Definitions

  • This Patent of Invention as indicated by its title, relates to "AN IMPROVED CENTRAL CONTROL UNIT FOR INJECTION ENGINE-­POWERED VEHICLES AND OPERATING SYSTEM THEREFOR".
  • the incorporation of the central control unit in the vehicle entails the supply of selective information, at the discretion of the driver, on distance travelled, current speed, average speed, prior consumption, current consumption, average consumption, distance before next maintenance, consumption before next maintenance, maintenance performed and pending performance, recommended optimum engine speed, clock, alarm and calendar.
  • This central control unit is composed of a supply unit, a sensor input unit, a function selector keyboard, a micro­computer, a display and alarm unit, a storage and timer unit, and a supplementary unit.
  • the supply unit which is protected against electrical inter­ferences, transforms the voltage from the battery of the vehicle to the voltage required to energize the micro­computer.
  • This unit is automatically connected and dis­connected thanks to the programming of the microcomputer or to the signal from the ignition key. It constantly supplies the storage and timer unit in the same way in order to prevent loss of the stored data, even without the ignition key and even without battery in the vehicle, and in order to keep the clock on time and the calendar up to date.
  • the storage and timer unit In addition to supplying electric power to the storage and timer unit and to the microcomputer, it also supplies the display and alarm unit, which features the conventional components to allow display of all data and alarms.
  • the sensors which are connected to different points of the vehicle, send the respective signals to the sensor input unit so that they may be interpreted by the microcomputer.
  • the parameters measured by the sensors are: input and return volume of injection pump, distance travelled by wheels, engine rpm, accelerator position.
  • the storage and timer unit provides protection against loss, due to failure of electric power supply, of the most significant data that one wishes to maintain from one start-up to another. It also provides the data on current time and calendar date, and starts up the system, in the case of disconnection, when the time on the alarm concurs with that on the clock, as long as the alarm is activated. It also provides a signal of good operation to supply the supplementary unit.
  • the function of the supplementary unit is to protect the good operation of the other units, picking up data from them, and in the case of a breakdown of any of the com­ponent assemblies of the central control unit, this supplementary unit is activated and informs the microcom­puter.
  • the microcomputer is the real intelligent unit of the system, interpreting the input signals from both the sensors and the keyboard, providing as a result, depending on the program and on the calculating process, the value of the variable desired by the user, sending the respective signal to the display and alarm unit.
  • the microcomputer has the capacity to itemize and interpret the distance travelled as a total or partial sum, the prior consumption in the same way, the current consumption in liters/hour or in liters/100 km.
  • Figure no.1 is a schematic diagram of the central control unit with its component units and the way in which they are connected.
  • the central control unit (17) is composed of these units: supply unit (10) of the microcomputer (13), sensor input (11), keyboard (12), display and alarm (14), storage and timer (15) and supplementary unit (16). All the sensors coupled to the different systems of the vehicle are con­nected to the central control unit (17) and, more specific­ally, to the sensor input unit (11).
  • the central control unit (17) In order for the central control unit (17) to operate, it requires the power supplied by the supply unit (10) to the microcomputer (13), and to the display and alarm unit (14) and the storage and timer unit (15).
  • the microcomputer (13) receives the signals picked up by the sensors through (11) and analyses them on the basis of the internal program, performing calculation processes in the required cases, then sending the signal to (14), which displays the parameter detected by the sensors.
  • (13) can be activated by the user of the ve­hicle through the transfer unit (12) so that (14) will immediately display the respective functions such as di­stance travelled, both total and partial, prior consumption in the same way, current consumption in liters/hour or in liters/100 km, current speed, average speed, distance be­fore next maintenance, consumption before next maintenance, information on maintenance performed and pending per­formance, recommended optimum engine speed, clock, alarm and calendar.
  • the supplementary unit (16) which acts in the case of external interference, or in the case of malfunctioning of the other component units of the central control unit, storing the pertinent data.
  • the central control unit specified by this Patent of Invention is extremely simple and, at the same time, efficient, which are factors of importance as concerns the safety of both the vehicle and the driver.
