Multi-working-condition self-adaptive early warning braking system

Abstract

The invention discloses a multi-working-condition self-adaptive early warning braking system which comprises an external signal receiving module, an emergency braking self-adaptive module, a man-machine interaction module and an ESC actuator. The external signal receiving module is used for receiving an external sensing signal; the emergency braking self-adaptive module comprises an environment analysis module, a self-adaptive analysis module and a decision control module, the environment analysis module classifies the traffic environment in front of the vehicle according to the external sensing signal to determine the current working condition, then the self-adaptive analysis module performs self-adaptive adjustment according to the working condition type to determine the current emergency braking condition, so that the pedestrian collision early warning and braking sensitivity under different conditions is different, and finally, the decision control module judges the current collision danger degree according to the self-adaptive adjustment result, sends early warning information corresponding to the collision danger degree to a human-computer interaction module, sends a controlsignal corresponding to the collision danger degree to an ESC executor, and controls the ESC executor to execute the early warning and braking according to the control signal. According to the invention, self-adaptive emergency brake adjustment can be realized.

Description

technical field [0001] The invention belongs to the field of automobile auxiliary driving, and more specifically relates to a multi-working condition self-adaptive early warning braking system. Background technique [0002] The L2-level intelligent driving assistance emergency braking system (Advanced Driving Assistance System, ADAS) helps the driver actively provide deceleration braking force in the event of a collision risk. Currently, the active emergency braking system mainly performs pre-collision prediction for dangerous vehicles and pedestrians. New Chinese cars The evaluation specification (China-New Car Assessment Program, C-NCAP) requires vehicles to have the ability to avoid collisions or mitigate collisions with near-end and far-end crossing pedestrians. Due to poor accuracy and other reasons, the actual braking effect of the emergency braking system is not ideal for the scene of pedestrians crossing, and pedestrian collisions cannot be completely avoided.
