- the axle portion 4 includes a reduction gear, a differential device, and a drive axle. The power of the engine 1 is transmitted to the drive wheels 5 via the torque converter 2, the variator 20 and the axle portion 4.
- the variator 20 is a continuously variable transmission mechanism, and includes a primary pulley 21, a secondary pulley 22, and a belt 23.
- PRI primary pulley
- SEC secondary pulley
- the PRI pulley 21 includes a fixed pulley 21a, a movable pulley 21b, and a PRI chamber 21c. In the PRI pulley 21, the PRI pressure is supplied to the PRI chamber 21c.
- the variator 20 constitutes a belt-type continuously variable transmission mechanism that changes speed by changing the winding diameter of the belt 23 by changing the groove widths of the PRI pulley 21 and the SEC pulley 22 respectively.
- the vehicle further includes an oil pump 10, a hydraulic control circuit 11, and a controller 12.
- the rotation sensor 41 is a variator input side rotation sensor for detecting the rotation speed on the input side of the variator 20.
- the rotation sensor 42 is a variator output side rotation sensor for detecting the rotation speed on the output side of the variator 20.
- the rotation speed on the input side of the variator 20 is specifically the rotation speed of the input shaft of the variator 20.
- the rotational speed on the input side of the variator 20 may be, for example, the rotational speed at a position where the gear train is sandwiched between the variator 20 in the power transmission path described above. The same applies to the rotational speed on the output side of the variator 20.
- the transmission 100 is a continuously variable transmission, and includes the variator 20, the hydraulic control circuit 11 and the controller 12 that control the transmission ratio in this way, the rotation sensor 41, and the rotation sensor 42. .

- FIG. 2 is a diagram showing a first example of an abnormality detection area.
- FIG. 2 shows an abnormality detection area E11 and an abnormality detection area E12 for disconnection abnormality, and an abnormality detection area F11 and an abnormality detection area F12 for deviation abnormality.
- the disconnection abnormality is an example of an electrical abnormality.
- the deviation abnormality is an abnormality in which the output value deviates from the normal value, and is an example of a function abnormality.
- the abnormality detection area E12 is an area corresponding to the disconnection abnormality of the rotation sensor 42. For this reason, the abnormality detection region E12 is set as a region where the rotational speed Nsec ′ is zero regardless of the rotational speed Npri ′.
- a portion of the abnormality detection region E11 where the rotational speed Nsec ′ is higher than the predetermined value Nsec11 and the abnormality detection region F11 form an overlap region. For this reason, when the operating point is included in this overlap region, it cannot be specified whether the cause of the abnormality is a disconnection abnormality or a deviation abnormality. The same applies to the abnormality detection region E12 and the abnormality detection region F12.
- the abnormality detection area E21 is an area corresponding to the disconnection abnormality of the rotation sensor 41. For this reason, the abnormality detection area E21 is set as an area where the current rotation speed Npri ′ is zero regardless of the rotation speed Npri ′ before the occurrence of the abnormality.
- the controller 12 performs the following control.
- step S1 the controller 12 determines whether or not the output value of the rotation sensor 41 is included in the abnormality detection area of the function abnormality. Whether or not the rotational speed Npri ′ is included in the abnormality detection region for functional abnormality is a parameter that defines the abnormality detection region for functional abnormality, and is determined based on a parameter including at least the rotational speed Npri ′.
- Detecting electrical anomalies is performed on a regular basis separately from the processing of this flowchart.
- the detection of the electrical abnormality may be performed by a controller other than the controller 12.
- the controller 12 may start counting the set time when an electrical abnormality detection flag is received from the other controller. Thereby, it can be determined whether it is during an electrical abnormality detection period by determining whether it is counting the set time.
- the count of the set time may be performed by the other controller.
- the controller 12 determines whether or not it is during the electrical abnormality detection period by determining whether or not it has received a status flag indicating that the set time is being counted from the other controller. Can do.
- step S2 If an affirmative determination is made in step S2, the rotational speed Npri 'is included in the abnormality detection area for functional abnormality during the set time counting. In this case, the controller 12 performs provisional fail-safe control as shown in step S3.
- the gear ratio of the variator 20 is controlled using the rotation speed Npri ′ immediately before being included in the abnormality detection area of the function abnormality as the rotation speed information.
- the immediately preceding rotation speed Npri ′ is used as rotation speed information obtained from the rotation sensor 41 instead of the erroneous rotation speed Npri ′ detected based on the output of the failed rotation sensor 41.
- the reason why the immediately preceding rotation speed Npri ′ is used is that the rotation speed Npri, which is the actual rotation speed of the PRI pulley 21, does not vary greatly in a short time.
- step S6 the controller 12 performs fail-safe control after the abnormality is confirmed.
- the controller 12 controls the gear ratio of the variator 20 by using at least the vehicle speed Vsp as the fail-safe control after the abnormality is confirmed without using the rotational speed information.
- the gear ratio of the variator 20 is controlled by open loop control based on the vehicle speed Vsp. For this reason, not only the rotation speed Npri ′ but also the rotation speed Nsec ′ is not used as the rotation speed information.

- the controller 12 further functions as a gear ratio control unit that controls the gear ratio of the variator 20.
- the controller 12 as the gear ratio control unit performs the provisional fail-safe control by performing the process of step S3 through the positive determinations of step S1 and step S2.
- the controller 12 as a gear ratio control part performs fail safe control after abnormality determination by performing the process of step S6 through the affirmation determination of step S4 or step S5.
- the controller 12 has these functional units by functioning as these functional units.
- the control device of the transmission 100 may be grasped as being realized by the hydraulic control circuit 11 and the controller 12.
- the controller 12 includes a variator 20 and a rotation sensor 41 and is a control device for the transmission 100 provided in the vehicle.
- the electric abnormality detection state of the rotation sensor 41 continues for a set time, the electric abnormality of the rotation sensor 41 is determined. To do.
- the controller 12 determines the function abnormality of the rotation sensor 41 and prohibits the function abnormality from being determined during the set time counting.
- an error code is recorded for each cause of abnormality, and when two or more error codes are recorded, that is, at the time of multiple failure, the transmission 100 is forcibly set to a neutral state to disable vehicle travel. Fail-safe control may be performed during multiple failures.
- the cause of the abnormality may be recognized as both an electrical abnormality and a functional abnormality in the overlap region of the abnormality detection area of the electrical abnormality and the functional abnormality. Absent. For this reason, it is also possible to prevent the fail-safe control at the time of multiple failure due to misidentification of the cause of the abnormality.
- the controller 12 further controls the gear ratio of the variator 20 by using at least the rotation speed information based on the normal rotation speed Npri ′ and the vehicle speed Vsp. As described above, the controller 12 that controls the speed ratio of the variator 20 performs provisional fail-safe control when the rotational speed Npri ′ is included in the abnormality detection area of the function abnormality during the set time counting.
- the controller 12 configured as described above, even when the rotation speed Npri ′ enters the abnormality detection area of the function abnormality during the electrical abnormality detection period, the shift of the variator 20 by using the incorrect rotation speed Npri ′ is performed. A sudden change in the ratio can be prevented.
- controller 12 controls the speed ratio of the variator 20, after the electrical abnormality or functional abnormality is confirmed, the controller 12 performs fail-safe control after the abnormality is confirmed.
- controller 12 configured as described above, it is possible to control the gear ratio of the variator 20 based on accurate information even when an electrical abnormality or a functional abnormality occurs.
