Detailed Description
Reference will now be made to of the various embodiments of the invention in order to provide a basic understanding of the invention, and it is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.
Fig. 1 is a flowchart showing a method of controlling the opening/closing of the P range-related automatic parking function of the present invention.
As shown in fig. 1, the method for controlling the opening/closing of the P range-associated automatic parking function of the present invention includes the steps of:
, decision step S100, judging whether the vehicle is in a stationary state, if so, continuing the following steps;
second determination step S200: acquiring an electronic parking button signal, judging whether the electronic parking button is in a pulled-up state or not according to the electronic parking button signal, and continuing the subsequent steps if the electronic parking button is judged to be in the pulled-up state;
third determination step S300: acquiring a steering angle signal of a steering wheel and judging whether the steering angle signal of the steering wheel conforms to a preset type, wherein the steering angle signal of the steering wheel is used for a steering angle sensor;
fourth determination step S400: judging whether the gear is P gear according to the gear signal, and continuing the subsequent steps under the condition that the gear is P gear, wherein the gear signal CAN be obtained through a CAN bus;
a control step S500 of controlling the P range-associated automatic parking function to be enabled or disabled according to the determination results of the determination step S100 at the , the second determination step S200, the third determination step S300, and the fourth determination step S400;
a presentation step S500: the user is prompted to control the control result of step S300 through, for example, the dashboard of the vehicle.
The prompting step S500 is an unnecessary step, and is only for giving a clearer prompt to the driver.
At decision step S , a brake pedal signal and a wheel speed signal are obtained, from which it is determined whether the driver applies the brake and from which it is determined whether the vehicle state is stationary.
For example, the vehicle state is determined to be stationary in the case where the brake pedal sensor signal is set to 1 and the wheel speed signal is 0 or close to 0. If it is determined that the vehicle is in a stationary state, the determination is continued in step S200, otherwise, the operation returns to the initial operation, i.e., step S100 is resumed.
In the second determination step S200, the electronic parking button signal is acquired and determined according to the electronic parking button signal , the electronic parking button signal is divided into the following three states:
(1) pull-up state (lock): the button is pulled up, indicating that parking is requested;
(2) neutral state (neutral): the driver has no operating buttons; and
(3) released state (release): the button is pressed, indicating a request to release park.
In the determination step S200, it is determined whether or not the electronic parking button is in the pulled-up state (the (1) th state described above), and if it is determined that the electronic parking button is in the pulled-up state, the subsequent steps are continued, otherwise, the operation returns to the initial operation, and the step S100 is resumed.
If it is determined in the third determination step S300 that the steering wheel angle signal is an th type signal and the range signal is a prescribed change in the fourth determination step S400, controlling the P range-associated automatic parking function to be disabled in the control step S500;
if it is determined in the third determination step S300 that the steering wheel angle signal is the second type signal and the range signal is the prescribed change in the fourth determination step S400, the P range-associated automatic parking function is controlled to be enabled in the control step S500.
Specifically, the setting may be performed in the following manner:
(1) th mode:
in the case where it is judged in the third judgment step S300 that the steering angle is clockwise rotated to exceed a preset value and it is judged in the fourth judgment step S400 that the shift position signal is switched from the P range (i.e., the parking range) to the N range (i.e., the neutral range), it is judged in the third judgment step S300 that the steering angle is again counterclockwise rotated to exceed a preset value and it is judged in the fourth judgment step S400 that the shift position signal is switched from the N range to the P range, the P range-associated automatic parking function is controlled not to be enabled in the control step S500;
in the case where it is determined in the third determination step S300 that the steering angle has been counterclockwise rotated to exceed the preset value and it is determined in the fourth determination step S400 that the shift position signal has been switched from the P range to the N range, it is determined in the third determination step S300 that the steering angle has been clockwise rotated to exceed the preset value and it is determined in the fourth determination step S400 that the shift position signal has been switched from the N range to the P range, the P range-associated automatic parking function is controlled to be enabled in the control step S500.
(2) The second mode is as follows:
when the steering angle is judged to be counterclockwise rotated to exceed the preset value in the third judgment step S300 and the shift position signal is judged to be switched from the P gear to the N gear in the fourth judgment step S500, the steering angle is judged to be clockwise rotated to exceed the preset value again in the third judgment step S300 and the shift position signal is judged to be switched from the N gear to the P gear in the fourth judgment step S400, the P-gear associated automatic parking function is controlled to be disabled in the control step S500;
in the case where it is judged in the third judgment step S300 that the steering angle is clockwise rotated to exceed the preset value and it is judged in the fourth judgment step S400 that the shift position signal is switched from the P range to the N range, it is judged in the third judgment step S300 that the steering angle is further counterclockwise rotated to exceed the preset value and it is judged in the fourth judgment step S400 that the shift position signal is switched from the N range to the P range, the P range-associated automatic parking function is controlled to be enabled in the control step S500.
The angle of the preset value can be set arbitrarily, and can be set to an angle that is easier for the driver to grasp, for example, 180 degrees.
Next, with reference to fig. 2 and 3, the specific flow of two embodiments of the method for controlling the opening/closing of the P range-related automatic parking function according to the present invention will be described.
Fig. 2 is a detailed flowchart of embodiments of the control method of the P range-related automatic parking function of the present invention, fig. 2 shows an embodiment in a situation where the driver wishes to turn off the P range-related automatic parking function (i.e. to disable the P range-related automatic parking function).
As shown in fig. 2, the driver depresses the brake at step S11, and at step S12, it is determined whether the vehicle is stationary and the brake light switch is set to 1, and if the determination result is yes ("Y" in the figure), the process proceeds to step S13, and if the determination result is no ("N" in the figure), the process returns to the step S11.
In step S13, the driver presses an electronic parking button (EPB button).
In step S14, it is determined whether the electronic parking button is in the pulled-up state and whether the shift position signal is in the P range, and if it is determined that the shift position signal is in the P range ("Y" in the drawing), the process proceeds to step S15, and if it is determined that the shift position signal is not in the P range ("N" in the drawing), the process returns to the step S11.
In step S15, it is determined whether or not the steering angle is greater than 180 degrees and whether or not the shift position signal is switched from the P range to the N range is determined, and if it is determined that the shift position signal is switched from the P range ("Y" in the drawing), the routine proceeds to step S16, and if it is determined that the shift position signal is not switched ("N" in the drawing), the routine returns to the step S11.
In step S16, it is determined whether or not the steering angle is smaller than-180 degrees and whether or not the shift position signal is switched from the N range to the P range is determined, and if it is determined that the shift position signal is switched from the N range ("Y" in the drawing), the routine proceeds to step S17, and if it is determined that the shift position signal is not switched from the N range ("N" in the drawing), the routine returns to the step S11.
In step S17, the P range-related automatic parking function is disabled and the instrument panel indicates that the P range-related automatic parking function is turned off.
Thus, according to the above steps, whether the P range-associated automatic parking function is disabled (i.e., the P range-associated automatic parking function is turned off) is controlled by taking as input signals whether the driver steps on the brake, whether the electronic parking button (EPB button) is pressed, whether the driver first turns the direction to the right (steering angle greater than 180 degrees) and then turns the direction to the left (steering angle less than-180 degrees), and whether the shift range signal is switched from the P range to the N range, and the actions of switching from the N range to the P range.
Fig. 3 is a detailed flowchart of another embodiments of the method for controlling the on/off of the P range-associated automatic parking function of the present invention, fig. 3 shows an embodiment in a situation where the driver wishes to turn on the P range-associated automatic parking function (i.e., to make the P range-associated automatic parking function enabled).
As shown in fig. 3, the driver depresses the brake in step S21, determines whether the vehicle is stationary and the stop lamp switch is set to 1 in step S22, continues to step S23 if the determination result is yes ("Y" in the figure), and returns to the point before step S21 if the determination result is no ("N" in the figure).
In step S23, the driver presses an electronic parking button (EPB button).
In step S24, it is determined whether or not the electronic parking button is in the pulled-up state, and if the determination result is yes ("Y" in the figure), the process proceeds to step S25, and if the determination result is no ("N" in the figure), the process returns to the state before step S21.
In step S25, it is determined whether or not the steering angle is smaller than-180 degrees and whether or not the shift position signal is switched from the P range to the N range is determined, and if it is determined that the shift position signal is switched from the P range ("Y" in the drawing), the routine proceeds to step S26, and if it is determined that the shift position signal is not switched ("N" in the drawing), the routine returns to the step S11.
In step S26, it is determined whether or not the steering angle is greater than 180 degrees and whether or not the shift position signal is switched from the N range to the P range is determined, and if it is determined that the shift position signal is switched from the N range ("Y" in the drawing), the routine proceeds to step S27, and if it is determined that the shift position signal is not switched from the N range ("N" in the drawing), the routine returns to the step S21.
In step S27, the P range-related automatic parking function is enabled and the instrument panel indicates that the P range-related automatic parking function is on.
Thus, according to the above steps, whether the P range-associated automatic parking function is enabled (i.e., the P range-associated automatic parking function is turned on) is controlled by taking as input signals whether the driver steps on the brake, whether the electronic parking button (EPB button) is pressed, whether the driver first turns the direction to the left (steering angle less than-180 degrees) and then turns the direction to the right (steering angle greater than 180 degrees), and whether the shift range signal is switched from the P range to the N range, and these actions when switching from the N range to the P range.
