CONTROL APPARATUS FOR ELECTRIC VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18483616 titled 'CONTROL APPARATUS FOR ELECTRIC VEHICLE

Simplified Explanation: The patent application describes a control apparatus for an electric vehicle with features like an electric motor, a high-low switching device, a center differential, and a high-low selection device. It includes a creep control portion that generates a creep torque during vehicle stops and can be stopped under certain conditions.

  • The control apparatus includes an electric motor for powering the vehicle.
  • A high-low switching device is used to establish either a high gear position or a low gear position.
  • A center differential transmits rotation output to the front and rear wheels while allowing differential rotation between them.
  • A high-low selection device chooses the gear position to be set in the high-low switching device.
  • The creep control portion generates a creep torque during vehicle stops.
  • A creep cut can be executed to stop the creep control under specific conditions.
  • The creep cut is halted when the low gear position is selected during its execution.

Key Features and Innovation:

  • Electric motor for powering the vehicle.
  • High-low switching device for gear position selection.
  • Center differential for transmitting rotation to wheels.
  • High-low selection device for choosing gear position.
  • Creep control portion for generating creep torque during stops.
  • Creep cut feature to stop creep control under certain conditions.

Potential Applications: This technology can be applied in electric vehicles, particularly in controlling the vehicle's movement during stops and gear shifting.

Problems Solved: This technology addresses the need for efficient control of electric vehicles during stops and gear selection, enhancing overall performance and user experience.

Benefits:

  • Improved control during vehicle stops.
  • Enhanced efficiency in gear shifting.
  • Better overall performance of electric vehicles.

Commercial Applications: The technology can be utilized in the development of electric vehicles, contributing to their performance and user experience, potentially attracting customers looking for advanced control features in their vehicles.

Prior Art: Further research can be conducted on similar control apparatus for electric vehicles to understand the existing technology landscape in this field.

Frequently Updated Research: Stay updated on advancements in electric vehicle control systems and technologies to leverage the latest innovations in this field.

Questions about Electric Vehicle Control Apparatus: 1. What are the key components of the control apparatus for an electric vehicle described in the patent application? 2. How does the creep control portion enhance the performance of the electric vehicle during stops?


Original Abstract Submitted

A control apparatus for an electric vehicle that includes (i) an electric motor, (ii) a high-low switching device configured to establish a high gear position or a low gear position, (iii) a center differential configured to transmit rotation outputted from the high-low switching device, to the front and rear wheels, while allowing differential rotation between the front and rear wheels, and (iv) a high-low selection device configured to select the high gear position or low gear position that is to be established in the high-low switching device. The control apparatus includes a creep control portion configured to execute a creep control for generating a creep torque during stop of the vehicle. The creep control portion executes a creep cut for stopping the creep control under a predetermined constant condition, and stops the execution of the creep cut when the low gear position is selected during execution of the creep cut.
