In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description of the wheel braking method, the wheel braking system and the automobile will be made with reference to the accompanying drawings and the specific embodiments.
The invention provides a wheel braking method, as shown in fig. 1, which is a flow chart of the wheel braking method of the invention, wherein the method comprises the following steps:
s1, the control unit receives a brake electronic signal sent by the brake electronic pedal; the brake electronic signal has a specific numerical value, generally, an output numerical value is determined according to the treading depth or the treading speed of the brake electronic pedal, and the numerical value is larger when the brake electronic pedal is treaded deeper, or the numerical value is larger when the treading speed is faster, so that the acceleration corresponding to the brake is larger; the brake electronic signal is an electric signal, so long as the form of the electric signal can be output.
S2, the control unit judges whether the value of the brake electronic signal is within a wheel rotation preset range; the wheel rotation preset range is a preset fixed value set and is matched with a brake electronic signal sent by a brake electronic pedal, and the value of the brake electronic signal and the boundary value of the wheel rotation preset range can be compared with each other.
And S3, if the value of the brake electronic signal is within the preset range of the wheel rotation, the control unit sends a steering signal to the rotary actuator.
S4, driving wheels in the same row to steer by a rotary actuator, wherein the wheels on the two sides of the vehicle body arranged in the same row rotate symmetrically by equal angles; the rotation refers to that the wheels rotate around the vertical rotating shaft, namely the wheels originally run in the forward direction, and the wheels on the two sides of the same row rotate in the same direction by equal angles during turning, so that the vehicle body is steered; when the wheel braking process is executed, the wheels on the two sides of the same row rotate in opposite directions by equal angles, namely one wheel rotates clockwise and the other wheel rotates anticlockwise, as shown in fig. 2A, the wheel braking process is a schematic diagram of normal running of the vehicle, fig. 2B is a schematic diagram of a first state of the vehicle executing wheel braking, fig. 2C is a schematic diagram of a second state of the vehicle executing wheel braking, and fig. 2D is a schematic diagram of a third state of the vehicle executing wheel braking; in the process of braking the wheel, the inertia of the wheel does not only face forwards any more, but also has a lateral component, so that the sum of the inertia superposition of the vehicle body and the wheel is reduced; the rotational inertia of the wheels has a rearward component as shown in fig. 2C, and is fully rearward as shown in fig. 2D, both of which counteract a portion of the forward inertia of the vehicle body, and the vehicle is stopped more quickly by friction of the wheels against the ground.
Step S2, the control unit determines whether the value of the brake electronic signal is within a preset range of the wheel rotation, if yes, the method further includes the following steps:

if not, directly controlling the brake pad and the brake disc to rub and brake with each other through a brake motor according to the brake electronic signal; the value of the brake electronic signal determines the pressure between the brake pads and the brake disc. When the current speed of a motor vehicle is within the speed range and the value of the brake electronic signal is within the preset range of the wheel rotation, the brake can be realized by adopting the friction between the traditional brake pad and the brake disc, the brake force is determined according to the brake electronic signal value, the larger the brake electronic signal value is, the larger the friction brake force is, and the larger the speed of the speed reduction during the brake is.

If the distance from the obstacle is not less than the safe distance, normal running is kept, and if the distance from the obstacle is less than the safe distance and the vehicle speed is not within the preset vehicle speed range, automatic braking can be achieved through a conventional mode that a brake block and a brake disc rub against each other.
Step S2, the control unit judges whether the value of the brake electronic signal is in the wheel rotation preset range, if yes, the method further comprises the following steps:
s22, detecting the wheel angle and judging whether the wheel is in a straight-going state;
if so, the control unit sends a steering signal to the rotation actuator;
if not, the brake is braked by mutual friction of the brake pad and the brake disc; and determining the pressure between the brake pad and the brake disc according to the value of the brake electronic signal.
Through the steps, when the trampling degree of the brake electronic pedal is judged, the running state of the vehicle is also required to be judged, the reverse braking process of the wheel is executed only when the vehicle normally runs straight, and if the wheel is steering, the brake can be braked in a mode of mutual friction between a traditional brake block and a brake disc, so that the rollover accident of the vehicle is avoided.
