Definitions
- the invention is based on a method for determining a vector vehicle speed according to the type of the independent patent claim.
- the inventive method for determining a vector vehicle speed with the features of the independent claim has the advantage that the inertial sensors are supplemented by a locating device, so that a second value for the vector speed of the vehicle is thus determined by comparing the value that was determined by means of the inertial sensors and the value, which was determined by means of the locating device, to form an average value which represents a better estimate for the vectorial vehicle speed.
- This also means that there is no need for targeted braking to determine the vehicle speed, so that such control interventions are no longer necessary. This then leads to an overall reduction in the braking distance.
- Another advantage is that the vehicle dynamics control can be improved by means of ESP by means of the improved vector vehicle speed.
- the location device is a GPS (Global Positioning System), which enables a very precise location determination and thus also a very precise speed determination.
- the speed can be determined using the Doppler effect of the carrier signals or from the carrier phases. This then results in a speed vector, because both the amount and the direction as components of the Velocity vectors can thus be determined. This can be improved by using two or three antennas, so that the orientation in the surface or in space can be determined.
- a vehicle dynamics control such as the ESP is improved since a maximum number of sensor information is made available to the vehicle dynamics control.
- the weighting of the speed values which were determined by means of the locating device and the inertial sensors, depends on how many satellites the locating device can receive as a satellite-based system at the time of measurement, how many antennas are used and which speed is determined by the inertial sensors Slip the tires. Averaging the vector vehicle speed as accurately as possible is then possible by averaging.
- a device for carrying out the method according to the invention which has a sensor platform with a location device, wherein either two or three antennas are used when using a GPS system.
- FIG. 1 shows a block diagram of the method according to the invention
- FIG. 2 shows a block diagram of a vehicle bus system
- FIG. 3 shows a block diagram of a kinematic sensor platform with a locating device. description
- ABS anti-lock braking system
- TCS traction control system
- ASR anti-slip control
- ESP used.
- the sensors that such systems access are essentially yaw rate sensors, lateral acceleration sensors, wheel speed, brake pressure and steering angle sensors. These sensors are used to determine the driver's wishes with regard to the direction and the acceleration / braking, and on the other hand to determine the state of motion of the vehicle on this basis.
- the vehicle speed, the yaw rate and the float angle of the vehicle are very important parameters for correct control of the vehicle condition.
- Control devices can now have an intelligent sensor platform, such a sensor platform being an integration of inertial sensors, that is to say linear acceleration and rotation rate sensors.
- the aim is now to estimate the driving condition based on the model.
- such an intelligent sensor platform is now supplemented by a locating device which is designed in such a way that an improved estimate of the vector vehicle speed is possible. This improves the effect of a vehicle dynamics control such as ESP.
- FIG. 2 shows a block diagram of how different systems in a vehicle are connected to one another via a bus.
- a vehicle bus 19 for example a CA bus, connects a control unit that, among other things, consists of a Bus controller 18, a processor 17 and a sensor platform 16, with one
- Headlight range control 28 and an ESP system 30 each have a bus controller 27 and 29 in order to enable communication via the bus 19.
- the sensor platform 16 is connected via a data input to the processor 17, which processes the sensor data and corresponding data such as one
- Vehicle speed estimation is then transmitted by means of the bus controller 18 to the headlight range control 28 or the driving dynamics control 30.
- FIG. 3 shows the structure of the sensor platform 16 which is connected to the processor 17.
- the first GPS receiver has an antenna 20 and a receiving device 21, which are connected to a first data input of the processor 17.
- a group of inertial sensors 26 with downstream measurement amplification and digitization is connected to a fourth data input of the processor 17.
- the GPS receivers 21, 23 and 24 are connected by lines to synchronize them with each other.
- the antennas 20, 22 and 25 are connected to a receiving device which can evaluate the different signals together.
- the signals from the antennas 20, 22 and 25 are then interrogated successively by the single receiving device.
- the processor 17 determines a different value for the vector speed from the GPS data and the sensor data from the inertial sensors 26. By comparing these two values, an average or mean value is then formed in order to determine the best possible estimate for the vector vehicle speed. This value is then transmitted to the vehicle dynamics control 30.
- the float angle that is used for the headlight range control 28 can also be determined from the vector vehicle speed.
- FIG. 1 The block diagram shown in FIG. 1 describes the method according to the invention.
- ESP sensors sense, that is, the inertial sensors 26
- An ESP estimator 2 uses this to determine a first value for the speed 3 and a corresponding weighting for this speed value 4.
- the speed value 3 is determined from the accelerations that occur, that is to say primarily by integrating the determined acceleration values.
- the weighting 4 is determined from properties of the vehicle, such as the slip values of the tires.
- the speed value 3 is then multiplied by the weighting 4 in block 5.
- GPS sensors 6, as shown in FIG. 3, determine the exact location of the vehicle for each point in time. The vectorial velocity can thus be determined over time.
- the weighting values 4 and 8 are added together.
- the weighted speed values are added in block 12, and this added value is then divided in block 13 by the total of the weights from block 11 in order to determine an average value in block 14.
- This average value is then transmitted via the bus 19 to a driving dynamics control 15, here the ESP.
- the weighting 8 is transmitted to the driving dynamics control 15 as a further value.
- the weightings provide information about the quality of the measured variables. If, for example, the GPS provides very reliable information about the driving speed, the corresponding weighting is very high.
- a weighted mean value for the speed estimate with respect to magnitude and direction, that is to say vectorially, is then then available.
- the speed value 9 is now of a correspondingly good quality, that is to say of a high weight, which is determined by the driving dynamics controller 15, it is not necessary to actively brake a wheel by the ESP controller 15 in order to determine the driving speed.
- a major difficulty is that the vehicle speed is calculated in a fixed coordinate system using GPS.
- the speed variables are in a coordinate system that is fixed to the vehicle.
- the vehicle speeds in the lateral, transverse and vertical directions are referred to as VX, VY and VZ.
- a transformation between the two systems that is to say between the coordinate system fixed to the environment and the vehicle, can be carried out if the orientation of the vehicle in the environmental fixed system is known. If two GPS antennas are applied along the longitudinal axis of the vehicle, the position of the corresponding connecting line a in the plane can be determined.
- the vector a is determined in coordinates that are fixed in the environment. This line is rigidly connected to the vehicle and is therefore used as a reference line for coordinate transformation. This is done by forming the projection of the SD speed vector V onto the connection vector a, whereby the speed V x is obtained along the longitudinal axis of the vehicle:
- V y is in any case perpendicular to the vehicle's longitudinal axis. If two GPS antennas are used, the position of the vehicle about the vehicle's longitudinal axis, for example the roll angle, is missing. This missing information can be provided with three existing GPS antennas. In this case, the speed in V y and V z could also be calculated. With only two antennas along the longitudinal axis of the vehicle, an assumption must be made in order to be able to calculate V y . This consists in the fact that the road does not drop towards an edge, i.e. it has no inclination. Thus V y is perpendicular to the perpendicular. Consequently, V y is obtained by equating the z component of V across with zero.
