Definitions
- the invention relates to a control system of a vehicle.
- Such a control system is known for example from DE-A-41 11 023 (US Pat. No. 5,351,776).
- a control of the entire vehicle, at least with regard to the drive train and brake, is proposed there, which has a hierarchical order structure for the control tasks.
- the control structure described there comprises coordination elements which convert a command originating from a higher hierarchy level into commands for elements of a subordinate hierarchy level.
- the contents of the commands passed from top to bottom in the hierarchy structure represent physical variables that determine the interfaces between the individual hierarchy levels.
- the interfaces described here are based on the physical conditions of the vehicle movement, in particular the drive train and the brake. A consideration of a vehicle control going beyond this, for example taking into account the body electronics and the vehicle electrical system control, is not described.
- a structure for a vehicle is known from the SAE paper 980200 "CARTRONIC - An Open Architecture for Networking the Control Systems of an Automobile" by Torsten Bertram, Rainer Bitzer, Rainer Mayer and Asmus Volkart.
- the individual elements of a Vehicle controls are assigned to various components at predetermined levels of detail, between which information is exchanged within the framework of predetermined communication relationships.
- a central coordinator and the components electrical system, vehicle movement, body and interior and drive are provided. These components are each in The drive component is divided into a coordinator, the engine, the clutch and the transmission, and the distribution and management of the resources available in the vehicle and the consumers consuming these resources is according to
- consumers share the common resource on the same level as consumers and the coordinator responsible for the resource.
- the drive resource which is a resource for both the vehicle movement component and the body and interior, is arranged on the first level.
- resource is understood to mean a service that is made available for consumption by components, so-called sources, other components, so-called sinks or consumers.
- resources are the resource "mechanical power", which is generated by the drive (motor,
- Software component is installed, which monitors the performance and the power consumption of the vehicle components.
- the strategy pursued is applied centrally there. If, for example, an excessive demand for power is determined at an operating point, vehicle-specific power limits for the individual consumers or consumer groups are determined in accordance with this applied strategy, depending on the operating point. Within this limit, the individual components will then initiate appropriate measures, such as switching off individual units, based on local criteria that the central component does not know. In other words, this means that the specific technical possibilities are applied locally, the central strategy is applied centrally, so that a non-retroactive exchange of software components is possible, for example in the event of a hardware change (use of other units, etc.).
- the software component is added up and converted into physical manipulated variables, such as torque or speed, taking into account the existing boundary conditions. This means that larger software components remain autonomously functional, which leads to leaner programs with reduced or distributed functional scope and facilitates distributed development and testing of the individual components.
- the consumer common resource eg motor-gear unit
- the coordinator responsible for the administration and distribution of this resource (“coordinator overall vehicle") knows not the resource (only via the drive / brake component). This will make it easier, more vertical
- the communication relationships in the first level of detail between the coordinator overall vehicle and the components arranged there can be reduced to request and query relationships, i.e. no measures for the formation of specific commands (orders) are to be provided in the coordinator.
- the structure described below is invariant to new or dropped consumers, since the coordinator does not necessarily have to level as the source and the consumer must be arranged.
- the resource management and distribution can be designed independently and thus offers the possibility of reusing software modules that have already been tested with standardized physical interfaces.
- FIG. 1 shows, using the example for the “vehicle movement” component, the described resource management and distribution in general form, while in FIG. 2 the communication between individual levels is shown using the example of the “vehicle movement” component.
- the solution described below is implemented in at least one computer element.
- the individual components can be divided up among various computing elements or just one computing element.
- the software shown In this sense, the goods structure is independent of the specific hardware implementation.
- FIG. 1 shows the structure according to the invention for the control of motor vehicle components, which comprises all tasks in the vehicle area, using the exemplary embodiment of controlling the vehicle movement.
- the structure takes into account the increased requirements for a motor vehicle control with regard to comfort, safety and consumption and the associated strong coupling of the individual components. It can be mapped to any hardware topology.
- the example shown in FIG. 1 represents the control of the components of the drive train, which is an essential source of the mechanical power for the entire vehicle that is consumed by various systems. Therefore, requirements regarding vehicle-wide management of this energy source arise when controlling the drive train.
- Figure 1 shows a software structure for resource management and distribution in a vehicle control.
- the components of a vehicle are represented within the associated control software by corresponding components, so-called software objects. Examples of such components are the controls and the control elements for the engine, the converter, the gearbox, the chassis, the steering, etc.
- components (objects) that perform control tasks eg coordination of the engine-gearbox unit) , Coordination of vehicle movement, coordination of the entire vehicle, etc.
- components (objects) that provide information of general interest e.g. sensors, estimators, etc.
- Several components of any type can be combined into more abstract components (e.g. vehicle component movement, body and interior, etc.). This modularization is based on the mechanical and electrical components, assemblies and functional units present in the vehicle.
- the component 10 for the control for the vehicle movement that for the elements of the body and interior (12) and a coordination component 14 (coordinator overall vehicle).
- the latter monitors, among other things, the provision of power and the power requirement of resources required throughout the vehicle, for example the mechanical output of the engine and the electrical output of the electrical system. All communications at the highest level of detail lead to further communications and / or the execution of actions in the individual components.
- This is shown in FIG. 1 on the basis of a detail of the “vehicle movement” component 10.
- the next level of detail of this component comprises control systems 101 for the drive and the brake, for the chassis 102 and for the steering 103.
- a coordinator is in this detail level 104 is provided for the vehicle movement, which, in accordance with the coordinator for the overall vehicle, manages the resources required for this level of detail, maintains communication with the coordinator for overall vehicle 14 and manages communication with components 101 to 103.
- the drive / brake component is shown using the example of the motor-gearbox unit.
- a coordinator 1011 and a control object 1012 for the motor, for the torque converter (1013) and for the gearbox (1014) Communica - Relationships between the control objects and the co- The ordinator or between the overall component and the coordinator vehicle movement 104 are shown.
- the component "body and interior" is detailed accordingly.
- the coordinator 14 which manages and distributes the mechanical power resource, is therefore not known. The resource and coordinator are therefore at different levels.
- Orders for example between objects 101 to 103 and coordinator 104, are specified as communication relationships between individual components, by means of which the order recipient specifies the setting of a certain power or some other physical quantity.
- query relationships are provided for obtaining information, via which the coordinator 14, for example, queries the power requirement for electrical power of the vehicle movement component.
- a third communication relationship is the request relationship, via which desired setpoints are transmitted, which should be set by the requested component. Due to the suitable arrangement of the components, order relationships can be dispensed with in the first level of detail (see also below).
- FIG. 2 the communication between the components of the top level of detail shown in FIG. 1 is described using an exemplary embodiment. It is the communication of the coordinator overall vehicle 14 with the components vehicle movement 10 and bodywork which are assigned in rie and interior 12.
- the resource "mechanical power" is managed, which is arranged in the drive component on a lower level of detail.
- the only source is assumed to be the engine or the drive train 101. Are further sources for the mechanical If there is power available, the communication is duplicated and the values added in the coordinator vehicle movement or overall vehicle.
- the coordinator of each type of resource is a sub-component of the coordinator for the entire vehicle and coordinates the distribution of services as follows.
- Each coordinator asks all components (10, 12) of the first level of detail about their current maximum contribution (Pmax) to the respective service provision (communication link 1). This query is forwarded to the drive 101 component in the vehicle movement detail level and is answered by it.
- Each component e.g. brake component in the vehicle movement detail level
- the coordinator of the overall vehicle asks each component of the first level of detail about their performance requirements
- PV_Soll, PNA_Soll (communication link 2).
- the corresponding power requirement value is made available by the respective collector and supplied to the coordinator of the overall vehicle.
- the result is a power requirement value supplied by each component (10, 12) to the coordinator overall vehicle 14.
- the coordinator checks whether the total power requirement, ie the sum of the power requirement values supplied by the components, exceeds the total power Pmax of the resource (communication relationship 3). In this case, it calculates from the operating state Priorities and a strategy specified in the specification for each component of its level of detail a maximum allowed consumption.
- the component coordinators request this restriction from the resource coordinator (communication relationship 4) and, if necessary, reduce the local requirements using their own strategy (eg switching off the air conditioning compressor).
- the coordinates of the components formulate the orders for the sources assigned to them in a physically unambiguous form, for example as the setpoint torque MV_Soll for the drive component (communication relationship 5).
- the additional requirement from other components MNA_Soll may be queried and taken into account (see communication relationship 5).
- the drive component then sets the requested torque so that the coordinator for the overall vehicle can distribute the resource according to the requirements of the components.
