  • Patent number: 6676566
    Abstract: A control system for an automatic transmission of a vehicle is disclosed. The automatic transmission operates in a manual operating mode in which a shift position of the automatic transmission can be changed according to a shift instruction issued by a driver of the vehicle, or in an automatic operating mode in which the shift position is automatically selected. In the control system, a slow running intention of the driver is detected. A first shift position is set to a starting shift position at the time of starting the vehicle when the slow running intention of the driver is not detected in the manual operating mode. A second shift position which is lower in transmission gear ratio than the first shift position is set to the starting shift position when the slow running intention of the driver is detected in the manual operating mode.

  • Patent number: 6547695
    Abstract: A control system for a hydraulically-operated transmission for a vehicle is disclosed. The transmission is connected to a crankshaft of an internal combustion engine and having a plurality of friction engagement elements. A working oil temperature of the transmission, a cooling water temperature of the engine, and an operating condition of the transmission are detected. An estimated value of the working oil temperature is calculated on the basis of the detected cooling water temperature and the detected operating condition of the transmission. A weighting factor is calculated according to the detected working oil temperature. A weighted average value of the working oil temperature and the estimated working oil temperature is calculated as an actual working oil temperature by using the weighting factor. A hydraulic pressure of the working oil is controlled according to the actual working oil temperature.

  • Patent number: 6059689
    Abstract: A system for controlling an automatic transmission mounted on a vehicle, including an automatic mode in which a gear is retrieved from predetermined gearshift characteristics by the detected vehicle speed and the engine load and a manual mode in which a gear is designated by a device manually operated by a vehicle driver. In the system, a temperature in an exhaust pipe of the vehicle is estimated based on the detecting operating conditions and the gear designated in the manual mode is corrected to upshift by one gear, if the estimated exhaust pipe temperature is found to exceed a predetermined temperature, thereby improving avoidance of the occurrence of excessive thermal load of components in the vicinity of the exhaust pipe, and that, by not conducting forced upshift until such time, fully exploits the features of the manual mode and, by this, makes the product more appealing to customers.

  • Patent number: 6031508
    Abstract: An antenna adjuster includes a clamp unit 10 including an upper and a lower clamp disposed one above another in the height direction of a pole 2, the upper and lower clamps including paired clamp members 11 and 14, and 12 and 13, respectively. The paired clamp members face each other via the pole and are secured to the pole so as to be capable of position adjustment in the height and peripheral directions of the pole 2. An antenna mounting member 20 is mounted on the upper clamp member 11 for rotation about an elevation angle rotation axis member 23 and secured to the antenna 1. An azimuth angle adjusting member 30 is capable of being displaced through an elongate hole 32 formed in the upper clamp member 11 and a threaded hole 33 formed in the lower clamp member 13. An elevation angle adjusting member 40 is capable of being screwed through an engagement hole 42 formed in the antenna mounting member 20 and a nut portion 43 of the upper clamp 11 to push and pull the antenna mounting member 20.

  • Patent number: 5967941
    Abstract: A system for controlling an automatic transmission mounted on a vehicle, including a gear system and hydraulic clutches which hold a member of the gear system stationary to produce gear reduction or reverse to transmit engine output, and a linear solenoid valve provided in the oil line which generates an oil pressure to be supplied to hydraulic clutches in response to a current supplied thereto. In the system, the current supply is initiated when the ignition switch is turned to the ON position where the engine is not started, producing a noise due to the solenoid valve operation. In order to avoid this, the current is limited to a predetermined value when the engine is not started and the vehicle is stopped. Moreover, since the predetermined value is slightly above the current at which the clutch pressure begins to rise, the automatic transmission can start its operation quickly when the engine is started.

  • Patent number: 5531654
    Abstract: A control system of a vehicle automatic transmission in which an engine load and a vehicle speed are detected and used to determine a vehicle acceleration in accordance with the preestablished characteristics. An actual vehicle acceleration is at the same time calculated in response to the detected vehicle speed. The difference therebetween is then calculated and the calculated value is added to a difference calculated earlier to obtain an average therebetween. Five gear shifting scheduling maps, for example one for moderate hill climbing, one for level-road running, one for steep hill descent, are preestablished and in response to the average obtained, one of the maps is selected. A gear shifting is controlled based on the selected map. A driver's intention to decelerate is estimated and is compared with a reference value which increases with increasing said average indicative of the grade of hill that the vehicle is descending.
