Automotive Smart Grid
A control platform that combines all the car components into a single real-time control system. ASG consists of ECU modules, power-line communication wiring and a distributed synchronous computing network to make up the full EE Architecture of a vehicle
10x reduction in wiring of a passenger car
Synchronous system provides real-time decision making
Significantly greater performance and computing power than central computers in modern cars
A Single Quantum Computation in all ASG Modules - 1mc
Unified Intelligence in a distributed network. There is a single computer consisting of all modules on board
Synchronous and Parallel Data Processing
Allowing for greater performance and higher computing power since multiple computations can be handled in parallel simultaneously
A Key Advantage for Autonomous Vehicles
The ASG Platform allows you to create interconnected vector control systems for unmanned vehicles. Existing control systems do not have this property due to asynchronous communication between systems. ASG communication protocol results in decisions being made by several orders of magnitude faster than the current standard, making vector control possible and autonomous driving safe
Advantages for Electric Vehicles
Increasing Efficiency of the Entire Power System of the Car by Managing Energy Flows
Due to the fact that the ASG Platform allows you to combine information about the energy flows in the car with the current vector of movement, it is possible to build recovery algorithms with efficiency up to 85% or higher
The ASG platform makes it possible to improve vehicle control by controlling wheel drives based on an expanded information field
Modern Car Setup:
Over 2km of power and information wires
70-80 Control units and individual systems with their own algorithms and software
Total weight of electronics exceeds 30kg and set to rise by another 10kg by 2025
Less than 200m of power and information wires
12-14 identical ASG modules that make up all the control modules in the car
Significant reduction in weight and complexity
Low Reliability - Higher risk of damage with a larger amount of wiring
Labour Intensive - longer to install
High Cost - Copper Harnesses significantly affect the cost of the car
Higher Reliability - Due to the set up and reduced material
Time and Material Saving - cutting costs and time in production
Affordability - a reduction in overall cost of the electronics system which currently makes up 40% of vehicle cost
Technical Specifications of ASG
Characteristics of the ASG Communication Protocol
The Transfer Rate of the ASG Communication Protocol is 1.5Mbps.
In the ASG Communication Protocol, the share of useful information in the frame is constant and equal to 98%. In the CAN Protocol, it is floating and equal to 30-35% on average.
Thus, the transfer rate in ASG of 1.5 Mbps corresponds to a speed of 4.5 Mbps in the CAN Protocol, which is exceeds the speed required for stable driving when using the synchronous communication protocol.
We are working to increase this by 2-3 times in the near future.
1kHz - the Frame Rate (sync grid) - the frequency at which all ASG modules see the information state of the entire system. This frequency corresponds to processes that cover the entire car, such as the movement process.
100kHz - the frequency of tracking and monitoring processes inside each electronic module of the ASG platform. For example, tracking of the load current and short-circuit detection. In this case, the response time to the short circuit will be equal to 10 microseconds.
Tight synchronisation between these frequencies (1kHz and 100kHz) ensures vector control at all levels.
