  • Patent number: 11970064
    Abstract: A multi-motor switching system and method for obtaining a global optimization of performance criteria that takes into account variables and conditions across an entire driving cycle. The controller of the system is adapted to conduct a global optimization in that it determines the most optimal distribution of motor loads over an entire trip or driving cycle, as opposed to sequentially determining the optimized solution for a given point of time and localized set of current condition. In one embodiment where the control system provides for global optimization, the controller receives trip information through a trip planning tool. The controller utilizes the trip information to generate a driving cycle and further incorporates this information into the optimization process performed by the controller to determine the optimal solution for the entire trip.

    Abstract: A hybrid electric vehicle and a method of controlling the same are provided to avoid a collision thereof attributable to erroneous operation of an accelerator pedal. The method includes determining whether an accelerator pedal is erroneously operated in the situation in which an obstacle is detected to be present in the traveling path. In response to determining that the accelerator pedal is erroneously operated, the method includes switching the driving mode to a mode in which an engine is disconnected from a driving shaft and a motor generates driving force. The number of revolutions per minute (RPM) of the engine is then adjusted based on the extent to which the accelerator pedal is operated and the torque of the motor is adjusted based on a first vehicle speed and the distance to the obstacle.

  • Patent number: 11623631
    Abstract: A system for controlling an internal combustion engine start threshold in a parallel hybrid-electric vehicle. A predetermined conditions tracking module determines whether or not conditions of a plurality of predetermined conditions exist. Responsive to a determination that the conditions exist, a required power estimation module estimates a next acceleration required by the vehicle and a final power requirement for the next acceleration. A propulsion system control module determines if the estimated final power requirement is between a first amount of electric motor power available at a predetermined base engine start threshold and a second amount of electric motor power available at a predetermined elevated engine start threshold. If the estimated final power requirement is between the first and second amounts of power, operation of the vehicle is controlled so as to ensure that the engine start threshold is at the predetermined elevated threshold.

    Abstract: A method of controlling traveling of an electric vehicle is provided. The method includes generating a motor torque command using a basic torque command and a virtual gear-shift intervention torque for generating a feeling of real gear shifting, while an electric vehicle travels. A motor is operated for driving the electric vehicle according to the generated motor torque command to generate the feeling thereof. Ingenerating the feeling thereof, during at least a portion of time during which the feeling thereof is generated, boost control of the motor operation is performed such that a motor torque exceeding an allowable torque of the motor is generated, and thus the generation of the feeling thereof and the boost control are performed in conjunction with each other.

  • Patent number: 11485237
    Abstract: A multi-motor switching system and method for obtaining a global optimization of performance criteria that takes into account variables and conditions across an entire driving cycle. The controller of the system is adapted to conduct a global optimization in that it determines the most optimal distribution of motor loads over an entire trip or driving cycle, as opposed to sequentially determining the optimized solution for a given point of time and localized set of current condition. In one embodiment where the control system provides for global optimization, the controller receives trip information through a trip planning tool. The controller utilizes the trip information to generate a driving cycle and further incorporates this information into the optimization process performed by the controller to determine the optimal solution for the entire trip.
