  • Patent number: 10155510
    Abstract: When it is judged that a downward slope segment exists in a scheduled traveling route, the control device of a hybrid vehicle sets a target remaining capacity SOC* in a pre-use segment in a downward slope segment and the downward slope segment to a “low-side remaining capacity Sd which is ?Sd smaller than a standard remaining capacity Sn.” Furthermore, when it is presumed that a rise amount of a remaining capacity by an extended regeneration control is large in the pre-use segment and the downward slope segment, the target remaining capacity SOC* is set to a “low-side remaining capacity Sd which is a sum of ?Sd and ?S1 smaller than the standard remaining capacity Sn.

  • Patent number: 7978127
    Abstract: In a mobile-unit positioning device, phases of pseudo noise codes carried on satellite signals from satellites are observed at a mobile unit to measure a position of the mobile unit. A pseudo distance between one of the satellites and the mobile unit is measured for every satellite during a stop of the mobile unit using an observed value of the phase acquired during a stop of the mobile unit. An error index value indicating an error of the measured distance is computed based on the distances measured at points in time during a stop of the mobile unit. A weighting factor is determined based on the index value computed for every satellite. A weighted positioning computation using the determined weighting factor is performed to determine a position of the mobile unit during movement using an observed value of the phase acquired during movement.
