Definitions

• Auto-driving controller either of a vehicle or of a machine
• the present invention falls into the category of electronic on-board instruments making it possible to "manage" the main driving ratios either of a vehicle or of a machine.
• the data processed is essentially oriented either towards operation or towards the adjustment of the vehicle itself: temperatures, pressures, consumption, kilometers traveled, average speeds, battery charge, tachometer, wear various ...
• the numerical character of the display is much preferable to the use of a needle on a dial and the limitation of the display to only one parameter at a time simplifies the reading.
• the measures are applied only to the vital points as well as to the operating conditions, while it is the movements of the controls by the driver which are interesting for the quality of the driving and, on the other hand, several displays. succeeding one another at a judiciously chosen rhythm on the same zone allow to multiply the interesting displays without reducing the readability at a given moment.
• Patent No. 73 21389 filed on 7-6-73 by LIP under No. 2.232.805 it details a vehicle data recording device comprising sensors, a system for processing data by sampling, a time base and memory that can be conveniently extracted for reading.
• This invention is also well suited to controlling the vehicle for a period of time immediately preceding its immobilization. It cannot be used either continuously or for measuring the driving style of a driver, which is the aim of the new invention.
• patent No. 73 26839 filed on 07-23-73 by CITROEN under No. 2,250,426 shows a device for indicating the variation of an automotive parameter, for example electric, and for alarms beyond fixed limits.
• a movable member more or less masks a witness, in proportion to the variation of the parameter.
• This device could be interesting if the parameter was a driving ratio but the complication of a movable member is great and the reading is less convenient than that of a digital display.
• the present invention makes it possible to exceed these engine data these vehicle data to provide driving elements, driver data. It aims to introduce measures of the human factor.
• the device described provides the driver with the main ratios and measures concerning the actions exerted by him on the commands available to him: steering, accelerator, brake ... It can also control by direct reading on a dashboard with digital display, and for a given route, the following ratios: - time and percentages of time during which each command will have been actuated in the "Low” range (xo to yo) , “Medium” (yo to zo) and “Door” (beyond zo), and this on the left and on the right.
• Figure 1 shows the general diagram and includes:
• FIG. 4 shows the sensor (1) of Figure 1 itself consisting of a multi-cam ring (1) with adjustable cams fixed on the steering control shaft and two contactors (2) and ( 3) offset by an appropriate angle which is, in this case, 60o (but can vary from 10o to 110 ° depending on the needs of the user and the adjustment he wishes to give to the cams and to the computer).
• the contactors are mounted on a fixed foot (4) with adjustable swivel so that the cams successively push the contacts when the control is rotated.
• the ring (1) is shown in section in (5).
• the cams are simple screws with nuts and locknuts that can be fixed in several positions on a groove around the ring. It is thus possible to fix 3, 4, 5 or more cams at precise points and to detect their passage either on one or on the other of the contactors.
• Figure 3 details in (1) the two other sensors (2) and (3) of Figure 1, identical, also mounted on fixed feet (2) with adjustable ball joint, comprising contactors (3) with three actuated positions l '' either by the pedal or by the accelerator lever and the other either by the pedal or by the brake lever.
• Each of these two commands therefore has a first minimal displacement range giving rise to no measurement, then, as it travels, it closes the first position of the contactor corresponding to the "Low” action range, then the second position corresponding to the "Medium” range and finally the third corresponding to the "Strong” range.
• each range depends on the spacing of the contactor blades at rest but also on the position of the triple contactor with respect to the pedal, position adjusted by means of the ball joint foot.
• the computer (4) in Figure 1 is specially wired to receive, decode and process the electrical pulses from the sensors. It determines on the one hand the direction and the range of rotation of the steering shaft at a given instant and on the other hand in which range either "Low”, “Medium” or “High” are each of the contactors on the controls, acceleration and braking.
• Figure 4 details the digital results display board marked (6) in Figure 1. It gives successively by flashing a few seconds for each number the ratios previously listed. Thus follow one another on the same line:
• the button (4) determines the sequence of the display, by pointing to the first criterion and pressing the button (5) to save this first criterion, then pointing the second criterion and pressing the button (5), then the third criterion and so on.
• the switch marked A and M allows switching on by lowering it and on the other hand, by raising it, the device is stopped, which at the same time resets all memories to zero.
• the button (2) sets the duration of display of each data according to the goal sought by the user. To do this, turn the button (2) to the desired duration and press the button (3) to save your choice before the start of the measurements.
• the button (2) also makes it possible to display the first digit of the first pre-displayed standard ratio which is recorded by pushing the button (6), then the second digit in the same way and possibly a third if this first ratio - standard includes three digits. Then push the button (6) twice and start again to record the second standard-ratio by entering it digit by digit on the button (5) and saving it by pushing the button (6), and similarly for the third.
• the three lamps of different colors (8) and (9) light up when the actual ratio measured at a given time is either above or below the corresponding pre-displayed standard ratio.
• the invention described can be used either for learning or for the improvement of driving or automobile, or air, or of various machines, for the improvement of sporty driving or more simply to achieve energy savings and material in daily driving on routes known or measured by others. It applies equally well to learning and perfecting the operation of public works machinery, cranes, overhead cranes, agricultural equipment ... We learn to handle them with the minimum of fatigue and fuel and machine wear. It can be very beneficial for the rehabilitation of disabled people to all these types of conduct.
