of nonvolatile data memory elements arranged in a matrix and a means for reading data from the memory elements in accordance with an address signal which specifies a position in the matrix. A protecting data memory element for storing at least one-bit protection data is disposed in the matrix. Whether a programming (writing), erasing or reading operation with respect to the data memory elements is to be allowed or inhibited is determined in accordance with the contents of the protecting data memory element which are read out in response to the address signal.
