Detailed Description
The present invention will be described in detail below with reference to the drawings and the specific embodiments thereof in order to make the objects, technical solutions and advantages of the present invention more apparent.
Aiming at the problem that an electric automobile does not have the function of a track mode and cannot meet the requirement of a driver on violent driving in the prior art, the invention provides a track mode control method, a track mode control device and a vehicle.
In the following, the track mode control method is described in detail in specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a method for controlling a track mode, including:
step 101: after the vehicle is powered up, the racetrack mode on signal is monitored.
The monitoring track mode on signal includes:
monitoring the track mode starting signal through a track mode switch at the bottom of an accelerator pedal; or alternatively, the first and second heat exchangers may be,
monitoring the track mode starting signal through a virtual switch of a central control screen; or alternatively, the first and second heat exchangers may be,
and monitoring the track mode starting signal through an entity key.
It should be noted that, after the vehicle is powered on, the track mode on signal can be monitored by adopting a plurality of methods, preferably, the embodiment of the invention provides three modes, wherein the first mode is to monitor the track mode on signal through a track mode switch at the bottom of an accelerator pedal, as shown in the structural schematic diagram of the track mode switch in fig. 2, a track mode switch 1 is installed at the bottom of an accelerator pedal 2, a detection circuit is arranged in the track mode switch 1 and is connected with a power chassis domain controller (Power chassis domain Control Unit, PDCU) of the vehicle, when a driver steps on the accelerator pedal 2 to the bottom, the track mode switch 1 is triggered, and at this time, the PDCU monitors the track mode on signal; the second is to monitor the track mode starting signal through a virtual switch of a central control screen, wherein the central control screen is provided with a virtual switch, the central control screen is connected with a central control entertainment system controller, after a driver presses the virtual switch, the central control entertainment system controller sends the track mode starting signal to a PDCU, and the PDCU monitors the track mode starting signal; and thirdly, monitoring the track mode starting signal through an entity key, setting an entity key on the vehicle, wherein the entity key is connected with the PDCU through a circuit, and after the driver presses the entity key, the PDCU monitors that the entity key is pressed through the circuit, namely, monitors the track mode starting signal.
After the track mode is started, an instrument control system (Instrument cluster monitor, ICM) controls the instrument to display icons and interfaces matched with the track mode so as to remind a driver of entering the track mode, and meanwhile, the ICM controls the sound simulator to emit sound waves similar to the intense driving of racing vehicles, so that the driving experience of the driver is improved.
Step 102: if the track mode starting signal is monitored, a torque control signal is sent to a driving motor controller of the vehicle, so that the driving motor controller outputs torque with maximum capacity according to the torque control signal; and transmitting a discharge capacity control signal to a battery management system of the vehicle, so that the battery management system outputs power with maximum discharge capacity according to the discharge capacity control signal.
If the track mode start signal is detected, a torque control signal is sent to a driving motor controller of the vehicle, so that the driving motor controller outputs torque with maximum capability according to the torque control signal, and for a two-drive vehicle type, namely, only one of a front driving motor controller (Front Motor Control Unit, f_mcu) or a rear driving motor controller (Rear Motor Control Unit, r_mcu), if the track mode start signal is detected, a PDCU sends a torque control signal to the f_mcu or the r_mcu of the two-drive vehicle type, so that the f_mcu or the r_mcu outputs torque with maximum capability according to the torque control signal; for the four-wheel drive vehicle type, namely, the vehicle is simultaneously provided with an F_MCU and an R_MCU, if the track mode starting signal is monitored, the PDCU simultaneously sends torque control signals to the F_MCU and the R_MCU of the vehicle of the four-wheel drive vehicle type, so that the F_MCU and the R_MCU can output the maximum torque according to the torque control signals, and simultaneously, the PDCU sends a discharge capacity control signal to a battery management system (Battery Management System, BMS) of the vehicle, so that the BMS can output the maximum discharge capacity power according to the discharge capacity control signal, the torque output is more aggressive, and the driving experience of a driver is improved.
The method further comprises the steps of:
and if the track mode starting signal is monitored, sending a closing control signal to an electronic stability control system of the vehicle.
If the track mode on signal is detected, the PDCU sends an off control signal to an electronic stability control system (Electronic Stability Controller, ESC) of the vehicle, requesting the ESC to cancel driving anti-slip, inter-wheel slip control and other controls, so that a driver can conveniently make a series of actions such as "drift" and the like, and a more vigorous driving experience is brought.
After the torque control signal is sent to the driving motor controller of the vehicle, the method further comprises:
monitoring a racetrack pattern shut down signal;
if the track mode closing signal is monitored, the track mode closing signal is sent to a driving motor controller of the vehicle, so that the vehicle enters a normal driving mode; and sending an opening control signal to an electronic stability control system of the vehicle.
The monitoring track mode off signal includes:
after the track mode starting signal is monitored, calculating a sustainable first time length of the track mode according to first state information of the vehicle;
and determining that the track mode closing signal is monitored when the track mode opening duration reaches the first duration.
After the track mode is started, the PDCU calculates a sustainable first time length of the track mode according to first state information of the vehicle, wherein the first state information of the vehicle at least comprises output capability of current torque fed back by the f_mcu and the r_mcu of the vehicle, temperature information and battery pack temperature information fed back by the BMS in the state that the track mode is started, the PDCU calculates a maximum sustainable first time length of the track mode according to the first state information of the vehicle, the maximum sustainable first time length is represented by T1, when the starting duration of the track mode reaches T1, a track mode closing signal is determined to be monitored, the track mode is closed, the vehicle enters a normal driving mode, the pdcontrol f_mcu and the r_mcu are switched to torque output of the normal driving mode, and smooth transition processing from torque output of the track mode to torque output of the normal driving mode is completed.
After the track mode is closed, the PDCU sends a starting control signal to the ESC system of the vehicle, so that the driving safety is improved.
The monitoring track mode off signal includes:
monitoring the opening degree of an accelerator pedal;
and when the opening degree of the accelerator pedal is smaller than a set threshold value and the duration time reaches a second duration time, determining that the track mode closing signal is monitored.
After the track mode is started, if the opening degree of the accelerator pedal is smaller than the set threshold value and the duration reaches the second duration, denoted by T2, the driver is considered to have no need to continue to use the track mode, the track mode closing signal is determined to be monitored, the track mode is closed, the vehicle is enabled to enter the normal driving mode, the PDCU controls the f_mcu and the r_mcu to switch to the torque output of the normal driving mode, and the smooth transition from the torque output of the track mode to the torque output of the normal driving mode is completed, wherein the second duration T2 is not greater than the first duration T1.
After the track mode is closed, the PDCU sends a starting control signal to the ESC system of the vehicle, so that the driving safety is improved.
The method further comprises the steps of:
after the track mode closing signal is monitored at the first time, calculating an interval duration threshold value for restarting the track mode according to the second state information of the vehicle;
after the track mode starting signal is monitored again at the second time, if the interval time between the second time and the first time is longer than or equal to the interval time threshold, a torque control signal is sent to a driving motor controller of the vehicle, and a discharging capacity control signal is sent to a battery management system of the vehicle; otherwise, not responding to the track mode starting signal.
It should be noted that, a period of time is required between when each track mode is turned off and when the next track mode is turned on, which is called a track mode cooling time. From the closing moment of each track mode, the PDCU calculates an interval duration threshold value for restarting the track mode according to second state information of the vehicle, wherein the second state information of the vehicle at least comprises output capacity of current torque fed back by F_MCU and R_MCU of the vehicle, temperature information and battery pack temperature information fed back by BMS in the closing state of the track mode, the PDCU calculates the interval duration threshold value from the next openable track mode in real time according to the second state information of the vehicle, and the interval duration threshold value is represented by T3, namely from the closing of each track mode to the opening of the next track mode, and the interval time is not less than T3.
The method further comprises the steps of:
and if the vehicle fault signal is received, sending the track mode closing signal to a driving motor controller of the vehicle according to the vehicle fault signal.
It should be noted that, if the PDCU receives the vehicle failure signal after the track mode is turned on, the method includes: BMS fault signal and F_MCU, R_MCU fault signal etc. track mode can't continue to work, send to the driving motor controller of vehicle track mode shut down signal to indicate the driver through ICM in the form of characters or sound.
If the PDCU receives the vehicle failure signal, it includes: BMS fault signal and F_MCU, R_MCU fault signal etc., race track mode can't open, also need to indicate the driver through ICM in the form of characters or sound.
