Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of description of the present application, and have no specific meaning by themselves. Thus, "module", "component" or "unit" may be used mixedly.

Because a conventional steering wheel key unit generally only has one function, the function cannot be changed at will, the general steering wheel key unit is connected with an associated control unit by using a hard wire, the associated control unit judges the key significance by different currents generated by different resistors on a steering wheel, the physical connection does not support a user to change the key significance at will, and the key is connected into a specific associated control unit and can only be used by the associated control unit but cannot be reused by other associated control units.
The invention provides a key configuration module which comprises a steering wheel key unit, a single chip microcomputer control unit, a vehicle body control unit and an associated control unit which are sequentially connected; the steering wheel key unit comprises a plurality of physical keys; the association control unit comprises a plurality of function controllers; when the physical key is pressed, the single chip microcomputer control unit sends the received key signal to the vehicle body control unit, the vehicle body control unit forwards the key signal to the CAN bus according to a preset key function, and the function controller corresponding to the preset key function executes a function corresponding to the physical key according to the key signal. The vehicle comprising the key configuration module is provided with the key function configuration method, the steering wheel key unit is endowed with reusability and one-key-multiple use, unified signal forwarding is carried out through the BCM, signals are broadcasted through the CAN bus, the situation that one key CAN only be used by one controller is not limited any more, the key function CAN be more reasonably and rapidly expanded, and further the individual requirements of drivers are met.
Referring to fig. 1 and fig. 2, an embodiment of the present invention provides a key configuration module, and as can be seen from fig. 1, the key configuration module includes a steering wheel key unit 100, a single chip microcomputer control unit 200, a vehicle body control unit 300, and an associated control unit 400, which are connected in sequence; as can be known from fig. 2, the steering wheel key unit 100 is electrically connected to the mcu 200; the single chip microcomputer control unit 200 is connected to the vehicle body control unit 300 through an LIN (Local Interconnect Network) bus; the vehicle body control unit 300 and the association control unit 400 are connected by a CAN (Controller Area Network) bus;
the steering wheel key unit 100 includes a plurality of physical keys, such as keys 1 to 8 listed in fig. 2;
the associated control unit 400 includes a plurality of function controllers, such as an in-vehicle entertainment system, an instrumentation system, and a smart driving system listed in fig. 2;
when the physical key is pressed, the single chip microcomputer control unit 200 sends the received key signal to the vehicle body control unit 300, the vehicle body control unit 300 forwards the key signal to the CAN bus according to a preset key function, and the function controller corresponding to the preset key function executes a function corresponding to the physical key according to the key signal.
That is, when the physical key is pressed, the single chip microcomputer control unit 200 converts the received key signal into an LIN signal and transmits the LIN signal to the vehicle body control unit 300, the vehicle body control unit 300 converts the LIN signal into a CAN signal according to a preset key function and forwards the CAN signal to a CAN bus, and the function controller corresponding to the preset key function executes a function corresponding to the physical key according to the CAN signal.
It should be noted that although the steering wheel key unit in fig. 2 only includes the keys 1 to 8, the number of physical keys in this embodiment is not limited, and the resistances of 0k, 1k, 4.7k, 3.3k, 2.7k, 3.9k, and 6.8k included in the key circuit in fig. 2 do not limit the resistance value and the position in practical application. The preset key function is set by a user, for example, the user sets the key 1 as "speed up", after the key 1 is pressed down, a "speed up" signal is sent to the CAN bus through the single chip microcomputer control unit 200 and the vehicle body control unit 300, the corresponding function controller is an intelligent driving system, and the intelligent driving system executes the action of vehicle acceleration after acquiring the "speed up" signal on the CAN bus. For example, if the user sets the key 8 to "volume down", the key 8 is pressed, and then a "volume down" signal is sent to the CAN bus via the single chip microcomputer control unit 200 and the vehicle body control unit 300, the corresponding function controller is a vehicle-mounted entertainment system, and the vehicle-mounted entertainment system executes an action of reducing the audio volume in the vehicle after acquiring the "volume down" signal on the CAN bus.
In this embodiment, the keys are not connected to the controller through a pure hardware circuit of a resistor and a capacitor, the steering wheel key signals are converted into LIN signals to be sent to the vehicle Body controller (i.e., the vehicle Body Control unit 300) through a single-chip controller (i.e., the single-chip controller unit 200) in a unified manner, then the LIN signals are converted into CAN bus signals in a unified manner by a BCM (Body Control Module, the vehicle Body controller), and the CAN bus signals are periodically sent to the CAN bus to be used by the associated Control units 400 such as the instrument system, the vehicle-mounted entertainment system, and the intelligent driving system.
The problem that a single physical key cannot be multiplexed by a plurality of controllers can be solved through the bus form.
In addition, based on the key configuration module, a user can customize the function of each key through a vehicle-mounted entertainment screen setting interface or through voice control. For example, a request instruction is sent by the vehicle-mounted entertainment system, and the BCM controller re-pairs the key and a CAN bus signal sent by the vehicle-mounted entertainment system, so that the user-defined purpose CAN be realized. The customized keys cannot cause the change of the CAN matrix, so that the software modification of the associated controller is not caused, and the BCM CAN automatically match the relationship between the keys and the CAN signals.
For example, a user sets the key 1 to be 'speed up' by using a voice service vehicle-mounted entertainment system, after receiving an instruction, the BCM detects that the key 1 is pressed, and then matches the key 1 to a CAN signal 'speed up' and sends the CAN signal 'speed up' to a CAN bus for an intelligent driving system to use. Correspondingly, if the user modifies the key 1 into volume plus through the vehicle-mounted entertainment screen, the BCM receives the instruction and detects that the key 1 is pressed down, and then the key 1 is configured to the CAN signal and modified into volume plus for the vehicle-mounted entertainment system to use.
