The embodiment of the invention provides a steering assistance system, a steering assistance unit and a steering assistance method for a vehicle. The steering assist unit includes: an acquisition module configured to acquire an axle speed and/or a wheel speed of a vehicle during steering of the vehicle, and also acquire an accelerator pedal parameter corresponding to an operation amount of an accelerator pedal; a first determination module configured to determine a first front axle request drive torque and a first rear axle request drive torque based on the accelerator pedal parameter; a second determination module configured to determine a front axle target slip rate and a rear axle target slip rate based on the accelerator pedal parameter, and determine a second front axle request drive torque based on the front axle target slip rate and a second rear axle request drive torque based on the rear axle target slip rate; and a decision module configured to decide a smaller one of the first and second front axle request drive torques as a front axle target drive torque and a smaller one of the first and second rear axle request drive torques as a rear axle target drive torque.
本发明的实施例提供了用于车辆的转向辅助系统、转向辅助单元和转向辅助方法。该转向辅助单元包括:获取模块,构造成在车辆转向过程中获取车辆的轴速和/或轮速,并且还获取对应于油门踏板的操作量的油门踏板参数;第一确定模块,构造成基于油门踏板参数确定第一前轴请求驱动扭矩和第一后轴请求驱动扭矩;第二确定模块,构造成基于油门踏板参数确定前轴目标滑移率和后轴目标滑移率,以及基于前轴目标滑移率确定第二前轴请求驱动扭矩并基于后轴目标滑移率确定第二后轴请求驱动扭矩;以及决策模块,构造成将第一和第二前轴请求驱动扭矩中的较小者决策为前轴目标驱动扭矩,并将第一和第二后轴请求驱动扭矩中的较小者决策为后轴目标驱动扭矩。
