Description
Technical Field
The invention relates to the technical field of vehicle door control, in particular to a control method comprising a door lock mechanism, which is used for controlling the electrically controlled opening of a vehicle door.
Background
At present, when the automobile door is opened, an outer door handle or an inner door handle needs to be pulled, pulling force is transmitted to a door opening mechanism through a pull rope, and the door opening mechanism is pulled to rotate, so that the automobile door can be pulled or pushed to be opened. The design mode of opening the door can realize the opening of the vehicle door only by pulling the handle or the handle with force by a user, and is not friendly to personnel with small hand strength; when the door is opened from the inside of the vehicle, the door needs to be pulled inwards firstly and then pushed outwards to open the door, so that the operation is inconvenient.
Disclosure of Invention
The invention provides a vehicle electric control door opening control method and system, which integrate the unlocking state of the current door lock mechanism by identifying the door opening intention of a user and adopt an electric control mode to control the rotation of the door opening mechanism, so that the user can directly pull or push a vehicle door to open with smaller force, and the problems of difficult door opening and inconvenient operation are solved.
The technical scheme of the invention is as follows:
a vehicle electric control door opening control method comprises the steps of firstly identifying that a user has door opening intention, then comprehensively judging an unlocking state signal of a door lock, if a vehicle door is unlocked, controlling a pawl motor of a door opening mechanism to rotate anticlockwise, and judging whether the vehicle door is in a slightly-opened state or not; and starting timing after the door opening mechanism is in a slightly opened state, and controlling the door opening mechanism pawl motor to rotate clockwise to return after the time of T1 is exceeded, and controlling the door opening mechanism pawl motor to rotate clockwise to return if the door opening mechanism is still in the slightly opened state within the time of T1 and immediately controlling the door opening mechanism pawl motor to rotate clockwise to return if the door opening mechanism is in a fully opened state within the time of T1.
The method specifically comprises the following steps:
And 2, controlling a pawl motor module of the door opening mechanism to carry out motor driving, controlling the motor to rotate anticlockwise, and driving the pawl to rotate anticlockwise by the rotation of the motor to separate from the ratchet wheel.
And step 4, controlling the pawl motor to rotate clockwise, driving the pawl to rotate clockwise to return and reporting an error.
Step 5, starting timing when the vehicle door is in a slightly opened state, and judging whether a signal that the vehicle door is in a fully opened state is received within the time T1; if the vehicle door is in the full-open state, turning to the step 6; and if the vehicle door is not in the full-open state, the step 7 is carried out.
And 6, controlling a motor module of the door opening mechanism to carry out motor driving, and driving a pawl motor to rotate clockwise to return.
Step 7, judging whether the time exceeds T1, and if the time does not exceed T1, turning to step 5; if the time T1 is exceeded, go to step 8.
And 8, controlling a motor module of the door opening mechanism to drive a motor and controlling a pawl motor to return when the time exceeds T1.

An embodiment of a specific control of the present invention is shown in fig. 5, and the detailed steps are as follows:
step S501, the door opening intention recognition module outside the vehicle or the door opening intention recognition module inside the vehicle detects whether a door opening demand signal outside the vehicle or inside the vehicle exists through the door opening intention detection sensor.
In step S502, the door unlock state detection module determines the door unlock state through the unlock state detection sensor.
Step S503, the door opening control module judges whether a door opening requirement is received or not and the unlocking state of the vehicle door is received; when the door opening requirement is received and the vehicle door is in the unlocking state, the step S504 is executed; and when the door opening requirement is not received or the vehicle door is not in the unlocking state, continuously judging the door opening requirement and the unlocking state.
And step S504, receiving a door opening requirement and receiving that the vehicle door is in an unlocking state, controlling a door opening control module to control a door opening mechanism pawl motor module to carry out motor driving, controlling a motor to rotate anticlockwise, and driving a pawl to rotate anticlockwise to be separated from a ratchet wheel by the rotation of the motor.
And step S505, the door slight opening detection module detects the slight opening state of the vehicle door through the door slight opening detection sensor.
Step S506, after the pawl motor is driven, judging whether the vehicle door is in a slightly opened state; if the vehicle door is not in the slightly opened state, the step S507 is carried out; if the door is in the ajar state, the process goes to step S508.
And step S507, after the pawl motor is driven, if the vehicle door is not in a slightly opened state, controlling the pawl motor to rotate clockwise, and driving the pawl to rotate clockwise to return to the original position by the rotation of the motor, and reporting an error.
Step S508, after the pawl motor is driven, the door is in a slightly opened state, and the door opening control module starts timing after receiving that the door is in the slightly opened state, and then the process goes to step S510.
In step S509, the door full-open detection module detects the full-open state of the vehicle door by the door full-open detection sensor.
Step S510, judging whether a signal that the vehicle door is in a fully open state and sent by a door fully open detection module is received within T1 time; if the vehicle door is in the full-open state, turning to the step S511; if the door is not in the fully opened state, the process goes to step S512.
And step S511, in the time of T1, when a door fully-open state signal sent by the door fully-open detection module is received, the door opening mechanism motor module is controlled to drive the motor, and the pawl motor is driven to rotate clockwise to return.
Step S512, if the vehicle door is not in the full open state, judging whether the time exceeds T1; if the time does not exceed the time T1, go to step S510; if the time period exceeds T1, the process goes to step S513.
And step S513, if the time exceeds T1 and the vehicle door full-open state signal sent by the door full-open detection module is still not in the full-open state, controlling the door opening mechanism motor module to drive the motor and controlling the pawl motor to return.
Namely, when the vehicle door is not fully opened, the pawl needs to return when waiting for full opening or overtime, so that the half-locking condition is avoided when the user slowly opens the door or stops on an uphill slope to open the door with difficulty; and the full open state can return immediately, so that the automobile door is closed without worrying about the half lock condition after the pawl motor returns, the automobile door lock catch returns to the inner side of the ratchet wheel to drive the ratchet wheel to rotate clockwise to the full close position, the tail end of the pawl clamps the ratchet wheel, and the automobile door is normally closed.
