DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0015] Please refer to Figure 1 The utility model provides a technical scheme: a non-inductive low-voltage power-on control system, including VCU controller 3, VCU controller 3 is connected with the seat pressure switch 2 of detecting personnel on the car and the safety belt switch 1 of whether the safety belt is closed respectively.

[0016] VCU controller 3 is also connected with the ON gear relay 5 for power-on.

[0017] As Figure 1 Indicated: ON gear relay 5 is connected with low-voltage power supply 4;Through the above setting, for providing power, guarantee normal low-voltage power-on process.

[0018] As Figure 1 Indicated: ON gear relay 5 is also connected with electrical device 9 participating in high-voltage current process.

[0019] As Figure 1 Indicated: VCU controller 3 is connected with direction column electronic unlocking controller 7, and direction column electronic unlocking controller 7 is connected with direction column electronic unlocking motor 6;Through the above setting, VCU controller 3 sends the command of unlocking direction column electronic lock to direction column electronic unlocking controller 7 through communication transmission line 8, and direction column electronic unlocking motor 6 completes the unlocking command.

[0020] As Figure 1 Indicated: VCU controller 3, direction column electronic unlocking controller 7 and electrical device 9 are connected with communication transmission line 8;Through the above setting, the transmission of signal can be quickly carried out, and it is guaranteed that direction column can be quickly unlocked.

[0021] Working principle: when the sensor of the seat pressure switch 2 is closed, the VCU controller 3 receives a low level signal from the seat pressure switch 2, proving that someone has sat on the seat, when the VCU controller 3 detects that the seat belt switch 1 is closed at the same time, the VCU controller 3 sends a low level signal to control the ON relay 5 to close, at the same time, the ON relay 5 outputs the ON electricity to the electrical device 9 participating in the high voltage current process, and the VCU controller 3 sends an unlocking direction column electronic lock command to the direction column electronic lock controller 7 through the communication transmission line 8, the direction column electronic lock completes the unlocking command, and the low voltage power-on unlocking process is completed. Then by stepping on the brake pedal, the VCU controller 3 completes the high voltage power-on, the vehicle is ready, and the vehicle can normally drive.

[0022] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
