Description

Technical Field

[0001] The present invention belongs to the technical field of electric vehicle assisted cornering, and in particular relates to an electric vehicle assisted cornering method, system, storage medium and vehicle. Background Art

[0002] When the vehicle is driving outdoors or off-road, it may encounter potholes of varying sizes. When passing through small bumps or steps, the vehicle can rely on its own creep torque to pass the bump, but when encountering large bumps or steps, the driver needs to operate to pass the bump. If the driver steps on the throttle opening too small, the vehicle's driving force is small and it cannot pass the bump. Since the torque required for the vehicle to pass the bump is large, but the torque required after passing the bump becomes smaller, when the driver passes the bump, he needs to step on the accelerator deeply to pass the bump, and after passing the bump, he needs to quickly release the accelerator and switch to the brake to prevent the vehicle from rushing forward. The entire operation process tests the driver's driving skills. If the operation is improper, the vehicle may rush forward, which not only has a bad driving experience, but also easily causes safety accidents.

[0003] Relevant technical solutions have been proposed in the prior art to solve such technical problems. For example, the Chinese invention patent with the authorization announcement number: CN112537209 B discloses a vehicle and its remote control driving method and storage medium, wherein the vehicle remote control driving method includes: detecting that the vehicle is in remote control driving mode; collecting vehicle speed information and driving torque information; judging whether the vehicle is in a bump-crossing condition according to the vehicle speed information and the driving torque information; determining that the vehicle is in the bump-crossing condition, obtaining the bump-crossing additional torque; compensating the driving torque according to the bump-crossing additional torque; and driving the vehicle over the bump according to the driving torque. Since this method requires multiple sensors and controllers to participate in detection and processing, an additional slope sensor is required; and the basic torque, slope compensation torque, bump-crossing torque, etc. need to be calibrated during the bump-crossing process, and the calibration amount is large. Therefore, the system structure of the bump-crossing method is complex, the control strategy is complex, and the implementation cost is high. In addition, since torque control is adopted, the vehicle runs unsteadily during the bump-crossing process, and the user driving experience is poor.

[0004] A new method for assisting electric vehicles in crossing bumps is needed to solve the above technical problems. Summary of the invention

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Embodiment 1: like Figure 1 As shown, the present invention discloses a method for assisting electric vehicles in crossing a hill, comprising the following steps: S1: The infotainment system IVI determines whether the user selects the assisted cornering function. If so, it sends a request instruction to activate the assisted cornering function to the vehicle controller and executes step S2; if not, it maintains the current state; S2: After receiving the request command, the vehicle controller VCU reads the vehicle driving state, power battery state, drive motor system state, gear state, accelerator pedal state, brake pedal state and current vehicle speed state, and determines whether the above states all meet the requirements of the auxiliary crossing function. If so, the vehicle controller sends a working mode switching command and a speed control command to the drive motor controller; executes step S3; if not, processes the state that does not meet the auxiliary crossing function; Among them, when all the conditions are met, including the vehicle is in ready state, the power battery is in a fault-free state, the drive motor system is in a fault-free state, the gear is in D / R gear state, the accelerator pedal is in a zero opening state, the brake pedal is in a depth of not less than 50%, and the current vehicle speed is in a zero speed state, it is judged to meet the requirements of the assisted bump crossing function.

[0022] The status that does not satisfy the assisted bump crossing function is processed, specifically including: when the vehicle controller VCU determines that the vehicle is in a non-ready state, the power battery is in a faulty state, or the drive motor system is in a faulty state, the assisted bump crossing function status information is sent to the infotainment system. After the infotainment system receives the status information and determines that the status information is in an inactivated state, the assisted bump crossing function is terminated. In actual application, the user can be reminded by displaying "the assisted bump crossing function cannot be activated" on the display screen. When the vehicle controller determines that the gear is not in the D / R gear state, the accelerator pedal is in a non-zero opening state, the brake pedal is in a depth state not greater than 50%, and the current vehicle speed is in a non-zero vehicle speed state, it sends the auxiliary bump crossing function status information to the infotainment system. After receiving the status information, the infotainment system determines that the status information is in an adjustable state and makes corresponding adjustments to the unsatisfied status. During actual driving, in order to facilitate timely adjustments, the infotainment system IVI can also inform the user of the unsatisfied status by means of voice reminders and text reminders; for example: "Please put the gear in D or R gear", "Please release the accelerator pedal", "Please step on the brake pedal", "Please stop the vehicle", and read and judge each status again.

[0023] S3: After receiving the working mode switching instruction and the speed control instruction, the drive motor controller switches the working mode from the torque mode to the speed mode, sets the target speed of the drive motor to zero, and feeds back the current working mode to the vehicle controller; after receiving the working mode feedback, the vehicle controller sends the status information of the auxiliary bump crossing function to the infotainment system; S4: After receiving the status information, the infotainment system determines whether the assisted cornering function is activated. If so, execute step S5; if not, maintain the current state; S5: The infotainment system determines whether the user chooses to enter the assisted cornering function. If so, execute step S6; if not, maintain the current state; S6: The vehicle controller reads the brake pedal status and determines whether the brake pedal depth meets the requirements of the auxiliary step-over function. The specific depth of the dynamic pedal is: the brake pedal depth is not greater than 10%. If so, send the drive motor target speed N to the drive motor controller 目标 After receiving the control command, the drive motor controller will drive the motor according to the actual speed N 实际 , drive motor target speed N 目标 The difference between the actual speed of the drive motor N 实际 Perform PI adjustment to achieve the target speed N of the drive motor 目标 , and then control the drive motor to drive the motor target speed N 目标 To achieve vehicle crossing the ridge; where N 目标 is the calibration value; PI regulation is a commonly used regulation method in engineering technology. The actual speed of the drive motor N 实际 and the target speed N of the drive motor 目标 The greater the difference, the greater the proportional constant Kp and integral constant Ki. When making specific adjustments, if the actual speed of the drive motor N 实际 ≤Drive motor target speed N 目标 , the output torque of the drive motor is ≥ 0. If the actual speed of the drive motor is N 实际 >Drive motor target speed N 目标 , the drive motor output torque is <0.

[0024] S7: The vehicle controller reads the vehicle driving status, power battery status, drive motor system status, gear status, accelerator pedal status, and brake pedal status. When any status meets the requirements for exiting the auxiliary bump crossing function, the auxiliary bump crossing function status information is sent to the drive motor controller and the infotainment system. After receiving the status information, the drive motor controller exits the speed mode when it determines that the status information is an exited state; after receiving the status information, the infotainment system ends the auxiliary bump crossing function when it determines that the status information is an exited state; at this time, the infotainment system IVI can remind the user by displaying "The auxiliary braking function has been exited, please take over the vehicle" on the display screen.

[0025] Among them, when any one of the following conditions is met: the vehicle is in a non-ready state, the power battery is in a faulty state, the drive motor system is in a faulty state, the gear is in a non-D / R gear state, the accelerator pedal is in an opening state of not less than 10%, and the brake pedal is in a depth state of not less than 40%, it is judged to meet the requirements of the exit assisted bump crossing function.
