An indicator is provided in a vehicle for indicating necessity of change of a fuel vapor absorber in a venting line of a vehicle tank, especially a methanol tank for fuel cell vehicles.

A processor may receive an input dataset. The input dataset may be associated with a plurality of vehicle components and one or more performance factors of the recreational vehicle. A processor may generate a digital twin of the recreational vehicle using the input dataset. A processor may simulate, using the digital twin, an impact of one or more conditions on the recreational vehicle. The simulating may include a prediction having one or more predicted conditions associated with the recreational vehicle.

In a motor vehicle accident data memory and method of operating it, a reference time is determined by a satellite navigation system, and a system time is synchronized with the reference time. When an accident is detected, accident data and the system time are recorded in a non-volatile memory.

Embodiments herein relate to vehicle filter monitoring systems and methods. In an embodiment, a filter monitoring system is included having a filter sensor device configured to generate data reflecting a filter condition value of a filter and a geolocation circuit configured to determine a present geolocation of a vehicle. The system can also include a system control circuit configured to generate or receive local contaminant concentration values at the present geolocation, evaluate the filter sensor device data to determine at least one of the filter condition value and a change in the filter condition value, and generate at least one of a maintenance recommendation and a routing recommendation based on the local contaminant concentration values, time spent at the geolocation of the vehicle, duty cycle of the vehicle, the filter condition value, and a change in the filter condition value. Other embodiments are also included herein.

A method detects a manipulation of an exhaust gas system, in which measured values are sent to an external checking unit by a control unit of the exhaust gas system. In the external checking unit, an evaluation of the exhaust gas system as “manipulated” or as “not manipulated” takes place. Model values are formed in the control unit, which are at least partially formed from the measured values which are sent to the external checking unit. The external checking unit takes the model values and the measured values into consideration in the evaluation of the exhaust gas system.
