In an embodiment, a brake control system determines a brake pedal travel value and a brake actuation position based on a brake pedal travel sensor and a motor actuation sensor of an autonomous driving vehicle (ADV). The brake control system determines a first threshold value based on the brake actuation position. The brake control system determines a deviation of the observed brake pedal travel value from the brake actuation position or the raw brake pedal sensor value are above the first threshold value and detects an intention of an operator to apply a brake control in response to determining that the deviation is above the first threshold value. This way, brake intervention can be detected prior to steady state and detection of an operator intervention is robust and reliable.
