Abstract:
1. A drive assist apparatus which performs driving assistance in a predetermined interval having a gradient, comprising: average gradient information acquisition means for acquiring first average gradient information, from a start position within the predetermined interval to a stop position within the predetermined interval, from an external infrastructure, and second distance information, from the start position to a present position of the host vehicle; driving status information acquisition means for acquiring driving status information of a host vehicle in the predetermined interval; and gradient estimation means for estimating second average gradient information, from the present position within the predetermined interval to the stop position within the predetermined interval, based on the first average gradient information acquired by the average gradient information acquisition means, the driving status information of the host vehicle that is acquired by the driving status information acquisition means, and the second distance information acquired by the average gradient information acquisition means, wherein the drive assist apparatus performs driving assistance, from the present position to the stop position, using the second average gradient information that is estimated by the gradient estimation means.
