ABSTRACT:
A vehicle dynamic characteristic control apparatus for use with a motor vehicle having a controllable dynamic characteristic. The apparatus includes an actuator for controlling the dynamic characteristic of the motor vehicle, and a control unit for calculating a value for a setting of the actuator based on vehicle running conditions and converting the calculated value into a setting of the actuator. The control unit produces a start command when it receives an abnormal signal which does not occur during normal vehicle driving. An electric signal is produced to operate the actuator in a self-checking mode in the presence of the start command. The self-checking operation is terminated when a time has elapsed after the start command is produced. This is effective to avoid troubles which will occur if the self-checking operation continues for a long time.
