Definitions
- the invention relates to a method for controlling a motor vehicle during and immediately after a flight phase according to the preamble of claim 1.
- Such a phase of flight is due to the uneven center of gravity distribution in the vehicle by a Abnicken, ie a rotation about the transverse axis of the vehicle, characterized as usually located there, heavy engine pulls the front of the vehicle due to the influence of gravity in the direction of the road.
- a phase of flight differs from a so-called rollover situation in that the rollovers associated with the term "rollover” are primarily rotational movements of the vehicle about the longitudinal axis, ie the roll rate and its summation to an absolute roll angle and the achievement of a static roll or dynamic tilt angle goes.
- the object of the present invention is therefore to present suitable measures for controlling a motor vehicle during and immediately after a flight phase.
- An essential idea of the invention is that the environment detected in the direction of travel, so for example to recognize the course of the lane and any obstacles or oncoming traffic, and taking into account vehicle dynamics variables, at least the vehicle's own speed, evaluated and automatically depending on it in the brake control is intervened.
- the brake control can be provided that the ESC system adapted, so for example its sensitivity is changed. It can brake preparation measures, such as the construction of the brake pressure (pre-brake) are initiated or even an automatic brake intervention.
- These interventions in the brake control are alternative measures and intervene differently in the driving behavior. Of course, these can also be used together in combination.
- a flight phase is detected.
- the environmental detection sensor system detects the surroundings in the direction of travel and, taking into account vehicle-dynamic variables, at least the vehicle's own speed, assesses and automatically intervenes in the brake control as a function of this.
- the strength of the brake control intervention as a function of the detection reliability of a hazard immediately after a flight phase varies, in particular with increasing recognition reliability, the strength of the brake control intervention is increased.
- the brake control intervention is preferably terminated if the driver actuates the accelerator pedal, that is to say the gas pedal or the like.
- the vehicle checks whether the vehicle can follow the course of the road after the flight phase. In such a case, the strength of the brake control intervention should not reach the full strength of emergency braking.
- the braking control intervention is also limited in a landing on or immediate agreement on the opposite lane, so that the vehicle can still be moved away from the opposite lane, preferably the time is reduced on the opposite lane.
- the strength of the brake control intervention is also varied in dependence on at least one of the following driving dynamics variables:
- the environmental sensor detects the vertical inclination angle of the road in the direction of travel or the distance to the road or preferably both sizes. From this, taking into account the intrinsic speed of the vehicle, the severity and the risk potential of the situation are derived and, depending on this, ie, for example, correspondingly strong, automatically intervened in the brake control.
- a motor vehicle has for this purpose a control unit, which is connected to at least one environment detection sensor.
- the control unit has an evaluation algorithm for carrying out the method, wherein the sensor detects the surroundings in the direction of travel and the control unit evaluates the surroundings in consideration of the intrinsic speed of the vehicle and automatically intervenes in the brake control as a function of this, i. give appropriate signals to the brake control or the algorithm is integrated into the brake control unit and converts there.
- the standard system for reducing kinetic energy is the brake system.
- this can be combined with an Electronic Stability Control (ESC) function, which is independent of the driver capable of generating braking forces.
- ESC Electronic Stability Control
- This can be used to advantage in the present situation to withdraw kinetic energy from the vehicle.
- Prerequisite is an unambiguous recognition of the dangerous situation and the consideration of the advantages and disadvantages of a driver-independent braking of the vehicle.
- the amount of engagement for the "false positive" case can be dosed by the amount of brake intervention.
- the thresholds for the activation criteria of the ESC system are lowered. This can be done sooner than in the default setting, where a compromise between sensitivity and robustness must be found.
