Problems solved by technology

[0003] The purpose of the present invention is to provide an anti-pinch car sunroof control system, which is used to solve the problem of pinching the human body when the car sunroof exists. The present invention detects whether there is a foreign object in the covered area of ​​the sunroof through radar detection technology, and if there is, it will automatically return it. It will be closed if no foreign matter is detected, so that the effect of not touching the human body and anti-clamping can be achieved, which fundamentally eliminates the problem of the skylight pinching the human body

Embodiment 1

[0025] combined with figure 1 As shown, a kind of anti-trap automobile sunroof control system comprises power supply 1, switch 2, controller 3, relay 4 and motor 5, and described switch 2 is connected with described power supply 1, controller 3 and relay 4 respectively, and described The relay 4 is connected with the controller 3 and the motor 5 respectively, and the controller 3 includes an automobile computer ECU and a radar receiver, and the radar receiver is connected with a plurality of radars 9 .

[0026] working principle:

[0027] When the button to close the sunroof is pressed, the radar 9 is energized to send out radar waves, which are reflected back after hitting the opposite side of the installation side of the radar 9, and are received by the radar receiver. After receiving the radar receiver, the radar wave emission point and reflection are calculated. The distance of the point is compared with the preset distance value. If the distance calculated by the radar r...

Embodiment 2

[0030] combined with figure 1 As shown, a kind of anti-trap automobile sunroof control system comprises power supply 1, switch 2, controller 3, relay 4 and motor 5, and described switch 2 is connected with described power supply 1, controller 3 and relay 4 respectively, and described Relay 4 is connected with controller 3 and motor 5 respectively, and described controller 3 comprises automobile computer ECU and radar receiver, and described radar receiver is connected with a plurality of radars 9, and described controller 3 is also connected with 4 water sensors 6.

[0031] working principle:

[0032] When any 2 or more water sensors 6 among the 4 water sensors 6 detect water, they send a signal to the controller 3, and the controller 3 automatically sends the sunroof fully open to the relay 4 immediately after receiving the signal from the water sensor 6. signal, and the isomorphic relay 4 controls the motor 5 to realize the automatic full opening of the sunroof, so as to a...

Embodiment 3

[0035] combined with Figure 1-3 As shown, on the basis of Embodiment 2, in order to simplify the system structure and reduce the system space occupancy rate, the relay 4 includes a turn-on relay 41 and a turn-off relay 42 connected in parallel, and the turn-on relay 41 and the turn-off relay 42 are connected to each other in turn. The motor 5 and the switch 2 are connected in series.

[0036] In order to improve the safety of the system and prevent damage to the system caused by failure or short circuit of other electrical systems of the automobile, a fuse 8 is arranged between the relay 4 and the controller 3 .

[0037]In order to realize the multi-stage adjustment of the system in non-wading conditions, in this embodiment, the switch 2 includes a switch KA21, a switch KB22, a switch KC23, and a switch KD24. The relays 42 are connected in series; the switch KB22 and the switch KD24 are connected in parallel with each other and then connected in series with the opening relay...

Abstract

The invention discloses a control system for an anti-pinch sunroof. The control system comprises a power source, a switch, a controller, a relay and a motor, wherein the switch is connected with the power source, the controller and the relay; the relay is connected with the controller and the motor; and the controller comprises an automobile computer ECU and a radar receiver, wherein the radar receiver is connected with a plurality of radars. According to the control system disclosed by the invention, through the adoption of a radar detecting technology, the anti-pinch function of the sunroof is realized, so that the problem that during closing, the sunroof easily pinches a human body is solved; detection can be realized by the radars without using physical members, so that the problem that in the prior art, the sunroof is returned after pinching accidents occur, and personal injury still exists is solved, and the anti-pinch effect without contact is achieved.

Description

technical field [0001] The invention relates to the field of automobile sunroof control systems, in particular to an anti-pinch automobile sunroof control system. Background technique [0002] As one of the most convenient means of transportation, cars provide irreplaceable convenience for people's daily life and travel. In order to increase the comfort and breathability of driving, almost most of the models are equipped with corresponding models. Different types of sunroofs are used to improve the driving experience of the car; since the sunroofs are all driven by electric motors, it often occurs that the sunroofs will clamp the head and neck of the child during the closing process, causing injuries and even causing individual casualties. The existing sunroof has a certain anti-pinch function after a series of improvements, but the existing anti-pinch technology is basically based on the detection and control of the working conditions of the actuator to achieve anti-pinch,...
