Abstract

A braking force control device capable of properly adjusting braking force distribution on wheels and furthest ensuring braking force in a situation that collision with an obstacle may happen is provided. An AEB controller performs automatic braking control (step S2) when a vehicle is determined to be possibly collided with an obstacle, then an ESP controller switches a mapping used for EBD control from a first braking force distribution mapping to a second braking force distribution mapping (step 3), and then the ESP controller performs EBD control according to the second braking force distribution mapping. In the step S4, the ESP controller controls braking force distribution in a manner that braking hydraulic pressure of rear wheels (5) is kept at a value higher than braking hydraulic pressure when the AEB controller (51) is determined to be impossibly collided.

Description

technical field [0001] The invention relates to a braking force control device. Background technique [0002] In recent years, as a safety measure in vehicles such as automobiles, some vehicles are equipped with ABS devices that prevent wheel lock during braking, and automatic braking that prevents collisions by judging the risk of collision between the vehicle and objects located around the vehicle. device. [0003] As a braking force control device for such a vehicle, a braking force control device described in Patent Document 1 is known. The braking force control device described in Patent Document 1 suppresses further increase in brake fluid pressure when the ABS device is already activated when the automatic braking device is activated. [0004] According to this braking force control device, when there is a risk of wheel lock during automatic braking operation, the ABS device operates to maintain the brake fluid pressure, so that the wheel lock can be prevented and t...
