Definitions
- the invention relates to a method and a device for recognizing a rollover situation in a motor vehicle.
- Motor vehicles are being equipped with more and more passive restraint systems, such as belt tensioners, curtain side airbags, curtain airbags and front airbags. It is important for the safety of the respective vehicle occupants to reliably recognize an accident situation that makes it necessary to use the respective restraint. It must also be ensured that false triggering of the restraint is largely avoided in order to avoid necessary repairs.
- passive restraint systems such as belt tensioners, curtain side airbags, curtain airbags and front airbags.
- a particularly dangerous accident situation for vehicle occupants is a rollover of the vehicle about its longitudinal axis.
- EP 0 327 853 B1 describes a method for activating a safety system which protects the occupants in a motor vehicle.
- a signal describing the forward displacement of the occupants of the vehicle is derived from a signal from an acceleration sensor by means of double integration.
- a route is predicted that the occupants will have traveled relative to the vehicle at a point in time in the future.
- This path is composed of the path already covered from the zero position up to the current point in time, the speed, the further acceleration and the first derivative of the acceleration after the time. These are each weighted using appropriate factors and integrated in time.
- a direction-dependent pre-storage is determined by appropriately taking into account measurement signals from accelerometers, which on the one hand the longitudinal acceleration acquisition and on the other hand to record the lateral acceleration.
- an appropriate restraint is then activated, for example an airbag is triggered.
- the object of the invention is to provide a method and a device for recognizing a rollover situation in a vehicle, which enables robust and reliable detection of the rollover situation.
- the invention is characterized by a method and a corresponding device for recognizing a rollover situation in a vehicle, in which a rotation rate about a longitudinal axis of the vehicle and an inclination of the vehicle in the lateral direction are determined as the state variables.
- suitable sensors are preferably arranged in the vehicle, depending on whose measurement signals the rate of rotation and the inclination can be determined.
- An overturning situation is recognized when the state variables in the state pool spanned by them exceed a tripping threshold characteristic. Reliable detection of a large number of different rollover situations is thus easily possible, even in deviation from typical test rollover situations.
- typical rollover situations are to be understood as predefined accident scenarios, such as, for example, the vehicle drifting sideways into soft soil or bumping against a curb at the side. In this way, robust and reliable detection of rollover situations can be easily guaranteed. A simple calibration is also possible.
- the tripping threshold characteristic curve runs linearly in the state area between a dynamic and a static roll point.
- the respective trigger threshold value is characteristic of the roll energy that is required in the respective point of the status area in order to cause the vehicle to roll over cause.
- the static roll point is the one at which the rollover is caused essentially by the potential energy of the vehicle.
- the dynamic roll point is the one at which the rollover of the vehicle is essentially caused by the kinetic energy of the vehicle. Due to the linear course between the static and the dynamic roll point of the characteristic of the tripping threshold characteristic, this is very simple and nevertheless represents very precisely the respective situations in which a rollover of the vehicle is to be expected.
- the inclination of the vehicle is predicted. This enables a particularly early detection of an impending rollover of the vehicle, which has the advantage that there may be sufficient time to appropriately activate appropriate restraint devices.
- the prediction of the inclination is dependent on a detected lateral or high acceleration of the vehicle. In this way a high quality of the prediction can be achieved.
- the rotation rate is predicted. This enables a particularly early detection of an impending rollover of the vehicle, which has the advantage that there may be sufficient time to appropriately activate appropriate restraint devices.
- the rotation rate is predicted as a function of a detected lateral and / or high acceleration of the vehicle.
- high acceleration is understood to mean an acceleration in the direction of the vertical axis of the vehicle.
- lateral acceleration means acceleration in the direction of the transverse axis of the vehicle. stood. In this way, a high quality of the prediction can easily be guaranteed.
- the one state variable is corrected in such a way that the trigger threshold value characteristic is exceeded. This can easily ensure that typical rollover situations reliably trigger the respective restraint device.
- a plausibility check is carried out as a function of the detected lateral and / or high acceleration of the vehicle as a further prerequisite that the rollover situation is finally recognized. In this way, the probability can easily be reduced that a rollover situation is detected incorrectly.
- the inclination is determined as a function of the rotation rate.
- this can be done simply by integrating the rotation rate.
- the determination of the state variables can be carried out with a small number of sensors, preferably only one sensor.
- FIG. 1 shows a vehicle with a device for detecting a rollover situation
- Figure 2 is a block diagram of the device for recognizing the rollover situation.
- a vehicle 1 which is in particular a motor vehicle, has a longitudinal axis x, a transverse axis y and a vertical axis z.
- a rotation rate ⁇ is an angular velocity of a rotation about the vehicle longitudinal axis x.
- a rotation rate sensor 3 which detects the rotation rate ⁇ , is preferably arranged in the vehicle.
- the rotation rate ⁇ can also be determined by means of suitable other measured variables.
- a first acceleration sensor 5 is provided, which detects a lateral acceleration g y .
- a second acceleration sensor 7 is provided, which detects a high acceleration g z .
- a control device 9 is arranged in the vehicle, which is designed to detect a rollover situation of the vehicle 1 as a function of the measurement signals from the sensors and which is also designed to correspondingly control one or more actuators 11 to activate one or more passive restraint devices, such as, for example, one or more several belt tensioners, one or more curtain side airbags, curtain airbags or other airbags.
- the control device 9 is explained in more detail below with reference to the block diagram of FIG. 2 with a view to recognizing the rollover situation.
- the rotation rate ⁇ , the lateral acceleration g y and the high acceleration g z are supplied to a block B1 as input variables.
- the block B1 comprises a program which is stored in the control device and which is loaded and processed during the operation of the vehicle.
- the program is started in a step S1, in which variables are initialized if necessary.
- the rotation rate ⁇ is determined in a step S2. This is preferably done by means of a corresponding sampling of the measurement signal of the rotation rate sensor 3.
- a step S4 an inclination ⁇ of the vehicle 1 in the lateral direction is then determined. If no separate sensor is provided for this, this can be done simply with sufficient accuracy by integrating the yaw rate ⁇ over time.
- a first and / or second and / or third correction factor ki, 2 , k 3 are determined in a step S6.
- the correction factors can be predefined, but they can also be dependent on the lateral acceleration g y and / or the high acceleration g z .
- the determination of the first to third correction factors ki, 2 , k 3 as a function of the lateral acceleration g y and / or the high acceleration g 2 is preferably carried out by means of a map which was determined beforehand by corresponding tests with the vehicle or by simulations. Alternatively, however, the assignment can also be made using a corresponding analytical function.
- a predicted rotation rate ⁇ pr ⁇ d is determined. This is preferably done according to the formula given in step S8, ⁇ denotes the time derivative of the rotation rate ⁇ .
- T1, T2, T3 denote terms for test top beat situations.
- Such test rollover situations are typical rollover situations that are specified for certain cases.
- a first ter Tl is characteristic of the vehicle 1 sliding sideways into soft soil. In this case, the high acceleration g z is initially zero and the lateral acceleration g y has an almost constant value and at the beginning the rotation rate ⁇ also has a low value.
- the first term T1 is assigned a characteristic value.
- An example of a second term is the side impact on a curb or similar obstacle. In this case, the yaw rate ⁇ is still almost zero, but if there is already a very strong lateral acceleration g y . In this case, the second term T2 is then set to a characteristic value.
- An example of a third term is a situation in which the vehicle 1 drives onto a ramp with one or then two wheels on one side of the vehicle, as can be the case, for example, with a guardrail on a road.
- the vehicle 1 first experiences a strong acceleration in the direction of its vertical axis, that is to say a high acceleration g z, and the rotation rate ⁇ increases only after that. If corresponding values of the rotation rate ⁇ and the high acceleration g z are available, the third term is then assigned a corresponding characteristic value.
- T1-T3 has a characteristic value
- a predeterminable high additional value is added to the actual predicted rotation rate ⁇ p ed when determining the predicted rotation rate ⁇ pred .
- the terms T1-T3 are taken into account accordingly or not.
- the terms T1-T3 are preferably taken into account in step S8 when determining the predicted rotation rate ⁇ p red .
- a predicted inclination ⁇ pre d is determined in a step SlO. This is preferably done using the formula given in step S10.
- the inclination can be taken into account by taking the product of the third correction factor ⁇ k 3 and the time derivative ⁇ of the rotation rate ⁇ into account
- this product can also be dispensed with.
- steps S6 to S10 can also be omitted or one or more of steps S6 to S10 can be omitted.
- a block B2 has the predicted rotation rate ⁇ P red and the inclination ⁇ as input variables.
- the predicted yaw rate ⁇ pre d and the inclination ⁇ form state variables and span a state surface.
- a tripping threshold characteristic curve THD runs linearly between a static and a dynamic roll point ST, D. Starting from the static roll point ST towards further increasing inclinations ⁇ , it has an almost constant, in particular a constant, curve with respect to the predicted rotation rate ⁇ pre , Starting from the dynamic roll point D, it has an almost constant, in particular constant, course towards increasing values of the predicted rotation rate ⁇ pred with regard to the inclination ⁇ .
- a first rollover bay Ul is set when the state variables exceed the tripping threshold characteristic curve THD.
- a first quadrant of the state flat is shown in block B2.
- a block B4 is also provided, the input variables of which are the high acceleration g z and the lateral acceleration g y .
- a plausibility check for a detection of a rollover situation is determined and, if the plausibility check indicates a plausible rollover situation, a second rollover flag U2 at the exit of the Blocks B4 set.
- a block B5 is an AND gate at the output of which a third rollover flag U3 is set if both the first and the second rollover flags U1, U2 are set.
- the inputs of block B5 can have holding elements with an adjustable holding time, which retain the setting of the first or second rollover flags for the adjustable holding time as input values of the AND element.
- a block B7 is also preferably provided, the input variables of which are the yaw rate ⁇ and the predicted inclination ⁇ pre .
- Block B7 is designed in accordance with block B2, • only the input variables being changed accordingly. Accordingly, block B7 is designed to set a fourth rollover flag U4 when its state variables exceed the triggering threshold characteristic curve THD.
- a block B8 is also provided, in which the rollover situation is checked for plausibility in accordance with block B4 and a fifth rollover flag U5 is set as a function thereof if the rollover situation is plausible.
- a block B9 is an AND gate at the output of which a sixth rollover flag U6 is set if both the fourth and the fifth rollover flags U4 and U5 are set on the input side. Corresponding holding members can also be provided here on the input side.
- a block B1 is an OR gate at the output of which a seventh rollover flag U7 is set if at least one of the third or sixth rollover flags U3, U6 is set.
- a block B12 represents a possibly redundant control device, which is provided for security purposes and which sets an eighth rollover flag U8 if it also detects the rollover situation.
- the redundant control device is preferably constructed in exactly the same way as the system shown in the block diagram in FIG. If both the seventh and the eighth rollover flags U7, U8 are present at block B14, an actuating signal is generated FNF generated for the actuator 11, which then leads, for example, to the ignition of a curtain airbag.
- the control device 9 can also comprise only one of the paths that are given by blocks B2, B4, B5 or blocks B7, B8, B9.
