Abstract: Disclosed is a technique for ranking a driver's fuel efficiency among other drivers based on various variables associated with the environment in which the vehicle is being driven. More particularly, the present invention, selects, as a category, one or more factors affecting fuel efficiency, and, as one or more, variables another one or more. Vehicle data is then collected by a communications device which is associated with a particular trip. Next an average of the fuel efficiencies and an average of the variables for the trip are calculated accordingly the selected one more categories. The fuel efficiency of the trip corresponding to a same category for every coordinate point of the variable is then statistically processed to calculate the average of the fuel efficiency and the standard deviation of the fuel efficiency and regularized (processed as a GAP calculation) to determine the ranking of a vehicle driver.

Abstract: A diagnostic method and system is described for diagnosing an operating condition of a conductive particulate matter sensor. The sensor has a substrate with electrical resistance that varies with temperature and two electrodes on the substrate adapted to collect particulate matter between the electrodes, thereby establishing an electrically conductive path through collected particulate matter between the electrodes that can be detected by measuring electrical resistance between the electrodes, Relect. The diagnosis is performed by heating the substrate in the area between the electrodes and using the resistance between the electrodes to determine detecting whether contamination is present on the surface of the sensor. Heat may be maintained on the sensor to attempt to burn off a detected contaminant, and a subsequent resistance reading may be used to determine if the contaminant was successfully burned off.

Abstract: Wireless transmission from sensor devices included in tires is coordinated by a receiving unit associated with the tire, or transmission coordinator. In more detail, every sensor device is made aware of an overall time window available for transmission, and based on at least this information, it calculates a dedicated timeslot for the transmission of its data within such time window. This coordinated transmission makes possible a strong reduction of the probability of collisions and transmission errors, and reduces the number of transmissions, so as to comply with the limited power resources available at each sensor device.

The system may be used to improve engine operation during cold starts especially under conditions where water vapor or entrained water droplets are present in vehicle exhaust gases. In one embodiment, degradation of a particulate matter sensor is indicated after a temperature of a substrate of the particulate matter sensor exceeds a threshold temperature and an output of the particulate matter sensor is below a threshold value.

Abstract: A vehicle identifying unit obtains an identification number of a vehicle from the vehicle. A first evaluation unit evaluates a degradation state of a power storage device based on the use history of the power storage device obtained from the vehicle, using data analyzed beforehand concerning the relation between the use history and the degradation state of the power storage device. A second evaluation unit evaluates a degradation state of the power storage device using data collected when the power storage device of the vehicle is charged from a power station or when power is fed from the vehicle to the power station. A degradation determining unit determines the degradation state of the power storage device based on the degradation states evaluated by the first and second evaluation units.

Abstract: Precise operation of an accelerator operating member (7) is more difficult to perform in a reversing operation of a vehicle (1) as compared with an advancing operation. Therefore, behavior of the vehicle (1) is not smooth and thus tends to be unnatural. In the reversing operation of the vehicle (1), driving force output from an internal combustion engine (2) is limited in accordance with vehicle acceleration (D). At this time, it is possible to regulate the driving force of the vehicle (1) in conformity to the actual operation of the accelerator operating member (7) by the driver. In addition, limitation of the driving force is not executed in the advancing operation of the vehicle (1). At this time, the vehicle (1) can be driven in a state in which the driving force is comparatively small. Therefore, it is possible to prevent the behavior of the vehicle (1) from being unnatural.

Abstract: The method for generating an integrated guidance law for aerodynamic missiles uses a strength Pareto evolutionary algorithm (SPEA)-based approach for generating an integrated fuzzy guidance law, which includes three separate fuzzy controllers. Each of these fuzzy controllers is activated in a unique region of missile interception. The distribution of membership functions and the associated rules are obtained by solving a nonlinear constrained multi-objective optimization problem in which final time, energy consumption, and miss distance are treated as competing objectives. A Tabu search is utilized to build a library of initial feasible solutions for the multi-objective optimization algorithm. Additionally, a hierarchical clustering technique is utilized to provide the decision maker with a representative and manageable Pareto-optimal set without destroying the characteristics of the trade-off front. A fuzzy-based system is employed to extract the best compromise solution over the trade-off curve.
