Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to an integrated control handle for vehicles and a vehicle. Background Technology
[0002] In modern automobiles, windshield wipers and lighting systems are important safety assistance functions. In traditional designs, the wiper control switch and the lighting control switch are usually located on the left or right stalk of the steering wheel, respectively. The two functions are independent and physically separate, and they often use hard-wired connections to transmit signals directly to the body control module (BCM), which has problems such as complex wiring, poor anti-interference ability, and weak expandability.
[0003] With the technological advancements in vehicle electrical architecture, some vehicles have attempted to integrate wiper and lighting control functions into a single lever to achieve functional integration. However, existing integrated levers still largely rely on analog signals or simple switching signals transmitted through wiring harnesses, lacking digital communication support and limiting the scalability of intelligent driving systems. Furthermore, these integrated levers are generally part of the steering column assembly, integrally molded or fixedly mounted with the steering wheel, lacking modular replaceability. This necessitates replacing the entire steering column module during maintenance, upgrades, or adaptation to different vehicle models, resulting in high costs and low efficiency. Utility Model Content
[0004] This utility model aims to provide an integrated control handle and vehicle for use. By integrating the wiper and lighting control functions into a separately installed handle, it is easy to operate. It also introduces a microcontroller and CAN transceiver to interact with the whole vehicle, realizing the digitization, modularization and networking of wiper and lighting control signals. It has the characteristics of scalability, maintainability and high intelligence, which meets the development trend of intelligent connected vehicles.
[0005] The basic solution provided by this utility model is: an integrated control handle for vehicles, including a single handle body, a switch assembly integrated on the single handle body, and a circuit board integrated in the single handle body; a mounting base is provided at the rear end of the single handle body, and the handle is installed as the only control handle in a preset installation position on the steering wheel through the mounting base; The circuit board integrates a microcontroller, a CAN transceiver, a power processing module, and external connection ports. The switch assembly includes a washer button switch, a wiper knob switch, a headlight adjustment switch, and a lane change toggle switch that can be tossed up, down, forward, and backward. The contact points of each switch are connected to several digital input interfaces of the microcontroller via conductive connectors to output switch trigger signals to the microcontroller. The microcontroller's CAN communication pins are connected to the TXD and RXD pins of the CAN transceiver; the CAN transceiver's bus output is connected to the CANH and CANL terminals in the external connection port of the circuit board, which are used to access the vehicle's CAN bus. The power enable pin of the microcontroller is connected to the IGN terminal in the external connection port of the circuit board, which is used to input the ON / OFF gear signal of the whole vehicle. The microcontroller has a built-in CAN controller, which includes a CAN protocol engine. It is configured to encapsulate the received switch trigger signals and vehicle ON / OFF gear signals into CAN messages containing preset fields, and output them to the vehicle CAN bus via the CAN communication module and external connection port. It is also configured to receive the response messages returned by the vehicle CAN bus via the external connection port and CAN transceiver block, parse them, and output a drive enable signal to the external load drive circuit through the control signal output interface. The power processing module includes a low-dropout linear regulator, whose input is connected to the vehicle's power supply line and whose output is connected to the power pin of the microcontroller.
[0006] This utility model also provides a vehicle in which an integrated control handle for vehicles is independently installed on the steering wheel column.
[0007] The working principle and advantages of this utility model are as follows: This solution features an integrated and modular handle, enhancing integration and flexibility, simplifying driver operation, and improving driving safety. The single handle body integrates the wiper knob, light switches, and washer button into a single unit, with a rational layout, no nested parts, and a more compact structure. Its ergonomic design allows all functions to be operated with one hand, significantly improving ease of use while driving and reducing safety hazards caused by frequent switching between hands. The mounting base is designed to be both detachable and angle-adjustable, adapting to preset mounting positions on the left or right side of different vehicle steering wheels. The angle adjustment component allows for preset vertical angle adjustments (e.g., ±15°), meeting the comfort needs of drivers of different heights and driving habits, thus enhancing versatility.
[0008] This solution integrates 16 gear functions into the handle. The wiper function can be controlled by rotating the positioning cap and buttons (such as switching between OFF, intermittent, low speed, and high speed). The lighting function can be controlled by rotating the ring and the lever (such as switching between OFF, parking lights, low beam, high beam, front and rear fog lights, turn signals, and lane change). It covers the control needs of the vehicle in all scenarios.
[0009] This solution utilizes an integrated circuit board, a microcontroller, a CAN transceiver, and CANH / CANL terminals in the external connection port to achieve digital encapsulation and bus-based transmission of handle signals. Compared to existing technologies, it no longer relies on hard wiring but instead achieves digital communication through a standard CAN interface, reducing wiring harnesses, improving anti-interference, and supporting remote diagnostics and OTA. The microcontroller's built-in CAN controller uses a CAN protocol engine to locally process and generate CAN messages, improving response speed, enhancing system autonomy, and simultaneously enabling extended functions such as gear holding, updating, and timing.
[0010] This solution achieves precise power supply, while the microcontroller enables graded functions based on the vehicle's ON / OFF position signal. In the OFF position, only core lighting functions (parking lights, low and high beams) are retained to avoid unnecessary energy consumption; in the ON position, all functions are enabled, which not only complies with vehicle electrical safety specifications but also reduces the vehicle's static power consumption (static current ≤5mA) and improves range (especially for new energy vehicles).
[0011] This solution integrates the wiper and lighting control components into a single, independently mounted handle, and incorporates a microcontroller and CAN transceiver. The hardware structure supports the digital control logic, forming a new integrated solution that combines integration, independence, and communication. It achieves the digitization, modularization, and networking of wiper and lighting control signals, solving the problems of low integration, high maintenance costs, and weak communication capabilities in existing technologies. Furthermore, it features scalability, maintainability, and a high degree of intelligence, meeting the development trend of intelligent connected vehicles. Attached Figure Description

Detailed Implementation
[0013] The following detailed explanation illustrates the specific implementation methods: The basic implementation examples are as follows: Figure 1 As shown: An integrated control handle for a vehicle includes a single handle body 1, a switch assembly integrated on the single handle body 1, and a circuit board integrated within the single handle body; the rear end of the single handle body 1 is provided with a mounting base 14, through which the handle is installed as the only control handle in a preset mounting position on the steering wheel. The circuit board integrates a microcontroller (MCU), a CAN transceiver, a power processing module, and external connection ports. The switch assembly includes a washer button switch 11, a wiper knob switch 12, a headlight adjustment switch 13, and a lane change toggle switch that can be tossed up, down, forward, and backward. The contact ends of each switch are connected to several digital input interfaces of the microcontroller through conductive connectors to output switch trigger signals to the microcontroller. The microcontroller's CAN communication pins are connected to the TXD and RXD pins of the CAN transceiver; the CAN transceiver's bus output is connected to the CANH and CANL terminals in the external connection port of the circuit board, which are used to access the vehicle's CAN bus. The power enable pin of the microcontroller is connected to the IGN terminal in the external connection port of the circuit board, which is used to input the ON / OFF gear signal of the whole vehicle. The microcontroller has a built-in CAN controller, which includes a CAN protocol engine. It is configured to encapsulate the received switch trigger signals and vehicle ON / OFF gear signals into CAN messages containing preset fields, and output them to the vehicle CAN bus via the CAN communication module and external connection port. It is also configured to receive the response messages returned by the vehicle CAN bus via the external connection port and CAN transceiver block, parse them, and output a drive enable signal to the external load drive circuit through the control signal output interface. The power processing module includes a low-dropout linear regulator, whose input is connected to the vehicle's power supply line and whose output is connected to the power pin of the microcontroller.
[0014] Specifically, such as Figure 2 and Figure 3 As shown: The water spray button switch 11 is located on the front end of the single handle body. It triggers the water spray signal and has a self-resetting structure. Pressing this switch enables water spraying for dust removal and self-resetting.
[0015] The wiper knob switch 12 includes a rotatable positioning cap and a button, located at the front end of the single handle body. Rotating the positioning cap switches the wiper control (MIST, OFF, INT, LO, HO). Rotating it sequentially by a first preset angle triggers the inching / manual MIST, OFF, intermittent INT, low-speed LO, and high-speed HO mode signals. It also has a self-resetting function in the inching / manual mode. Figure 4 As shown, the first preset angle is 21-23°, preferably 22°5′.
[0016] The headlight adjustment switch 13 includes a rotating ring and a toggle lever mounted on the rotating ring, located on the side of the single-handle body. Rotating the toggle lever switches the headlight control. Sequentially toggling the lever to a second preset angle triggers the OFF, parking light, low beam, and fog light position signals, and it has a self-resetting function in the fog light position. Figure 5 As shown, the second preset angle is 14-16°, preferably 15°.
[0017] Furthermore, red LED indicators are installed next to each switch, allowing drivers to intuitively determine the current gear by observing the red light, thus avoiding danger caused by looking away from the road to check the gear. This significantly improves operational safety, especially at night or in inclement weather.
[0018] like Figure 2 As shown, moving the lane change toggle switch forward or backward triggers the right turn D1 and right lane change D2, and the left turn D3 and left lane change D4 indicator signals; as Figure 3 As shown, moving the toggle upwards triggers the overtaking D5 signal and has a self-reset function, while moving it downwards triggers the high beam D6 signal and has a self-reset function.
[0019] like Figure 6 The diagram shows the electrical connection logic of the handle trigger structure. By sliding the moving contact 2, it can make contact with different stationary contact pieces, thereby triggering different functions (left turn, left lane change, right lane change, right turn).
[0020] Specifically, the movable contact 2 is a sliding rail that can slide along the movable contact 2 ( Figure 5(Indicated by double arrows) The moving conductive piece. It is an actively moving component that selects to contact different stationary contacts by changing its position. The stationary contact (common terminal) is the common connection point of the circuit, providing a fixed electrical connection terminal for the moving contact 2 (similar to the "common pole" of a circuit). The stationary contact (position terminal) is divided into four positions: "left turn," "left lane change," "right lane change," and "right turn," which are target contact terminals for different functions. In this embodiment, left turn and left lane change use the same contact terminal, and right turn and right lane change use the same contact terminal. Using the same contact and sending the same message, the state is distinguished by the duration. Since the turning spatial angle is small, this scheme can effectively reduce the contact deviation problem caused by unstable tolerance dimensions, and the product precision can also be relatively reduced, thus reducing mold opening costs.
[0021] The triggering logic is as follows: when the handle is operated, the moving contact 2 moves along the sliding rail and contacts the stationary contact at different gear positions. If the moving contact 2 slides to and contacts the "left turn / left lane change" stationary contact, the circuit path for the "left turn / left lane change" function is triggered. Similarly, if the moving contact 2 slides to and contacts the "right turn / right lane change" stationary contact, the circuit path for the "right turn / right lane change" function is triggered. Under the timing logic control implemented by the microcontroller, the lane change light is activated as follows: the lane change function is triggered when the left / right turn signal is turned on to off within 0.7 seconds; the left / right turn signal is triggered when the left / right turn signal is turned on to off within 0.7 seconds. The left / right turn signal and the left / right lane change signal are shared.
[0022] The driver can control the lights and wipers by rotating, tossing, and pressing buttons with one hand. After the driver becomes familiar with the switches for a while, they can operate the switches to achieve the required functions while keeping their eyes on the road, depending on the actual vehicle situation. This reduces driver distraction and improves the driving experience and safety.
[0023] The circuit board provided in this embodiment is as follows: Figure 7 As shown, the power processing module, specifically integrated within mounting base 14, includes a low-dropout linear regulator (LDO). The circuit board's external connection ports include PIN10 BAT and PIN5 GND. PIN10 BAT is connected to the LDO via a diode, and the LDO's output is connected to the microcontroller's power supply pin. PIN5 GND is grounded. The voltage input from the vehicle's power supply line via PIN10 BAT is converted to a stable VCC voltage by the LDO after passing through the diode, thus powering the microcontroller (MCU).
[0024] The circuit board has external connection ports including PIN3 CANH terminal and PIN4 CANL terminal; the CAN transceiver connects to PIN3 CANH terminal and PIN4 CANL terminal through its CANH and CANL pins respectively, and its TX and RX pins connect to the CAN communication pins TX and RX pins of the microcontroller to realize communication between the MCU and the vehicle CAN bus.
[0025] The circuit board has external connection ports including a PIN6 IGN terminal, which is used to connect the vehicle's ON / OFF gear signal line to the microcontroller.
[0026] The microcontroller, as the core control unit, interacts with the switch combination to trigger the switch gear position, interacts with the vehicle to transmit ON / OFF gear position signals, and exchanges CAN control messages and response messages with the vehicle's CAN network via the CAN controller and CAN transceiver. It also interacts with the external load drive circuit to exchange drive enable signals. This allows control of the vehicle's lights, wipers, and other systems via the handle. For example, for the wiper / washer: pressing the wiper / washer button sends a wash message; pressing for more than 20 seconds will stop sending the wash message. For the ignition signal: after the IGN is disconnected, the shift / light handle stops sending messages and enters sleep mode. Additionally, after the vehicle is turned off and parked, the "Follow Me Home" function can be activated upon arming, automatically cutting off all lights and wipers to ensure the vehicle enters a low-power state. In this embodiment, the MCU can be an S32K144 model, and the CAN transceiver can be a TJA1050 model.
