TLDR
In this paper, the authors proposed to stabilize the behavior of a vehicle in braking regardless of the condition of engine brake force by controlling the braking torque distribution of front and rear wheels of the vehicle within a designated range according to the engine brake torque.Abstract:
PROBLEM TO BE SOLVED: To stabilize the behavior of a vehicle in braking regardless of the condition of engine brake force by controlling the braking torque distribution of front and rear wheels of the vehicle within a designated range according to the engine brake torque of the vehicle. SOLUTION: When it is determined by a braking torque distribution rate determining means 154 that the actual distribution rate is within a decision reference range, a braking torque distribution control means 156 keeps the braking torque distribution state as it is. When it is decided that the actual distribution rate is out of the decision reference range, suitable selection is made among regulation of regenerative braking torque by a regenerative braking torque regulating means 140, regulation of engine brake torque by an engine brake torque regulating means 142, the control for the torque distribution ratio by a torque distribution ratio control means 144, and the regulation of wheel brake torque by a wheel brake torque regulating means 146 to make the actual distribution rate within the decision reference range. Thus, the behavior of the vehicle in braking can be stabilized regardless of the engine braking force.read more
