The invention provides a control method and system for safe driving of an electric vehicle, and the control method comprises the steps that when the vehicle runs and an acceleration safety protection mode is started, a power control domain determines an acceleration safety vehicle speed limit value according to detected road condition information; the difference value between the real-time vehicle speed and the acceleration safety vehicle speed limit value is calculated, and when overspeed reaches a first set threshold value, a vehicle machine is controlled to remind a driver of safe driving through voice; when the first duration lasts and overspeed reaches a second set threshold value, the vehicle is limited not to accelerate any more, and the vehicle machine is controlled to ask the driver whether emergency stop is needed or not through voice; and executing corresponding emergency stop safety measures according to a received reply instruction of the driver. According to the driving safety control strategy, vehicle speed limitation of the vehicle under various road environments and various safety accidents caused by abnormal acceleration of the vehicle are scientifically guaranteed, the driving safety and reliability of the electric vehicle are improved, and the driver and passenger safety is guaranteed.

    本发明提供一种电动汽车安全驾驶控制方法和系统,控制方法包括:在车辆行驶且开启加速安全保护模式时,动力控制域根据检测的路况信息确定加速安全车速限速值;计算车辆实时车速和所述加速安全车速限速值之间的差值,当超速达到第一设定阈值时,控制车机语音提醒驾驶员需要安全行驶;当持续第一时长,超速达到第二设定阈值时,限制车辆不再加速,并控制车机语音询问驾驶员是否需要紧急停车;根据接收的驾驶员的回复指令,执行相应的紧急停车安全措施。本发明的行驶安全控制策略科学地保证了车辆在各种道路环境下车速的限制,各种车辆异常加速导致的安全事故,提高了电动汽行驶的安全性和可靠性,保证司乘安全。
