Abstract: A housing for electric componentry comprises a closed frame in which the electric componentry is received, a first electric connection element which is connected to the electric componentry and passes through a wall of the frame, a second electric connection element which is connected to the first electric connection element, and an electric connection cable which is connected to the second electric connection element. A fastening element fastens the electric connection cable to the frame of the housing in such manner that the cable lies parallel to a flat outer surface of the frame. At least a part of the fastening element is constructed integrally with the housing. In a preferred embodiment, the housing further comprises a cover attached by a hinge to the frame. Further, the fastening element comprises first and second parts which bear upon each other with the electric connection cable therebetween.

Abstract: An error detection and display system for an apparatus having first and second operating states comprises a testing device, a display unit (e.g., a warning light), and a switch-on control unit. The testing device runs primary error test cycles for detecting errors of a first kind which occur during the first operating state of the apparatus (e.g., a vehicle at standstill), and secondary error test cycles which occur and can be detected only in the second state of the apparatus (e.g., the vehicle moving above a predetermined minimum speed). The system also includes a non-volatile memory wherein all occurrences of errors of the second kind are stored. The switch-on control unit switches on the testing device and the warning light when the vehicle is first started. If no error of the first kind is detected by the testing device and no error of the second kind is stored in the error memory, the switch-on control unit switches off the warning light while the vehicle is still at a standstill.

Abstract: An anti-lock brake system for vehicles with an electronic system which regulates the braking pressure of a monitored wheel as a function of the wheel speed, so that locking is prevented. The system is designed so that each wheel has its own speed sensor, and both wheels of one axle are pressurized with pressure medium by means of a joint control valve controlled by the electronic system. This arrangement corresponds to that of a select-low regulation. To shorten the extended braking distance on roads with different traction on each side, which occurs with a select-low regulation, the control system is designed so that when a retard signal (-b) occurs, the electronic system does not switch as usual to "remove pressure", but, at least until the occurrence of a slip signal (.lambda.), the control valve is switched to the "maintain pressure" position.
