[0002] With the increasing requirements of customers for the driving and riding comfort of vehicles, commercial vehicles are gradually equipped with heating systems such as independent warm air, engine preheating, steering wheel heating, and seat heating. However, since each temperature control subsystem is relatively independent, the driver needs to turn on / off each subsystem according to the usage requirements of each subsystem one by one, which brings a complex operation experience to the driver and reduces the driving pleasure. Summary of the Invention

A trigger signal pin is connected in parallel in the original control circuit. After each sub-heating system controller recognizes the trigger signal of this pin, it controls the system to start heating at a high gear. Therefore, the driver can start each heating system with one key operation, thus quickly meeting the driver's demand for thermal comfort and greatly simplifying the operation complexity of the driver.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0023] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, further definition and explanation thereof is not required in subsequent figures.

[0024] In the description of the present application, it should also be noted that unless otherwise clearly specified and defined, the terms "arranged", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0025] The technical solution of the present application will be explained below in conjunction with specific embodiments.

[0026] Figure 1 is a schematic diagram of an in-cabin one-key heating system based on a parallel integrated switch shown in an exemplary embodiment. The system includes: a one-key temperature control switch, a temperature control controller, and at least two sub-heating systems and sub-heating system controllers;

[0027] The temperature control controller is connected to the one-key temperature control switch and is connected in parallel to the control circuits of each of the sub-heating system controllers, and is configured to identify the on / off signal of the one-key temperature control switch and determine whether to transmit a trigger signal to each of the sub-heating system controllers according to the on / off signal;

[0028] Wherein, when the temperature control controller identifies that the one-key temperature control switch is turned off, the temperature control controller does not send a trigger signal. When the temperature control controller identifies that the one-key temperature control switch is turned on, the temperature control controller transmits the trigger signal to each of the sub-heating system controllers;

[0029] The sub-heating system controller is configured to control the sub-heating system to perform heating work after receiving the trigger signal.

[0030] The present application is a system that uses a parallel circuit and a one-key temperature control switch to realize one-key activation of multiple heating systems. The one-key temperature control switch is in a parallel relationship with the original circuits of each sub-heating system. As Figure 1 shown, when the one-key temperature control switch is turned on, all sub-heating systems start to work. At this time, the heating switches of the sub-heating systems themselves are invalid. When the one-key temperature control switch is turned off, the states of all sub-heating systems depend on the states of their respective heating switches, that is, each sub-heating system returns to its original working state.

[0031] Further, the signal transmission between the temperature control controller and the one-key temperature control switch, and between the temperature control controller and each of the sub-heating system controllers can be achieved through hard wires or LIN lines. Among them, the hard wires communicate with voltage signals, and the LIN lines communicate in the form of messages. Both types of signals can be transmitted through one set of pins, and the controllers can recognize them.

[0032] Furthermore, the functions of the above temperature control controller can be integrated into the vehicle controller. The above one-key temperature control switch is a self-resetting temperature control switch, which is default closed after the vehicle is powered on. When needed, the driver can manually turn it on, and it will automatically turn off after the vehicle is powered off. Therefore, it can be switched between manual on / off, control the one-key activation of multiple heating devices, and can achieve that in the cold winter, all heating devices in the cab can be turned on through one-key switch operation, realizing rapid warming in the cabin.

[0033] In an implementable manner, the sub-heating system includes an independent warm air system, and the sub-heating system controller includes an independent warm air system controller. The independent warm air system burns low-emission diesel in the combustion chamber of the warm air system, heats the air through a heat exchanger, and blows the hot air into the cab to form warm air. This application retains the original independent warm air system and control method of commercial vehicles, and only adds a parallel trigger pin to the control circuit of its controller, that is, the trigger pin of the temperature control controller is added in parallel to the control circuit of the independent warm air system controller;

[0034] When the temperature control controller recognizes that the one-key temperature control switch is turned on, the temperature control controller transmits a trigger signal to the independent warm air system controller. At this time, the independent warm air system controller controls the independent warm air system to start working at the highest level gear, and the heating switch of the independent warm air system is invalid; when the temperature control controller recognizes that the one-key temperature control switch is turned off, the temperature control controller does not send the trigger signal. At this time, the heating switch of the independent warm air system is valid.

[0035] In an implementable manner, the sub-heating system includes an engine preheating system, and the sub-heating system controller includes an engine preheating system controller. The engine preheating system burns diesel in the combustion chamber for heat exchange to heat the engine coolant. This application retains the original engine preheating system and control method of commercial vehicles, and only adds a parallel trigger pin to the control circuit of its controller, that is, the trigger pin of the temperature control controller is added in parallel to the control circuit of the engine preheating system controller;

[0036] When the temperature control controller recognizes that the one-key temperature control switch is turned on, the temperature control controller transmits a trigger signal to the engine preheating system controller. At this time, the engine preheating system controller controls the engine preheating system to start working at the highest level gear, and the heating switch of the engine preheating system is invalid; when the temperature control controller recognizes that the one-key temperature control switch is turned off, the temperature control controller does not send the trigger signal. At this time, the heating switch of the engine preheating system is effective.

[0037] In an implementable manner, the sub-heating system includes a steering wheel heating system, and the sub-heating system controller includes a steering wheel heating system controller. The steering wheel heating system generates heat through an electric heating wire to heat the steering wheel. This application retains the original steering wheel heating system and control method of the commercial vehicle, and only adds a parallel trigger pin to the control circuit of its controller, that is, the trigger pin of the temperature control controller is added in parallel to the control circuit of the steering wheel heating system controller;

[0038] When the temperature control controller recognizes that the one-key temperature control switch is turned on, the temperature control controller transmits a trigger signal to the steering wheel heating system controller. At this time, the steering wheel heating system controller controls the steering wheel heating system to start working at the highest level gear, and the heating switch of the steering wheel heating system is invalid; when the temperature control controller recognizes that the one-key temperature control switch is turned off, the temperature control controller does not send the trigger signal. At this time, the heating switch of the steering wheel heating system is effective.

[0039] In an implementable manner, the sub-heating system includes a seat heating system, and the sub-heating system controller includes a seat heating system controller. The seat heating system generates heat through an electric heating wire to heat the seat. This application retains the original seat heating system and control method of the commercial vehicle, and only adds a parallel trigger pin to the control circuit of its controller, that is, the trigger pin of the temperature control controller is added in parallel to the control circuit of the seat heating system controller;

[0040] When the temperature control controller recognizes that the one-key temperature control switch is turned on, the temperature control controller transmits a trigger signal to the seat heating system controller. At this time, the seat heating system controller controls the seat heating system to start working at the highest level gear, and the heating switch of the seat heating system is invalid; when the temperature control controller recognizes that the one-key temperature control switch is turned off, the temperature control controller does not send the trigger signal. At this time, the heating switch of the seat heating system is effective.
