Abstract
提供一种车辆的制动控制装置，其能够减少由于ACC的自动制动功能引起的车辆的减速度持续长时间超过既定的限制值的可能。车辆的制动控制装置具备目标制动转矩设定部(91，101)和控制部(93，103)，前述目标制动转矩设定部(91，101)基于制动要求的信息(T_req_in)设定目标制动转矩(T_out)，前述制动要求的信息(T_req_in)被基于本车辆和先行车辆的目标车间距离设定，前述控制部(93，103)基于目标制动转矩(T_out)控制车辆的制动力，目标制动转矩设定部(91，101)在本车辆的减速度(Ax)超过既定的限制值(Ax_lim)时，将比指示制动转矩(T_req_in)小的值的限制制动转矩(T_lim)设定成目标制动转矩(T_out)。

Provided is a vehicle brake control device which can reduce the possibility that the deceleration duration of a vehicle due to the automatic braking function of an ACC exceeds a predetermined limit value for a long time. A vehicle brake control device is provided with a target brake torque setting unit (91,101) and a control unit (93,103), wherein the target brake torque setting unit (91,101) sets a target brake torque (T_out) based on information (T_req_in) of a brake request, the information (T_req_in) of the brake request is set based on a target inter-vehicle distance between the vehicle and a preceding vehicle, the control unit (93,103) controls the braking force of the vehicle based on the target brake torque (T_out), and the target brake torque setting unit (91,101) sets a limit brake torque (T_lim) smaller than a value indicating the brake torque (T_req_in) as the target brake torque (T_out) when the deceleration (Ax) of the vehicle exceeds a predetermined limit value (ax_lim).
