Abstract

The invention discloses an automobile front windscreen wiper interval-adjustable control system and an automobile front windscreen wiper interval-adjustable control method. The control system comprises an automobile body controller, a combined switch, a front windscreen wiper motor and an ABS (Anti-lock Brake System), wherein the automobile body controller is connected with the combined switch and the front windscreen wiper motor through wiring harnesses; the automobile body controller is connected with the ABS through a CAN (Controller Area Network) bus; the automobile body controller not only obtains a front windscreen wiper interval mode signal and a front windscreen interval time gear signal from the combined switch, but also obtains a real-time automobile speed signal from the ABS through the CAN bus; the automobile body controller adjusts the wiping interval time of front windscreen wipers driven by the front windscreen wiper motor according to the front windscreen wiper interval time gear signal and the automobile speed. By applying the control system and the control method, the stability of control on the interval time of the front windscreen wipers in the driving process of an automobile can be improved; the comfort of driving sight is bettered; meanwhile, the system cost is lowered to a certain extent.

Description

technical field [0001] The invention belongs to the electronic control technology of automobiles, and in particular relates to an intermittently adjustable control system and control method of an automobile front wiper. Background technique [0002] In rainy and snowy days, in order to provide the driver with a clear view and ensure the safety of driving, the front windshield of the vehicle is equipped with a front wiper system to ensure that the rain and snow on the front windshield can be wiped off in time. clear. With the innovation and development of technology, the new control method of adjusting the intermittent time of the front wiper according to the amount of rain has also been initially used in batches, but the realization of the adjustment according to the amount of rain is completed by the rain sensor, adding the rain sensor It will virtually increase the cost of the system, which is not conducive to the mass adoption of vehicles, and the rain sensor also has it...
