Problems solved by technology

However, for cars that are not equipped with the anti-pinch function of the windows, it is necessary to rewire or replace the computer-controlled window lifters for later installation, which is costly and the body wiring harness will become complicated, which is not conducive to the lightness of the car.

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0020] Such as figure 1 As shown, the present invention provides a vehicle window anti-pinch system based on the OBD-II interface, including: multiple clients and a server.

[0021] Each client includes: a lifting mechanism, a control mechanism, an OBD-II interface, and a display; the lifting mechanism includes a window motor and a current detection device that drives the window to move up and down, and the current detection device is electrically connected to the window motor. To detect the current value of the window motor, a wireless transmitting device is integrated on the current detecting device; the control mechanism includes: a single-chip microcomputer and a wireless receiving device, the single-chip microcomputer is connected to the wireless receiving device, and th...

Abstract

The invention discloses a car window anti-pinch system based on OBD-II interfaces. The car window anti-pinch system comprises a plurality of client sides. Each client side comprises an ascending mechanism, a control mechanism, one OBD-II interface and a displayer. The control mechanisms are connected with a car control device through the OBD-II interfaces. Current detection devices detect current values of a car window motor in real time and send the current values to the control mechanisms. The control mechanisms judge whether a person is pinched by a car window when the car window ascends through the current values of the car window motor. According to the design, on the basis that an original car circuit is not damaged, the car window anti-pinch function is provided for a car without the car window anti-pinch function, and the defects that a car window anti-pinch system configured on a car production enterprise is high in price and can not be conveniently popularized are overcome; meanwhile, intelligent monitoring and management of the current values of the car window motor are achieved, and the car window anti-pinch system is more intelligent and user-friendly.

Description

technical field [0001] The invention relates to a vehicle window anti-pinch system based on an OBD-II interface. Background technique [0002] In order to increase the safety and comfort of the car, most cars are now equipped with electric windows. The electric window uses the electric motor to drive the window regulator so that the window can be automatically lifted up and down, which greatly facilitates the use of drivers and passengers. However, the electric window does not have a smart stop function. If the operator is not careful, he may be injured. There are quite a lot of accidents caused by electric windows every year. Therefore, for safety reasons, many mid-to-high-end cars are now equipped with electric anti-pinch window lifters (Anti-Pinch Window Lifter, APWL). Europe and the United States have successively legislated to determine APWL as the basic configuration of automobiles in order to improve driving safety and humanization. Our government is also actively ...
