摘要： An apparatus including a slip control device for controlling an amount of slip of a lock-up clutch disposed between pump and turbine impellers in a power transmission system of a motor vehicle, a slip-parameter monitoring device for detecting the actual slip speed of the lock-up clutch or a control error between actual and target slip speeds of the lock-up clutch, a summing device for obtaining a sum of values of the actual slip speed or control error detected by the slip-parameter monitoring device for a predetermined period of time, and a defect detecting device for determining the presence or absence of a defect in slip control of the lock-up clutch by the slip control device, on the basis of the sum as compared with a predetermined reference. The slip-parameter monitoring device and summing device may be respectively replaced by a speed-parameter monitoring device for detecting a speed-related parameter which varies due to hunting in slip control of the lock-up clutch by the slip control device, and a smoothing device for smoothing the speed-related parameter. In this case, the hunting detecting device determines the presence or absence of the hunting defect on the basis of a difference of the speed-related parameter from its smoothed value.

摘要： In response to a signal indicating the present throttle valve opening degree detected by a throttle valve sensor and a signal indicating the present vehicle speed detected by a vehicle speed sensor, a lock-up controller determines whether a lock-up clutch should be brought into the operatively connected state or it should be released from the operatively connected state, and on completion of the foregoing determination, the controller outputs a certain signal to a solenoid valve. In the case that the lock-up clutch has been released, this state is maintained. On the contrary, in the case that the lock-up clutch has been in the operatively connected state, the controller determines whether maintains this state or selects a lock-up clutch releasing pattern depending on the present throttle valve opening degree. Specifically, the controller selects a pattern in such a manner that the operative connecting force of the lock-up clutch is quickly reduced at the time of coasting of a vehicle, it is slowly reduced at the time of an intermediate throttle valve opening degree, and it is appreciably slowly reduced at the time of a large throttle valve opening degree. With such control, a driver does not unpleasantly feel a stifling shock at the time of coasting, and moreover, acceleration behavior of the vehicle is enhanced at the time of a large throttle valve opening degree.
摘要翻译：响应于指示由节气门传感器检测到的当前节气门开度的信号和指示由车速传感器检测到的当前车速的信号，锁定控制器确定锁定离合器是否应进入操作连接状态，或者应该从操作连接状态释放，并且在上述确定完成时，控制器向电磁阀输出特定信号。在锁止离合器被释放的情况下，保持该状态。相反，在锁止离合器已经处于操作连接状态的情况下，控制器确定是否保持该状态，或者根据当前的节气门开度选择锁止离合器释放模式。具体地，控制器选择图案，使得在车辆滑行时快速减小锁止离合器的操作连接力，在中间节气门开度时缓慢减小，在节流阀开度较大的时刻，显着缓慢地减小。通过这样的控制，驾驶员在滑行时不会令人不愉快的感觉到窒息的冲击，此外，在大的节气门开度时车辆的加速行为增强。

摘要： An adaptive control of a lock-up clutch is disclosed. An initial value of an operating signal on which an electric actuator for the lock-up clutch operates is modified based on a deviation of a lag or delay from a target timer interval such that the initial value is increased when the lag is longer than the target time interval, while it is decreased when the lag is shorter than the target time interval.

摘要： A vehicle is provided with an engine and an automatic transmission having a lockup mechanism which engages and disengages to directly connect and disconnect input and output shafts of a torque converter of the automatic transmission to and from each other. A control system for such a vehicle has a deceleration detecting circuit which detects that the engine is decelerating based on the engine speed and a throttle opening, and a lockup mechanism control circuit which causes the lockup mechanism to engage when the engine is decelerating and permits the same to disengage when the deceleration of the engine finishes. The control system inhibits the lockup mechanism control circuit from causing the lockup mechanism to disengage in a period in which the engine speed can temporarily fall because of the automatic transmission's shifting into neutral in the process of a downshift.

摘要： Disclosed is a shift control for an automatic transmission adapted to shift speed ranges by coupling or decoupling of the friction coupling elements mounted on the transmission mechanism.The coupling force of the friction coupling elements is subjected to feed-forward control during a preset period after a signal of instruction for shifting was given. A control value for the feed-forward control is determined in accordance with control value characteristics which vary from a given initial value at a constant change rate.After the preset period, coupling force of the friction coupling element is feed-back controlled by of actual revolutions of an input shaft of the transmission mechanism. A final control value for the feed-back control is determined by determining a target change rate in the feed-back control by an amount of change in revolutions number of the input shaft of the transmission mechanism estimated by shifting and a set time for the feed-back control. With the target change rate, a target number of revolutions for each of plural control cycles obtainable by dividing the set time into portions. For each of the control cycles, the final control value is determined by comparing the actual number of revolutions of the input shaft and the target number of revolutions.

摘要： The torque capacity of a torque converter clutch is controlled with a two-state directional valve and a single solenoid operated pressure control valve. In operation, the directional valve is spring biased to a release state in which converter feed pressure is directed to a passage between the clutch plate and the converter input shell to release the clutch and feed the converter. The return fluid from the opposite (apply side) of the clutch is routed through the directional valve to a low pressure fluid cooler. A control pressure generated by the solenoid operated valve develops a hydraulic bias which opposes the spring bias. When the hydraulic bias is sufficiently great, the directional valve shifts to a control state in which the solenoid operated valve controls the pressure supplied to either the apply or release side of the clutch to control its torque capacity.

摘要： An electronic control system for operating a torque converter clutch during a transmission gearshift includes a vehicle speed sensor and engine speed sensor, a hydrodynamic torque converter located between the engine and the transmission, a solenoid-operated hydraulic valve, which engages and disengages the torque converter clutch in accordance with the energized and deenergized state of the solenoid in accordance with the logic of the control system. The converter clutch is locked while operating in the original gear ratio, then unlocks during the gearshift, and relocks after the upshift is completed. The speed ratio of the torque converter is rapidly determined in terms of the number of clock ticks occurring between pulses whose frequency is proportional to engine speed. The current speed ratio is determined during interrupts occurring at short intervals during a background pass.

摘要： A controlled system for the clutch in a torque converter of an automatic transmission wherein the clutch is normally engaged in a predetermined range of vehicle and engine operating conditions for efficient operation. An atmospheric pressure sensor is used in the control system to disengage the clutch in that predetermined range at higher altitudes to allow the torque converter to function to increase the torque being transmitted thereby compensating for the reduced engine performance at higher altitudes.
