摘要： A programmable turn signal and hazard flasher control system (10, 100) includes a lamp control module (12, 108) coupling a turn signal request unit (14, 106) to a number of turn signal lamps (20-30). The module (12, 108) couples the turn signal request unit (14, 106) to a number of vehicle turn signal lamps (20-26) in a first mode of operation and to a number of vehicle turn signal lamps (20-26) as well as a number of additional turn signal lamps (28, 30) in a second mode of operation to thereby accommodate lighting requirements of a trailer or other towed vehicle or to accommodate different lighting requirements in vehicles of a common vehicle platform. The load current to the turn signal lamps (20-30) in either case flows through a shunt resistor R1, and is controlled by a flasher circuit (54) during normal operation to a first flash rate and during a lamp failure condition to a second faster flash rate. The module (12, 108) further includes a control circuit (62) responsive to an appropriate signal state at a lamp designation control input (34) to provide a predefined load activation signal to the flasher circuit (54) regardless of whether the module (12, 108) is coupled to only a minimum number of vehicle turn signal lamps, or the minimum number of vehicle turn signal lamps as well as a number of additional turn signal lamps.
摘要翻译：可编程转向信号和危险闪光器控制系统（10,100）包括将转向信号请求单元（14,106）耦合到多个转向信号灯（20-30）的灯控制模块（12,108）。模块（12,108）在第一操作模式下将转向信号请求单元（14,106）耦合到多个车辆转向灯（20-26），并将多个车辆转向灯信号灯（20-26 ）以及在第二操作模式下的多个附加转向灯（28,30），从而适应拖车或其它牵引车辆的照明要求，或者适应在公共车辆平台的车辆中的不同照明要求。转向信号灯（20-30）的负载电流在任一情况下流过分流电阻器R1，并且在正常操作期间由闪光器电路（54）控制到第一闪光速率，并且在灯故障状态期间控制到第二更快的速度模块（12,108）还包括响应于灯指示控制输入（34）处的适当信号状态的控制电路（62），以向闪光器电路（54）提供预定的负载激活信号，而不管模块（ 12,108）仅耦合到最小数量的车辆转向灯信号灯，或最小数量的车辆转向灯信号灯以及多个额外的转向灯信号灯。
