System Outline: Notes

This vehicle is equipped with an Electronically Controlled Power Steering System (ECPS) with integrated dynamics system. Depending on the vehicle speed, the ECPS control unit controls the ECPS valve. The ECPS valve changes the power steering fluid pressure of the pressure side of the power cylinder. By controlling the power steering fluid pressure electrically, it made it possible to supply stable power steering fluid pressure to the power cylinder which ensures that the steering feel is not influenced by the fluctuation of the engine's speed, and corresponds to the driving situation. The ECPS also has two power assist control maps (sport and comfort). The control maps or "modes" are changed by the Integrated Dynamics System switch. Each mode is different and optimizes the assisting force for that mode.
