Automatic driving control method and system for vehicle

Abstract

The invention provides an automatic driving control method and system for a vehicle, and relates to the technical field of vehicles. The automatic driving control method comprises the steps that a master controller obtains first environment information and map information around the vehicle in real time and sends the first environment information and the map information to a slave controller; the slave controller obtains second environment information around the vehicle in real time; the slave controller judges whether the master controller breaks down or not; and if so, the slave controller plans a parking path according to the first environment information, the map information and the second environment information sent by the master controller for the last time, and controls the vehicle to be automatically parked according to the parking path. The automatic driving control method provided by the invention is high in parking safety and good in comfort.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an automatic driving control method and control system for vehicles. Background technique [0002] With the development of technology, the safety of autonomous driving technology is getting more and more attention. According to the level of automatic driving system, the L4 automatic driving system is defined as a system that does not require human takeover and can stop safely. In order to reach the L4 level, the current industry mainly adopts redundant design, that is, to increase the margin on the original system to ensure that the system can still take safety measures when it is in an unexpected situation (such as downtime, etc.), thereby improving the system's reliability. safety and reliability. In addition, according to different operating scenarios and system cost requirements, various redundancy schemes have been derived, but they are essentially a mixed mode of sensor ...

AI Technical Summary

Problems solved by technology

However, the software and hardware of this platform are complex, it is difficult to meet the requirements of vehicle regulations, the reliability is not easy to guarantee, and the cost is high

In order to improve the reliability of the platform, the same hardware backup is used in some technical solutions, but the cost of the entire system is relatively high, and the occurrence of similar failures cannot be avoided at the same time

In other technical solutions, a micro control unit (MCU) without perception capabilities is used as a backup controller, but because it cannot detect and predict obstacles ahead, it can only perform emergency braking, resulting in poor parking comfort
