  • Patent number: 11458950
    Abstract: A drive force control system configured to reduce a total energy consumption of a hybrid vehicle. The drive force control system calculates: an output power of the engine which can optimize a thermal efficiency given that the engine is operated at a best fuel point; and a required electric power to be supplied from a battery or to be generated by a control motor, which can adjust the drive power established by the output power of the engine to the required power. A power exchange between the control motor and the battery is interrupted if the required electric power to be supplied from the electric storage device or to be generated by the control motor is less than a first predetermined electric power.

  • Patent number: 10794249
    Abstract: An amount of deposition of intramural PM in a particulate filter is estimated with a high degree of accuracy. A controller obtains, as a correlation between a reference value of an intramural PM deposition amount and an oxygen storage capacity of the catalyst, a change over time of an oxygen storage capacity of the catalyst according to a change of a filter PM deposition amount in a period of time from a point in time at which the filter PM deposition amount is substantially zero to a point in time at which the oxygen storage capacity of the catalyst, which becomes larger according to an increase of the filter PM deposition amount, reaches a maximum value. Further, the controller estimates a current intramural PM deposition amount based on a current oxygen storage capacity of the catalyst and the correlation.
