Description

Technical Field

[0001] This invention belongs to the field of steering wheel heating technology, specifically relating to a steering wheel heating control method, a steering wheel, and a vehicle. Background Technology

[0002] With the development of intelligent vehicles and the increasing demand for driving comfort, traditional classic models, lacking steering wheel heating, are less competitive in the market. Therefore, existing automotive manufacturers are using steering wheel heating features to enhance the competitiveness of traditional vehicles in the market.

[0003] For example, Chinese utility model patent CN 212950799 U discloses a temperature-adjustable car steering wheel, including a steering wheel body. The outer wall of the steering wheel body is provided with a heat-insulating layer, and the inner wall of the steering wheel body is provided with a connecting rod. The anti-slip and sweat-absorbing layers effectively absorb hand sweat from the driver's palms, preventing slippage and indirectly improving driving safety. The heating control device heats the steering wheel, facilitating driving in cold weather. The adjustment and temperature control modules allow for temperature regulation, tailored to individual driver needs. However, this structure requires multiple layers of composite materials, increasing manufacturing complexity and material costs, making low-cost mass production difficult. Traditional low-cost modification solutions use the cheapest materials, including controllers, wiring harnesses, heating elements, and labor. However, because the materials are not compatible with every car model, the cost is still over 600 yuan. Traditional high-end modification solutions cost over 1200 yuan. This patented heating method relies on the layout of hardware heating tubes, requiring mold redesign for different car models, resulting in poor versatility and significant difficulties in aftermarket modifications. Furthermore, it does not provide a solution for overheating during the steering wheel heating process, making it prone to overheating risks.

[0004] Therefore, a new steering wheel heating method is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a steering wheel heating control method to solve the technical problem of inaccurate temperature control in the prior art.

[0006] The present invention also aims to provide a steering wheel that employs a steering wheel heating control method, thereby solving the technical problem of high cost in retrofitting steering wheel heating in the prior art.

[0007] Another objective of this invention is to provide a vehicle.

[0008] The technical solution of this invention to solve its technical problem is as follows: A steering wheel heating control method includes the following steps: S1: Determine whether the vehicle's steering wheel heating is on. If yes, read the user-set heating level and heat the steering wheel according to the set temperature corresponding to the heating level within a first set time. Then execute step S2. If no, maintain the current state. S2: Determine whether the actual temperature of the steering wheel is not greater than the set temperature after the first set time. If yes, proceed to step S3; otherwise, turn off the steering wheel heating function, wait for the first set time, and then proceed to step S2. S3: Determine whether the actual temperature of the steering wheel is equal to the set temperature. If yes, turn off the steering wheel heating function and wait for the first set time before proceeding to step S2. If no, adjust the set temperature corresponding to the current steering wheel heating level and heat the steering wheel for the second set time. The heating temperature is a multiple of the set temperature. Proceed to step S4. S4: Determine whether the actual temperature of the steering wheel is not greater than the set temperature after the second set time. If yes, issue a heating fault reminder. If no, turn off the steering wheel heating function, wait for the first set time, and then execute step S2.

[0009] Preferably, the heating levels specifically include: a first heating level, a second heating level, and a third heating level, wherein the set temperature for the first heating level is 35 degrees Celsius, the set temperature for the second heating level is 40 degrees Celsius, and the set temperature for the third heating level is 45 degrees Celsius.

[0010] Preferably, the specific process of heating the steering wheel is as follows: within a first set time and a second set time, the first level of heating heats the steering wheel by heating the function on for 0.5 seconds and off for 3.5 seconds; the second level of heating heats the steering wheel by heating the function on for 1 second and off for 3 seconds; and the third level of heating heats the steering wheel by heating the function on for 1.5 seconds and off for 2.5 seconds.

[0011] Preferably, the first set time is 20 minutes.

[0012] Preferably, the second set time is 10 minutes.

[0013] Preferably, the heating temperature is a multiple of the set temperature, specifically: heating temperature = set temperature * 1.02.

[0014] A steering wheel employing a steering wheel heating control method includes a frame structure, a foam layer, and a wrapping layer arranged sequentially from the inside out. The frame structure of the steering wheel adopts a magnesium-embedded iron frame. A heating layer is disposed between the foam layer and the wrapping layer, and the heating layer is connected to a seat heating controller. The diameter of the steering wheel is kept constant by changing the diameter of the foam layer.

[0015] Preferably, the heating layer includes 2.0 foam and plain fabric heating pad.

[0016] A vehicle having a steering wheel employing a steering wheel heating control method.

[0017] The beneficial effects of this invention are as follows: By determining whether the vehicle's steering wheel heating is on, whether the actual temperature of the steering wheel after a first set time is not greater than the set temperature, whether the actual temperature of the steering wheel is equal to the set temperature, and whether the actual temperature of the steering wheel after a second set time is not greater than the set temperature, the invention enables the steering wheel to be heated to the set temperature corresponding to the user's needs after the user sets the heating level. Once the set temperature is reached, the heating function is turned off to avoid the risk of high temperatures caused by continuous heating. The invention also ensures the steering wheel temperature is maintained by continuously heating it for a set time. If the steering wheel temperature is lower than the set temperature after the first set time, the heating level is adjusted to the set temperature corresponding to the current steering wheel heating level, and the steering wheel is heated again for a second set time. The heating temperature is a multiple of the set temperature, further ensuring the heating effect. This achieves accurate temperature control during the steering wheel heating process.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1 As shown, this invention discloses a steering wheel heating control method, comprising the following steps: S1: Determine whether the vehicle's steering wheel heating is on. If yes, read the user-set heating level and heat the steering wheel according to the set temperature corresponding to the heating level for a first set time, then execute step S2. If no, maintain the current state. The first set time is 20 minutes.

[0021] S2: Determine whether the actual temperature of the steering wheel is not greater than the set temperature after the first set time. If yes, proceed to step S3; otherwise, turn off the steering wheel heating function, wait for the first set time, and then proceed to step S2. S3: Determine if the actual temperature of the steering wheel equals the set temperature. If yes, turn off the steering wheel heating function and wait for the first set time before proceeding to step S2. If no, adjust the set temperature corresponding to the current steering wheel heating level and heat the steering wheel for the second set time. The heating temperature is a multiple of the set temperature. Proceed to step S4. The second set time is 10 minutes. The heating temperature is a multiple of the set temperature, specifically: Heating temperature = Set temperature * 1.02.

[0022] S4: Determine whether the actual temperature of the steering wheel is not greater than the set temperature after the second set time. If yes, issue a heating fault reminder. If no, turn off the steering wheel heating function, wait for the first set time, and then execute step S2.

[0023] The heating levels specifically include: Level 1 heating, Level 2 heating, and Level 3 heating. The set temperature for Level 1 heating is 35 degrees Celsius, Level 2 heating is 40 degrees Celsius, and Level 3 heating is 45 degrees Celsius. The specific process of heating the steering wheel is as follows: within a first set time and a second set time, Level 1 heating heats the steering wheel in a heating mode that is on for 0.5 seconds and off for 3.5 seconds; Level 2 heating heats the steering wheel in a heating mode that is on for 1 second and off for 3 seconds; and Level 3 heating heats the steering wheel in a heating mode that is on for 1.5 seconds and off for 2.5 seconds.

[0024] like Figure 2 , Figure 3 As shown, a steering wheel employing a steering wheel heating control method is described. Existing technology includes a frame structure 1, a foam layer 2, and a wrapping layer 3 arranged sequentially from the inside out. This solution uses a magnesium-embedded iron frame for the steering wheel frame structure 1. A heating layer 4 is disposed between the foam layer 2 and the wrapping layer 3. The heating layer 4 is connected to a seat heating controller. By changing the diameter of the foam layer 2, the diameter of the steering wheel remains constant; that is, reducing the diameter of the foam layer 2 ensures that the diameter of the steering wheel remains unchanged even after adding the heating layer 4. The heating layer 4 includes 2.0mm foam and a plain weave fabric heating pad. In practical applications, a soft-switch control can be implemented using a vehicle information display screen. After starting the engine and powering on the vehicle, the user can open the vehicle information display screen, enter the air conditioning system page, and click the steering wheel heating icon to activate the heating function. The specific heating process is similar to that of seat heating in existing technology and will not be elaborated here. This steering wheel can be implemented in mass-produced vehicles, with a total cost increase of only 100 yuan compared to the original configuration.
