1. A system for a vehicle, the system comprising:
a parking brake control;
a sensor configured to measure a speed of the vehicle and output a measured vehicle speed;
a parking brake;
a primary hydraulic system including a primary controller and a primary hydraulic pressure generator; and
a secondary hydraulic system including a secondary controller and a secondary hydraulic pressure generator; wherein
the secondary controller is configured to
determine whether the vehicle is travelling at a non-zero speed while the parking brake control is actuated,
in response to determining that the vehicle is travelling at a non-zero speed while the parking brake control is actuated, determine whether hydraulic braking using the primary hydraulic system is available, and
in response to determining that hydraulic braking using the primary hydraulic system is not available, control the secondary hydraulic pressure generator to generate hydraulic braking pressure.
