Abstract: A system and method for evaluating driver performance is provided. The system includes a GPS navigation module for locating a running vehicle; a running vehicle data collection module for collecting data of the vehicle; a vehicle specifications memory for storing specifications of the vehicle; a road maps memory for storing maps of an area so as to identify the location of the vehicle by cooperating with the GPS navigation module; a road evaluation parameters memory for storing road evaluation parameters of the vehicle, and outputting evaluation parameters of the vehicle by cooperating with the road maps memory; and an evaluation module for combining the data of the vehicle from the running vehicle data collection module, the road evaluation parameters of the vehicle from the road evaluation parameters memory, and the specifications of the vehicle from the vehicle specifications memory, evaluating the combination, and outputting an evaluation report.

Abstract: A fuel-saving self-adjusting system for a vehicle engine adapted to the actual conditions of a road, including an information center and a plurality of onboard computers respectively mounted on a plurality of vehicles. Each of the onboard computers has a vehicle controlling module for adjusting a response of the engine of each vehicle so as to reduce adverse influences of improper driving manners. An optimized standard road resistance characteristic coefficient is applied as a more reliable reference to reduce the fuel consumption of the vehicle efficiently.

Abstract: A system and method of selecting optimum gear of automobile is provided. The system includes a data processor; a running vehicle data collection module; an output module; and a memory. The memory is stored with universal characteristic curve of an engine, gear ratios of a gearbox, speed reduction ratios, and a tire radius. The running vehicle data collection module collects and sends a current vehicle speed, revolutions of the engine, and an output torque of the engine to the data processor. The data processor processes the universal characteristic curve of the engine, the gear ratios of the gearbox, the speed reduction ratios, and the tire radius to determine a current gear and an optimum gear. The data processor outputs the optimum gear to the output module if the current gear is not the optimum gear. The system can select optimum gear in real time and lower fuel consumption.
