Hardware architecture for automatic driving and execution method thereof

Abstract

The invention discloses a hardware architecture for automatic driving, and relates to the technical field of automatic driving, the hardware architecture comprises a plurality of target function modules, each target function module is used for independently realizing a target function in an automatic driving control process, and the plurality of target function modules are connected with one another; generating an automatic driving control instruction; the control module is used for controlling the vehicle to execute the automatic driving control instruction; and the backup redundancy module is used for monitoring the running state of the target function module and replacing the target function module to realize the corresponding target function when any target function module fails. According to the invention, a single target function module is responsible for a clear function, security redundancy is facilitated, each target function module is physically isolated, the problem of resource competition for the central processing unit and the graphics processing unit is solved, device breakdown is not caused when any target function module breaks down, and the stability and security of the system are improved.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a hardware architecture for automatic driving and an execution method thereof. Background technique [0002] Existing automatic driving methods generally use industrial computers as the main computing platform. With the increase in computing power requirements and the increase in the number of sensors, expansion cards need to be continuously added to industrial computers to meet the requirements, and the corresponding power consumption will become very large. It is huge and is not conducive to maintenance. At the same time, the demand for hardware performance is relatively concentrated. When a single point of failure occurs, the overall stability of the system will be extremely low. For example, the performance of the graphics processor will be reduced due to excessive temperature. The sharp increase will cause the vehicle to delay the response to the incident a...

[0002] Existing automatic driving methods generally use industrial computers as the main computing platform. With the increase in computing power requirements and the increase in the number of sensors, it is necessary to continuously add expansion cards to industrial computers to meet the requirements, and the corresponding power consumption volume will become very large. Huge and not conducive to maintenance. At the same time, the demand for hardware performance is relatively concentrated. Single point failures will lead to extremely low overall system stability. The sharp increase will cause the vehicle to delay the response to the event and seriously threaten the security. Therefore, the system needs a high cost for hardware security redundancy design
