  • Patent number: 9994123
    Abstract: A controlling apparatus is provided for a vehicle including a motor, an inverter, and a battery. The controlling apparatus includes a determiner, an estimator, and a controller. The determiner judges whether a first condition is satisfied or not. The first condition is satisfied if the vehicle is in a coasting state in a regeneration prohibited mode in which a regenerative brake is disabled. The estimator estimates whether a second condition is satisfied or not. The second condition is satisfied if the motor is not to generate a regenerative torque upon a shutdown of the inverter. The controller shuts down the inverter if the determiner judges that the first condition is satisfied and the estimator estimates that the second condition is satisfied.

  • Publication number: 20170282926
    Abstract: A regeneration control apparatus which controls a regenerative braking force of an electric motor for driving an electric motor vehicle includes: a regeneration operation unit operated by a driver to select magnitude of the regenerative braking force stepwise from selection stages; a default operation unit operated by the driver to change the magnitude of the regenerative braking force to one of the selection stages which has been set as a default stage; a detection unit detecting an operation state on the regeneration operation unit during a learning period; and a default stage changing unit, when one of the selection stages whose selection frequency is highest during the learning period is different from one of the selection stages which has been currently set as the default stage, changing the default stage to another selection stage.

  • Patent number: 9694711
    Abstract: A controlling apparatus is provided for controlling a vehicle including a motor for traveling and an inverter for driving the motor. The controlling apparatus includes: an obtainer acquiring information on a front of the vehicle; a determiner judging whether the vehicle is in a coasting state in a regeneration prohibited mode in which a regenerative brake is disabled or not; an estimator forming, if the determiner judges that the vehicle is in the coasting state in the regeneration prohibited mode, an estimate of whether the coasting state in the regeneration prohibited mode is to last for at shortest a predetermined period or not on a basis of the information acquired by the obtainer; and a controller shutting down the inverter if the estimator estimates that the coasting state in the regeneration prohibited mode is to last for at shortest the predetermined period.
