Control method for realizing headlamp steering light supplement auxiliary function

Abstract

The invention discloses a control method for realizing a headlamp steering light supplementing auxiliary function. The control method is applied to a vehicle model provided with a CAN bus and a steering angle sensor and comprises the following steps: when an ignition switch is turned on, a dipped headlight switch is turned on and the vehicle speed is within a preset range, if a steering lamp switch is turned on or the steering angle is larger than a preset value, a front fog lamp is controlled to be turned on for auxiliary light supplementing; and when the ignition switch is turned on, a highbeam switch is turned on and the vehicle speed is within a preset range, if the steering lamp switch is turned on or the steering angle is larger than the preset value, the front fog lamp is controlled to be turned on for auxiliary light supplement. Only a bus standard program is modified without adding or changing hardware, the cost of the whole vehicle is not influenced, and when the vehicle turns at night, the fog lamp is turned on to serve as a headlamp auxiliary light supplement during steering, the pavement illumination brightness and width are increased, the night driving safety of thevehicle is improved, the vehicle configuration function is increased, and the product competitiveness is improved.

Description

technical field [0001] The invention belongs to the field of vehicle light control, and relates to a control method for realizing the auxiliary function of headlight turning supplementary light. Background technique [0002] When driving at night, road models mainly rely on headlights for illumination. Ordinary headlights only have two lighting modes, low beam and high beam, and are mainly used for lighting the road ahead. However, when dealing with complex road conditions such as turning at night, the headlights cannot meet the needs of safe driving. [0003] Currently, existing solutions on the market need to add a light source of a corner lamp, and use the light source of the corner lamp to perform auxiliary supplementary light, which leads to an increase in hardware cost. Contents of the invention [0004] The purpose of the present invention is to provide a control method for optimizing the bus logic through message sorting and real vehicle angle testing to realize t...
