Provided is a control device that includes a plurality of communication units that receive data from measurement control devices; a control unit that calculates an operation signal for controlling a controlled device on the basis of the data from the communication units and that outputs the operation signal to the controlled device; a storage unit that stores the data; a first monitoring unit and a second monitoring unit that perform a calculation on the basis of the data to calculate a calculation value, that determine whether the calculation value satisfies a blocking condition, and that output a blocking signal when the calculation value satisfies the blocking condition; and a first blocking unit and a second blocking unit that block the operation signal to the controlled device upon receiving the blocking signal output from at least either one of the first monitoring unit and the second monitoring unit.

A data transmission apparatus (100) selects transmission object data to a remote control terminal (101) based on acquired point group data (20). At this time, an upper limit of a data quantity of the transmission object data in a predetermined region is determined.

This invention relates to a procedure for assessing a signal representing the manual actuating force acting on an adjusting tool for the electrical, pneumatic and/or hydraulic actuation of adjusting means which, at least in the operational state in which the adjusting tool interacts with the adjusting means, serve for the alignment of units and/or sensors of a vehicle. According to this invention, the adjusting tool's drive is blocked if the manual actuating force exceeds a threshold value and/or if a measuring signal representing the alignment of the unit and/or of the sensor is assessed as incorrect and not allowed and/or a signal indicating an error status is generated.
