Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0045] With the wide application of large-scale integrated circuit (LSI), the processing power of central processing unit (Central Processing Unit, CPU) is getting stronger and stronger, and the external resources are very abundant, so it is easy to realize data acquisition and logical judgment . The development of automotive electronic controllers is becoming more and more concentrated, such as Body Control Module (BCM) and so on. Because the integrated power driver chip has the advantages of high integration, l...

Abstract

The invention discloses a trailer connection state judging method, device, vehicle and storage medium. The method includes: when it is determined that the ignition switch is in an open gear and the vehicle speed is lower than the vehicle speed threshold, determining whether the ABS fault signal of the trailer is valid and determining whether it has been collected When the valid signal of the trailer’s lamp operation is determined to be collected, send the valid signal of the lamp operation to the target lamp indicated in the valid signal of the lamp operation, collect the first operating current of the target lamp, and The first working current judges whether the target lamp is in the open circuit state, and when it is determined that the target lamp is not in the open circuit state or the ABS fault signal is valid, it is determined that the trailer is in the connected state. By combining the ABS fault signal and the working conditions of the trailer lamps, the redundant judgment of the trailer connection status is realized. On the one hand, there is no need to add additional hardware devices. On the other hand, the real-time and accuracy of the trailer connection status are guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to the field of commercial vehicle electronics, and in particular, to a method, device, vehicle, and storage medium for judging the connection state of a trailer. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's material needs, tractors and trailers are currently being used more and more in the commodity transportation industry. In order to realize the tractor's control over the power and braking performance of the trailer, it is necessary to know the connection status of the trailer and the tractor in real time. [0003] At present, the connection state of the trailer can be determined in the following way: add a switch at the connection between the tractor and the trailer, and judge the connection state of the trailer by detecting the state of the switch. The detection switch can be a sensor device that detects whether the tractor is conne...
