Problems solved by technology

[0005] When the driver releases the alert button, the KM1 contact of the delayed disconnection relay will not be disconnected within a certain period of time, but the VCU / TCU cannot receive the traction command, and there is no L_brake command at the same time, and the vehicle is in a idling state

Embodiment Construction

[0013] The present invention will cancel the delay disconnection relay and the self-holding circuit of KM2. The functions of the above-mentioned original circuit will be collected and preliminarily sorted through the IO module of the TCMS, and finally sent to the VCU / TCU through the MVB train network. The logic of traction, braking command and self-locking is formed. In addition, the VCU / TCU can also determine the duration of the release of the alert button to trigger the braking according to the speed signal transmitted by the speed sensor. When the train is at 50KM / h, release the vehicle for 5 seconds and apply the brakes.

[0014] The logic of the vigilance system of the present invention is described as follows:

[0015] Taking into account the characteristics of low-floor vehicles and social vehicles running together, full manual driving, etc., the scope of the vigilance button has been expanded from only using the driver controller handle vigilance button to: using the ...

Abstract

The invention discloses a control circuit of a vehicle alert trigger mode. The control circuit comprises a control source. The control source is connected with a driver controller alert handle switch, an independent alert switch, a sand spreading switch, a magnetic track brake switch and an electric whistle switch. The driver controller alert handle switch, the independent alert switch, the sand spreading switch, the magnetic track brake switch, the electric whistle switch and a driver controller handle are all connected into a TCMS module. The TCMS module is in communication with a VCU / TCU.

Description

technical field [0001] The invention relates to the field of vehicle circuit control circuits, in particular to a control circuit for vehicle vigilance triggering. Background technique [0002] In the prior art, the driver's alert button usually adopts a self-reset button on the main handle of the driver controller, and the timing of the alert button generally adopts a time relay. Once the driver releases the vigilance button for a certain period of time, the vehicle will trigger the brake. After the brake is triggered, the vehicle must wait until the vehicle is stationary before releasing the brake and towing the vehicle again. like figure 1 shown. [0003] figure 1 The specific working process: when the driver presses the vigilance button, the delay power-off relay KM1 is energized and closed. When the vehicle does not start (0 speed), the KM2 relay will be energized. After KM2 is energized, on the one hand The contact of KM1 and its own contact form a self-holding cir...
