Detailed Description
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a flowchart of a control method of a new energy vehicle according to an embodiment of the present invention. As shown in fig. 1, the method includes:
step S11, detecting the current vehicle speed and the current opening degree of an accelerator pedal;
specifically, the embodiment of the invention is preferably a single-pedal control mode, namely, the accelerator pedal is mainly used for controlling the acceleration and the braking of the new energy vehicle, and the brake pedal is only used for assisting when necessary. The single pedal control function can be generally integrated in a whole vehicle control module, and the whole vehicle control module can control the switching of the single pedal control mode and the normal control mode. The embodiment of the invention can detect the current vehicle speed by using the vehicle speed sensor and detect the current opening of the accelerator pedal by using the opening sensor.
Step S12, determining the request torque of the accelerator pedal based on a preset relation table according to the current vehicle speed and the current opening degree of the accelerator pedal, wherein the preset relation table comprises a relation that the request torque of the accelerator pedal is negative torque when the current opening degree of the accelerator pedal is larger than 0;
the preset relation table can be obtained by calibrating according to the relation between the speed of the new energy vehicle, the opening degree of an accelerator pedal of the new energy vehicle and the requested torque of the accelerator pedal. The calibration may be performed manually, such as by manual testing. The controllability of the vehicle is brought to the target by continuously adjusting the requested torque of the accelerator pedal. For example, a graph (also referred to as an accelerator MAP) of the preset MAP may be as shown in fig. 2, a portion below a vehicle resistance curve (in the graph, a dotted line) is a deceleration region of the vehicle, and a straight line represents a torque of 0, and a large portion between 0% and 30% of the accelerator opening corresponds to a request torque below the straight line and in the deceleration region, that is, a negative torque may be used as a torque request of the accelerator to decelerate when a corresponding vehicle speed is reached and the accelerator opening is substantially between 0% and 30%. Therefore, the preset relationship table includes a relationship in which the requested torque of the accelerator pedal is negative torque when the current opening degree of the accelerator pedal is greater than 0, and of course, also includes a relationship in which the requested torque of the accelerator pedal is positive torque when the current opening degree of the accelerator pedal is greater than 0 (for example, the current opening degree of the accelerator pedal is 70%, at which the requested torque of the accelerator pedal is positive torque regardless of the vehicle speed of the new-energy vehicle, and the new-energy vehicle is in an acceleration state). The invention uses the negative torque as a part of the request torque to decelerate instead of using the energy recovery function module, and can decelerate when the opening degree of the accelerator pedal is larger than 0, thereby avoiding the instantaneous great drop of the request torque in the switching process from acceleration to deceleration, having strong controllability and leading a driver to easily find out the proper pedal opening degree to control the vehicle.
In addition, as shown in fig. 2, in the graph of the preset relationship table of the present invention, as the vehicle speed increases, the change of the requested torque of the accelerator pedal is a smooth curve, and for the same vehicle speed, the requested torque of the accelerator pedal corresponding to the change is almost the same (even the opening degree of the accelerator pedal can be made to be in direct proportion to the requested torque) with the same opening degree change, that is, if the requested torque of the accelerator pedal is determined according to the preset relationship table of the present invention, the requested torque of the accelerator pedal can be made to have no abrupt change no matter whether the new energy vehicle accelerates or adjusts the opening degree of the accelerator pedal, and the controllability of the vehicle is enhanced.
And step S13, controlling the new energy vehicle to run according to the requested torque of the accelerator pedal.
Specifically, the manner of controlling the new energy vehicle to run is shown in fig. 3, and includes steps S31-S32:
step S31, determining the output torque of the motor of the new energy vehicle according to the request torque of the accelerator pedal;
specifically, the output torque of the motor is determined based on the requested torque of the accelerator pedal and the requested torque of other control commands, such as the requested torque of the constant-speed cruise function, the lifting torque of the electronic antiskid device and the like, and the vehicle control module can output the output torque according to the priority of various torques, wherein the lifting torque of the electronic antiskid device takes precedence, and the requested torque of the constant-speed cruise function and the requested torque of the accelerator pedal take the larger one. The output torque of the motor is the requested torque of the accelerator pedal without the influence of other control commands.
And step S32, controlling the new energy vehicle to run according to the output torque.
Specifically, the speed of the new energy vehicle is related to the output torque of the motor, and after the output torque of the motor is determined, the motor is controlled to output according to the torque so as to control the new energy vehicle.
Fig. 4 is a block diagram of a control device of a new energy vehicle according to an embodiment of the present invention. As shown in fig. 4, the apparatus includes: the device comprises a detection unit 1 and a control unit 2, wherein the detection unit 1 is used for detecting the current vehicle speed and the current opening degree of an accelerator pedal; the control unit 2 is configured to: determining the requested torque of the accelerator pedal based on a preset relation table according to the current vehicle speed and the current opening degree of the accelerator pedal, wherein the preset relation table comprises a relation that the requested torque of the accelerator pedal is negative torque when the current opening degree of the accelerator pedal is larger than 0; and controlling the new energy vehicle to run according to the requested torque of the accelerator pedal.
Further, the preset relation table is obtained by calibrating according to the relation among the speed of the new energy vehicle, the opening degree of an accelerator pedal of the new energy vehicle and the requested torque of the accelerator pedal.
Further, the control unit 2 is further configured to: determining the output torque of a motor of the new energy vehicle according to the request torque of the accelerator pedal; and controlling the new energy vehicle to run according to the output torque.
Further, the control unit 2 is further configured to: and when the requested torque of the accelerator pedal is negative torque, controlling the new energy vehicle to decelerate.
The above-described embodiment of the control apparatus of the new energy vehicle is similar to the above-described embodiment of the control method of the new energy vehicle, and details thereof are not repeated here.
The invention also provides a new energy vehicle which comprises the control device of the new energy vehicle.
The present disclosure also provides a machine-readable storage medium having stored thereon instructions for causing a machine to execute the control method of a new energy vehicle described above.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
