[0013] As Figure 1As shown, a multifunctional electronic gyroscope device assembly for electric vehicles includes a display screen 1, a digital compass module 2, an electronic gyroscope accelerometer / inclination sensing module 3, a slope / latitude / altitude module 4, an MCU module 5, a CAN communication module, and a peripheral auxiliary circuit,

[0014] The digital compass module 2 detects the direction in which it is located and sends angle value information indicated by the digital compass to the MCU module 5. The electronic gyroscope accelerometer / inclination sensing module 3 detects the acceleration value of the vehicle during riding and the angle value of the vehicle when it is bent during riding and sends the values to the MCU module 5. The slope / latitude / altitude module 4 detects the latitude and altitude in which it is located and sends latitude information and altitude information to the MCU module 5. The MCU module 5 receives information from the digital compass module 1, the electronic gyroscope accelerometer / inclination sensing module 2, and the slope / latitude / altitude module 3, digitizes the information, and displays it on the display screen 1. The display screen 1 receives information from the MCU module 5 and displays the angle value indicated by the digital compass, the acceleration value of the vehicle during riding, the angle value of the vehicle when it is bent during riding, and the slope / latitude / altitude of the road.

[0015] The digital compass module 2 uses a three-axis digital compass sensor HMC5883L as the main sensor, is connected to the MCU module 5 through an I2C interface, and then transmits data collected by the sensor to the MCU module 5 through an I2C protocol. The MCU module 5 sends the data to the display screen 1 for display after processing the data through a corresponding algorithm.

[0016] The electronic gyroscope accelerometer / inclination sensing module 3 uses an ADXL203 chip as the main sensor, is connected to the MCU module 5 with the cooperation of a peripheral driving circuit, and the MCU calculates the acceleration of the vehicle during riding through data output by the module. The MCU module 5 calculates the inclination angle of the vehicle in the X and Z axes through the algorithm based on the data collected by the sensor chip and transmitted to the MCU module 5.

When the inclination angle of the vehicle is <60±5° in the normal riding state of the vehicle, the electronic gyroscope outputs no dump fault to the motor controller through the CAN module. When the vehicle rolls over >65±5°, the electronic gyroscope outputs a dump fault to the motor controller through the CAN module after a time delay of 2s. The fault is continuously sent to the motor controller, and the fault can be cleared only when the vehicle returns to the normal angle, the inclination angle is <60±5°, and the power is reconnected.
