The invention discloses a multi-controller fusion-based pure electric driverless vehicle torque control system. The system comprises a driverless controller, a whole vehicle controller, a power controller and vehicle information. When a pure electric vehicle is in a driverless working mode, the driverless controller decides a current vehicle required speed; then a vehicle speed requirement is directly transmitted to the whole vehicle controller, and the whole vehicle controller obtains the current vehicle speed and the actual torque of a motor in combination with a power controller and vehicle information so as to achieve target vehicle speed control; and when the pure electric vehicle is in a conventional working mode, the whole vehicle controller directly collects vehicle information and directly calculates the required torque of the vehicle in combination with the current vehicle speed information and the actual torque information of the motor so that the vehicle is controlled, and the driving requirement of a driver is met. According to the invention, the required vehicle speed of the driverless controller can be directly transmitted to the whole vehicle controller of the pure electric vehicle, the whole vehicle controller directly calculates the vehicle required torque under the required vehicle speed, the intermediate process of torque transmission is reduced, the response time of the vehicle speed is shortened, the response precision of the vehicle speed is improved, and the riding comfort of the vehicle is increased.
本申请公开了一种基于多控制器融合的纯电动无人驾驶汽车转矩控制系统,包括无人驾驶控制器、整车控制器、动力控制器和车辆信息,纯电动汽车无人驾驶工作模式时,所述无人控制器决策出当前的车辆需求车速,然后将该车速需求直接传递到整车控制器,由整车控制器结合动力控制器和车辆信息得到当前的车速及电机的实际转矩来实现目标的车速控制;纯电动汽车常规工作模式时,整车控制器直接采集车辆信息,结合当前的车速信息、电机的实际转矩信息,直接计算得到车辆的需求转矩,实现对车辆的控制,满足驾驶员的驾驶需求。本申请能够将无人驾驶控制器的需求车速直接传递到纯电动汽车的整车控制器,由整车控制器直接计算得到需求车速下的整车需求转矩,减少了转矩传递的中间过程,降低了车速的响应时间,提高了车速的响应精度,提升了车辆的乘坐舒适性。
