Problems solved by technology

[0004] However, when the offline detection method is used, it can only detect the reliability and product quality of the hardware and software of the domain controller product, but cannot detect the domain controller's own failure or network communication failure during the working process; In the hardware redundancy method, it is necessary to design different hardware structures for the domain controllers of different vehicles. Although the security and reliability of the domain controllers can be improved, the structural design is complicated and the cost is high, which increases the cost of the entire vehicle.

Embodiment 1

[0020] image 3 It is a schematic structural diagram of a vehicle control system provided by Embodiment 1 of the present invention. The vehicle control system includes: two domain controllers 101 in the same sub-network domain 10 and at least one vehicle load device 1011 .

[0021] Wherein, each domain controller 101 has a different actual Internet protocol IP address, but each domain controller 101 accesses the vehicle Ethernet general network through the vehicle Ethernet interface with the same virtual IP address.

[0022] Wherein, each domain controller 101 is respectively connected to the same vehicle load device 1011 through a CAN bus (ControllerArea Network, controller area network).

[0023] Each of the domain controllers 101 is respectively used to monitor the working status of the corresponding active domain controller in the sub-network domain after operating as a standby domain controller in the sub-network domain 10, when the working status When it is abnormal, se...

Embodiment 2

[0033] Figure 5 It is a schematic structural diagram of a vehicle control system provided by Embodiment 2 of the present invention. The technical solution of this embodiment is further refined on the basis of the above technical solution. The composition of the vehicle control system includes: two A domain controller 101, at least one vehicle load device 1011.

[0034] Wherein, each domain controller 101 has a different actual Internet protocol IP address, but each domain controller 101 accesses the vehicle Ethernet general network through the vehicle Ethernet interface with the same virtual IP address.

[0035] Wherein, each domain controller 101 is respectively connected to the same vehicle load device 1011 through CAN bus communication; each domain controller 101 is connected through CAN bus and / or Ethernet communication.

[0036] When the vehicle is powered on for the first time, each of the domain controllers 101 is also configured to send an inactive Address Resolution...

Embodiment 3

[0061] Figure 7 A structural schematic diagram of a vehicle provided in Embodiment 3 of the present invention, as Figure 7 As shown, the vehicle includes the vehicle control system in any embodiment of the present invention, specifically including: a controller 31, a memory 32, an input device 33 and an output device 34; the vehicle control system includes two domain controllers in the same subnetwork domain 311 and at least one vehicle load device 312; the number of controllers 31 in the vehicle can be one or more, Figure 7 Take two domain controllers 311 and two vehicle load devices 312 in the same subnet domain as an example; the domain controller 311, vehicle load device 312, memory 32, input device 33 and output device 34 in the equipment can be connected through the bus or otherwise connected, Figure 7 Take connection via bus as an example.

[0062] The memory 32 is a computer-readable storage medium and can be used to store software programs, computer-executable ...

Abstract

The invention discloses a vehicle control system and a vehicle. The system comprises two domain controllers located in the same sub-domain, wherein each domain controller has a different actual internet protocol (IP) address, the respective domain controllers access a vehicle-mounted Ethernet through a vehicle-mounted Ethernet interface with the same virtual IP address, each domain controller is used for monitoring the working state of a corresponding main domain controller in the sub- domain after operating in the sub- domain as a standby domain controller, and sending an alarm prompt to replace the main domain controller to become a new main domain controller when the working state is abnormal. The problem that the function of the whole vehicle is influenced by failure of the domain controller in the sub-domain is solved, meanwhile, domain controller redundancy is only adopted in the vehicle key domain, the hardware structure of the domain controller does not need to be redesigned, the safety and reliability of the whole vehicle are improved, and meanwhile the cost of the whole vehicle is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle control, in particular to a vehicle control system and a vehicle. Background technique [0002] In recent years, with the development of automobiles in the direction of electrification, intelligence, networking and lightweight, the number of electronic control units (Electronic Control Unit, ECU) on automobiles has increased year by year, and the overall electronic and electrical architecture of automobiles has become more complex. The automotive domain controller (Domain Control Unit, DCU) is often used to centrally manage many chips and ECUs with different functions, forming key nodes in the automotive Ethernet backbone network architecture, and the maintenance of security and reliability of the automotive domain controller directly affect the safety of the vehicle. [0003] The traditional methods to ensure the functional safety and reliability of domain controllers a...
