HYBRID ELECTRIC VEHICLE AND METHOD FOR CONTROLLING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17988673 titled 'HYBRID ELECTRIC VEHICLE AND METHOD FOR CONTROLLING THE SAME

Simplified Explanation

The patent application describes a hybrid electric vehicle that includes an engine, two motor-generators, and a controller. The controller can operate the vehicle in different modes, including an EV mode using one motor-generator, a second EV mode using both motor-generators, or a series mode using the engine to power the second motor-generator.

  • The hybrid electric vehicle includes an engine, two motor-generators, and a controller.
  • The controller can set the vehicle's operation in different modes, including EV mode and series mode.
  • The controller compares the vehicle's speed with a reference speed and controls the vehicle to drive in the second EV mode when the speed is below the reference speed.

Potential applications of this technology:

  • Hybrid electric vehicles can be used in various transportation sectors, including personal cars, public transportation, and commercial vehicles.
  • This technology can help reduce fuel consumption and emissions, making vehicles more environmentally friendly.
  • The ability to switch between different modes allows for optimal power management and efficiency.

Problems solved by this technology:

  • Hybrid electric vehicles address the issue of high fuel consumption and emissions associated with traditional internal combustion engines.
  • The ability to operate in different modes provides flexibility in power management, allowing for better efficiency and reduced reliance on the engine.

Benefits of this technology:

  • The hybrid electric vehicle can achieve better fuel efficiency and lower emissions compared to traditional vehicles.
  • The ability to operate in EV mode allows for silent and zero-emission driving, particularly in urban areas.
  • The controller's control strategy based on vehicle speed helps optimize power usage and improve overall efficiency.


Original Abstract Submitted

Disclosed is a hybrid electric vehicle comprising an engine configured to generate power by burning a fuel, first and second motor-generators configured to generate power or assist the engine, and a controller. The controller may be configured to set an operation of a first EV mode using the second motor-generator, a second EV mode using the first and second motor-generators, or a series mode of driving the second motor-generator by using power generation of the engine, compare a speed of the vehicle with a reference speed based on that the engine is in an off state, and may be configured to perform a control so that the vehicle drives in the second EV mode when the speed of the vehicle is less than the reference speed.
