车辆制动控制方法、车辆制动控制装置及存储介质
By acquiring road condition and pedestrian distribution information, the system controls vehicles to decelerate in advance and adjusts deceleration strategies according to risk zones. This solves the problem of insufficient braking distance for autonomous vehicles when pedestrians suddenly appear on complex roads, thus achieving safe braking and improved passenger experience.

AI Technical Summary
Technical Problem
When existing self-driving cars encounter pedestrians suddenly appearing on complex roads, their braking distance is insufficient, leading to a high probability of traffic accidents.
Method used
By acquiring road condition information, predicting driving trajectories and pedestrian distribution information, and determining when the road condition information meets the intervention conditions, the vehicle is controlled to decelerate to the first speed in advance. The vehicle deceleration strategy is determined based on pedestrian distribution points and risk zones, including a deceleration process with multiple accelerations.
Benefits of technology
It effectively shortens braking distance, reduces traffic accidents, and improves the passenger riding experience.
