The invention relates to a vehicle anti-pitch operation during near stop condition. A brake torque control system of a host vehicle includes a memory and a brake torque control module. For a braking event, the memory stores a plurality of values indicating whether an object in front of the host vehicle has been detected, a rate of the host vehicle, and an expected stop distance or an expected stop position of the host vehicle. The brake control module operates in an anti-pitch mode based on the value, and reduces at least one of an amount of requested brake torque and applied brake pressure for a last remainder of the braking event to reduce pitch of the host vehicle before a full stop is reached, and does not reduce the at least one of the amount of requested braking torque and the applied braking pressure for a portion of the braking event that precedes a last remaining portion of the braking event.
本发明涉及在接近停止状态条件期间的车辆防俯仰操作。一种主车辆的制动扭矩控制系统包括存储器和制动扭矩控制模块。对于制动事件,存储器存储指示是否已经检测到主车辆前方的物体、主车辆的速率以及主车辆的预期停止距离或预期停止位置的多个值。制动控制模块基于所述值在防俯仰模式下操作,并且对于制动事件的最后剩余部分减小请求的制动扭矩的量和施加的制动压力中的至少一个,以在达到完全停止之前减小主车辆的俯仰,并且对于在制动事件的最后剩余部分之前的制动事件的一部分不减小请求的制动扭矩的量和施加的制动压力中的所述至少一个。
