Description

A locomotive intelligent control system based on a vehicle body control module Technical Field

[0001] This utility model relates to the field of locomotive electronic control technology, and in particular to a locomotive intelligent control system based on a vehicle body control module. Background Technology

[0002] The electrical control system relies on breakthroughs in power electronics, computer control, and automation technologies. By integrating intelligent diagnostics, condition monitoring, and network communication functions, it supports advanced application scenarios such as autonomous driving of vehicles. It achieves precise and coordinated control of core functions such as locomotive traction, braking, and signal transmission, significantly improving energy utilization and operational reliability.

[0003] Traditional locomotive electrical control systems typically employ multiple relays to control different functional modules, such as IG relays, fan control relays, headlight control relays, oil pump relays, multi-level temperature control for seat heating, and multi-level control for handlebar heating. This decentralized control method has the following drawbacks: multiple relays and their associated wiring increase system complexity and cost; installation and layout are cumbersome and space-consuming; relays are mechanical switches, which are prone to contact aging and poor contact over long-term use; the overall vehicle structure and data layout are not rationally arranged, resulting in low system stability and reliability; fault diagnosis is complex, requiring individual inspection of relays and their wiring during maintenance, which is time-consuming and labor-intensive; and the level of intelligence is low, as the traditional relay and switch method cannot achieve emergency braking reminders, intelligent diagnostics, or monitoring of braking signals, making it difficult to meet the multi-functional and intelligent networking requirements of modern locomotives. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a locomotive intelligent control system based on a vehicle body control module to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a vehicle intelligent control system based on a vehicle body control module, comprising: a vehicle body control module, a sensor module, and an actuator module;

[0006] The vehicle control module is communicatively connected to the sensor module and the actuator module, and is used to receive transmitted information and generate control signals based on the information to perform control.

[0007] The sensor module is used to monitor the working status of various components of the locomotive in real time and feed the data back to the body control module.

[0008] The actuator module receives control signals sent by the vehicle body control module to modify its working status.

[0009] In one embodiment, the vehicle body control module includes: an intelligent diagnostic module;

[0010] The intelligent diagnostic module is used to monitor the system status in real time and generate fault codes.

[0011] In one embodiment, the body control module further includes: an IG relay, a fan control relay, an oil pump control module, a headlight control relay, a seat heating multi-level temperature control module, a handle heating multi-level control module, a turn signal control relay, and a brake light control relay.

[0012] In one embodiment, the sensor module includes a temperature sensor, a current sensor, a voltage sensor, and a brake switch.

[0013] In one embodiment, the actuator module includes a fan motor, an oil pump, a seat heater, a handlebar heater, a headlight, a turn signal, and a brake light.

[0014] As can be seen from the above, the intelligent locomotive control system based on the vehicle body control module provided by this utility model reduces the use of relays and their associated wiring through integrated design, thereby lowering system costs. The vehicle body control module uses solid-state electronic components instead of mechanical relays, avoiding problems such as contact aging, poor contact, cumbersome installation, and excessive space occupation, thus improving system stability and reliability and optimizing the layout space of the vehicle's structural data. The intelligent diagnostic function can quickly locate faults, reducing maintenance time and costs. After collecting relevant signals, data sharing and collaborative control with other products in the vehicle are achieved through the CAN bus, providing indispensable support for the locomotive to achieve assisted driving functions such as emergency braking and cruise control.

[0022] Figure 1 shows a system structure diagram of a vehicle intelligent control system based on a vehicle body control module, including: a vehicle body control module 10, a sensor module 11, and an actuator module 12.

[0023] The Body Control Module 10 (BCM) serves as the core control unit. It includes functions such as IG relays, fan control relays, headlight control relays, multi-level seat heating temperature control, multi-level handlebar heating control, and emergency braking warning. The BCM communicates with other electronic control units (ECUs) of the locomotive via a CAN bus to achieve data sharing and collaborative control.

[0024] The vehicle body control module includes: an intelligent diagnostic module.

[0025] Figure 2 shows the workflow of the intelligent diagnostic module. The intelligent diagnostic module is a built-in fault diagnosis algorithm in the body control module 10. It can monitor the system status in real time, identify faults, and generate fault codes, facilitating quick fault location and troubleshooting by maintenance personnel.

[0026] The sensor module 11 is used to monitor the working status of various components of the locomotive in real time and feed the data back to the body control module 10. The sensor module 11 includes: IG relay, fan control relay, oil pump control module, headlight control relay, seat heating multi-level temperature control module, handle heating multi-level control module, turn signal control relay, and brake light control relay, etc., and is used to monitor the working status of various components of the locomotive in real time and feed the data back to the body control module 10.

[0027] The actuator module 12 receives control signals from the body control module 10 and modifies its operating status. The actuator module 12 includes a fan motor, oil pump, seat heater, handlebar heater, headlights, turn signals, brake lights, etc., and its operating status is directly controlled by the BCM.

[0028] Figure 3 shows a schematic diagram of the system framework of a locomotive intelligent control system based on a vehicle body control module.

[0029] The body control module 10 replaces traditional relays with an internally integrated control circuit, directly controlling actuators such as the fan, headlights, seat heating, and handlebar heating through the actuator module 12, reducing the use of external relays and simplifying the wiring layout.

[0030] Figure 4 shows a schematic diagram of the internal structure of the vehicle body control module 10.

[0031] The body control module 10 uses the CAN bus signal provided by the ABS assembly to control the turn signals to provide an emergency braking warning when the set conditions are met; the body control module 10 also sends signals to the electronic fuel injection ECU via the CAN bus, and the electronic fuel injection ECU activates the cruise control function after receiving the signal and meeting the conditions.

[0032] The body control module 10 monitors the system status in real time through the sensor module 11. When an abnormality is detected, it automatically generates a fault code and sends it to the instrument panel or remote terminal via the CAN bus to remind the user to perform maintenance.

[0033] In one embodiment, a method for using a vehicle intelligent control system based on a vehicle body control module is as follows:

[0034] Step 1: Install the vehicle control module. Install the vehicle control module in the box under the seat of the locomotive, and connect it to the locomotive's actuators and other ECUs via power lines, signal lines, CAN bus, etc.

[0035] Step 2, sensor module placement: Place corresponding sensors near key components such as fans, headlights, seat heaters, and handlebar heaters to monitor their working status in real time.

[0036] Step 3: Connect the actuator module. Connect the fan motor, headlights, seat heaters, handlebar heaters, and other actuators directly to the output port of the body control module, and let the body control module control their working status.

[0037] Step 4: Activate the intelligent diagnostic function. Pre-set the fault diagnosis algorithm in the body control module. When the system detects an abnormality, it automatically generates a fault code and sends it to the instrument panel or remote terminal via the CAN bus.

[0038] This utility model provides a locomotive intelligent control system based on a body control module. Through integrated design, it reduces the use of relays and their associated wiring, lowering system costs. The body control module uses solid-state electronic components instead of mechanical relays, avoiding problems such as contact aging, poor contact, cumbersome installation, and excessive space occupation, thus improving system stability and reliability and optimizing the layout of vehicle structural data. Intelligent diagnostic functions can quickly locate faults, reducing maintenance time and costs. After collecting relevant signals, it shares data and coordinates control with other vehicle products via the CAN bus, providing indispensable support for the locomotive to achieve assisted driving functions such as emergency braking and cruise control.
