Embodiment Construction

[0086] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0087] The smart car multi-objective driving decision-making system provided in this embodiment is installed on the vehicle to be controlled 10, the vehicle to be controlled 10 is an automatic or semi-automatic vehicle, and has all the features and functions of a non-automatic vehicle. For example: the steering system, braking system, navigation system, etc. required to complete the driving task. The automatic vehicle can drive automatically in all road environments by controlling the throttle, brake pedal, steering wheel and other actuators without the intervention of a human driver. The semi-automatic vehicle can drive automatically in some road environments, such as highways, by controlling actuators such as the throttle, brake pedal, and steering wheel, and requires human drivers to intervene in emergency situations. The smart car multi-objective...

Abstract

The invention discloses a multi-objective driving control method and system for smart vehicles. The method includes: S1, formulating the driving operation to be performed by the vehicle to be controlled; S2, collecting information; S3, generating a decision Map; S4, judging other road uses Whether the decision point corresponding to the user's position and speed is valid, if not, go to S6; otherwise, go to S5; S5, perform the intended driving operation; S6, when other road users maintain the current speed, judge whether the valid Decision point: If possible, enter S7; otherwise, enter S8; S7, among the available valid decision points, select the decision point with the highest decision profit, and perform the driving operation to be performed in S1 accordingly; S8, the vehicle to be controlled gives up Driving operation to be performed, stop and wait. The present invention can realize safe and efficient driving decisions for autonomous vehicles by comprehensively considering various factors in various traffic environments.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a multi-objective driving control method and a decision-making system for an intelligent vehicle. Background technique [0002] Autonomous driving and unmanned driving technologies have developed rapidly in recent years. As a technology carrier, the driving decision of smart vehicles not only directly determines the riding experience of the passengers in the vehicle to be controlled, but also has a direct impact on other traffic participants in the road traffic environment. Impact. Therefore, improving the rationality of autonomous driving decision-making behavior is of great significance for the development of autonomous driving technology. [0003] The development of autonomous driving technology is a gradual process. In the short to medium term, autonomous vehicles will share the same traffic environment with vehicles driven by human drivers. However, current self-...
