The invention discloses a vehicle lamp driving circuit and a vehicle, and the vehicle lamp driving circuit comprises a power supply, a first power supply line, a second power supply line, a low-position brake lamp driving circuit, a high-position brake lamp driving circuit, a low-position brake lamp and a high-position brake lamp. The power supply is electrically connected with the input end of the first power supply circuit and the input end of the second power supply circuit, the output end of the first power supply circuit is electrically connected with the power end of the low-position brake lamp driving circuit, and the output end of the low-position brake lamp driving circuit is electrically connected with the low-position brake lamp and then grounded. The output end of the second power supply circuit is electrically connected with the input end of the high-position brake lamp driving circuit, and the output end of the high-position brake lamp driving circuit is electrically connected with the high-position brake lamp and then grounded. Only when the two power supply lines fail, the whole brake lamp function fails, and therefore the probability that the whole brake lamp function fails is effectively reduced.
本发明公开一种车辆灯具驱动电路及车辆,车辆灯具驱动电路包括:供电电源、第一供电线路、第二供电线路、低位制动灯驱动电路、高位制动灯驱动电路、低位制动灯以及高位制动灯,供电电源分别与第一供电线路的输入端以及第二供电线路的输入端电连接,第一供电线路的输出端与低位制动灯驱动电路的电源端电连接,低位制动灯驱动电路的输出端与低位制动灯电连接后接地,第二供电线路的输出端与高位制动灯驱动电路的输入端电连接,高位制动灯驱动电路的输出端与高位制动灯电连接后接地。本发明只有两路供电线路均失效时,才会导致制动灯功能整体失效,从而有效降低制动灯功能整体失效的概率。
