In a second aspect, an embodiment of the present invention provides a method for selecting a power takeoff mode.
In an embodiment, referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a method for selecting a power-take-off mode according to the present invention. As shown in fig. 1, the method for selecting the power take-off mode includes:
step S10, when a power takeoff opening signal is monitored, detecting whether a preset condition is met;
in this embodiment, a power takeoff switch is arranged on the vehicle, and when the power takeoff switch is closed by a user through operation, a power takeoff starting signal can be monitored by the vehicle control unit VCU, and at this time, whether a preset condition is met or not is detected. The preset conditions are set according to actual needs, and the subsequent steps can be performed only when the preset conditions are met.
Further, in an embodiment, the step of detecting whether the preset condition is met includes:
detecting whether a vehicle is in a starting state, whether a gear of a gearbox is an N gear, whether the vehicle speed is less than a preset vehicle speed, whether the gearbox has a fault and whether a hand brake signal exists; and if the vehicle is in a starting state, the gear of the gearbox is N, the vehicle speed is less than the preset vehicle speed, the gearbox has no fault and a hand brake signal exists, determining that the preset condition is met.
In this embodiment, it is determined that the preset condition is met only when the vehicle is in a starting state, the gear of the transmission is N, the vehicle speed is less than the preset vehicle speed, the transmission has no fault, and the hand brake signal is present.
Step S20, if a preset condition is met, activating an electromagnetic valve of the power takeoff;
in this embodiment, if it is detected that the preset condition is met, the power takeoff solenoid valve is activated, so that the power takeoff solenoid valve starts to work, the power takeoff enters a gear, the state of the power takeoff is fed back to the transmission controller TCU through a hard wire, and the TCU feeds back the state to the VCU.
Step S30, detecting whether the gear of the gearbox is N gear or not;
in this embodiment, the power take-off mode is divided into two categories, namely a parking power take-off mode and a driving power take-off mode, and in order to determine whether the parking power take-off mode or the driving power take-off mode is selected at present, the determination needs to be performed according to the gear position of the gearbox. Therefore, it is necessary to detect whether the transmission gear is N.
Step S40, if the gear of the gearbox is N gear, determining a power take-off mode according to whether an uploading rotating speed request exists or not and whether an accelerator pedal request exists or not;
in this embodiment, if the gear of the transmission is N, it indicates that the vehicle is currently in a parking state, and at this time, the power take-off mode needs to be determined according to whether an on-load rotation speed request exists and whether an accelerator pedal request exists.
Further, in one embodiment, the step of determining the power-take mode based on whether there is an on-board speed request and whether there is an accelerator pedal request comprises:
and if the loading rotating speed request does not exist and the accelerator pedal request exists, determining that the power take-off mode is the first parking power take-off adjustable rotating speed mode.
In this embodiment, if there is no upper-mounted speed request and there is an accelerator pedal request, that is, the transmission gear is N, the upper-mounted controller is not activated, and the accelerator is stepped on, it may be determined that the power take-off mode is the first parking power take-off adjustable speed mode. In this mode, the VCU requests a variable speed from the motor controller in response to an accelerator pedal request, and the motor controller responds to the speed request.
Further, in an embodiment, the step of determining the power-take mode according to whether the loading rotating speed request exists and whether the accelerator pedal request exists further comprises the following steps:
and if the loading rotating speed request exists, determining that the power take-off mode is a second parking power take-off adjustable rotating speed mode.
In this embodiment, if there is a power-on rotational speed request, that is, the gear of the transmission is N, and a power-on rotational speed request sent from the power-on controller is received, it may be determined that the power-off mode is the parking power-off adjustable rotational speed mode two. In this mode, the upper part does not respond to the throttle state, and requests the rotating speed from the VCU according to the work requirement, the VCU responds to the rotating speed request, and requests the variable rotating speed from the motor controller, and the motor controller responds to the rotating speed request. Specifically, the upper controller requests the rotating speed to the VCU through the CAN bus or the hard-wire form, wherein the use scene of the hard-wire form is relatively limited, and the hard-wire form is mainly used for the situation that the number of the required rotating speeds is small, for example, when 2 rotating speeds are available, the switch 1 represents the rotating speed a, the switch 2 represents the rotating speed B, when the operator closes the switch 1, the VCU detects the signal, sends the rotating speed request a to the motor controller, closes the switch B, sends the rotating speed request B, and each switch represents a fixed rotating speed; the CAN bus mode is that the controller sends rotating speed to the VCU in real time, and the rotating speed CAN be changed. The CAN bus transport requires the VCU and the controller to execute the same transport protocol.
Further, in an embodiment, the step of determining the power-take mode according to whether the loading rotating speed request exists and whether the accelerator pedal request exists further comprises the following steps:
and if the loading rotating speed request does not exist and the accelerator pedal request does not exist, determining that the power take-off mode is the parking power take-off fixed rotating speed mode.
In this embodiment, if there is no upper-loading rotational speed request and no accelerator pedal request, it is determined that the power-take mode is the parking power-take fixed rotational speed mode. In this mode, the VCU requests a fixed speed from the motor controller, which responds to the speed request. Wherein, the fixed rotating speed is preset according to actual needs.
And S50, if the gear of the gearbox is not N gear, determining a power take-off mode according to whether a hand brake signal exists or not and whether an accelerator pedal request exists or not.
In this embodiment, if the gear of the transmission is not N, it indicates that the vehicle is in a driving state, and at this time, the power take-off mode needs to be determined according to whether a handbrake signal exists and whether an accelerator pedal request exists.
Further, in one embodiment, the step of determining the power-take mode according to whether the handbrake signal is present and whether the accelerator pedal request is present comprises:
and if the hand brake signal does not exist and the accelerator pedal request exists, determining that the power take-off mode is the driving power take-off mode.
In this embodiment, if there is no handbrake signal and there is an accelerator pedal request, it is determined that the power take-off mode is the driving power take-off mode. In this mode, the VCU sends a torque request based on accelerator pedal opening and the power takeoff speed responds based on powertrain torque split ratio.
Further, in one embodiment, the step of determining the power-off mode according to whether the handbrake signal is present and whether the accelerator pedal request is present further comprises:
and if the hand brake signal exists or the accelerator pedal request does not exist, outputting a failure prompt of the self-adaptive power taking mode.
In this embodiment, if there is a handbrake signal or there is no accelerator pedal request, and there is no corresponding power take-off mode under such conditions, that is, the determined power take-off mode is empty, a failure prompt of the adaptive power take-off mode is output to inform an operator that the power take-off mode cannot be automatically selected currently.
In the embodiment, when the power takeoff opening signal is monitored, whether the preset condition is met is detected; if the preset condition is met, activating the electromagnetic valve of the power takeoff; detecting whether the gear of a gearbox is N gear or not; if the gear of the gearbox is N gear, determining a power take-off mode according to whether an uploading rotating speed request exists and whether an accelerator pedal request exists; and if the gear of the gearbox is not N gear, determining a power take-off mode according to the existence of a hand brake signal and the existence of an accelerator pedal request.
