  • Patent number: 11879376
    Abstract: A control method is performed to control a traction device of a motor vehicle having an internal combustion engine that includes a plurality of cylinders. Each of cylinders has at least one air intake valve, at least one exhaust valve for the combustion gases generated by the internal combustion engine, and a fuel injector. A treatment device is provided for the combustion gases that is active from an actuation temperature. The treatment device is placed downstream of the exhaust valve. The traction device includes an electrical heater for heating the combustion gas treatment device. The traction method further compares a temperature of the combustion gas treatment device with an actuating threshold temperature and actuates the electrical heater and stopping a fuel supply being supplied to one or more of the cylinders as long as the temperature of the combustion gas treatment device is below the actuating threshold temperature.

  • Patent number: 11878592
    Abstract: A control method for an electric vehicle controls braking force when the accelerator operation amount is less than a prescribed value and controls drive force when the accelerator operation amount is at least a prescribed value. The electric vehicle control method estimates disturbance torque that acts on the motor as a resistance component relating to gradient; and executes correction whereby the braking force or the drive force is increased/decreased on the basis of the disturbance torque estimated value, such that the resistance component is negated. A determination is made regarding whether or not the accelerator operation amount is a partial equivalent amount and, if at least either the accelerator operation amount on a downhill road is greater than the partial equivalent amount or the accelerator operation amount on an uphill road is less than the partial equivalent amount, the correction amount is reduced.

  • Patent number: 11880786
    Abstract: When it is necessary to charge the battery of one vehicle of a plurality of vehicles, a vehicle management computer acquires information relating to a charging facility that supplies electric power to a charge-discharge device, and information relating to the battery of another vehicle, which is different from the first vehicle, and which battery is connected to the first vehicle via the charge-discharge device. Based on the information relating to the charging facility and the information relating to the battery of the other vehicle, the vehicle management computer determines which is least expensive, a first cost associated with charging the battery of the first vehicle using the electric power that is supplied from the charging facility, or a second cost associated with charging the battery of the first vehicle using the electric power that is discharged from the battery of the other vehicle.
