Problems solved by technology

[0008] For the second existing technical solution, when the controller fails, the preset safety operation performed by another controller may not be able to fully cope with the complexity of the driving situation, which may lead to driving risks
At the same time, the two controllers are still transmitted to the actuator through a unified network, and there is also a problem that the signal transmission between the controller and the actuator may fail due to the high load of the backbone network
[0009] These disadvantages may increase costs and network load, and even further affect the safety of vehicles

Embodiment Construction

[0022] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0023] Such as figure 1 A kind of automobile driving redundancy control system shown, the present embodiment is illustrated with the intelligent driving controller (ADCU) as the control core, and it includes vehicle sensor 1, controller 2, redundant controller 3, controlled system 4, actuator 5, backbone network 6 and redundant network 7,

[0024] Wherein, the vehicle sensor 1 includes radar, camera, vehicle speed sensor, angular velocity sensor, heading angle sensor and other sensors used to identify the surrounding environment and the driving state of the vehicle;

[0025] The controller 2 is the control unit that controls the intelligent driving behavior of the vehicle, that is, the ADCU itself, which is the ECU used to receive sensor information and determine the follow-up operations that the vehicle should perform through calculation;

Abstract

The invention discloses a vehicle driving redundancy control system which comprises a vehicle sensor, a controller, a redundancy controller, a controlled system, an actuator, a trunk network and a redundant network; the controller comprises a control module and a state monitoring module; the control module is used for receiving sensing signals of the vehicle sensor uninterruptedly, generating a corresponding vehicle control instruction according to the sensing signals and sending the vehicle control instruction to the controlled system through a trunk network; the controlled system operates the actuator to execute a corresponding vehicle control action according to the vehicle control instruction; and the state monitoring module is used for detecting whether the control module has a fault.According to the invention, the integrity and the communication reliability of the control system can be guaranteed more effectively while the cost of the controller is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control systems, in particular to an automobile driving redundancy control system and a method thereof. Background technique [0002] The vehicle driving control system plays a decisive role in ensuring the safety and reliability of the vehicle, especially the key control systems including the intelligent driving system. When these systems ensure their normal operation, their redundant control must be considered to ensure that they are in a single In the event of a control system failure, the redundant control system takes effect to ensure the safety of the vehicle and passengers. [0003] For the redundant control of automobile driving system, the existing methods mainly have the following two design forms: [0004] The first redundant control scheme is to use two identical control systems to control the vehicle. figure 1 As shown, the two controllers are identical, with different...
