The invention discloses an electric vehicle and a control system and a gear linkage control method thereof. The control system comprises a vehicle body controller, an intelligent cabin controller, a whole vehicle data controller, an EPB controller and a gear shifter, the vehicle body controller is in communication with the intelligent cabin controller and the whole vehicle data controller, the vehicle body controller is in communication with the EPB controller and the gear shifter, and the EPB controller is in communication with the gear shifter. And under the condition that the vehicle body controller determines that the target gear is the N gear according to the gear shifting request of the gear shifter, an N gear strategy is executed through the whole vehicle data controller, when a braking request of the EPB controller is received, a P gear strategy is executed through the whole vehicle data controller, and the electric vehicle is controlled through the intelligent cabin controller to display that the current gear is the P gear. Therefore, by canceling a P-gear controller and carrying out linkage control on the EPB and the gear shifter, gear operation is more convenient, a looped network architecture is adopted, the response speed is higher, and the vehicle driving requirement is fully met.

    本发明公开了一种电动车辆及其控制系统和档位联动控制方法。该控制系统包括:车身控制器、智能座舱控制器、整车数据控制器、EPB控制器和换挡器,车身控制器与智能座舱控制器和整车数据控制器分别进行通讯,车身控制器与EPB控制器和换挡器分别进行通讯,其中,车身控制器根据换挡器的换挡请求确定目标挡位为N档的情况下,通过整车数据控制器执行N档策略,并在接收到EPB控制器的制动请求时,通过整车数据控制器执行P档策略,且通过智能座舱控制器控制电动车辆显示当前档位为P档。由此,通过取消P档控制器,将EPB与换挡器进行联动控制,实现档位操作更加便捷,并且采用环网架构,响应速度更快,充分满足车辆驾驶需求。
