Embodiment 1

[0020] figure 1 It is a functional block diagram of a vehicle speed self-calibration device provided by an embodiment of the present invention, such as figure 1 As shown, the vehicle speed self-calibration device provided in this embodiment is used to calibrate the vehicle speed of the target device. The target device is provided with wheels and motors for controlling the rotation of the wheels. The vehicle speed self-calibration device includes a classification test unit 110 and a speed regulation unit 120 .

[0021] When the target device is driving, when the motor speed is constant, when the target device passes through the ground of different materials, due to the different friction between the wheels and the ground of different materials, the driving speed will be different, such as passing through cement. The speed is faster on the ground, and the speed is slower when passing the carpet. Therefore, the classification test unit 110 first classifies the ground environment...

Embodiment 2

[0036] figure 2 is a functional block diagram of a smart device provided by an embodiment of the present invention, such as figure 2 As shown, the smart device 200 provided in this embodiment is provided with a wheel 210 and a motor 220 for controlling the rotation of the wheel 210, and the smart device 200 also includes the vehicle speed self-calibration device 230 in the first embodiment above. The smart device 200 in this embodiment may be a smart car, or other devices such as a smart robot.

[0037] The vehicle speed self-calibration device 230 can be realized by executing relevant instructions through the main control chip of the smart device. The vehicle speed self-calibration device 230 can automatically adjust the PWM waveform output to the motor according to different ground environments, and calibrate the vehicle speed of the smart device 200, so that the smart device can For different ground environments, perform motion tasks at a uniform speed to meet the needs ...

Embodiment 3

[0039] image 3 It is a flow chart of a vehicle speed self-calibration method provided by an embodiment of the present invention, such as image 3 As shown, the vehicle speed self-calibration method provided in this embodiment is used to calibrate the vehicle speed of the target device. The target device is provided with wheels and motors that control the rotation of the wheels. The vehicle speed self-calibration method in this embodiment includes:

[0040] Step S310: Divide the ground environment into several categories according to the friction between the wheels and the ground. Due to the different friction between the wheels and the ground of different materials, even if the control signals output to the motor are the same, the speed of the target equipment will be different. In order to adjust the speed of the target equipment according to different ground environments, the ground should be first Environments are divided into several categories. The target equipment can...

Abstract

The present invention discloses a speed self calibration method and device and an intelligent device. The speed self calibration method is configured to calibrate the speed of a target device which is provided with wheels and a motor controlling the rotation of the wheels. The method comprises: dividing a plurality of types of ground environments according to the conditions of the friction of the wheels and the ground; monitoring the type of the ground environment where in the target device is located in real time; sending corresponding control signals to the motor controlling the rotation of the wheels according to the type of the ground environment where in the target device is located to allow the target device to drive in a preset speed so as to allow the target device to regulate the motion speed itself according to different grounds.
