Abstract
A vehicle stop determination apparatus includes a vehicle speed sensor for detecting a speed of a vehicle, a G sensor for detecting a longitudinal acceleration of a vehicle, an inclination acceleration estimate section for calculating an estimated inclination acceleration resulting from an inclination of a road surface based on a vehicle speed reduction rate calculated from an output of the vehicle speed sensor and an output from the G sensor, and a stop determination section which has a first stop determination mode and a second stop determination mode and which selects the first stop determination mode or the second stop determination mode based on the vehicle speed reduction rate provided before the output of the vehicle speed sensor becomes equal to or less than a detection limit. Also, the inclination is re-determined based on the output of the G sensor when the vehicle is stopped.
