FIELD: transport.SUBSTANCE: device for vehicle deceleration factor calculation consists of driving force request unit, speed request unit, acceleration request unit and deceleration factor calculation unit. The deceleration factor calculation unit calculates multiple deceleration factors based on correlation between obtained driving force, speed and acceleration. In this system, the deceleration factor calculation unit changes deceleration factor to be calculated based on vehicle driving condition. In the other version, the deceleration factor calculation unit also calculates air resistance factor. Additionally, there can be optional version where the deceleration factor calculation unit calculates resistance to motion.EFFECT: fine precision of deceleration factor calculation.17 cl, 10 dwg |
