Problems solved by technology

[0004] For self-driving pure electric buses, due to the combination of self-driving technology and new energy technology, it is easy to ignore the possible safety factors of new energy systems and components in the process of automatic driving control, and the depth of automatic driving systems and new energy control systems cannot be achieved. Interaction can only consider safety issues from a single perspective, without forming a whole, and safety cannot be considered comprehensively from the perspective of new energy vehicles. The present invention provides a safety-based control system and method for autonomous driving pure electric buses

Embodiment 1

[0042] Such as figure 1 As shown, the technical solution of the present invention provides a safety-based self-driving pure electric passenger car control system, including a driving brain and an EPS steering system, an EBS braking system, and a vehicle controller that are communicatively connected with the driving brain; the EBS braking system and Vehicle controller connection;

[0043] The vehicle controller is connected with new energy component systems and vehicle auxiliary components;

[0044] The driving brain is used for decision-making in the process of automatic driving; on the one hand, the driving brain communicates with the vehicle controller and the EBS braking system, and on the other hand controls the EPS steering system to realize the steering of the vehicle in the automatic driving mode;

[0045]The vehicle controller is used to execute on the basis of the comprehensive new energy component system and the status of the vehicle auxiliary components, and contro...

Embodiment 2

[0059] Such as figure 2 As shown, the technical solution of the present invention provides a safety-based self-driving pure electric bus control method, including the following steps:

[0060] (1) The driving brain sends an instruction to enter the automatic driving mode to the vehicle controller. At the same time, when the vehicle controller does not detect that the brakes are artificially stepped on, it enters the automatic driving mode; in this embodiment, when entering the automatic driving mode from the non-automatic driving mode , the driving brain sends an instruction to enter the automatic driving mode to the vehicle controller through CAN2, and at the same time, if the vehicle controller does not detect that the brakes are stepped on manually, it will enter the automatic driving mode. At this time, if the vehicle's high-voltage power is not ready, the driving brain will send a "high-voltage command" to the vehicle controller through CAN2. After receiving the command,...

Description

technical field [0001] The invention relates to the technical field of self-driving pure electric buses, in particular to a safety-based control system and method for self-driving pure electric buses. Background technique [0002] With the gradual development of autonomous driving technology and new energy technology, the number of application examples of the combination of autonomous driving and new energy is increasing. However, safety problems of autonomous vehicles occur from time to time, and safety hazards still exist. Therefore, while promoting autonomous driving technology, it is necessary to ensure safety from all aspects and improve vehicle safety. [0003] At present, various cities are accelerating the demonstration operation of self-driving pure electric buses and other vehicles. Since there are few application examples of the combination of automatic driving and new energy, new energy technologies have not been well integrated, and safety issues are often only ...
