If a tilt angle which is not tolerable (because it is greater than the reference angle, corresponds to an accident) is now determined by the inclination sensor, then the control device intervenes in a suitable manner in the drive of the platform.

  • a further advantage of the solution according to the invention over the prior art is that the control of the synchronization of the platform according to the invention takes place depending on the angle of inclination.
  • a large inclination angle of the platform means a greater risk of tilting than a smaller angle of inclination.
  • a pitch-dependent control is to be understood that at a greater angle of inclination, the countermeasures initiated by the control are greater or stronger than at a smaller pitch angle. For example, at a larger inclination angle, the inflow of hydraulic oil to the hydraulic cylinder, which is on the trailing side, is increased to a greater extent than at a smaller inclination angle.
  • the parking device according to the invention thus adapts its control to the respective current inclination of the platform and thereby more quickly and efficiently produces an inclination angle of the platform within the tolerance.
  • This control of the synchronization of the movement of the platform which is always precisely matched to the current requirements, therefore represents a significant improvement in terms of the longevity of the parking device as well as of the comfort when using the device. It is particularly advantageous in the solution according to the invention that in addition to the information about the current inclination angle of the platform of the parking device, as described in the previous paragraph, also the temporal change of this current inclination angle can be incorporated into the control of the synchronization.
  • this temporal change of the inclination angle as an input to the automatic control of the synchronization of the platform leads to an even faster and more efficient control. If, for example, a rapid change in the angle of inclination, in other words a large temporal change in the angle of inclination, is determined, the counteracting of the inclination of the platform is correspondingly regulated to a greater extent than would be the case with a small temporal change of the inclination angle. For example, in the case of a large temporal change of the inclination angle, the inflow of hydraulic oil to the hydraulic cylinder of the trailing side is increased in proportion to the amount of change in the inclination angle with time.
  • a rapid temporal change of the inclination angle is thus countered with a correspondingly fast-acting, efficient countermeasure. This ensures that the production of an angle of inclination within the tolerance range is achieved faster than would be possible with a control without taking into account the temporal change of the inclination angle. If, after a large time change of the inclination angle with a correspondingly initiated rapid countermeasure, a smaller time change of the inclination angle is again measured, the countermeasure, for example the inflow of hydraulic oil on one side of the platform, is accordingly slowed or reduced again. This significantly reduces the risk of overloading the angle of inclination of the platform in the opposite direction.
  • the use of the temporal change of the angle of inclination as input information to the control thus also serves to the number of control loops to restore a tilt angle of the platform, which is within the tolerance to reduce. According to the invention thus contributes to the described use of the time derivative of the inclination angle to a significant improvement in the control speed and control quality for a uniform movement of the platform of a parking device at.

It can now (and this is the preferred variant) the leading side be braked something, including, for example, provided in the hydraulic supply solenoid valves or valves are closed for a short time and so on the hydraulic pressure and flow Disconnect the hydraulic fluid.
