Abstract: An intelligent vehicle load measuring system includes a sensor installed in the shock-absorber of every wheel of a vehicle to detect the extension length data of the associating shock-absorber when the vehicle carries a load, a calculation unit coupled to the sensors to receive the extension length data of every shock-absorber of the vehicle and to calculate the weight of the load received by each shock-absorber and the total weight and loadage of the vehicle, and a display unit electrically coupled to the calculation unit to display the load data of the vehicle. The invention involves also an intelligent vehicle load measuring method.

Abstract: An intelligent fuel oil monitoring system includes a fuel level detector coupled to a fuel tank of a motor vehicle to detect the amount of the fuel oil in the fuel tank, a microcontroller coupled to the fuel level detector to receive traveling data of the motor vehicle and to establish an average speed-fuel consumption relationship curve and fuel consumption and travel distance relationship curves at different speeds and to calculate the distance the motor vehicle can travel based on the amount of the fuel oil detected by the fuel level detector subject to the fuel consumption and travel distance relationship curve, and a display unit coupled to the microcontroller and controlled by the microcontroller to display data.
