Vehicles with ESP
Part 1 Of 2
Part 2 Of 2
Location
The steering angle sensor (N49) is secured on the jacket tube interlocking with the contact spiral (A45).
Task
The task of the steering angle sensor (N49) which works on an optical basis is to record the steering angle specified by the driver and transmit it to
the connected systems.
Design
Digital sensor with 9 light-emitting diodes (a) for photoelectric barrier measurement. The steering angle sensor consists of 2 microcomputers
which form a unit with a signal measuring ring. The 9 light-emitting diodes (a) are equi-spaced on the signal measuring ring. They are located in a
photoelectric barrier channel which 8 apertures (b) of different lengths pass through. The photoelectric barriers are located in the upper section of
the spring contact (A45) and only form the complete Functional unit of the optical steering angle sensor (N49) by assembling (clipping together)
