Vehicular secondary started engine rotating speed control module and control method thereof

Abstract

The invention relates to a vehicle-mounted terminal control module and a control method thereof, in particular to a vehicle-mounted terminal module based on a controller area network (CAN) bus and capable of limiting the rotating speed of an engine after a speed limiting instruction is given and when a vehicle is restarted. The vehicle-mounted terminal module comprises a power supply, an advancedRISC machine (ARM) processor and a CAN transceiver; a vehicular secondary started engine rotating speed control module is installed in a vehicle-mounted terminal host; the vehicle-mounted terminal host comprises a terminal computer, a communication module and the vehicular secondary started engine rotating speed control module; the vehicle-mounted terminal host is installed in a cab of the vehicle, a subscriber identity module (SIM) card is arranged in the communication module, and the communication module is communicated with a system platform through a mobile communication network; the vehicular secondary started engine rotating speed control module and the communication module share the ARM processor; and the vehicular secondary started engine rotating speed control module is mounted in the CAN of the vehicle. By using the control module and the control method, a user can remotely give the speed limiting instruction to the vehicle by simple operation; and after the vehicle is restarted, the rotating speed of the engine of the vehicle is limited.

Description

technical field [0001] The invention relates to a vehicle-mounted terminal control module and a control method thereof, in particular to a vehicle-mounted terminal module based on a controller area network (CAN) bus, which can limit the engine speed when the vehicle restarts after a speed limit command is issued. Background technique [0002] Since cars are expensive and highly mobile items, safety is difficult to guarantee. On the one hand, vehicle sellers face malicious non-repayment behaviors of loan car buyers, on the other hand, car owners often encounter vehicle theft incidents. Although many vehicles are equipped with global positioning systems, which can be used to locate and track vehicles, this method has great disadvantages due to the strong mobility of vehicles. At present, the main method is to install a special lock module on the vehicle, and cut off the fuel and power of the vehicle after the lock command is issued remotely. But in doing so, the vehicle woul...
