System and method for locking vehicle based on GPS satellite positioning

Abstract

The invention discloses a system and a method for locking a vehicle based on GPS satellite positioning, and relates to the technical field of remote vehicle control. The method comprises the followingsteps: S001, a GPS positioning module positions the vehicle; S002, a cloud determines that whether positioning information is out of range or not, and sends a control command to the vehicle; S003, the vehicle judges that whether preconditions are met or not, and the vehicle is locked if the preconditions are met; S004, the cloud receives the obtained returned result, saves the result and sends the result to a display module; and S005, the display module shows that the vehicle is locked. T he vehicle locking instruction is issued to the vehicle out of the limited range through the GPS positioning module, a transmitter ECU receives the vehicle locking instruction and communicates the instruction to an unlocking / locking module, and an engine receives the vehicle locking instruction, and thenexecutes the vehicle locking instruction at a next vehicle ignition time, so the problem of difficulty in planning and control of existing enterprise vehicles or leased vehicles is solved.

Description

technical field [0001] The invention belongs to the field of remote vehicle control, in particular to a vehicle locking system and method based on GPS satellite positioning. Background technique [0002] With the continuous improvement of people's living standards, commercial vehicle manufacturers need to install driving recorders on vehicles to report vehicle positioning, turn signals, and brake signals in real time. Considering the cost and the functional limitations of ordinary driving recorders, we use the CAN bus communication technology and the 1939CAN communication protocol to realize the data interaction between the vehicle driving recorder and the commercial vehicle engine ECU, and implement it through the engine CAN lock communication protocol. Commands are issued to control the vehicle engine speed, torque and other operations. In addition, the intelligent remote car locking solution will not force the car to be locked and braked during driving (which may easily ...

AI Technical Summary

Problems solved by technology

[0003] Since the connection between the car driving recorder and the cloud server is still based on the traffic function of the data card of the traditional operator, there are certain requirements for the communication signal of the data card, but the overdue loan vehicle, leased vehicle or enterprise vehicle It is often forbidden for people to use it privately, but is there a system that can standardize the trajectory of the vehicle, and it is often impossible to monitor such vehicles, resulting in unnecessary losses for enterprises or bank loans
