Automated processes can reduce costs and save time. For this reason MANN+HUMMEL is working on a comprehensive software solution including sensor technology to monitor the filter status and as a result is setting standards when it comes to predictive maintenance.

Information on the status of their vehicles is a valuable asset for the fleet operators of agricultural machines, construction machines and heavy duty commercial vehicles. The smooth operation of their vehicles is only possible if the vehicles are properly maintained. But when is the right moment to carry out a service? Instead of relying on experience, intuition or fixed intervals, the method of predictive maintenance is increasingly establishing itself. There are many advantages to proactive measures compared to reactive measures. Maintenance times can be arranged precisely to fit in with the machine schedule and therefore it is possible to reduce or even eliminate unplanned downtimes. This has a positive effect on the efficiency of the vehicles and in turn reduces the total cost of ownership. The software solution to monitor the filter status makes MANN+HUMMEL the first manufacturer to offer networked filtration as an integrated component of comprehensive telematics systems used in fleet management.

Everything at a glance

Various sensors monitor the load status of air and cabin air filters, oil, hydraulic oil and transmission oil filters as well as fuel pre-filters and main filters. Furthermore, the status of the engine oil, hydraulic oil and fuel can be observed. The measured data is transferred from the respective vehicle to the OEM cloud where it is anonymized and then passed on to the MANN+HUMMEL cloud. Algorithms analyze the data of the individual sensors and determine precise key figures for the predictive maintenance. This information is prepared and returned digitally to the OEM which makes the information conveniently available to end customers, fleet operators and users in the telematics system or via an app. The advantage for the operator is that he is able to view the status of his vehicle fleet at all times. Numerous key figures provide the operator with information on the exact condition of the fleet vehicles and indicate upcoming maintenance and repair work for individual components. Up to now fleet operators have had to determine the filter status by time-consuming visual inspection which could lead to an incorrect assessment or alternatively fixed servicing periods are maintained. The use of the software solution from MANN+HUMMEL ensures that the filter is always changed at the right time. The filter service life can be efficiently exploited under consideration of changing operating conditions. Monitoring in real time protects against incorrect servicing for example due to a filter change made based on intuition or habit. Apart from that, the risk of exceeding the service life can be eliminated. Therefore, unplanned downtimes and failure in the field can be prevented. That saves time, reduces costs and ensures the longest possible service life for the filter.

 

Small cost, big benefit

MANN+HUMMEL has been collecting experience on predictive maintenance since 2017 when the company introduced the Senzit air filter monitor as a retrofit solution for agricultural and construction machines. In 2018, at the CES in Las Vegas Senzit was selected to be ’Innovation Award Winner’. The experience gained in the development and practical use of Senzit enabled the integration of predictive maintenance into a wider range of filters. In addition to the complete solution, in future on request MANN+HUMMEL will offer vehicle manufacturers customized and integrated solutions. The first customer pilot projects are planned for 2020 – and that will be just the first step. The development of self-monitoring systems and components is ongoing.
