- the failure of the front actuator 20 or the rear actuator 30 may be, for example, a failure in which the motors 21 do not drive, or the reduction mechanism 22 locks and stops driving.
- this determination is based on the torsion degree setting value (rotation angle setting value) of the front stabilizer bar 25 or the rear stabilizer bar 35 based on the drive signal of the ECU 50 and the actual rotation input from the rotation angle sensor 60. This is done based on the angle. That is, for example, if the ECU 50 When a drive signal is output to twist the stabilizer bar 25 by the set angle ⁇ , the actual twist rotation angle of the front stabilizer bar 25 detected by the rotation angle sensor 60 deviates from the set angle ⁇ by a predetermined angle or more.

- step S 105 the ECU 50 calculates a drive signal to be output to the rear actuator 30. That is, based on the rotation angle of the front actuator 20, the front stabilizer bar 25 outputs and calculates the roll moment amount for the vehicle 1. Then, a drive signal amount (for example, current value) to the rear actuator 30 for generating the rear stabilizer 35 with the same roll moment as that value is calculated. Then, the process proceeds to step S106.
- a drive signal amount for example, current value
- step S106 the ECU 50 outputs a drive signal to the rear actuator 30.
- This drive signal is a drive signal for twisting the rear stabilizer bar 35 in the S direction (reverse direction) shown in FIG. 6 with respect to the rear actuator 30. That is, the ECU 50 outputs a drive signal to the vehicle 1 so as to give a rightward roll moment (a roll moment in a direction against the leftward roll moment applied to the vehicle 1 by the front stabilizer bar 25).
- Figure 7 shows the state after the operation.

- the front stabilizer bar 25 and the rear stabilizer bar 35 of the vehicle 1 cancel each other out of the roll moment applied to the vehicle 1. Therefore, even if one of the front stabilizer bar 25 and the rear stabilizer bar 35 of the vehicle 1 is fixed in a twisted state, the vehicle 1 can be prevented from being inclined. As a result, the stability of the vehicle 1 can be ensured.
- step S107 the ECU 50 outputs a signal for issuing an alarm to the display device 70.
- the display device 70 is turned on, and the user can recognize the abnormality.
- the ECU 50 outputs to the rear actuator 30 a drive signal for twisting the rear stabilizer reservoir 35 so as to apply a leftward roll moment to the vehicle 1.

- the ECU 5 0 when the rear stabilizer bar 35 is fixed in a twisted state so as to give a rightward roll moment to the vehicle 1, the ECU 5 0 outputs a drive signal to the front actuator 20 to twist the vehicle 1 so as to apply a leftward roll moment to the vehicle 1.
- the ECU 50 applies a rightward roll moment to the vehicle 1 with respect to the front actuator 20. Outputs a drive signal that twists to give.
- the ECU 50 controls both the function of controlling the drive signal in the normal state (the function of the first control means) and the function of controlling the drive signal in the abnormal state (the function of the second control means).
- the configuration is provided, separate control means may be provided for each. In that case, in the flowchart of FIG. 4, the process may be divided between step S103 and step S104.
- the display device 70 is provided so that the user can recognize the abnormality. However, if it is not necessary, the display device 70 may not be provided. Further, the ECU 50 may have a configuration in which step S107 is not performed in the flowchart of FIG. Industrial applicability
- the present invention can be applied to a stabilizer control device used to stabilize rolling (rolling) during running of a vehicle.
- FIG. 1 A block diagram showing an electrical configuration of a stabilizer control device.
- FIG. 2 is a diagram showing a state in which a stabilizer control device is mounted on a vehicle.
- FIG. 3 is a diagram showing a configuration of a stabilizer actuator provided in the stabilizer control device.
- FIG. 4 is a flowchart showing processing by the control means of the stabilizer control device.
- FIG. 5 is a diagram showing a state in which a rightward roll moment is generated in a vehicle.
- FIG. 6 is a diagram showing a state in which an abnormality occurs in a vehicle, and a roll moment receiving an external force is generated in the vehicle.
- FIG. 7 is a diagram showing a state in which a rear actuator of the vehicle is operated from the state shown in FIG. 6
- Front stabilizer actuator (first driving means or second driving means)
- Front stabilizer bar (1st stabilizer bar or 2nd stabilizer bar) Rear stabilizer actuator (second driving means or first driving means) Rear stabilizer bar (second stabilizer bar or first stabilizer bar) Steering angle sensor (rolling detection means)
- ECU first control means and second control means
- Rotation angle sensor tilt degree detection means
