System Description: Features: Link-Less
The Electric Throttle Control Actuator is used. This is a link-less system that does not use an accelerator cable. Instead, it uses an accelerator pedal position sensor and a throttle position sensor to detect the accelerator pedal position and the throttle position.
The hybrid vehicle ECU calculates the target engine speed and the required engine motive force in accordance with the signals provided by the accelerator pedal position sensor, vehicle driving conditions, and the SOC (state of charge) of the hybrid vehicle battery. The hybrid vehicle ECU sends the results of this calculation to the ECM via the CAN communication line. The ECM optimally controls the electric throttle control actuator and sends the actual engine speed signal to the hybrid vehicle ECU.
