Fig. 1 is a schematic view of a vehicle of an embodiment of the invention. As shown in fig. 1, the vehicle of the embodiment of the invention includes a vehicle frame 1, wheels 2, and a brake system.
Fig. 2 is a schematic view of a brake system of the first embodiment of the present invention. Referring to fig. 1 and 2, the brake system according to the embodiment of the present invention includes a lever 31 (including 31a and 31b), a detecting part 32, a control part 33, and a first brake part 34. The detecting component 32 is configured to output a detection signal corresponding to the rotation angle of the brake lever 31. The control unit 33 is configured to determine a change rate of the detection signal according to the detection signal, and output a brake signal corresponding to the change rate. The first brake component 34 is configured to generate a corresponding first braking force according to the braking signal.
In this embodiment, as shown in fig. 3, the brake lever 31 is rotatably connected to the brake holder 35, and the brake lever is movable between a position S1 and a position S2. A reset element (not shown in the figures) is arranged between the brake lever 31 and the brake holder 35, and specifically, when the brake lever 31 is not subjected to an external force, the brake lever 31 is reset by the reset element, i.e., at the position S1, and when pressed by a force, the brake lever can be moved to the position S2. Thereby, the brake lever 31 can be moved between the position S1 and the position S2.
In the present embodiment, the detecting component 32 is used for outputting a corresponding detection signal according to the rotation angle of the brake lever 31. Specifically, when the brake lever 31 is moved between the position S1 and the position S2, the detecting member 32 outputs the corresponding detection signal U when the brake lever is at a different position.
In some embodiments, the detection component 32 may be implemented by a hall element. Specifically, a magnetic element may be disposed on the brake lever 31, and when the brake lever 31 rotates, the position of the magnetic element is driven to change, so that the magnetic field at the position of the hall element changes, and then the corresponding detection signal U is output.
In the present embodiment, the control unit 33 receives the detection signal U, determines the rate of change K of the detection signal from the detection signal, and outputs the brake signal B corresponding to the rate of change K.
Further, the control section is configured to determine a rate of change of the detection signal from the detection signal at a predetermined cycle.
Further, the control component is used for determining the change rate of the detection signal of the current period according to the detection signal and determining the brake signal of the next period according to the change rate of the detection signal of the current period.
Further, the control unit 33 receives a detection signal U, from which the rate of change of the detection signal is determined at the end of each cycle.
Further, in each cycle, the control part 33 outputs the brake signal B of the current cycle according to the change rate of the detection signal of the previous cycle. That is, in the (i + 1) th cycle, the corresponding brake signal B is output according to the change rate of the (i) th cyclei+1。
Further, the change rate is an amount of change in the detection signal per unit time. Wherein, the variable quantity of the detection signal is used for representing the rotation angle of the brake lever.
Specifically, the calculation formula of the change rate is:
wherein, KiIndicating the rate of change, U, of the ith cyclei1Value, U, of the detection signal representing the start of the ith cyclei2The value of the detection signal at the end of the i-th cycle is shown, and T shows the cycle.
Thus, at the end of each cycle, the rate of change of the detection signal within that cycle can be determined for outputting the brake signal in the next cycle.
In an alternative implementation, the control unit 33 determines the brake signal corresponding to the rate of change according to a predetermined function, which is the correspondence of the rate of change to the brake signal. Specifically, assuming that the predetermined function is B ═ f (K), after the rate of change K of the detection signal is acquired, the corresponding brake signal B can be obtained according to the predetermined function.
In another optional implementation manner, the control component determines the brake signal corresponding to the change rate according to a predetermined mapping relationship, wherein the mapping relationship is a correspondence relationship between a change rate interval and the brake signal. Specifically, FIG. 4 is an example of a bit-mapped relationship, where Kr1Represents the minimum rate of change and can be 0 or a value greater than 0, KrmIndicating the maximum rate of change. Presetting a pair of a change rate interval and a brake signalThe relationship is used. And after the change rate K of the detection signal is obtained, determining the interval where the change rate is located, and obtaining the brake signal B corresponding to the located interval.
Thus, the control unit can obtain the corresponding brake signal.
Further, for the determination of the period, it may be implemented in various existing manners, and the following two examples are given in the embodiment of the present invention:
as an example, when the vehicle is turned on, the control part 33 starts timing. Specifically, the unlock time of the vehicle or the time of turning on the battery may be determined as a vehicle turn-on time, and when the vehicle is turned on, timing is started, and according to a predetermined period (for example, 1ms), at the end of each period, the change rate of the detection signal in the period is calculated. More specifically, as shown in FIG. 5, tiTo ti+1Indicating a cycle, i is 0, 1, 2, … …, and during the first cycle (time period t0-t 1), the output brake signal is a default value, i.e., 0. Assuming that the vehicle is turned on at time t0, the value of the detection signal U1 is an initial value and does not change during the time period t0-t1 (the first period), and is always kept at U1, that is, the calculated change rate is 0 at time t1, and correspondingly, the output brake signal B2 is 0 during the time period t1-t2 (the second period). In the time period t1-t2 (the second cycle), the value of the detection signal is changed from U1 to U2, that is, the calculated change rate at the time t2 is not 0, the control unit calculates the change rate and determines that the corresponding brake signal is B3, and correspondingly, in the time period t2-t3 (the third cycle), the output brake signal is B3. By analogy, in the time period from t5 to t6 (the sixth period), the value of the detection signal is changed from U5 to U6, that is, the change rate calculated at the time t6 is not 0, the control unit calculates the change rate and determines that the corresponding brake signal is B7, and correspondingly, in the time period from t6 to t7 (the seventh period), the output brake signal is B7. Thus, at the end of the i-th cycle, the control unit calculates the rate of change of the detection signal in the i-th cycle, and obtains a corresponding brake signal, and at the i + 1-th cycle, controls the first brake unit 34 based on the obtained brake signal.
Example two, the timing is started when the detection signal changes. Specifically, it is assumed that the detection signal output by the control part gradually increases when the brake lever is moved from the position S1 to the position S2. A comparator may be provided in the control unit 33, with a non-inverting input connected to the output of the detection unit 32 and an inverting input to which a reference signal is input, the reference signal being the initial value (or slightly greater than the initial value) of the detection signal, wherein the initial value is the value of the detection signal output by the detection unit when the brake lever is at the position S1. When the position of the lever is at S1, the detection signal output by the comparator is 0, and the control part 33 does not perform the braking operation; when the lever is pressed by the pressing phase position S2, the detection signal output from the comparator is 1, and the control unit 33 starts timing. More specifically, as shown in fig. 6, during the time period t0-t1, the detection signal output by the detection unit is U1, at this time, the output signal C of the comparator is 0, the control unit is not clocked, no braking operation is performed, and the output braking signal B1 is 0. At time t1, the brake lever is pressed, the detection signal output by the detection part is greater than U1, the signal C output by the comparator is 1, the control part starts timing, the first period is t1 to t2, and the brake signal B1 is 0. At time t2, the first cycle is timed out, the control calculates the rate of change and determines the brake signal to be B2 based on the rate of change. the second period from t2 to t3 is B2. At time t3, the second cycle is timed out and the control unit calculates the rate of change of the second cycle for outputting a corresponding brake signal in the third cycle. Thus, at the end of the i-th cycle, the control unit calculates the rate of change of the detection signal in the i-th cycle, and obtains a corresponding brake signal, and at the i + 1-th cycle, controls the first brake unit 34 based on the obtained brake signal.
In the present embodiment, the first brake component 34 generates a corresponding first braking force according to the braking signal.
In some embodiments, the first braking component 34 is an electric motor, wherein the braking signal is used to control the electric motor to apply a reverse driving force, thereby achieving a braking effect. Specifically, when the control part detects that the change rate is not 0, the power output of the motor is stopped firstly, a corresponding current parameter is determined according to the change rate, and the motor is controlled to generate a corresponding electromagnetic braking torque according to the current parameter.
In some embodiments, the first brake component 34 may also be an electronic brake, such as an electronic band-type brake, wherein the brake signal is used to control the electronic brake to generate a force for preventing the wheel from rotating, so as to achieve a braking effect.
According to the embodiment of the invention, the detection part outputs the detection signal corresponding to the rotation angle of the brake lever, the control part determines the change rate of the detection signal according to the detection signal, and then outputs the corresponding brake signal according to the change rate so as to control the first brake part to generate the first brake force. Therefore, the strength of the braking intention of the user can be determined through the change rate of the braking signal, and the riding safety of the user is improved.
Fig. 7 is a schematic view of a brake system of a second embodiment of the present invention. As shown in fig. 7, the brake system of the embodiment of the present invention includes a lever 31, a detecting part 32, a control part 33, a first brake part 34, a second brake part 36, and a brake cable 37. The working principle of the detecting component 32, the controlling component 33 and the first braking component 34 can be as shown in fig. 2-5, and will not be described herein.
In the present embodiment, the brake lever 31 is connected to the second brake component 36 through the brake cable 37, and referring to fig. 3, when the brake lever 31 moves between the position S1 and the position S2, the brake cable is stretched, so as to stretch the second brake component 36, and the second brake component 36 generates a second braking force for preventing the wheel from rotating, so as to brake the vehicle.
Further, the second brake component may be implemented by various existing vehicle brake components, such as a band-type brake, a caliper, and the like.
From this, brake the vehicle through first brake part and second brake part simultaneously, can realize better braking effect, simultaneously, can reduce the loss of arbitrary one brake part, moreover, when arbitrary one brake part damaged, can also realize the braking through another brake part, improve the safety of riding.
According to the embodiment of the invention, the detection part outputs the detection signal corresponding to the rotation angle of the brake lever, the control part determines the change rate of the detection signal according to the detection signal, and then outputs the corresponding brake signal according to the change rate so as to control the first brake part to generate the first brake force. Therefore, the strength of the braking intention of the user can be determined through the change rate of the braking signal, and the riding safety of the user is improved.
