Definitions
- a brake preferably a disc brake
- the present invention relates to control electronics integrated in a brake, preferably a disc brake, according to the preamble of claim 1.
- Control electronics integrated in a disc brake are known, for example, from DE 197 56 519 AI. With such control electronics, brake-specific parameters can be recorded and brake components can be controlled and / or regulated. This includes, for example, the operation of an electromechanical wear adjustment system.
- the control electronics function via an external power supply. Via an appropriate connection, such as. B. a CAN bus connection, the control electronics is able to exchange information with other vehicle systems.
- Control and monitoring systems are being used to an increasing extent in order to record and evaluate vehicle-specific or vehicle operation-specific data.
- sensors such as tire pressure sensors, wheel force sensors, wheel speed sensors or the like are also arranged on the vehicle wheel, by means of which specific parameters are determined and are preferably transmitted to corresponding receiver and evaluation units without contact.
- So-called “near-field telemetry systems” are used for contactless transmission, in which the sensor arranged on the vehicle wheel is operated passively. The sensor does not have its own energy source, but is only equipped with a coil that is transmitted by a transmitting and receiving device stationary evaluation and
- Control device is excited with electromagnetic pulses for transmission of the measurement signal.
- it is also known to excite the coil acoustically or optically (DE 10044 266 AI).
- Interrogation signal sent by which a capacitor is charged in the sensor.
- the sensor is operated via the energy stored in the capacitor.
- addressing by coding is required, several sensors are operated by the receiver evaluation electronics.
- the addressing can be done by coding in the signals for query and response or by using different frequencies for the individual sensors.
- the stationary evaluation and control device requires all elements of an electronic device, such as a power supply, a signal line or a CAN bus connection, a protective housing with cabling and / or plug connection and the like.
- the present invention is therefore based on the object of further developing control electronics of the generic type in such a way that their functionality is expanded.
- control electronics which have the features of claim 1.
- control electronics means that, in addition to the electronic components for the monitoring and control of the disc brake or brake-specific components, the electronic components, i.e. transmitter / receiver units for the sensors, can be combined to form a unit that is available for the monitoring of non-brake functional parts or functions are.
- the assembly is also simplified, since only one control electronics is now to be installed, which not only results in a cost reduction, but also a reduction in the susceptibility to faults, which is correspondingly greater in a plurality of structural units than in a single one.
- the space requirement is minimized, which is a constant target, particularly in vehicle construction, which is optimally achieved by the invention.
- the sensors can obtain their operating energy from an integrated energy source, for example a battery.
- a particularly advantageous embodiment of the invention provides that the sensors are operated by means of the telemetry system known per se, in which the energy of the transmission signal of the transmitter / receiver unit integrated in the brake is used.
- control electronics By using only one control electronics for all sensors installed in the wheel area and the consequent omission of separate control electronics, the cabling for their power supply and signal transmission is eliminated, as is a housing with plug connections, sealing and fastening, power supply, surge protection and other electronic components.
- the transmitter / receiver unit of the telemetry system can be combined with the existing brake control electronics and preferably installed on the existing circuit board.
- the arrangement of the transmitter / receiver unit is selected such that interference-free reception of the sensor signals is made possible.
- a disc brake is shown, as it is shown and described in principle in WO 02/14708 A2.
- the disc brake has a brake caliper 1, which comprises a brake disc 3 in its upper peripheral region.
- Sliding brake pads 4 are assigned to the brake disk 3 on both sides, each having a pad material 4b applied to a brake pad carrier 4a.
- the brake caliper 1 is fastened to a fixed axle flange 5 and is therefore immovable. It is a so-called fixed saddle.
- an application device 6 is provided on one side in the brake caliper, which can be actuated by means of a pneumatically operated brake cylinder 7. This presses the right brake pad 4 here against the brake disc 3 and then the brake disc 3, which is displaceably guided on the axis, against the opposite, brake pad 4 on the reaction side.
- Each brake pad 4 is assigned an adjusting device 8 which can be driven by an electric motor and by means of which the brake pads 4 are readjusted due to wear.
- the adjusting devices 8 are operatively connected to control electronics 9, which is an integral part of the disc brake, here arranged on the outside of the caliper 1 and in the present exemplary embodiment is firmly connected to the caliper 1.
- the control electronics 9 have a power supply 10 and a data connection, not shown, for example, a CAN bus connection for exchanging information with other vehicle systems.
- the data can also be transmitted wirelessly via transmitters and receivers, not shown here
- the disc brake and thus the control electronics 9 are arranged on the inside of a wheel 12 which has a hub 11, a rim 13 and a tire 14.
- At least one transmitter / receiver unit 9b is provided in the control electronics, which is in operative connection with at least one non-brake wheel-specific or near-wheel sensor.
- tire pressure sensor 15 and speed sensor 16 which can be provided with their own power supply, for example a battery or, as already mentioned, can be operated by means of a telemetry system.
- wheel-specific or near-wheel sensors with which, for example, the wheel bearing temperature, the acceleration, a vehicle inclination, a distance or a
- Brake disc temperature can be determined, an ultrasonic or radar distance sensor being used for determining the distance.
- the assigned transmitter / receiver unit 9b is located in the control electronics 9, and a common transmitter / receiver unit 9b, preferably mounted on a common printed circuit board 9a, can be provided for all sensors. In this case, the signals emitted by the sensors are appropriately addressed or coded.
