  • Patent number: 11371605
    Abstract: A control device for automatic transmission of the present invention includes a transmission mechanism and a park lock device. The park lock device has a rod member and a lock mechanism. The lock mechanism restricts movement of the rod member when being in a locked state. If a CPU reset (reset of a CPU constituting an ATCU) occurs, the control device maintains the locked state of the lock mechanism after a return from the CPU reset.

  • Publication number: 20100033009
    Abstract: A method and a device for tightening a hydraulic parking brake are disclosed. In the method, a tightening force is generated in a first step by creating a hydraulic pressure in a parking brake circuit. To this end, a pressure generating unit driven by an electric motor is used. In a subsequent step, at least one motor-related parameter which permits a conclusion about the hydraulic pressure prevailing in the parking brake circuit is detected. Subsequently, an activation of a tightening force assistance device takes place depending on the detected motor-related parameter and without the necessity of providing a pressure sensor.

  • Publication number: 20090227423
    Abstract: During service and repair work on an electric parking brake (1) of a motor vehicle, there is the problem that, in order to switch into a service mode in which the parking brake (15) can be completely opened, in order for example to be able to exchange a brake cable, a special diagnosis unit must generally be used. A diagnosis unit of this type is however not always available in workshops. It is therefore proposed to carry out the switch into the service mode of the electric parking brake (1) with at least one control element (2,2a) of the motor vehicle. Here, it is provided that, for safety reasons and in order to avoid an undesired switch into the service mode, the actuation of the at least one control element (2, 2a) must take place according to a predefined input procedure.

The braking to stop device is constructed such that it makes it possible to convert a rotational motion on the input side into the axial lifting motion of the braking body for the displacement thereof from a braking position or positioning the braking body in a braking position. The braking to stop device is also constructed in such a way that it transmits the rotational motion on the input side to the braking body.
