Development of Electronic Control System for Formula One

Article of Honda R&D Technical Review F1 Special (The third Era Activities)

Summary

The application of electronic control systems has been rapidly increasing in Formula One cars as well as in other vehicles. System performance is a crucial element in conducting precision control and measurement of cars.
Starting with the 2006 season, the Honda works has been working to apply original Honda systems not only in the engine control system, as before, but in all vehicle electronic control systems.
In order to pursue higher performance at the same time as enhanced in-vehicle mountability in Formula One electronic control systems, it is necessary to carry out optimization of these systems together with thoroughgoing miniaturization. On-board systems have an electronic control unit (ECU) with integrated functionality linked by a high-speed network with units located in every part of the vehicle. High-speed telemetry is used to coordinate these with the garage system in order to optimize systems.
The enhancement of unit performance by means of higher speed and greater precision contributes to heightened controllability, and particularly to enhanced precision of driving force control and gearbox control. High-speed communication also contributes to greater measurement performance in the pit.
