The invention relates to a vehicle steering control method and device, a controller and a vehicle. The method comprises the steps that: vehicle speed and vehicle transverse acceleration are obtained;a reference torque distribution proportion is obtained according to the vehicle transverse acceleration, the vehicle speed and a first corresponding relation; and the steering torque distribution proportion of a vehicle is obtained based on the reference torque distribution proportion, and four-wheel drive torque distribution during vehicle steering is controlled according to the steering torque distribution proportion, so that vehicle steering is controlled. Therefore, accurate four-wheel drive torque distribution can be calculated when the vehicle is in a steering working condition. The method is simple, reliable and high in robustness. With the method adopted, it can be guaranteed that the steering insufficiency degree of the vehicle under the steering running working condition is within an optimal range, it can be guaranteed that the four-wheel drive torque distribution under the steering running working condition is reasonable, and the controllability, driving performance and safety performance of the vehicle are improved to a certain degree.
本公开涉及一种车辆转向控制方法、装置、控制器及车辆,包括获取车速和车辆横向加速度;根据车辆横向加速度、车速和第一对应关系得到基准扭矩分配比例;基于基准扭矩分配比例获取车辆的转向扭矩分配比例,并根据转向扭矩分配比例控制所述车辆转向时的四驱扭矩分配,从而控制车辆转向。这样能够在车辆处于转向工况时计算出准确地四驱扭矩分配,简单可靠,鲁棒性强,可以保证车辆转向行驶工况时的转向不足度处于较优的范围内,能够确保转向行驶工况四驱扭矩分配合理,使得车辆的可操控性、驾驶性能和安全性能都得到了一定程度的提升。
