Problems solved by technology

[0007] However, when the network, hardware, and algorithm units of the computing platform itself fail, the vehicle will still be unable to complete abnormal processing procedures such as pulling over and parking. Therefore, it is necessary to carry out a safety redundancy design for the autonomous driving computing platform

Abstract

The invention discloses a safe and redundant automatic driving computing platform and a control method thereof. The computing platform includes at least two performance processors MPU, which are used to control the operation of an extended computing unit, that is, a functional algorithm module; at least one microcontroller MCU, It is used to control the switching of the performance processor MPU; at least two Ethernet switches are used to realize the communication between the performance processor MPU. The performance processors MPU are mutually backup, and when the main performance processor MPU is abnormal, the redundant backup performance processor MPU controls the operation of the function algorithm module. The invention realizes the redundant function of the automatic driving computing platform (controller) through the design of the network, hardware and middleware software, and can realize the real-time redundant takeover when the network, hardware and algorithm unit of the computing platform itself fails, and give the vehicle Sufficient capability for exception handling.

Description

technical field [0001] The invention belongs to the technical field of automatic driving, and in particular relates to a safety redundant automatic driving computing platform and a control method thereof. Background technique [0002] Autonomous driving is a field that involves personal safety and requires sufficient safety guarantees. In terms of security, there are the following designs: [0003] (1) The redundancy of vehicle actuators, that is, the braking and steering control unit of the vehicle. In the event of a failure of a main system, there is a backup system that can complete the braking and steering operations; [0004] (2) A variety of sensors serve as backups for each other. When one or a type of sensor fails, the system can still perform effective environmental perception and decision-making; [0005] (3) Redundancy of the body bus, regardless of whether Ethernet or CAN bus is used, there is a backup link to deal with communication interruption; [0006] (4)...
