Publication number: 20250018912Abstract: Embodiments herein comprise monitoring factors related to braking of an autonomous vehicle. In response to determining, based upon data from one or more sensors, whether a failure state from a set of one or more failure states has occurred, a failure log is updated to record the occurrence of the detected failure state. In one or more embodiments, the failure states have associated severity levels, and the updated log and associated severities are used to determine a braking safety or failure metric for the vehicle. In one or more embodiments, if the vehicle has a metric corresponding to a rule that correlates the braking safety metric value to a set of one or more actions, the corresponding action(s) may then be implemented. For example, if the braking safety metric has a value corresponding to a rule that indicates the vehicle is unsafe, the vehicle is parked.Type: ApplicationFiled: July 10, 2023Publication date: January 16, 2025Applicant: Apollo Autonomous Driving USA LLCInventors: Baoping YUAN, Yaoming SHEN

Publication number: 20250010822Abstract: This disclosure provides systems and methods for deceleration control during emergency braking using control algorithm override. An embodiment of the present disclosure provides a computer-implemented method for deceleration by a controlling device of an autonomous driving vehicle (ADV). The method includes engaging a braking system of the ADV to decelerate the ADV using a first deceleration algorithm. When an onset of discrepancy between a velocity of the ADV and a corresponding wheel speed of the ADV is detected, a processing device, based on the discrepancy, overrides an output of the first deceleration algorithm using a second deceleration algorithm that prioritizes in reducing the discrepancy between the velocity of the ADV and the corresponding wheel speed of the ADV over a target rate of deceleration computed by the first deceleration algorithm.Type: ApplicationFiled: July 7, 2023Publication date: January 9, 2025Inventors: Baoping Yuan, Yaoming Shen

Publication number: 20240383459Abstract: Operating a vehicle with an open door creates risks. Embodiments herein consider both when a vehicle is in an autonomous driving (AD) mode and a manual mode. When in AD mode, if an occupant opens the doors while the vehicle is moving, the control system may lower the speed to stop and may park the vehicle (or not park it depending upon the control policy). If an occupant opens the doors when the vehicle is stationary, the control system may keep the vehicle from rolling and from brake system failures. When the vehicle is in a manual model and a door is opened when the vehicle is moving, a warning message may be triggered; whereas, if a door is opened when the vehicle is stationary, the control system may keep the vehicle from rolling and from brake system failures. Warning messages may be triggered for different stages/conditions.Type: ApplicationFiled: May 17, 2023Publication date: November 21, 2024Applicant: Apollo Autonomous Driving USA LLCInventors: Baoping YUAN, Yaoming SHEN

Patent number: 12134376Abstract: This disclosure provides systems and methods for electrical power conservation during braking for autonomous or assisted driving vehicles, such as when electrical currents are continuously supplied to the brake system when the vehicle is temporarily halted at a slope. Braking hysteresis is the relationship between the input (e.g., operating pressure, caused by an electrical motor to increase the fluid pressures in the brake system) and the output (e.g., braking pressure applied by the brake pads on the rotors), in which the change of the output is different during the increase of the input and during the decrease of the input. The present disclosure provides techniques for conserving electrical power consumption by using the brake hysteresis.Type: GrantFiled: September 21, 2022Date of Patent: November 5, 2024Assignee: BAIDU USA LLCInventors: Baoping Yuan, Yaoming Shen
