Abstract:
1. A vehicle stop determination apparatus for determining whether a vehicle is at a standstill, comprising: a vehicle speed sensor for detecting a speed of the vehicle; a G sensor for detecting a longitudinal acceleration of the 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 includes a first stop determination mode and a second stop determination mode and which selects either one of the first stop determination mode or the second stop determination mode based on the vehicle speed reduction rate calculated before the output of the vehicle speed sensor falls below a detection limit, wherein in the first stop determination mode, a stop of the vehicle is determined based on a change in the output of the G sensor when the output of the vehicle speed sensor is equal to or less than the detection limit, and in the second stop determination mode, the stop of the vehicle is determined based on a comparison between the output of the G sensor and the estimated inclination acceleration.
