Traveling speed pattern estimation device and hybrid vehicle drive control device

摘要

PPROBLEM TO BE SOLVED: To easily estimate the pattern of running speed on a running route. PSOLUTION: Running data and environmental data regarding the running route are memorized corresponding to each other, and the route run through more than specific number of times is specified as a frequent route. The frequent route is divided into multiple small intervals by specifying positions in which the running thought being stable from the running data, candidates of the pattern of running speed for each small interval is extracted, and thereby the estimated pattern of running speed of the frequent running route is outputted. The small interval is not divided at the unstable running points, but divided at the stable running points, and therefore the running states of both the ends of the small interval are stable. As the results, the conditions of both the ends can be thought that they are equivalent, and therefore the only small intervals can be independently analyzed without consideration to the influence from the running states of the before-and-after small intervals.
