The invention relates to a laser radar system and a vehicle. The laser radar system comprises at least two laser radar modules. The synchronous control module comprises a micro-control unit; each laser radar module is electrically connected with the micro-control unit through a wire, and the micro-control unit is used for synchronization of the at least two laser radar modules. Specifically, the micro-control unit generates a clock signal according to setting and synchronously triggers all laser radar modules in the system, and the laser radar modules detect a target area according to the received clock signal and feed back obtained images and spatial distance information to a user side; when the laser radar system is applied to a vehicle, the defects of synchronization error, time delay, lag and the like caused by packet loss of the laser radar system in the data transmission process due to the fact that GPS signals cannot be received can be overcome, and time synchronization of laser radar modules in the sy
