摘要：
A method for implementing a transition from a functioning steering assistance system to a deactivated steering assistance system when a fault occurs, comprising the following steps: establishing the fault of the steering assistance system; establishing that all high-side power switches are functional (first case), or establishing that all low-side power switches are functional (second case); and in the first case: opening all high-side power switches and performing PWM-like control of the low-side power switches; or in the second case: opening all low-side power switches and performing PWM-like control of the high-side power switches.
