Abstract

A method for controlling automatic turning-on of a steering lamp is executed by a steering lamp control unit integrated on a clock spring. After a vehicle is started, the steering lamp control unit sequentially executes following steps: step a, judging whether a steering angle of a steering wheel is larger than a preset angle or not; step b, judging whether speed of the steering angle of the steering wheel is larger than zero or not; step c, judging whether an accelerator is in the forward gear or not; step d, judging the speed of the vehicle is smaller than a preset speed or not; and step e, judging whether the acceleration of the vehicle is smaller than zero or not. If affirmative answers are obtained from the step a to the step e, the steering lamp control unit publishes a steering lamp control signal for automatically turning on the steering lamp to a CAN / LIN (controller area network / local interconnect network) bus, a combination switch of the vehicle automatically turns on the steering lamp after receiving the steering lamp control signal for automatically turning on the steering lamp from the CAN / LIN bus. The method has the advantage that when a driver forgets to turn on the steering lamp, the steering lamp can be automatically turned on to remind other vehicles to be attentive, thus driving safety performance is improved.

Description

【Technical field】 [0001] The invention relates to a control method for a turn signal lamp, in particular to a control method for automatically turning on the turn signal lamp. 【Background technique】 [0002] The vehicle steering mechanism refers to the steering mechanism whose steering column or processor on the steering gear uses electronic methods to make its motor generate power assistance of corresponding magnitude and direction to assist the driver in steering operations. Steering wheel assembly is an important part of vehicle steering mechanism. Steering wheel assembly includes steering wheel, clock spring and wiring harness (such as figure 1 shown). The steering wheel includes a steering wheel rim, steering wheel spokes and a steering wheel hub, wherein the steering wheel rim is connected to the steering wheel hub through the steering wheel spokes, and the steering wheel is connected to the steering column of the vehicle steering mechanism through the steering wheel...
