摘要： PROBLEM TO BE SOLVED: To detect a trouble such as fixing of a friction engagement element of a transmission mechanism without performing the detection of rotation of a rotation member in the transmission mechanism. SOLUTION: A control unit 16 is provided with a processing function to determine a trouble of an automatic transmission in the case where the automatic transmission is not in a neutral condition in spite of a range selection condition detected by an inhibitor switch 15 to estimate that it is in the neutral condition because an engine speed or engine torque is not within a normal range of the neutral condition.

摘要： PROBLEM TO BE SOLVED: To employ an electric apparatus that has a low-cost structure and requires no measures against noises in an automatic transmission. SOLUTION: An automatic transmission holds a control valve, which is hollowed partly in the outer surface of its valve body 10 and is mounted in the hollow with an automatic transmission control unit(ATCU) 12 held separated from the inner surface of the valve body 10. The ATCU 12 is covered at its outer side in a first filler 14. The first filler 14, which has lower thermal conductivity and higher oil resistance, is further covered at its outer side in a second filler 16 with a predetermined clearance (a passage 22) held therebetween. The automatic transmission fluid having just flowed out of an oil cooler flows into the passage 22 from an inlet connection 22a and out from an outlet connection 22b.

摘要： PROBLEM TO BE SOLVED: To make the failure of an automatic transmission recognizable on the control device side. SOLUTION: A control device for an automatic transmission has a selected position detecting means 11 for detecting a selected position as a selected position selected by the intention of a driver, a shift pattern control means 12 for controlling a shift pattern of the automatic transmission according to the selected position detected by the selected position detecting means 11, 21 present position detecting means 13 for detecting a present selected position, a position coincidence judging means 14 for judging whether or not the selected position based on the driver's intention detected by the selected position detecting means coincides with the selected position detected by the present position detecting means 13, and a failure judging means 15 for judging the automatic transmission to be out of order when the position coincidence judging means 14 judges discordance of both selected positions.

摘要： PROBLEM TO BE SOLVED: To perform decision of the occurrence of a disconnection trouble to a signal system for a shift signal by a method wherein a manual operation indication switch comprises a normal close type switch having a contact brought into an OFF-state during operation. SOLUTION: Since a mode change over switch 3 for a manual mode is connected in series to a switch 4 being a normal close type and a minus switch 5 (a manual operation indicating switch), when a disconnection trouble occurs to either the signal line of a plus switch 4 or that of the minus switch 5, even when a device is brought into a state to be not in a D-range, when the mode change-over switch 3 is operated, either of the signal lines is brought into an OFF-state without fail, and since, when it is not in the D-range, operation of the switch 4 and the minus switch 5 is impracticable, this state is not normal, whereby it is decidable that a disconnection trouble reliably occurs.

摘要： PURPOSE: To simplify cryptographic operation while preventing easily generating erroneous operation. CONSTITUTION: In a control device for a vehicle having a control means (b) started by closing an ignition key switch (a) and having an operating switch (c) connected to this control means (b) so as to perform a prescribed process by the control means (b) in accordance with a signal obtained by prescribed cipher operation, as the operating switch (c), a momentary switch structure, turned on when performed pressing operation and turned off when released the pressing operation, is provided. The control means (b) is constituted so as to perform the prescribed process by deciding the cipher operation performed when input an on-signal from the operating switch (c) in the point of time started.

摘要： PURPOSE:To dissolve the false fault judgment of a communication line occurring by information being transmitted to a control unit in preparation by providing a control unit monitoring means and a communication permission means for permitting the communication between these when it detects that the control unit is capable of communication. CONSTITUTION:Each control unit 10 and 12 outputs a communication preparatory signal when the respective preparations of communication are not ready, and stops the output of the respective preparatory signal when the respective preparations are completed. Each communication preparatory signal is transmitted to a communication controller 18 by control signal lines 20 and 22, respectively. A communication controller 18 judges that the exchange of information is impossible between each control unit 10 and 12 in case that both sides or one side is inputted among each communication preparatory signal, and judges that the exchange of information has become possible when both ceases to be inputted among each communication preparatory signal, and transmits a communication permission signal to each control unit 10 and 12 by control signal lines 24 and 26.
