In addition, the plug includes a male and a female head, located at the rear of the tractor and at the front of the trailer, respectively.
Preferably, in the trailer load control and drive system provided by the present invention, the tractor side controller is a body area controller or a central gateway.
Preferably, in the trailer load control and drive system provided by the invention, the communication line with the shielding layer is a CAN line with the shielding layer, and does not support the function of waking up the network by any frame, so as to avoid mistaken waking up by the network.
In a second aspect of the present invention, there is provided a method of controlling a trailer load control and drive system, comprising the steps of:
The invention has the following beneficial effects:
firstly, the trailer side controller is detachably arranged on the trailer, the trailer outer lamp drive and inner lamp drive loads are integrated in the trailer, and the tire pressure receiving module and the printed antenna are arranged in the trailer, so that the trailer is convenient to change and modify, the functions of tire pressure monitoring at the trailer end, inner lamp drive and the like are compatible by using lower cost, more reliable trailer load control and drive are supported, and the wire harness cost is reduced;
secondly, after the tractor is connected with the trailer, the tractor side controller identifies the message of the trailer side controller, confirms the trailer state connection, and sends an instruction to the trailer side controller through a communication line with a shielding layer to drive an inner lamp, an outer lamp and a tire pressure monitoring load of the trailer, so that the 'trailer state detection' without the LED outer lamp flicker defect is realized, and remote software flashing is supported;
thirdly, the relay is arranged, the relay is closed under the condition that the trailer function is not forbidden by the tractor, the relay is disconnected after the tractor meets the dormancy condition, the trailer module is powered off, and the whole vehicle enters a low power consumption mode; under the trailer theftproof mode, after the tractor satisfied the dormancy condition, will no longer break the relay, the trailer module stops driving the load, nevertheless continues to send periodic message, and tractor side controller carries out the polling monitoring to the area shielding layer communication line, triggers the trailer theftproof after the message is lost in succession and reports to the police, has realized "trailer theftproof warning".
