Embodiment Construction

[0044] The embodiment of the present invention provides an emergency collision avoidance control method for an intelligent driving vehicle. During the emergency collision avoidance control process of the intelligent driving vehicle, for the execution of the FCW, AEB and ESA functions, through the setting of multiple preconditions, the functions between the functional units are set. Work in cooperation with each other, and high-priority functional units are executed first. When high-priority functional units cannot avoid collisions, they will notify low-priority units to execute. While ensuring the orderly operation of the intelligent driving function, it saves algorithm computing resources. And the low-priority functional unit can also feed back the execution status to the high-priority functional unit, ensuring that there must be measures to mitigate or avoid the danger of vehicle driving. Accordingly, the embodiment of the present invention also provides an emergency collisio...

Abstract

The invention discloses an emergency collision avoidance control method and system for an intelligent driving vehicle, and relates to the field of intelligent driving control, and the method comprises the steps: carrying out the real-time calculation and judgment of the collision risk of the vehicle, and activating an FCW alarm function and a path planning request when the judgment result shows that the vehicle has a first-level collision risk; based on the collision risk of the vehicle and when the vehicle has a secondary collision risk, if a driver adopts an emergency braking active intervention action, activating an emergency braking auxiliary function of the AEB; if the driver takes the emergency steering active intervention action, activating an emergency steering auxiliary function of the ESA; and if the driver does not take the active intervention action for collision avoidance, judging whether the automatic emergency braking function of the AEB can avoid collision or not. According to the invention, the algorithm calculation resources can be saved while orderly operation of the intelligent driving function can be ensured.

Description

technical field [0001] The invention relates to the field of intelligent driving control, in particular to an emergency collision avoidance control method and system for an intelligent driving vehicle. Background technique [0002] With the development of intelligent driving technology, more and more auxiliary driving functions are applied to vehicles, such as longitudinal functions FCW (Forward Collision Warning, forward collision warning system), AEB (Autonomous Emergency Braking, automatic emergency braking system), etc., Lateral control functions ESA (Emergency Steering Assist, Emergency Steering Assist), LKA (Lane Keeping Assist, Lane Keeping Assist System), ELK (Emergency Lane Keeping, Emergency Lane Keeping System), etc. When the vehicle is running and there is a risk of collision between the self-vehicle and surrounding traffic participants (vehicles, pedestrians, etc.), if the driver fails to respond in time, each function of the intelligent driving system will sepa...
