The present invention relates to a method and system for controlling lights and wipers on a vehicle. The control method is applied in a control system. The control system includes a wiper switch control unit and a vehicle body controller. The wiper switch control unit includes a wiper combination switch and a wiper switch control unit. The wiper single-chip microcomputer, the wiper combination switch is connected with the wiper single-chip microcomputer, the wiper single-chip computer and the body controller are connected through the CAN bus, and the body controller collects the current CAN signal of the wiper combination switch through the CAN bus; the wiper combination switch is also connected through a hard line Connect with the body controller, and the body controller collects the current wiper combination switch hard wire signal through a hard wire; the method includes the following steps: the body controller does not receive the current wiper combination switch CAN signal; then receives the current wiper combination switch hard wire Signal, according to the hard-wired signal of the current wiper combination switch to control the wiper work, to avoid the sudden failure of the wiper.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for controlling vehicle lights and wipers. Background technique [0002] In the automotive field, a light rain sensor is usually installed on the windshield, and the Body Control Module (BCM) is connected to the wiper motor, low beam and position lights respectively. ambient light, and send the rain signal to the body controller, the body controller controls the wiper motor to drive the wiper to wipe, and at the same time sends the light signal to the body controller, and the body controller controls the low beam or Switching on and off of position lights. [0003] Robustness is the ability of the system to survive in abnormal and dangerous situations. Whether a control system is robust is the key to its real practical application. The design of modern control systems has taken robustness as one of the most important Design indicators, for example, in th...
