AI Technical Summary

Technical Problem

Existing vehicle brake control systems lack the ability to appropriately perform brake assist control and decelerate the vehicle based on driver input, especially in situations requiring rapid deceleration due to proximity to obstacles.

Method used

A vehicle brake control device with a first and second brake operator, detection devices for operation amounts, an external information acquisition system, and a control unit that executes deceleration and brake assist control based on external information and operation conditions, allowing for appropriate braking force and deceleration control.

Benefits of technology

Enables effective brake assist control and deceleration by utilizing external information and operation thresholds, reducing the need for additional sensors and components, and providing a compact design with adjustable braking force control.

Abstract

The present invention provides a vehicle brake control device that can appropriately perform brake assist control and decelerate the vehicle when the driver applies the brakes. [Solution] The vehicle brake control device comprises a first brake operator for operating the first brake, a second brake operator for operating the second brake, a second detection device for detecting a second operation amount corresponding to the operation of the second brake operator, an external information acquisition device for acquiring external information about the vehicle's surroundings, and a control unit. The control unit is capable of performing deceleration control to slow down the vehicle based on a target deceleration of the vehicle set based on external information and a vehicle deceleration obtained by calculation, etc. If the operating conditions for deceleration control are met (S4:Yes) and the second operation amount is equal to or greater than the first threshold (S3:Yes), the control unit performs brake assist control to slow down the vehicle with a deceleration corresponding to the second operation amount (S5).
