摘要:
A vehicle drive control apparatus includes an engine that generates power through combustion of fuel, an automatic transmission that transmits a reverse input from a driving wheel to the engine and automatically performs a gear shifting among a plurality of forward gear stages each having a different gear ratio, a fluid power transmission device interposed between the automatic transmission and the engine for transmitting power through fluid, the fluid power transmission device having a lock-up clutch, and a controller. The controller executes a fuel cut control for stopping supply of the fuel to the engine upon establishment of a fuel cut condition including that a vehicle is in a coasting state where a throttle valve of the engine is fully closed, and an engine speed is equal to or higher than a predetermined value, executes a control for engaging the lock-up clutch upon establishment of a lock-up clutch engagement condition including that the vehicle is in the coasting state, and executes a control of the automatic transmission for downshifting at a coast down vehicle speed that changes in accordance with a state of the lock-up clutch under the control for engaging the lock-up clutch.

The formation mechanisms of devastating Hurricanes and Typhoons in the Northern Equator were analyzed.These Hurricanes and Typhoons have taken lives, property and devastation to the environment.We created a solution to save lives and the environmental effects. Hurricanes and Typhoons were found to form by the following two mechanisms: Mechanism (I): “High Sea-Surface Temperatures” along the Equator zone. Mechanism (II): “Anti-Clock-Wise Strong Westward Winds” along the Equator zone. We can prevent Mechanism (I). Various experiments were performed to prevent Mechanism (I). Results: spraying sea-water above the forming zone for about 20 min. reduces the Sea-surface temperature to 15.0° and prevents formations of Hurricanes and Typhoons. Also, as the best way to carry-out this process, is to find the high temperature zones by helicopters or drones equipped with Infrared-thermometers and guide Fireboat-fleets to the location even before the formations of Hurricanes and Typhoons.
摘要:
A shift device, which sends a command signal to an electric actuator for shifting a plurality of gear ranges of a transmission of a vehicle by the electric actuator. The gear ranges include a plurality of drive ranges and a parking range. A shift lever is arranged to move between a neutral position and a plurality of manipulation positions located about the neutral position. A restoration mechanism restores the shift lever to the neutral position. A first sensor electrically detects a manipulation performed to select one of the drive ranges. A second sensor electrically detects a manipulation performed to select the parking range. The first sensor detects toward which of the manipulation positions the shift lever is manipulated.

An automatic engine stop/restart-type vehicle and control method determine whether a vehicle is in a non-running range. The vehicle comprises: an engine; a transmission, an oil pump and a controller. The transmission has a coupling element that transmits an output torque of the engine. The oil pump supplies a hydraulic pressure to the transmission. The controller controls an output from the engine; controls the hydraulic pressure supplied to the transmission; and determines whether the engine is in an automatic stop state when a manually set mode of the transmission is shifted from a non-running range to a running range. A hydraulic pressure compensation procedure is performed to conform friction coupling characteristics of the coupling element and input characteristics of the transmission with each other if the controller determines that the engine is in the automatic stop state.
摘要:
A method for controlling gear shifting of a transmission in a vehicle. The transmission is supplied with electric power from a battery or an alternator and drives an actuator to shift gear ranges of the transmission. The transmission has an output shaft that becomes difficult to rotate if a predetermined range is selected when the engine stops running. The method includes determining whether a gear range differing from the predetermined range is selected when the vehicle stops traveling, and forcibly shifts the gear range to the predetermined range when a gear range differing from the predetermined range is selected by driving the actuator with electric power supplied from the alternator.
