6.1.7. Management of dynamic stability

The hydraulic mechanism of management of DSC HU/CM system and strategy of management of system are in essence borrowed from the previous model 323, except for the following:

– the DSC block and the hydraulic block are incorporated for increase of convenience of service;

– the sensor of a lateral overload and the sensor of angular speed of roving are incorporated for maintainability improvement;

– the sensor of pressure of brake liquid is built in DSC HU/CM;

– conclusions of input-output of the DSC HU/CM block are changed;

– the electric amplifier of emergency braking is used for safety increase;

– the switch of DSC system is used for shutdown of work of DSC;

– the DSC HU/CM system gives out a signal of speed on the audioblock, the screen wiper and washer switch, to the automobile navigation block, the executive mechanism of system of maintenance of speed of movement and the alignment control unit on wires, and also deduces a signal of speed through CAN;

– CAN communication system is used.
