Abstract
Stabilization method and system for performing dynamic chassis control in a vehicle. An electronic stability control (ESC) includes an ESC sensor set; at least one chassis actuator; and a dynamic controller operably connected to at the least one chassis actuator. The ESC sensor set generates one or more sensor fault signals. Then, the method employs a dynamic controller to evaluate the signals corresponding to the sensor fault at least after a first fast fault signal, or a second slow fault signal. If the first fast fault signal is detected, the dynamic controller generates a signal for at least one of partially or completely temporarily switching off the at least one chassis actuator, while maintaining ESC in an active state. Conversely, if the second slow fault signal is detected, the dynamic controller generates a signal for temporarily switching off the ESC.
