摘要： A solenoid driving circuit for an automatic transmission in which a potential difference compensating device, such as a Darlington-connected transistor circuit, switching transistor, and/or diode, is connected between a resistance element and a power ground, and a controlling device monitors voltage values at opposite sides of the resistor element so as to detect a current value flowing across a solenoid. The controlling device determines whether the detected value of the current flowing across the solenoid is abnormal, and the controlling device shuts off the current of a solenoid driving device when it is abnormal. The potential difference compensating device is provided with a switching device, and the controlling device turns off the switching device when the monitoring current value is abnormal. This circuit prevents an excessive current from flowing to the solenoid and an excessive discharge from the potential difference compensating device to the power ground owing to a short circuit with the supply line of a battery.

摘要： In a fail-safe control device for an electronically controlled automatic transmission to be mounted on a vehicle, a sensor for the number of revolution input to a T/M is newly provided for the electronically controlled automatic transmission, and an actual gear ratio of the T/M is calculated in accordance with the number of revolution input to the T/M and the number of revolution output from the T/M or the car speed. If the calculated actual gear ratio is coincided with the formal gear ratio, it is determined that the state is normal, while if they are not coincided with each other, it is determined that the T/M is in a failure state. As a result of this, failure detection of the T/M is performed. Therefore, in a case when the T/M is in a failure state, a driver can take a measure, for exmple, by performing an emergency control. Furthermore, the occurrence of the failure can be displayed by a detected failure displaying device so that the driver can take a measure such as a repair.

摘要： A sensed shift time and a standard value of shift time set for this shift are compared. If the result of the comparison is that the shift time does not fall within an allowable range of standard values, a signal outputted to a linear solenoid is varied in such a manner that the shift time will be held with the range of the standard values. Accordingly, actual shift time while a vehicle is traveling is constantly fed back and controlled so as to attain an optimum shift time. Therefore, even if a change in the shift time is brought about by a change in oil temperature in the transmission or by aging of friction elements or the like, the shift time can be corrected to an optimum value to improve shift sensation as well as the durability of the friction elements.

摘要： An electronically controlled automatic transmission installed on a vehicle. This transmission comprises a throttle body, a main throttle valve mounted in the throttle body, a subsidiary throttle valve connected in series with the main throttle valve, a traction control module connected with wheel rotation sensors, an engine control module receiving the output signals from the main and subsidiary throttle sensors, a transmission control module, and an automatic transmission. If the wheels skid, it is detected by the traction control module. The output signal from the traction control module causes the engine control module to reduce the engine torque. The transmission control module responds to the output signal from the traction control module and to the engine control module, and changes the line pressure. When the traction control module is operating, the transmission control module changes the line pressure by a predetermined value.

摘要： In a system for controlling a vehicle by exchanging signals between an electronic controller for controlling a vehicle transmission and another electronic controller for controlling a vehicle engine, the transmission controller incorporates a monitor circuit which receives, via an interface circuit of the engine controller, a signal output from the transmission controller through a communication circuit, and which is capable of detecting abnormalities of the interface circuit of the engine controller. If an abnormality of the interface circuit of the engine controller takes place such that the engine torque cannot be reduced although the transmission controller issues an instruction to reduce the engine torque, the transmission controller maintains the line pressure instead of reducing the same to cope with such a situation, thus effecting fail-safe control.

摘要： In engine torque control in a motor vehicle having an engine and a stepping type of transmission, input and output speeds of the transmission are constantly detected by sensors disposed in input and output portions of the transmission, thereby obtaining a gear ratio (measured value) of the transmission. If the ratio of the difference between this gear ratio and a predetermined gear ratio before the gearshift (theoretical value) to the latter gear ratio before the gearshift exceeds a predetermined value, the start of gearshift is decided. If the ratio of the difference between the gear ratio of the transmission (measured value) and a predetermined gear ratio after the gearshift (theoretical value) to the latter gear ratio after the gearshift becomes smaller than a predetermined value, the end of gearshift is decided. A set level by which the torque of the engine should be reduced during the period between the start and end of the gearshift is determined by reading reduction data previously set with respect to the throttle opening and the type of gearshift. The torque output from the engine is reduced on the basis of the reduction data by controlling the ignition timing retardation angle or the fuel injection rate.

摘要： An electronically controlled automatic transmission in which the transmission gear stage and engaging or disengaging operations of a lock-up clutch in a torque converter are determined on the basis of the number of transmission output revolutions and the throttle opening and in which a shifting solenoid and a lock-up solenoid incorporated in the transmission are controlled in. The transmission has a sensor for detecting an input rotational speed. The number of transmission input revolutions output from this sensor and the number of transmission output revolutions are compared with each other, thereby detecting malfunction of a transmission output speed sensor. If the transmission output speed sensor malfunctions, gearshift and lock-up control are performed on the basis of the number of transmission output revolutions calculated from the number of transmission input revolutions and the corresponding gear ratio. The transmission also has an malfunction alarm device for issuing an alarm indicating malfunction of the transmission output speed sensor in response to a signal output from an electronic control device. When both the transmission output speed sensor and the transmission input speed sensor operate normally, the number of revolutions output from the transmission output speed sensor and the number of transmission output revolutions calculated by the electronic control device from the number of transmission input revolutions and the gear ratio are compared, thereby detecting malfunction such as slip failure of a friction member in the transmission or shift failure.
