The invention relates to an in-line electric car rear wheel steering self-balancing control device. The device comprises a rotation speed sensor, a car body inclination sensor, a front wheel turning angle sensor, a controller and a rear wheel steering system. The rotation speed sensor is arranged at an electric car rear wheel motor. The car body inclination sensor and the controller are both fixedly arranged on an electric car frame. The front wheel turning angle sensor is arranged at the hinged joint of a steering column and a car frame front tube. The rotation speed sensor, the car body inclination sensor and the front wheel turning angle sensor are connected to the controller. The two ends of the rear wheel steering system are fixedly connected with the electric car frame and electric car rear wheels correspondingly. When a car makes a turn, if the car has to avoid the dangerous circumstance, the turning angle of front wheels are changed, then the car is out of balance, and the rear wheels are controlled for auxiliary steering, so that the car is kept balanced; and in the ultra-low speed running or stopping and waiting process of the car, the rear wheels are used for steering to change the overall gravity center so that the balance is kept, and the ultra-low speed running safety and stopping and waiting comfort are improved.
Description
technical field [0001] The patent of the present invention relates to the field of in-line two-wheel electric vehicles, in particular to a rear-wheel steering self-balancing control device for in-line two-wheel electric vehicles and a rear-wheel steering self-balancing control method for in-line electric vehicles. Background technique [0002] In-line two-wheel electric vehicles are still the preferred choice for people to travel because of their economy and simplicity. Ordinary two-wheeled electric vehicles are relatively safe when running in a straight line, but when turning, because of their specific mechanical structure, the corner of the front wheel must be kept at a fixed angle by the rider according to the speed, and cannot change, otherwise It will not be possible to keep the vehicle in balance. At this time, if there are obstacles or emergencies in front of the vehicle, excessive steering of the front wheels or sudden braking are used to dodge, which often causes t...
