Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Examples
Fig. 1 is a flowchart of a method for automatically identifying and allocating a message identifier of a motor controller of a distributed drive vehicle according to an embodiment of the present invention, which specifically includes:
s1, increasing a corresponding number of hard-wire signal wires on the motor controllers according to the number of the motor controllers.
And S2, connecting corresponding pins of the hardware signal lines with high and low level signals, and taking different numbers obtained through high and low level signal combination processing as identification signals corresponding to message identifiers of the motor controller at different positions.
And S3, identifying message identifiers required to be sent by the motor controllers at different positions according to the identification signals.
Specifically, the corresponding relationship between the number of the motor controllers and the number of the hard wire identification signal wires which need to be added is as follows:
N mcu ＝2 n
wherein, N mcu The number of the motor controllers is mounted on the distributed driving vehicle, and n is the number of hard wire identification signal wires which need to be added on the motor controllers.
Further, the motor controller is not limited to one motor controller for one motor, and may be one motor controller for two motors, and so on.
For example, distributed drive vehicles having different numbers of motor controllers may be accommodated for different numbers of hard-wired identification signal lines. For 1 hard wire identification signal wire, the method can be applied to a distributed driving vehicle with no more than two motor controllers; for 2 hard wire identification signal wires, the method can be applied to distributed driving vehicles with no more than 4 motor controllers; for 3 hard wire identification signal wires, the method can be applied to distributed driving vehicles with no more than 8 motor controllers, and the like.
Further referring to fig. 2, in this embodiment, the number of hard wire identification signal harnesses is determined according to the message identifier identification requirement of the motor control, and corresponding wiring design is performed; all motor message identifiers required by the vehicle are added when the motor controller is designed on the bottom layer according to the requirements of the distributed driving vehicle, CAN ID identification variables are added on the bottom layer of the motor controller and used for storing different numbers obtained by the hard wire identification signals, the CAN ID identification variables are used for automatically identifying the CAN IDs of the motors at different positions of the distributed driving vehicle, and the CAN IDs of the motor controllers at corresponding different positions are called.
For example, and with further reference to fig. 3, if the motor controller has three hard-wire identification signal wires, the hard-wire identification signal wire connection method is shown for three hard-wire signals: setting the high level to 1 and the low level signal to 0, eight combination methods (000, 001, 010, 011, 100, 101, 110, 111) can be obtained, and 000 can correspond to the motor controller 1;001 corresponds to the motor controller 2;010 corresponds to the motor controller 3;011 corresponds to the motor controller 4;100 corresponds to the motor controller 5;101 corresponds to the motor controller 6;110 corresponds to the motor controller 7;111 corresponds to the motor controller 8, and further identifies the message identifier (CAN ID) that the motor controller needs to send out according to the identification variable value.
After the CAN communication protocol of the distributed driving vehicle is determined, CAN IDs sent by motor controllers at different positions are also determined, the hard wire wiring method of the message identifier identification signals of the motor controllers at different positions is determined comprehensively according to the CAN IDs corresponding to the motor controllers at different positions and different CAN ID information corresponding to different numerical values of CAN ID identification variables, and the hard wire identification signal wiring harness is designed according to the hard wire wiring method when the whole vehicle wiring harness is designed.
In this embodiment, by adding the method for automatically identifying and allocating the message identifiers by using the hard wire identification signal wire, an engineer CAN write all the motor controllers on the distributed vehicle into the same version of motor controller software, the motor controllers automatically identify and allocate the CAN IDs according to different installed positions, and send and receive the required CAN IDs, and the engineer is not required to write different motor controller software according to different positions, so that the working efficiency is greatly improved, and meanwhile, a program writing error is avoided.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
