Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a control method for a hidden door handle according to an embodiment of the present invention, which is applicable to a situation of controlling a hidden door handle of a vehicle, and the method can be executed by a control device of the hidden door handle, as shown in fig. 1, and the method specifically includes the following steps:
and step 110, when the control signal is received, determining the current state of the hidden door handle.
The control signal may be generated by a user triggering a control signal generation module, and the control signal generation module may be a key or a door handle switch. The state in which the hidden door handle is currently located may be a sprung-open state or a retracted state.
In step 120, a control mode is determined according to the current state of the hidden door handle.
The control mode may include a pop-up mode and a retraction mode. Specifically, the process of determining the control mode according to the current state of the hidden door handle may be: if the current state of the hidden door handle is the spring-open state, the hidden door handle is controlled to be in a retraction mode; if the current state of the hidden door handle is the retraction state, the control mode is the pop-up mode.
And step 130, driving the hidden door handle to act according to the control mode.
In this embodiment, when the control mode is the pop-up mode, the process of driving the hidden door handle according to the control mode may be: driving the hidden door handle to pop open by using a Pulse Width Modulation (PWM) signal with a duty ratio as a first set value within a first time period; if the flick limit switch is identified, the hidden door handle is driven to flick by the PWM signal with the duty ratio as a second set value within a second time period; and driving the hidden door handle to pop open by using the PWM signal with the duty ratio as a third set value in a third time period.
Wherein the first time period may be 200ms, the first set value may be 60%, the second time period may be 1700ms, the second set value may be 85%, the third time period may be 500ms, and the third set value may be 55%. For example, fig. 2 is an exemplary diagram of the pop-up mode, and as shown in fig. 2, when the control mode is the pop-up mode, the vehicle door controller drives the hidden door handle with a PWM waveform with a duty ratio of 60% between 0ms and 200ms, so as to realize the slow start of the door handle; between 200ms and 1900ms (1700 ms in total), the door controller drives the hidden door handle with a PWM waveform with a duty ratio of 85%, namely, the door handle is impacted by larger force to be bounced open; between 1900 and 2400ms (500 ms in total), the door controller drives the door handle with a PWM waveform with a duty ratio of 55% so as to facilitate the soft stop of the door handle.
Optionally, after the hidden door handle is driven by the pulse width modulation PWM signal with the duty ratio as the first set value within the first time period, the method further includes: if the flick limit switch is not identified, the hidden door handle is driven to flick by the PWM signal with the duty ratio as a second set value within a second time period; driving the hidden door handle to pop open by a PWM signal with the duty ratio as a fourth set value within a fourth time period; judging whether the flick limit switch is identified or not, and waiting for a fifth time period if the flick limit switch is not identified; driving the hidden door handle to retract by using a PWM signal with the duty ratio as a fourth set value; if the withdrawing limit switch is detected within the sixth time length or the withdrawing limit switch is not detected beyond the sixth time length, continuing waiting for the fifth time length; driving the hidden door handle to pop open by using a PWM signal with the duty ratio as a fourth set value; if the flick limit switch is detected within the sixth time, the hidden door handle flicks successfully; if the bouncing limit switch is not detected after the sixth time and the cycle number does not reach the set value, the operation of waiting for the fifth time and driving the hidden door handle to retract by the PWM signal with the duty ratio being the fourth set value is returned until the hidden door handle is successfully bounced open.
Wherein the fourth time period may be 500ms, and the fourth setting value may be 100%. The fifth time period may be 1s, the sixth time period may be 2.4s, and the set value may be set 4 times. Specifically, in the pop-up mode, between 0-200ms, the door controller drives the door handle switch to pop-up with a PWM waveform having a duty cycle of 60%. 200-1900ms (1700 ms in total), the door controller does not recognize the flick limit switch signal of the hidden door handle, and the door handle is driven by the PWM waveform with the duty ratio of 85 percent, so that the impact is carried out by larger force; if the flick limit switch signal is not recognized, the vehicle door controller drives the hidden door handle with the duty ratio of 100% PWM waveform at 1900-2400ms, and judges whether the flick limit switch signal exists again. If not, the hidden door handle is driven to retract by the PWM signal with the duty ratio of 100% after waiting for 1 s. And if the withdrawing limit switch is detected within 2.4s or the withdrawing limit switch is not detected for more than 2.4s, waiting for 1s, and driving the hidden door handle to pop open by using a PWM signal with the duty ratio of 100%. If the flick limit switch is detected within 2.4s, the hidden door handle flicks successfully. If the bouncing limit switch is not detected for more than 2.4s and the cycle number does not reach the set value, the operation of waiting for 1s is returned, and the PWM signal with the duty ratio of 100% drives the hidden door handle to retract until the hidden door handle is successfully bounced.
Optionally, the method further includes: and if the bounce-off limit switch is not detected in the sixth time and the cycle number reaches the set value, stopping driving the hidden door handle for the seventh time. And when the control signal is received, returning to execute the operation of driving the hidden door handle to pop open by the PWM signal with the duty ratio as the first set value in the first time period.
Wherein the seventh time period may be 5 s. When the number of cycles reaches the set value and the flick of the limit switch is not detected yet, the hidden door handle is stopped from being driven within 5s and no signal is responded within 5 s. After 5s, when the control information is received again, the entire flow of the pop-up mode is executed again.
In this embodiment, when the control mode is the retraction mode, the process of driving the hidden door handle according to the control mode may be: driving the hidden door handle to retract by a PWM signal with the duty ratio as an eighth set value within an eighth time period; and driving the hidden door handle to retract by a PWM signal with a ninth set value of the duty ratio in a ninth time period.
Wherein the eighth time period may be 1900ms, the eighth setting may be 65%, the ninth time period may be 500ms, and the ninth setting may be 35%. Exemplarily, fig. 3 is an exemplary diagram of a retraction mode of the present embodiment, as shown in fig. 3, in the retraction mode, between 0ms and 1900ms, the door controller drives the hidden door handle to retract with a PWM waveform having a duty ratio of 65%; and between 1900 and 2400ms (500 ms in total), the door controller drives the door handle to retract by using a PWM (pulse-width modulation) waveform with the duty ratio of 35%, so that the retracting force is reduced, and the door handle is convenient to stop softly.
Optionally, the method further comprises the following steps: when the control signal is received and the hidden door handle is in the spring-open state; and if the human hand is detected to be in the set area, stopping driving the hidden door handle to retract. So as to prevent hands from being clamped.
