Abstract
A motor vehicle has rear wheels being steered with the aid of a drive and an adjusting piston. A circuit configuration for detecting a steering lock angle of the rear wheels includes a first potentiometer detecting a displacement of the adjusting piston. The first potentiometer has a setting contact and electric terminals. A second potentiometer has a setting contact being moved as a function of the wheel steering lock and it has electric terminals. Two resistors are each connected in series with a respective one of the potentiometers. An evaluation circuit in which the steering lock angle is determined, is connected to the electric terminals and the setting contacts.

In a motor vehicle having rear wheels being steered with the aid of a drive and an adjusting rod, a circuit configuration for detecting a steering lock angle of the rear wheels, comprising:
- a first potentiometer detecting a displacement of the adjusting rod, said first potentiometer having a setting contact and electric terminals;
- a second potentiometer having a setting contact being moved as a function of the steering lock angle and electric terminals;
- a first resistor connected in series with said first potentiometer and a second resistor connected in series with said second potentiometer;
- and
- an evaluation circuit in which the steering lock angle is determined, said electric terminals of each of said first and second potentiometers and said setting contact of each of said first and second potentiometers being connected to said evaluation circuit.
