1. A system for controlling a vehicle, the system comprising:
a deceleration actuator coupled to a first wheel of the vehicle; and
one or more electronic processors communicatively coupled to the deceleration actuator and configured to:
receive a vehicle park command;
responsive to receiving the vehicle park command, determine a maximum holding pressure threshold;
determine a requested braking pressure for the deceleration actuator;
determine whether the requested braking pressure exceeds the maximum holding pressure threshold;
responsive to determining that the requested braking pressure does not exceed the maximum holding pressure threshold, control the deceleration actuator to apply, to the first wheel during a hold time, a holding braking pressure equivalent to the requested braking pressure; and
responsive to determining that the requested braking pressure exceeds the maximum holding pressure threshold and prior to controlling the deceleration actuator to apply the holding braking pressure, perform a transition-to-hold test by
controlling the deceleration actuator to apply a hold test braking pressure equivalent to the maximum holding pressure threshold; and
detecting whether the vehicle is in a roll state.
