Problems solved by technology

However, the current return circuit may have poor conduction due to the influence of the environment, which will cause the waveform of the return signal received by the wiper controller to be unstable.
Due to the inaccuracy of the return signal, the wiper controller will misjudge the actual position of the wiper blade, which will lead to the wrong stop or wipe of the wiper blade, which will affect the normal operation of the wiper

Abstract

The invention discloses a control system and method for a vehicle wiper and the vehicle. The system comprises a temperature sensor used for detecting the environment temperature, a wiper return circuit used for providing return signals, and a wiper controller connected with the wiper return circuit to provide power for the wiper return circuit and receive the return signals. The wiper controller is further used for acquiring the environment temperature and regulating the supply current of the wiper return circuit according to the environment temperature to control the wet current of the wiper return circuit to keep unchangeable so as to enable the return signals to be stable. According to the system, the actual position of a wiper blade of the wiper can be accurately judged, mistaken shutdown or mistaken wiping of the wiper blade is avoided, and normal work of the wiper is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a control system of a vehicle wiper, a control method of a vehicle wiper and a vehicle. Background technique [0002] The wiper controller of the vehicle can judge that the wiper blade of the wiper is in the stop position by receiving the effective return signal sent by the return circuit. However, the current return circuit may have poor conduction due to the influence of the environment, which will cause the waveform of the return signal received by the wiper controller to be unstable. Due to the inaccuracy of the return signal, the wiper controller will misjudge the actual position of the wiper blade, which will lead to the wrong stop or wipe of the wiper blade, which will affect the normal operation of the wiper. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain ex...
