CONTROLLER AND CONTROL METHOD FOR VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18323713 titled 'CONTROLLER AND CONTROL METHOD FOR VEHICLE

Simplified Explanation

The patent application describes a vehicle system that includes sensors and a controller for controlling the vehicle speed.

  • The vehicle system includes an accelerator sensor, a vehicle speed sensor, and a gradient sensor.
  • The controller calculates the driving force required to move the vehicle based on the vehicle speed and accelerator pedal operation.
  • The controller also controls the vehicle speed to maintain a constant target speed using a cruise control process.
  • The cruise control process is executed if the difference between the maximum and minimum vehicle speeds within a specified time period is within a specified value.
  • The controller also considers the traveling resistance and gradient resistance in calculating the driving force.
  • The cruise control process is executed if the sum of the traveling resistance and gradient resistance is greater than or equal to the driving force.


Original Abstract Submitted

A vehicle includes an accelerator sensor, a vehicle speed sensor, and a gradient sensor. A controller for the vehicle is configured to execute a calculating process that calculates a traveling driving force required to move the vehicle forward based on a vehicle speed and an operation amount of an accelerator pedal, and a cruise control process that controls the vehicle speed such that the vehicle speed becomes a constant target vehicle speed. The controller is configured to execute the cruise control process on condition that a difference between a maximum value and a minimum value of the vehicle speed within a specified time period is less than or equal to a specified value, and a sum of a traveling resistance calculated based on the vehicle speed and a gradient resistance calculated based on the gradient of the road surface is greater than or equal to the traveling driving force.
