Advance Safety Electronics
Advanced Safety Electronics ASK is the passive safety system on the (E85) Z4.The system is based on the same technology as the Intelligent Safety and Integration System (ISIS) of the E65/E66.
The ASE system consists of the Safety Information Module SIM and several control units, called satellites, that are linked across the byte flight bus. In the case of the MRS system there was only one central control unit. On the (E85) Z4, the acceleration sensors are integrated into the satellites.
The actuators are directly connected to the satellites and are activated by the satellites. The satellites are fitted at strategic points in the car. The distributed sensor system in the car enables measurement of the accelerations occurring as close as possible to the outer shell of the body and at the location of the collision.
The direct recording and processing of the information in the control unit mean that significantly shorter reaction times can be achieved. The mechanical time lag within the body to a central control unit is eliminated.
The distributed sensors in the satellites provide redundant information that is interchanged via the byte flight. This leads to even more reliable trigger decisions. In comparison to the MRS systems used to date, the ASK enables, (for example in the event of a side-on collision) earlier triggering.
