Definitions
- the present invention relates to an arrangement of the electronic retarder control for a vehicle with a retarder according to the preamble of patent claim 1.
- the retarders are counted in addition to hydrodynamic, hydrostatic or electrodynamic brake devices arranged on the transmission, as well as systems which are provided in the form of an "Intarder" within the gearbox housing.
- Retarders are mainly used in commercial vehicles, for example, when braking from high Fahrge ⁇ speed absorb kinetic braking energy and convert it into heat, but are also well suited for required sustained braking, for example, long-term downhill.
- retarder controls are also known, which are integrated in the vehicle management system, as described, for example, in US Pat. from WO 94/27845 or EP 0953489 A2.
- EP 1 053 923 B1 discloses a hydrodynamic retarder and a device for the electronic control of a hydrodynamic retarder, the device for the electronic control of the retarder being arranged in the retarder housing.
- This integration of the controller in the retarder housing, preferably in the oil sump, proposed within the scope of EP 1 053923 B1 requires more effort with respect to the sealing and the cable feedthrough to the outside. In this case, the required cable bushings through the retarder housing make the sealing of the retarder housing more difficult and more expensive and increase the risk of leakage.
- the integration of the electronics in the retarder housing increases the complexity of the housing, which results in a higher production outlay.
- the electronics is permanently maintained at the temperature of the oil, the temperature level in the future, by raising the average coolant temperatures in the cooling circuit due to the emission and consumption optimization of the engines will increase.
- the electronics are heavily loaded by temperature peaks in the oil sump after switching off the retarder. Another problem could occur when replacing the electronics, since in this case the oil drained and the retarder must be opened, which makes disassembly or repair difficult.
- the present invention has for its object to provide an arrangement of the electronic retarder control (ECU) in a motor vehicle with a retarder, which allows very short connection paths to the actuators and sensors. Furthermore, the arrangement should enable easy repair / disassembly of the electronics and ensure clear pairing of the electronics with the retarder, such that the control on the load test stand can be tuned to the retarder.
- ECU electronic retarder control
- the electronic retarder control is advantageously housed in a separate, sealed housing and fastened to the retarder housing, wherein the fastening by screws, gluing, welding, clamping and other measures known in the art can take place.
- the housing has two separate plugs, one of the plug connectors for the wiring to the retarder or for the sensors and actuators and the other plug for the cabling to the vehicle (supply, data bus, etc.). ) is provided.
- the mounting location of the housing, in which the electronic retarder control is housed is freely selectable on the retarder housing, wherein these are particularly advantageous positions which protect the housing, For example, the top of the retarder, the position between retarder housing and heat exchanger, a recessed niche, or a position between Retarderge Reifenippen.
- the concept according to the invention achieves a clear pairing of the electronics with the retarder, since the setting of the electronic retarder control can take place on the load test stand. Furthermore, the connection paths to the actuators and sensors are very short. In comparison to the prior art, a possible repair / disassembly of the electronics can be carried out with little effort, since, for example, no opening of the retarder housing is required. In addition, the load due to vibration is significantly reduced compared to mounting on the heat exchanger.
- the inventive arrangement of the electronic retarder control is also suitable for any type of retarder.
