Abstract

A vehicle light control system, a control method, and an automobile. The system comprises a taillight (3), multiple vehicle light connection lines (2), a vehicle body controller (1) and a taillight controller (37). Multiple vehicle lights are integrated in the taillight (3). Each vehicle light is provided with a signal generator (36). The respective ends of the vehicle light connection lines (2) are connected to the vehicle lights, and the respective other ends thereof are connected to the vehicle body controller (1). The vehicle body controller (1) is used to acquire a distance change signal, determine a target vehicle light from the multiple vehicle lights according to the distance change signal, and control a target signal generator (36) on the target vehicle light to transmit a PWM signal having a preset duty cycle, such that the taillight controller (37) controls the taillight (3) to execute a preset control mode on the basis of the PWM signal having the preset duty cycle. Since the system only uses a vehicle light connection line (2), namely a hardline, to realize control of different taillight modes, the system has low costs and good expandability, thereby solving the problems in the art in which using a CAN bus to control taillight modes incurs high cost and low expandability.

具体的，目前，如图1所示，市场上高端车辆的尾部灯光大多是在车钥匙靠近或远离车辆时，采用CAN总线的方案，实现灯光的控制功能，具体通过感应用户身上的车钥匙与车辆之间的距离，实现用户与车辆靠近或远离的判断，在检测到用户靠近车辆时，车灯控制***控制尾灯反复闪烁或控制尾灯以流水的方式闪烁，从而控制尾灯执行迎宾灯功能，在检测到用户远离车辆时，车灯控制***控制尾灯先大灯闪烁一定时间后再小灯闪烁一定时间，从而控制尾灯执行欢送功能。这种实现方式需要额外增加端口以布置CAN总线，增加了灯具成本，因此，有必要提供一种方案，在不增加成本的同时体现车辆的科技感和时尚感Specifically, at present, as shown in Figure 1, most of the tail lights of high-end vehicles on the market use the CAN bus solution when the car key is close to or away from the vehicle to realize the control function of the light. The distance between vehicles realizes the judgment of whether the user is approaching or away from the vehicle. When it is detected that the user is approaching the vehicle, the headlight control system controls the taillights to flash repeatedly or control the taillights to flash in a flowing manner, thereby controlling the taillights to perform the welcome light function. When it is detected that the user is away from the vehicle, the headlight control system controls the taillights to first flash the headlights for a certain period of time and then the small lights for a certain period of time, thereby controlling the taillights to perform a farewell function. This implementation requires additional ports to arrange the CAN bus, which increases the cost of lamps. Therefore, it is necessary to provide a solution that reflects the sense of technology and fashion of the vehicle without increasing the cost.
