1. A system for automatically stopping an autonomous vehicle, the autonomous vehicle including a primary brake and a secondary brake controlled by one control module or different control modules, comprising:
an error detection module to detect an error in the control of the primary brake or the secondary brake by the one control module or different control modules; and
a supplemental control module, upon a detected error by the error detection module, to cause a stop of the autonomous vehicle using the primary brake or the secondary brake;
wherein the error detection module receives a corresponding error signal or a warning signal that is provided by a control unit of the vehicle, and wherein the error detection module is configured to access sensors that sense a failure resulting in a loss of control of the vehicle, and
wherein the supplemental control module is configured to stop the autonomous vehicle using at least one deceleration profile having three stages to increase safety by providing an appropriate alert to following vehicles, in which three constant deceleration periods are combined, in which in a first period, a lower deceleration is applied, in which in a second period, no deceleration is applied, and in which in a last period, a required deceleration level is applied to stop finally the vehicle in a predetermined time or distance.
