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.
