Problems solved by technology

[0005] The disadvantage of this method is that too many wiring harnesses are used, and the functions are not easy to expand
In addition, there is a common safety hazard in the current anti-trap sunroof: that is, when the vehicle is turned off, if the owner forgets to close the sunroof, the owner uses the remote control to fortify. At this time, the door is locked and the body control module BCM considers the fortification successful.

Embodiment Construction

[0036] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0037] This embodiment discloses a sunroof anti-pinch system. The system connects the body control module and the sunroof anti-pinch module through the LIN bus to form a LIN network. The BCM is the master node of the LIN network, and the anti-pinch module is the slave of the LIN network. node. When the BCM receives the switch input signal, the BCM sends the key gear position signal, the sunroof opening and closing command, and the centralized control closing and opening signal to the sunroof anti-pinch module through the LIN bus. The sunroof anti-pinch module controls the motor to run after receiving the relevant commands. And periodically send sunroof motion status, sunroof position signal, motor thermal protection signal, motor voltage signal, motor fault signal and other fault diagnos...

Abstract

The invention relates to a roof window anti-pinch system and a control method thereof, and the roof window anti-pinch system comprises a car body control module, a roof window anti-pinch module and an LIN bus, wherein the car body control module is connected with an entire car CAN bus, the roof window anti-pinch module is connected with the car body control module through the LIN bus for constituting an LIN network, the car body control module is used for removing remote information from the CAN bus and sending a signal to the roof window anti-pinch module through the LIN bus, and the roof window anti-pinch module is used for carrying out the corresponding control after receiving the signal.

Description

technical field [0001] The invention relates to the technical field of automobile electric sunroof anti-pinch technology and the field of vehicle-mounted bus LIN bus control technology, in particular to a sunroof anti-pinch system and a control method thereof. Background technique [0002] With the development of automobile technology and network communication technology, the networking of automobile information communication is an inevitable trend. The diversification of automotive information and communication has promoted the emergence and development of automotive hierarchical networks. LIN is a new low-speed serial bus with simple structure, flexible configuration and low cost. It is mainly used as an auxiliary network or sub-network of high-speed buses such as CAN. In occasions with low bandwidth requirements, simple functions, and low real-time requirements, such as the control of body electrical appliances, using the LIN bus can effectively simplify the network wiri...
