Abstract

An electric system of a vehicle including an electronically controlled braking system. The electric system has a steering angle sensor unit, at least one control module, at least one first inertia sensor and an electronic braking system central control unit EBS ECU. The at least one control module is external to the steering angle sensor unit. The at least one control module is also external to the EBS ECU. At least one of the at least one control module has mounted within it one of the at least one first inertia sensor.

First claim

The invention claimed is:

at least one control module;
at least one first inertia sensor; and
an electronic braking system central control unit (EBS ECU) of the electronically controlled brake system (EBS);
wherein the at least one control module is external to the steering angle sensor unit,
wherein the at least one control module is external to the electronic braking system central control unit (EBS ECU), and
wherein at least one of the at least one control module has mounted in it, within it or on it one of the at least one first inertia sensor,
wherein the electric system provides sensor information to provide dynamic control for an automated driving situation of the vehicle,
wherein the at least one control module includes an electronic air processing unit coupled to a foot brake module,
wherein the electronic air processing unit is coupled to service brake pressure control modules, each of which is coupled to the foot brake module,
wherein the service brake pressure control modules are coupled electrically or electronically with the EBS ECU, wherein inertia information with respect to a center of gravity of the vehicle is used by the EBS ECU to improve a functionality of EBS including dynamic stability control of the vehicle,
wherein the at least one control module has one common housing for its elements or components or has a plurality of housings directly attached to each other, in which the elements or the components are distributed among the plurality of the housings, wherein the at least one first inertia sensor is mounted within or directly on the one housing or within or directly on one housing of the plurality of housings attached to each other of the at least one control module,
wherein by locating the at least one inertia sensors in or on control modules of the electric system, the inertia information provided is captured accurately with respect to a functionality of the control module in or on which the at least one inertia sensor is located, so as to improve dynamic control of the vehicle, and
wherein the electronic air processing unit includes at least an air dryer and a multi-circuit protection valve, and wherein the electronic air processing unit forms a part of the electronically controlled brake system EBS as it provides the EBS with dried and purified process air.

2. The electric system of claim 1 , wherein a first inertia sensor is mounted in, within or on an electronic air processing unit which at least incorporates an air dryer and a multi-circuit protection valve.

3.
