Description

technical field

[0001] The invention relates to an electronic control unit according to the preamble of claim 1 and to a braking system according to the preamble of claim 16 . Background technique

[0002] Frequently, modern vehicles have an electric parking brake. The electric parking brake can be actuated by the driver via an actuating switch which is connected to an electronic control unit which actuates the actuation of a common or two separate parking brakes for both wheels mechanism. What is to be expected in terms of safety is that the electric parking brake works reliably even in the event of a single error.

[0003] An electromechanical parking brake device for a motor vehicle is known from DE 19751431 A1, which comprises a brake operating device, an electronic control device for converting an input signal into a corresponding output signal, and two motor-operable parking brakes. The brake can be manipulated according to the output signal of the control device. ...
