Description

Technical Field

[0001] This application relates to the field of vehicle control technology, specifically to a method and device for indicating the battery level of an electric vehicle through brake pedal resistance. Background Technology

[0002] Currently, the biggest concern for electric vehicle users is running out of battery power, which could prevent them from continuing to drive. Therefore, effective warning mechanisms are particularly important. The following are some of the current problems and potential risks that users may encounter:

[0003] 1. Currently, most car manufacturers display the battery level on the instrument panel or central control screen. Users will frequently check the instrument panel and central control screen while driving, which will cause the driver's attention to be distracted and pose a safety risk.

[0004] 2. To address the aforementioned issues, connected car manufacturers use Bluetooth or the internet to transmit battery signals to mobile phones to indicate the current vehicle battery level. When the battery is low, they will emit a sound or vibration to alert the user. This can lead to users becoming overly reliant on their phones or third-party tools. If the phone or tool is lost, there will still be no effective reminder, and the safety risks associated with driving as described in issue 1 will still exist.

[0005] 3. Electricity in electric vehicles is very precious. Daily driving should conserve electricity to ensure normal vehicle operation. The two methods mentioned above will still consume a lot of electricity to ensure the operation of functions. Summary of the Invention

[0057] Figure 3 This is a schematic diagram of an electronic device capable of implementing a method for indicating the battery level of an electric vehicle through brake pedal resistance, as described in an embodiment of this application.

[0058] Among them, 1-motor, 2-worm gear, 3-first gear, 4-second gear, 5-brake pedal. Detailed Implementation

[0059] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0060] In a first aspect, this application provides a method for indicating the battery level of an electric vehicle through brake pedal resistance, mainly comprising:

[0061] Obtain the battery level of an electric vehicle;

[0062] When the battery charge drops below a threshold, a pre-installed resistance device at the brake pedal is activated to provide a rebound force to the brake pedal in the opposite direction of the pedal stroke.

[0063] This application can determine the current battery level based on the resistance feedback when the brake pedal is pressed, thereby avoiding the driver's distraction caused by repeatedly looking at the battery level display on the central control or instrument panel, thus improving driving safety. At the same time, it avoids the risk of not receiving timely reminders if the user's mobile phone or third-party reminder tool is lost.

[0064] In some alternative implementations, providing a rebound force to the brake pedal in the opposite direction to the pedaling direction includes:

[0065] When the battery charge drops below a threshold, the rebound force is continuously increased according to the degree of battery charge consumption during the battery charge reduction process.

[0066] In this embodiment, as the battery continues to decrease, the resistance device does not work before it exceeds a threshold. When the battery is depleted to below the threshold, the resistance device starts to work. As the battery continues to deplete, the resistance generated by the resistance device, i.e., the rebound force, will increase. When the user applies the foot brake, they can make a preliminary judgment on the battery level by the magnitude of the rebound force.

[0067] In some alternative embodiments, the rebound force increases with the increase of the battery power consumption value, and has an exponential trend.

[0068] In this embodiment, when the battery level drops to the threshold, a small rebound force is generated, giving the user a certain rebound feeling during foot braking. As the battery level continues to decrease, the initial rebound force does not change significantly. When the battery is almost completely depleted, the rebound force generated at this time will be large, making the user clearly feel the low battery level.

[0069] In some alternative implementations, providing a rebound force to the brake pedal in the opposite direction to the pedaling direction includes:

[0070] Based on multiple preset thresholds, the brake pedal is provided with multiple different rebound forces, wherein the lower the threshold, the greater the corresponding rebound force provided to the brake pedal.

[0071] In some alternative implementations, the thresholds include three, namely 20%, 40%, and 80% of the battery charge, and providing a rebound force to the brake pedal in the opposite direction of pedaling based on these three thresholds includes:

[0072] When the battery level is below 80%, a first rebound force is applied to the brake pedal.

[0073] When the battery level is below 40%, a second rebound force is applied to the brake pedal.

[0074] When the battery level is below 20%, a third rebound force is applied to the brake pedal.

[0075] Wherein, the first rebound force is less than the second rebound force, and the second rebound force is less than the third rebound force.

[0076] refer to Figure 1 The present application provides a flowchart of a method for indicating the battery level of an electric vehicle through brake pedal resistance, according to an embodiment of this application. The pedal resistance given at different thresholds is different, thereby allowing the user to perceive the remaining battery power.

[0077] In some alternative implementations, providing a rebound force to the brake pedal in the opposite direction to the pedaling direction includes:

[0078] When the battery level drops below a threshold, a first drive signal is given to the drive motor to rotate at a preset speed. The motor drives the resistance device via a shaft to provide the rebound force to the brake pedal. (Refer to...) Figure 2 The resistance device includes a first gear driven to rotate by the motor and a second gear connected to the brake pedal. When the brake pedal is depressed, the second gear and the first gear are intermittently engaged. In the engaged state, the second gear pushes the first gear to rotate, thereby giving the brake pedal a rebound force. After the first gear rotates, it disengages from the second gear and continues to engage with the second gear by being pushed by the brake pedal.

[0079] This application uses a small motor and worm gear to control resistance. When the car's battery is at normal levels, the motor will not work and the worm gear will not interfere with the brake pedal, so users do not have to worry about extra power consumption.

[0080] refer to Figure 2 Compared to existing brake pedals, this brake pedal will have an additional small motor 1 and turbine rotor 2 to control the variable resistance of the brake pedal.

[0081] When the car's battery level is normal, the worm gear will not interfere with the movement of the brake pedal 5, and the brake pedal functions like a normal linear brake pedal. When the change in the car's battery range reaches a threshold, that is, when resistance feedback is required, the motor can be energized to drive the worm gear to rotate the first gear 3. The first gear 3 transmits a counterforce to the second gear 4 to prevent the brake pedal from falling, thereby increasing the resistance of the brake pedal.

[0082] In one specific embodiment, when it is necessary to achieve variable brake pedal resistance, the amount of power supplied to the motor can be controlled. The faster the motor speed, the greater the reaction force applied to the brake pedal 5, and the more resistance the user needs to overcome to press the brake pedal.

[0083] In some alternative implementations, providing a rebound force to the brake pedal in the opposite direction to the pedaling direction includes:

[0084] When the battery charge drops below a threshold, a second drive signal with a preset pressure is provided to the drive actuator, which provides the rebound force to the brake pedal by pushing the resistance.

[0085] Understandably, besides Figure 2 In addition to generating different amounts of rebound force through motor speed, different rebound forces can also be designed through an actuator. The actuator functions as a spring, except that the fluid inside can be changed to generate different elastic forces, that is, to give the brake pedal different rebound forces.

[0086] In some alternative embodiments, the method of indicating the electric vehicle's battery level via brake pedal resistance further includes:

[0087] The battery level is sent to the locomotive display.

[0088] While the brake pedal provides feedback on the battery level, the system also needs to send the received battery level signal to a display or other instrument panel indicator so that the user can check it at their convenience. This battery level signal, which indicates the battery's remaining range, is collected by a battery level sensor.

[0089] In some alternative embodiments, the method of indicating the electric vehicle's battery level via brake pedal resistance further includes:

[0090] Obtain the threshold value input by the user for causing the resistance to generate the rebound force;

[0091] The threshold is written into the driver program that drives the resistor, thereby enabling customization of the threshold.

[0092] The implementation of this embodiment shows that users can customize the threshold according to their own preferences, that is, customize the linkage value of the resistance, thereby improving the driving experience.

The device for indicating the battery level of an electric vehicle by means of brake pedal resistance includes:

[0094] A battery power acquisition module is used to acquire the battery power of an electric vehicle.

[0095] The rebound force generation module is used to drive a pre-installed resistance device at the brake pedal to provide a rebound force to the brake pedal in the opposite direction to the pedaling direction when the battery charge drops below a threshold.

[0096] In some alternative implementations, the rebound force generation module includes:

[0097] The rebound force continuously adjustment unit is used to continuously increase the rebound force according to the degree of battery power consumption during the process of battery power reduction when the battery power drops below a threshold.

[0098] In some alternative embodiments, the rebound force increases with the increase of the battery power consumption value, and has an exponential trend.

[0099] In some alternative implementations, the rebound force generation module includes:

[0100] A multi-threshold drive unit is used to provide multiple different magnitudes of rebound force to the brake pedal based on multiple preset thresholds, wherein the lower the threshold, the greater the corresponding rebound force provided to the brake pedal.

[0101] In some alternative implementations, the multi-threshold driving unit includes:

[0102] A first threshold drive subunit is configured to provide a first rebound force to the brake pedal when the battery level is below 80%.

[0103] The second threshold drive subunit is used to provide a second rebound force to the brake pedal when the battery level is below 40%.

[0104] The third threshold drive subunit is used to provide a third rebound force to the brake pedal when the battery level is below 20%.

[0105] Wherein, the first rebound force is less than the second rebound force, and the second rebound force is less than the third rebound force.

[0106] In some alternative implementations, the rebound force generation module includes:

[0107] The first drive signal generation unit is used to give a first drive signal to the drive motor to rotate at a preset speed when the battery power drops below a threshold. The motor drives the resistance device through a rotating shaft to provide the rebound force to the brake pedal. The resistance device includes a first gear driven to rotate by the motor and a second gear connected to the brake pedal. When the brake pedal is pressed, the second gear and the first gear are intermittently engaged. In the engaged state, the second gear pushes the first gear to rotate, thereby giving the brake pedal the rebound force. After the first gear rotates, it disengages from the second gear and continues to engage with the second gear by the force pushed by the brake pedal.

[0108] In some alternative implementations, the rebound force generation module includes:

[0109] The second drive signal generation unit is used to provide a second drive signal with a preset pressure to the drive actuator when the battery power drops below a threshold, wherein the actuator provides the rebound force to the brake pedal by pushing the resistance.
