Abstract: A system for monitoring the operation and maintenance of vehicles. The system comprises a plurality of sensors attached to various vehicle modules that need to be monitored. The sensors are operatively connected to a control module, which in turn is operatively connected to a scheduler and to a communication module. Upon operation, the sensors present the control module with indicators relating the current operation of various modules of a vehicle. The scheduler presents the control module with user-defined schedule of operation and maintenance of said vehicle. The control module performs a matching between the schedule and the sensor indicators and alerts the user via the communication module of any mismatch between the indicators relating the current operation of various modules of a vehicle and said user-defined schedule of operation and maintenance of said vehicle.
