Definitions

  • the present invention relates to a gear feedback system according to the preamble of the independent claim.
  • the driver has, by his/her way of conveying the vehicle, the greatest influence, both from an economical and from an environmental point of view. It may thus be difficult for a driver to determine which gear that is optimal from a fuel consumption view in different situations. There are often at least two, from a rotational speed-perspective, suitable gears to choose from when the vehicle is conducted. The difficulty for the driver is to know which one of these gears that will make the motor work in a most efficient way and thereby also in the most economical way.
  • a gear shift indicator to indicate which gear that is the most suitable from a fuel consumption point of view. See e.g. the teaching indicator for efficient vehicle gearshift operation disclosed in the US patent 4,439,158, or the device to provide an indication to the driver whether a gear change should be made to obtain a better fuel consumption, disclosed in the GB patent application 2,084,524.
  • the indicator may be visual information to the driver in the meter display area, in the shape of e.g. a number indicating the preferred gear, or as a preferred rotational speed, e.g. as a green stripe at the tachometer that indicates suitable number of revolutions.
  • the object of the present invention is to further encourage the driver to convey the vehicle in an economically and environmentally friendly way.
  • a further aim is to give the driver, or a third part, the possibility to evaluate the driver's way of using the gears.
  • a gear feedback system for use in a vehicle according to the invention, comprising a gear recommendation means adapted to determine an optimal gear value in dependence of various influencing parameters, e.g. weight of the vehicle, velocity, rotational speed, road topography, and based upon said optimal gear value to recommend an optimal gear of the vehicle, a gear sensing means for sensing a currently used gear and to determine a used gear value in dependence thereto.
  • the system further comprises an evaluation means to analyse and grade the presently used gear, by comparing said currently used gear value with the optimal gear value and based on the comparison generate a grade, and a presentation means to present said grade to the driver of the vehicle.
  • the present invention gives the driver a tool to use in his/her strives to be the "best driver", and also provides the possibility for the driver to feel more secure knowing that he/she is driving with the most economically and environmentally friendly gear for the moment even if the vehicle in question has a manual gear box. Furthermore, the grading of the gear choice gives the driver a possibility to follow- up if he/she has improved his/her ability to use correct gear in different situations and terrain.
  • Figure 1 schematically illustrates a control system for a vehicle where the present invention is utilized.
  • Figure 2 illustrates an example of a system according to the present invention.
  • Figure 3 illustrates an example of a presentation means according to the invention.
  • the present invention is applicable to motor vehicles provided with a manual mechanical transmission having a basic gear box and optionally at least one secondary gearbox, such as a range gearbox or a split gearbox.
  • a manual mechanical transmission having a basic gear box and optionally at least one secondary gearbox, such as a range gearbox or a split gearbox.
  • Especially heavy motor vehicles such as trucks, towing vehicles and busses mostly have both a split gearbox and a range gearbox.
  • “gearbox” is here to be interpreted broadly and the split part, the basic or main part and the range part of the transmission may be enclosed in the same gearbox housing.
  • the present invention is in particular applicable to heavier vehicles, but may also be used in any motor vehicle, e.g. private cars, tractors etc.
  • a control system for a vehicle with which the present invention can be utilized comprises a front shaft 1 with steering wheels 2, 3, a rear drive shaft 4 with driving wheels 5-8, and optionally a rear shaft 9 with wheels 10 and 11. Furthermore, the vehicle contains an engine 13 connected to a gear box 12, which drives the drive shaft 4 by means of an output shaft 14 from the gear box. Gear box 12 and motor 13 are controlled by control units 15, 16, respectively, which are controlled by a main control unit 17.
  • the Engine Management System (EMS) 16 controls the motor functions of the vehicle, which, for example, can consist of fuel injection and motor-brake.
  • the control is based on a number of input signals, which can consist of signals from (not shown) throttle controls (the position of the accelerator pedal), speed sensor and brake management system.
  • the Gearbox Management System (GMS) 15 controls the gear functions, wherein, when using an automatic gearbox, the gear shifting can be controlled based upon an input signal from speed sensors. In manual gear shifting, the shifting can be controlled from an input signal from a gear selector (gear shift lever), and no GMS may be needed.
  • the vehicle contains a Brake Management System (BMS) with a break control unit 17, which controls the brake functions of the vehicle, such as automatic calculation of the load so that a given pedal position always can result in the same brake effect regardless of the load.
  • the brake control unit controls the various brake systems of the vehicle, e.g. retarder and other supplementary brake systems, exhaust brake and service brake on the basis of commands from the driver, and sends control signals to system modules (not shown) dispersed on the chassis, where electrical control signals are used, e.g. to adjust brake pressure.
  • control units constitute mere examples of what can exist in a vehicle. As is appreciated by a person skilled in the art, two or more of the above described control units can, of course, be integrated into one single control unit.
  • the present invention relates to a gear feedback system 18 including a gear recommendation means 19 to determine an optimal gear value of the vehicle in dependence of various influencing parameters, e.g. weight of the vehicle, velocity, rotational speed, road topography, and based upon said optimal gear value to recommend an optimal gear of the vehicle.
  • the gear feedback system 18 is preferably arranged in a vehicle.
  • Each gear range is most efficient to operate at different pre-selected ranges of vehicle operation, and the selection of which particular gear range that will operate the vehicle most efficiently is determined in relationship to which power that is needed to convey the vehicle. Necessary power that is needed to convey the vehicle in constant speed is momentary calculated from the driving resistance.
  • the driving resistance of the vehicle may be established by means of a suitable calculation model based on different parameters of the vehicle, such as engine load, engine rotational speed, vehicle speed, road inclination and aerodynamic characteristics, see e.g. WO/2007/139491 , in a manner well-known to a person skilled in the art. If the vehicle accelerates, this acceleration contributes to an increased power demand of the vehicle and is accounted for when determining which gear that is most suitable.
  • P(driving_resistance) is the power needed to convey the vehicle in constant speed
  • P(acceleration) is the power needed to accelerate the vehicle to a certain acceleration
  • the gear which best corresponds to the required total power is recommended to the driver.
  • the gear recommendation means 19 accordingly constantly senses the various influencing parameters, e.g. weight of the vehicle, velocity, rotational speed, road topography, and constantly calculates a required total power and compares the required power with the different gear intervals to check which gear that is the most optimal. If there is another, higher gear with a better rotational speed economy, which may contribute with necessary power to maintain the velocity, this gear is recommended instead. There is always a demand that recommended gear has to be in a certain dynamic rotational speed interval, depending on the conditions, to prevent recommending gears that otherwise would involve a too high or too low rotational speed of the motor.
  • various influencing parameters e.g. weight of the vehicle, velocity, rotational speed, road topography
  • the gear feedback system 18 further includes a gear sensing means 20 for sensing a currently used gear and to determine a used gear value in dependence thereto.
  • an evaluation means 21 analyses and grades the currently used gear, by comparing the currently used gear value with the optimal gear value and based upon the comparison generate a grade.
  • the generated grade is presented to the driver of the vehicle on a presentation means. Accordingly, the driver is encouraged to use the recommended gear, as the driver knows that the presently used gear is being graded.
  • a potential effect of the grading of the driver is that different drivers may start to compete between each other in the ambition to be the "best driver".
  • the presentation means is according to one embodiment placed on the driver's panel, well visible for the driver when conveying the vehicle.
  • the presentation means may also be in the shape of an additional display in the driver's compartment.
  • the system 18 is illustrated in fig. 2, which includes means 22 for receiving relevant signals regarding surrounding parameters and signals from internal sensors in the vehicle, i.e. speed sensors, torque sensors, gear sensors etc, used in the gear recommendation means 19 to determine a recommended gear and in the evaluation means 21 to calculate a driver's gear grade.
  • Preferably positive grades are given to the driver when the driver has chosen the optimal gear for the situation, or has chosen a gear that is within a certain rotational speed interval
  • the grade depends on the time using a non- optimal gear, such that the grade is decreased if the non-optimal gear is used longer than a dynamic time duration.
  • the feedback system then includes a time sensing means to start measuring the time with a time clock when it was determined that the driver was driving with a non-optimal gear. When this measured time exceeds a dynamic time duration, the grade is decreased. Thus, a decreased grade is given to the driver if he/she has driven the vehicle with a non- optimal gear for a certain time.
  • the grade depends on the time using an optimal gear, such that the grade is increased if the optimal gear is used longer than a dynamic time duration.
  • the feedback system then includes a time sensing means to start measuring the time with a time clock when it was determined that the driver was driving with an optimal gear. When this measured time exceeds a dynamic time duration, the grade is increased. Accordingly, the driver is rewarded if he/she maintains the optimal gear.
  • the driver obtains an increased grade if he/she has chosen this gear. If the driver instead uses the 9 th gear a recommendation is given to the driver where he/she is encouraged to shift gear to the 10 th gear. If the driver anyway chooses to continue with the 9 th gear, his/her grade is started to be lowered after a certain dynamic time. If the driver instead would drive with the 12 th gear (the highest gear) in 85 km/h, where gear 12 also is the recommended gear, the grade is either decreased or increased. This because a gear shift down to the 11 th gear would cause the rotational speed to be outside the rotational speed interval.
  • These embodiments are exemplified with a gear box with twelve (12) gears, but other kinds of gear boxes with less or more than twelve (12) gears are of course also practicable within the scope of the invention as defined by the appended claims.
  • the grade is presented at the presentation means at time periods decided by a presentation manager being an integrated part of the presentation means.
  • the grade may also be presented as a change of grade.
  • the presentation manager determines the time periods in dependence of the relation between presently used gear and optimal gear. For example, if a driver uses a non-optimal gear longer than a dynamic time, then the grade is decreased after the dynamic time and the change in grade is presented at the presentation means.
  • the grade is constantly presented at the presentation means. The driver then continuously can see how good he/she is at using the gears.
  • the gear recommendation means 19 recommends an optimal gear to the driver, if a non-optimal gear is used longer than a dynamic time duration. Accordingly, recommendations about a preferred gear may be given to the driver when the driver has been driving with a non-recommended gear for a certain dynamic time.
  • the gear recommendation means 19 then includes a time sensing means to start measuring the time with a time clock when it was determined that the driver was driving with a non-optimal gear. When this measured time exceeds a certain dynamic time duration, a recommendation is shown to the driver.
  • the recommended optimal gear is presented at the presentation means. The recommended optimal gear may be presented on a display in numbers together with information about which action that is to be done, e.g.
  • the grading of the driver may be presented on the same display, or may be presented in another area or display.
  • the dynamic time until a recommendation is given may also depend on how many steps away from a recommended gear the driver has been driving, i.e. current gear minus recommended gear.
  • the presentation manager may decide time periods e.g. in dependence on when a recommendation has been presented on the presentation means.
  • the dynamic time is, according to one embodiment of the invention, also dependent on how important it is to make a gear shift. For example, if a driver demands a large torque from the motor e.g. in an uphill slope, the duration of the dynamic time is reduced to give a recommendation faster to the driver to change gear. Another example is if the driver greatly decreases the velocity of the vehicle in a short time. Then the dynamic time should also be reduced, to be able to give a fast recommendation to the driver. Accordingly, in one embodiment, the dynamic time duration depends on different gear- and/or energy criteria. Thus, the relationship between demanded power to maintain the speed and available power influences the time periods. If the demanded power is more than the available power, the dynamic time may be shorter to encourage the driver to change gear earlier.
  • the dynamic time may be dependent on various parameters, e.g. brake energy, demanded motor energy, inclination of the road, velocity, rotational speed etc.
  • Gear recommendations are not shown if the driver takes out a too high torque from the motor (typically at acceleration), with exception for if the driver accelerates with too low gears and is not using the total rotational speed spectrum, i.e. is driving in an uneconomical way, which may be the case if a driver e.g. accelerates in an uphill slope.
  • a presentation means may look like is shown in fig. 3.
  • Recommendations are shown in the centre of a display as a gear number in brackets, optionally together with information about which action that would accomplish the recommended gear.
  • Grades may be shown as stars that are illuminated or faded when a grade change occurs. For example, initially, the recommendation is shown with belonging action without stars. If the driver chooses to not follow the gear recommendation, the stars are illuminated (five grey stars means that the gear grade at the moment is about to be lowered). In the cases when the driver uses the correct gear nothing is shown (the grade is increased in the background).
  • the determination of optimal gear is influenced by an estimated gear shift time.
  • the time it takes for the driver to conduct a gear shift when driving the vehicle is estimated. This time depends inter alia on the type of gear box and which type that is needed to end up on the recommended gear (whole step-, split- or range gear). Accordingly, it is possible to make a reasonable determination if the potentially recommended gear still will be the best after the gear shift has been made.
  • the system 18 further includes all necessary computer programs and hardware to perform the necessary steps to give feedback to the driver according to the present invention.
