Trailer-type RV roll interactive early warning system and roll interactive early warning method

Abstract

The invention discloses a roll interactive early warning system and roll interactive early warning method for a trailer-type RV, comprising a steering angle sensor, a control unit module, a wireless transmission module, a sensor response module, a warning light response module, a fault detection module, and a control unit. The module includes ECU and RV microprocessor; the steering angle sensor is connected with the tractor electronic control unit, the tractor electronic control unit is connected with the tractor end of the wireless transmission module, the RV end of the wireless transmission module is connected with the sensor response module, and the RV sensor responds The module, the warning light response module and the fault detection module are all connected with the RV microprocessor, and the output terminal of the fault detection module is connected with the RV terminal of the wireless transmission module. The present invention is more suitable for two-part separated models of trailer type RVs, the judgment is accurate and comprehensive, the wireless transmission of signals avoids the potential safety hazards caused by too many wires, the service life is improved, and the early warning signals are conducted in both directions, which is efficient and safe.

Description

technical field [0001] The invention relates to a trailer-type car body and an automotive electronic system, in particular to a trailer-type caravan interactive warning system for roll, and belongs to the field of vehicle engineering. Background technique [0002] Trailer-trailer RVs are prone to rollovers when they change lanes and turn at high speeds when driving in a straight line. From theoretical analysis, the reasons for their instability and rollovers are summarized into two aspects: First, when the tractor is driving normally, too many lane changes cause the RVs to roll over. The yaw rate is too large to make it roll; the second is that the vehicle speed is too fast or the steering angle is too large when turning, which causes the roll angle of the RV and the height of the chassis from the ground is too large. [0003] The existing technology mainly designs an integrated wired roll warning for the whole car, detects the vehicle condition through the load sensor, and ...
