Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle assisted driving, and in particular to a cruise control circuit for a new energy vehicle. Background Art

[0002] Cruise control is a convenient car feature that allows the driver to set a specific speed and the vehicle can automatically maintain this speed. Once the driver starts the function, there is no need to keep pressing the accelerator, which helps reduce fatigue during long-distance driving.

The brake interrupt function needs to be used during the cruise control process. Under the conventional solution, two independent brake signal detection and control systems are required to prevent one system from causing the cruise control to be incorrectly interrupted when the vehicle computer sends a brake speed control signal.

[0018] Specifically, the VOUT_1 signal in the control module is first amplified by a signal amplifier and then fed back to a voltage-controlled pulse generator to generate a speed regulation pulse signal, which is then fed back to the CPU of the vehicle computer to control the vehicle speed regulation.

[0019] Specifically, the control module also includes an eleventh resistor R11 and a second light-emitting diode D2. One end of the eleventh resistor R11 is connected to the VOUT_2 signal, the other end of the eleventh resistor R11 is connected to the anode of the second light-emitting diode D2, and the cathode of the second light-emitting diode D2 is connected to the ground.

[0020] Specifically, the voltage divider circuit is used to replace the on-board computer CPU to input the signal to INPUT_2.

[0021] Specifically, the trigger is a D-type trigger.

[0022] Specifically, the first switch SW1 is a self-resetting button switch.

[0023] In the present invention, the first switch SW1 is a start and stop button for a one-touch cruise control, INPUT_1 is a brake signal, INPUT_2 is a vehicle speed signal, VOUT_1 is a fixed speed signal, VOUT_2 is an indication signal, VREF is a voltage reference signal, and CLK is a clock signal. When the first switch SW1 is closed, the power signal is fed back to the third pin of the ninth trigger U9 via the second solid-state relay RL2, the output signal of the fifth pin of the ninth trigger U9 is input to the third inverter U3 in one way, and is input to the first transistor Q1 in another way, the third inverter U3 is cut off, the seventh pin of the second digital potentiometer U2 is started through the third resistor R3 loop, and the CPU of the vehicle computer is input via the INPUT_2 pin when The front vehicle speed signal is sent to the inverting terminal of the first operational amplifier U1. Assuming that there is no fixed speed at present, the first operational amplifier U1 has no output in the initial state. The fourth inverter U4 outputs a high-level signal to the control electrode of the fifth thyristor U5. The fifth thyristor U5 turns on the circuit. The power supply is input to the sixth AND gate U6 through the first transistor Q1 and the fifth thyristor U5. At the same time, the output state of the first operational amplifier U1 is fed back to the second digital potentiometer U2. The CPU inputs the CLK clock signal to the first pin of the second digital potentiometer U2. The second digital potentiometer U2 increases the voltage at the terminal connected to the first resistor R1 and feeds it back to the first operational amplifier U1. After the terminal voltage is greater than the input of the INPUT_2 pin, the first operational amplifier U1 outputs, and the fourth inverter U4 is cut off, and because the first transistor Q1 is turned on, there is still current at the anode of the fifth thyristor U5, and the fifth thyristor U5 still passes through the ninth resistor R9 circuit. The eighth thyristor U8 is turned on by the output of the first operational amplifier U1. The power supply is input to the sixth AND gate U6 through the first transistor Q1 and the eighth thyristor U8. After the voltage exists at both ends of the sixth AND gate U6, the output signal is fed back to the third pin of the ninth trigger U9 through the first diode D1. The output of the fifth pin of the ninth trigger U9 is cut off, and the third inverter U3 outputs a signal to the seventh pin of the second digital potentiometer U2. The second digital potentiometer U2 stops adjusting, and another signal is fed back to the third pin of the seventh trigger U7. The fifth pin of the seventh trigger U7 outputs a signal to the tenth optocoupler Module U10, the tenth optocoupler module U10 is coupled, and the power supply enters the ground loop through the collector, emitter, and first solid-state relay RL1 coil of the tenth optocoupler module U10. The contact of the first solid-state relay RL1 is switched to the state shown in the figure, and VOUT_1 outputs a signal to the CPU of the vehicle computer to perform cruise control. At the same time, the fifth pin of the seventh trigger U7 outputs a signal to the second solid-state relay RL2 coil, and the contact of the second solid-state relay RL2 is switched. When the cruise is turned off, the first switch SW1 is pressed again, and the signal is input to the third pin of the seventh trigger U7 through the second solid-state relay RL2 and the fourth diode D4. The fifth pin of the seventh trigger U7 is cut off, and the first solid-state relay RL1 is switched to turn off the VOUT_1 output.When the seventh trigger U7 outputs, VOUT_2 is fed back to the second light-emitting diode D2 through the eleventh resistor R11, and the second light-emitting diode D2 indicates the current cruise state. In this embodiment, INPUT_1 is connected to the third pin of the seventh trigger U7, and the cruise recovery after interruption is restarted by the second switch SW2. When the cruise is turned off by the first switch SW1, the voltage signal at the second digital potentiometer U2 and the first resistor R1 is not changed. Pressing the first switch SW1 again can resume the speed setting, or pressing the second switch SW2 again can resume the cruise. That is, when resetting the speed, the cruise can be resumed by braking or manually shutting down the cruise through the second switch SW2.

[0024] Taking into account the need to control the vehicle speed for balanced driving due to road conditions and road resistance during cruising, when the vehicle computer is in the braking speed regulation stage, the feedback brake signal will be erroneously interrupted. Therefore, in this embodiment, the INPUT_1 signal is not directly fed back to the third pin of the seventh trigger U7, but is input through the third pin of the fourteenth operational amplifier U14. Since there is no obvious deceleration in the braking speed regulation during constant speed driving, the fluctuation range of the brake signal is small and smooth, while the deceleration is obvious during active braking and the brake signal fluctuates greatly. Therefore, the brake signal is first input to the tenth trigger U7 via INPUT_1. The four operational amplifiers U14 are in phase, and the twelfth resistor R12 is pulled down when there is no signal input to the fourteenth operational amplifier U14 to prevent the fourteenth operational amplifier U14 from outputting the power supply voltage. The seventeenth resistor R17 and the fourteenth operational amplifier U14 form a follower circuit to feed back the INPUT_1 signal to the first capacitor C1 for fluctuation detection of the brake signal. At this time, the first capacitor C1 couples the signal and feeds it back to the thirteenth operational amplifier U13. When the signal inputted by INPUT_1 fluctuates steadily, the capacitive reactance of the first capacitor C1 increases, and the signal is then transmitted through the first capacitor C1. The fifteenth resistor R15 is decoupled, and the thirteenth operational amplifier U13 can perform feedback amplification signal weakening, which is lower than the VREF signal input to the twelfth operational amplifier U12. When the fluctuation range of the INPUT_1 input signal is large, the signal input to the first capacitor C1 through the fourteenth operational amplifier U14 and the seventeenth resistor R17 increases, the capacitive reactance of the first capacitor C1 decreases, and the voltage at the in-phase terminal of the thirteenth operational amplifier U13 rises. After negative feedback amplification, the signal is input to the twelfth operational amplifier U12, and the twelfth operational amplifier U12 outputs a signal to the second transistor Q2. The second transistor Q2 is turned on, the signal of the fifth pin of the second digital potentiometer U2 is fed back to the third pin of the seventh trigger U7, the tenth optocoupler module U10 stops coupling, the second transistor Q2 is turned off, the first solid-state relay RL1 switches to cut off the VOUT_1 signal output, and the cruise is interrupted. The twelfth operational amplifier U12 inputs VREF at the in-phase terminal as the reference voltage, and the third diode D3 is used for signal interception to prevent the signal from being input to the third pin of the ninth trigger U9 through the first diode D1 and causing a fault output. The second transistor Q2 is also used to prevent the cruise from being resumed due to braking when there is no cruise. The signal amplifier is used to amplify the VOUT_1 signal, and the voltage-controlled pulse generator generates a vehicle speed regulation pulse signal according to the amplified voltage signal to the CPU of the driving computer to control the vehicle speed regulation.
