DRIVING FORCE CONTROL DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17820336 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 when switching between automated and manual driving modes. Here are the key points:

  • The device controls the driving force based on an override driving force characteristic, which specifies the target acceleration according to the vehicle speed, accelerator pedal position, and traveling resistance.
  • In the override driving force characteristic, the longitudinal acceleration at a fully closed accelerator pedal position is higher than in the manual-driving-mode driving force characteristic.
  • The inclination of the graph representing the relationship between the accelerator pedal position and longitudinal acceleration is smaller in the override driving force characteristic compared to the manual-driving-mode driving force characteristic at the same accelerator pedal position.

Potential applications of this technology:

  • Automated driving systems: The device can be used in vehicles equipped with automated driving systems to smoothly transition between automated and manual driving modes.
  • Electric vehicles: The control device can optimize the driving force characteristics for electric vehicles, taking into account factors like vehicle speed, accelerator pedal position, and traveling resistance.

Problems solved by this technology:

  • Smooth transition between driving modes: The device ensures a seamless shift from automated to manual driving modes by adjusting the driving force characteristics based on various factors.
  • Enhanced driving experience: By controlling the driving force characteristics, the device can provide a more responsive and efficient driving experience for the driver.

Benefits of this technology:

  • Improved safety: The device helps maintain stability and control during the transition between driving modes, enhancing overall safety.
  • Optimal driving performance: By adjusting the driving force characteristics, the device can optimize the vehicle's acceleration and responsiveness, resulting in improved performance.
  • Energy efficiency: The control device takes into account traveling resistance and other factors to optimize the driving force, potentially leading to increased energy efficiency in electric vehicles.


Original Abstract Submitted

A driving force control device in which, when an automated driving mode is shifted to a manual driving mode, a driving force is controlled based on an override driving force characteristic specifying target acceleration according to a vehicle speed, a accelerator pedal position, and a traveling resistance to the vehicle, a longitudinal acceleration at a fully closed accelerator pedal position in the override driving force characteristic is higher than the longitudinal acceleration at the fully closed accelerator pedal position in the manual-driving-mode driving force characteristic, and an inclination of a graph representing a relationship between the accelerator pedal position and the longitudinal acceleration in the override driving force characteristic is smaller than the inclination of the graph representing the relationship between the accelerator pedal position and the longitudinal acceleration in the manual-driving-mode driving force characteristic at a same accelerator pedal position.
