Description

The invention relates to the field of automobiles. More precisely, the invention relates to a method for displaying a reading of a system of an autonomous motor vehicle by a monitoring system of the motor vehicle and a corresponding monitoring system.

Tracking the real-time performance of an autonomous system in an autonomous vehicle is a key component of driving, either as part of the development process or during the operational phase. How this important information is summarized and presented to drivers plays an important role in the successful and safe operation of the autonomous vehicle.

US10467824B2 discloses a method for determining driving characteristics of a vehicle. In order to provide an improved method for determining a long-term mechanical stress that is exerted on components of a vehicle by a driving characteristic of the vehicle, it is proposed that during operation of the vehicle an acceleration of the vehicle be detected by an acceleration sensor in the vehicle and evaluated by a vehicle analysis system in the vehicle wherein a driving parameter occurring during an acceleration event in which the vehicle acceleration is above a predetermined threshold is used to determine a driving characteristic value of the vehicle.

However, while this prior art method improves various operational characteristics of a motor vehicle, such as e.g. g. acceleration, the system used according to this prior art does not involve different levels of criticality.

It is an object of the present invention to provide a method and a monitoring system by which a safer and more successful operation of an autonomous vehicle is achieved.

This object is achieved by a method and a corresponding monitoring system according to the independent claims. Advantageous forms of configuration are presented in the dependent claims.

One aspect of the invention relates to a method for displaying a reading of a module of an autonomous motor vehicle by a monitoring system of the motor vehicle, a current performance value of the module being determined by an electronic computing device of the monitoring system and the reading being determined as a function of the performance value and the reading being based on a Display device of the surveillance system is displayed.

According to one embodiment, a criticality level is determined depending on the performance value. The criticality level and the performance value are displayed on the display device as the reading.

Therefore, safer and more successful operation of an autonomous vehicle is achieved by displaying important performance data to drivers in an efficient manner.

In particular, an autonomous motor vehicle consists of several component functions, such as B. Sensor fusion, localization, planning, etc. The performance of each component function is evaluated and presented as feedback for the driver in real time. In addition to these key performance indicators, further evaluations are carried out that track the overall behavior of the autonomous system, such as B. how the vehicle drives and follows the rules of the road.

According to one embodiment, the readout of a module for driving dynamics and/or the readout of a module of component functions of the motor vehicle are displayed on a display device.

In another embodiment, the criticality level is displayed in different colors depending on the particular criticality level.

In another embodiment, a plurality of readings from a plurality of modules are displayed on the display device.

1 12 shows a schematic side view according to an embodiment of a motor vehicle 10 comprising a monitoring system 12 . The monitoring system 12 comprises at least one electronic computing device 14 and at least one display device 16. The monitoring system 12 is configured to display a reading 18 of a module S1, C1 of the motor vehicle 10, the motor vehicle 10 being an autonomous motor vehicle.

According to one embodiment, a method is performed for displaying the reading 18 of the module S1, C1 of the autonomous motor vehicle 10 by the monitoring device 12. A current performance value 20 of each corresponding module S1, C1 is determined by the electronic computing device 14 and a criticality level 22 becomes dependent determined by the power value 20. The criticality level 22 and the leis Value 20 are displayed on the display device 16 as the reading 18 of the module S1, C1.

According to one embodiment, the readout 18 of a module S1, C1 for driving dynamics S1 and/or the readout 18 of a system S1, C1 of component C1 of the motor vehicle 10 are displayed on the display device 16. Furthermore, the criticality level 22 is displayed in different colors depending on the specific criticality level 22, as in 1 shown by different shades.

According to one embodiment, a plurality of readings 18 from a plurality of modules S1 , C1 are displayed on the display device 16 . Furthermore, a name of the modules S1, C1 is also displayed on the display device 16.

Furthermore shows 1 that there are two sets of KPIs/modules. The first group, identified by S1, represents a summary of driving dynamics such as e.g. e.g., acceleration, distance, speed, lane keeping, etc. The second group, identified by C1, represents a component function evaluation, such as e.g. e.g., sensor fusion, localization, planning, etc. Each KPI displays information according to a criticality level 22 . The core of a module S1, C1 is a criticality level 22, which is displayed as a number and in a specific color. For example, a criticality level 0 is represented in green, a criticality level 1 is represented in yellow, a criticality level 22 is represented in orange, and a criticality level 3 is represented in red.

Next to the criticality level 22, a marker representing the name of the module S1, C1 is shown above, and a key performance indicator (KPI) is shown below, which tracks performance over elapsed time or performance over distance driven, depending on the key performance indicator. The performance indicator can be the performance value 20. The KPI of the vehicle dynamics module S1 are tracked over a distance driven, while the KPI of the component level C1 are tracked over elapsed time. The reason is that, for component metrics, the vehicle could be stationary while the system S1, C1 continues to run.

Furthermore shows 1 that there are two other performance indicators that track the overall behavior of either the individual components TC or how the vehicle drives TS. The display format is shown in 1 in the enlarged view of the display device 16. It contains the value of the KPI, which varies while the motor vehicle 10 is in a driving mode, meaning that the motor vehicle 10 can drive or stand still, and a short marker representing the name of the KPI . The components TC and TS can comprise a total power value 23 . The components TC and TS can consist of names and of the total power value 23 on the display device 16 .

The values of either the individual KPI or the overall KPI are in the range between 0 and 100. For example, a value of 100 means that everything so far has passed within constructed parameters, while a lower value means the presence of critical situations on the way .

To help drivers, additional messages giving an indication of what the problems might be may be displayed if the criticalities are present.

The criticality levels 22 are determined by threshold values. Some thresholds are fixed values, but most are dynamic. For example, a set of parameters stored in several files in a repository is provided for each evaluation. These parameters along with formulas implemented in the code determine the values of these thresholds that are generated on the fly. Most of them, for example more than 95%, are dynamic, which means that they change in real time depending on the state of a module S1, C1 and environmental conditions such as traffic, road network, vehicle speed and acceleration. Each criticality level is weighted differently. Time spent at a higher criticality level is weighted more heavily than time spent at a lower criticality level. For example, only if t=2 seconds is spent at criticality level 3 and t=2 seconds at criticality level 2 will time spent at criticality level 3 have a higher weight than time spent at criticality level 2.
