Device for monitoring the process of driving a vehicle

摘要

Device for monitoring the process of driving a vehicle consisting of at least the following:
a first means of processing a signal; a second means of detecting the vehicle movement; a means for providing an HMI type of interactive display of information for the user; and a means configured for knowing the consumption characteristics of the vehicle and its technical characteristics as far as optimum theoretical behaviour;where the means for processing are configured for calculating the optimum consumption according to the characteristics of the vehicle, establishing the driving parameters required for equating the actual consumption to the optimum consumption, displaying this information to the user in the means available for display.

1. A device for monitoring the process of driving a vehicle optimizing the fuel consumption in which an interactive and real time monitoring of the driving is achieved without a connection with a center that governs the vehicle; said device comprising:
a) a vehicle movement detector; b) a database in which technical characteristics of the vehicle are listed, the technical characteristics including: weights, number of cylinders, engine position, cubic centimeters, diameter stroke, valves per cylinder, type of engine fuel supply, HP/RPM, Torque (Nm)/RPM, type of traction, gearbox, miles per gallon in urban, off road and mixed driving, CO2 emissions, suspensions, and brakes; c) a display comprising an HMI interface comprising a menu that includes, at least:
i) a selector of the level of consumption selected between basic saving mode, average saving mode or maximum saving mode; andii) a selector of the level of occupancy between maximum or minimum level of occupancy; andiii) a selector of a vehicle from the database in which the device is used; and d) a global positioning system; wherein the device comprises a processor configured to:
i) calculate an optimum consumption according to the technical characteristics of a vehicle selected from the database;ii) calculate a current gear of the vehicle in real time for equating the vehicle consumption to the optimum consumption as a function of a technical specification of a vehicle selected from the database wherein the speed in which the gear change must be carried out is calculated according with the following formula:
Speed in which the gear change must be carried out=speed of the vehicle*(1+((5*(level of occupancy−1))/100+((5*(3−level of consumption or saving mode))/100))a) wherein the speed of the vehicle is provided by the global positioning system;b) wherein the level of occupancy is selected by the user in the HMI interface; andc) wherein the level of consumption or saving mode is selected by the user in the HMI interface;iii) calculate an estimated safety distance with respect to other devices; andiv) calculate an anticipation distance according with the following formula:
anticipation distance=(radius turn gear*(speed of the vehicle/10))2−inertia−engine resistance;wherein the inertia is the variations in inertia when driving in sloped roads and wherein the radius turn gear and the engine resistance represents the deceleration of the vehicle without stepping on the brake;and wherein said gear, said safety distance and said anticipation distance are provided to the user by means of the display.
