An apparatus comprising communication logic and a memory. The communication logic may be configured to receive a data payload, validate the data payload, decode an instruction from the data payload, generate a bypass signal in response to the instruction and generate a remote signal in response to an arm signal. The memory may be configured to store configuration data and store status information. The bypass signal may be compatible with a safing block configured to provide one independent signal for an actuator. The communication logic may operate according to a pre-defined end-to-end communication standard. The configuration data may be configured to enable a selected profile for the pre-defined end-to-end communication standard. The safing block may be configured to pass through the bypass signal generated by the communication logic as the arm signal. The communication logic may receive the arm signal from the safing block.

Hardware for end-to-end communication protection in ASIC

An apparatus comprising an arm control path, a deploy control path and a communication module. The arm control path may be configured to trigger an arm signal. The deploy control path may be configured to trigger a deploy signal. The communication module may be configured to communicate a remote signal to/from an end device, generate a bypass signal in response to the remote signal and generate the remote signal in response to detecting the arm signal. An activation signal for an actuator may be generated in response to the arm signal and the deploy signal. The arm signal and the deploy signal may be generated independently. The communication module may enable the remote signal to activate the end device. The bypass signal may be compatible with the arm control path and ensure an independent and parallel path for the arm control path to generate the arm signal.

Built-in end-to-end communication protection in ASIC hardware

An electronic controller of a restraint control system for a vehicle comprises an electronic control unit including a first serial interface. The electronic controller also comprises a communications controller including a second serial interface and a plurality of PSI5 (Peripheral Sensor Interface 5) digital communications interfaces. Each of the first and second serial interfaces are Serial Peripheral Interfaces (SPI) in direct communications with one another, and the digital communications interfaces are each configured to communicate with a remote sensor. The communications controller is configured to transmit a voltage sync pulse to each of the remote sensors via the PSI5 digital communications interfaces in response to a synchronization command received from the electronic control unit via the serial interconnection. The voltage sync pulses on each of the PSI5 interfaces may be staggered and non-overlapping to reduce EMI production and to reduce the current load of the electronic controller.
