Abstract

A monitoring device for monitoring systems of a vehicle, at least some systems of which having self-monitoring routines for self-monitoring and/or some systems of which having external monitoring routines for performing external monitoring of other systems which are not provided for the functions of their own systems or for self-monitoring.

Claims

1. A monitoring device for monitoring systems of a vehicle, in which there are at least one of some systems having self-monitoring routines for self-monitoring and some systems having external monitoring routines for performing external monitoring of other systems which are not provided for the functions of their own systems or for self-monitoring, comprising:

an activating arrangement to activate, when a malfunction or a fault is detected in at least one function assigned to a first system of the systems (ECPB), by self-monitoring routines of this first system (ECPB), a second system (EBS) by the one first system (ECPB) having the fault or the malfunction or by external monitoring routines of a third system monitoring this one first system (ECPB), wherein the activating arrangement is adapted to at least one of detect and localize the fault or the malfunction in the at least one function of the first system (ECPB) by at least one of actuators and sensors assigned to the second system (EBS), and activate an emergency operating program of the second system (EBS) as a replacement for the disrupted functioning of the first system.

3. The monitoring device of claim 1, wherein at least one of the self-monitoring routines and the external monitoring routines detect a fault or a malfunction of the at least one function of the first system (ECPB) by at least one of the type of the signals modulated by the first system (ECPB) and by the failure of signals modulated by the first system (ECPB) to occur.

4. The monitoring device of claim 1, wherein the first system is an electric parking brake device (ECPB), and wherein the second system is an electric service brake device (EBS) of a towing vehicle of a towing vehicle/trailer combination.

2. A monitoring device for monitoring systems of a vehicle, at least some systems of which have self-monitoring routines for self-monitoring and some systems of which have external monitoring routines for performing external monitoring of other systems which are not provided for functions of their own systems or for self-monitoring, comprising:

an activating arrangement to activate, when a malfunction or a fault is detected in at least one function which is assigned to a first of the systems (ECPB), by external monitoring routines of a second system (EBS), an emergency operating program of the second system (EBS) as a replacement for the disrupted function of the first system (ECPB).

8. The monitoring device of claim 2, wherein at least one of the self-monitoring routines and the external monitoring routines detect a fault or a malfunction of the at least one function of the first system (ECPB) by at least one of the type of the signals modulated by the first system (ECPB) and by the failure of signals modulated by the first system (ECPB) to occur.

9. The monitoring device of claim 2, wherein the first system is an electric parking brake device (ECPB), and wherein the second system is an electric service brake device (EBS) of a towing vehicle of a towing vehicle/trailer combination.

5. A monitoring device for monitoring systems of a vehicle, in which there are at least one of some systems having self-monitoring routines for self-monitoring and some systems having external monitoring routines for performing external monitoring of other systems which are not provided for the functions of their own systems or for self-monitoring, comprising:

an activating arrangement to activate, when a malfunction or a fault is detected in at least one function assigned to a first system of the systems (ECPB), by self-monitoring routines of this first system (ECPB), a second system (EBS) by the one first system (ECPB) having the fault or the malfunction or by external monitoring routines of a third system monitoring this one first system (ECPB);

wherein the activating arrangement at least one of perform at least one of the following;

(i) at least one of detects and localizes the fault or the malfunction in the at least one function of the first system (ECPB) by at least one of actuators and sensors assigned to the second system (EBS), and (ii) activate an emergency operating program of the second system (EBS) as a replacement for the disrupted functioning of the first system,

wherein at least one of the self-monitoring routines and the external monitoring routines detect a fault or a malfunction of the at least one function of the first system (ECPB) by at least one of the type of the signals modulated by the first system (ECPB) and by the failure of signals modulated by the first system (ECPB) to occur, and

wherein the sensors, which are assigned to the electric service brake device (EBS), contain at least one pressure sensor of a trailer control module (TCM,

     9), and wherein the actuators, which are assigned to the electric service brake device (EBS), contain solenoid valves of the trailer control module (TCM 9) for regulating pressure.

7. The monitoring device of claim 5, wherein the sensors which detect a fault or a malfunction in the electric parking brake device (ECPB) within the scope of self-monitoring, contain at least one pressure sensor of a parking brake module (PBM) and solenoid valves of the parking brake module (PBM) for regulating pressure.

6. A monitoring device for monitoring systems of a vehicle, in which there are at least one of some systems having self-monitoring routines for self-monitoring and some systems having external monitoring routines for performing external monitoring of other systems which are not provided for the functions of their own systems or for self-monitoring, comprising:

an activating arrangement to activate, when a malfunction or a fault is detected in at least one function assigned to a first system of the systems (ECPB), by self-monitoring routines of this first system (ECPB), a second system (EBS) by the one first system (ECPB) having the fault or the malfunction or by external monitoring routines of a third system monitoring this one first system (ECPB);

wherein the activating arrangement at least one of perform at least one of the following;

(i) at least one of detects and localizes the fault or the malfunction in the at least one function of the first system (ECPB) by at least one of actuators and sensors assigned to the second system (EBS), and (ii) activate an emergency operating program of the second system (EBS) as a replacement for the disrupted functioning of the first system,

wherein the first system is an electric parking brake device (ECPB), and wherein the second system is an electric service brake device (EBS) of a towing vehicle of a towing vehicle/trailer combination, and

wherein the sensors which detect a fault or a malfunction in the electric parking brake device (ECPB) within the scope of self-monitoring, contain at least one pressure sensor of a parking brake module (PBM) and solenoid valves of the parking brake module (PBM) for regulating pressure.
