The invention provides a vehicle turning braking force distribution method and device, electronic equipment and a storage medium, and can be applied to the technical field of vehicle brake-by-wire. When the turning braking demand information is detected, the real-time state information of the vehicle is obtained, and then the initial braking force of the vehicle is distributed according to the longitudinal lateral acceleration and the first brake pedal displacement in the real-time state information; inputting a first longitudinal vehicle speed and a first steering wheel angle in the real-time state information into the linear two-degree-of-freedom vehicle model to obtain a second yaw velocity and a second centroid deviation angle of the vehicle; the additional yaw moment of the vehicle is calculated according to the first yaw velocity, the first centroid deviation angle, the second yaw velocity and the second centroid deviation angle, and then secondary braking force distribution is conducted on the vehicle according to the additional yaw moment; according to the invention, the stability and safety of the vehicle in the driving process can be effectively improved.
本申请提供了一种车辆转弯制动力分配方法和装置、电子设备及存储介质,可应用于车辆线控制动技术领域。本申请通过在检测到转弯制动需求信息时,获取车辆的实时状态信息,再根据实时状态信息中的纵向侧向加速度和第一制动踏板位移对车辆进行初始制动力分配,接着将实时状态信息中的第一纵向车速和第一方向盘转角输入线性二自由度汽车模型,得到车辆的第二横摆角速度和第二质心偏侧角后,根据第一横摆角速度、第一质心偏侧角、第二横摆角速度和第二质心偏侧角计算车辆的附加横摆力矩,然后根据附加横摆力矩对车辆进行二次制动力分配;本申请可以有效提高车辆行驶过程中的稳定性和安全性。
