The embodiment of the invention discloses vehicle-mounted early warning equipment and a vehicle, and relates to the technical field of traffic safety. The vehicle-mounted early warning equipment comprises a main control circuit board, a laser radar and an alarm module; the main control circuit board is electrically connected with the laser radar and the alarm module. The laser radar is used for transmitting a first laser signal to the direction of the second vehicle and recording a first moment when the first laser signal is transmitted; receiving a second laser signal reflected by a second vehicle, and recording a second moment when the second laser signal is received; sending the first moment and the second moment to the main control circuit board; the main control circuit board is used for calculating a real-time distance between the second vehicle and the first vehicle based on the first moment, the second moment and the laser signal transmission speed; whether the real-time interval is smaller than a first preset value or not is judged, and if yes, a first alarm signal is sent to an alarm module; the alarm module is used for sending out first alarm information based on the first alarm signal. The embodiment of the invention is applied to a scene of vehicle driving safety detection.
本发明实施例公开一种车载预警设备以及车辆,涉及交通安全技术领域。车载预警设备包括主控电路板、激光雷达以及报警模块;主控电路板分别与激光雷达以及报警模块电连接;激光雷达用于向第二车辆所在方向发射第一激光信号,并记录发射第一激光信号的第一时刻;接收第二车辆反射的第二激光信号,并记录接收第二激光信号的第二时刻;将第一时刻以及第二时刻向主控电路板发送;主控电路板用于基于第一时刻、第二时刻以及激光信号传输速度,计算第二车辆与第一车辆之间的实时间距;判断实时间距是否小于第一预设值,若是,则向报警模块发送第一报警信号;报警模块用于基于第一报警信号,发出第一报警信息。本发明实施例应用于车辆驾驶安全检测的场景。
