摘要： An automatic transmission control system equipped with a shift lever position sensor which includes a plurality of switches which output binary signals following a shifting motion of a gear shift lever. Patterns of combinations of the switch outputs are preselected so as to represent positions to which the gear shift lever is manually shiftable. The switches are broken down into two groups each of which produces a binary code carrying information about the position of the gear shift lever to monitor a failure in operation of the shift lever position sensor. The control system also works to perform a deemed D-position hydraulic transmission control to ensure the running of the vehicle even if the shift lever position sensor is failing.

摘要： In performing a down-shift based on a driver's intention of deceleration, an engine output increasing control is started at a time when a transfer torque capacity of the releasing clutch becomes small or zero and the actual oil pressure decreases to an initial oil pressure, not causing an acceleration feeling even upon the engine output increase. For estimating a time when which the real pressure of the releasing clutch decreases to a level of not higher than the initial pressure, the response of the real pressure relative to an oil pressure command value for the releasing clutch is approximated using a transfer characteristic of “first order lag+time delay.” An estimated real oil pressure obtained based on the transfer characteristic is compared with the initial pressure. It is determined a start timing of the engine output increasing control has been reached upon decrease of the estimated pressure to the initial pressure.

摘要： A vehicle has a body, a right-hand wheel, and a left-hand wheel. A first device rotatably connects the right-hand wheel to the body. A second device rotatably connects the left-hand wheel to the body. An elastically deformable stabilizer is connected between the first and second devices. A mechanism serves to positively deform the stabilizer. A sensor may detect an operating condition of the vehicle, such as a steering condition or speed of the vehicle. The stabilizer may be positively deformed in accordance with the detected operating condition of the vehicle.

摘要： A hydraulic pressure of each corresponding one of a plurality of friction elements of a gear shift mechanism of the automatic transmission is controlled to downshift the gear shift mechanism from a current gear stage to a next gear stage, at which an engine brake is operated, upon receiving a driver's demand for deceleration. An engine output of the engine is increased by increasing a throttle opening degree of the engine in at least two steps in an absence of a driver's operation on an accelerator of the vehicle at the time of the downshifting of the gear shift mechanism from the current gear stage to the next gear stage.

摘要： An automotive automatic transmission control apparatus is provided which works to increase the power of an engine in response to a request to down-shift the gear of an automatic transmission for developing the engine braking. The control apparatus includes a fail-safe circuit working to stop increasing the power of the engine when a defect in operation of a transmission hydraulic control circuit is detected after the hydraulic control circuit starts to control the hydraulic pressures to achieve the downshift of the automatic transmission. This eliminates or alleviates a problem, such as unwanted acceleration of the vehicle during the control of the downshift in the transmission.

摘要： A vehicle automatic transmission control controls fluid pressure changes applied to a frictional engagement element which is being changed from an engaged state to a disengaged state at a stage before input shaft rotational speed starts to increase from the beginning of a down-shift control. The control instruction value is set to gradually decrease the applied fluid pressure and to increase the ratio of such decrease with elapsed time. Specifically, a solenoid is used to control the fluid pressure applied to a clutch. The duty-cycle instruction for the solenoid is determined based on a quadratic function expressed as: duty cycle value=initial value-at.sup.2.

The control apparatus includes a hydraulic cylinder unit coupled between one end portion of the twistable stabilizer and one of the wheels and the cylinder unit has a cylinder body and a piston slidable therein to be expandable and contractable in accordance with movements of the piston. Also included in the apparatus is a hydraulic actuator comprising control valves and coupled to the cylinder unit to control a position of the piston, the position thereof corresponding to the twisting amount of the stabilizer and being detectable by a position sensor. A control unit determines a predetermined stable condition of the vehicle on the basis of a steering angle of a steering wheel, which is detectable by a steering sensor, and obtains a neutral position of the piston taken under the condition that the vehicle is in the predetermined stable condition. Further, the control unit determines a turning state of the vehicle on the basis of the steering angle and to determine a target piston position with respect to the neutral position in accordance with the degree of the vehicle turning state, then outputting a control signal to the actuator so that the piston assumes the target piston position.
