Fig. 1 is a block diagram of an electronic electrical system of a vehicle according to an embodiment of the present application. As shown in fig. 1 in combination with fig. 2, an electronic and electric system 100 of a vehicle according to an embodiment of the present application includes: an actuator module 110 and an ADAS System 120 (Advanced Driving assistance System).
The actuator module 110 is connected to a CAN (Controller Area Network) bus of the vehicle, and includes an actuator private CAN interface. ADAS system 120 includes an ADAS private CAN interface that is connected to the actuator private CAN interface via a private CAN bus, and ADAS system 120 sends the same and associated interface signals to actuator module 110 via the private CAN bus as actuator module 110 responds to the interface signals.
The actuator module 110 may, among other things, respond to ADAS system controller commands, such as performing braking, acceleration/deceleration, etc. functions based on signals sent by the ADAS system.
In a specific example, as shown in fig. 1 and 2, the actuator module includes, but is not limited to, an EMS module (Engine Management System) connected to a first CAN bus (private CAN1) of the vehicle and an ESP module (Electronic Stability Program) connected to a second CAN bus (private CAN2) of the vehicle, the first and second CAN buses communicating through a gateway. Of course, the architecture in which the first CAN bus and said second CAN bus communicate through the gateway is merely exemplary, and in other examples, it is not limited thereto, for example: or the execution systems are all on one CAN bus. Namely: the method is applicable to various architectures which can meet the connection relationship between an ADAS system and an execution system and an electronic and electric system of a vehicle provided with the embodiment of the invention, and the examples are not given here.
Referring again to fig. 1 and 2, the ADAS system includes, but is not limited to, a FRM module and a FCM module, wherein the FRM module (radar module) and the FCM module (camera module) are connected via another private CAN bus (private CAN).
It should be noted that, in the above description, the EMS module and the ESP module included in the actuator module are only exemplary.
In other examples, the EMS module may be replaced with a module that provides vehicle power or a module or assembly capable of providing similar vehicle power, etc., and the ESP module may be replaced with another module or assembly capable of providing similar ESP functionality.
In addition, the FRM module and the FCM module in the ADAS system may be integrated into a single module having both functions of the FRM module and the FCM module, and of course, the ADAS system may also include only the FRM module or only the FCM module.
The ADAS system 120 works as follows: the ADAS system 120 is configured to obtain and compare the interface variables of the actuator module 110 with the interface variables of the ADAS system 120 to determine the interface signals that are the same as and associated with the interface variables of the actuator module 110, and send the interface signals that are the same as and associated with the interface variables of the actuator module 110 to the actuator module 110 via the private CAN bus.
Among the interface signals that are identical and associated with the interface variables of the actuator module 110 are: interface signals identical to and associated with the interface variables of the FRM module and interface signals identical to and associated with the interface variables of the FCM module, the private CAN buses including a first private CAN bus and a second private CAN bus, wherein the FRM module is connected to the EMS module through the first private CAN bus to transmit the interface signals identical to and associated with the interface variables of the EMS module to the EMS module through the first private CAN bus, and the FCM module is connected to the ESP module through the second private CAN bus to transmit the interface signals identical to and associated with the interface variables of the ESP module to the ESP module through the second private CAN bus.
Specifically, the ADAS private CAN interface of the ADAS system 120 is mainly responsible for interaction with the outside, and as shown in fig. 3, the ADAS system 120 performs interface variable analysis, and analyzes the interface variables of the EMS module, the ADAS system 120, and the ESP module, respectively, as shown in a, B, and C in fig. 3, which represent different interface variables.
Then, interface face changing is classified, the same interface variables as the EMS module and the ESP module are listed respectively, and the interface variables which are directly related or indirectly related (i.e. associated) with the EMS module and the ESP module are analyzed. For example: according to the above analysis, the interface variables of ADAS are classified into 4 types:
part 1: relating to an EMS node;
part 2: consistent with the EMS interface;
part 3: relating to ESP nodes;
part 4: consistent with the ESP interface.
Finally, signals in Part 1 and Part 2 are transmitted through the private CAN 1; the signals in Part 3 and Part 4 are transmitted over the private CAN 2.
According to the electronic and electric system of the vehicle, the ADAS system CAN send the variables required by the actuator module to the actuator module through the private CAN bus, so that the actuator module CAN respond quickly, and the electronic and electric system has the advantages of small transmission delay of the variables and high transmission stability, and improves the safety and reliability of the vehicle.
