Vehicle crate for blade processors
View Patent ↗Methods, systems, and a computer readable medium are provided for a vehicle containing multiple blade processors for performing vehicle and/or infotainment tasks, functions, and operations. The blade processors can be included in a crate having a first communication zone defining a trusted network within the vehicle to connect with trusted computational devices and/or modules provided or certified by the vehicle manufacturer but not untrusted computational devices and/or modules provided by vehicle occupants, a second communication zone defining an untrusted network to connect with the untrusted computational devices and/or modules, and a third communication zone providing power and data transmission to the blade processors. A master blade processor can assign a component and/or module requiring a blade processor for execution to a selected blade processor.
1. A vehicle, comprising:
a plurality of blade processors, each blade processor performing a function that is at least one of a vehicle task, function, or operation and an infotainment task, function, or operation;
wherein:
the plurality of blade processors have a backplane;
the backplane has a first communication zone defining a trusted network within the vehicle to connect with trusted computational devices and/or modules provided or certified by the vehicle manufacturer but not untrusted computational devices and/or modules provided by vehicle occupants;
the backplane has a second communication zone defining an untrusted network to connect with the untrusted computational devices and/or modules; and
the backplane has a third communication zone providing power and data transmission to the plurality of blade processors.
2. The vehicle of claim 1 , wherein the first and second communication zones are connected logically on opposing sides of a firewall blade processor.
3. The vehicle of claim 1 , wherein a master blade processor enables a connection to a computational device connected to the first communication zone upon verification that the connected computational device is certified by a vehicle manufacturer.
4. The vehicle of claim 1 , wherein the first and second communication zones are configured as separate Ethernet switches and wherein the first and second communication zones are not in signal communication with one another.
5. The vehicle of claim 1 , wherein a firewall has a dedicated slot that bridges the first and second communication zones and uses the third communication zone for power connections.
6. The vehicle of claim 1 , wherein an output of each of the plurality of blade processors is an IP message framed into an Ethernet packet, wherein a sensor and/or controller of the vehicle communicates by a Car Area Network (“CAN”) protocol, and further comprising an Ethernet bus controller terminating a CAN bus to the sensor and/or controller and a CAN Ethernet controller subsystem to translate an Ethernet message from a blade processor to a CAN protocol-based message.
7. The vehicle of claim 1 , wherein the plurality of blade processors are configured as a crate having the backplane connector and on-backplane Ethernet interfaces enabling the blade processors to communicate with one another using Ethernet messages.
8. The vehicle of claim 1 , wherein the plurality of blade processors comprises a master blade processor operable to assign a component and/or module requiring a blade processor for execution to a selected blade processor.
