Vehicle driving mode control method and system

Abstract

The present application provides a vehicle driving mode control method and system, the method is applied to the domain controller of the vehicle driving control system; the vehicle driving control system is mounted on the vehicle controlled by wire, and further includes: sensing devices respectively connected to the domain controller, A positioning module and an HMI interaction module; the perception device includes a forward sensor, a side sensor, and a rear sensor; the method includes: when the vehicle driving control system is in the automatic driving mode, receiving the user's assisted driving mode through the HMI interactive module is turned on When commanded, or when a failure of the rear sensor is detected, the automatic driving mode is switched to the assisted driving mode, and the assisted driving system corresponding to the assisted driving mode is used to realize longitudinal control of the drive-by-wire vehicle. The application can conveniently switch between the automatic driving mode and the assisted driving mode, so that the driver can have a better driving experience while ensuring driving safety and making the vehicle more intelligent.

Description

technical field [0001] The present application relates to the field of software technology, in particular to a method and system for controlling a vehicle driving mode. Background technique [0002] At present, autonomous driving technology is in the stage of development and exploration. Combined with various perception sensors and high-precision positioning modules, it detects and recognizes the vehicle operating environment and the behavior of traffic participants, and transmits the information to the main controller of automatic driving. The main controller combines sensors Identification information, high-precision maps, GPS signals, and inertial navigation positioning information are used for trajectory planning and vehicle behavior decision-making, so as to control the normal operation of the vehicle without driver intervention. [0003] However, the software and hardware technology of the autonomous driving system is not yet mature. In the early stage of realizing the...

AI Technical Summary

Problems solved by technology

[0003] However, the software and hardware technology of the autonomous driving system is not yet mature. In the early stage of the realization of the automatic driving function, for complex scenes and emergencies, the driver needs to intervene in the control of the vehicle to ensure driving safety.

The current self-driving vehicle will completely exit the automatic driving system after manual intervention, which will cause the driver to take over frequently, which will not only make the driving experience poor, but also reduce the intelligence of the vehicle.
