Abstract
A control system for a vehicle, in particular for a truck trailer, has a control device which switches off the control system upon the occurrence of a fault. The control system of the vehicle includes a bistable mechanical display which can be controlled via a coil arrangement into, in each case, one of its stable positions and then displays either a fault condition or no fault condition. Upon switching off the control device because of a fault which has occured, the display is controlled into the “fault” position, and it remains there even without a power supply. Consequently, a faulty system can be detected at any time even without a power supply switched on.
Claims19
A control system for a vehicle, comprising:
- a control device that switches off the control system upon detection of a fault condition in the control system;
- a mechanical display including an element which is capable of being set into a first stable position and a second stable position, the first position visibly indicating the fault condition when the fault condition is present, the second position visibly indicating a non-fault condition when the non-fault condition is present, the position of the element being reversible via a coil arrangement;
- and
- an evaluation circuit coupled to the control device, the evaluation circuit detecting the switch-off of the control system and setting the element to be in the first position indicating the fault condition in response to the switch-off detection,
- wherein the element is maintained in the first position after the switch-off of the control system.
A control system for a vehicle, comprising:
- a control device that switches off the control system upon detection of a fault condition in the control system;
- a mechanical display displaying one of a first stable state indicating the fault condition and a second stable state indicating a non-fault condition, the state of the mechanical display being reversible via a coil arrangement;
- and
- an evaluation circuit coupled to the control device, the evaluation circuit detecting the switch-off of the control system and controlling the mechanical display to display the first stabe state indicating the fault condition in response to the switch-off detection,
- wherein the mechanical display displays the first stable state when the fault condition is present and no power is received by the control system.
