Abstract EN
For in-wheel-motor-driven electric vehicles, the motor is installed in the wheel directly.
Tyre runout and uneven load can cause magnet gap deformation in the motor, which will produce electromagnetic forces that further influence the vehicle rollover characteristics.
To study the rollover characteristics, a verified 16-degree-of-freedom rollover dynamic model is introduced.
Next, the vehicle rollover characteristics both with and without electromagnetic force are analyzed under conditions of the Fixed Timing Fishhook steering and grade B road excitation.
The results show that the electromagnetic force has a certain effect on the load transfer and can reduce the antirollover performance of the vehicle.
Therefore, the effect of the electromagnetic force on the rollover characteristic should be considered in the vehicle design.
To this end, extensive analysis was conducted on the effect of the road level, vehicle speed, and the road adhesion coefficient on the vehicle rollover stability.
The results indicate that vehicle rollover stability worsens when the above-mentioned factors increase, the most influential factor being the road adhesion coefficient followed by vehicle speed and road level.
This paper can offer certain theory basis for the design of the in-wheel-motor-driven electric vehicles.
