Patent number: 8981717Abstract: The usage pattern of an electric vehicle including the amount of power consumption of a battery on each day of the week is extracted from usage histories of the vehicle in a predetermined period. When the vehicle goes home after one day's operation and is connected to a charging apparatus, a charge determination unit predicts a usage pattern of the vehicle on the next day and determines whether the vehicle can operate on the next day with the remaining amount of power of a battery in the vehicle. When it is determined that the charging of the battery is necessary, the battery is charged until it reaches the target remaining amount of power. The target remaining amount of power is determined on the basis of the amount of power consumption in the predicted usage pattern so that the full charge is prevented and the number of charges is reduced.Type: GrantFiled: April 2, 2012Date of Patent: March 17, 2015Assignee: Honda Motor Co., LtdInventors: Masanori Hayashi, Koichiro Takemasa, Taisuke Tsurutani

Patent number: 8706374Abstract: An accelerator pedal device provided with a driving control device. The driving control device generates a braking force for braking a vehicle when the operation quantity of an acceleration pedal is below a first threshold value, and generates a driving force for driving the vehicle when the operation quantity exceeds a second threshold value larger than the first threshold value. The driving control device does not generate either the driving force or the braking force, and allows the vehicle to drive inertially, when the operation quantity ranges from the first threshold value to the second threshold value.Type: GrantFiled: February 16, 2011Date of Patent: April 22, 2014Assignee: Honda Motor Co., Ltd.Inventors: Hirotaka Takiguchi, Yoichi Sugimoto, Koichiro Takemasa, Taisuke Tsurutani
