Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a vehicle according to an embodiment of the invention. As shown in fig. 1, the vehicle provided by the embodiment of the invention includes a switch 101, a vehicle body electronic stability system ESP102, a first prompter 103 and a second prompter 104, where the ESP102 includes a controller 1021 and an uphill auxiliary system HAC1022, a signal output end of the controller 1021 is electrically connected with a signal input end of the HAC1022, a signal output end of the switch 101 is electrically connected with a signal input end of the controller 1021, and a signal output end of the controller 1021 is also electrically connected with a signal input end of the first prompter 103 and a signal input end of the second prompter 104 respectively.
The switch 101 is mounted on a control panel of the vehicle, and when the driver needs to use the hill-hold function, the switch 101 will send an on signal to the ESP102, and the controller 1021 in the ESP102 will start the HAC1022 after receiving the on signal sent by the switch 101. When the driver does not need to use the hill-hold function to operate the switch 101, the controller 1021 will stop receiving the on signal sent by the switch 101 or the off signal sent by the switch 101, thereby turning off the HAC1022. In this embodiment, the switch 101 is a single pole single throw rocker switch or a self-resetting switch.
The controller 1021 detects whether the HAC1022 is normally braking the vehicle after opening the HAC1022, and sends different prompting signals to the first prompting device 103 and the second prompting device 104 according to different detection results, and the first prompting device 103 and the second prompting device 104 output different prompts after receiving the different prompting signals.
In this embodiment, the first indicator 103 is disposed on an instrument of the vehicle, and the second indicator 104 is disposed on a control panel of the vehicle. In this embodiment, the first prompter 103 and the second prompter 104 are both light emitting devices. Referring to fig. 2 in combination, the first prompter 103 is in an off state when the HAC1022 is not turned on, and is in a light-emitting state when the HAC1022 is turned on; the second reminder 104 is turned off when the HAC1022 is not braked, and is turned on when the HAC1022 is braked. Therefore, the first prompter 103 and the second prompter 104 are matched to distinguish three situations of the HAC1022 being not started, the HAC1022 being started and not braked, and the HAC1022 being started and braked. Specifically, in the case where the control panel area is limited and the number of operating devices is too large, the second prompter 104 is provided on the switch 101 in order to simplify the design of the control panel.
Further, in the state that the first indicator 103 is in the light-emitting state, whether the HAC1022 is braked may be indicated by a different light-emitting form, for example, when the HAC1022 is turned on and braked, the first indicator 103 emits light by flashing, and when the HAC1022 is turned on and is not braked, the first indicator 103 emits light continuously. This way it is avoided that the braking situation of the HAC1022 is also known by the first reminder 103 in case of failure of the second reminder 104.
For example: when the HAC1022 is not turned on, the first prompter 103 and the second prompter 104 are both in an off state, and no prompt is output; when the HAC1022 is turned on and not braked, the first prompter 103 outputs continuous light, while the second prompter 104 is in an off state and does not output a prompt; when the HAC1022 is turned on and braked, the first prompter 103 outputs a blinking light, and the second prompter 104 outputs a continuous light.
In other embodiments of the present invention, the first prompter and the second prompter may be audio players, or the first prompter may be a light emitting device, and the second prompter may be an audio player.
Further, referring to fig. 3 in combination, the esp102 includes a controller 1021 and a HAC1022, where a signal output terminal of the controller 1021 is electrically connected to a signal input terminal of the HAC1022. The hard wire signal output end of the switch 101 arranged on the control panel is electrically connected with the signal input end of the controller 1021 through the hard wire interface of the ESP102, the signal output end of the controller 1021 is electrically connected with the signal input end of the first prompter 103 arranged on the meter through the bus interface of the ESP102 and the bus interface of the meter, and the signal output end of the controller 1022 is electrically connected with the signal input end of the second prompter 104 arranged on the control panel through the bus interface of the ESP102 and the bus interface of the control panel.
In this embodiment, the switch 101 and the ESP102 communicate through a hard wire, so as to reduce the communication cost of the vehicle. ESP102 communicates with first prompter 103 and second prompter 104 through the bus, has improved the speed that first prompter 103 and second prompter 104 obtained the prompt signal that controller 1021 sent, has improved the timeliness that the user knows whether HAC1022 brakes through the suggestion of first prompter 103 and second prompter 104.
In addition, the bus interfaces on the ESP102, the engine, the instrument and the control panel all have a termination resistor and a built-in resistor, wherein the termination resistor is used for blocking reflected waves formed by bus signals at the tail end of the transmission line, so that interference on the bus signals is avoided, and the accuracy of prompt signals is improved. In this embodiment, the resistance value of the termination resistor is in the range of 110-130Ω. Since the built-in resistances of different devices are different, the total resistance value of each device is not exactly the same.
Optionally, the vehicle further includes a gateway 105, where a signal input end of the gateway 105 is electrically connected to a signal output end of the controller 1021, and a signal output end of the gateway 105 is electrically connected to a signal input end of the first prompter 103 and a signal input end of the second prompter 104 respectively.
The signal input end of the gateway 105 is electrically connected with the signal output end of the controller 1021, and the signal output end of the gateway 105 is electrically connected with the signal input end of the first prompter 103 and the signal input end of the second prompter 104 respectively. When the controller 1021 and the first prompter 103 and the second prompter 104 are in different communication protocols, the gateway 105 can forward the prompt signal sent by the controller 1021 to the first prompter 103 and the second prompter 104, so that communication between different communication protocols is realized, and the first prompter 103 and the second prompter 104 are ensured to be matched, so that different HAC states are displayed in a distinguishing mode.
Further, the bus signal input end of the gateway 105 is electrically connected to the signal output end of the controller 1021 through the bus interface of the ESP102, the bus signal output end of the gateway 105 is electrically connected to the signal input end of the first prompter 103 through the bus interface of the meter, and the bus signal output end of the gateway 105 is electrically connected to the signal input end of the second prompter 104 through the bus interface of the control panel.
By accessing the gateway 105 between the controller 1021 and the first prompter 103 and the second prompter 104 through the bus, the communication rate between the controller 1021 and the first prompter 103 and the second prompter 104 is improved on the basis of communication protocol conversion, and the timeliness of knowing whether the HAC1022 brakes through the prompts of the first prompter 103 and the second prompter 104 is improved.
The bus interface of the gateway 105 also has a termination resistor and a built-in resistor, where the termination resistor is used to block reflected waves formed by the bus signal at the end of the transmission line, so as to avoid interference to the bus signal and improve accuracy of the prompt information.
In the embodiment of the invention, the vehicle comprises a switch, an electronic stability system ESP of the vehicle body, a first prompter and a second prompter, wherein the ESP comprises a controller and an uphill auxiliary system HAC, a signal output end of the controller is electrically connected with a signal input end of the HAC, the switch is electrically connected with the controller, and a signal output end of the controller is also electrically connected with a signal input end of the first prompter and a signal input end of the second prompter. Like this, after the switch ware is opened, detect through the controller whether HAC brakes the vehicle to make first prompting device and second prompting device output different suggestion under different circumstances, thereby can let the driver know after opening HAC, whether HAC has played the effect of braking, avoid the driver to be in order to brake and actually not brake, thereby cause the hidden danger of accident.
Referring to fig. 4, the invention further provides a vehicle state prompting method, which is applied to a controller of an ESP of a vehicle, and includes:
step 201: and receiving an opening signal sent by the switch.
The switch is arranged on a control panel of the vehicle, a driver opens the switch when the auxiliary braking function of the ramp is required to be started, the switch sends an opening signal to the controller, and the controller receives the opening signal sent by the switch.
Step 202: and if the starting signal is received, sending a starting request to the HAC.
After receiving the start signal sent by the switch, the controller sends a start request to the HAC.
Step 203: detecting whether the HAC brakes the vehicle.
After the HAC receives the start request sent by the controller, the vehicle should be braked under normal operation conditions, but the vehicle may not be braked when the HAC fails to operate. By detecting whether the HAC brakes the vehicle, it is possible to detect whether the HAC plays a role in protecting braking when the vehicle is on a slope.
If it is detected that the HAC is not braking the vehicle, step 204 is executed: and sending a first signal to the first prompter so that the first prompter outputs a first prompt and the second prompter does not output a prompt.
If the HAC is detected to brake the vehicle, step 205 is executed: and respectively sending second signals to the first prompter and the second prompter so that the first prompter outputs a second prompt and the second prompter outputs a third prompt.
In the embodiment of the invention, the first prompter and the second prompter are both light-emitting devices, and the first prompter is in an extinction state when the HAC is not started and is in a light-emitting state when the HAC is started; the second indicator is in an off state when the HAC is not braked and in a light-emitting state when the HAC is braked. Therefore, the first prompter and the second prompter are matched to distinguish and display three conditions of HAC non-starting, HAC starting non-braking and HAC starting and braking. In other embodiments of the present invention, the first prompter and the second prompter may be audio players, or the first prompter may be a light emitting device, and the second prompter may be an audio player.
Further, in the case that the first indicator is in a light emitting state, whether the HAC is braked may be indicated by a different light emitting form, for example, when the HAC is turned on and braked, the first indicator emits a blinking light, and when the HAC is turned on and not braked, the first indicator emits a continuous light. In this way, the braking condition of the HAC can be known through the first indicator when the second indicator fails.
The first prompt, the second prompt and the third prompt may be the same or different on the premise that different states of the HAC can be differently prompted.
For example: when the HAC is not started, the first prompter and the second prompter are both in an extinguishing state, and no prompt is output; when the HAC is started and not braked, the first prompter outputs continuous light, and the second prompter is in an off state and does not output a prompt; when the HAC is turned on and braked, the first prompter outputs a blinking light, while the second prompter outputs a continuous light.
In the embodiment of the invention, the starting signal sent by the switch is received; if the starting signal is received, a starting request is sent to the HAC; if the HAC is detected to not brake the vehicle, a first signal is sent to the first prompter, so that the first prompter outputs a first prompt, and the second prompter does not output a prompt; and if the HAC is detected to brake the vehicle, sending second signals to the first prompter and the second prompter respectively, so that the first prompter outputs a second prompt and the second prompter outputs a third prompt. Therefore, the first prompter and the second prompter are matched, and three different prompts are output respectively under three conditions of the condition that the HAC is not started, the condition that the HAC is started and the condition that the HAC is not braked and the condition that the HAC is started and the condition that the HAC is braked are adopted, so that a driver can clearly know whether the HAC brakes a vehicle according to the prompts, and the hidden danger that the driver does not brake for braking after starting the HAC is avoided, and accidents are caused is avoided.
