Intelligent windscreen wiper system and controlling method thereof based on CAN/LIN bus

Abstract

The invention discloses an intelligent windscreen wiper system and a controlling method thereof, the system comprises an intelligent windscreen wiper controller, a windscreen wiper actuator, a mode switch and a rain mount sensor, the intelligent windscreen wiper controller is integrated in a car body controller, and the windscreen wiper actuator is controlled by the intelligent windscreen wiper controller through a PIN foot, the rain mount sensor and the mode switch are communicated with the intelligent windscreen wiper controller by a LIN, the car body controller which is integrated with the intelligent windscreen wiper controller not only can be used as a node of a CAN network but also can be a main node of a LIN network. A control message and a rain mount detecting signal of a windscreen wiper are received from the LIN bus by the intelligent windscreen wiper controller; and then the intelligent windscreen wiper controller carries out decoding and executes relating control instructions. The intelligent windscreen wiper controller is integrated in the car body controller, the increasing of cost which is caused by singly adding a module is reduced, meanwhile, the information of the intelligent windscreen wiper system is transferred to other modules of the car through a CAN bus, thereby realizing the information sharing, solving the problem of complex external wiring of the traditional windscreen wiper and reducing the failure rate.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to an automobile intelligent wiper system based on a CAN / LIN bus. Background technique [0002] As an essential and important functional part of modern automobiles, the wiper is mainly used to manually adjust the opening and closing, working mode and working speed of the wiper through a combination switch. This wiper system has many disadvantages: it needs to manually control the work of the wiper, which increases the The driving workload of the car owner is reduced, and the driving comfort is reduced; the movement frequency of the hanging arm cannot be automatically adjusted according to the amount of rain; some areas cannot be scraped, and there are dead spots; it is not easy to maintain, etc. It can be foreseen that the development direction of the wiper system in the future must be intelligent control. [0003] With the development of automobile technology and network com...
