Definitions

  • the invention relates to a method and system for operating a motor vehicle and to a motor vehicle having such a system.
  • the mode of operation of the electric motor of the hybrid vehicle is selected as a function of the route data and taking into account a state of charge of an energy storage of the hybrid vehicle.
  • An operating strategy for operating the hybrid vehicle is predefined by specifying a geographical travel destination and / or a destination parameter of the operating strategy, one of these travel routes being selected taking into account the operating strategy when alternative travel routes are available.
  • DE 103 06 093 A1 shows a method for determining an optimal fuel consumption and a warning system for warning a driver when there is not enough fuel to reach a desired destination. Fuel consumption is calculated and the driver is warned if there is not enough fuel to reach a gas station on the way back from the desired destination.

  • an input device is provided, via which some of the vehicle operating parameters can be manipulated during operation of the motor vehicle.
  • the method according to the invention for operating a motor vehicle comprises the following steps:
  • each measure is continuously assessed for its impact on the resulting reduction in consumption;
  • ⁇ each measure is continuously assessed for its impact on a driver's restriction of the motor vehicle;

  • the destination input can be done, for example, in a vehicle-side navigation device, wherein the energy required to achieve the target energy of the motor vehicle is calculated after the detected destination input. For example, the calculation of this amount of energy can be based on previous consumption data of the motor vehicle and / or using physical models. If the motor vehicle is a pure electric vehicle, this determined amount of energy is compared with the current battery charge of the motor vehicle. If the motor vehicle should be a motor vehicle with a pure combustion drive, the determined amount of energy is compared with a remaining tank filling of the motor vehicle. If the motor vehicle is a hybrid vehicle, the calculated amount of energy can be compared both with an existing battery charge and with an existing remaining tank charge.
  • the threshold value is fixed unalterably on the motor vehicle side.
  • the threshold value can be set manually, depending on the preferences of the driver. In the latter case, the driver can thus determine for himself which remaining range should still be present when he reaches the destination with his motor vehicle.
  • the vehicle is operated in a consumption optimization mode, in which the motor vehicle for the automatic implementation of measures operated to reduce the consumption of the motor vehicle until the achievement of the objective.

He is taken to the fear of lying down and he is not limited beyond what is necessary in his driving style. The driver can thus reach the destination as dynamically as possible even with a relatively low fuel tank level or with a relatively low battery level. It can be provided that the consumption optimization mode is activated only after confirmation by the driver.

On the basis of the provided driver profile can thus be determined whether it is a particularly restrained or possibly a particularly dynamic driver. Depending on the driver profile can then be assessed which of the measures to reduce fuel consumption of the motor vehicle depending on the driver type are perceived by this driver as disturbing or less disturbing.
  • the evaluation of the measures with regard to their influence on the limitations of the driver can be done individually and thus particularly well adapted to the respective driver.
  • the greater the influence of the respective measures on the achievable reduction in fuel consumption and the driver's impairment is assessed, the greater reduction in consumption and the greater restriction value assigned to the respective measures and in the activation and deactivation measures are taken into account.

  • the navigation device 14 is for detecting a destination input from a vehicle occupant.
  • the control device 16 is designed to determine which remaining range the motor vehicle 10 will have at its destination. The remaining range can be determined, for example, on the basis of previous consumption data, the route to the destination, on the basis of a stored driver profile and on the basis of a wide variety of physical models.
  • the control device 16 is designed to operate the motor vehicle 10 in a consumption optimization mode, in which the motor vehicle 10 is operated to automatically implement measures to reduce the consumption of the motor vehicle 10 until the target is reached, if the determined residual range is less than a predefined threshold value.
  • the motor vehicle 10 is thus operated in the said consumption optimization mode, if it is detected on the basis of the determined required amount of energy to achieve the goal that the required amount of energy with an existing battery charge and / or an existing tank filling the motor vehicle is only slightly or not reachable.
  • the driver is informed about this circumstance. He can now opt for activation of the consumption optimization mode.
  • the control device 16 is designed to continuously evaluate each of the measures for reducing consumption in terms of its influence on the resulting reduction in fuel consumption and to evaluate each of the measures continuously with regard to their influence on a restriction of the driver of the motor vehicle 10.
  • the controller 16 is also adapted to the individual measures depending on their respective to continuously activate and deactivate influences on the reduction in consumption and the driver's restriction until the destination has been reached, so that the motor vehicle 10 reaches the destination with a remaining range which corresponds at least to the threshold value and the restriction of the driver by the measures is minimized.
  • Fig. 2 the control device 16, the navigation device 14, a cruise control 20, an infotainment system 22, an air conditioner 24, a chassis 26 and an engine 28 of the motor vehicle 10 are shown schematically in a schematic representation.
  • a method for operating the motor vehicle 10 will be explained in more detail.
  • the required amount of energy for target achievement is calculated by means of the control device 16 on the basis of previous consumption data and physical models. This calculated amount of energy is compared for example with a remaining battery charge and / or a current tank filling the motor vehicle 10. If the destination is barely or not at all attainable, the driver is informed about this circumstance. He can now confirm that the consumption optimization mode is to be activated by means of the control device 16. A variety of measures a lowering of the energy consumption of the motor vehicle 10 is now brought about by means of the control device 16, so that the driver can reach his desired goal. In particular, different measures are taken by the control device 16, depending on whether the cruise control 20 is activated or not. The driver does not have to worry about the most economical way of driving to reach the destination. He is taken to the fear of lying down and he is not limited beyond the bare essentials in his driving style.
  • the consumption optimization mode When the consumption optimization mode is activated, numerous measures are taken to reduce the energy consumption of the motor vehicle 10. These include, for example: warnings regarding the driving style in order to achieve a reduction in fuel consumption; a reduction of the maximum retrievable power of the motor vehicle 10; a reduction of the maximum retrievable torque of the motor vehicle 10; a limit on the achievable maximum speed of the motor vehicle 10; a reduction of the power consumption of at least one electrical load of the motor vehicle 10, such as the air conditioning 24, the infotainment Systems 22, of displays or lighting devices for the interior lighting of the motor vehicle 10 or the headlights.
  • a deactivation of an all-wheel drive of the motor vehicle 10 take place.
  • navigation instructions for goal achievement can also be made along a determined consumption-optimized route.
  • the motor vehicle 10 is partially operated in a so-called sailing mode, in which a decoupling of the engine 28 of the motor vehicle 10 is carried out by a transmission of the motor vehicle 10. If the motor vehicle 10 should have an adjustable chassis, a lowering of the chassis of the motor vehicle 10 to reduce the air resistance of the motor vehicle 10 can be made. If the motor vehicle 10 has an active accelerator pedal, it can also be provided that a pressure point is set by means of the active accelerator pedal, which signals a not to be exceeded accelerator pedal position. In addition, it may also be provided to reduce a power consumption of an engine cooling system of the motor vehicle 10.
  • a predictive efficiency assistant of the motor vehicle 10 is activated, by means of which the driver is stopped for a particularly economical driving style via correspondingly displayed information, wherein the predictive efficiency assistant contains information about a route, speed limits and the like analyzed in a forward-looking manner along a route determined to reach the target.
  • the cruise control 20 may be a conventional cruise control which simply maintains a set speed of the motor vehicle 10.
  • the cruise control 20 may also be a so-called adaptive cruise control. If the cruise control 20 should not be activated, the driver is signaled by a pressure point of the active accelerator pedal - if the motor vehicle 10 has such a pedal - a recommended accelerator pedal position.
  • each measure is identified by an "x", which of the measures depends on whether the driver himself drives, whether it is in the cruise control 20 to a conventional cruise control or an adaptive cruise control, are activated.
  • the activation of the various measures to reduce fuel consumption of the motor vehicle 10 is staggered in several escalation stages.
  • the influence of the individual measures on the reduction in consumption of the motor vehicle 10 is calculated continuously dynamically and evaluated taking into account the effects on the driver.
  • each of the measures is continuously assessed for its impact on the resulting reduction in consumption. Moreover, each of the measures is also continuously evaluated for its influence on a driver's restriction of the motor vehicle 10. The individual measures will depend on their respective gen continuously activated influences on the reduction in consumption and on the limitation of the driver until reaching the destination so activated and deactivated that the motor vehicle 10 reaches the target with a remaining range, which corresponds to at least a predetermined threshold and the driver's limitation is minimized by the measures ,
  • the evaluation of the measures with regard to their influence on the achievable reduction in fuel consumption of the motor vehicle 10 and / or the limitation of the driver takes place depending on continuously provided ambient conditions of the motor vehicle 10.
  • the ambient conditions for example, the ambient temperature, the humidity, the ambient brightness, the Road surface, the curvature of the road, the gradient of the road or any speed limits along the route to reach the target.
  • the evaluation of the measures can be carried out with regard to their influence on the driver's restriction as a function of a driver profile provided which characterizes the driving behavior of the driver.
  • the different measures, the greater the influence of each measure on the resulting reduction in fuel consumption and the driver's restriction are each assigned an even greater reduction in consumption and an even greater restriction value and taken into account when activating and deactivating the measures.
  • the different measures are always activated and deactivated in such a way that on the one hand the destination can be reached with the current battery charge and / or the current tank filling of the motor vehicle 10, and on the other the driver in his usual Driving style is particularly limited by currently activated measures.
  • the driver of the motor vehicle 10 can thus reach the destination as dynamically as possible even with a relatively low fuel tank level and / or battery level when the consumption optimization mode is activated.
  • the consumption optimization mode is deactivated as soon as the motor vehicle 10 has reached the destination.
  • the previously activated measures for reducing fuel consumption therefore do not have to be manually deactivated again by the driver if he wants to continue driving with motor vehicle 10.
