The invention relates to the technical field of two-wheel electric vehicles, solves the technical defects that accidents are easy to occur in the riding process of going up and down a slope and turning, and damping of a front fork shock absorber cannot be adjusted along with the change of the slope of a road surface, and adopts the technical scheme that a main control module is connected with a controller to control the operation of a vehicle, and an IMU (Inertial Measurement Unit) inertia detection module detects the posture and speed of a vehicle body; the electromagnetic damper is used as a damping-adjustable front fork shock absorber, and when the electric vehicle runs uphill and downhill, the main control module correspondingly and automatically adjusts the damping of the electromagnetic damper; in the uphill process, when a speed regulation control signal of the speed regulation rotating handle reaches a peak value, the main control module controls the driving motor to decelerate to a speed interval of maximum torque output to operate; and in the turning and/or downhill process, the main control module limits the driving motor to run at a speed of half speed or lower than half speed. The damping of the front fork shock absorber is adjustable, intelligent speed regulation control can be achieved in the uphill, downhill and turning processes, accidents caused by misoperation of a speed regulation rotating handle are avoided, and safety is higher.
本发明涉及两轮电动车技术领域,解决上、下坡及转弯骑行过程中易发生事故,且前叉避震器的阻尼不能随路面坡度变化进调节的技术不足,解决方案:主控模块与控制器连接以控制车辆运行,IMU惯性检测模组检测车身姿态和速度,电磁阻尼器作为阻尼可调的前叉避震器,电动车上、下坡行驶时,主控模块相应地自动调节电磁阻尼器的阻尼;上坡过程中,调速转把的调速控制信号达到峰值时,主控模块控制驱动电机降速至其最大扭矩输出的速度区间运行;转弯和/或下坡过程中,主控模块限制驱动电机以半速或者半速以下减速运行。本发明前叉避震器的阻尼可调,上、下坡及转弯过程中可实现智能调速控制,避免了因误操作调速转把而引起的事故,安全性更高。
