Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0037] Figure 1 This is a flowchart illustrating a vehicle control method according to an exemplary embodiment. Figure 1 As shown in an exemplary embodiment, this vehicle control method is applied to a vehicle control system, which includes a body controller, a retarder controller, a vehicle operation acquisition device, and a fuel cut-off control device. The method includes steps 110 to 130, which are described in detail below:
[0038] Step 110: If the key switch in the vehicle operation acquisition device is closed, the body controller is used to simulate the accelerator pedal signal and the accelerator pedal signal is sent to the retarder controller.
[0039] In embodiments of the present invention, such as Figure 2As shown, the body controller, the vehicle operation acquisition device, and the retarder controller are connected through a CAN bus (Controller Area Network Bus) for communication; the vehicle operation acquisition device and the fuel cut-off control device are directly connected with the body controller, and the information in the vehicle operation acquisition device is acquired by the body controller, and the fuel cut-off control device is controlled by the body controller.
[0040] When the body controller detects that the key switch is closed, the simulated accelerator pedal signal is sent to the retarder controller through the CAN bus, and the accelerator pedal signal represents that the accelerator pedal of the vehicle is not stepped on.
[0041] In step 120, the retarder of the vehicle is started by using the retarder controller based on the accelerator pedal signal.
[0042] In the embodiment of the present application, the retarder controller starts the retarder based on the accelerator pedal signal, so that the retarder can enter the working state at any time.
[0043] In step 130, the vehicle operation state is determined by using the vehicle operation acquisition device or the retarder controller, and the fuel cut-off control device is controlled based on the vehicle operation state.
[0044] In the embodiment of the present application, the vehicle operation state is determined by using the vehicle operation acquisition device or the retarder controller, and the fuel cut-off control device is controlled based on the vehicle operation state. The fuel cut-off control device is a fuel cut-off electromagnetic valve, which is a device for controlling fuel supply by using electromagnetic principle. When the fuel cut-off control device works, the fuel supply to the engine of the vehicle is stopped, and vice versa, when the fuel cut-off control device does not work, the fuel supply to the engine is normal.
[0045] In the embodiment of the present application, the retarder can enter the working state at any time by simulating the accelerator pedal signal. During the working process of the retarder, the vehicle operation state is determined by using the vehicle operation acquisition device or the retarder controller, and the fuel cut-off control device is controlled, so as to avoid the simultaneous working of the retarder braking and the engine speed rising, complete the adaptation of the non-electric control engine and the hydraulic retarder, and protect the hydraulic retarder and the engine.
[0046] In an exemplary embodiment of the present application, the vehicle operation state is determined by using the vehicle operation acquisition device, and the fuel cut-off control device is controlled based on the vehicle operation state, including:
[0047] The vehicle operation state is determined by using at least one of the key switch, the clutch switch, the neutral switch, and the engine speed acquisition unit in the vehicle operation acquisition device, and the fuel cut-off control device is controlled based on the vehicle operation state.
[0048] In the embodiment of the present application, when the key switch is closed, it represents that the vehicle is started, and vice versa. When the clutch switch is closed, it represents that the clutch is stepped down, and vice versa. When the neutral switch is closed, it represents that the gearbox is returned to neutral, and vice versa. The engine speed acquisition unit is used to acquire the engine speed. Based on at least one of the key switch, the clutch switch, the neutral switch and the engine speed acquisition unit in the vehicle operation acquisition device, the vehicle operating state is determined, and the control of the stop oil control device is realized.
[0049] In an exemplary embodiment of the present application, the vehicle operating state is determined based on at least one of the key switch, the clutch switch, the neutral switch and the engine speed acquisition unit in the vehicle operation acquisition device, and the stop oil control device is controlled based on the vehicle operating state, which comprises:
[0050] If any one of the key switch is opened, the clutch switch is closed, the neutral switch is opened and the engine speed acquired by the engine speed acquisition unit is lower than the first preset speed threshold, the vehicle operating state is determined as the first operating state, and the stop oil control device is stopped based on the first operating state; wherein the first operating state represents that the stop oil control device is prohibited to be driven;
[0051] If the key switch is closed, the clutch switch is opened, the neutral switch is closed, and the engine speed acquired by the engine speed acquisition unit is higher than the second preset speed threshold, the vehicle operating state is determined as the second operating state, and the stop oil control device is driven based on the second operating state; wherein the second operating state represents that the stop oil control device is driven, and the second preset speed threshold is greater than the first preset speed threshold.
[0052] In the embodiment of the present application, when the retarder enters the working state, if the key switch is closed, the gearbox is not in the neutral position, the driver does not step down the clutch, and the engine speed is greater than the second preset speed threshold (such as 1050 rpm), the stop oil electromagnetic valve is immediately driven to stop supplying oil to the engine; when the retarder is in the working state, if the key switch is opened, the gearbox is returned to the neutral position, the clutch is stepped down, or the engine speed is less than the first preset speed threshold (such as 980 rpm), the stop oil electromagnetic valve is immediately stopped to continue supplying oil to the engine. Through the technical solution provided in the present example, it is ensured that the accelerator pedal is invalid when the retarder is working, and the two do not work at the same time. It is also ensured that when the engine speed is reduced to a certain extent, the engine will not be shut down when the oil continues to be supplied.
[0053] In an example embodiment of the present application, the vehicle operating state is determined by the retarder controller, and the fuel cut-off control device is controlled based on the vehicle operating state, including:
[0054] If the retarder is determined to be in operation by the retarder controller, the vehicle operating state is determined to be a second operating state, wherein the second operating state represents driving the fuel cut-off control device.
[0055] Based on the second operating state, the fuel cut-off control device is driven.
[0056] In the embodiment of the present application, when the vehicle body controller detects that the retarder is in operation, the fuel cut-off control device is driven to work, i.e. the fuel supply to the engine is stopped, so as to avoid the retarder braking and the engine speed-up working at the same time.
[0057] In an example embodiment of the present application, whether the key switch is valid is collected, if not, the EEC2 message related to the position of the accelerator pedal is prohibited to be sent; if the key switch is valid, whether the engine of the vehicle is a non-electronic control engine is further determined, if not, the EEC2 message related to the position of the accelerator pedal is prohibited to be sent, if yes, the EEC2 message related to the position of the accelerator pedal is sent, and the accelerator opening degree signal is filled as 0, i.e. the accelerator pedal is not stepped on. Then, whether the brake torque signal in the ERC1 message is 0 is determined, if yes, the fuel cut-off control device is stopped to be driven, and the accelerator pedal can be normally supplied with fuel; if the brake torque signal is not 0, whether the clutch signal is valid is further determined, if yes, the fuel cut-off control device is stopped to be driven, and the accelerator pedal can be normally supplied with fuel; if the clutch signal is not valid, the neutral switch signal is further determined, if valid, the fuel cut-off control device is stopped to be driven, and the accelerator pedal can be normally supplied with fuel; if the neutral switch signal is not valid, the engine speed is further determined, if less than a first preset threshold, the fuel cut-off control device is stopped to be driven, and the accelerator pedal can be normally supplied with fuel, so as to avoid the engine being off due to the accelerator failure; if the engine speed is greater than a second preset threshold, the fuel cut-off control device is driven, and the accelerator pedal cannot be supplied with fuel, i.e. the accelerator pedal is invalid.
[0058] The neutral signal and the clutch signal collected by the vehicle body controller can also be collected by other controllers and converted into CAN signals to be sent out, and the vehicle body controller performs logical processing. The logical processing function of the vehicle body controller can also be completed by other similar vehicle controllers such as an instrument, a signal collection module, etc.
