摘要： PURPOSE:To facilitate the adjusting operation of car height and the loading/ unloading operation of loads by automatically adjusting the car height via solenoid changeover valves from the next time, after the car height manually adjusted has been stored, in accordance with the deviation of the detected car height from the stored car height. CONSTITUTION:The car height is adjusted by changing over solenoid changeover valves 12, 12a by means of a manual operation switch 5 to communicate an air spring 13 with an air tank, not shown, or the atmosphere. In this case, the detected signal of a car height sensor 6 is stored in the memory 14 of an electronic control unit (car height correction means) 7 through a memory setting means 17. and the car height signal stored in the memory 14 is transmitted to the car height correction means 7 through a car height calling means 15. Then the car height signal from the memory 14 is compared with the detected signal from the car height sensor 6, and the signal for making the deviation zero is transmitted to the solenoid changeover valve 12, 12a through the car height correction means 7. Thus, from the next time, the car height can be automatically adjusted to a prescribed stored car height.

摘要： PURPOSE:To make it possible to always perform smooth shift operation of an electronic control type automatic transmission in which a clutch is controlled in accordance with a clutch position learning value but is controlled by a substi tuting value when the leaning value vanishes away, by compensating the substi tuting value in accordance with a measured value of the time of speed change manipulation of the transmission. CONSTITUTION:An electronic control device 6 stores, in its memory, a clutch learning value which is a stroke of a clutch 3 when the difference between the rotational speed of an engine and an input rotational speed of a transmission 2 reaches a predetermined value during the clutch is gradually engaged from its disengaged condition. During normal control, an clutch actuator 8 is con trolled in accordance with the learning value so as to engage and disengage the clutch 3. Meanwhile, when the clutch learning value vanishes away, if the clutch 3 is controlled in accordance with a back-up value (substituting value), upon on-shift manipulation of the transmission 2, the time of shift manipulation is measured, and when thus measured value exceeds a predetermined value, the back-up value is compensated in the clutch disengaging direction by a set value.

摘要： PURPOSE:To make emergency starting at the time of trouble in a vehicle smoothly performable, by setting the relationship between an accelerator pedal operating quantity and a fuel supply down to a nonlinear form. CONSTITUTION:When trouble occurs in an electronic controller 1 and a vehicle becomes undrivable, a power source is selected to an emergency controller 2 by a power selector switch 14, making it operate. In this state, if a driver puts a gear in first or backward by an emergency gear switch 15 and operates an accelerator pedal, the emergency controller 2 feeds fuel to an engine 3 corresponding to an accelerator pedal operating signal, while it drives a clutch 4 so far coming into a state of being disengaged in the on-direction. Here a signal out of the potentiometer installed in an emergency accelerator sensor 13b has a nonlinear characteristic to the accelerator pedal operating quantity. With this constitution, while this accelerator pedal operating quantity is in the initial stage, a fuel supply is small so that engine speed fails to go up, and in this low speed state, such control that makes the clutch 4 come on is carried out whereby it comes to smooth starting less in a shock.

摘要： PURPOSE:To correctly set the neutral position of a shift actuator and the shift position in each speed change stage by performing renewal by using the detection value of a stroke sensor in the operation of a shift actuator to a neutral state, as learned value. CONSTITUTION:The shift quantity of a shift actuator 1 in the operation to a neutral stage is detected by a stroke sensor 4, and the aimed shift value is renewed by using the detected shift value as the learned value, and the aimed shift value in the neutral stage is set. When the aimed shift value in each speed change stage is set, setting is performed by adding the offset value onto the aimed shift value in the neutral stage as standard. The time after the lapse of the prescribed time set in the shift operation is considered as the completion of the shift operation. Since the shift position is renewed and set by using the value detected by the stroke sensor 4 as the leaned value, the neutral position as standard can be correctly set without using the torublesome adjusting process.

摘要： PURPOSE:To prevent a gear from being disengaged at the time of controlling a speed change in an emergency by making a shift operation continue until a certain period of time elapses after a clutch is engaged at the time of controlling a gear engagement to a 1st or reverse stage. CONSTITUTION:In case a malfunction occurs in an electronic control device 1 during driving, a power source changeover switch 14 is switched to an emergency control device side. If an emergency gear switch 15 is operated to a 1st speed, a clutch is disengaged and a gear is shifted off. Then a solenoid valve Ve1 is turned on, a select actuator 17 is selected to the 1st speed - R position, and 0.5 second thereafter the solenoid valve Ve1 is turned off. Then a solenoid valve Ve3 is turned on to shift in the direction of the 1st speed and to read a signal from an emergency acceleration sensor 13b. Controlling a rotary angle of a motor 25 to a rotary angle corresponding to said signal, the solenoid valve Ve3 is turned off to finish a shift operation.

摘要： PURPOSE:To prevent shifting of a piston by providing the third solenoid valve for opening fluid pressure supply lines of the first and second solenoid valves to a tank, thereby to open fluid pressure supply lines to the tank. CONSTITUTION:When a solenoid valve 6 is on, and a solenoid valve 2 is ON, oil pressure is supplied to the left chamber 1c of a cylinder 1, so that a piston 16 is moved to the right to shift a shift lever 8 to the gear first speed side. The shifting is detected by a position switch 9, and a signal is sent to an electronic control device 10. When the solenoid valve 6 is ON, and the solenoid valve 3 is ON, the shift lever is reversely shifted to the gear backward side. Accordingly, it is possible to overcome the disadvantage caused by lag in timing when two solenoid valves 2, 3 are OFF.

摘要： PURPOSE:To obtain the same clutch feeling at all times regardless of the wear of a clutch by detecting the abrasion wear of the clutch-driven plate of an automatic clutch and by correcting the control valve of a clutch actuator in response to the depth of wear. CONSTITUTION:In an automatic clutch, by closing an electromagnetic feed valve 15 and opening an electromagnetic exhaust valve 16 to connect an oil chamber 10e of an actuator 10 to a tank 12, a clutch pressure plate 3 is moved left by the spring forces of a clutch spring 4 and a return spring 10d; thus the clutch is set on. At this time, the distance L1 from the stopper position of the actuator 10 at full stop to the half-clutch start position is obtained from the outputs of a clutch stroke sensor 20 and an input rotation sensor 21, which is compared with the expected value L. And, from the difference obtained, the depth of wear of the clutch-driven plate 2 is gained and the control is made to correct the control value of the actuator in response to the depth of wear.
