The invention provides a drive control method of a hybrid vehicle and the vehicle, and relates to the technical field of vehicles. The driving control method of the hybrid vehicle comprises the steps that a torque control target is set according to the state of the vehicle; determining boundary conditions according to the torque control target and the adaptive factor, and determining an optimal control sequence of torque distribution according to a pre-established vehicle model and the corresponding boundary conditions; a torque distribution mode is determined according to the optimal control sequence, and the torque distribution mode comprises a front axle torque distribution mode, a left rear wheel torque distribution mode and a right rear wheel torque distribution mode. Distribution of the torque of the front axle, the torque of the left rear wheel and the torque of the right rear wheel can be achieved, so that a distributed driving strategy can be applied to the hybrid vehicle, and engines can intervene in a system in parallel or in series in a hybrid mode. In addition, by setting the adaptive factor, the upper and lower limits can be adaptively adjusted, so that the situation that the prediction result breaks through the boundary due to the inaccurate model can be avoided.
本发明提供了一种混动车辆的驱动控制方法及车辆,涉及车辆技术领域。本发明所述的混动车辆的驱动控制方法包括:根据车辆状态设定扭矩控制目标;根据所述扭矩控制目标和自适应因子确定边界条件,根据预先建立的车辆模型和对应的所述边界条件确定扭矩分配的最优控制序列;根据所述最优控制序列确定扭矩分配模式,其中,所述扭矩分配模式包括前轴扭矩、左后轮扭矩和右后轮扭矩的分配模式。本发明可以实现前轴扭矩、左后轮扭矩和右后轮扭矩的分配,从而能够在混动车辆中应用分布式驱动策略,在混动模式中可以使得发动机并联或串联介入系统。另外,通过设置自适应因子,可以自适应调整上下限,从而可以避免模型不准确带来的预测结果突破边界的情况。
