Embodiment Construction
[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0040] The present invention is a two-wheel drive electric vehicle with active differential speed control. Based on the concept that "the center of gravity of the vehicle is located below the horizontal centerline of the axle to realize the static self-balancing of the vehicle", its model can be simplified as a tumbler with one degree of freedom.
[0041] The present invention is a two-wheel drive electric vehicle with active differential control, such as figure 1 As shown, a cube-shaped bottom box structure 1 including an opening at the top, such as Image 6 As shown, the front end of the bottom box structure 1 is provided with a wireless charging device 25, such as figure 1 As shown, the upper part of the bottom box structure 1 is provided with a cab unit, and both lateral sides of the bottom box structure 1 are connected with a driving un...

The invention discloses a two-wheel drive electric vehicle with active differential control, comprises a cubic bottom box structure body with a top end opening, a wireless charging device is arrangedat the front end of the bottom box structure body, a cab unit is arranged at the upper part of the bottom box structure body, and both lateral sides of the bottom box structure body are connected witha driving unit and a brake through a box shock absorber; An electrical drive unit is also provided in the bottom box structure. The two-wheel drive vehicle of the invention has the advantages of simple structure, spacious lateral space in the vehicle, compact front and rear structure, and saving the space of the front engine compartment. Under no-load or full-load condition, the center of gravityof the whole vehicle is located below, and it has static stability (self-balance); The central processing unit (CPU) collects the pitch angle data in real time through the inertial measurement unit (IMU), and controls the wheel drive motor to output the corresponding torque to restrain the pitch fluctuation of the vehicle in the driving process. The wheel drive motor is directly connected with the driving wheel, and the driving transmission efficiency is high, and the feedback braking energy recovery rate is high.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to a two-wheel drive electric vehicle with active differential speed control. Background technique [0002] In order to alleviate air pollution and achieve sustainable development of the environment, the development of the electric vehicle industry has been strongly supported by national policies. With the continuous improvement of the energy density of vehicle power batteries and the continuous improvement of vehicle drive motor control technology, the reliability of electric vehicles has been greatly improved, and it has been more and more recognized by people. However, traditional cars have a high road occupancy rate and low utilization of interior space, which are the main reasons for urban road congestion; ordinary longitudinal two-wheeled electric vehicles (including electric bicycles and electric motorcycles) cannot meet the requirements of national motor vehicle te...
