Abstract: This disclosure provides systems and methods for determining a rate of deceleration for automatic emergency braking (AEB) operations based, at least in part, on environment status including passenger status, road status, and the vehicle status itself, and providing a more comfortable passenger/occupancy feeling while maintaining autonomous drive safety as well when the AEB was engaged during Autonomous driving (AD). For example, based on a distance to an obstacle (or more obstacles, such as a vehicle behind) and a current velocity, a range of safe deceleration rates may be ascertained (e.g., to avoid impact against the vehicle in the front and allowing for spaces for the vehicle behind to decelerate). Within this range, a rate of deceleration is determined based on a status of the occupant of the vehicle, e.g., to avoid discomfort or even injury to the occupant.

Abstract: This disclosure provides systems and methods for providing a failsafe braking system to independently backup various braking controls, such as longitudinal control, stability control, and standstill control. For example, in addition to providing the longitudinal control, the stability control, and the standstill control in a primary braking system (PBS), a secondary braking system (SBS) may independently intervene a malfunctioning braking procedure (e.g., any one of the longitudinal control, the stability control, and the standstill control) of the PBS. The PBS malfunctions may be caused by power failure, actuation failure (e.g., failure of electric motor or otherwise loss of actuation pressure), or control failure (e.g., electronic control unit (ECU) or control circuitry failure). Thus, the SBS uses an independent set of power supply, actuation devices (e.g., motors, pumps, and/or valves), and provides a redundant control circuitry to back up the control circuitry of the PBS.
