Abstract: A vehicle control apparatus includes a first control section that shifts a vehicle from a normal running state to a coasting state by disengaging the clutch device of the vehicle when a predetermined execution condition is satisfied, a second control section that releases the coasting state when a brake operation or an accelerator operation is performed by a vehicle driver while the vehicle is in the coasting state, and an operation amount determination section that determines whether or not an operation amount of a brake operation or an accelerator operation performed while the vehicle is in the coasting state exceeds a release threshold. The second control section releases the coasting state if the operation amount is determined to exceed the release threshold, and does not release the coasting state if the operation amount is determined not to exceed the release threshold.

Abstract: A hydraulic coupling for use in a vehicle drivetrain to couple a pair of rotary members and includes a coupling mechanism supported in a casing and that is operable to couple the pair of rotary members together. A piston is responsive to pressurized fluid generated by a pump to move between first and second positions, thereby engaging the coupling mechanism. The pump has an outlet located in a direction away from the piston. An internal passage provides fluid communication between the outlet of the pump and an expandable chamber formed adjacent the piston. A control valve controls the flow of pressurized fluid from the pump between the sump and the expandable chamber.

Abstract: Improvements in one way clutches include a first embodiment directed to a one way clutch having two sets of helical teeth arranged about the axis of rotation of a drive and driven member that translate axially into and out of engagement. The one way clutch is biased into engagement by a wave washer or similar device. As the speed of rotation of the clutch increases, hydraulic fluid which is directed axially against the drive member by a dam urges the drive member away from the driven member and opens the clutch. In a second embodiment, a pair of one way clutches having oppositely arranged sets of helical teeth selectively provide one way or overrunning operation in both directions. In this embodiment, each of the drive members may be selectively engaged with the driven member by a hydraulic piston. Respective return springs bias the pistons and drive members toward disengaged positions.

Abstract: Clutch control values are determined via a method in a vehicle during a power-on upshift. Pressure to an offgoing clutch is decreased to a calibrated holding pressure after onset of the upshift. Proportional-integral-derivative (PID) logic of a controller is used to introduce a calibrated error into a pressure command to the offgoing clutch during fill of the oncoming clutch. This causes a calibrated slip to occur across the offgoing clutch, and a resultant threshold amount of flare to occur in turbine speed. The slip and flare are held using the PID logic. The pressure/torque relationship of the offgoing clutch is recorded. A fill level of the oncoming clutch is determined using a trajectory of an integrator term of the PID logic. A control value of the oncoming or the offgoing clutch is adjusted using at least one of the fill level, the recorded clutch pressure, and the recorded clutch torque.

Abstract: An apparatus and method are disclosed for controlling fluid flow in a motor vehicle transmission. At least one friction engagement device is fluidly coupled to a first pump, and a lubrication and cooling sub-system is normally fluidly coupled to a second pump. Illustratively, when a flow rate of the fluid in the first fluid passageway is less than a threshold fluid flow rate, a temperature of the fluid is greater than a temperature threshold and a fluid flow demand is greater than a fluid flow demand threshold, fluid flow from the second pump to the lubrication and cooling sub-system is blocked and fluid supplied by the second pump is instead directed to the at least one friction engagement device such that fluid is supplied by both the first and second pumps only to the at least one friction engagement device.

Abstract: The input rotation speed of an automatic transmission is fixed, and an output shaft is fixed. Oil pressure supplied to a measurement subject engagement element is then increased, and a determination is made as to whether or not rotary variation in a turbine rotation speed is equal to or greater than a set value. When the rotary variation reaches or exceeds the set value, an oil pressure controlled variable at this time is measured and stored. Then, on the basis of the measurement data, a correction amount relating to the unique characteristic variation of the automatic transmission incorporated into a vehicle body is determined and written to a TCU.

Abstract: A method of preventing a wheel loader from slipping, aiming at reducing the amount of slip of the loader during excavating operation using it, and preventing the decline in operational efficiency due to the slip. The method of preventing a wheel loader from slipping comprises the steps of detecting the occurrence of slip in accordance with the difference in the number of revolutions between a pair of left and right drive wheels and the change thereof, and controlling the clutch pressure so that the clutch is put in half-clutch condition upon detection of the occurrence of slip.

Abstract: An automatically coupling fan for the cooling system of automobiles, comprising a thermostat, in the form of a gas-tight container with a solid and a flexible wall, containing a liquid whose steam temperature within a predetermined temperature range couples the fan to the drive shaft of the motor by means of a friction clutch, characterized in that the thermostat has the form of a metal bellows which turns along with the water pump shaft. The bellows dimensions are such that the water ring generated during rotation of the thermostat by to the centrifugal forces exerted on the thermostat filler largely remains outside of the effective bellows cross-section (a.sub.w) and the fan is coupled in a predetermined temperature range almost exclusively by the filler steam pressure arising in the thermostat, or the filler quantity of the liquid medium in the thermostat is such that the water ring generated by the centrifugal forces working on the filler with the rotation of the thermostat in conjunction with the water pump shaft largely remains outside of the effective cross-section (a.sub.w) of the metal bellows and the fan is coupled in a predetermined temperature range almost exclusively by the steam pressure arising in the thermostat.
