Abstract

The invention provides a fault detection method of an automatic driving controller. The method comprises the following steps: when a first peripheral set of an MCU module and a second peripheral set of a processor module work normally, whether the heartbeat of the MCU module and the heartbeat of the processor module are synchronous or not is judged; if not, a fault processor module is determined,and a first fault code corresponding to the fault processor module is reported; whether the fault processor module can be repaired by software or not is judged; when the software repair fails, the fault processor module is powered on again and initialized; when the fault cannot be repaired, the first fault code is reported to a cloud monitoring platform. Therefore, the fault of the automatic driving controller can be monitored and automatically repaired; when the fault exceeds the self-repairing capability of the automatic driving controller, the fault is fed back to the cloud monitoring platform, the problem analysis and fault repairing work is carried out by the cloud monitoring platform, so that the normal operation of the vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a fault detection method based on an automatic driving controller and the automatic driving controller. Background technique [0002] Autonomous driving technology has been a hot topic in recent years. Autonomous driving will bring disruptive changes in areas such as alleviating traffic congestion, improving road safety, and improving travel modes. The automatic driving controller is the brain of the automatic driving system. plays a key role. [0003] Currently, at least one classification system recognized by the global automotive industry is respectively proposed by the National Highway Traffic Safety Administration (NHTSA) and the Society of Automotive Engineers (SAE). Among them, both L4 and L5 levels of automatic driving technology can be called fully automatic driving technology. At this level, the car can already perform all driving operations without driver in...
