<p>PROBLEM TO BE SOLVED: To prevent deterioration of deceleration due to temperature rising of a brake pad and to prevent wear of the brake pad from becoming quicker when brake force which is equal to an engine brake in a vehicle having an internal combustion engine is achieved by regenerative brake force and friction brake force.SOLUTION: When a vehicle travels a down grade, an accelerator pedal and a brake pedal are not operated, regenerative brake force and friction brake force generate brake force equal to an engine brake in a vehicle having an internal combustion engine. In this case, the regenerative brake force and the friction brake force are alternatively generated so as not to generate the friction brake force continuously in a long time.</p> |
