Passenger car passing light beam height adjusting control system and method based on virtual switch

Abstract

The invention relates to a passenger car passing light beam height adjusting control system and method based on a virtual switch, and the system comprises a vehicle-mounted information entertainment display screen, a car body controller, a headlamp dimming motor, a headlamp dimming mechanical mechanism, a whole car public CAN communication network and a whole car wire harness. The vehicle-mounted information entertainment display screen is connected with the vehicle body controller through a whole vehicle public CAN communication network, the vehicle body controller is connected with the headlamp dimming motor through a whole vehicle wire harness, and the headlamp dimming motor is connected with the headlamp dimming mechanical mechanism through a clamping structure. The method comprises the steps of entering a dimming mode, selecting a dimming height gear and exiting the dimming mode. According to the system and method for adjusting the height of the passing light beam of the passenger car based on the virtual switch, the passing light height gear is selected through the virtual switch on the vehicle-mounted information entertainment display screen, the passing light beam height adjusting function is achieved, the number of mechanical switches is reduced, space and cost are saved, and the science and technology feeling of the space in the passenger car is improved.

Description

technical field [0001] The invention belongs to the technical field of passenger cars, and in particular relates to a control system and method for adjusting the height of a low beam beam of a passenger car based on a virtual switch. Background technique [0002] In order to ensure the safety of driving at night and meet the requirements of relevant regulations, the height of the low beam beam will be adjusted according to the different load conditions of the vehicle during the use of passenger cars to ensure that the low beam beam is at a reasonable position. The principle is to output different motor signal voltages to the front headlight dimming motor through the dimmer switch, so that the motor control arm is maintained at different positions, and the headlight mechanical mechanism is driven to adjust the height of the low beam beam to meet the different heights of the vehicle's low beam. location requirements. [0003] Existing passenger cars generally switch the motor...
