Definitions
- the invention relates to a force measuring arrangement for processing force signals in electronic brake systems, in particular vehicle brake systems of a force sensor assembly and a signal processing device, wherein the force sensor assembly comprises a brake actuator and at least one pressure member, wherein on the pressure member an amorphous diamond-like carbon layer is applied as a force sensor.
- EMB electromechanical brake systems
- a modification of this full EMB system is the hybrid brake, in which the front axle is still hydraulically braked in a conventional manner, but the rear axle already contains the EMB actuator system including electric parking brake. For this purpose, only a simple electrical system is necessary because the hydraulic system is the legally prescribed second brake circuit.
- Previously known sensor systems are not suitable for this task.
- An example is in the DE 103 08 798 Al describes where a pressure measuring arrangement for the redundant processing of pressure signals in electronic brake systems and their use is disclosed.
- a sensor module is described consisting of a plurality of electrical pressure measuring elements, which are arranged together on a membrane.
- the known versions of Bremskraftmesseinrich- tions in vehicle brakes are thus either indirectly measuring systems by z. B. the hydraulic pressure with the help of z. B. membrane-type sensors is measured, or sensors are used according to the strain gauge principle, which provide the deformation (elongation or compression) of a pad, usually a specially shaped sensor receptacle.
- the known solutions are discrete strain gauges which are adhesively bonded to the base bodies and thus require a great deal of calibration effort.
- Another disadvantage is the lack of system rigidity (deformation is required in DMS) and the poor integration into miniaturized and low-mass brake systems.
- a force measuring arrangement which has at least one force sensor assembly, wherein the force sensor assembly consists of at least one brake actuator and a pressure member in frictional connection, wherein on the pressure member at least one amorphous carbon layer is applied, which acts as a force sensor.
- Temperature sensor • Excellent tribological property, corrosion-resistant
- the measurement of the actual force is made by means of a resistance measurement, which is carried out through the layer and which also allows static measurements over an extended period of time.
- a resistance measurement which is carried out through the layer and which also allows static measurements over an extended period of time.
- the amorphous carbon layer Due to its hardness (15-40GPa) and a measuring principle acting in the layer normal, the amorphous carbon layer enables a low-mass and completely rigid measuring arrangement. This makes it possible to use a force sensor in z. B. rotationally symmetric disc shape for this application, which is integrated in brake systems, without the Stiffness and dynamics of the system are adversely affected. Furthermore, the coating is extremely wear-resistant and corrosion-resistant, so that it has an excellent suitability for the demanding application in vehicle brakes.
- the force measurement is carried out in this thin-film sensor by a change in the electrical resistance and preferably in the layer normal. In this respect, the diamond-like sensor layer can be integrated directly into the power flow of the brake actuator.
- the amorphous carbon layer forming the force sensor is preferably a diamond-like carbon layer known as a: CH, i-CH, Me: CH, DLC and Me: DLC.
- the amorphous carbon layer can have graphitic structures with sp 2 hybridization in combination with diamond-like structures with sp 3 hybridization.
- the layers may be provided with metallic and / or non-metallic doping elements. Such a layer is described in DE 199 54 164 A1. For this reason, reference is expressly made to the entire disclosure content of this document.
- the production of the amorphous carbon layers which are used according to the invention can be carried out by means of conventional PVD and / or plasma CVD methods or by a combination of both methods.
- Commercially available sputtering equipment or plasma CVD equipment can be used for this purpose.
- the amorphous carbon layers according to the invention preferably have a hardness of approx. 20 GPa and are used in the thickness range of 1 to 10 microns.
- a pressure component in the force sensor assembly according to the invention a pressure plate, cylinder, disk or ring is preferably used.
- all component parts of a brake actuator which are in the force flow are suitable.
- the temperature of the sensor and thus of the brake actuator can also be measured to increase the safety of the brake system.
- the temperature measurement serves on the one hand to compensate the temperature characteristic of the force sensor but also to control and optimize the actuator control.
- the temperature measurement with the aid of the amorphous carbon layer can be carried out in such a way that the resistance of the layer is measured at a location that is thermally equivalent but not in the force flow.
- Conducted solutions can be used to connect the force and temperature measurement. These are z. B. the thin-film electrodes provided with a conductor track and a bonding pad and then connected in a known manner with a wire by bonding or soldering or gluing. The contact surfaces can be protected later by a potting compound.
- Another embodiment of the invention consists in an integrated evaluation circuit by z. B. an ASIC or other microelectronic components are applied directly to the force sensor, ie to the amorphous carbon layer or a suitable component of the braking system which also carries the amorphous sensory coating.
- the connection of the force sensor or local subdivision of the Sensor takes place with the aid of a thin-film circuit or in a known manner with wire bonding / soldering, gluing.
- the invention further relates to the use of an amorphous carbon layer as a force sensor for vehicle brake systems, in particular electromechanical brake systems.
