Problems solved by technology

[0003] In the prior art, the software strategy for judging the closed state of the back door of the car is to simultaneously collect Hall value information and door lock signal information to judge the state of the back door, which is prone to misjudgment. When the accumulated opening value is reached, the vehicle instrument shows that the back door is open, causing trouble to the user

Embodiment Construction

[0015] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0016] In the prior art, when the door lock is in the locked state, due to the accumulation of the Hall value, the back door control unit ECU may think that the back door is open at this time, resulting in a wrong judgment of the back door state. This application improves the control method on the basis of the existing acquisition unit of the electric back door of the automobile, so as to overcome the possible misjudgment and make the judgment more accurate.

[0017] First of all, the hardware system that the back door control judgment method depends on includes the pole Hall unit of the electric back door, which is used to collect the Hall value of the pole; the door lock signal unit is used to collect the state of the door lock of the back door, and the state of the door lock includes The...

Abstract

The invention discloses a control and judgment method of a car back door state. The control and judgment method comprises the steps that whether a back door lock is in a closed state or in an opened state is judged through a door lock signal unit; and if the back door lock is in the closed state, at the moment, a back door ECU conducts clear operation through a Hall value collected by a stay rod Hall unit, data collected by the stay rod Hall unit are cleared, and it is judged that a back door is in the closed state at the moment. The control and judgment method has the advantages that the phenomena of misjudgment and false alarm which are generated by accumulation of the stay rod Hall value due to vibration when a car back door is in a closed state in the prior art are avoided, state judgment of the back door is more accurate, and a car electric back door control system is more humanized.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for controlling and judging the state of a rear door of an automobile. Background technique [0002] In order to meet the convenient, fast and personalized customer needs, the functions of automobiles and vehicles are becoming more and more complex. The electric back door function has become a highlight of high-end high-end cars. At the same time, in order to improve the user experience and expand the competitiveness of products in the market, the safety and stability of the automobile back door control system have been paid more and more attention. [0003] In the prior art, the software strategy for judging the closed state of the back door of the car is to simultaneously collect Hall value information and door lock signal information to judge the state of the back door, which is prone to misjudgment. When the accumulated opening value is reached, the vehicle ins...
