The Renesas two wheeler start-stop reference solution automatically switches off the engine when the vehicle is at a standstill, and restarts it as soon as the driver presses the clutch pedal or releases the brake. Based on the high performance and low power 16-bit RL78/F12 MCU, this reference solution offers real time debugging, easily accessible programming and debugging ports, and all the required inputs and outputs.

The ability of a vehicle to automatically stop its engine when stationary, and then fire up again when it’s time to move, could lead to significant fuel savings and reduction in vehicle emissions, according to Navigant Research.

This reference solution comes with schematics, reference firmware and software tools that are freely available on request.
