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： If a driver wishes to start off an automotive vehicle in second or third gear when the vehicle is at rest on a road surface having a low coefficient of friction, as is the case when a road surface is covered with snow, the driver operates a winter mode selection switch while the transmission is in the speed range in which the vehicle ordinarily travels, i.e. the D range. After the vehicle has started off in the higher gear following use of the switch, the transmission switches over to the ordinary travel mode automatically as vehicle velocity rises. In a case where the engine is turned off and then restarted, the transmission switches over to the ordinary travel mode automatically. This eliminates any inconvenience that might be caused by forgetting to operate the switch prior to the restarting of the engine.

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： A fail-safe control device for an electronically controlled automatic transmission mounted on a vehicle is provided with a sensor for sensing the number of revolutions input to the transmission and a sensor for sensing the number of revolutions output from the transmission or from a car speed sensor. The actual gear ratio of the transmission is calculated in accordance with the number of revolutions input to the transmission and the number of revolutions output from the transmission or from the car speed sensor each obtained from said sensors. The time taken for changing the actual gear ratio at the time of shift initiation to the fixed gear ratio after the shift is measured. A predetermined shift time which has been stored is compared with the thus-measured time for the purpose of detecting a failure of the transmission. As a result of this, a driver can take a measure such as performing an emergency control or the like, and furthermore, the failure can be displayed by a failure alarm device so that the driver can arrange for repair.

摘要： In accordance with the invention, as shown, for example, in FIG. 1, when a second counter 14 attains a number of pulses n needed for period measurement, the time required for n pulses to enter is obtained from a second memory 16, which stores the time that prevailed n pulses ago, and a first memory 15, which stores the time prevailing when the present velocity signal enters. Vehicle velocity is calculated from the time obtained. A second timer 11 is reset whenever the velocity signal enters in order to check the pulse input time interval. When the value in the second timer 11 exceeds a predetermined value t, the second counter 14 is reset in order to remeasure the time required for the n pulses to enter. Thereafter, the contents of the first memory 15 are stored in the second memory 16 and the second timer 11 is also reset. Accordingly, when the value in the second timer 11 exceeds the predetermined value t, namely when the vehicle is traveling at a very low velocity, the system forgoes the calculation of vehicle velocity. As a result, shift signals are not outputted to the shift solenoids on the basis of a vehicle velocity different from the present vehicle velocity and, hence, an erroneous shift does not take place. The arrangement of the system is a simple one since only the clock signal of the microcomputer is utilized.

摘要： A fail-safe control device for an electronically controlled automatic transmission to be mounted on a vehicle, the fail-safe control device: detects the battery voltage; previously stores a standard battery voltage; makes a comparison between the thus-detected battery voltage and the above-described standard battery voltage; and switches to an emergency mode of turning off all of shift solenoids when the voltage deviates from the standard upon the comparison. As a result of this, generation of defects that shifting from high speed gear stage to a lower speed gear stage due to defective operation of the shift solenoid and disconnection or the like due to the overvoltage of the solenoid can be prevented. Furthermore, if a failure is detected, it can be notified to a drive.
