Definitions
- the invention relates to a method for distance control.
- the invention is based on the object, the driver or
- the method according to the invention is characterized in that a separate vehicle is held at a distance from a preceding vehicle by means of a drive torque predetermined by means of an accelerator pedal position adjusted by the driver.
- the advantages achieved by the invention are in particular that the driver of a vehicle with active driver assistance function remains involved in a longitudinal control of the vehicle and thus retains influence on the drive torque, in particular by means of the accelerator pedal.
- the accelerator pedal position which is controlled by the driver of the vehicle, by means of a sensor, for. B. potentiometer, and transmitted to adjust a belonging to the accelerator pedal drive torque to an actuator.
- This control unit controls the transmission ratio between a path of the accelerator pedal and a course of the drive torque. From the fact that in today's vehicles, the accelerator pedal position is usually determined by a sensor and transmitted to an actuator for controlling the drive torque, it follows that for the determination of the accelerator pedal position and the adjustment of the drive torque no additional arrangements are necessary to an assistance system for distance control to realize. Thus, a simple and inexpensive to design solution is given.
- Each accelerator pedal position leads to a single drive torque.
- several characteristic curves of the drive torque are predefined as a function of the accelerator pedal position, which are stored in the control unit. These characteristics are characterized by a different ratio between the accelerator pedal position and the associated drive torque. Only those belonging to a minimum and a maximum position of the accelerator pedal Drive torques, no drive torque and maximum drive torque are the same in all stored characteristic curves. Thus, for the driver of the vehicle, even with active assistance function, the entire band of the drive torque can be called up and the tendency, monotonically increasing behavior of the drive torque with stronger actuation of the accelerator pedal is maintained and controlled by the driver. Furthermore, it is possible based on the different characteristics to adapt the ratio between the accelerator pedal position and the drive torque to a variety of requirements.
- Which characteristic of the drive torque is specified as a function of the accelerator pedal position depends z. B. from which distance and / or which relative speed of the own to the preceding vehicle exist.
- the instantaneous distance and / or the relative speed are determined by sensors, for. As radar, ultrasonic sensors, infrared sensors, image recording units, recorded and transmitted to the actuator.
- the relative speed of the own vehicle to the preceding vehicle for example, from the change of the distance in a predetermined time interval, for. B. by computational processing, or directly determined by the Doppler effect.
- Today's vehicles are usually equipped with suitable arrangements for determining their own speed. Therefore, only the additional equipment of your own vehicle with sensors for distance and / or relative speed determination is necessary. Thereby and by the simple practicability of the calculation of the
- Relative speed creates an assistance system for distance control, which can be produced with low material and consequent low cost. Furthermore, the possibility of retrofitting of vehicles with the assistance system for distance control is given on the basis of this low cost.
- the required distance to the vehicle in front is determined depending on a traffic situation and / or legal and other regulations. As a result, a distance adapted to the traffic situation and the statutory provisions is reached to the vehicle in front and increased safety.
- the associated drive torque is reduced by means of the setting unit with constant accelerator pedal position. This leads to the advantage that the distance between one's own vehicle and the vehicle in front, in particular due to the constant accelerator pedal position, is increased almost unnoticed by the driver.
- the method for distance control is realized by means of the integration of the above-mentioned devices in a control loop.
- This control loop is characterized in that at least one sensor measures the distance of its own to the vehicle in front and this distance value is compared with a fixed distance value adapted to the vehicle situation. If the measured distance to a vehicle in front is less than the predetermined value, the drive torque corresponding to the instantaneous accelerator pedal position is reduced by means of the setting unit. Based on the consequent reduction in the speed of the own vehicle, the distance to the vehicle in front increases.
- the simple structure and the uncomplicated operating principle of the control loop lead to a low-interference and low-maintenance function of the assistance system for distance control.
- the distance behavior of the driver of the vehicle improves with the help of the assistance system for parking regulation and unintentional distance underruns, eg. B. due to long monotonous rides are avoided.
- the driver of the vehicle with active assistance function has the opportunity to Entire band of the drive torque, retrieve, in particular, the minimum and the maximum drive torque are always available at the same accelerator pedal positions.
- Fig. 1 shows schematically a diagram which includes the functional dependence of the drive torque of the accelerator pedal position.
- FIG. 1 shows by way of a diagram how a drive torque M associated with an accelerator pedal position G changes with a reduction in the distance A of a separate vehicle (not illustrated in more detail) to a preceding vehicle (not shown).
- a characteristic curve Kl shows a profile of the drive torque M as a function of the gas pedal position G, which is not influenced by the intervention of an assistance system for distance control.
- the unaffected characteristic KO is due to a linear course between an intersection of a minimum
- the output characteristic KO can also be any other desired course between the intersections of the minimum accelerator pedal position G m i n and the minimum
- Gas pedal position G max and a maximum drive torque M max have, however, is always formed monotonically increasing.
- Vehicle is determined by means of a sensor, not shown. This momentary distance is fixed with a predetermined distance value, which corresponds to the vehicle situation and legal and other provisions compared.
- a distance reduction A below this predetermined distance value to a distance Al the uninfluenced drive torque MKO is reduced at a constant accelerator pedal position G on a, to a stored in the actuator characteristic curve Kl associated, reduced drive torque MKl means of a not shown adjusting unit.
- the constant accelerator pedal position G the distance between the driver's vehicle and the vehicle in front of it increases almost unnoticed for the driver of the vehicle, if it does not counteract the intervention of the distance control by means of a stronger actuation of the accelerator pedal.
- the distance to the preceding vehicle can continue to decrease to a distance A2.
- the drive torque M is further reduced to a reduced drive torque MK2 by means of the actuator at a constant accelerator pedal position G, which belongs to a stored in the actuator K2 characteristic.
- the distance reduction A is counteracted.
- the drive torque M is further reduced by means of the setting unit.
- This reduction of the drive torque M takes place when the minimum distance A m i n to a certain vehicle situation is reached, to a reduced drive torque MK m i n associated with the characteristic curve K m i n in order to counteract the reduction in distance A.
- the characteristic K m i n represents the strongest intervention of the assistance system on the course of the drive torque M as a function of the accelerator pedal position G. Regardless of the strength of the intervention of the assistance system for distance control, all characteristic curves K0, K1, K2, K m i n stored in the setting unit are characterized by the same minimum drive torque M m i ⁇ at minimum
- the curves KO, Kl, K2, K m i n are given over the entire course as monotonically increasing.
- the increase of the drive torque M decreases with increasing distance reduction A at low accelerator pedal positions G, but increases with larger accelerator pedal positions G with increasing distance reduction A increasingly non-linear. That is, the driver of the
- Vehicle is even with active assistance system, the entire band of the drive torque M available, only a gear ratio between a path of the accelerator pedal and the drive torque is changed by the actuator.
- the distance behavior is improved almost imperceptibly, and the safety for the vehicle and its surroundings is increased, as long as the driver does not deliberately counteract the assistance system for parking regulation. 12
