Braking force control device and braking force control method

摘要

A braking force control device and method performs brake assist control. A timer CT begins to count the elapsed time, for example, from when the elevation gradient DELTAPM/C of a master cylinder pressure PM/C becomes equal to or greater than a first threshold value TH2. It is determined that an emergency brake operation is executed, when the master cylinder pressure PM/C becomes equal to or greater than a second threshold value TH1 before a predetermined time has passed, and then the brake assist control starts.
