Detailed Description
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a functional configuration diagram of a cruise control apparatus according to an embodiment of the present invention, the cruise control apparatus including: a single cruise key 100 provided in a driver operation area of the vehicle, and the cruise key 100 is configured to transmit a cruise setting instruction in response to a user pressing operation; and the controller 200 is in communication connection with the cruise key 100 and is used for receiving the cruise setting instruction sent by the cruise key, controlling the vehicle to start a cruise function and executing the cruise setting instruction.
The cruise setting instruction refers to an instruction for instructing cruise setting after the default vehicle cruise function is started, and may include any one or more of a cruise vehicle speed setting instruction, a cruise acceleration instruction, a cruise deceleration instruction, a cruise reset instruction, and a cruise cancel instruction.
Accordingly, it can be seen that the cruise control apparatus according to the embodiment of the present invention skips the logic of turning on the vehicle cruise function, and when the cruise key 100 is pressed, directly defaults that the vehicle cruise function is turned on, and executes the cruise setting command generated by pressing the key. Therefore, the logic and the keys related to the functions of the vehicle cruise switch are omitted, the control logic is simplified, and the cost is saved.
For example, for the conventional cruise control scheme, the SET key is removed, and the conventional cruise key is pressed to directly enter a state in which the cruise speed can be SET through the scheme of the embodiment of the invention.
In a preferred embodiment, the controller 200 is configured to receive the cruise setting command sent by the cruise key, and includes: identifying a real-time pressing time of the cruise key; and confirming to receive the cruise setting instruction when the identified real-time pressing time is greater than a set time threshold, and refusing to receive the cruise setting instruction if the identified real-time pressing time is not greater than the set time threshold.
The purpose of setting the time threshold value is to prevent the driver from mistakenly touching the key to activate the cruise function, and thus to recognize the pressing time, and only the instruction exceeding the time threshold value is considered as a valid instruction and received.
For example, assuming that the time threshold is 1s, the function of the single cruise key 100 according to the embodiment of the present invention may be defined as follows:
1) defining the key pressing time to be more than or equal to 1s, and sending a cruise vehicle speed setting instruction at the moment, so that the cruise key 100 is equivalent to a conventional CEUISE key and a conventional SET key integrated with a conventional cruise control scheme;
2) and defining the key pressing time less than 1s as the misoperation of a driver, and not starting the cruise function.
In the conventional cruise control scheme, to activate the cruise vehicle speed setting function corresponding to the conventional SET key, the driver first presses the conventional CEUISE key, the vehicle activates the cruise function to wait for further operation by the driver, and the driver then presses the conventional SET key to enter the mode for setting the cruise vehicle speed. Compared with the prior art, the cruise control device provided by the embodiment of the invention can simultaneously complete the vehicle starting cruise function and the cruise speed setting function only by pressing a single key once, so that the logic of the controller for executing the corresponding cruise instruction is optimized on the software level, and the layout of the cruise keys is optimized on the hardware level.
It should be noted that, the cruise speed setting function is mainly taken as an example, but the cruise reset function, the cruise cancellation function, and the like may also be implemented correspondingly by adopting the scheme of the embodiment of the present invention.
In a preferred embodiment, the cruise key 100 is configured to generate a specific level signal when being pressed and transmit the specific level signal to the controller 200, and the controller 200 may be configured to identify a real-time pressing time of the cruise key 100, and the step of: and determining the real-time pressing time of the cruise key according to the duration time of the received specified level signal.
For example, the specific level signal may be a high level, that is, the cruise key 100 is configured such that after being pressed, the level signal of the key is changed from a low level to a high level, so that the control 200 may determine the real-time pressing time of the cruise key 100 according to the duration of the high level.
In a preferred embodiment, the controller may be a VCU. In other embodiments, a separate controller may be configured.
Taking VCU as an example, in a preferred embodiment, the controlling the vehicle to start the cruise function and execute the cruise setting command by the controller 200 includes: controlling the vehicle cruise function to be started; acquiring vehicle state information; and under the condition that the vehicle cruise function is started, judging whether the vehicle meets the preset condition for executing the corresponding cruise setting instruction or not according to the vehicle state information, and if so, controlling the vehicle to execute the cruise setting instruction to enter the corresponding cruise state. Wherein, the acquired vehicle state information may be different according to the content of the preset condition.
In the embodiment of the present invention, the cruise status includes an active status and an off status, and the transition between the two statuses based on a preset condition will be described by way of example. Fig. 2 is a CRUISE state jump logic diagram of an example of an embodiment of the present invention in which the active and OFF states are noted as active and OFF, respectively, and which exemplifies the functionality of a single CRUISE key integrating the conventional SET key and the conventional CRUISE key in an embodiment of the present invention. As shown in fig. 2, the cruise state skip logic in this example mainly includes the following:
firstly, when the current vehicle state meets the following first preset condition, the vehicle should Activate (corresponding to the active state) the cruise function.
The first preset condition includes:
1) the cruise function is in an OFF state; and is
2) There is no system three-level or above fault except the OBC (On Board of Charger) three-level fault; and is
3) The vehicle speed (the vehicle speed displayed by the instrument) is between 30 and 130km/h, wherein 30 To 130km/h is a TBD (To Be Determination, To Be defined) value; and is
4) The brake pedal is not stepped on; and is
5) The gear is in a D gear (a forward gear); and is
6) Cruise control signal states are not "0 x 0: a Not switch off cruise Control, wherein the cruise Control signal includes a CDP (Controlled Deceleration for Parking Brake) signal, a VDC (Vehicle Dynamic Control) signal, a TCS (Traction Control System) signal, and an HDC (Hill gradient Control) signal; and is
7) CDP function is not activated; and is
8) The "CRUISE" key is pressed. The CRUISE key of the embodiment of the invention corresponds to a plurality of functions; and is
9) EPB (Electric Parking Braking) signal, switch position signal is not "0 x 2: apply.
Secondly, when the following second preset condition is satisfied, the vehicle should jump from the "active" state to the "OFF" state.
The second preset condition includes:
1) the vehicle is in a non-Ready state; or
2) The fault grade is greater than or equal to grade 3 (except for OBC three-grade fault); or alternatively
3) A cruise key voltage fault; or alternatively
4) The brake pedal is stepped on; or
5) Cutting out a gear D; or alternatively
6) The cruise control signal (CDP, VDC, TCS, HDC) state is "0 x 1: switch off cruise control) "; or
7) EPB switch position signal is "0 x 2: appliance "; or
8) The "CRUISE" key is pressed.
Accordingly, the CRUISE control apparatus according to the embodiment of the present invention implements the CRUISE state switching corresponding to both the conventional SET key and the conventional CRUISE key in the conventional CRUISE control scheme by the single CRUISE key 100.
In addition, in the conventional cruise control scheme, a cruise icon and a cruise vehicle speed icon are generally provided at the instrument panel at the same time. In this regard, the solution of the embodiment of the present invention proposes a solution that only uses one icon on the basis of simplifying the logic regarding the activation of the cruise function, in view of hardware and cost. Specifically, referring again to fig. 1, the cruise control apparatus according to the embodiment of the present invention may further include: a single display 300 communicatively coupled to the controller 200 and configured to display a current cruise status.
