The invention provides a sand brake assist apparatus and a sand brake assist method. The sand braking auxiliary equipment comprises a state module which is configured to generate a sand braking mode starting signal when a sand braking mode is started; the judging module is configured to respond to the sand braking mode opening signal and judge the effectiveness of a sensor signal related to sand braking; the detection module is configured to execute first detection to detect whether the current driving road surface of the vehicle is sand or not under the condition that the sensor signal is judged to be valid; under the condition that the detection result of the first detection is that the current driving road surface of the vehicle is not the sand, executing second detection to detect whether the current driving road surface of the vehicle is the sand again; the decision-making module is configured to decide to increase the target slip rate in the ABS by a first slip rate adjusting quantity when the detection result of the first detection is that the current driving road surface of the vehicle is sand; when the detection result of the second detection is that the current driving road surface of the vehicle is the sand, determining that the target slip rate in the ABS of the vehicle is increased by a second slip rate adjusting quantity; when it is determined that the sensor signal is invalid, a decision is made to increase a target slip rate in the ABS of the vehicle by a third slip rate adjustment amount.
本发明提供了一种沙地制动辅助设备和沙地制动辅助方法。沙地制动辅助设备包括:状态模块,配置成在开启沙地制动模式时成沙地制动模式开启信号;判断模块,配置成响应于沙地制动模式开启信号,判断与沙地制动相关的传感器信号的有效性;检测模块,配置成在判定为传感器信号有效的情况下,执行第一检测以检测车辆当前行驶路面是否为沙地;在第一检测的检测结果为车辆当前行驶路面不是沙地的情况下,执行第二检测,以再次检测车辆当前行驶路面是否为沙地;以及决策模块,配置成:在第一检测的检测结果为车辆当前行驶路面是沙地时,决策为以第一滑移率调节量增大ABS中的目标滑移率;在第二检测的检测结果为车辆当前行驶路面是沙地时,决策为以第二滑移率调节量增大车辆的ABS中的目标滑移率;在判定为传感器信号无效时,决策为以第三滑移率调节量增大车辆的ABS中的目标滑移率。
