DRIVING FORCE CONTROL DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17932438 titled 'DRIVING FORCE CONTROL DEVICE

Simplified Explanation

The abstract describes a driving force control device that adjusts the driving force of a vehicle based on various factors such as vehicle speed, accelerator pedal position, and traveling resistance. The device has an override driving force characteristic that specifies a target acceleration and is different from the manual-driving-mode driving force characteristic.

  • The override driving force characteristic has a higher longitudinal acceleration at a fully closed accelerator pedal position compared to the manual-driving-mode driving force characteristic.
  • The override driving force characteristic and the manual-driving-mode driving force characteristic have graphs representing the relation between accelerator pedal position and longitudinal acceleration.
  • These graphs intersect at a specific accelerator pedal position that is different from fully closed and fully opened positions.

Potential applications of this technology:

  • Automotive industry: The driving force control device can be implemented in vehicles to enhance control and performance based on different driving modes.
  • Autonomous vehicles: The device can be utilized in autonomous vehicles to adjust the driving force based on various factors and optimize acceleration.

Problems solved by this technology:

  • Inconsistent acceleration: The device ensures that the longitudinal acceleration is controlled appropriately based on the override driving force characteristic, providing a smoother driving experience.
  • Adaptability to driving conditions: By considering factors such as vehicle speed and traveling resistance, the device can adjust the driving force to suit different driving conditions.

Benefits of this technology:

  • Improved control: The override driving force characteristic allows for precise control of the driving force, enhancing the overall driving experience.
  • Optimal acceleration: The device adjusts the longitudinal acceleration based on the specific accelerator pedal position, ensuring efficient and safe acceleration.


Original Abstract Submitted

In a driving force control device, a driving force is controlled based on an override driving force characteristic specifying a target acceleration according to a vehicle speed, an accelerator pedal position, and a traveling resistance to a vehicle, a longitudinal acceleration at a fully closed accelerator pedal position is higher in an override driving force characteristic than in a manual-driving-mode driving force characteristic, and a graph representing a relation between the accelerator pedal position and the longitudinal acceleration in the override driving force characteristic and a graph representing a relation between the accelerator pedal position and the longitudinal acceleration in the manual-driving-mode driving force characteristic intersect at a specific accelerator pedal position different from a fully closed position and a fully opened position.
