Definitions
- the invention is based on a method for determining a movement parameter of a motor vehicle according to the preamble of the main claim.
- a vehicle device for evaluating received position signals from at least one transmitter is already known from DE 195 28 183 AI.
- time signals are received by the GPS satellite system, for example, and the position data for various movement parameters of the vehicle, for example the driving speed, acceleration, change in rotation and direction angles, are calculated therefrom.
- Devices for the vehicle or the engine are controlled with these movement parameters. For example, an ABS braking system or a vehicle speed limiter can be controlled from the determined speed signal.
- the inventive method and the device for determining a movement parameter of a motor vehicle with the characterizing features of the independent claims 1 and 6 has the advantage that the use of the differential position satellite system, preferably the D-GPS system, the instantaneous speed vector for the motor vehicle with its exact position in the global coordinate system can be determined very precisely.
- the determination of the differential position satellite system preferably the D-GPS system
- Position determination with a D-GPS system can be accurate to within a meter. This is a great improvement over the well-known GPS system (Global Position System), where tolerances of 100 m or more are possible.
- GPS system Global Position System
- a corresponding device for driving dynamics control (FDR) with early intervention for example by braking the corresponding wheel, can compensate for the yaw rate and thus effectively prevent the vehicle from swimming and getting out of control.
- FDR driving dynamics control
- the movement parameters determined by the D-GPS system can be used to control or even correct the data of the vehicle sensors. This takes place particularly in such phases, for example when Vehicle drives in normal travel on a straight line.
- the data from a yaw rate sensor can be determined, for example, during normal cornering.
- a warning message is output to the driver.
- the driver recognizes on the basis of the warning that, for example, the device for the
- Driving dynamics control is faulty. This gives him the opportunity to visit a workshop in good time to have his vehicle checked.
- Figure 1 shows a block diagram
- Figures 2 and 3 show diagrams in a global coordinate system
- Figure 4 shows a third diagram
- Figure 5 shows a table.
- the block diagram of FIG. 1 shows a controller 1, which is connected via a corresponding input to a navigation system 2, which is designed as a differential navigation system (D-GPS, Global Positioning System).
- the D-GPS system 2 supplies time-dependent data for the position determination of the motor vehicle in a global coordinate system x (t), y (t).
- a sensor 4 is connected to the controller 1, which detects the speed of the vehicle, for example, as a wheel speed sensor. Other sensors such as steering angle, Yaw rate, lateral acceleration and / or spring travel sensors can be provided.
- the controller 1 is connected to a control device 3, which is used, for example, for driving dynamics control (FDR, ESP).
- FDR driving dynamics control
- Control device 3 is connected to the sensor 4 and supplies its data to the controller 1, preferably in broken down form. This can be data about the vehicle speed v (t) or the steering angle w (t). On the other hand, the controller 1 provides processed data about the actual vehicle speed or the float angle b (t). The float angle is understood to be the angle that is formed between the vehicle longitudinal axis 1 and the speed vector V. This relationship is explained in more detail in FIG. 2.
- the diagram in FIG. 2 shows a global x, y coordinate system in which the movement of the vehicle 10 is described by three state variables. Accordingly, the position of the vehicle center of gravity S can be described by the vector a. The speed vector V attacks in the center of gravity S and points in the direction of movement of the vehicle. The third variable is the float angle b (t) between the vehicle longitudinal axis 1 and the speed vector V.
- the D-GPS receiver should preferably be located near the center of gravity S. In practice, this will not always be possible. A corresponding offset value for correction must therefore be taken into account when determining the position.
- FIG. 3 shows the measured variables which are used to determine the vehicle state variables, in particular the position of the Vehicle center of gravity S, which is determined from data of the D-GPS system 2, the rotation rate w of the motor vehicle 10, which is supplied by the sensor 4, for example a rotation rate or yaw rate sensor 5.
- this information can also be supplied by a corresponding control device 3 for driving dynamics control.
- the wheel speed or wheel speed is preferably supplied by a wheel speed sensor for alignment and support tasks.
- the rotation rate sensor 5 indicates the rotation rate w or the angle of rotation as a function of the driving speed or the distance traveled. Alternatively, the use of a corresponding steering angle sensor is also possible.
- Estimated vehicle speed in 1 direction This is formed from a reference speed, which the control device 3 supplies from the data from the wheel speed sensor and possibly further data, for example from engine management data.
- This parameter is treated like a measurand and explained in more detail below.
- the movement of the vehicle 10 from a point in time t 0 to a point in time ti is explained in more detail with reference to FIG.
- the x / y coordinate system shows the position of the center of gravity S 0 at time t 0 or Si at time ti with the corresponding speed vectors
- Equation 1 The float angle b can be determined using the relationship
- the float angle b can be calculated according to FIG. 4 as follows.
- the change in the float angle ⁇ b with time can be determined using the following relationship:
- Equation 5 The calculation in Equation 2 can be used to compare ⁇ in Equation 3 during uncritical driving conditions, since the signal of the rotation rate sensor is usually applied with an offset that has been added up by the integral in Equation 4.
- Equation 6 only take place when there is a critical driving condition, which is, however, only necessary in this case.
- the individual conditions for a critical driving state are predetermined by the sensor and tire tolerance comparison and are already taken into account in the control unit 3.
- Table 5 summarizes the relationship between the vehicle reference speed and the float angle in a critical and a normal driving condition.
- the D-GPS system 2 supplies the time-variable coordinates x (t) and y (t) in the global coordinate system to the controller 1.
- This receives the current rotation rate w (t) from the sensor 4, and the reference speed v (t).
- These values can also be supplied by a corresponding control unit 3.
- the controller 1 uses these values to calculate the current float angle b (t) and the new one Reference speed v * (t). These are available to the control unit 3 for further use. If the control unit 3 is designed as a vehicle dynamics control unit (FDR, ESP, these values can be used in particular to correct the current float angle b (t), ie to stabilize the current driving state of the motor vehicle 10.
- FDR vehicle dynamics control unit
- the data supplied by the navigation system are also used for the position determination in order to control the parameters supplied by the sensor 4 or by the control device 3.
- the travel path covered by the vehicle which was determined by the sensor 4 or the control device 3
- the driving speed as well as to the angle determinations from the values of the rotation rate sensor. If the difference determined from the satellite data and the sensor data exceeds a predetermined threshold value, this can be an indication of an error.
- a message is preferably output to the driver so that the driver can take his vehicle to a workshop for inspection.
