Embodiment 1
[0044] Such as figure 1 As shown, the electric field truck described in this embodiment includes 4 wheels, 2 brake mechanisms and 2 steering mechanisms, and its distributed drive system is: each wheel is independently driven by a brushless DC in-wheel motor , each braking mechanism is driven by a DC motor for braking, and each steering mechanism is driven by a DC motor for steering. The main controller of the electric field truck is an embedded microcontroller based on the ARM core. controller. The model of the main controller used in this embodiment is STM32F103RCT6. The main controller performs calculation according to the steering signal and speed signal input from the outside, and then controls the speed of four brushless DC wheel hub motors through the brushless DC motor driver, and controls two steering DC motors and two DC motors through the DC motor driver. DC motor for braking. Using the main controller of the above structure to control 8 motors in real time at the...
