AI Technical Summary

Technical Problem

Existing technologies result in reduced vehicle deceleration when the accelerator pedal input is small, causing discomfort to the user, and there is insufficient research on braking force control methods suitable for this situation.

Method used

The braking force control device calculates the target acceleration based on the accelerator pedal operation and controls the transmission system and brakes to generate braking force, ensuring that the braking force meets the user's expectations, including braking force within the range allowed by the transmission system and the excess force supplemented by the brakes.

Benefits of technology

It reduces the discomfort caused by changes in deceleration while driving, adapts to different operating methods, and improves driving convenience.

Abstract

The present application provides a control device, comprising: a calculation unit that calculates a first braking force based on an accelerator pedal operation of a driver; an acquisition unit that acquires a driveline producible braking force; and an instruction unit that, based on the first braking force and the driveline producible braking force, outputs a request to generate the first braking force to the driveline or the driveline and a brake, and notifies a device for driving assistance or the like of information related to a brake pedal operation of the driver.
