[0012] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0013] Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0014] As Figure 1 shown, an electric vehicle chassis and superstructure linkage operation display system includes: a rocker switch 1, a body controller 2 (BCM), a central control screen 3, a vehicle controller 4 (VCU), a superstructure controller 5, and a superstructure actuator 6. The rocker switch 1 is a self-resetting switch.

[0015] The rocker switch 1, as a physical button, transmits the switch quantity signals of the vehicle chassis function operation and the superstructure system operation to the superstructure controller 5 and the body controller 2, including the superstructure speed switch and the rear control switching switch; the body controller 2 is used to collect the hard-wired signals of the rocker switch 1 on the instrument panel and drive the superstructure actuator 6 to work. The actuator includes: a solenoid valve and a motor, and sends the switch state to the bus in the form of a message; the superstructure controller 5 is used to receive the signals of the rocker switch 1 or the signals of the central control screen 3 processed by the vehicle controller 4 and convert them into corresponding control signals and transmit them to the superstructure actuator 6; there are corresponding touch switches on the central control screen 3 for controlling the acceleration and deceleration of the superstructure actuator 6, and receiving the operation status message sent by the superstructure controller 5 and parsing and displaying the content.

[0016] The specific working process is as follows:

[0017] 1. The rocker switch 1 can independently control the superstructure system. The hard-wired signal of the superstructure speed switch on the vehicle instrument panel is connected to the vehicle controller 4, and then the vehicle controller 4 sends an instruction to the superstructure controller 5 to drive the superstructure actuator 6:

[0018] When the motor speed in the upper body actuator 6 is 0, press the acceleration button once, and the motor starts to rotate forward at 135 rpm. Then press the acceleration switch. Each time it is pressed, the motor speed increases by 135 rpm until the maximum speed of 1890 rpm in the forward rotation;

[0019] When the motor speed is 0, press the deceleration button once, and the motor starts to rotate backward at 135 rpm. Then press the deceleration switch. Each time it is pressed, the motor speed increases by 135 rpm until the maximum speed of 1890 rpm in the reverse rotation;

[0020] If the motor is accelerating and the deceleration switch is pressed, the vehicle controller 4 will send a 0 rpm command to the upper body controller 5, and the upper body motor speed will decelerate to 0. Then press the deceleration switch again, and the upper body motor will rotate in reverse;

[0021] If the motor is rotating, the rocker switch 1 gives a command opposite to the motor rotation direction, and the motor will stop; if you want to rotate in the reverse direction, you must wait until the upper body motor stops completely and then press it again to work; this is to prevent the driver from repeatedly misoperating due to the reaction delay of the upper body actuator 6.

[0022] 2. The central control screen 3 can independently control the upper body system; there are speed regulation + and speed regulation - touch buttons in the central control screen 3 with the same function as the rocker switch 1, and the status of the upper body system is displayed in real time: the rotation status of the motor, the speed value of the motor, and the corresponding power parameters, etc.; the central control screen 3 is connected to the vehicle controller 4 through CAN signal transmission. The central control screen 3 sends the control signal to the CAN line, and the vehicle controller 4 reads it and sends the corresponding instruction to the upper body controller 5 to drive the upper body actuator 6; the operations in the central control screen 3 are similar to those of the rocker switch 1. When rotating forward or in reverse, the upper body motor can be accelerated and decelerated by pressing the speed regulation + or speed regulation -; the central control screen 3 also has an anti-misoperation function. Only when the upper body motor speed is 0, the forward and reverse installation switching is effective; when the motor is running, the rotation direction of the motor, the rotation direction of the upper body mechanism, the motor speed, and the speed of the upper body system can be read from the central control screen 3.

[0023] 3. The rocker switch 1 and the central control screen 3 can be linked for control; both the central control screen 3 and the vehicle controller 4 are connected to the vehicle bus through the CAN line. The central control screen 3 can read the information of the vehicle controller 4 and the upper body controller 5 from the vehicle bus. Since the rocker switch 1 is connected to the vehicle controller 4 and its status is sent to the bus, that is, the central control screen 3 can obtain and analyze the status of the rocker switch 1 through the vehicle bus;

[0024] When the acceleration button of the rocker switch 1 is pressed, the upper mounting system controls the motor to rotate forward. After pressing it multiple times, the upper mounting system adjusts the speed to the desired speed. At the moment of pressing, the vehicle controller 4 sends the switch quantity status signal of the rocker switch 1 to the bus. After receiving the speed regulation signal of the rocker switch 1, the central control screen 3 will light up the "Speed Up +" button switch on the central control screen 3, indicating that it is in the state of speed regulation and acceleration at this time;

[0025] When the deceleration button of the rocker switch 1 is pressed, the upper mounting system controls the motor to rotate in the reverse direction. After pressing it continuously, the upper mounting system adjusts the speed to the desired speed. At the moment when the deceleration switch is pressed, the vehicle controller 4 sends the switch quantity status signal of the rocker switch 1 to the bus. After receiving the speed regulation signal of the rocker switch 1, the central control screen 3 will light up the "Speed Down -" button switch on the central control screen 3, indicating that it is in the state of speed regulation and acceleration at this time;

[0026] After pressing the rocker switch 1, the speed regulation operation can continue on the central control screen 3, that is, it can be switched between the operation of the material button and the soft switch. The central control screen 3 and the rocker switch 1 are coordinated by the vehicle controller 4. When the vehicle controller 4 receives the speed regulation signal from the rocker switch 1 or the speed regulation signal from the central control screen 3, it responds according to the order. That is, when two opposite speed regulation signals are received within a short time, the vehicle controller 4 preferentially processes the signal input first and sends a 0 rpm instruction to the upper mounting controller 5 until the speed of the upper mounting motor is reduced to 0.

[0027] In the electric vehicle chassis and upper mounting linkage operation display system, the vehicle chassis control operation and the upper mounting system display are linked. The central control screen 3 can read the status of the upper mounting system from the bus and display it on the central control screen 3. The vehicle controller 4 realizes the coordinated linkage between the operation of the rocker switch 1 and the operation of the central control screen 3. The button operation of the central control screen 3 and the operation of the rocker switch 1 do not conflict and can be effective at the same time. The status of the rocker switch 1 can be displayed on the central control screen 3, and the corresponding chassis functions can be controlled from the central control screen 3. The physical switch button and the touch switch status are linked, which greatly facilitates the driver's operation. The switches do not conflict with each other and can perform operations more quickly and accurately. The status of the chassis and the upper mounting system can be displayed in real time, and the operation is clear and convenient.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
